Warhammer 40,000

It is the 41st millennium. For more than a hundred centuries the Emperor has sat immobile on the Golden Throne of Earth. He is the master of mankind by the will of the gods, and master of a million worlds by the might of his inexhaustible armies. He is a rotting carcass writhing invisibly with power from the Dark Age of Technology. He is the Carrion Lord of the Imperium for whom a thousand souls are sacrificed every day, so that he may never truly die.

Yet even in his deathless state, the Emperor continues his eternal vigilance. Mighty battlefleets cross the daemon-infested miasma of the warp, the only route between distant stars, their way lit by the Astronomican, the psychic manifestation of the Emperor’s will. Vast armies give battle in his name on uncounted worlds. Greatest amongst His soldiers are the Adeptus Astartes, the Space Marines, bio-engineered super-warriors. Their comrades in arms are legion: the Astra Militarum and countless planetary defence forces, the ever-vigilant Inquisition and the tech-priests of the Adeptus Mechanicus to name only a few. But for all their multitudes, they are barely enough to hold off the ever-present threat from aliens, heretics, mutants – and worse.

To be a man in such times is to be one amongst untold billions. It is to live in the cruellest and most bloody regime imaginable. These are the tales of those times. Forget the power of technology and science, for so much has been forgotten, never to be re-learned. Forget the promise of progress and understanding, for in the grim dark future there is only war. There is no peace amongst the stars, only an eternity of carnage and slaughter, and the laughter of thirsting gods.

Part One

One

‘We live and die for Huron Blackheart!’ shouted Garreon.

As the gathered officers of the Red Corsairs raised their fists and shouted ‘Aye!’, Captain Rotaka shouted as loud as any of them.

For Huron Blackheart they lived, and for Huron Blackheart they waited.

The lord of the Red Corsairs had gathered his commanders for one last feast before the invasion, to remind them of who they served, and the depth of his wrath should they fail him.

They were aboard the Might of Huron, flagship of the Red Corsairs fleet. Three decks below bridge level, the commanders met in an open area vaulted with dripping girders, condensation from life support and coolant tubes running down the walls to form murky pools of liquid.

With all powered functions on ship reduced to the bare minimum as the fleet approached its destination, the light in the chamber came from guttering flames – slaves had dragged in great piles of refuse, placed them in wide bowls, doused them with oil and set them alight. The smoke was foul, the flames spitting and hissing.

The Red Corsairs did not rest on the high ceremony beloved of the hated Imperium and the bloodless loyalists who retained faith in their damnable Corpse-Emperor. Instead there was simply service and reward: they gave unquestioning service to their master, and in return he rewarded them with a share of the spoils, as he saw fit.

Such a gathering of the Red Corsairs senior officers should, by that theory, have been devoid of formality, and indeed for the most part the arrangements were simple: the officers attended, and slaves brought them fine foods and drinks, plundered from a hundred worlds and countless ships.

In practice, although they were traitors to the cause they remained Space Marines, and the physical pleasures of eating and drinking were of limited interest to them. Equally, while they professed an abandonment of their former conventions and an embracing of anarchy, the Red Corsairs were still born soldiers, and any gathering was riven by complex strata of rank and achievement.

There were also newer traditions, traditions which would have been utterly repugnant to the gathered Red Corsairs under their former colours – rituals and ceremonies that had developed since their master embraced the faith of Chaos Undivided.

One such tradition was that involving the Cup of Blessings.

Rotaka had entered the gathering of officers precisely on time. While he followed his master into the service of Chaos, as he would follow him anywhere he was required to, Rotaka took little interest or pleasure in the practice of his adopted faith. He simply served his lord as he had since he had been elevated to the ranks of the Adeptus Astartes, and while his master’s loyalties may have changed, Rotaka’s more narrow loyalties had not.

To follow one’s master into the depths and fight on, that was true service.

He surveyed the room. Even on this, one of his master’s more personal and obsessive campaigns, the full complement of Red Corsairs officers was not present. The Red Corsairs had their stronghold within the Maelstrom along with other holdings, and smaller fleets that had been sent out to menace Imperial shipping lanes and were long out of contact with command. They were a warband, not a Chapter, and their reach was vast. It made a true gathering of the captains almost impossible.

Still, many of them were here, including some of their lord’s closest allies.

One such luminary was Garreon the Corpsemaster, Chief Apothecary of the Red Corsairs. Amongst the near-identical ranks of former Astral Claws, Garreon stood out with his sharp, scarred features and impenetrably dark eyes, his greying brown hair falling to his shoulders. He somehow seemed to stand taller than those of identical height as he impassively surveyed the chamber.

His eyes did not meet Rotaka’s, though the latter could not tell whether this was accident or calculated sleight. Rotaka truly didn’t care. Garreon was a formidable opponent and while Rotaka did not wish to cross him, neither did he feel the need to court the Corpsemaster’s favour.

In this he was obviously alone; while Garreon stood apart from the throng, the other officers took turns to step up to him and pay a few words of homage. This sickened Rotaka, although he could not quite place why.

Of the others, Rotaka saw Valthex, the Red Corsairs Chief Techmarine, ignoring everyone around him and checking a data-slate, as was his habit. While the other Red Corsairs had mostly abandoned their helmets, Valthex remained hidden beneath his. He was still carrying the bulk of the unique array of ancient machinery, mounted on the shoulders of his armour. He moved amongst his peers like an oblivious tank, a giant amongst giants.

The rest? Rotaka thought little of them, except in memories of old campaigns. He realised that he was one of the few still adorned as he had been the day after they struck away their old insignia and adopted the red saltire of the Corsairs.

In that chamber he saw hands that had steadily mutated into great, crab-like claws, pauldrons edged with brass trim, an increasing number of modifications and trophies. One Red Corsair had both cheeks pierced with rows of silver thorns, while another wore a hood of gold chains over his head, his misaligned eyes suggesting some severe mutation or injury beneath the glittering mask.

‘Let us drink, brothers,’ said a velveteen voice, cutting through all other noise in the room. Rotaka turned to see who had spoken, and found it hard not to spit on the floor at his use of the word ‘brothers’.

The speaker was Anto, formerly of the disbanded Tiger Claws Chapter, secretly adopted into the Astral Claws under circumstances which even Rotaka was still not fully aware of, decades later. Anto’s expression was unreadable beneath an ornate cylindrical helmet with horizontal, dark eye-slits, but Rotaka imagined it was one of infuriating smugness at his ability to command a crowd.

Anto considered himself a keeper of secrets, above or equal to all except their master, but Rotaka had other opinions. The surviving former Tiger Claws were born traitors and vicious survivors who had, with his master’s blessing, hidden themselves amongst the ranks of the Astral Claws long before Rotaka’s Chapter had rejected the Imperium and become the Red Corsairs. Rotaka had no doubt that, should circumstances favour it, the likes of Anto would abandon the Corsairs as they had all other prior loyalties, and seek to continue their own mysterious practices elsewhere.

Whatever secrets the Tiger Claws brought with them to secure the favour of Rotaka’s master, Anto remained one of the keepers. A sorcerer of considerable power, his power armour was partially concealed beneath a long cloak of dark red fabric, tattered from countless battles. He carried a tall staff of ornate iron, adorned with a spiralling engraving that either resembled or actually was a series of human spines curling round the shaft.

For all Rotaka’s distrust of the former Tiger Claw, he knew it was unwise to snub Anto, especially when he was currently in their master’s favour due to his role, alongside Garreon, in preparing the ground for the current campaign.

So Rotaka joined his fellow officers in forming a single ritualistic circle in the room. Only Garreon and Valthex stood outside the circle, taking a position behind Anto’s shoulders as he prepared to lead the ceremony, holding in his hands an ornate silver chalice. The engravings on the cup seemed to shift when looked at directly, skulls and twisted faces writhing on the surface.

The Cup of Blessings. To drink from the cup was a ritual performed amongst the Red Corsairs before great battles. Not all would drink, and indeed not all battles would see Anto produce the cup first. The criteria for when the cup was used, and by whom, were known only to Anto himself.

Anto spoke words Rotaka could not comprehend and made gestures over the cup, then walked to one corner of the room where a trickle of water poured from a hole in the ceiling and held the cup under it, filling it.

‘What enters the cup matters not,’ said Anto. ‘The cup blesses its contents as it blesses those who drink from it. It transforms liquid as it transforms life.’

Rotaka had heard these words countless times before and suppressed a sneer at Anto’s relentless sense of theatre, keeping his face a mask.

‘The cup chooses who drinks from it,’ said Anto. He walked over to a Red Corsair called Becaro, holding the cup before him as if pulled by some invisible force. Becaro took the cup and poured some of the liquid into his mouth.

The ‘blessings’ bestowed upon those who drank from the cup in these pre-battle rituals were varied in nature. For some, the elixir changed nothing. For others, it brought a temporary gift, a mystical power or ability of use in the coming battle that would fade with time. Others would receive the more permanent blessing of a mutation, warping them into a form more pleasing to their gods.

But for many, it simply brought death. Painful, retching death as the elixir burned through them.

Becaro grunted with pain and doubled over, clutching his stomach. Then he raised his head and released a peal of deep laughter. He lifted his hands to show the others, and as he did so green flame crept from his wrists to consume his gauntlets. He flexed his fingers, flinging sparks of spectral fire.

‘A true blessing,’ enthused Anto. ‘Becaro is most favoured.’

This time Rotaka could not quite suppress his contempt, and felt a twitch of disgust pass across his face. He didn’t care for the tricks of sorcerers.

Anto’s head snapped round to stare straight at Rotaka. He said nothing, but moved his entire body around towards him, and raised the cup. ‘Rotaka, will you drink?’

As surely as Rotaka knew that Anto was a walking curse who brought nothing but betrayal and destruction to those around him, so Anto surely knew that Rotaka’s faith in the gods their master had sworn them to was limited. If the cup truly tested faith to decide who was worthy of a blessing, then it would reject and destroy Rotaka with a single mouthful.

Equally, a straight rejection of Anto’s offer would be a rejection of their shared gods, and the faithful would not hesitate to hack Rotaka down where he stood, regardless of his rank.

Rotaka looked down into the chalice. The water in the cup had turned into a thick elixir of indeterminate colour. There did not seem to be much of the liquid left after Becaro’s long gulp.

‘Will you not sup first, brother?’ Rotaka asked Anto. ‘I would hate for the bearer of the cup to be deprived of the chance to be blessed. Your stewardship makes you worthier than I for its rewards.’

Anto’s helmet made his expression unreadable as he looked back at Rotaka, as if weighing the sincerity of the proposal.

‘I will,’ said Anto. ‘You do me great honour by offering to let me sup before you.’ He turned to the others. ‘Please, favoured Becaro, would you hold the cup and my staff for one moment while I prepare.’

Becaro did so, laughing once more as the flames around his hands licked the staff and cup as he held them. Meanwhile Anto, who Rotaka had not seen remove his helmet in many decades, reached behind his neck and released the clasp that attached it to his power armour.

With a hiss, the helmet came away, and the sorcerer revealed his true face. If he was self-conscious about his appearance, either due to pride or self-disgust, he did not show it, and neither did those around him react to the change in his appearance over the long years.

The ravages of experimentation with the powers of Chaos were written across Anto’s features. His jaw was lopsided, the teeth on one side of his mouth crooked and over-sized. A diamond shaped patch of skin on one cheek was scaled like that of a lizard, purplish and rough. His scarred scalp was hairless except for patches of dark, wiry fur. Even his ears were tapered, and while one of his eyes was piercingly dark the other was slack-lidded, coloured a milky blue with no visible iris.

‘I accept any blessing the gods may choose to bestow upon me,’ said Anto, taking the cup back from Becaro and lifting it to his lips.

A gulp taken and swallowed, Anto passed the cup to Rotaka, who couldn’t help but glance down and note that there was still a sip’s worth of elixir lingering in the bottom. He had not escaped his fate just yet.

Rotaka looked up, and found Anto holding his gaze, the slack eye more alert than it first appeared. Then Anto’s gaze became glassy; he swayed slightly on the spot and began to cough fiercely.

For a few precious seconds, Rotaka thought that it was he who had been blessed, that the sorcerer was going to die and he could cast aside the hated cup in the confusion.

But Anto’s coughing ended not in death but in a large exhalation of fine purple smoke, and a blissful expression utterly alien to a genetically bred warrior. Whatever he saw in that moment, it was not the chamber they were in.

Then Anto’s eyes snapped back to normal, and his shoulders straightened. As the smoke cleared, he replaced his helmet.

‘A vision,’ he said. ‘A minor blessing, but a welcome one.’ He did not elucidate further.

Rotaka knew that to delay further would be of no use. ‘May I be so fortunate,’ he told Anto, lifting the cup to his lips and draining the last, thin trickle of liquid. He tried to slip it past his tongue, presuming it would taste worse than anything he had ever drunk before, but to his surprise it tasted of… nothing. Less than nothing. An absence of taste. It did not even feel like liquid, but a sense of passing dryness.

Dry. Wet. Stomach full. Stomach empty. Pain. No pain. Hot. Cold. Breathing. Suffocating. Burning. Freezing. Muscles tight. Muscles loose. Light. Dark.

The elixir spread throughout his system in seconds, causing all his senses to flare in contradictory directions. Then the sensation passed, and he was somewhere else altogether. A frozen moment of time.

He was in that hidden room within the Palace of Thorns, still wearing the colours of the Astral Claws. Iltz, wearing those same colours, was on his knees beside him. A pipe, ripped from the wall in their fight, pushed down by Rotaka into Iltz’s neck. The blood exiting the wound, the look of mutual betrayal, brotherhood festered into hatred, exchanged by the dying and their killer. The tension through the length of pipe as it was pushed down, slippery with rust and oily water, the strain and exhilaration of combat. The certainty and confusion of following a cause, deeply believed in, to places absolutely uncertain. The fading life in the eyes of a former friend.

That moment, too, passed and Rotaka was back in the present. In one hand, he held the Cup of Blessings. In the other, he could still feel the weight of that improvised weapon.

‘Brother?’ asked Anto.

Rotaka passed him the cup. He thought carefully, and decided to answer truthfully, but not in a way that needed to be comfortable. He had passed Anto’s test.

‘A vision too, of another time,’ he replied, holding the blank gaze from Anto’s helmet. ‘Of striking down a brother for an act of treachery.’

‘A useful insight, I hope,’ said Anto.

‘A blessing from the gods will always prove useful,’ replied Rotaka.

‘Of course,’ said Anto, returning the cup to some hidden pouch beneath his robe, before addressing all of them. ‘Three of us have drunk of the Cup of Blessings, and all survived. Our enterprise is well fated.’

‘Fate?’ boomed a harsh, gravelly voice as the chamber’s doors were thrown open. The newcomer entered, flanked by bodyguards in Terminator armour. ‘Fate and the gods provide opportunity, but it is for us to seize those opportunities, and squeeze victory from the chances the gods give us.’

The gathered officers of the Red Corsairs parted as their lord, their master, Huron Blackheart, strode to the centre of the chamber. He towered over the greatest of them, dominant even in a room of demigods and sorcerers. He wore blood-red power armour, cracked and aged and emblazoned with a gold eight-pointed compass, the symbol of Chaos. A Sigil of Corruption arced behind his head like a perverse halo.

His skin was grey, dead, with patches of bone visible, augmented by bionics including the Tyrant’s Claw, an adapted power claw with built-in flamer that made up his entire right arm. As he prowled the chamber, he moved around the Corsairs, the claw flexing as if it might crush the skull of one of his underlings at any time.

Rotaka felt the fear in the room aboard the flagship, but did not share the trepidation. His master was uncompromising, but just, and Rotaka knew that if he served him well he had nothing to fear. He had followed him into the abyss and back out again, and would not have done so if he did not believe in his judgement.

His recent flashback to that day in the Palace of Thorns still lingered with him. He knew as well as anyone the hard decisions of leadership, and the need to harshly deal with betrayal.

‘Our gods I thank for providing opportunity,’ Huron said, his voice cutting through the silence of his servants. He raised his claw and gestured around the room, pointing at all of them but pausing on both Garreon and Anto along the way. ‘But it is you, my Red Corsairs, who I entrust to carry out my battle plans, to fulfil your part in my campaign, to die in doing so if required.’

Blackheart’s meaning was clear – that even in death, failure would not be tolerated, and that to fail and live would only bring a greater suffering. Rotaka felt a swell of energised pride that he would not allow himself to fail his master.

‘Our prize is great, the challenge it presents greater,’ said Huron, striding around a central point in the chamber, his Corsairs backing away to make room. ‘Valthex.’

The Techmarine stepped forwards, and a hololithic projector built into his armour created a flickering three-dimensional image in the air at the centre of the chamber. Nine spheres, most of them cloaked in a miasma. As they moved around each other the image glitched and some of the spheres jumped from one place to another, as if the person who had made the hololith was extrapolating from incomplete information.

‘The Hollow Worlds of Lastrati,’ said Huron, audible hunger in his voice. ‘Nine hollow spheres, planets inhabited on their inner surfaces, under the possession of the hated Corpse-Emperor. Consumed by the impassable Siren Clouds, our closest access point is the Hellward Gate on the outer surface of Laghast,’ said Huron, the hololith enlarging until one of the outer planets filled the space. An orbital dock and buildings on the planet’s desolate outer surface appeared. ‘We have worked long and hard to break these defences, and even now Taemar is close to shattering the final link. When those defences fall, we strike.

‘We will crack open these Hollow Worlds, and the callow mortals who live within them will bow to new masters.’

There was a further series of ‘ayes’ around the chamber, raised fists and jubilation. Rotaka felt his pride swell again, but also a sense of trepidation that all their hopes rested on Garreon, Anto, and of course the absent Taemar.

Rotaka wished he could believe those hopes were well placed.

Two

Outstation One was a satellite connected to Plini, one of the Hollow Worlds. While Laghast was protected by a conventional, though vast, array of space-based defensive systems, Plini’s main defence was that its exterior was almost impossible to land a ship on. The mile-high rock formations prevented it, and the irradiated surface would kill anything that tried to set up the elaborate drilling operation required to break through to Plini’s inhabited interior.

The staff aboard Outstation One and Plini’s other artificial moons had to travel via Laghast to get in and out of the system, the only connection between these satellites and the planet below being the vast algae-encrusted chains that stretched from the orbiting spheres to the surface of Plini. As with so much about the Hollow Worlds, no one knew who had built the satellites or why. However, the Lastrati had fitted it out as an early warning station and communications relay, catching and boosting signals as they went into and out of the Hollow Worlds and the disruptive Siren Clouds.

Taemar picked up the adept’s severed head and turned to address his squad.

‘The satellite is guarded by tech-guard, unknown numbers,’ he said. ‘No match for us, but let’s take the objective before they know we’re here.’

It was then that they heard a distant siren. Taemar swore. One of his squad, Rioss, pointed upwards.

High above, on the other side of the outstation, figures were exiting a cluster of buildings. While Taemar was aware from his briefings that flight was impossible in the Hollow Worlds due to the artificial suns, he also knew that the outstation had no such constraints. He could see the figures lifting off into the air, presumably using jump packs, crossing the space between them and his squad with incredible speed, flying in formation.

No, not just flying, thought Taemar. Swarming.

The tech-guard were coming.

The tech-guard aboard Outstation One had been specially modified to maximise resource management aboard the remote station, their brains and bodies adapted to allow them to spend long periods dormant, yet be ready to attack in seconds. To facilitate rapid deployment, weapons had been built into their forelimbs.

Many signals could wake the tech-guard. Taemar and his squad had breached the outstation without having triggered any of the obvious alarm systems. However, in killing the adept after interrogating him for information, Taemar had caused a life sign monitor built into his chest to stop transmitting, and it was that which had raised the alert.

Their stripped-down biology flooded with adrenaline, lobotomised brains conditioned only to kill, pumped to a state of alert in seconds, the tech-guard rushed out of their hive-like barracks with simple orders in mind:

Find the intruders. Kill the intruders.

Taemar should have let his squad provide covering fire while he ran to the location of their target and proceeded with his mission. That would have been the most loyal and honourable course of action, and Taemar would have usually done so, for appearances’ sake if not from any actual devotion.

However, looking up into the sky as the tech-guard descended, his ego prevented him from following a cautious plan of action. His lip wrinkled with contempt for these insectoid humans. As they started firing, las-shots raining down from above, Taemar adjusted his grip on his axe.

How dare these flimsy mortal things attempt to strike him down? He was Taemar of the Red Corsairs, and he would crush these creatures without remorse. He had spent many days trapped aboard a small pod with his squad to reach Outstation One, and had plenty of anger to work through. These attackers would provide the perfect outlet.

As the tech-guard descended from the sky, and the rest of the squad started to return fire, Taemar dropped into a crouch and…

…and jumped.

A combination of weak gravity and Taemar’s immense physical strength allowed him to leap high into the air. As he leapt he swung his axe around in an arc before him, cleaving three or four of the tech-guard into a shower of metal pieces and bones as he smashed through their front line.

The tech-guard swarmed onto him as he jumped, some feeling the cut of his axe but others scratching at his power armour with the sharpened ends of their metallic limbs, trying to pull the plate away, clawing towards his helmet-less head, a dozen pale, humanoid faces with compound eyes and blackened teeth chittering at him.

As they piled onto Taemar, he reached the peak of his ascent, and fell. His assailants, clinging and clawing at him were dragged down as he fell like a meteor.

He landed on his feet, smashing into the ground with incredible force, the shock throwing off his attackers in a tumble of twisted limbs and screeching mouths.

Then he was up, a towering figure, blood dripping from countless small cuts on his cheeks and forehead, piling into the massed tech-guard as they fired upon him and fruitlessly raised clawed limbs against him, the axe dripping with sluggish dark blood and watery artificial fluids as it swung back and forth, hacking the forces of the Adeptus Mechanicus to pieces.

As those who had landed were butchered, other tech-guard attempted to gun him down from a safe distance, but then Taemar’s squad – who had so far been fighting a much harder battle against the hordes of oncoming enemies – grouped together to gun down the fliers with their bolters, the sky lighting up with explosions.

Blood and metallic fragments rained down, and in the centre of the carnage was Taemar, still cutting through three or four attackers at a time.

The last few tech-guard tried to withdraw and regroup, but it was too late. The Red Corsairs’ bolters flared, and the final attackers were brought down.

Then all was silence. Taemar breathed deeply, taking in air tainted with blood and cordite and the oily stench of burned, broken machinery. He looked upon his squad, whose armour was dented and scorched from the attacking tech-guard, and laughed out loud, throwing his axe in the air so it spun, then catching it by the handle.

‘Is the blocking signal still working?’ he asked his men.

Rioss consulted a hand-held auspex. ‘Block still in place,’ he confirmed. Taemar noticed that the Red Corsair had a blast wound in one side of his chest. ‘Whatever alert may have been raised here, it won’t have left the station.’

‘Good,’ said Taemar, returning his axe to its place on his back as he did so. ‘Let’s find what we came for, shall we?’

Taemar and his squad found a couple of adepts manning the cogitation banks, and he gunned them down perfunctorily, barely raising his bolter before holstering it again.

Once he found the correct terminal, he took out Valthex’s device. As with so much of Valthex’s technology, it had a touch of sorcery about it, technical genius enhanced by other techniques that Valthex had learned in the Maelstrom. When Taemar attached the device to the cogitator bank, the connecting wires seemed to guide his hand, hungrily seeking out the correct sockets.

Taemar pressed the helpfully bright red sigil on Valthex’s device. A flicker of static passed across every screen in the room, then nothing.

‘Lower the block,’ he said.

Rioss tapped on his auspex, and nodded.

Taemar looked again at the screens, and smiled. Valthex’s art was subtle. To those who received relay messages via Outstation One, nothing would have changed. In reality, everything had. A blind spot had been created within the early warning system, a filter within communications.

He checked his chronometer. They were ahead of schedule. A shame that he had no means of informing Lord Blackheart that his part in the scheme had been completed with such efficiency. Never mind, it was done and that was what counted.

‘Objective completed, signal for extraction,’ he ordered.

‘The sea in the sky, the sea in the sky,’ muttered Veteran Sergeant Kretschman of the Cadian 301st as he tried to concentrate on the ground beneath his feet rather than the distant ground above his head.

He knew that he was talking to himself aloud, rambling in a way that others might consider evidence of mental disorder, and could see the sideways looks people were giving him as they jostled past on the busy streets of Eridano, but he didn’t care. His mantra was very useful to him as a coping mechanism to calm himself and deal with certain unfortunate realities of his current environment. Besides, he had nearly died in the service of the Emperor. These Hollow Worlders, these Lastrati, sheltered by their metal skies, could stuff their sideways glances.

The months of recovery were a blur to him now, and the continents above were not helping him regain focus. He had been almost dead when that scout, Kulbard, had pulled him out of a pile of bodies on Tarff. The battle there was over and the 301st had moved on, to the Hollow Worlds, where the regiment was regrouping in preparation for their next deployment.

His journey had brought him to the outer Hollow World of Laghast, and from there to Eridano, a city spread across several islands of an archipelago, the natural land supplemented by artificial areas built on stilts. The looming buildings blocked some of that sinister sky, while narrow canals ran between, rackety footbridges overhanging them at many different levels. Kretschman pushed through crowded streets, elbowing sullen, broken-faced civilians out of the way as he searched for the streets he needed, consulting the hand-drawn map he had been given by Kulbard.

Those were the clear parts of his recovery, Kulbard finding him in infirmaries and barracks as he travelled alone, helping him make his way back.

Eventually, Kretschman came to a long, narrow street overlooked by towering habs, leading out to where he needed to be. After a long walk, he reached an Imperial Guard barracks surrounded by high rockcrete walls topped with razor wire. He banged on the door, and was greeted by a familiar face poking out from the small hatch that opened in the plasteel.

‘We thought you were dead,’ said Sergeant Rothke. His tone suggested he didn’t think of Kretschman’s survival as being particularly negative or positive, simply a surprise.

‘Really?’ said Kretschman, sliding the stamped parchment indicating he was ready for duty through the hatch. Rothke’s face disappeared as he checked the documents.

‘You’ve been gone for months,’ said Rothke, when his face reappeared.

Months? Had it really been that long? For Kretschman, so much of the end of that campaign, even before his injury, was a blur. Even now there was so little he recalled.

‘Well, here I am,’ was the best response he could manage. ‘I’m fit for duty now.’

‘Best report straight to the commanding officer,’ said Rothke, unbolting the heavy door and waving Kretschman in. ‘Officers’ quarters and command are in the round building. Can’t miss it.’

‘You can take me with you, sergeant,’ said a voice behind them. ‘I need to speak to the most senior officer in your regiment.’

Kretschman turned to see a short man. He was balding, somewhere in middle age and wore the same grey coveralls that most of the workers on Laghast seemed to wear. Kretschman had never even heard him approach and, judging by Rothke’s startled reaction, neither had the man ostensibly guarding the entrance gate.

‘And what the hell do you want?’ demanded Rothke, moving to block the civilian’s path.

The civilian sighed and raised a hand, gesturing to indicate he was going to slowly remove something from his jacket.

Rothke, lasrifle in hand, nodded for the civilian to show whatever papers he held.

The civilian removed something small and round from his inside pocket, raised it in the general direction of Rothke and Kretschman. An image of a red seal emblazoned with a stylised letter ‘I’ appeared in the air between them.

‘I am Inquisitor Pranix of the Ordo Malleus,’ said the man. ‘What I want, and what I am going to get, is complete authority over your entire regiment, beginning right now. The Hollow Worlds of Lastrati are under grave threat.’

Three

The Tower of Astropathy dominated the skyline of the mountain city of Carapel, one of the southernmost cities on Laghast. The tallest building within the entirety of the Hollow Worlds, its crooked spire seemed to wind its way towards the artificial star above, even though the astropathic choir who resided within the dome at the top of the tower had their minds turned in the opposite direction, out of the system and towards sacred Terra.

The tower stretched from the base of the mountains, deep in the darkness, up through the platform city built between the peaks, and then higher still, above the very peaks of the mountains. Its structure twisted between the walkways and platforms of Carapel in such a way as to cast shadows on buildings that were streets away. Occasionally a slate would fall from the tower’s higher reaches and embed itself in the head or shoulder of some unfortunate passer-by, or else fall through the gaps in the walkways and into the darkness below.

All astropaths within the Hollow Worlds resided within the tower; such was the distance between the Hollow Worlds and the nearest astropathic relay, and the distorting effects of the Siren Clouds, that it took the collective power of a large astropathic choir to maintain contact with the Imperium.

They worked in shifts, ensuring that the choir remained at full power. Robed and blind, the astropaths shuffled from their meagre quarters to the chamber which contained the choir, only pausing for meals and other basic biological functions. Theirs was an austere, cloistered life, but a vital one, and they were supported by countless servants and slaves.

The servants were regularly screened for signs of heresy or mental breakdown, so it should have been impossible for three of them to commit the ultimate act of betrayal. Walking with heads bowed, as the servants of the astropaths always did, they met in one of the uppermost chambers of the tower as the silent bell tolled.

They did not speak or acknowledge each other as they threw their heads back and were consumed from within, the small mechanical creatures within their bodies eating their way out of their brainwashed carriers, consuming flesh and clothing alike before scurrying across the floor, walls and ceiling, chewing their way into the tower itself. Touched by Chaos, these tiny creatures recycled base metal chewed up by their jaws, using it to reproduce, each miniscule metal insect growing before splitting into two, eating everything in its path. By the time they had dug into the superstructure of the tower, they were legion, even though their lives were short and chewing into the girders that made up the skeleton of the tower caused more of them to shatter than could be built to replace them. Before the last one ceased to function, these cursed, artificial insects had fatally undermined the stability of the tower.

As that part of the tower collapsed it created an absence between the floors above and below, one that was immediately filled as gravity took hold and the levels fell downwards, crumpling and crashing into the lower ones.

As a shower of brick dust and rubble was thrown upwards, the higher levels of the structure veered, the twisted shape of the tower and its elaborate structure causing the top to fall sideways. Loose slates and statues tumbling off it crashed down onto the streets and buildings in its shadow.

It fell like an executioner’s blade, smashing into the elaborate structure that connected the city of Carapel to its supporting peaks. As the tower slid into the darkness at the base of the mountains, so too its weight began to drag down most of the city around it, causing beams to break and further buildings to collapse.

Within minutes not just the Tower of Astropathy but most of the city surrounding it had descended, fatally, into the abyss, leaving only a scattering of buildings and platforms still connected to the mountains, now isolated from each other. Most of the population, tens of thousands of souls, lay dead, far, far below, crushed in an avalanche of what had recently been one of Laghast’s busiest cities.

Colonel Ruthger, commanding officer of the Cadian 301st was in many ways the archetypal Cadian officer, a born survivor hardened by years of war. He was the kind of man Veteran Sergeant Kretschman deeply admired, at least partially because Ruthger mirrored how Kretschman liked to see himself. It was not in the character of a man like Ruthger to be rattled by an outsider trying to impose their authority on him, even when that outsider was a member of the Emperor’s Most Holy Inquisition.

Following Rothke’s directions, Pranix and Kretschman – who the inquisitor had insisted accompany him – found their way to the officers’ mess, which lay behind a heavy black door emblazoned with a silver skull and an inspiring quote about leadership. The leering skull was not an uncommon motif in the Imperium, but here its meaning was clear – the lower ranks should not pass this threshold unless their errand was worth risking decapitation for.

Inquisitor Pranix didn’t break his stride as he opened the door and walked into the room beyond.

The colonel was sitting alone on a black velvet-covered chair, a goblet of amasec in one hand and a sheaf of official parchments in the other. He looked up from his reading as Pranix strode into the room, but did not speak or offer any further reaction as the inquisitor dropped into the chair opposite him.

Kretschman, unsure of the politic thing to do in such circumstances, stood to the side, standing to attention and offering the colonel a sharp salute. There he stayed, awaiting further orders.

The colonel nodded to Kretschman, but kept his eyes on Pranix as the inquisitor reeled off an introduction similar to the one he had given to Rothke and Kretschman at the gate. He had unbuttoned the top of his coveralls, the seam of which opened out into sharply cut lapels; on one was fastened a small silver badge shaped like a letter ‘I’. When Pranix referred to himself as an inquisitor, Ruthger’s eyes flicked to the badge briefly, as if checking its authenticity, but otherwise he listened to Pranix intently.

Kretschman had seen inquisitors before, on the battlefield and communing with senior officers. He knew that Ruthger had encountered them too. He suspected that, in spite of his lack of obvious reaction, Ruthger was taken aback by Pranix’s appearance – most inquisitors in the field were towering figures dressed in elaborate robes, wielding ornate personalised weaponry and laden with symbols of office and mystical paraphernalia. On some level the common Guardsmen were not supposed to know of or acknowledge the Inquisition and its work, but the inquisitors hardly conducted themselves discreetly.

Pranix, on the other hand, only resembled an inquisitor in terms of his formidable self-possession. Ruthger was probably having the same doubts as Kretschman. In spite of the badges of identification, was this really an inquisitor or just some lunatic?

Ruthger sipped his amasec, then placed the goblet on the table. When he spoke it was with deferential calm. ‘While you are entirely within your rights to take command, my lord, it would be… helpful to the transition of command to know the nature of the crisis we face.’

Pranix removed a vial from an inner pocket and tossed it across the table to a surprised colonel, who caught it out of the air and held it up to the light.

Kretschman couldn’t resist glancing down at the vial. It appeared to contain some kind of grey insect.

Colonel Ruthger caught Kretschman looking, and offered him the vial.

‘Sergeant,’ said Ruthger. ‘Have you ever seen anything like this? And for the Emperor’s sake, stand at ease. It’s making my neck stiffen just watching you there.’

Kretschman nodded, slackening his shoulders, and took the vial from his commanding officer. It was, as he thought at first glance, an insect. Small, like a beetle, with a strange metallic shell. Its body was spattered with some kind of blackened crust. There were only a couple of reasons why such a creature would be considered a threat.

‘Not seen this one before, sir,’ he said to the colonel, then turned to Pranix. ‘Is it an infection carrier, my lord?’

Pranix looked impressed. ‘A clever thought, sergeant, but not quite. We’re dealing with something worse than swamp fever. Look closer at the shell. What do you see on the beetle’s back?’

Kretschman squinted at the beetle. It was hard to make out, but there appeared to be irregular but precise symbols carved into the beetle’s shell. Something about them made Kretschman’s retinas feel hot, and he blinked a couple of times.

‘It’s writing of some kind,’ he said. ‘Hard to make out exactly what it says, though…’

Kretschman looked harder, and was surprised to find the vial gone from his hand – Pranix had snatched it away so quickly he was left staring at his own fingertips.

‘Best not to look too closely,’ said Pranix, pocketing the vial once more. ‘Those symbols represent the foulest heresy. I could give you a lens to see them in perfect detail, but the reaction wouldn’t be pleasant and I doubt the colonel would appreciate you crying blood into his amasec.’

‘A… heretical insect, then,’ said the colonel, visibly exasperated. ‘But what’s it for, my lord?’

Pranix leaned forwards. Kretschman was still standing there, but the colonel and the inquisitor – Kretschman was finding it harder and harder to doubt Pranix’s credentials – had their attention locked on each other, and seemed to have forgotten he existed.

‘I extracted that insect from the brain of a filing clerk in the long library in Carapel,’ said Pranix. ‘His fellow clerks had beaten him to death to stop him from eating their overseer’s face. Before he died, he was speaking in an unknown tongue, and the words haunted the nightmares of everyone who heard them for weeks afterwards. Two witnesses had to be executed for heretical outpourings after the incident.’

‘That’s one incident,’ said Ruthger. ‘Disturbing, but insanity amongst the menials is not unknown. Surely not enough to warrant the Inquisition’s attention.’

‘It does when there is a pattern. The Inquisition watches all, and I am always alert to this kind of pattern,’ said Pranix. ‘As you say, insanity and butchery are not uncommon, and nothing a few executions won’t resolve. But when there are many, many incidents of this kind, over months, spreading across a specific area… Even though no one of significance was killed, the phenomenon was visible, and the source clear.’

‘The source?’ asked Ruthger.

‘The first incidents were in areas near to the Hellward Gate, mainly the port cities on the nearest shoreline,’ said Pranix. ‘But since then they have spread, less concentrated geographically but much further afield, across all of Laghast. Everywhere, attacks by otherwise innocuous subjects of the Emperor. And, where I have had the chance to requisition the bodies, these insects were present in a high percentage of incidents, buried deep in the brain.’

‘An infection, corrupting the mind,’ said Ruthger. ‘Introduced from off-world, slowly spreading. But only on Laghast, you say, not further into the Hollow Worlds?’

‘No,’ said Pranix. ‘It seems a curious limitation, something to do with the Archways. I myself had a dozen samples of similar insects which I intended to take to the Adeptus Mechanicus on Kerresh to obtain their opinion, but having passed through the Archway I found that there was nothing but dust in my sample cases. These creatures go wherever the carrier goes, but they cannot pass through the Archways.’

‘But what’s the purpose, if the carriers don’t attack anything of importance?’ asked Ruthger.

Kretschman had been wondering the same thing. The insects seemed to do nothing more than the kind of damage caused by hive riots and slum plagues in any given year.

‘I don’t think these attacks were intentional,’ said Pranix. ‘I think they were malfunctions. I cannot determine the exact nature of these insects, nor their purpose, but they are organic creatures augmented with technology and contaminated with the vilest heresy. They are undetectable, even by a trained psyker like myself. That they should be created for such random carnage is unlikely – I believe the intent was for the carriers to perform some specific act with far greater impact. I believe that what we have seen so far is the result of a small number of failures, where the human subjects have broken down due to the touch of heresy.’

‘How many of these failures have already occurred?’ asked Ruthger.

‘Somewhere between two and three hundred,’ said Pranix. ‘Although I cannot be entirely sure.’

‘And what percentage of the total infected would you consider those failures to be?’ asked Ruthger.

‘I cannot imagine more than three per cent,’ said Pranix.

Ruthger had nothing to add, and sat back in his seat.

‘So you see, colonel,’ said Pranix. ‘We may have thousands of unwitting agents of heresy within our midst, and no idea of who sent them or when they might be activated.’

‘What do you need from us?’ asked Ruthger.

Pranix was about to answer him when someone tried to kill them all.

The assassins came in through the rear entrance to the officers’ mess, via the kitchens. Though dressed as lowly workers and servants, they acted ruthlessly and efficiently, raising their weapons and aiming straight at the colonel.

Kretschman reached for his lasrifle the moment the door was kicked open, but felt himself being roughly pushed aside as the inquisitor moved forwards to kick the colonel’s chair over, causing the commanding officer to tip backwards onto the ground.

Before Kretschman had brought his weapon back up, the inquisitor had taken down their attackers with three tight bursts from a laspistol. The assassins fell to the floor, dead before they could even fire a shot.

‘Apologies, colonel,’ said Pranix. ‘There was no time for a formal plan. It was lucky I was carrying a weapon. I don’t usually travel armed, it tends to be conspicuous.’

Kretschman, moving to help the colonel off the floor, suspected that if the inquisitor didn’t bother going armed most of the time, it was because he didn’t need to be.

‘It’s started,’ said Pranix redundantly. ‘No doubt the authorities on this world will already be under attack. We need to move to take control of the city, starting with a suitable hub to be our base of operations.’

The colonel took this in his stride.

‘I believe, lord inquisitor,’ he said, brushing himself down, ‘that I know a place.’

Dumas Cheng had been system governor of the Hollow Worlds of Lastrati for over 150 years, since the death of the previous incumbent. As was ancient tradition, he had been elected to the role by his fellow planetary vice governors following a mere seventeen years governing Plini. His tentative appointment had been approved by the appropriate Imperial authorities via astropathic message, and he had been the Emperor’s voice within the Hollow Worlds for a century and a half since.

It was a position of unquestioned authority, and Cheng’s rule had been a successful one. Although no system in the Imperium was ever free from strife, rebellion, heresy and attempted invasion, all of these threats had occurred in a predictable fashion and been crushed with efficient brutality. A high state of security and regular purges had ensured that Cheng’s reign had been a largely peaceable one, and that the import and export of people and resources that was the Hollow Worlds’ lifeblood continued unimpeded.

While the great machine of war was fed at a satisfactory rate, the wider Imperium saw no reason to interfere in Cheng’s administration. The Hollow Worlds were secure and efficient, a barrier between the wilds of the Maelstrom Zone and some of the Imperium’s safest worlds.

It was a fortress system, and its walls were strong.

Aided by countless rejuvenat treatments, Cheng had kept in good health, and rose early every day to go about his duties. As his worlds were ruled in orderly fashion, so he lived an orderly routine.

He was unaccustomed to being woken in the early hours of the morning by the sounds of voices raised in panic.

The throne world of Ressial was the administrative, if not geographic, centre of the Hollow Worlds. The interior of the world was dominated by the Onyx Palace, a vast structure of lavish halls and twisted spires that was clearly visible from any point in the world, at the centre of which a cavernous throne room held a throne so resplendent it could blind the unwary.

The palace had been built by ten thousand slaves over a dozen centuries, and it lay completely empty, kept immaculate by a legion of servitors for the impossible day when the Emperor might choose to visit the Hollow Worlds and take His seat upon that sparkling throne.

At the edge of the Onyx Palace’s deserted estates lay the Gatehouse, an aquila-festooned ziggurat that, compared to the Onyx Palace itself, was merely obscenely ostentatious. Each step of the ziggurat was lined with spikes, upon which were placed the skulls of traitors and invaders who had tried to disrupt the peace of the Hollow Worlds.

The Gatehouse was the system governor’s residence, and it was there he was woken in the very early hours. His underlings ushered him through the ziggurat’s catacombs to a central communication room filled with scribes and serfs, monitoring cogitators and scratching their findings onto vellum.

Cheng took to the lacquered throne at the centre of the room and plugged himself in, attaching the required tubes, including the nutrient pipe into the side of his neck. As system governor he would not move until any crisis was resolved. That was his duty and his honour, although he silently wished he had been given the chance to eat some solid food first.

As nutrients and stimulants woke his body, Cheng accepted a sheaf of vellum from a robed servant, and quickly scanned the reports. They spanned a mere two hours, and were fragmentary at best, but they described a disturbing series of events all across Laghast.

The fall of the Astropathic Tower. Attacks and assassinations. A Lastrati Astra Militarum regiment besieged in their barracks, while the vice governors of three worlds were missing, presumed dead. Water had been poisoned, cities were ablaze.

Disturbingly, in the short time these events had occurred the reports were becoming more, not less, fragmented, as if something had infected the Hollow Worlds’ communications.

Now that he was connected to the control throne, Cheng could feel it. A hiss, a sinister build of static where there should have been a relentless stream of signals and communications at the edge of his awareness. It was like an absence, a lack of information, but at the same time it felt like something more substantial and malignant. Trying to feel the nature of the interference, Cheng felt an itch behind his eyeballs, a growing sense of nausea.

Reluctantly, he disconnected the cable that linked him into the comms network.

The destruction of the Astropathic Tower meant that no distress signal could be sent out of the Hollow Worlds. Communications within the system were disrupted.

‘Orbital defences?’ the system governor asked. The pause was damning enough. Contact lost.

Dumas Cheng sat back in his control throne. Over his long reign, he hoped that his leadership had instilled some values and resilience in his subjects, that they would prove capable of acting as he would wish even without his specific order.

Now, he was relying on that legacy. The Hollow Worlds depended on the ability of its inhabitants to pull together and resist these attacks, wherever they came from.

Aboard the Might of Huron, it fell to Garreon to inform his lord that the time was at hand. Lord Huron’s Terminator bodyguards parted as the Corpsemaster approached the doors to the Tyrant’s personal quarters, a rare privilege denied to nearly all.

Those quarters were in darkness, as they nearly always were, but Garreon could see the outline of Huron’s throne illuminated by the light pouring in from the door. Blackheart had no need for sleep, and sitting on that throne, adepts under Garreon or Valthex’s command working to maintain his augmetics, was the nearest he came to rest.

The throne was empty. There was little ornamentation in the room. A row of shattered Space Marine helmets and a couple of inhuman skulls were attached to one wall, evidence of former conquests, though Huron’s insatiable lust for power meant he never dwelled on old glories. On the opposite side of the room to these trophies sat a large chest, too large even for Garreon to lift alone, made of unknown alien wood and locked with a padlock of dark, shimmering metal. Even in the shadows that chest seemed to drink in the darkness. Garreon did not know what it contained exactly, but he had seen Huron occasionally open it to consult ancient books bound in scarred hide, or produce a vial of tar-like, unknown liquid. Whatever secrets lay in there were blasphemies beyond even Garreon.

A porthole dominated the chamber, and it was there Huron Blackheart stood, looking out into space. Framed in starlight he was a giant, even compared to his Red Corsairs, his silhouette lopsided due to the mass of the Tyrant’s Claw. Huron did not turn around as Garreon entered the room, but the Corpsemaster could see the red glow of Huron’s augmetic eye reflected in the porthole, watching his reflection.

‘It is time,’ said Huron Blackheart.

‘Yes, my lord,’ said Garreon. ‘Our sleepers will have awoken and done their work. Taemar has had plentiful time to introduce Valthex’s scrapcode. The Hollow Worlds are open to us.’

‘Yet we have no way of being certain of that,’ said Huron, turning to face Garreon. In the darkness his organic eye was invisible, but his augmetic eye flared dangerously.

‘The insektiles are reliable, my lord, I am certain of it,’ said Garreon, fully aware that any sign of doubt would soon see the Tyrant’s Claw locked around his throat. ‘Taemar’s part is entirely within his capabilities.’

If there was any failure, and should the Red Corsairs survive, Garreon was determined that the blame should fall squarely on Taemar. If he survived, the Corpsemaster would sooner face the Hollow Worlds’ fully active defences than the vengeance of his lord.

‘Then we shall make our move,’ spat Huron, marching towards the door. ‘I shall take the bridge.’

Across the silent fleet, noise and light. Engines flared into life, weapons systems activated, and the entire fleet began to move forwards with purpose. On ships large and small, the lowliest slaves hauled mechanisms into place, while those who had offered lifelong fealty to the Corsairs and earned a brand of status moved into battle stations and manned navigation posts.

Huron Blackheart stood on the bridge, Garreon and Valthex flanking him. Around them moved a bustle of Red Corsairs and human crew operating equipment and monitoring auspexes, and the bridge roared with noise as orders and reports were shouted back and forth.

But when Huron issued an order, all went silent, not just on the flagship but across the fleet, his words voxed from ship to ship.

‘Set a course for Laghast,’ he said, his voice a guttural rattle. ‘Man all stations, open our forward sensors to the entire fleet.’

Emerging from the warp too near to the Siren Clouds was suicide, but the slow drift of the fleet had brought them within close range of the Hollow Worlds. As they closed in on the target, approaching the ancient batteries of weaponry that guarded the Hellward Gate on Laghast, those aboard the Red Corsairs fleet who still breathed, whether they be Traitor Marine or human slave, held that breath, and listened to the vox piped into every level of every ship.

If there was an offensive response to the fleet, an alarm would ring out, first a tentative ping and then, once the nature of the response was confirmed, the klaxon that called all ships to battle. In those first seconds of engagement, Huron Blackheart would decide whether to fight or take flight, and their fates would be sealed.

Huron did not move, although the Tyrant’s Claw closed tight. Beside him, Valthex was impassive, while Garreon simply licked his dry lips with a blackened tongue. The few humans on the bridge knew better than to show any reaction unless demanded by the Tyrant, while the servitors welded into their stations had no reaction to give.

Every single Red Corsair, and all the humans required to man a weapon or station, knew from weeks of preparation what they would face. The sensor arrays hidden in a string of rocky planetoids on the approach to the Hollow Worlds. The void shield satellites that, when automatically deployed, would cut any approaching ship to pieces with criss-crossing force fields. The disruptor fields and mines that would scatter if they were detected, destroying the fleet with countless small explosions. The automated laser batteries floating between the planetoids.

After all that, should any surviving ships get within range of Laghast, the missile silos that ringed the Hellward Dock would finish off any stragglers.

The fleet entered the kill zone, passing through where the first sensor arrays were placed. On every bridge of every ship, officers and slaves waited to activate weapons, to defend themselves, to take evasive manoeuvres.

The alert never came. The ships moved on, approaching the Hollow Worlds.

Flickering forward sensors showed the world of Laghast, an algae-encrusted sphere scarred with the great blister that was the Hellward Gate, the entrance to the Hollow Worlds. The facilities of the gate stretched far across the planet’s surface, with a grey sprawl of landing areas where shuttles could descend from the orbital dock that hung over Laghast.

Nearby was Plini, with its chained satellite, and behind both those worlds lay the impassable, looming mass of the Siren Clouds, which registered on all sensors as a solid wall cutting through space itself.

Huron did not stop to register the moment, to congratulate them or acknowledge the danger that had passed. Instead his eyes were hungrily locked on the vision of Laghast before him, and what it represented.

‘Now,’ he said, each word bloated with fierce desire. ‘We truly begin.’

Four

The small, city-sized complex on the outer surface of Laghast known as the Hellward Gate was largely windowless. On a world without atmosphere, it was easier to construct solid, sightless buildings than to include sealed windows that looked either out onto Laghast’s barren surface, or up into empty space. Besides, in the latter case all true subjects of the Emperor knew from birth that there was nothing in space except fearful, alien forces. In such a universe, who wished to look out into the malignant stars? It was unwise to look up, so why provide temptation?

While there was a small Lastrati Guard presence in a barracks to the west of the complex, ready for the unlikely case of a ground incursion, the full-time security of the Hellward Gate was controlled by the Jandarme, the Hollow Worlds’ permanent military force. Reporting through the system governor’s hierarchy, the Jandarme were responsible for the defence of the system as well as the quelling of internal unrest and the exercise of violent force for the purposes of imposing the system governor’s justice upon the Lastrati peoples.

Corporal Tusc was one such Jandarme, who had previously been assigned to the streets of Eridano. Since his assignment to the Hellward Gate he had reported to duty and manned a terminal monitoring vox-channels and sensor arrays, waiting for an alert from either the remote defences or a live sentry.

That all had been quiet for a number of hours did not alarm Tusc, or any of his fellow Jandarme in the control centre at the heart of the Hellward Gate, one iota. No ships were scheduled to arrive. Nothing got past the automated defences. Comms with the interior were down, a mass of fuzz and static, as was vox contact with the orbital dock, but this was not remotely unusual – vox-comms were inherently unreliable, especially in a facility adjacent to the effects of the Siren Clouds.

What mattered was the all-clear ping from the sensor arrays, and that continued to chime every minute.

All clear.

Behind Tusc there was a change of duty officer. Lieutenant Kardon was taking the station. Good. Kardon ran a tight shift, but wasn’t the kind of officer to impose pointless rigour for the sake of it, providing the job got done. The rest of Tusc’s shift would likely pass without needless drills.

‘All clear, corporal?’ said Kardon.

Tusc’s internal clock, finely honed over the last year, told him it had been 53 seconds since the last ping.

‘I’ll check, lieutenant,’ Tusc said with a deep frown.

Ping.

‘All clear, lieutenant,’ said Tusc.

‘Glad to hear it, corporal,’ said Kardon. ‘Eyes to your station, please.’

There was a murmur of stifled laughter from around the room.

‘That goes for the rest of you,’ said Kardon, not without humour.

As Tusc turned his attention back to his station, the vox burst into life. What came through was a chorus of obscenity, a thousand voices screaming blasphemous filth into his ears. The chanting made Tusc’s ears ring painfully, like seeping, bitter cold cutting into his ear canals. And through it all, a single message, a single subtext – that they were filth, they were nothing, they were weak, and they would all soon die.

The message came through on Tusc’s monitoring station, but as he tore away his headset he realised it was everywhere, coming out of every speaker and vox-grille in the room. He saw someone at a nearby station collapse forwards, eyes rolling up into his skull as he lost consciousness, and heard someone else vomit. Lieutenant Kardon was on her feet, staring from side to side, as if the owners of the taunting voices were somehow in the room with them.

Tusc knew, as they all knew, that this was no simple act of sabotage. The voices were entirely serious.

Then, silence, everyone in the control centre looking at each other.

Tusc touched one finger to a wet patch beneath his left ear. Blood, dripping from his eardrums.

‘What the hell was that?’ asked Lieutenant Kardon, leaving the other part of the question unsaid: What next?

The message broadcast to the enemy was being fed back into the Tyrant’s own fleet, and as the crew members and Red Corsairs contributed their own oaths to the tirade, so they were fed back into the outgoing signal, a self-sustaining loop of malice, blasted at the enemy below.

Garreon barely raised his voice, instead taking pleasure in the ferocity of his fellow Corsairs, and the terror their oaths would cause. He remained at his lord’s shoulder on the bridge, watching as the main viewscreen showed the Hellward Gate on the outer surface of Laghast. They were closing in now, and the larger ships of the fleet would be within targeting range. On cue, reticules began to appear over parts of the Hellward Gate complex on the auspex, suggesting possible targets.

The Corsairs’ tirade ended suddenly, Huron cutting it short with a gesture, and the shipmasters relayed his order. Huron, with no little help from Garreon, had instilled fear and discipline into this rowdy warband, and Garreon took pride at how fast the Corsairs silenced themselves when ordered to.

Huron took a second’s silence as the vox-channels were adjusted, then spoke again, this time to his fleet rather than his enemy.

‘All ships,’ growled Huron. ‘Sight targets and say aye.’

On the viewscreen, targeting reticules appeared over the main buildings of the Hellward Gate. As the other ships of the fleet found their target, repeated cries of ‘Aye!’ came over the vox.

Doubtless the Imperial lackeys below would have realised that their systems had been fooled, and would be running back and forth trying to regain control of them manually.

‘Let them think they can live,’ Huron whispered, so quietly only Garreon could hear it. ‘Let them have that brief hope.’ Then he chuckled, a guttural, hideous sound.

‘It will do them no good,’ Garreon said quietly in reply.

‘On my order, fire,’ said Huron, louder now, the Tyrant’s Claw raised high.

‘Fire!’ he shouted, his claw swinging down like a wrecking ball, as if he could crush the Imperial forces below.

The onslaught began. The viewscreen was streaked with trails as missiles and shells rained down upon the outer surface of Laghast, targeting specific and sensitive areas.

The missile and laser silos on the surface were obliterated, causing chain reactions beneath the surface of Laghast that shook the entire Hellward Gate. The dome of the Lastrati Guard barracks was also destroyed. Fire consumed large parts of the complex.

As the missiles rained down, one area was spared the devastating assault, a static point in the carnage: the centre, the dome covering the zero-gravity corridor that led from the skin of Laghast to its interior. Access to the corridor needed to be preserved, and the effect of the surrounding bombardment and the untouched centre was that of a halo of destruction scorched into the surface of Laghast.

The first explosion on the surface of Laghast was felt in the Hellward Gate’s control centre. The strike did not register on any of the systems, but Tusc felt it – the sudden jerking motion that moved through the deck beneath his feet, and swept up his body as a tremor. There were shouts of shock and terror from nearby, mostly drowned out by the roar of multiple explosions, loud but also distant. A scattering of dust and algae crumbled down from the ceiling above, clouding the air.

The second and third explosions hit before Tusc could even steady himself from the first.

Tusc swung around in his chair to request orders from the lieutenant in charge.

‘Corporal, report,’ snapped Lieutenant Kardon, as the entire room continued to be shaken by an irregular series of jolts. They were near, but nothing seemed to be striking the control centre itself.

‘Nothing, lieutenant,’ Tusc replied, checking all the readouts before him. It was impossible – something was clearly happening, but it wasn’t registering on any scanner or system. They were at the centre of information for the Hellward Gate, the Hollow Worlds’ eyes out into space, and while the room was shaking from impact after impact they did not even know the cause. Which could only mean…

‘Our systems have been fooled,’ snapped Kardon. ‘Do we have vox?’

‘Still down,’ said a voice nearby. It occurred to Tusc that the vox failure of the last few hours might not be a normal fault after all.

‘Sound the alert,’ said Kardon. ‘I don’t care if we don’t have vox, just ring the damn alarm, and if necessary get out there and shout it. All personnel to stations. I want everyone atmosphere-suited within ten minutes.’

As she issued the orders, Kardon was already beginning to suit up herself, pulling a pressure suit over her pressed green uniform.

‘Tell everyone we’re under attack from unknown hostiles,’ she snapped.

‘My Lord Huron,’ one of the bridge crew reported. ‘The Crimson Flask and the Shrieking Spear have been destroyed.’

‘A minor loss in favour of a greater cause,’ spat Huron. ‘Garreon will ensure nothing is wasted.’

‘My lord,’ said Garreon, nodding at the compliment, even though Huron Blackheart had his back turned to him. When this battle was over, Garreon’s underlings would scour the wreckage for injured and dead Red Corsairs. Even in death they could be of use to the Corpsemaster’s experiments.

As for the mortals, it was their only purpose to die in service to Lord Huron.

‘Cease fire,’ ordered Huron. The viewscreen on the bridge was blurred by the smoke obscuring the Hellward Gate, but there was no sign of heavy retaliation, or any fire from the ground.

‘All ships prepare to dock then hold,’ barked Huron Blackheart, turning to leave the bridge. ‘I want all landers and pods launched before we take the orbital dock.’

As they marched to the landers Huron turned to Garreon and Valthex, who were in step behind him.

‘We’ll take it all at once,’ snarled Huron, clenching the Tyrant’s Claw. ‘In the sky or on the ground, we’ll take it all.’

The orbital dock above Laghast was a sprawl of metal, branching out into a series of beams and arms, spaced apart to allow ships to dock, locking into place and connecting to the dock via boarding tubes. While landers were used to transport people and cargo down to the planet’s surface, standard maintenance equipment and supplies were loaded and unloaded on the orbital dock as part of the rituals of maintenance and re-fuelling.

Workmaster Strank was shouting at two servitors to prevent a collision between two large cargo containers, when the entire dock was shaken by an explosion. The loading tube shook so severely that a rent emerged in the wall, a gap opening out into space, and air began to leak out.

At this point Strank’s training kicked in and he slammed the helmet of his atmosphere suit down over his head. It sealed with a low hiss, and he began breathing stale air. With his other hand he grabbed hold of one of the handrails that ran down the length of the loading tube.

Strank looked down the tube, and saw that the breach had grown wider.

Hand over hand, he threw himself up the tube towards the main arm of the dock. The airlocks had automatically slammed shut, and when Strank reached the airlock he had to punch a security code into the control panel to open it.

He tumbled out of the airlock into a wide corridor ribbed with the girders that formed the frame of this arm of the dock. He needed to get to the central hub of the dock, which was robust enough to survive any impact.

The dock was shaken by further explosions as Strank ran. What he found as he entered the central hub was an ongoing bloodbath. The great open spaces of the central hub were overrun with heavily armoured giants, spreading throughout the dock and gunning down anything in their path.

The attackers’ armour was blood red and emblazoned with skulls and other grotesque symbols. Some had simple helmets, domed with grilles and eye-lenses, while others had horns or other formations protruding from their heads. They were humanoid, but also monsters, moving faster than humans, wielding huge weaponry that spat death.

Strank was so frozen in shock he didn’t see where the shot that killed him came from; he just felt a searing pain in his chest, and looked down to see a scorch mark on his uniform and blood seeping through. Then the pain was replaced by a spreading numbness.

He looked up again, but all he could see was the terrifying giants still advancing, destroying everything in their path. Strank’s last thought was that the orbital dock was as doomed as he was.

Five

Rotaka and his squad were in a drop pod falling towards the surface of Laghast. Malinko, a flamer-wielding brute in scorch-blackened armour, expressed his understanding of the situation to his commander.

‘Do I understand this correctly?’ Malinko said, leaning forwards, his finger jabbing at Rotaka. ‘You have volunteered us to take part in the first strike against an unknown number of enemies in an uncertain situation, probably a boxed-in kill zone, with the forces of an entire planetary system set against us?’

‘Yes,’ said Rotaka.

Malinko withdrew his accusative finger, and patted his gauntleted fist against the chestplate of his power armour in a parody of emotion.

‘Truly, this is a kind gift, captain,’ he said. ‘Is it the anniversary of my birth, or my ascension to these hallowed ranks? Either way, the rest of you should feel fortunate that I am allowing you to share this with me.’

‘You’re too kind,’ said Wuhrsk, voice level as ever. His armour stripped of ornamentation, Wuhrsk rarely raised his voice, preferring the silence as he did the shadows. ‘I hope to repay you with equal generosity some day.’

Verbin laughed, a deep hollow sound. A brute who liked to get his hands dirty, his armour was stained with dried blood, and he strained his fingers in his gauntlets as he chuckled.

‘It is no laughing matter,’ said Hulpin, not looking up from his chainfists as he gave them a final inspection. ‘What we do we do for the gods. It is ritual, not leisure.’

Pious as ever, thought Rotaka. Both Verbin and Malinko seemed on the verge of replying to Hulpin, but they were cut off by the sudden, massive jolt of the pod hitting the ground. Rotaka felt the full body shock wave pass through him, then reached out and pulled the pod’s release handle, the lever twisting down in his hand. As the pod opened there was a low hiss, and light seeped into the dark pod around the edges of the hatch.

Emerging onto the outer surface of Laghast, Rotaka could not miss their target. The Hellward Dock was a metallic scar across the land, a sprawling space port built on an uninhabitable, algae-covered waste. The outer surface of Laghast was completely airless, so the facility was airlocked, and most of it was made up of landing pads and blocky, anonymous buildings. Without a nearby sun the surface of Laghast was illuminated only by starlight, and the artificial light from the Hellward Dock blazed out across the dusty plains on which the Red Corsairs drop pods were landing. Many of the buildings were already wrecked by the assault from Huron’s fleet, flame bursting out then guttering away with the lack of air. Rotaka could see the skeletal remains of ground defences silhouetted against the flames, the barrels of burned-out gun emplacements black against the raging fires.

All around, drop pods continued to land, and above their heads landers and shuttles could be seen drifting downwards. Rotaka saw Becaro leading his squad out of a drop pod, his bolter glowing green with the ‘blessing’ coming from his hands. Looking ahead, Rotaka could see a great dome covered the Pit, the great shaft into the centre of Laghast, their target.

‘We know where we’re going,’ said Rotaka over the vox, pointing towards the dome. ‘Let’s get there before Becaro.’

A mortar exploded nearby. Ahead, atmosphere-suited humans were emerging from a scorched bunker, firing on the advancing Space Marines.

‘How rude,’ said Malinko, firing up his flamer. A small gout of fire came out of the nozzle, but was extinguished by the lack of oxygen. ‘Also rude,’ he added, switching to his bolter.

‘Cease your chatter,’ shouted Hulpin over the vox, as he opened fire on the humans, ‘and kill something.’

‘I second that order,’ said Rotaka, raising his bolter and firing at one of the mortals emerging from the bunker before they could take cover behind one of the many boulders on the rock-strewn plain. Another mortar shell flew into the air, then dropped close to the empty pod, missing the Red Corsairs.

Rotaka mentally tracked the flight of the mortar shell to a ridge of rock near the bunker entrance.

‘Kill anything that comes out of that bunker,’ he ordered. ‘I’ll deal with this.’

Ducking low, Rotaka ran towards the ridge, weaving around large rocks in his way, until there was only a lumpy boulder half his height between him and the ridge. He ran straight at it, jumped right foot first, caught the top of the boulder with his boot and propelled himself over the ridge. As he fell towards the atmosphere-suited mortals manning the mortar, it fired; a shell powerful enough to crack open power armour sailed narrowly past his shoulder.

Rotaka opened fire with his bolter, killing two of the mortals manning the weapon. There was a third attempting to raise a lasrifle, and as Rotaka landed he kicked the mortar out of its base, the barrel of the weapon smashing into the chest of the third mortal and knocking him off his feet.

Knowing that no ordinary human would come back from a blow like that, Rotaka ignored the mortal and instead aimed his bolter at the ones advancing on his squad, running between cover. Now Rotaka had broken their line he was behind them, and shot three mortals in the back in quick succession. A little further away he could see Malinko and Verbin starting to fire on enemies they hadn’t realised were now dead.

‘All down,’ voxed Rotaka. ‘You’ll need to be quicker than that.’

As his squad emerged from cover and advanced on the bunker, Rotaka ignored Verbin’s colourful suggestions regarding his leadership.

Raising the blast shutters to look out upon the barren surface of Laghast, Kardon had seen the drop pods falling to the west of her control centre.

Her view in the other direction was obscured by the curve of the central dome. Communications were still down. For all Kardon knew, there could be more pods landing to the east as well, but she could see pods landing to the west, so that was where her Jandarme would make their stand.

The weapons batteries were ablaze, enemy ships filled the sky, and they had no way to call for help. Lieutenant Kardon was determined to meet their enemies, face to face, regardless of how briefly, and meet them with force.

‘They’re coming from the west,’ Kardon ordered, looking at the atmosphere-suited men and women gathered in the control centre. As all communications beyond the most local helmet-to-helmet vox had been consumed by eerie, nightmarish white noise, all nearby Jandarme had reported to the control centre. There were three dozen or so of them now, armed and waiting for orders. ‘They’ll have to get through Docking Bay Theta. We’re no use here, so we move out and meet them there.’

There was a chorus of ‘ayes’ and nodding visored heads, a defiant raising of weapons, and they moved out. Although none of them had faced anything like this before they were a disciplined force, spreading out to cover the corridors leading towards Docking Bay Theta.

They entered the docking bay to find it still secure, an open area with many layers of gantries around the edge of the central space. Kardon ordered the men and women under her command to take positions in cover. She herself took a position at the rear of the bay, away from the towering doors that opened out onto the surface. From there, she had a view of the entire bay. It was a dimly lit space, loading equipment and crates scattered around from work disrupted by the attack, eerily quiet. She could see Jandarme positioned behind loaders and other equipment, lasrifles held tightly, while up on the gantries sharp-shooting positions were taken.

While atmosphere held within the bay, the Jandarme were all fully suited, rebreathers pumping air into their helmets. The bay was designed to open out onto the airless outer surface of Laghast, and Kardon was certain the invaders would not take safety precautions when they breached the bay.

Behind her, she knew preparations were being made to further secure the corridor into Laghast’s interior. A squad had been dispatched to make the descent and alert the interior. Kardon and her troops were just the first of many lines of defence that would stand between the attackers and the rest of the Hollow Worlds. Kardon knew there was a good chance they would all die here, but she was damned if she wouldn’t make the enemy fight for every step. For an enemy to actually make planetfall on Laghast’s surface was an unprecedented affront, and it was happening on her command. The least she could do was stand with the men and women of the Jandarme who she had ordered to face this threat.

Corporal Tusc was nearby, sheltering behind the same loading vehicle as her. Kardon knew that he would fight to the last, though with his history, probably die first. Kardon was struck by the pathos of that, but any further ruminations on the nature of life and death were interrupted by the far wall of the bay being blown to pieces.

Rotaka’s intention to get ahead of Becaro and his squad had not gone to plan. The two squads had converged, along with others, as they fought against waves of atmosphere-suited mortals through the outskirts of the Hellward Gate.

Ahead, they could see a lander hovering over the central dome of the gate. The Tyrant’s personal shuttle, taking him straight to the heart of the action. That was where Rotaka needed to be – he just had to clear the way through the throng of human scum first.

They entered the Hellward Gate complex via a loading bay to the west of the main dome, one of Becaro’s squad firing a krak missile right into the great shutters that sealed the bay from the airless world outside. The explosion was followed by an outrush of air and debris as the atmosphere seal broke.

‘Charge!’ shouted Becaro. Rather than dispute the chain of command, Rotaka set an example by breaking from cover and running directly at the breach in the doors. Becaro, crackles of energy running from his gauntlets and over the bolter he was wielding, kept pace and they leapt through the breach together, their squads on their heels.

Rotaka landed within the bay to find himself in a drab industrial space with scattered loading equipment. He also found himself under fire, las-beams cutting through the air at all angles. Rotaka and Becaro instinctively separated, heading in different directions. Rotaka fired in the general direction of the bay’s defenders, to provide covering fire as the rest of his squad entered the bay. The first couple of bolts he fired were shots in the dark, but that was all it took for him to identify that the enemy were gathered at the other end of the bay. Mentally tracing the las-fire back to its source, Rotaka fired tightly directed shots in that direction. Even as he did so, his focus was beyond his current targets, past this docking bay and towards the Pit, and glory.

‘Push ahead,’ Rotaka ordered, restricting the vox-channel to his squad only. ‘Let Becaro deal with this scum – we’ll take the Pit for Lord Huron.’

Malinko didn’t need to be told twice. He ran into the centre of the docking bay, racing ahead of the other Corsairs, making himself a target.

A volley of las-fire came from a group of mortals concealed behind a row of barrels – Malinko turned and released a single, long gout of fire from his flamer, enough to ignite whatever volatile substance was in the containers. The humans ran screaming, spatters of burning, toxic slime eating through their atmosphere suits into the skin beneath.

Before he could pick another target, Malinko was nearly blown to pieces by a rocket, exploding against the rockcrete floor near enough to reverberate through his power armour, blurring his vision and disrupting his hearing.

Half-blind and deaf, Malinko could not have been happier. This was battle, raw in its madness and fury!

Letting his flamer hang at his side, useless now the last of the oxygen had drained from the docking bay, Malinko drew his bolter to take out the two men reloading the rocket launcher on a high gantry. Even with his senses befuddled it was a simple, instinctive task to track the rocket back to its point of launch and eliminate the problem at its source. His aim was true and the two men collapsed, one clutching a gaping wound in his chest and the other losing his head from the chin up. Malinko appreciated the effort they had put into trying to kill him. The distortion of his senses was the most interesting thing to happen to him in years.

Hopefully the next explosion would be even closer.

Advancing rapidly across the docking bay, Rotaka saw his squad tearing through the enemy from different approaches. While Malinko was recklessly barging around the bay at ground level, Verbin had taken a run straight for the lowest level gantries, and was fighting his way hand-to-hand up the levels. Where he went, bodies fell, and the floor beneath was reddened where corpses had fallen.

Wuhrsk was taking out targets steadily, while Hulpin had let his chainfists lie idle for once, joining Rotaka in a steady advance across the floor of the bay, gradually forcing the mortals further back towards the rear of the bay, whittling down their numbers as they went. As they pushed forwards, Rotaka and Hulpin had to step over or kick aside more and more corpses brought down by the Corsairs’ bolter fire.

Over the command vox-channel Rotaka heard Becaro order his squad to secure the area and eliminate any resistance. This first strike would be over soon – the Lastrati fought well enough, for spineless humans in thrall to a hollow corpse-god, but they were grossly outgunned.

However brave they might be, they were mortals and the Red Corsairs were gods.

Rotaka eyed the other end of the bay.

‘This is our chance to leave Becaro behind,’ he told his squad. ‘Get ready – charge on my word.’

Although the series of explosions that hit the Hellward Gate had seemed like a worst-case scenario, Tusc’s nightmare had truly begun in Docking Bay Theta.

The bay had been overrun with monsters, ferocious giants whose armour was scarred with hideous symbols and festooned with grotesque trophies. They moved faster than anything he had ever seen, and their weapons spewed death across the loading bay, tearing through the flimsy crates and barriers that the Jandarme were using as cover, exploding in the bodies of their enemies.

By this time the air had fully drained from the bay. They were fighting in a vacuum, and though Tusc could see the carnage, he could not hear a thing. He mutely fired his lasrifle at targets who either shrugged off the shots or were somewhere else altogether by the time the shot cut through empty space. Huge though these creatures were, they were quick, rolling across the floor and onto their feet in seconds, leaping a distance three times taller than Tusc to land on a gantry above.

Nearby, he saw Lieutenant Kardon dodging between cover, slapping Jandarme on the shoulder and giving pointed orders. With verbal communications badly compromised, they were left with gestures to provide commands. As Kardon sprinted back towards his position, running in front of an airlock door leading to the Pit, Tusc provided defensive cover, raising his lasrifle to fire on the approaching giants.

As he shot at the enemy moving towards him, Tusc didn’t even notice the one coming from above, jumping off a gantry to land on him with both boots, crushing his spine and killing him instantly.

Rotaka barely noticed the two Jandarme ahead of him as he made for the airlock. He was vaguely aware of two atmosphere-suited figures, but Verbin landed on one as he jumped off the gantry, and cut the other in half with a swipe of a chainfist.

Running to the airlock, Rotaka jumped over the corpses without a thought. Pausing only to unleash some suppressing bolter rounds at a group of humans who foolishly considered that, away from the main body of Corsairs, they had him and his squad trapped, Rotaka slapped a magnetic charge onto the locking mechanism of the airlock’s door, and stepped back.

The charge blew that part of the door to pieces, chunks of smouldering metal scattering across the floor, and left a hole that didn’t quite reach the sealed interior of the airlock. It did, however, give Rotaka a handhold, allowing him to manually pull the door aside, albeit with a grunt of effort.

The interior door of the airlock snapped shut as Rotaka ripped the exterior door away. He punched the button to open the inner door, knowing already that safety mechanisms were clicking into place to secure it. Doors like this were the same across the Imperium, and Rotaka simply punched through a plasteel panel above the door, seized the override lever, and pulled it hard.

The door opened with a hiss of escaping atmosphere. Rotaka stepped through, let the rest of the squad in, and manually forced the door shut – any atmosphere difference would cause every bulkhead in this section to drop down, delaying progress.

A crude barricade had been erected across the corridor, and whoever was behind it opened fire as Rotaka and his squad ran towards it. The las-fire shots were poorly aimed, and Rotaka drove at the barrier with his shoulders down, crashing through in one movement and crushing the mortals under their own defences.

‘You’re turning into me,’ said Verbin over the vox, coming up behind Rotaka and kicking a mortal to death with one blow as he tried to get up.

Rotaka didn’t answer, but kept moving. The corridor was built for mortals and the Red Corsairs could only run two abreast. Verbin ploughed ahead, smashing another barricade and the men behind it as if they were mere tinder. Rotaka ran through after him, followed by Malinko, Wuhrsk and Hulpin.

Then they burst through into the central dome of the Hellward Gate, and found the battle for the Pit was fully under way.

The Pit was the doorway to a whole world, a shaft through the very crust of Laghast that led from the exterior surface to the habitable inside. Capped by the huge dome, the Pit was circled with machinery, great rigs and elevators that carried troops and cargo up and down the shaft, strong enough to negotiate the change in gravitational forces. The Pit itself was huge, large enough for the Corsairs to manoeuvre their tanks and galleons down, though not large enough for flyers.

As Rotaka and his squad entered the huge chamber, the last dozen or so mortals surrounding the Pit were on the verge of defeat. Red Corsairs were approaching from all sides, having landed around the complex and pushed their way in as Rotaka had done, firing on the atmosphere-suited mortals. The defenders were stubbornly entrenched behind a barrier of heavy loading equipment.

The airlocks had closed behind the Corsairs, and so when Huron Blackheart entered the dome everyone present, Corsairs and mortals alike, heard it.

It was no word that Lord Huron shouted, but a feral bellow of rage. He entered the dome via a high gantry, running off the edge and leaping towards the cover where the remaining mortals were firing from. As he dropped to the ground he let out his war-cry, and Rotaka could only imagine the effect it had on the mortals.

Huron landed next to the huge loading vehicle that made up the main part of the mortals’ cover. He swung around the Tyrant’s Claw and dug into the metallic side of the loader with the blades, a high screech echoing around the dome as metal tore into metal. Then he pulled the loader aside and tossed it away, throwing it like a toy. The Red Corsairs dodged as the loader tumbled towards them, cast aside by their lord with no thought for his followers.

Cover removed, Huron tore the last human defenders to pieces, shrugging off las-fire and tossing mortals aside with his claw. As the last mortal made a futile run at Huron Blackheart, lasgun raised, the Tyrant kicked the weapon out of his hands, reached forwards and broke his neck with a single twist of his hand.

Towering over the crumpled bodies, Huron Blackheart turned to his men. The scarred red of his armour was splashed with blood, and his artificial eye glowed from his ruined face.

‘Into the Pit!’ he bellowed, immediately turning back and leaping over the edge.

None of them hesitated, jumping into the Pit, falling down a shaft so deep that even a Space Marine might die when he hit the bottom – not that there was any bottom to this pit, as halfway down they would hit the gravitational anomaly that marked the transition to Laghast’s interior.

Rotaka was amongst them, falling. He dived as gracefully as he could in power armour, keeping his arms by his side so he cut through the air.

The metallic sides of the Pit shot past, the ridges and gantries clinging to the wall blurred into thin streaks. As his speed increased, even with the enhanced senses of a Space Marine, Rotaka couldn’t make out his surroundings. His fellow Red Corsairs were the only things in his line of sight moving at the same speed. Ahead of him flew Blackheart himself, moving his entire body subtly to redirect his fall.

As they fell, the air streaked with light and fire – mortals on gantries presumably firing blindly as the Red Corsairs streaked past in their descent. These efforts were not entirely futile – one of Rotaka’s fellow Corsairs jerked backwards in an explosive burst, a lucky shot hitting him and halting his momentum.

The unfortunate Corsair was out of Rotaka’s line of sight within less than a second, left far behind. He had no way of knowing if his descent was still true, or whether a glancing shot was enough to throw one of the falling Space Marines off course. At their speed an impact with a wall or gantry would be enough to dash the power armour right off them, the friction alone setting their bodies ablaze.

Ahead of Rotaka, Huron curved his body around, as if bracing himself for impact. Rotaka could not see whatever Huron perceived ahead – and he knew that his master perceived things that Rotaka would never, could never, see – but tried to do the same nonetheless, bending his armoured body so that he was falling feet first.

Rotaka hadn’t quite managed to achieve this when he found himself slowing. There was no impact or friction, just a sudden draining of momentum. There was a feeling of sinking, of being dragged down rather than falling, and then a very familiar sensation.

Weightlessness, the absence of gravity. Rotaka was no longer falling; he was floating.

‘Attack,’ shouted Huron Blackheart, and Rotaka saw that the Corsairs were not alone. The Lastrati had prepared for them, banks of weaponry mounted on gantries around the circular wall of the shaft.

This pocket of zero gravity in the central stretch of the Pit, the transition point between one gravitational field and another, had been made into a kill zone that the Corsairs had fallen straight into.

A mortar narrowly missed Rotaka, exploding as it hit the gravity barrier behind him. The pressure from the explosion threw him forwards, towards the ledge where the Lastrati manning the mortar were sheltered behind a plasteel barrier. Rotaka opened fire with his bolter, but failed to breach their shield.

He activated his jump pack, boosting him across the space between him and the heavy weapon. The mortar fired another shot, but it sailed over Rotaka’s head.

He hit the wall a slight distance away from the shield, his boots locking to the surface of the wall. Not bothering to draw his bolter, Rotaka ran across the wall, jumped over the barrier and kicked the man behind it in the face. The man was anchored in zero G by a flexible cable attached to a rail running up the wall, so as he flew backwards he rebounded, bouncing back towards Rotaka, bloodied and bruised. Rotaka, now firmly standing on the wall, slammed his palm beneath the man’s chin, snapping his neck. He drew his knife and cut through the safety cable with a single slash, allowing the corpse to drift off.

The mortar was locked to the wall, but it was little effort for him to rip out the fittings and lift the weapon. He looked up, to see a similar mortar placement on the opposite side of the pit firing upon Malinko and Wuhrsk, who looked to be drifting aimlessly.

Rotaka aimed the mortar across the vastness of the Pit. The mortar shell spiralled across the shaft, blowing the mortar crew opposite to pieces.

‘Get on the wall,’ Rotaka snapped into the vox, abandoning the mortar and running up the wall. ‘Target the heavy weapons. Keep them too busy to fire on anyone else.’

‘Insanity!’ cheered Malinko. ‘I like it.’

Ahead, a heavy lascannon was firing on the Red Corsairs floating through the Pit. Rotaka raised his bolter and fired at it, killing the Lastrati controlling its operators.

All around he could see mortal weapons being hijacked or destroyed by the Red Corsairs, who were mostly now running up the wall of the Pit. A few had been killed by the Lastrati weapons, but most of Huron’s force were alive. The Tyrant himself was floating through the centre of the Pit, propelled by some unseen force, keeping ahead of the rest of the Corsairs.

Rotaka wasn’t sure whether Huron had seen the mines, or whether the Tyrant’s mystical gift for circumventing physics would allow him to dodge them without any aid. All he saw was the release of large, spiny metallic spheres from launchers in the walls of the Pit, the mines spreading across the space in the centre, and Huron drifting towards them. Rotaka didn’t think but acted, jumping off the wall, using his jump pack to boost himself towards his lord.

Huron looked around, enraged to see Rotaka hurtling towards him, that rage not subsiding as the captain slammed into his master, knocking him out of the way of a mine. Rotaka ricocheted out in a different direction, but clipped the mine as he did so, spiralling away from it and only escaping a short distance before catching the blast.

He spun head over heels, warning runes flashing in his helmet display, his jump pack not responding, unsure whether he was about to crash into the wall or be shot out of the air by a Lastrati weapon.

Just as the runes on his display settled down, indicating no permanent damage to his power armour from the blast, Rotaka felt a tug as some form of gravity began to reassert itself. They had reached the second transition point, where the gravitational field of Laghast’s interior took hold. Rotaka had only seconds in the nebulous swirl of gravitational forces between the zero gravity section of the shaft and the next to act: if he drifted too far forwards the gravity would force him backwards into zero G; he would be trapped until he found sufficient momentum to break out again.

Rotaka used his jump pack and the unstable gravitational currents swirling around him to launch himself towards the wall of the shaft. As he drifted he felt competing forces pulling at him, but reach the wall he did. He took a handhold and began to climb up – for the shaft ahead was now definitely ‘up’, rising away from the exterior of the planet – his fingers finding grooves, pipes and ridges to grasp on to, his boots magnetically locking to the wall.

Around Rotaka, other Red Corsairs were doing the same. While nothing could have prepared them for the gravitational anomalies of the shaft, they adapted quickly.

‘The gods are with you today, Rotaka,’ said Hulpin, climbing up beside him, his chainfists digging into the wall of the shaft like picks. ‘They guided you to safety.’

‘I’m glad they have my back better than my squad do,’ said Rotaka, biting back the desire to tell Hulpin that he saved himself, no gods required.

‘I didn’t want to interrupt,’ interjected Malinko over the vox. Rotaka couldn’t see him nearby – presumably he was on the other side of the Pit. ‘You seemed to be enjoying yourself.’

‘Targets ahead,’ said Wuhrsk, also out of sight. ‘If any of you are still interested.’

The Lastrati were now at a brief disadvantage, having to fire over the lip of the platforms and elevators they were standing on to target the climbing Red Corsairs, who were nestled tightly against the wall, often in the protective shadow of the platforms. Rotaka looked up to see the smoking bodies of two mortals falling off a platform directly above his and Hulpin’s position.

‘Got them,’ voxed Wuhrsk.

Rotaka glanced across the Pit to see Wuhrsk holding on to the wall one handed, bolter raised.

Above Wuhrsk’s position, Rotaka saw Huron, using the Tyrant’s Claw to grasp a section of wall, throw himself upwards and then grab the wall again before gravity pulled him back down. It was an extraordinary display of agility and raw power, and Huron left a shower of metal scrap and shattered rock tumbling behind him with every leap.

His lord was climbing in the space between two tracks that ran the length of the shaft allowing elevators to carry cargo and passengers back and forth, the platform rotating as required to match the gravitational alignment. Someone above Huron had clearly noted his presence, as an elevator platform began to drop towards him, a wide metal platform heavy enough to crush even the leader of the Red Corsairs.

‘Lord Huron, above you,’ Rotaka shouted over the open vox-channel.

Huron looked up, and Rotaka heard him laugh over the vox as the elevator dropped towards him.

Just as the elevator was about to hit him the Tyrant sprang away from the wall, arcing out of its way. The elevator cut through the air where, half a second before, Huron had been, and as it passed him, he reached out and grabbed the lip of the platform with his claw. He swung up onto the elevator to face a dozen armed Lastrati. The elevator stopped automatically before it could reach the transition to zero G, and the climbing Corsairs looked down as their master faced the defenders.

They were nothing to the Tyrant, whose claw slashed through the nearest four in one smooth motion. The two hit by the claw first were slashed into pieces, bodies falling to the platform in bloody chunks, while the other two were scooped up and batted off the edge of the elevator. Their screams echoed up as they fell.

The other Lastrati had barely raised their weapons when Huron lifted the Tyrant’s Claw once more and spat fire from its palm, setting half a dozen of them ablaze. More Lastrati went over the edge, thrown or forced over by Huron’s blows, some already dead and others still dying, and the jeers of the Corsairs rang out as they fell in a trail of smoke.

The last two Lastrati standing both fired at Huron, but couldn’t stop him. He backhanded one, smashing her into the wall so hard she slid down, a shattered mess, then impaled the other on a single blade of the claw, raising his corpse up so that the Corsairs could see.

The Tyrant of Badab had destroyed a dozen fighting men and women within a minute, and bellowed his bloodlust to his Corsairs, who roared their approval.

Rotaka, precariously hanging from the wall, cheered as loudly as any of them.

‘My Corsairs,’ bellowed Huron, his voice amplified into every ear by the vox-network. ‘Take the elevators, and then we’ll take this world.’

Then, looking straight across the Pit, Huron spoke to Rotaka on a private vox-channel.

‘You have done well, Rotaka,’ said Huron, nodding towards his subordinate.

‘My lord,’ said Rotaka, and then Huron’s attention was back on the battle, and the vox-channel closed.

Although the compliment filled him with pride, Rotaka also felt a chill of trepidation – to be singled out by the Tyrant was not always an honour.

Some of the Corsairs closest to Huron’s elevator threw grapples, pulling themselves up to join him. Rotaka was too far away to be one of them, and instead he kept climbing towards the platform immediately above him.

When Rotaka reached the elevator platform, he found nothing but the bodies of Lastrati shot by Wuhrsk. He voxed the rest of his squad to demand to know what was keeping them.

‘Nothing,’ said Wuhrsk, climbing alongside the elevator and dropping onto the platform. ‘If you had eyes for anyone other than Lord Huron, you would have noticed.’

Rotaka didn’t respond to that as Hulpin swung across from a maintenance platform, rolling to a halt nearby.

‘The gods are with us in this battle,’ said Hulpin enthusiastically. Lastrati corpses were raining down the centre of the shaft, evidence of Huron’s progress above.

‘Gods,’ said Wuhrsk, shaking his head. ‘Can’t we take a little credit for ourselves? We abandoned one oppressive deity, why so quick to adopt another?’

‘Blasphemer!’ barked Hulpin, marching towards Wuhrsk.

It was a familiar conflict between the believer and the cynic. Rotaka stepped between them, lashing out with his gauntleted fists to smack both of them in the chestplate. Wuhrsk backed off with a low chuckle while Hulpin stood and seethed.

‘The gods guide Huron,’ snapped Rotaka. ‘And we follow him. That’s all that matters.’

‘Of course,’ said Wuhrsk. ‘Of course.’

Hulpin said nothing, but nodded.

Malinko and Verbin had joined them during the conflict, as had another squad of Corsairs and a couple of strays separated from their comrades in the battle.

‘Where do we go from here?’ said the other captain. Red Corsairs deferred to each other rarely, but being first to capture a ship or area gave precedence.

A chunk of flaming metalwork fell past them, a screaming mortal dragged behind it by burning cables. Rotaka looked past it to see a deserted maintenance elevator within climbing distance. He pointed at it.

‘We do as our lord commands,’ he said. ‘Let’s take the elevator. We go up.’

Six

Commissioner Krayk had risen within the ranks of the Jandarme to take charge of the whole operation of the Hellward Gate, both on the outer surface of Laghast and within the interior. The Inner Dock, the part of the Hellward Gate that emerged within Laghast’s inner, inhabitable surface, was based on an island in the centre of an ocean. It was in many ways a more hospitable mirror of the Hellward Gate on the outside of the planet, a complex of port facilities based around a central dome, underneath which lay the Pit.

Krayk knew every part of the operation under his command, both on the outer surface and on the island, and appreciated more than anyone else the extent to which the Lastrati’s use of the gate was crudely overlaid on ancient systems none of them understood. Whatever purpose the architects of the Hollow Worlds had for having the Pit open on a small island, it wasn’t the same as humanity’s. The island was far too small for a complex operation like the Inner Dock, and loading spaces were clustered upon generators and other industrial equipment. Only through strict discipline could everyone work together in such a crowded space, and one random element could grind everything to a halt.

The disruption that was spreading through all internal communications was already fully occupying Krayk’s attention, but such problems were not unexpected.

The first evacuees to emerge from the Pit, carrying a message from Lieutenant Kardon in person, were another matter. They were civilians, with one message on their lips, spoken to anyone they encountered: We are under attack, enemies unknown but powerful.

Krayk was near the Pit when the evacuees came through. He had served in the Jandarme all his adult life; he knew as much of the Hellward Gate’s operation as anyone, but this situation was unprecedented.

‘Lieutenant Roote, form a defensive line around the Pit,’ Krayk barked. ‘Adept Skrif, close the Iris. Beil, raise the alarm and spread the word – I don’t want a single Jandarme thinking this is a drill. I want them armed and ready. Dunt, begin evacuating civilians – they’ll just get in the way.’

Krayk was already at the door when he turned to Mikal. If all else failed, there was one last option open to him, one that could only be activated from his command centre, and for that he needed hard intelligence, an accurate report of what exactly they were up against. Without comms, with every standard monitoring system and visual feed corrupted, he needed an eyewitness.

Mikal was young, with barely six months on the job, but he had two vital skills: keen eyesight, and the ability to run like a maniac.

‘Mikal,’ Krayk ordered. ‘If these attackers breach the Iris, I want to know who they are. As soon as you see them, run to the control centre to tell me. Do not stop to fight or help – come straight to me even if it means leaving everyone else to die, understand?’

‘Yes, sir,’ snapped Mikal with a hasty salute, but the commissioner was already gone.

It was called the Iris because that was what it looked like, if you were in the Pit when it closed. More prosaically it could be described as a cap or a lid, a retracting barrier made of many curved, overlapping sections that emerged from the rim of the Pit to seal it, reducing the opening to a pinprick before locking altogether, forming a barrier metres thick. It was an ancient mechanism, part of the Pit’s original construction, the power source that sealed it and any control systems long lost to time. When the Iris was closed, as it was in drills twice a year, it had to be done manually, with brute force.

As the Jandarme under Roote’s command erected makeshift fortifications around the Pit, the air was filled with the screaming of ancient, rusty chains and the gears of the closing Iris. Over a dozen adepts and servitors, supervised by Adept Skrif, operated the roaring generators and oily control panels that fed chains and pulleys into a deep trench by the side of the Pit, manipulating great gears beneath the ground. The adepts chanted as they worked, incense rising from burners and thickening the air, smoke gathering in the centre of the dome over their heads.

Slowly, steadily, the Iris began to close. Roote let himself feel some small relief, but as solid a barrier as the Iris was, Roote was achingly aware that the threat they faced had unknown firepower. Kardon’s warning had been maddeningly non-specific, but she was not one to exaggerate.

Whatever the threat, the Jandarme had trained their entire lives to combat it, and Roote felt a swell of pride as he watched the men and women under his command taking defensive positions around the chamber that surrounded the Pit. They were ready.

Then he heard the gunfire, from the depths of the Pit, and Roote felt a lurch of uncertainty in his stomach. Was that the sound of defensive or offensive fire? Friend or enemy?

The Iris was only half closed. The Pit was still open.

‘Skrif,’ Roote shouted, his grip tightening on his lasrifle. ‘We need the Iris closed now.’

Rotaka had started to see a circle of light above some time ago, getting larger and larger as the Red Corsairs fought their way up the Pit, towards the interior of Laghast.

Then, as the Lastrati defences within the Pit seemed to be petering out, Rotaka realised the circle of light was now getting smaller. Some form of shield or door was closing over the top of the shaft.

Rotaka quickly assessed the situation in the Pit itself: of the Corsairs climbing the walls of the shaft, he was closest to the top, having abandoned the elevator when it reached its limit. It would be wise to storm the rim of the Pit in great numbers, as the Corsairs would be most vulnerable to an attack at that point. To leap into that killzone alone was near suicide. Even worse, it would require him to use a jump pack that was perilously low on fuel.

That circle of light was getting narrower, though, and Rotaka’s jump pack could have enough juice in it to–

Rotaka swore and fired the jump pack, speeding towards the light. As he roared upwards he heard Lord Huron screaming over the vox for the Corsairs to get out of the Pit and stop the mouth closing. Rotaka’s entire body shook as he pushed the jump pack to its limits, a barely controlled ascent that sent him hurtling towards a disc of light that seemed perilously small. At the speed he was going, Rotaka would smash into a solid surface hard enough to crush even power armour, then ricochet back down into the Pit.

The pauldrons of Rotaka’s armour screeched as they scraped through the closing circle, and he shot out into a domed chamber similar to the one at the other end of the Pit. He killed the thrust of his jump pack, his momentum carrying him close to the curved rockcrete before he plummeted downwards, gravity reasserting itself over his immensely heavy, power-armoured form.

Mortals started shooting at Rotaka before he had even hit the ground, las-fire coming from all directions. He landed clumsily on all fours, the dead weight of the cooling, inactive jump pack pulling him over, disturbing his balance.

A bolt shell exploded against the rockcrete floor near his right foot before he could stand, throwing him into a sideways roll. As he tumbled away from the blast, las-fire scorched his armour in multiple places.

As he rolled, Rotaka took a breath, and assessed the situation. The chamber was wide, circular to match the vast Pit at its centre. Loading equipment and crates had been overturned and piled up to create cover for countless mortals, all of whom were presumably targeting Rotaka. He counted a dozen, two dozen muzzle flashes in his line of sight in a single second, glimpses of uniformed mortals smoothly exiting cover to fire, then disappearing again. Those were just the ones in his field of vision.

Even power armour could not hold out against such a sustained attack for long.

Rotaka looked harder, past the blur of las-fire, the smoke and shrapnel. Then he saw it, beyond a couple of adepts of the Adeptus Mechanicus, who were advancing towards Rotaka, guns raised and firing. Over their shoulders, a cluster of figures surrounding decrepit-looking mechanisms, huge chains disappearing into the floor.

That had to be it. Rotaka slammed his left fist into the jump pack release on his chest, letting it fall away. He scooped up the bulky jump pack and disabled the failsafes. Pointing it towards the advancing adepts he punched the thrust sigil on the pack so hard the control was completely crushed. Set to permanent thrust, the jump pack shot out of Rotaka’s grip, knocking him backwards and scorching the chestplate of his power armour, flames licking at the muzzle of his helmet.

The jump pack, designed to lift a fully armoured Space Marine, barely slowed as it crashed into one of the adepts, embedding itself in his chest and lifting him, limbs flailing, off the ground.

As Rotaka fell back he took hold of the bolter magnetically locked to his thigh and raised it, targeting the jump pack as it, and the adept it had slammed into, flew towards those heavy, ancient chains.

The air between Rotaka and the jump pack was criss-crossed with las-fire, blurred by smoke and activity.

Rotaka squeezed the trigger.

The bolt shell hit the jump pack and the fuel within – whatever precious traces were left – exploded with tremendous force. The adept was shredded, exploding into fragments of flesh and augmetics, and there was a huge crack that echoed around the entire chamber.

As Rotaka skidded to a halt on his back, he could see that one of the great chains was broken, a link shattered by the explosion. The two parts of it disappeared in opposite directions, the tension broken. There was a fierce rattling, and further snaps and cracks as other parts of the mechanism broke under the increased pressure.

Rotaka was on his feet, the gunfire in his direction slightly abated for a second due to the carnage he had caused distracting his attackers, and he looked across at the mouth of the Pit.

Soundlessly, the layered pieces that had slid together to close the mouth of the Pit disappeared back into the rim, the machinery that had crudely caused them to close now destroyed.

‘The Iris is open!’ a human shouted, and Rotaka allowed himself a twitch of a smile as, even under heavy fire, he knew these mortals were doomed.

Roote barely managed to catch a glimpse of the creature that had emerged from the Pit as the Iris closed, just a brief impression of dark-red armour as a huge figure landed in the chamber. Then everyone within range, himself included, opened fire on the armoured giant. The air had filled with gunfire, and the creature seemed to dodge and weave, then throw something at the mechanism that closed the Iris, and then there was a roar of dying machinery and the Iris was open again.

Roote was about to order his men to redirect some of their fire to the Pit when he emerged and Roote lost all ability to speak.

The figure that leapt out of the Pit was even taller than the first armoured giant, his armour blood red and one of his hands a gigantic armoured claw, each finger tapering to a wickedly sharp blade. In the other hand the creature swung an enormous axe. As the towering figure landed on the ground the axe lashed out, cutting through three of the Jandarme as if they were paper. Rather than slashing with its clawed hand, it opened the claw to reveal a palm that belched out fire, consuming two more of Roote’s men in flame. As it did so, the figure raised its head, a head haloed by a golden arch covered in gold spikes, and looked Roote straight in the eye.

While Roote was at the far side of the chamber from where the creature landed, three dozen paces and two defensive lines of Jandarme between them, he still flinched. It was a face of inhuman cruelty, scarred and lifeless flesh stretched over the bone and peppered with wounds showing the skull beneath. A metal plate was drilled into the scalp, and one eye was a glowing red augmetic sphere connected to some unseen power source by a cable that trailed down into the thing’s armour from where its ear should have been. While the artificial eye glowed fiercely, the organic eye was more terrifying still, cataract-white but somehow intently staring at Roote as the creature’s ragged mouth opened into a cruel grin.

While it had the shape of a human, this thing was too enormous, too grotesque to think of as a person.

It was a monster, an atrocity on two legs. It had to be destroyed, however many lives it took.

It took only a handful of horrified seconds for Roote to come to this conclusion, but in that time half a dozen of the Jandarme had already been killed.

‘Concentrate your fire!’ Roote shouted, raising his own lasrifle and aiming at the thing’s unarmoured head. ‘Bring their leader down.’

Jandarme emerged from cover across the room, energised by Roote’s defiance and opening fire. Las-fire criss-crossed the chamber, focusing on the monstrous giant. Roote advanced on it, rapid firing his lasrifle in controlled bursts.

Then his target was gone, leaping away from the crossfire with incredible speed, barrelling into a group of Jandarme and batting two aside with its gigantic claw, cleaving another in two with its axe, spinning between enemies too fast for Roote to aim at. There was an explosion near Roote, a young Jandarme falling back with a gaping wound in her chest, and Roote looked across to see that the first giant to emerge from the Pit was up on its feet, firing on every Jandarme in sight. Roote could see it better now, the curve of its reddened armour, the shape of its helmet, and even in the heat of battle Roote knew there was something familiar about it.

‘What are they?’ shouted Mikal nearby, sheltered behind a crate, and Roote remembered the commissioner’s orders, for Mikal to identify the enemy and report back.

‘I don’t know, damn you,’ snapped Roote, but he still had the feeling that he did know somehow, that he had seen that armour before.

Then the rest of them came, not pulling themselves over the lip of the Pit, or rising gently on the elevators, but leaping over the edge en masse, firing before they even hit the ground, huge figures in tarnished, bloody armour decorated with skulls and other trophies, some horned, some fanged. A flood of armoured horror unleashing a torrent of bolter fire on the Jandarme. Roote nearly lost his senses in that moment, but his sense of duty overcame the wave of terror and despair he felt at these abominations, these grotesque distortions of…

Roote remembered then. The crude representations of the Adeptus Astartes on friezes and tapestries, the heroes of the Imperium. But these were not heroes, not true creations of the Emperor, and Roote recalled whispered rumours of the most terrible treachery and–

‘Fight to the last man,’ he shouted, knowing that they were all doomed, that there was no hope in the face of enemies like this, but that the Jandarme would make them struggle for every step they took on Lastrati soil. And Mikal could still get to the commissioner, with news of what they faced.

‘Run,’ Roote bellowed at Mikal. ‘Tell the commissioner: Traitor Marines. These are Traitor Mari–’

Lieutenant Roote died mid-sentence, a bolt shell hitting him in the shoulder and exploding, tearing through flesh and bone. The lieutenant was flung sideways by the impact. Mikal saw blood spill from his lips and his pupils widen glassily. He had never seen a man die like that, and felt a wave of nausea come over him as the body hit the floor.

Mikal couldn’t comprehend what the two words Roote had told him meant: Traitor Marines. His mind had ceased to fully understand what was happening since armoured giants had emerged from the Pit and started slaughtering his fellow Jandarme in a fury of blows and gunfire.

But Mikal knew his orders. He scrambled to his feet, and ran for the door that led up and across the Inner Dock to the control centre.

Traitor Marines. The words repeated in his mind – he had never heard them before, had never even been aware that such a thing could exist, but now those two words were all he could think as he ran.

Traitor Marines.

As reinforcements poured into the domed chamber, Red Corsairs flooding over the rim, their mortal opponents stood no chance. They fought well and held their ground, and they had been well prepared with cover and sound firing positions, but they were no match for the Corsairs and could do little but die. Having been attacked from all sides when he first entered the chamber, as the tide turned it was Rotaka who was on the attack. He leapt on a mortal who was targeting Huron Blackheart, crushing his enemy’s spine as he landed on him. Rotaka searched the chamber for a mortal target who was not already about to die at the hands of a Red Corsair.

Looking to the far end of the domed chamber, something caught Rotaka’s eye, a slim figure running for the door. As he ran, none of the other mortals attempted to stop him or cut him down, so he wasn’t deserting. He was on a mission.

Rotaka decided that whatever mission this enemy was on, whatever message he had been sent to deliver, he would not fulfil it.

Mikal ran towards the exit that led to the Inner Dock’s control centre. While the large loading bay doors that allowed cargo and vehicles to be moved out of the dome had been locked down to slow the attackers’ advance, this smaller exit had not. He paused to press a sigil that opened the door, then ran through it into the simple, dark corridor that led to the Inner Dock control centre.

His heart pounding in his chest, his lungs already burning, Mikal ran. He ran knowing the terrors that had set foot on Laghast, the sound of his fellow Jandarme dying ringing in his ears as he left the battle behind him. He could not allow himself guilt at leaving them behind; he had his orders, and the two-word message he needed to convey. Everything else was irrelevant, and so he ran.

Rotaka also ran. Though unfathomably bulkier in his power armour than the human, his superhuman constitution also made him a lot faster. He smashed straight through the door his quarry had opened manually, and landed in the long corridor. He raised his bolter and fired, but the mortal was already through the next door and the bolter shell exploded uselessly against the door frame.

Mikal heard the crash and the sound of gunfire behind him but he didn’t look back; he just ran harder. His lungs were burning and the air felt thin and hot as he panted.

He ran out of a corridor and into an atrium that linked the loading areas of the Inner Dock to the Jandarmerie. He had to swerve to the right to run around a gantry that curved around the interior wall of the atrium and led to the entrance to the next section. From the bottom of the atrium he could hear the roar of great machinery, and the air was hazy with steam.

As Mikal reached the corridor at the other end of the atrium he glanced back to see a giant figure in red-tinted armour running at tremendous speed.

Rotaka could see his target ahead, on the other side of some kind of shaft that the corridor opened out onto. The slim figure reached towards the wall, and Rotaka took a quick mental calculation of the distance between the gantries on either side of the shaft. It was hard to tell with the mist in the air, but…

Mikal, his lungs burning, slammed the emergency button next to him, and before the security shutter even dropped behind him he was turning to keep running. At the end of the next corridor was the control centre, and Commissioner Krayk. He was nearly there.

Rotaka didn’t hesitate or turn; he jumped forwards, one booted foot glancing off the handrail – his power-armoured weight buckling it with just a brief touch – to launch himself over the atrium.

As Rotaka sailed through empty space, he could hear the sound of machinery beneath him, and glanced down to see rotating gears and pistons below. Not a good thing to fall into, even for a Space Marine.

The security shutter between him and the next corridor was beginning to drop as Rotaka landed on the opposite gantry. Instead of stabilising himself to stand or run he simply let the momentum of his jump carry him into a crude forward roll, tumbling beneath the ten-inch-thick bulkhead, which scraped the ceramite on the back of his armour as he passed beneath it and rolled up into a crouch in the corridor.

Mikal was within metres of the control centre. Just through that door and, even if they shot him down before realising he wasn’t an enemy, Mikal could pass on his message, get the word out–

Rotaka, still in a crouch, swung his bolter up and fired once. The shot went low but true, missing the obvious target of the runner’s torso but hitting him in the leg, the bolt’s detonation blasting that leg off at the knee and bringing him down.

Consumed by agony as one leg disappeared beneath him, Mikal didn’t even raise his hands to stop his fall as he collapsed, and his face hit the floor beneath him, hard.

Mikal convulsed in agony, rolling onto his back. His cheek was cut and crushed, blood rolling down his face like tears, but he was in too deep shock from the pain in his leg to even notice.

Rotaka swung his bolter left and right, checking there were no other targets in range. The corridor Rotaka and his prey were in was featureless and rounded. There were no side exits, and no sign of anyone coming through the door the runner had been heading towards.

For now, he walked over to inspect his kill. Rotaka didn’t want to admit to himself how lost he had been in the moment of pursuit, that he had succumbed to bloodlust in a manner that Verbin or Malinko would approve of.

He had made a strategic judgement that the runner was important, a messenger or spy. Cutting off the enemy’s supply of information was always worth the risk.

The mortal he looked down on was barely more than a youth. His blue eyes were glassy, staring through Rotaka to some other world altogether, and he was babbling. Rotaka leaned in to hear what the dying man was saying.

‘Traitor Marines,’ he mumbled, slurring. ‘There are Traitor Marines.’

Rotaka scoffed. Was that the urgent message? The simple fact of the Red Corsairs presence?

‘I will take your message from here,’ Rotaka said, fully aware that his words wouldn’t be heard or understood in the man’s delirium. ‘Your system will know of us all, soon enough.’

Rotaka stepped around the dying man, whose breath was becoming more rapid and ragged. His death would come naturally, soon enough.

‘And do not call me traitor, mortal,’ sneered Rotaka. ‘I have known loyalty greater than a terrified whelp like you could ever imagine.’

Rotaka snapped out a brief, exasperated bark of rage, and bunched his fist ready to slam the wall, only to see the door ahead of him opening.

‘Traitors!’

The woman shouted the word in the seconds before Rotaka’s bolt shell exploded in her torso. As her body dropped Rotaka was already stepping over it into the room behind the door.

The room was a control centre with banks of cogitators and consoles, watery light from high windows breaking up the gloom of ranked servitors and adepts. Mortals opened fire on Rotaka, and he returned fire, hardly bothering to aim. Beneath the roar of gunfire, he could hear chanting, a countdown.

‘Cease fire,’ said a modulated voice, old but deep, somehow audible over everything else. ‘Let the traitor enter.’

When the las-fire died down, all that Rotaka could hear was chanting. He emerged into the room, bolter raised, ready to defend himself. No attack came. The uniformed mortals who had attacked him had gone, leaving only servitors and chanting adepts.

At the centre of the room was a control throne, turned away from Rotaka. He walked towards it, passing close to hooded adepts who visibly recoiled at his presence, and servitors that didn’t react at all.

‘Yes, closer, please,’ said the voice. ‘I am Commissioner Krayk, in command of this facility.’

Rotaka rounded the throne to find exactly what he expected: an old man in a grandiose uniform wired into a control throne. Just another old soldier with hundreds at his command, another relic of the corrupt Imperium.

‘Revolting,’ said Krayk, his eyes filled with hate. ‘I wanted to look upon a traitor before I died, and you are as vile as I would expect.’ There was a tremor in the old man’s voice as he spoke, a faltering confidence.

‘If this is an attempt to beg for your life,’ said Rotaka. ‘It is an interesting tactic.’

‘I know I am dead,’ said Krayk. ‘We’ve all been dead, ever since Sergeant Gavril – that was the woman you gunned down, Gavril – said the word traitor. I just wanted to see what such a hateful creature looks like before I died.’

Rotaka raised his bolter and indicated the adepts with the barrel.

‘What are they counting down to?’ asked Rotaka, pointing the gun back at Krayk.

‘The end,’ said Krayk. ‘A last defence against invasion – I activated it the moment I knew there were traitors in the Inner Dock. This whole island is about to explode, burying the entrance to the Pit and all of us with it.’

Rotaka swore and began to fire upon the adepts, stilling their chanting lips.

‘The chant is just ritual,’ spat Krayk, leaning forwards in his throne. ‘There is nothing and no one you can destroy to stop this now.’

‘Maybe not,’ said Rotaka, raising his bolter at Krayk once more, his finger pressing down on the trigger. ‘But it’s worth a–’

Before Rotaka could fire or complete his sentence a great roaring overcame his senses and the world turned blinding white, then dark.

The explosion tore through the Inner Dock, buildings collapsing as further explosions followed, fuel tanks igniting and power cores overloading. The cumulative explosion stretched to the very shore of the island on which the dock had been constructed.

The causeway that stretched from the island to the mainland, and which was the main transport link from the dock to the rest of Laghast, was caught by the edge of the explosion. Lastrati were still trying to escape via the causeway, either on foot or by grabbing on to the train that had partially departed the station, and those nearest the island were consumed by flame.

The intense heat and aftershocks from the explosion created cracks in the causeway, and the structure began to crumble, falling down from where the station lay in ruins, the damage spreading out to sea as the causeway’s superstructure was undermined.

The collapse did not spread very far, but far enough to catch the end of that last train, the rails beneath the final carriage falling into the sea as the causeway disappeared beneath it, burning rubble sinking beneath the waves. The unsupported rails buckled and bent, and the train tried to move away, to pull its final carriage up to safety.

There was a moment of teetering, then the end carriage fell into the sea, dragging the rest of the train behind it. Hundreds of Lastrati had packed into the carriages and cargo holds of the train, and as it slowly slid off the causeway they tried to escape via windows and doors. Few managed – to allow the high speeds required to quickly travel to the mainland, the train environmentally sealed itself on departure.

Being airtight, the vehicle was also soundproof, and no screams could be heard as the train sank to the bottom of the ocean, nearly a thousand souls of the Imperium on board.

The area Rotaka had been in when the explosion tore through the Inner Dock had only partially been destroyed in the blast, and it was simple enough to push aside the rubble and dig himself out. He climbed out to a scene of carnage, an island strewn with blazing rubble, half-broken walls emerging from the debris like jagged teeth.

If the Lastrati had thought destroying the dock in such a way would kill the Red Corsairs, then they obviously knew nothing about Space Marines. As he looked around, Rotaka could see many others climbing out of the wreckage. The blast had been low impact, and mainly incendiary – it had wrecked the infrastructure, but barely scratched power armour.

Rotaka could see a towering figure standing on the burning shore, looking out to sea.

Issuing an order to his squad to dig themselves out and put themselves in order, Rotaka left them to it and walked towards his lord.

As he approached Huron Blackheart, Rotaka looked out at the inverted world, the curved sea. Behind the artificial sun, the other side of the world was in night-time, a constellation of lights indicating the inhabited areas against a dark blue.

‘My lord,’ Rotaka said as he approached Huron, whose claw was reflexively opening and closing as he stared out to sea. Behind him he could hear shouts and crashes as the other Red Corsairs dragged themselves from the wreckage, but Rotaka paid them no mind. Blackheart’s presence, that aura of malevolent command, drew him forwards.

‘Look at it, Rotaka,’ said Huron Blackheart, holding out the Tyrant’s Claw, palm open. The deathly grey of his remaining skin looked incongruous in this environment, the restless sea and the harsh light from the artificial sun. ‘The first Hollow World, mine for the taking. And soon the rest.’

‘And then, my lord?’ asked Rotaka.

‘And then,’ said Huron, lifting the claw up so that it blocked his view of the sun, then clenching it shut as if squeezing the life out of the sun itself. ‘Then, we make a hell of these worlds.’

Seven

The base of operations Colonel Ruthger had earmarked for retaking the city was Eridano’s central Jandarmerie, a squat, heavily fortified garrison in the very centre of the city. It fulfilled Pranix’s requirements as a defensible position to occupy when it became clear the enemies who were tearing the city apart, covered in bloody symbols and driven insane by the bugs in their heads, were never going to give up.

‘And still they come,’ said Pranix.

He and Kretschman were standing on top of the Jandarmerie, looking down. Around the edge of the roof, mounted guns pointed down at street level, manned by two-man crews, barrels blazing as they fired into the crowd below.

Night was falling, but as the light faded the other side of the world could still be seen, a vast ocean with a mass of light at its centre. Not the distinctive glow of city lights, but a fierce orange-and-red light speckled with black smoke that trailed out across the ocean.

It was an island aflame, an inferno big enough to be seen at the other side of the world. Looking up was enough to have Kretschman silently reciting his mantra to keep calm, and the sight of a major landmass on fire made the ground lurch beneath his feet. He had never seen destruction on such a scale, from such a distance.

He pointed to the burning island. He intended to ask a nearby Lastrati what the land mass was, but his mouth was dry and the question didn’t come.

‘It’s the Inner Dock,’ said Pranix without being asked, the inquisitor’s eyes locked on the distant fires. ‘You can see the causeway leading to the main continent, though it seems to have been partially destroyed.’

The inquisitor’s voice was eerily calm considering the scale of what they were witnessing.

‘The causeway,’ repeated Pranix. ‘Don’t you remember the briefings from when your regiment arrived here?’

‘No, my lord,’ said Kretschman. It sounded like the sort of thing he should remember, but he couldn’t.

Pranix looked sideways at Kretschman. ‘Well, sergeant,’ said the inquisitor. ‘The Hellward Gate is the Maelstrom-facing entrance to the Hollow Worlds. And while it could have been sabotaged from within, I suspect it is far more likely that it has been invaded from without.’

‘Invaded?’ said Kretschman. He was dimly aware that he shouldn’t be trying to interrogate an inquisitor, but his head was fuzzy. ‘Who by?’

Pranix looked at him sharply. ‘That’s exactly what I intend to find out,’ he replied.

The corvid flew over the crimson forests of Ressial, stopping neither for food nor for rest. It did not need such things: its stomach and digestive systems had been replaced with a tiny generator that removed the need for any other sustenance. The purplish-black feathers of the bird were augmented by a brass skullcap, streamlined so as not to slow its flight.

The birds of the Hollow Worlds were the only things that could fly within the system, some natural instinct preventing them from flying too high and falling into the sun. Instead they travelled the highest air currents, just below the level of gravitational shift.

They were a natural wonder, although in the instance of this corvid and many like it, nature had been adapted to the needs of the Imperium of Man.

The corvid flew lower as it went over the glittering rooftops of the Onyx Palace and the lush excess of its many gardens. It swooped around the statuary of the Gatehouse, towards a cathedra just outside the grounds. The corvid squawked recognition at the spires of the cathedra and looped down, towards the flat central roof area between the spires and other gothic ornamentation of the Ecclesiarchy.

At one end of the roof there were coops and perches, and the corvid landed on one such perch, cawing for attention.

A robed figure, weighed heavy with penitential chains, shuffled across the rooftop and attached two loose copper wires to the corvid’s chest. As the bird recharged, a sliver of vellum emerged from a narrow slot on its chest.

‘Another message for Lord Cheng,’ said the hooded figure and rang for a servant to take the message to its recipient.

Lord Dumas Cheng, system governor of the Hollow Worlds, had been unaware of the existence of the corvids until an hour earlier. The High Priest of the Ecclesiarchy within the Hollow Worlds, having been informed of the deepening crisis, had revealed that the Ecclesiarchy had – and had always had – a secret form of communication, for the purposes of their own internal machinations.

For once, Cheng had reason to be grateful for the duplicity of the Ecclesiarchy. Only a few hours since losing comms, Cheng had been able to send a message out to the other worlds, bypassing the corrupted systems altogether. It was far slower than standard channels, but it worked.

He awaited a reply irritably, sitting on the throne in his control room in the Gatehouse.

‘My lord,’ said a heavily augmented, red-robed figure, approaching Cheng’s throne slowly.

‘Chief Adept,’ Cheng replied. ‘You honour us with your presence. Do you bring good news?’

The Chief Adept, most senior of the Adeptus Mechanicus in the system, made a fluttering noise with the brass gills in his neck, his equivalent of a ‘hmmm’.

‘We believe the communication failure is system wide,’ said the Chief Adept. ‘We have also identified its source.’

Cheng waited expectantly for more information.

‘Heresy,’ said the Chief Adept. ‘Foulest heresy, infecting the sacred code. It corrupted several of the adepts who looked upon it, and I had to have them executed to prevent it spreading further.’

Cheng slumped back in his throne. Heresy on the Hollow Worlds? It was unthinkable.

He had barely begun to process this news when a monk of the Ecclesiarchy ran into the throne room, breathless. He stopped and gave a hasty bow to Cheng, then another to the Chief Adept, who tilted his head quizzically.

‘If the message is urgent, it is urgent,’ said Cheng. ‘Stand on no further ceremony.’

‘It is from Laghast, my lord,’ said the monk, then read from a tiny piece of vellum: ‘Hellward incursion astropathic tower fallen inner dock destroyed.’

Eight words. That was the whole message.

Dumas Cheng dismissed the monk and begged leave of the Chief Adept. Surrounded only by servitors and underlings, he concentrated on what he knew.

If this incursion was connected to the unrest and the loss of communications – and Cheng would have to be a fool to hope otherwise – then the invaders would have an easy route through Laghast, and from there to Kerresh.

Then from Kerresh to the rest of the system.

Laghast was a world of millions of souls, the gateway to the Hollow Worlds. At least one regiment of Lastrati Guard, along with a Cadian regiment, were stationed there.

Two Imperial Guard regiments were a strong counter to most threats. Supported by the Jandarme, with reinforcements from the inner worlds, they should be able to drive out any invasion.

And yet… the Hellward Gate faced out towards the Maelstrom, where resided some of the most terrifying enemies not just of man and the Emperor of humanity, but of all life. Whoever was attacking had sown dissent through the Hollow Worlds, taken down their communications, and already broken through powerful orbital defences and the forces within the docks. Then there was the Chief Adept’s use of the dreaded word: heresy.

Dumas Cheng was not an ordinary subject of the Emperor, living in ignorance of heretical threats. This was an attack by the forces of Chaos. Emperor knew what monstrosities were flowing into Laghast already.

No, he could not risk the fall of the Hollow Worlds. The safest course was to isolate the infection. He would allow as much time as he could for evacuation, and to gather further intelligence… but he needed to cut off Laghast as soon as possible, to allow the other worlds time to prepare defences.

‘Send the order,’ he told a messenger. ‘If an enemy gets within sight of the Laghast Archway, destroy the gateway before they set foot on Kerreshian soil.’

The messenger ran off. Dumas Cheng stared into space. He might have condemned a whole world to a terrifying fate.

As the great girder was lifted away, the man crushed beneath it spluttered and took in ragged breaths. In the two days since the explosion had torn through the Inner Dock, this mortal had been trapped in a narrow space within the ruins, limbs crushed but with enough room to breathe. After so long in darkness he stared blindly up at the towering figures looking down on him, muttering thanks to his saviours through parched lips.

‘It is miraculous this one has survived,’ said Hulpin.

‘Not the word I would have used,’ said Rotaka, looking down at the broken mortal. He took no satisfaction in suffering, even of lesser creatures such as these. ‘Verbin?’

Verbin nodded with a grunt, stepped down to where the broken man lay, and stamped on his chest, killing him instantly.

The impact of Verbin’s stamp damaged more than the dying mortal – the slab the mortal had been lying on broke in two, and both Verbin and the corpse disappeared into a hole in a shower of dust.

‘Now that’s my idea of a miracle,’ said Malinko.

Rotaka was about to tell Malinko to hold his tongue when Verbin’s voice came from the hole. ‘I’ve found it!’ It appeared he hadn’t fallen far.

‘Stay there,’ said Rotaka, then he turned to Malinko, Wuhrsk and Hulpin. ‘Keep clearing. I’ll fetch Valthex.’

There were low grumbles of protest but Rotaka ignored them as he walked away, his boots sinking into the scree as he climbed a hill of rubble. They had reason to complain – they were Space Marines, Red Corsairs, doing the work of slaves and servitors. But while Huron Blackheart’s army deployed from the Pit, he had ordered his Corsairs to search the debris for possible sources of intelligence.

And so the Corsairs picked through the wreckage. If it was demeaning, then Lord Huron had the right to demean them. They were merely an extension of his will.

From the top of the hill, Rotaka could see the whole island. The first slaves to be brought through to the surface were clearing the area around the pit, hundreds of humans toiling beneath the artificial sun to make way for Huron’s army, to create an open area for Huron to marshal his vehicles.

Those vehicles had begun to emerge: Rhinos, Predators, Vindicators, Defilers… even a flat-bedded transport carrying a colossal, chained and secured box from which periodic crashes could be heard. Countless vehicles lined up away from the Pit, which was now exposed to the air, a giant hole in the centre of the island, and in the very skin of the world.

Cranes salvaged from the rubble leaned over the Pit, creaking with strain as they pulled gigantic chains, slowly hauling something huge out of the Pit.

Remembering his mission, Rotaka tore his eyes away from the spectacle and looked out across the island. He could see pockets of Red Corsairs searching the wreckage, others duelling or shooting targets, but no Valthex.

Rotaka had kept Iltz inactive, tied within a bag of cured skin strapped to the back of his armour. He loosened the crude strings that held the bag together, and pulled out the servo-skull. It floated into the air, its shroud of blue flame emerging but barely visible in the sunlight.

‘Find Valthex,’ Rotaka said. ‘Give him my coordinates.’

As Iltz drifted away Rotaka returned his attention to the Pit. The chains and cranes were nearly done, their burden emerging. The first of Huron Blackheart’s galleons, the Unyielding Fist, rolled out onto the surface of Laghast.

Each had once been a Capitol Imperialis, but centuries in the Maelstrom had changed their form so that only a rough outline of the vehicle’s original shape could be seen. The first to emerge occupied almost the whole diameter of the shaft, its rough-hewn tracked wheels clawing up the walls of the pit. When it reached the top, as well as the cranes, armies of slaves used their chains to pull the galleon from the hole.

When the galleon emerged, it continued to roll, crushing the massed wreckage of broken and burning buildings under its great tracks. Rotaka looked at the malevolent machine, a towering ship of blackest metal, the spectres of lost souls briefly visible in the ooze that slicked its sides. Barnacled portholes looked out from its sides, while a gigantic skull stared from its prow.

It was an ancient, mutated thing, a machine of war that had become something not quite alive and not quite dead. In the bright sunlight of Laghast, it seemed to drink the light into its own impenetrable darkness, squatting like a malevolent presence.

He was very glad that these vehicles were on his side.

‘Rotaka,’ said Techmarine Valthex, breaking his chain of thought. ‘You wanted me?’

‘This way,’ said Rotaka, leading the Techmarine down to the hole. Iltz resumed floating a short distance behind Rotaka, drifting along at shoulder level.

Hulpin, Malinko and Wuhrsk had cleared the rest of the shattered ceiling away, giving easier access to the room below.

Valthex dropped down into the chamber to inspect what Verbin had found, what Rotaka’s squad had been assigned to find: a row of intact, albeit powerless, communications cogitators.

‘Yes,’ said Valthex, brushing a scattering of dust and shrapnel from the top of one of the cogitators. ‘This is exactly what I need.’

‘Some of these rungs are loose,’ Pranix told Kretschman, who was climbing ahead of him. ‘Be careful, I can’t afford to lose that equipment.’

It might have occurred to someone other than the inquisitor that Kretschman’s death might be a better incentive to take care than the loss of the equipment, but Kretschman was just glad of the warning, testing each rung before putting any weight on it. The equipment in the bag on his back made him heavier than usual, and his limbs ached as he climbed.

The ladder was attached to the side of a communications tower at the edge of Eridano. Colonel Ruthger had shown a flash of reluctance to secure a comms tower on the edge of the city while many more obviously strategic locations were yet to be taken back from the mob, especially as the comms were still corrupted.

‘The main comms system is corrupted,’ Pranix had said. ‘A sound tactical manoeuvre, to disrupt communications. Fortunately, alongside the Imperium’s conventional communication systems lies another, well-hidden network, considerably harder to access and disrupt. Get me to that comms tower and I can access it.’

Before Ruthger had even resignedly agreed, Pranix had opened his mouth to make another request: ‘I’ll also need someone to carry heavy equipment.’

Which was how Kretschman found himself climbing the comms tower. He paused to take a breath and looked out across the city: fires still burned in hab blocks, smoke rising from gutted buildings. The initial disruption seemed to have unleashed buried tensions in the city, cults and rebel groups forming everywhere, leaving the Jandarme and the Guard to retake the city block by block.

‘We’re nearly there,’ shouted Pranix from above. ‘Not far now.’

Kretschman resumed the climb, and shortly found himself stepping out onto a rusty platform with an equally rusty box in the centre.

‘Sergeant?’ Pranix indicated the box.

Nodding, still breathless from the climb, Kretschman set down his pack, removed a long multitool from the side pocket and walked over to the box. A panel was fixed tightly to the front of the box, but there was enough space around the edges for Kretschman to get the end of the tool in there. A little levering and the panel fell away, revealing blinking equipment within.

‘Thank you, sergeant,’ said Pranix. ‘Once again you prove the ideal tool for the job.’

Rotaka watched as Valthex restored power to the communications cogitator, then extruded connecting cables from the rig on his shoulders to the cogitator. ‘The scrapcode within the enemy’s comms system does not simply disrupt, it also filters and collects,’ Valthex said, tapping at runes on the cogitator.

‘Collects what?’ asked Malinko. Having been tasked to find this chunk of Imperial junk, Rotaka’s squad had gathered around to see what Valthex did with it.

‘Intelligence,’ said a voice from above; a long shadow cast over them all.

‘My lord,’ said Rotaka, kneeling and bowing his head. His squad did the same as Huron Blackheart dropped into the room with them with a crunch.

‘Troop movements, distress calls, evacuation orders,’ Huron said, ignoring Rotaka’s genuflection. He strode amongst them purposefully, his movements tight, suggesting the violence and rage that could be unleashed on his subordinates at any time. ‘Advance intelligence will hasten the crushing of my enemies. Rise.’

Rotaka did so. He could feel the unease within his squad at being so close to the Blackheart in such a confined space. Huron’s presence eclipsed them all.

Valthex had neither bowed nor responded to Huron, a suicidal action for most. Instead he remained in position by the cogitator, looking at data on the internal display of his helmet.

‘Valthex,’ said Huron, a note of warning not to disappoint in the way he spat the name. ‘What information do you have for me?’

‘There’s another presence in the communications system,’ said Valthex, distantly, still concentrating.

‘You promised me the Lastrati communications would be utterly disrupted, Valthex,’ said Huron, his voice low and dangerous.

‘They are,’ said Valthex, unfazed. ‘This isn’t the conventional communications network, which is still completely under the control of our scrapcode. This is another network, overlapping the one we have control of. Someone is using it to interrogate the system from outside.’

‘What network?’ shouted Huron. ‘Who would dare?’

‘The Inquisitorial monitoring sub-network,’ said Pranix, his face glowing in the green light from the screen of the equipment he had produced from Kretschman’s bag. ‘It usually filters relevant information and copies it to… Well, you don’t need to know, but I’m using it to dig into the corrupted network.’

Kretschman didn’t know what Pranix was talking about, except that it seemed to mean the Inquisition were always watching, always listening. He pulled the collar of his uniform jacket up – this high up harsh winds battered the exposed platform they stood on, and as night began to fall those winds were getting colder.

‘Visual feeds,’ said Pranix after a minute or so of silent concentration. ‘Visual feeds from the Inner Dock, logged with a very recent timestamp.’

He seemed barely aware of Kretschman’s presence now, talking to himself at the same speed as his fingers danced across the runes. Kretschman moved around the platform until he could see what was on screen, but all he could make out was a blur of motion and flashes of light.

‘Let’s clean this up and see who you are,’ said Pranix, and the image began to slowly resolve. It showed three bulky, armoured figures firing weapons and lashing out at members of the Jandarme. Kretschman flinched as one of the giants picked up a Jandarme by the throat and snapped his neck, tossing the body aside. Then the image whited out and returned to the start of the sequence, and this time Kretschman could clearly see what was going on – three armoured giants, painted with grotesque sigils and strewn with macabre totems, massacring human beings with bolters and fists.

Pranix swore, an exceptionally filthy phrase in a lowly worker’s slang.

‘Traitor Marines,’ said Pranix. ‘Red Corsairs, judging by the markings on that armour.’

The phrase chilled Kretschman to the core.

‘I’ve seen enough,’ said Pranix, pulling the cable connecting his equipment to the cogitator. The screen went blank.

‘Did you recognise those traitors, sergeant?’ Pranix asked, locking his eyes on Kretschman’s.

‘No, my lord,’ he replied.

Pranix paused, watching Kretschman closely, before continuing. ‘I did not expect you to – the existence of Traitor Marines is forbidden knowledge. If you had recognised the Red Corsairs, sergeant, you would know that your regiment, and the forces of the Lastrati, have no chance of stopping them,’ said Pranix, hurriedly repacking his equipment into the bag and then throwing it at Kretschman. ‘A force will need to be summoned to drive them out, a strike force capable of dealing with traitors of this power.’

‘Summoned, my lord?’ asked Kretschman.

‘Summoned, in person,’ said Pranix. ‘Only an inquisitor has the authority to disrupt existing orders like this, and with the Astropathic Tower destroyed there is no chance of sending out a summons from within the Hollow Worlds. I will need to locate the nearest warzone and return in force.’

‘I need to get out of this system as fast as I can, sergeant,’ said the inquisitor.

Rotaka watched Valthex clench and unclench his fist. This gesture of frustration was as close as he had ever seen the Techmarine come to displaying an emotion.

‘Gone,’ said Valthex. ‘They’ve gone. The connection has been broken before I could trace–’

Whatever the Techmarine was about to say, it was cut off by an incredible roar of anger from Huron Blackheart, who swung around to knock over a half-fallen wall with the Tyrant’s Claw, chunks of masonry ricocheting in all directions.

‘I do not like uncertainties, Valthex,’ snarled Huron. ‘If there are parties at work here unaccounted for in my plans–’

‘This other network,’ said Valthex. ‘To outwit the scrapcode… Only someone – or an organisation – with the highest level of access could–’

‘The Inquisition!’ sneered Huron, saliva dripping down his chin as his face twisted with hatred. ‘An inquisitor in the Hollow Worlds could cause disruption. No matter, I will have this Imperial lapdog found and torn to pieces before he can cause difficulties. My conquest of these worlds will not falter.’

Colonel Ruthger liked an ordered military existence. The presence of mysterious invaders and inquisitors disrupted this simplicity, so a representative of the Ecclesiarchy seeking an audience with him initially felt like the third of a bad trio. Nonetheless the Ecclesiarchy were a powerful ally, and it was not sensible to antagonise them, so Ruthger ordered Rothke to show this Brother Arashan into the briefing room that Ruthger had commandeered as his base of operations. Arashan was a tall, thin man with olive skin and a short, fiercely white beard. He gathered his robes around him as he came through the door.

‘Colonel Ruthger,’ said Arashan, his elaborate headdress teetering as he gave a slight bow. ‘It is fortunate we have a Cadian regiment on our world in such a troubling time. Order is already being reasserted on these streets, thanks to your enlightened leadership.’

Ruthger returned the nod and uttered some formal pleasantries.

‘I come here not to represent my own order, but as a messenger,’ said Arashan. ‘The system governor has made contact.’

Arashan explained the Ecclesiarchy’s corvids. Ruthger appreciated the ingenuity, and was unsurprised that the Ecclesiarchy should maintain a secret communication network of their own.

‘System Governor Cheng believes the enemy will wish to seize the Archway that allows transit between Laghast and Kerresh as soon as possible,’ Arashan said. ‘The most direct route requires the conquest of the coastal factorum city of Nulstrom, but without knowing the identity of these attackers–’

‘Traitor Marines of the Red Corsairs,’ said Inquisitor Pranix, walking into the room as if he had been part of the conversation all along.

Pranix flashed his hololithic identification in Arashan’s direction and the priest gave the inquisitor a deep bow.

‘Is that even possible?’ asked Ruthger. Traitor Space Marines? Space Marines were demigods, the Emperor’s finest, the only warriors Cadians looked up to. How could any be traitors? It was unthinkable.

‘There are many heresies mankind is not equipped to know about,’ said Pranix. ‘Suffice to say this is a very grave threat.’

‘The system governor wishes to keep the Archway to Kerresh open a few more days, to allow evacuation,’ said Arashan. ‘Would you counsel that it be closed immediately, my lord inquisitor?’

Pranix said nothing for half a minute.

Ruthger and Arashan exchanged glances, but then the inquisitor spoke.

‘No,’ he said, finally. ‘We should take the chance to deny the enemy any further resources. Set up two lines of defence, at Nulstrom and around the Archway, make them fight for every step, but then withdraw your regiment, colonel, and prepare Kerresh for invasion. Huron Blackheart is master of the Red Corsairs – whether through sorcery or technology, he will break through to Kerresh eventually.’

Ruthger licked his dry lips. Traitor Marines, this Blackheart person and sorcery? His world was becoming further complicated by the second.

‘Will you give me your counsel, lord inquisitor?’ asked Ruthger.

‘Will I lead you, do you mean?’ asked Pranix bluntly. ‘No, I’m going elsewhere.’

‘To the inner worlds, my lord?’ asked Arashan. ‘If so I may acco–’

‘No, no, I go alone, north,’ said Pranix. ‘To the mountains.’

Eight

Three nights later and an ocean away, the coastal city of Nulstrom had prepared as best it could for invasion. Nulstrom was the gateway to Laghast’s main continent, a port city built at the very edge of the landmass, the outer walls of the city’s hives providing a barrier of human lives as well as rockcrete against any invasion. Lissica had grown up in one of those windowless habs, her life underscored by the distant boom of waves crashing against the walls.

So Lissica and her fellow Jandarme of the Coastal Watch, along with any citizen who could fight or help build further defences, had spent three days working to prepare.

The wind coming off the sea was bitterly cold, cutting through Lissica’s uniform and through to her bones. She kept watch nonetheless, raising a telescope in shaking hands to look out to sea. There was not much to see. The darkness was almost total, a dim, glistening reflection of the daylit continents on the other side of the world rippling on the water’s surface.

When Lissica caught sight of something large out there, she wasn’t at first sure that her frozen brain wasn’t playing tricks on her. She moved her telescope around to check she was not just looking at the broken causeway – but no, there it was, stretching out into the distance, a black strip that ended in collapse somewhere out of sight.

She turned back to the mysterious shape. There were two of them now. Distances were hard to judge, at sea and at night, but they seemed to be tall, bulky things, floating towards the shore.

‘Trakhanov!’ she shouted, and pointed out to sea.

An older man, Lissica’s superior, ran forwards and raised a pair of magnoculars to his eyes. ‘I see them too,’ he said. The shifting darkness could easily cause a jumpy sentry to raise a false alarm, so all sightings needed a second opinion.

Lissica froze, paralysed by the enormity of what was happening.

‘Well?’ shouted Trakhanov. ‘What are you waiting for? Light the beacon, I’ll sound the alarum.’

Lissica ran across the rooftop to where a pile of salvaged junk from within the habs had been piled high. There was a harsh smell of cheap accelerant from the pile, and she kept her distance as she lit a match and tossed it on.

The signal fire burned high and fast, but the crackling of the flames was drowned out by the plaintive wail of Trakhanov hand-cranking the alarum.

Shouting could be heard in response to the alarum, and as Lissica looked across to the next block she saw another huge fire appear, then another in the distance.

The alarm had been raised and answered. Nulstrom was waking to war.

‘There!’ hissed Huron Blackheart as a line of fires appeared in the distance. ‘The city awakes.’

Garreon had been alongside Huron for most of the voyage across darkened seas. The Tyrant had prowled the deck of his personal galleon, the Unyielding Fist, throughout that time, looming over the mutated crew, the overwhelming power of his presence making the open space seem cramped.

The galleons were hulking vessels of oily black metal, propellers at the rear churning beneath the water to move them. Every surface of the Fist seemed oily, blackened, decayed, as if the galleon had been pulled from the depths of the ocean only seconds before. Huron had ordered all lights extinguished so as to approach the coast by stealth, and the deck was a glistening surface disrupted by the huddled shapes of gun batteries and equipment.

‘Give the order,’ Huron told Garreon, not moving his eyes from the distant fires. ‘Light the fleet and strike fear into these mortals.’

Garreon nodded, and strode towards the bridge where the mortal, corrupted crew of the Unyielding Fist piloted the ship.

‘Captain,’ Garreon called out. ‘Vox all ships. Light the decks, fire on coastal defences at will.’

‘Aye, my lord,’ said the captain, an elderly mortal in a uniform streaked with red.

As the captain relayed the order, Garreon turned on his heel and returned to Huron’s side. All around him, gaslights spluttered into life, illuminating the deck with a sickly green flame. The torches were fed from pockets of poisonous, flammable gas somewhere deep below decks, and Huron seemed even taller and more menacing lit by the eerie glow.

Garreon could hear the great cannon mounted on the deck begin to grind into action, slaves sweating to turn the wheel that rotated the huge weapon. Out of the silence came a babble of voices in a dozen languages, mutated creatures driving the slaves, passing on orders issued by the Red Corsairs controlling the targeting.

Pallid, corpse-like humans, some mutated with crab claws and scales, slaving under the whip of bestial gangmasters, manned the smaller gun batteries on the foredeck.

Huron turned to the Corpsemaster, one side of his mouth twisted up in an insane smile. ‘Now they’ll see what nightmare comes for them.’

They were like no ships Lissica had seen in a life lived on the coast. In response to the watch-fires burning across Nulstrom, the barely visible ships had lit themselves up, or set themselves ablaze, or… Lissica wasn’t sure, but they burned with an unearthly green glow, a fleet of hulking vessels advancing on the shore.

‘Emperor save us,’ said Trakhanov. ‘Emperor save us all.’

Lissica looked across to him. The motivation he’d had a few minutes ago seemed to have drained out of him. ‘Let’s not throw ourselves on the Emperor’s mercy just yet,’ she said firmly.

Trakhanov looked at her blankly, only to jump in shock as the coastal defences opened fire.

Five giant defensive lascannons were embedded in turrets across the coast. The nearest to Lissica and Trakhanov’s position was on the next rooftop, and as it fired the night was briefly day again, and the sound of the shot smacked into Lissica’s chest like a physical blow.

The galleons began defensive manoeuvres the moment the giant lascannons on the shore began firing. On the deck of the Unyielding Fist cogs ground and orders were shouted as the weaponry on deck was brought to bear on the massive guns. Garreon shifted his weight to compensate as the ship turned, bracing himself as the deck tilted beneath his boots.

The Fist shook as a las-shot caught its hull, the air to port filling with steam as most of the blast hit the sea, vaporising a mass of water.

‘Too close, captain!’ roared Huron Blackheart, but his warning was drowned out as the gun batteries of the Fist opened fire.

Garreon watched the streaks of fire from the gun batteries as they arced towards the coast. Then he felt something heavy clamp down on his shoulder, a colossal pressure even through his power armour. His eyes snapped back to find Huron Blackheart staring at him, organic eye twitching, the Tyrant’s Claw gripping Garreon’s pauldron.

It took incredible effort for the Corpsemaster, who had brought nightmares and torments to so many, who revelled in despair, not to flinch.

‘Give this order…’ hissed Huron Blackheart.

The response from the fleet out at sea was an unholy roar of weaponry, and while each shot from the coastal defences was a thunderous report, the retaliation was instead the cacophony of many, many smaller weapons firing at once. The sky lit up again as fiery points of light arced high into the air while beams of las-fire criss-crossed the space between the galleons and the coast.

From where Lissica stood she could not see where on the walls the las-fire had impacted, and she moved to run towards the rooftop’s edge, to look over the lip and assess the damage to the coastal wall, but Trakhanov caught her elbow.

‘Are you insane?’ he shouted. ‘We need to get back from–’

His words were drowned out as one of the glowing shapes that had arced up into the sky from the galleons hit the other side of the rooftop Trakhanov and Lissica were standing on. The impact whiplashed up Lissica’s spine as she and Trakhanov were thrown off their feet, a ball of fire and shattered masonry spewing upwards from the point of impact.

Blinking, deafened, aching, Lissica tried to force herself back up again, and she didn’t know whether the shifting feeling beneath her was real or the result of concussion.

Trakhanov helped her up. He was pointing to the nearby lascannon on the next roof, indicating they should go to it. It made sense; the heavy weapon was surrounded by a cluster of bunker-like structures, and they might prove more useful there, and be more protected.

Lissica glanced across the city and saw habs and factories ablaze, shells continuing to rain down. Then the assault stopped.

Fire from the sea had battered the walls, and the rockcrete beneath their feet was scorched black. There was a sickly smell of burning in the air, and Lissica didn’t look too closely at the charred, slumped forms of the many dead Jandarme.

A single survivor, half his face horribly reddened, one eye closed and weeping, was trying to pull a mortar into position, even though his left arm was limp and clearly broken.

‘Help me,’ said Trakhanov, and Lissica joined him in moving the heavy barrel into place.

‘We need to be ready,’ said the wounded man. His relatively good eye looked unfocused, and Lissica wasn’t even sure he could see any more. ‘For when they come back.’

She thought he was blind, or had just gone mad, but when she looked through the gap in the wall she realised what the wounded man meant – the enemy ships had put out their lights, and the smoke from the battle hung over the sea, obscuring the view.

To all intents and purposes, the enemy ships were invisible.

‘Lord Huron,’ said Garreon. ‘All ships report their main cannons are targeting coastal defences. If we wait we risk expo–’

‘Hold fire,’ Huron snapped back, and Garreon knew from his tone that it would be very, very dangerous to dispute the order. ‘We are not close enough.’

The galleons were drifting silently through the darkness and smoke, mortal crew spluttering and coughing as they worked. The bombardment of the coast had set much of the city ablaze, and even through the smoke the gun placements high on the coastal walls were clearly visible, silhouetted by flame. A great clanking and grinding could be heard on the deck of the Fist as slaves used chains to adjust the barrel of the galleon’s most powerful weapon, a huge gun capable of firing monstrous shells. As the Fist and the other galleons moved towards the coast, the large guns would be adjusted to keep targeting those defences.

To hold fire was a risk – while closer proximity to the targets would enable a surer shot and greater damage, any adjustment to such large guns was difficult, subtle adjustments near impossible.

‘Hold, hold,’ said Huron, slowly raising the Tyrant’s Claw. Then he brought it down in a slashing motion.

‘Fire!’ he shouted, a terrifying roar that carried over even the screaming gears as the giant gun barrel continued to move.

The order was meant for the whole of the fleet, but it was the great gun on the Fist that fired first, the report of the shot so great that the sound of it felt like a blow.

The shot reached its mark and one of the coastal towers exploded in a burst of promethium, the coastal wall beneath it collapsing as the explosion tore solid rockcrete to pieces and the shock wave spread through the entire structure.

‘We’ve lost a tower!’ someone screamed, but Lissica didn’t need to be told. Although she could not see the destruction from her position at the base of one of the five huge lascannons, she heard the explosion, saw the sky light up, and felt the collapse of part of the coastal wall through her boots.

‘In the Emperor’s name,’ said Trakhanov. ‘They’re nearly under us.’

Trakhanov was right; the enemy ships were now visible again, the large guns on their decks firing on the towers, smaller gun batteries blazing at the coastal wall. They could be targeted now, but they were close – so close that they would soon be past the point where the lascannons could target them from their high position.

There were ragged cheers from the crew of the Fist as the third tower fell, cut off abruptly when a shot from one of the two surviving lascannons hit the hull of the Whip Hand. As the other galleon capsized, foul liquid spreading around it as the ruptured promethium tanks leaked into the sea, Huron Blackheart batted Garreon aside to take matters into his own hands.

As he marched to the rear of the deck, Blackheart shouted up to the bridge: ‘That tower is mine. Vox all galleons to target the other tower, but leave that one to me.’

Across the fleet, gun batteries and small cannon were firing, but the largest guns were silent. The giant cannons, the barrels of which were half as long as the decks of the galleons that carried them, took many minutes to reload and move into position for another shot.

Garreon was right behind Huron as he descended upon the dozen slaves who were dragging a trolley carrying a giant shell into position.

‘Ready the chamber!’ yelled Huron, backhanding three of the slaves out of the way. One was caught under the jaw by the blow and didn’t get up again, the mortal’s head twisted back at an unnatural angle. Huron stepped over the corpse, kicking it aside.

There was a distant explosion and cheers, presumably the fall of the fourth tower, but Huron was preoccupied. With a grimace of exertion he gripped the shell, which was almost as tall as he was, and lifted it to shoulder height. Slaves were heaving open the round, rusty hatch that gave access to the gun’s chamber as Huron stepped across to it, each step a struggle against the tremendous weight bearing down on him.

With a final grunt Huron tipped the shell over and it crashed into the chamber. Slaves rushed to close the hatch. ‘Fire in five,’ he ordered.

‘But, my lord, we have not adjusted the–’ began a mortal officer, but Huron gave him a glare that caused the human to step backwards.

‘Fire in five,’ said Huron. ‘Leave the targeting to me.’

‘My lord,’ said the officer weakly. ‘Begin launch. Firing in five…’

Garreon had seen the slow movement of gears and pulleys that moved the gun into position to aim at a target. Huron ignored this equipment, smashing one of the chains and kicking the barrel of the cannon.

It didn’t move.

‘Four.’

‘Garreon,’ said Huron as he shoulder-slammed into the barrel. It moved very slightly, a shower of coppery rust falling off the gears.

‘My lord,’ said Garreon, rushing to Huron’s side to join him in the next push.

‘Three.’

The Tyrant and the Corpsemaster slammed into the side of the gun and the barrel moved with a screeching of metal. Looking down the length of the barrel Garreon could see it was almost aligned.

‘Two.’

‘Again,’ said Huron and they charged the barrel, and it moved once more, the shock of the blow vibrating through Garreon’s armour.

Huron was now under the barrel, pushing upwards, trying to lift it to better target the cannon on the tower.

‘One.’

Garreon moved to assist his master but it was too late; the gun was about to–

‘Fire!’

The galleons were close enough now that Lissica was deafened by the blast from the enemy ship, its great gun firing a shell straight at her position. Trakhanov and Lissica fell to the rooftop, shaken off their feet by the impact. Lissica knew they were at the foot of the last of the big guns defending Nulstrom, that they were the last major target.

Flat on her back, body still shaking, Lissica looked up at the lascannon. It still stood, the barrel aiming out to sea. Had the enemy missed? If so she and Trakhanov needed to get on their feet, to get the gun and–

Everything began to slide. The rooftop she lay on was crumbling, and as she looked up the cannon began to lurch to one side, the whole structure unstable as the rooftop beneath it fell away.

They hadn’t missed. Whatever weapon those monstrous ships wielded had torn the block beneath them to pieces, ripping apart the hab and the factorum and all of the rest. The walls were falling, the defences were down and Lissica was falling with it.

She fell, tumbling downwards in a torrent of broken rubble as the building collapsed, and the colliding chunks of debris broke her body and killed her long before it reached the sea and sank to the bottom.

Lissica’s last thoughts, in painful darkness, were not of herself but the fact that Nulstrom had fallen.

Rotaka picked up a handful of loose gravel from the ground. He rolled the burned fragments of stone and rockcrete around his palm with his thumb, then poured it out of his hand. The lighter fragments were caught by a wind from the sea and blown away; the heavier chunks fell to the ground, lost amongst a rocky beach of such tiny fragments that stretched as far as the coast curved away in both directions.

This was Nulstrom, the dawn after the Red Corsairs had begun their attack, the sea walls and the habs and factorums that supported them reduced to dust and scorched pebbles by the Red Corsairs’ bombardment.

A shadow fell over Rotaka as the galleon he had been aboard during the battle, the Merciless Strike, rolled slowly over the beach on its great wheeled tracks, crushing the debris even finer. Rotaka’s squad were still belowdecks, no doubt complaining about being away from the action, even though the destruction of the previous night left little ‘action’ to be had.

Rotaka had been summoned to shore after the Fist had made land, along with Huron’s other officers.

They gathered by the Unyielding Fist, incongruous armoured figures on what was now a quiet stretch of shoreline. Huron Blackheart himself was absent, until a screech of metal against metal came from the galleon, and a hatch began to open in its hull. Slabs of encrusted murk and mutated crustaceans fell from the hull as the long-closed hatch opened, and with a further grinding of gears a gangplank extended to the shore.

Huron Blackheart marched down the ramp, his boots pounding the metal which reverberated with each step. His gaze swept across his gathered officers, and many instinctively bowed their heads to avoid his baleful gaze.

‘My Red Corsairs,’ said Huron, his voice a guttural rumble. ‘From here, we could conquer this world. We could enslave its peoples, strip it of its riches, but this world is not enough. If we are to take the system, we must push on to the next world, and the next beyond that, before we can pause to plunder what we have conquered.’

There was a supportive murmur through the gathered officers, though Huron required no affirmation.

‘Inland from here lies the walled city of Rubicon, and within that wall lies the Archway to the world of Kerresh,’ said Huron, lifting the Tyrant’s Claw as if seizing the planet in its pincers. ‘Once we take Kerresh, then the inner worlds are at our mercy.’

There was a cheer from the officers, and a voice shouted, ‘We will reduce Rubicon to dust, as we did Nulstrom!’

‘No,’ snarled Huron. ‘We will not strike in any way that might damage the Archway. We must take the city with minimal bombardment, lest we destroy all we aim to capture.’

The lone voice silenced, Huron explained what they would do once they reached Rubicon.

As Huron dismissed his officers, he made one exception.

‘Anto,’ he said. ‘Speak with me.’

‘My Lord Huron,’ said Anto, bowing deeply as he approached the Tyrant. Looking at the rocks beneath his feet as he approached, Anto could feel two gazes upon him: Huron, and it.

Even looking up, Anto wouldn’t have been able to see it – the Hamadrya, Huron’s constant daemonic companion. Although Anto couldn’t see it, his sensitivity to sorcery allowed him to feel its presence. As he stood straight, Anto could see the Hamadrya’s trail like a miasma around Huron Blackheart, swirling over and around him.

To be in such a relationship with such power. Anto felt envy, but he was not sure whether he envied Huron or the Hamadrya itself.

‘Sorcerer,’ said Huron.

‘My lord,’ said Anto, uncertain of why Huron had summoned him. An audience with the Tyrant could be fatal, and it was impossible to predict what might incur Huron’s disfavour.

‘There is an inquisitor in these Hollow Worlds,’ said Huron. ‘You will locate and kill him.’

‘Yes, my lord,’ said Anto. He knew of the inquisitor already, but was uncertain why a single individual should be of such concern in a campaign spanning worlds, and why Anto should be charged with the assassination when soon the Hollow Worlds would be overrun with Huron’s armies. Huron Blackheart was a madman, subject to fatal whims, but his rages were usually more ambitious in scope than the elimination of one person.

‘Do not take this task lightly,’ snapped Huron, looming over Anto. Clearly some of the sorcerer’s doubts had been betrayed in his voice. ‘Inquisitors are disruptive creatures, filled with guile and skilled in deception. Left free this one will attempt to sabotage my plans in ways the mindless armies of the Corpse-Emperor would never conceive. Use the assets you have in enemy territory – ensure that the inquisitor is dead before he has the chance to disrupt our advance.’

‘Assets? The insektiles, my lord?’ asked Anto. ‘I have no power to direct them remotely, and they cannot pass beyond the Archway–’

Huron moved so fast that Anto had no time to react before the Tyrant’s Claw was nearly in his face. ‘Do not play me for a fool, sorcerer,’ said Huron. ‘Your kind may be used to holding your secrets close, but do not forget who was party to them, and do not forget that without me your Legion would be long dead.’

Huron backed away, looking out to the dark waters of the sea. The sorcerer was in shock, not that Huron knew his secrets – Anto was a fool to think anything less would occur, and he had only kept such secrets for fear that if his experiments failed, it would be safer for them to fail without Huron relying on them – but that Huron Blackheart had referred, even obliquely, to the salvation of the Tiger Claws, long ago when he was still Lufgt Huron. Blackheart never referred to the time before the Astral Claws, to the extent that some even doubted he remembered his former life.

‘A debt that can never truly be repaid, my lord,’ said Anto, head bowed.

‘No, it cannot,’ said Huron, never one for humility. ‘But you will try, Anto, with every power and asset at your disposal.’

He turned back to Anto, his cybernetic eye glowing while the milky, tainted orb of his organic eye stared wildly into space.

‘Find that inquisitor,’ said Huron. ‘Find him, and kill him.’

The Archway dominated the city of Rubicon, a stone curve that cut across the skyline, fringed with crackling, iridescent energy. The space underneath the arch was a blurred void, the transition point between the worlds. At the peak of the Archway’s curve was an ornately inscribed keystone, from which a tower of bright, pure light connected it to the artificial sun. The light was so bright that it was hard to even glance at, and remained a distinct column even at the brightest part of the day. Kretschman held his hand to his brow so he could look at the arch without staring into that light.

For now, he had little to do. He, along with the other Cadians under Ruthger’s command, had shipped out to guard the Archway at the centre of Rubicon and prevent the enemy from travelling through it. A couple of days’ travel crammed into ridge runners had brought them to Rubicon, a city surrounded by a towering wall. While many of the Cadians were posted on that wall, Kretschman was further into the city, posted overlooking a square a short distance from the Archway itself. If the enemy breached the wall, the streets of Rubicon would naturally funnel them towards a number of squares like this, and Ruthger had positioned his forces accordingly.

Kretschman had a rocket launcher and a view of the square, and orders to only open fire under specific circumstances. There were other Cadians posted around the square who would get first blood. Kretschman was fine with that.

So far, all was quiet but everyone knew the enemy were coming since the coastal city of Nulstrom had fallen. Kretschman looked out towards the city wall and the dead forest of towering, blackened trees that surrounded the city, ominous treetops looming in the horizon. On arrival, Colonel Ruthger had ruthlessly begun to lock down and fortify the city, sealing all four great gates in the wall, barricading and fusing them shut.

‘They say that if you look too hard at the light, your soul will be torn out and fed up to the sun, where you’ll serve the Emperor spreading light throughout the world for all eternity,’ said Kulbard.

‘Isn’t that an honour?’ asked Kretschman. ‘Do these locals think that’s supposed to be a heaven or a hell?’

‘I have no idea,’ said Kulbard, shaking his head.

‘When did you get here?’ Kretschman asked.

Kulbard shrugged. ‘Same time as you, I expect. Shipped out on the big train. Typical we shouldn’t find each other.’

Kretschman shrugged back. ‘It was a big train.’

‘A really big train,’ Kulbard agreed.

They were silent for a moment, an easy quiet which comes when the conversation needs to shift gears.

‘So, how is your inquisitor?’ asked Kulbard.

‘You know about him?’ said Kretschman.

‘I make it my business to know what you know,’ said Kulbard with a sideways grin. ‘Especially if it involves changes to the chain of command.’

‘Well, he’s gone now,’ said Kretschman.

‘You shouldn’t have let him out of your sight,’ said Kulbard ruefully.

‘Exactly what I thought,’ said Kretschman. ‘But a man like that cannot be argued with.’

‘A shame,’ said Kulbard. ‘It would have been useful to have him here, for the battle ahead. Do you know where he went?’

‘Out of the system, according to him,’ said Kretschman.

‘And that’s all you know?’ pressed Kulbard, staring straight at him but before he could answer, Kulbard backed off. ‘Of course it is,’ he said, looking away. ‘Apologies.’

They were silent again, both thinking of the battle to come.

‘I must prepare,’ said Kulbard eventually, stepping away. ‘Look after yourself in this one, Kretschman – we cannot afford to lose men like you.’

Kretschman was going to tell Kulbard to do the same, but when he turned around his friend had already disappeared from the rooftop, presumably back down to street level.

The door was a rusted square of metal in the side of the mountain. Theoretically it opened sideways, sliding across. As Pranix pulled on the handle, the blizzard lashing his face, fingers numb even beneath thick gloves, he was driven by the fact that there was no turning back. It had taken him hours to walk the mountain paths through the storm to reach the door, and there was no way he could find his way back to the vehicle Ruthger had given him. Pranix had set out on foot when the trail narrowed, leaving the Cadian driver dead at the wheel, a las-shot burned in the back of his head. The Inquisition kept its secrets carefully.

Pranix would not freeze to death out here. He refused to. He reached out with his mind and gave the door a telekinetic slam, dislodging rust and ice from around the frame. Slowly, with a metallic grinding, the door opened, releasing a rush of tepid, stale air.

No one had visited the station for a decade or two, to the best of Pranix’s knowledge.

He pulled the door shut behind him, and switched on the luminator clipped to the lapel of the Cadian greatcoat he was wearing. He was in an open, crude cave that trailed off into darkness. The station wasn’t entirely unmanned, but its workforce didn’t need light. He could hear heavy footsteps, rattling breaths, and the endless clicking of mechanical switches. And to accompany the noises, a smell of ancient decay, of heated dust and long-dead flesh and bubbling engine oil.

Two servitors, ancient and corroded, stumbled into the light of Pranix’s luminator. Centuries of neglect had left them in poor condition. There was a burble of mechanical chittering as they addressed him.

‘I am Lord Inquisitor Pranix,’ said Pranix, activating his hololithic crest. ‘Here is my identification.’

The servitors let out another chatter, acknowledging his status.

‘Return to your duties,’ said Pranix. ‘I expect all information logs on regional conflicts to be fully up to date, and will consult them later. And prepare the exit launcher.’

The Inquisition had found this place many centuries ago, and had built their station upon a borehole that ran beneath the surface of the world, from beneath the mountain, deep under the crust, to emerge on the outer surface of the planet. A back door to the Hollow Worlds, known only to the Inquisition. It was Pranix’s only route out, but even to him the prospect of such a dangerous flight was intimidating.

The two servitors chuntered off into the distance, wheezing and clanking as they went. Stretching his cold muscles, Pranix had a rare moment of hesitation before following them into the dark.

Ten

The forests around Rubicon were long dead. The trees were blackened skeletons, fossilised branches reaching up to the artificial sun above. They were twice as tall as the galleons of the Red Corsairs, but brittle, and the prow of the Unyielding Fist smashed through them as the galleon rolled slowly through the forest.

Rotaka and his squad were on the deck of the Fist, clearing dead wood that fell in huge splinters onto the deck. While such menial duties would usually be left to slaves, the Red Corsairs’ greater strength was needed to keep the deck clear and allow the galleon to keep moving. Lord Huron did not wish their progress to slow. The blood of mortals torn apart by shards of wood when the galleons first rolled into the forest still smeared the deck.

The crash as each tree fell was deafening, and echoed out across the leafless forest.

‘I think they might hear us coming,’ said Malinko, throwing a huge hunk of wood overboard.

‘Let them hear us,’ said Hulpin, using his chainfist to hack apart a log. ‘They still won’t see us.’

In the ruins of Nulstrom, Huron had explained his plan for Rubicon to his officers. The city was accessible by four roads cutting through the forest, each of which led to one of four gates in the city wall. The defenders of Rubicon would doubtless have locked, reinforced and blockaded those gates, set up mines and traps on the approach roads, and concentrated the majority of their forces on the wall close to those gates. Each gate would effectively be a barrier stronger than the wall itself.

Huron Blackheart therefore planned to go straight through the wall, at a point simultaneously distant from the nearest gates and which allowed the quickest approach to the Archway that dominated the city.

‘Brace!’ came a shout across the deck, and the Fist began to turn in the direction of the city, arcing to port. Rotaka looked in that direction and could see that the other galleons were turning to face the city wall, which was obscured by the dense trees.

‘All hands off deck,’ came an order across the vox. ‘Ready cannon.’

‘Disappointing,’ snarled Malinko as Rotaka and his squad, along with all the other Corsairs on deck, ran for the hatches. ‘I was looking forward to this.’

The huge-barrelled guns that dominated the decks of the galleons had been lowered as far as they would go, dangerously low, so that when they fired the shells would barely clear their prows. The blast as the shell streaked above would kill anything on deck.

Wuhrsk was last below deck, and pulled the hatch down behind him. There was a pause as the Corsairs, crammed into an access corridor, waited.

When the order came over the vox-speaker in the wall, it was the Tyrant himself who spoke the single word: ‘Fire!’

There was a colossal blast overhead and Hulpin, still holding on to the handle of the hatch, was nearly pulled off his feet as the slipstream from the shell almost tore the hatch out of the deck.

There was a distant explosion and Garreon’s voice came over the vox: ‘All galleons, forward. All Corsairs on deck and prepare to take the wall.’

The Unyielding Fist started to roll forwards, and as it picked up speed Hulpin threw open the hatch and the Red Corsairs clambered out back onto the deck.

Checking his weapon as he clattered up the stairs, Rotaka looked out to see a blackened, smoking streak bisecting the deck. A swathe had been cut through the forest and a great rockcrete wall loomed ahead, taller than the galleons but shorter than the dead trees, pockmarked and smoking but still intact. Beyond that wall, in the distance, could be seen the prize the Corsairs sought today, the shimmering Archway that provided access to a whole other world.

On deck the Corsairs gathered into their squads, preparing for their attack. Rotaka looked between the members of his squad.

‘Let’s take the wall,’ he said. ‘For Lord Huron.’

‘For the gods!’ added Hulpin.

‘For fun!’ said Malinko.

Wuhrsk made a grunt of disapproval, shaking his helmeted head, while Verbin let out a short bark of a laugh.

Either side of the Fist other galleons were moving in closer. Just as it seemed the galleons were going to crash into each other and the wall ahead, they came to a sudden halt. The Red Corsairs on deck jerked forwards, only their magnetic boots keeping them in place. There came a great rumbling of machinery from belowdecks, and a hook was fired from just beneath the prow, a huge rusty claw dragging a chain behind it that shot forwards, smashing into the wall of rockcrete and digging deep. From the other ships of the line came similar hooks, digging into the wall in a cluster. The galleons began to pull back, but the walls held as the chains tightened.

‘Attack!’ came the order, Garreon’s voice once again echoing across the vox. ‘Launch all grapples.’

Three Red Corsairs at the prow of the Fist used a deck-mounted launcher to fire grappling hooks up to the battlements on the wall. The launchers, firmly secured to the deck, reeled the cables back until they went taut, and the first Red Corsairs began to swing over the prow of the Fist, climbing hand over hand as they hung to the cables. Similar assaults were being made from the other galleons.

Rotaka had just begun to climb when the defenders of Rubicon, clearly taken by surprise by this sudden attack on a remote stretch of the wall, began to counter-attack. Las-fire rained down from above, largely ineffective against the power armour of the Red Corsairs. Rotaka kept climbing as fire was returned from the deck of the galleons, temporarily driving back any resistance that might dislodge the grappling hooks from the top of the wall.

‘See, fun!’ shouted Malinko over the vox. Rotaka ignored Malinko as well as the stream of abuse Wuhrsk replied with.

Rotaka was halfway between the deck of the Fist and the wall when a rocket streaked overhead in the opposite direction. He didn’t see where the missile landed on deck but he could take a wild guess when the cable in his hands went slack, torn free from the deck behind him, and Rotaka and the others started swinging towards the rockcrete wall.

Holding tight, braced for impact, Rotaka glanced back as he swung towards the wall, only to see that Hulpin had lost his grip and was falling to the scorched forest floor below.

Rotaka let go of the cable too and flung himself towards Hulpin, twisting his armoured body around in the air. Hurtling down, aware that to ignite his jump pack at the wrong time would send him down even faster or into the hull of the Fist, Rotaka moved agonisingly slowly as he fell, keeping his eye on the flailing Hulpin.

At the last moment Rotaka managed to arc his back right and activated his jump pack. He shot forwards, crashing into Hulpin, awkwardly grabbing on to the other Red Corsair’s arm. The jump pack shuddered and spluttered as the two boosted upwards, burning fuel even quicker than usual. Rotaka only had a few seconds of thrust left. He began to feel a loss of momentum as they lifted past the giant chain that extended between the Fist and the wall, and arced towards it as the jump pack spluttered and died.

Rotaka and Hulpin fell once more, only for Hulpin to be caught in one link of the chain. It was his turn to hold on to Rotaka, who dangled uncomfortably over the edge before Hulpin pulled him up.

‘Try to hold on this time,’ said Rotaka, uneasily standing up on the oiled link, a loop of ancient metal the size of a Space Marine.

‘Yes, brother,’ said Hulpin and they resumed their advance towards the wall.

When the cable had broken, Malinko had clung on as he swung towards the wall, his boots smashing holes in the rockcrete as his full body weight crashed into it. He began to climb up, hand over hand, boots kicking small indentations in the surface of the wall, sending little torrents of rock dust into the air with every impact. He looked down and was delighted to see the sheer drop below. Looking up, the air was criss-crossed with grappling lines, las-fire and the smoke trails of rockets as the mortals on the top of the wall exchanged fire with the slaves on board the galleons, who had returned to the decks to man the gun batteries and provide covering fire for the Corsairs.

Such wonderful carnage. Malinko started climbing faster so he could get closer to the destruction.

He was not alone climbing the wall. As well as those Red Corsairs still clinging to the same cable, others had used jump packs to reach the wall and were punching their own hand and footholds. Rotaka and Hulpin had somehow ended up crossing the gap by walking on top of the chain connecting the Unyielding Fist to the wall of Rubicon.

Above, there were shouts, and a patch of shade fell over Malinko as some great object was tipped up. He swung to the side, dodging as burning liquid rained down on his previous position. He doubted the mortals had anything that could burn through power armour, but he didn’t want to take the risk.

Malinko nearly knocked Wuhrsk, who was climbing to his right, off the wall as he swung sideways, but Wuhrsk caught Malinko by the arm and they dangled together, briefly, as the boiling liquid flowed down the wall.

‘Enjoying yourself?’ hissed Wuhrsk, expression unreadable behind his helmet.

‘Of course!’ said Malinko, regaining his own grip on the wall.

Letting go of Malinko, Wuhrsk resumed climbing without saying a word.

By the time Rotaka and Hulpin pulled themselves up onto the battlements, a small stretch had been taken, but the occupants of the city were rallying. Around the curve of the wall, mortals were moving in from both directions, subjecting the invaders to a barrage of bolts and las-fire.

More Red Corsairs were coming up behind them. As Hulpin helped Wuhrsk up, Rotaka saw that Verbin had got ahead of them and was providing supporting fire to Becaro’s squad, who were fighting off the mortals to the right. To Rotaka’s left, a similar group was blockading the battlements in the other direction. The Corsairs were shoulder to shoulder, with no room for Rotaka to add his bolter to the battle.

He looked into the city, over the low wall that ran around the inside lip of the battlements. Below was a warren of deserted streets between closely crammed buildings of various heights, huddled together in the space between the city wall and the Archway.

Rotaka only had a second or two to take all this in before a rocket from the roof of a building a few blocks away streaked towards him. He ducked behind the low wall, against which the rocket exploded, fragments of hot rockcrete filling the air.

Garreon’s voice came over the vox: ‘Is the target area secure?’

A chorus of ‘ayes’ echoed over the vox.

‘Then brace,’ said Garreon.

On the bridge of the Fist, Garreon turned to the Tyrant, who stood silently flexing his claw.

‘Area secure, my lord,’ said the Corpsemaster.

Huron simply nodded, his glowing augmetic eye gazing balefully at Garreon as if to say that any failure would be his fault.

Garreon pushed a sigil allowing him to vox the bridges of all the galleons.

‘On three, full power reverse and all batteries fire on target areas. One, two, three!’

As one, the galleons pulled back, the chains fixed to the wall tautening. Simultaneously, the galleons’ smaller guns began to pepper the sections of the wall the Corsairs had taken with explosive fire, chipping away at the rockcrete surrounding that stretch of the wall.

Ahead of the galleons, the air was filled with smoke, and from his position on the bridge of the Fist, Garreon couldn’t see whether the bombardment was working. All he could feel was the judder of the deck beneath his boots as the galleon pulled against the wall.

That tension could not last. Sooner or later, something would give.

Beneath Rotaka’s booted feet, the wall began to shift.

Rotaka risked looking over the inner lip of the battlements once more, down into the city below. It was a long way down, and thin cracks were beginning to emerge on the interior surface of the wall.

As the guns of the galleons battered the city wall on either side of the position held by the Corsairs, Becaro and the others withdrew to Rotaka’s position. The battlements to either side of them had been pulverised by the onslaught, driving back any mortal resistance.

The stretch of battlements they stood on shifted outwards, towards the galleons.

This was lunacy, thought Rotaka, and he knew what to do.

‘Malinko,’ he shouted over the roar of explosions and creaking rockcrete. ‘Will you lead us down to the city?’

‘It will be an honour,’ said Malinko. He turned to address his fellow Corsairs. ‘On my–’

He was drowned out by the sound of rockcrete cracking, as loud as a thunderclap, and the entire section of wall on which they stood began to topple backwards, the galleon’s wheels spinning free as it pulled away and dragged that chunk of wall down.

‘Now!’ shouted Malinko as he jumped over the edge of the wall. The interior of the wall was no longer a sheer drop, but an increasingly sloped surface, and Malinko landed on that slope and began to descend on his heels.

Rotaka and the others jumped after him.

From the top of the wall to the paved street below, their descent must have taken a matter of seconds, but to Rotaka’s enhanced senses time seemed to slow, each moment stretching as he took in every potential threat, registered it and chose how to respond. Rotaka fell backwards as he hit the wall, sliding down on his back with his heels digging in to give himself some moderate level of control. He leant to the right to avoid an expanding crack from where their section of the wall had broken away – that section was falling to pieces around them, and they would be lucky to reach the bottom without being buried in falling rubble.

In all, there were over two dozen Red Corsairs sliding down the wall, and as they descended closer to the streets, mortals began to emerge from cover and fire upon them. Rotaka almost respected those mortals who had the nerve to open fire upon a descending horde of Red Corsairs, a terrifying spectacle no doubt unlike anything these worlds had seen before.

That respect wasn’t enough to discourage Rotaka from returning fire. At this speed of descent, the shots from his bolter flew wild, but it hardly mattered: each explosion of a bolter shell disrupted the mortals’ attempts to target the Corsairs, raised their panic and made the chances of anyone down there taking another clear shot virtually nil.

As the Corsairs reached the end of their descent, Malinko led the way, launching himself away from the wall before reaching the bottom. Screaming oaths, he landed amongst a crowd of mortals and raised his flamer, letting loose a torrent of burning promethium.

Hitting the ground and rolling into a firing position, Rotaka tried to get his bearings, but a great cloud of dust from the collapsing wall behind him consumed the Corsairs and everything in its path.

Rotaka switched his helmet settings to track heat and motion. Ahead of him was a white-hot blur where Malinko had set his surroundings ablaze, but beyond that Rotaka could see red figures, most partially obscured by the cool blue of the barricades and walls they hid behind. His fellow Corsairs were the same blue as their surroundings, bulky hills of cold ceramite visible by outline as they moved.

He fired quickly, and the other Red Corsairs did the same, bolters turning red, then white on the thermal sensors, the motion of the bolts streaking across Rotaka’s vision as they sped to their targets. Rotaka was systematic, sweeping his bolter up and across, finding red figures, squeezing the trigger briefly and moving on. There was a white burst of heat as each bolt found its mark – one, two, three targets down at windows and balconies. The smoke and dust in the air wasn’t giving the mortals any chance to fire back.

Ahead of Rotaka, the mortals had fled from Malinko, and he had let his flamer rest. Sweeping his bolter back and forth for targets, Rotaka caught up with him. The enemy seemed to have retreated, with no red figures visible through the cloud. Then, before he could even speak to Malinko, he saw tiny streaks of motion overhead, small projectiles cast through the air towards them.

‘Grenades,’ shouted Rotaka, rushing for cover. There was little room for manoeuvring in the narrow street and he slammed himself into a wall as an explosion went off far too close, whiting out his thermal vision. He swore and switched back to normal vision. The dust cloud had largely settled, though the grenades were throwing up more debris now. Hugging the wall, Rotaka looked ahead to see mortals surging forwards, opening fire as they ran from cover to cover. The streets were a warren, branching off in three ways, and the mortals were ducking into doorways and arches to create a kill box ahead of the Red Corsairs.

Then Rotaka heard a growing roar from behind him, and glanced back to see an army of slaves climbing through the gap in the wall. They were not an impressive sight, pallid and starving from long years in the depths of Huron’s spaceships and land galleons, but they were many, and their desperation had bred in them a savagery that made up for their weak bodies and crude weaponry.

And there, cutting through the centre of the horde, was Huron Blackheart himself, towering over the mob of slaves, striding at the speed they ran.

‘Do not hesitate – do not indulge in slaughter or stop to secure territory,’ he shouted, his voice carrying over the heads of them all. ‘Press on, press on and seize me the Archway before nightfall.’

Blood pumping from this address, Rotaka swung around and opened fire on the mortals, determined to stay ahead of the horde and be one of the first to reach the Archway, to take it for the Tyrant.

It had begun with the sound of distant thunder, a rumbling coming from the forest all around the city. Then came the roar of explosions, and a plume of smoke at the city’s edge. From his perspective on the rooftop, Kretschman could not see what had just happened, but he could guess, not just from the smoke and dust but from the shouts of Jandarme and Cadians rushing through nearby streets. Somehow, the wall had been breached and the enemy were in the city.

While below his comrades at street level rushed to seal the breach like blood cells flowing towards a cut, Kretschman knew his duty was to maintain his position.

Resting the rocket launcher on the low parapet that fringed the rooftop, Kretschman tuned out the distant, approaching noise of gunfire and concentrated on his job: watching for the enemy’s approach.

Colonel Ruthger had established his command centre in Rubicon as close to the Archway as he could. He had chosen a narrow gallery overlooking the Archway, with thick red curtains and incense in the air and a single, heavy double door at one end of the room. Tech-priests made incantations and manipulated sigils on cogitators. Ruthger had presumed from all this ritual that the Adeptus Mechanicus had full control of the workings of the Archway.

‘What do you mean it won’t close?’ demanded Ruthger. He had been prepared for death, but not this.

‘The Archways are very ancient unknown technologies that we do not fully understand. It took many centuries for our predecessors to establish rituals to manipulate those technologies,’ said the tech-priest with an infuriating lack of urgency. ‘Our knowledge has always been incomplete and the records of our ancestors are, sadly, lost.’

‘So you know nothing about nothing,’ said Ruthger. ‘That doesn’t explain the problem.’

‘The controls have become infected with scrapcode,’ said the tech-priest. ‘It must have lain dormant, as we did not realise that those systems were even connected to the communications until we tried to close the Archway. Now the system is frozen, and the Archway remains open, with no means to shut it.’

Ruthger looked out of the window of the gallery, which overlooked the far corner of the Archway. The gallery was several storeys up, but the stone curve of the Archway was massive, and this close Ruthger could see baffling symbols carved into the stone. Even through multiple shielded glass of the kind used in deep space – the tech-priest had tediously explained this a few hours before – the Archway’s energies were fiercely bright. Below, a riot was in progress as civilians tried to push through the Archway before it closed. There was the sound of gunfire as Guardsmen drove back the civilians who had not passed the final checkpoints before the Archway, so it could be bolted and barricaded.

Those who weren’t shot would die in Rubicon, thought Ruthger. But if the Cadians allowed civilians through the Archway and didn’t close it, it would be a very brief reprieve. Ruthger had to sacrifice the people of Laghast to give those on Kerresh a fighting chance.

‘You do not understand the mysteries of this technology,’ said Ruthger, moderating his tone. He knew that for the Adeptus Mechanicus, especially the lowlier tech-priests, the mysteries of machines were part of their religious significance, and it did not help to enflame their fervour on these matters. ‘But you must maintain these technologies, yes? Perform the rituals to keep them in working order.’

‘Of course,’ said the tech-priest, nodding his hooded head.

‘And which are the most important, would you say?’ asked Ruthger.

The tech-priest thought for an infuriatingly long time before answering. ‘The scrolls emphasise the significance of the banks of cogitation, and the rotors of alignment, but also the importance of maintaining the generators and the adjacent banks of power converters.’

‘Wonderful,’ said Ruthger. ‘We’ll need to take those out of action.’

‘Which ones?’ asked the tech-priest. Even through the harsh modulation of his artificial voice box, he sounded alarmed.

‘All of them,’ said Ruthger.

Eleven

Rotaka told himself that he did not debase himself like some of his fellow Red Corsairs, that he did not indulge in carnage for carnage’s sake, that he fought to carry out his orders and did not bathe in blood as an indulgence.

Regardless, he felt something close to joy as his squad fought their way through the streets of Rubicon.

Malinko took the lead, dashing from cover to cover, getting as close as he could to enemy lines before unleashing a burst of fire from his flamer. As Malinko darted around he drew fire from snipers high above, and Wuhrsk, clinging to the walls and staying in shadow, tracked back each shot to its source and returned fire. Rotaka and the others provided covering fire at ground level, taking out any mortals who emerged from behind their barricades to try to stop Malinko’s stuttering charge.

They were making good time, not the speed they would if they were free to run through empty streets, but they were systematically fighting through the city’s defences. In rare moments where Rotaka’s squad were not in combat he could hear nearby gunfire and shouts, as other Red Corsairs squads and Huron’s slave army fought their way through parallel streets, all weaving towards the Archway.

At the end of one street a light barricade blocked the way, undefended. The snipers seemed to be holding back too. Beyond the barricade Rotaka could see some kind of square, and beyond that the Archway, gleaming with temptation.

‘Malinko, halt,’ Rotaka snapped into the vox. ‘Hulpin, take down that barricade.’

‘Yes, my lord,’ said Hulpin, dashing past Malinko, bolter locked to his leg and chainfists thrumming. The barricade was a high metal fence of solid sheets, and Hulpin’s chainfists tore straight through it, cutting a criss-cross through the metal. Weakened, the middle of the barricade collapsed in on itself as Hulpin gave it a kick before withdrawing to cover.

Rotaka was expecting a hail of gunfire as the barrier went down, but as his squad took cover there was no response. Through the gap in the barricade he could see a small open plaza with worn-down, faceless statues in the centre, memorials to some long-forgotten heroes of the Imperium. At the other side of the square was a street leading to the Archway. The route seemed clear.

‘It must be a trap,’ hissed Wuhrsk over the vox.

‘Of course it’s a trap,’ said Hulpin. ‘The gods may favour us, but they offer nothing of worth to those who do not fight for it.’

‘Thanks for that, very helpful,’ said Rotaka. ‘Verbin, can you get a grenade right in the middle of those statues?’

‘Ugly things,’ Verbin growled. ‘A pleasure.’

Stopping short of entering the square Verbin ran forwards and cast a grenade overarm, the small sphere sailing through the air and landing perfectly between the worn statues.

There was a moment of silence, and then the grenade detonated, blowing the statues into chunks that scattered across the square. Where several chunks landed there were further detonations, the debris setting off hidden mines. As explosions spread over the square there were brief bursts of gunfire from high windows and rooftops, before someone realised they were firing on smoke and the firing stopped.

‘What now?’ said Malinko. ‘I say we get in there and draw them out.’

‘Let’s at least reach the objective before making a last stand,’ said Rotaka. ‘You and Wuhrsk stay here – take a few shots at likely sniping positions every minute or so. Hulpin, Verbin, you’re with me.’

‘Where are we going?’ asked Hulpin.

Rotaka pointed to the rooftop of the nearest building.

‘We go up.’

Coming up against a Red Corsair in person was a different thing to seeing one in a blurry visual feed. The figure that ran into the square below, threw something, then ducked back out of sight again, was a muscular, armoured mass of shifting, bloodied plate. It also moved faster than would be thought possible for a creature that size, and Kretschman nearly fired his rocket launcher in shock, expressly against orders, twice: once at the entrance of the figure into the square, terrifying even from a distance, and again when the grenade exploded in the centre of the square.

The Red Corsairs knew it was a trap. Kretschman waited to see if this would change the Cadian plans.

‘Hold position,’ came an order over the vox.

It took a matter of minutes for Rotaka, Verbin and Hulpin to reach roof level, smashing through the doors of a nearby building and charging up narrow stairs, their pauldrons dragging across plasterwork as they squeezed through spaces built for mortals. The interior of the building was deserted, any mortals having fled. They reached the rooftop intact, running out into the open air to find a couple of squads of Cadians aiming sniper rifles and a grenade launcher over a balustrade into the square below.

‘By the Empero–’ the officer began, turning and drawing his chainsword, but before he could either finish his sentence or begin to attack, Hulpin had jammed a chainfist through the man’s chestplate.

‘Leave the launcher intact!’ Rotaka shouted, firing a couple of bolts into the Guardsmen. ‘Hulpin, take these. Verbin, take the launcher.’

With an oath to the gods, Hulpin crashed into the first group of Cadians, swinging his chainfists back and forth, cutting through vulnerable mortal flesh. One Guardsman was flipped over the roof edge. There was an explosion from below as he landed on a mine.

That left the squad manning the grenade launcher to Verbin. As he ran at them, two Cadians managed to twist the launcher around from its tripod and aim it right at the Red Corsair. They fired, but at such close quarters the grenade bounced off Verbin’s armour and ricocheted high into the air. Verbin grabbed the barrel of the launcher with both hands and swung it back and forth, shaking off the Cadians, who scrambled for their lasrifles. Rotaka shot one of the Cadians in the shoulder, while Hulpin dealt with the others.

‘What should I do with thi–’ said Verbin, ducking down mid-sentence as the balustrade exploded under the white-hot impact of high-intensity las-fire.

Rotaka and Hulpin did the same, las-shots and chunks of masonry flying overhead. Rotaka glanced through a crack in the balustrade to see a quad-barrelled lascannon mounted on a rooftop at the other end of the square. He turned to Verbin. ‘Now you know what to do.’

Verbin nodded and started prepping the grenade launcher.

Rotaka dragged one of the dying men up by the collar with one hand, and grabbed on to his belt with the other.

‘Let’s clear a path through that minefield,’ he said, and with one swing threw the dying man over the parapet. Hulpin grabbed a dead man and did the same.

One of the bodies set off a mine when it landed, the other didn’t.

Verbin fired the grenade launcher, and a couple of seconds later there was an explosion and the lascannon ceased firing.

‘Wuhrsk, Malinko, follow the trail of intact bodies,’ Rotaka said into the vox, and he and Hulpin threw another couple of bodies over the edge, keeping their heads down, casting each one a little further than the last.

Kretschman had held his position throughout the entire conflict at roof level. His orders were clear – maintain a line of fire on the entrance to the square; only fire once the mines, traps and lascannons had done their work. His assigned rooftop was at the side of the square, and from his position behind the balustrade he was invisible to both the grenade launcher crew and those Cadians manning the lascannon.

His eyes still focusing on the entrance to the square, he had to try to ignore the carnage at rooftop level, only glancing up quickly to ensure he wasn’t discovered. As much as anger and honour demanded he target the Corsairs on the rooftops as they killed his fellow Cadians, throwing the bodies off the roof and destroying the lascannons opposite with a grenade launcher, Kretschman had his orders. He watched the entrance to the square, blinking beads of sweat from his eyes.

Then they came, when the Cadian weapons were silenced, two Corsairs dashing out into the square, following a trail of mortal corpses to cross the minefield safely.

Not safely enough, thought Kretschman, and it was with a feeling of righteous fury that he fired a rocket right at them.

Wuhrsk scanned the rooftops and the windows for possible snipers as he and Malinko dashed across the square, following the trail Rotaka and the others had made for them. Malinko was charging forwards without restraint, making a target of himself, which gave Wuhrsk a certain comfort in their exposed position, the comfort that at least he was unlikely to be targeted first, and that if there were any undetonated mines in their path Malinko was likely to stand on them.

When he heard the rocket cutting through the air towards them, Wuhrsk was already turning, searching for the point of origin. As the rocket hit the ground and exploded between Malinko and Wuhrsk, both Red Corsairs were thrown off their feet, but Wuhrsk was raising his bolter, tracing the trail of smoke back to a high point on a rooftop.

Before the explosion consumed him, Wuhrsk fired.

The bolter shell would have hit Kretschman square in the head, if he hadn’t been partially hidden behind one of the crenellations of the parapet. Instead, it hit rockcrete and exploded next to him, fragments flying and smashing into the side of his helmet.

Veteran Sergeant Kretschman was knocked off his feet, and his helmeted head slammed backwards into the floor, hard. His vision blurred, and he lost consciousness, the sound of gunfire down below the last thing he remembered.

Rotaka dropped to ground level, ran over to the prone and scorched Malinko, and kicked his armour. Malinko groaned.

‘If you’re alive, you can get up,’ said Rotaka. ‘We need to get to the Archway – I can hear them approaching.’

‘The enemy?’ asked Wuhrsk, Hulpin helping him back to his feet.

‘Worse,’ said Rotaka. ‘Our comrades. I’m not letting Becaro get all the glory.’

Kretschman was woken by shouting, someone leaning over him and shouting so loud they seemed to punch through into his unconscious mind, dragging him back to awareness of the external world.

‘Get up, Kretschman,’ Kulbard was shouting. ‘The Archway is lost.’

‘Lost?’ Kretschman said, forcing himself into a sitting position. There was a terrible pain in the back of his skull that crept down his spine and left him wanting to vomit.

‘Yes, lost,’ said Kulbard, not shaking or otherwise jostling Kretschman – for which Kretschman was grateful – but getting right in his face. ‘You need to evacuate, get through that damn Archway.’

Kretschman struggled to remember what he’d been doing before he lost consciousness. Yes, there had been an attack; he had fired a rocket launcher… He could see around him that he was still on the rooftop.

‘Need to defend square,’ said Kretschman blearily.

‘There’s nothing to defend – the square is overrun,’ said Kulbard. ‘Come on, sergeant, this isn’t a rout, this is a strategic withdrawal. We can’t afford to lose you this early in the campaign, so get up.’

‘If the city is lost,’ said Kretschman, dragging himself to his feet, ‘how am I supposed to get to the Archway? One step at street level and they’ll tear me apart’

‘Think,’ said Kulbard. ‘Think what you saw earlier.’

Kretschman staggered over to the other edge of the roof. Below, he could see the bundle of pipes, covered in a mesh cage that stretched away from the building and passed over the intervening buildings. The sound of fighting was harsh down there; clearly some final defence of the Archway was still ongoing.

It was a long drop, but if he could land on top of that, and it held his weight, it could take him at least as far as where he could help with the last defence.

‘Never mind strategising, leave that to the officers,’ snapped Kulbard. ‘Now jump.’

So Kretschman jumped. The drop was twice his height, and the impact was jolting. As he landed, he was nearly knocked straight off by an explosion nearby, which tore through an adjacent building and filled the air with smoke.

Kretschman’s fingers sank between the mesh of the cage, and he held on tight as the tremor from the explosion subsided.

‘Kulbard?’ he shouted, but he couldn’t see whether the scout was with him or not.

‘Never mind me,’ he heard Kulbard shouting. ‘Get moving. I’ll follow.’

Kretschman got moving, pulling himself and running along the caged pipes as fast as he felt he could while half-blinded by the smoke, the iridescent glow from the Archway ahead his main guide through the clogged air.

‘We will buy you as much time as we can,’ Ruthger had told his second, Lieutenant Nistal, before the younger man had saluted solemnly, silently and walked through the Archway without looking back.

That had been less than an hour ago, Ruthger was sure of it. Alongside the rump of his regiment he had been fighting ever since, trying to hold the line while most of the men evacuated through the Archway, while also buying time for the equipment that controlled the portal to be rigged with explosives.

Time was nearly up. The approach to the Archway was a long open courtyard, segmented by walls and barriers designed to control flows of people and traffic. The Cadians had locked gates, piled up barricades and otherwise blocked routes to the Archway, and once the Red Corsairs had come within firing range they had thrown everything at the enemy to slow them down – mortars, grenades, rockets. The city was finished; there was no need to hold back.

Ruthger had realised the Corsairs were showing greater restraint, deploying only lasweapons and bolters, presumably to avoid damaging the Archway.

Tough, thought Ruthger. You don’t get this prize intact.

A short distance from Ruthger, a barricade was smashed down by a huge figure in blood-red armour. Cadians ran fearlessly to engage the monster, opening fire with their lasrifles but also getting in close, willing to let their bodies slow this atrocity down, if that was what it took.

‘Detonate now,’ Ruthger shouted into the vox. ‘I don’t care if it’s ready – blow it all now.’

There was a hiss of static from the vox.

Ruthger swore. More Traitor Marines were bursting through the line, opening fire on his men, getting in close to bat them aside with incredible strength, or cut them down with bloodied blades. Every instinct of Ruthger’s being told him to stand with his men, to make his last stand here. But that stand would mean nothing if the Archway was left open.

So instead Ruthger ran, firing off a couple of shots from his bolt pistol as he made for the stairwell that led to the control gallery overlooking the courtyard.

Rotaka and his squad had just broken through the barriers and were fighting the last few steps to the Archway when the bolt-round exploded against his pauldron. Smashing the head of a Cadian soldier with his spare fist, Rotaka looked across to see a mortal in officer’s uniform dashing across open space towards a building at one corner of the Archway. Rotaka raised his bolter and let out a shot, but the man ducked into the building and the bolt exploded harmlessly against a wall.

He cursed, then turned his attention to the fight at hand, opening fire on another Cadian. They were so close to Lord Huron’s prize.

Running up the stairs to the gallery, lungs burning and legs aching, Ruthger had a few seconds to reflect on his life. All Cadians dreamed that their deaths would be in moments of glorious combat. But dreams of honour and glory were not always compatible with the demands of duty and the practicalities of the battlefield.

Ruthger wouldn’t get the death he wanted. But it was the death he needed to have.

‘Blow it all now!’ he shouted as he burst into the gallery.

The men preparing the explosives hesitated for a second, aware that they were being ordered to their deaths. But only a second – they were Cadians after all.

Someone pressed the detonator. Ruthger didn’t see who; he just saw the light that tore through him. Then nothing more.

Kretschman felt the explosion as much as he heard it. He had followed the caged pipes around the edge of several buildings, hearing but not seeing the firefight going on below. Running out of pipe, he had climbed down to a narrow maintenance gantry that took him most of the way to the Archway.

The explosion knocked Kretschman off his feet, and he nearly rolled off the edge of the gantry. He had no real idea what the source of the explosion was – it was near, flame pouring around the next corner of the wall the gantry clung to.

Kretschman pulled himself up and looked ahead. The end of the gantry was a short distance away, and from there only a few metres of empty space lay between the safety rail and the glistening surface of the Archway itself.

There was a sound of thunder, and Kretschman looked up. The sky was clear, the seas of Laghast visible above, but something else was happening. The luminescent fringe around the stone of the Archway was pulling itself away, as the unnatural surface began to contract.

The Archway was closing.

Rotaka too had seen that the Archway was closing. Across the other side of the courtyard he could see Red Corsairs pouring into the space, charging towards the shimmering portal, but it was shrinking faster than they could run. At the centre of that group was Huron Blackheart, towering over the remaining mortals as he pushed through them, and although Rotaka was far away from them, he could hear Huron’s screams over the vox.

Kretschman ran, not sure exactly why he was so keen to make an undignified leap to his own death, rather than at least staying to die with honour, fighting the enemy.

Perhaps it was the concussion. Kretschman felt as if he could hear Kulbard speaking to him, not in words but with an expression of pure will, urging him on, whispering a desire for survival.

Or maybe it was just that he was a Cadian, and he would do any stupid thing for the chance to fight another day.

Kretschman didn’t slow down as he reached the end of the gantry but took a single running step off the safety rail, propelling himself upwards and forwards, off the rail and towards the collapsing portal.

Portal. That was what it was now that it had detached itself from the Archway and started to contract, a hole in the fabric of the world, shrinking with every second. Kretschman fell, his forward momentum carrying him towards that hole, but then his downward descent was stronger than his forward momentum. He was going to go under the closing portal, passing under the Archway to what was now just another part of Rubicon, to land broken at the feet of his fellow Cadians as they fought for the last second and–

–and–

…and he was back on course; whether from a freak wind or some twitch of reality, he was up again. Kretschman hit the last small, frayed circle in the world just as it closed and he was sinking, sinking into infinity, and the portal closed and both he and it were gone.

Elsewhere on Laghast, due north of the city of Rubicon, Lord Inquisitor Pranix braced himself against the wall of the escape pod he had boarded as it hurtled down a tunnel that dug through the very surface of Laghast itself, from a mountain on the planet’s inhabitable interior to a hidden exit hatch on the exterior of the world.

Without astropathic guidance, he had set a manual course for the warzone he had found in the Inquisitorial reports. There was some irony in it being that company that Pranix was required to seek aid from, but Pranix did not let that concern him. Neither did he let any sign of disturbance show on his face as the movement of this crude vehicle, on which his survival and the rescue of the Hollow Worlds depended, rattled every bone and organ in his body.

The pod burst out from the surface, boosters flaring to escape the planet’s low outer gravity and launch into space.

Too small to activate either the guns of the Red Corsairs fleet or the automated defences of the Hollow Worlds, the pod flew past the enemy ships as they floated, docked around Laghast. The main danger to the pod was not that it would be targeted, but that its own pre-set course away from Laghast would cause it to crash into one of the docked ships.

Pranix, impotent to change course once in flight, watched the outward scanners as the pod passed close to a great Murder-class cruiser, a monstrous vessel scabbed with weapons turrets and unholy, organic-looking outgrowths.

But the pod passed by, narrowly missing the void shields of the great ship.

Then it was out, out into space, leaving the Hollow Worlds behind.

In those last seconds before the portal to Kerresh closed, Huron Blackheart fought with a ferocity even Rotaka had never seen before. The last Cadians refused to die easily, even as the closing Archway left them stranded to face their deaths, and clustered together, firing everything they had at the Tyrant. Blackheart ran into a dozen of them, taking las-shots at point-blank range, even batting aside a rocket with the Tyrant’s Claw. The blades of that claw crackled as they sliced through mortals, and the bayonets of Guardsmen shattered against Huron’s armour.

This is madness, thought Rotaka, as if madness were somehow alien to Huron Blackheart. He ran forwards in his master’s wake, bolter firing on mortals aiming at his lord, but as he did so Rotaka thought – what if he succeeds? How does he think that will work? Huron Blackheart was a giant amongst even Space Marines, possessed of a titanic will, but even he couldn’t survive without allies with an entire planet and its armies set against him. Alone, on Kerresh, he would surely die.

And yet Huron Blackheart fought off his assailants and tried to push on. Their attempts to cut him down were futile – Huron was as much machine as man, and both those parts were blessed with unholy power. They died, every one of his attackers, but they also succeeded in delaying Huron enough.

The portal to Kerresh closed. Rotaka caught a glimpse of something impossible, a figure throwing themselves from above, through the last gasp of the portal, a dark speck against the swirling otherness – and then it was gone, and there was nothing but the empty Archway.

And with it, the last will to defend themselves seemed to fall from the defenders of the Archway. Huron cast his assailants aside with ease, and those who did not die from the impact were cut down by the other Corsairs, who surged forwards unimpeded.

Within seconds the mortal defenders of the Archway were all dead.

But it was too late.

Huron Blackheart stood, looking up at the empty Archway, silent and entirely still.

Through the crowd of Corsairs, Garreon seemed to almost glide to his master’s side, unconcerned by anything around him.

‘My lord,’ Rotaka heard the Corpsemaster say. ‘This is nothing but a delay, Valth–’

‘I do not have time for delays,’ Huron shouted, the Tyrant’s Claw locking around Garreon’s neck, charging through the ranks of Red Corsairs who parted like a sea, slamming the Corpsemaster into a wall, which began to crack with the impact. Huron’s organic eye was manic, wider than usual, twitching, his mouth twisted into a quivering grimace.

And, just for a second, Rotaka saw something else, something more than his master’s rage, a deeper distortion at work within Huron Blackheart. He saw Huron’s corpse-grey flesh bubble impossibly into scales and green, wet amphibious flesh and even a crop of purple feathers and a hard red carapace, and that mouth stretched down and split into tentacles and small claws that would scrape food down into an open cavernous mouth, and Huron’s eyes… Huron’s eyes were many and black and milky white, with vertical pupils and horizontal pupils and every colour of iris, and his limbs were many and sprouted into a great flower of blades and claws and tentacles and…

…and it was gone, and Huron was Huron Blackheart, master of the Red Corsairs.

Rotaka glanced from side to side, his wavering gaze hidden by his helmet. If anyone else, Corsair or mortal, had seen what he had just seen, they didn’t react to it.

‘My lord,’ hissed Garreon, his voice strained through the chokehold. ‘You will have these worlds, and you will have them in time.’

Huron dropped the Corpsemaster and scowled, turning his gaze to his other subordinates. The Red Corsairs did not flinch as the Tyrant’s gaze swept across them, but even the most debased and corrupted of the human slaves backed away, heads bowed in terror.

‘Anto,’ Huron snapped to the sorcerer. ‘Give me better news, to relieve this… disappointment.’ He spat the last words out like poison in his throat.

‘All is not entirely lost,’ said Anto, beginning a conversation that Rotaka could no longer hear as the Tyrant and the sorcerer walked away, deep in muttered conversation.

Garreon, seemingly unfazed, also drifted away, as did the other officers. There was much to do. But Rotaka needed to filter his thoughts. What had he just seen? He trusted his own senses, stretched as they had been by life in the Maelstrom, and knew when the warp pushed against the skin of the conventional universe, threatening to break through.

The key lay in Huron and Garreon’s heated exchange of words. Huron had said that he didn’t have time. Impatience and egotism were part of Huron’s personality, and with unswerving loyalty Rotaka would never question the Blackheart’s right to treat the Red Corsairs as an extension of his will and desires, their achievements a mere reflection of his own brilliance. But this was something more than a mission of conquest; there was a rawer motive beneath Huron’s words, something personal.

And Garreon’s response. Chillingly, the Corpsemaster’s words hadn’t been evasive or defensive, but reassuring. The idea that his master needed the soothing words of the likes of Garreon shook Rotaka’s sense of himself.

A Space Marine, even one who had rejected the Emperor and submerged himself into the wildness of Chaos, rarely knew uncertainty, but Rotaka knew it now. He had thought this a campaign of conquest, but the intense exchange between Huron and Garreon suggested some other purpose.

If they were not on the Hollow Worlds to conquer them, what were the Red Corsairs doing there?

Out in space, Pranix’s escape pod continued on its course, taking the slow, warp-free journey to find aid, its passenger as much a prisoner to his own decision as anything else, unable to alter its course.

Alone, he was the only hope the Hollow Worlds had for liberation.

Part Two

Twelve

165 days later

The train never stopped. Five storeys high, longer than most settlements on the Hollow Worlds, its armoured sides hanging low over the edges of the planetary ridges on which it rode, it was a monstrous, heavily defended machine that kept moving, was almost impregnable and near unstoppable.

Rotaka and his squad intended to board it.

The Red Corsair stood at the top of a captured refuelling tower. The planet was so heavily forested that the trees even rose above the level of the ridges themselves, and towered over the habs in Plini’s populated regions. The canopy of the forest cast a dapple of shadows over the featureless metallic stretch of the ridge.

Rotaka eyed the countdown in the corner of his helmet display. It would not be long now – it had taken weeks to assemble the information and work the calculations to predict the passage of the train, which could even navigate the intersections of the ridges, allowing it to travel virtually anywhere on the grid.

Now they were here, and it came to this – Rotaka’s reaction times, and a hook on the end of a super-strong, highly flexible beam.

The seconds were counting down. Either this would work, or he would be torn in half in the attempt. Or, even worse, if the calculations were wrong, they could miss the train altogether, and he’d have to explain his failure to Huron.

The beam Rotaka was holding was connected to a harness strapped around his power armour, which in turn was connected to a length of retractable high-tensile cable that connected Rotaka to Hulpin, who was in turn tied to Verbin, who in turn… and so on, the entire squad linked in a chain.

In theory the momentum would carry them to–

But there was no more time to dwell on the theory, as in the distance something was moving down the ridge towards Rotaka, hurtling forwards. A low rumble could be heard, enough to cause a flock of red-and-blue birds to fly out of the canopy overhead and sweep down into the depths of the forest, chirruping alarm as they went.

Rotaka raised the beam with the hook on the end to exactly the right height and position, and tried to slacken his muscles as much as possible. A Space Marine’s superhuman strength was an incredible asset, and one of the reasons he might even survive this, but being too rigid when he encountered an unstoppable force would simply break him.

It came, a great beast of metal moving at incredible speed.

Time for a single breath. Rotaka found some calm within himself, allowed time to slow around him, to let himself relax within the protective confines of his power armour.

The train passed them. The hook caught the loading scoop, and Rotaka was whipped off his feet at tremendous speed. As the beam went taut, he bashed into the side of the train, the cable threatening to tear him in half as it jerked Hulpin off his feet.

Rotaka was being pulled along so fast he was horizontal, trailing like a paper ribbon along the side of the train, an insect clinging on to a behemoth.

He had a matter of seconds to act before the weight of the Red Corsairs following him pulled him apart.

Slamming repeatedly into the side of the train, the rush of air turning his helmet’s auditory sensors into a blur of white noise, Rotaka took a magnetic clamp and slapped it onto the side of the train. Then, holding on to the clamp, he braced his boots against the train’s shell, the soles magnetically locking to the near featureless surface of black-grey metal. Finally, he let go of the beam and used his free hand to push a mechanised pulley reel on the cable into the train, thumbing a red button on the side so that it drilled a hole and locked itself in place, a flurry of metal filings whipping away into the distance.

Secure, clinging to the side of the train, Rotaka looked back. His squad had all secured themselves, Hulpin having dug in with his chainfist and the others locking themselves in place as Rotaka had. The cable that connected them trailed down the side of the train, fastened in multiple places.

‘That actually worked,’ said Rotaka in disbelief.

‘You should have more faith,’ growled Hulpin over the vox.

Rotaka checked the display in his helmet, which had switched to a different countdown the moment the train passed their initial position.

‘Tunnel in three minutes,’ said Rotaka.

Letting the cable extend with him as he went, Rotaka pulled himself up the beam hand over hand, then re-secured the cable next to the hatch the hook had caught itself on. This was a supply scoop, which would snatch bags hanging by the side of the line – a primitive but effective way of getting supplies onto the train without it stopping, and the train’s only vulnerable point.

Rotaka disconnected the beam from his harness, then pulled the grapple away from the scoop. He threw the whole contraption away from the train and it fell into the jungle.

Looking at the chute behind the scoop, it was big enough to accommodate a large sack, or even a human, but there was no way a fully armoured Space Marine would fit through such a narrow tube. Bracing himself against the side of the train, Rotaka held the lip of the chute with one gauntleted hand and tried to manually force it away.

He strained, but it didn’t work – the outer lip of the scoop was bent out of shape in Rotaka’s grip, but the shape of the chute as a whole wasn’t affected. ‘I’m going to have to blow it,’ he voxed. ‘Stay back.’

Making sure he had a tight grasp on the cable, swinging experimentally before he did so, Rotaka set an explosive charge with a short fuse and chucked it straight down the chute.

He hoped that the tube didn’t take the charge too deep into the train, or damage the vehicle’s outer shell.

The explosive gone, Rotaka shuffled back down the train along the cable, hand over hand, boots scraping the side of the vehicle as he shifted his huge weight along.

The explosion barely shook the train. A plume of flame and debris was caught by the wind and thrown back down the length of the train, a chunk of flaming metal narrowly missing him. Smoke was left trailing out of a hole in the side of the train, one frayed with bent flaps of blasted metal.

Rotaka shuffled back towards the gap in the train’s shell, looking up to see the mountains approaching ahead. Clinging to the side of the train one-handed, he blind-fired his bolter into the hole a couple of times, to discourage any defenders.

Reattaching his bolter to his thigh, Rotaka swung around to look in the hole. It was still slightly too small for a Space Marine to slide through, and the mountains were looming fast.

He swung back along the cable, gathered some momentum, and gave one of the flaps of metal protruding from the hole a two-footed kick. It shifted slightly from the impact, but didn’t move enough to expand the hole. Rotaka rebounded from the kick, and had to scramble his heavy boots against the wall of the train to stop himself from falling.

The mountains were nearly upon them. Rotaka took a bigger swing, detaching the safety cable from the wall of the train, and launched himself at the flap of metal, slamming into it with his entire body weight.

The flap tore backwards, ripping a larger hole in the side of the train. Rotaka slipped downwards and had to grab on to the eye sockets of a decorative skull to not fall further.

Looking up, he could see the hole was big enough now.

‘In, now,’ he voxed. ‘I’ll follow.’

Hulpin scrambled across to the hole, punching handholes in the side of the train with his chainfists along the way, and threw himself in head first. Before his boots had even disappeared, Verbin was doing the same, then Malinko.

Wuhrsk took hold of a ridge of metal above the hole and slid in feet first, grabbing the safety cable and pulling it in. Rotaka, swinging at the end of the cable, let go of the secure hold he had on the skull and scrambled up the sheer metal surface, his hands reaching out to Wuhrsk, who grabbed his wrists.

‘Pull!’ Wuhrsk shouted over the vox, and Rotaka was pulled in, his heavy, power-armoured form scuffing through the ragged metal hole and into the open interior of the train. As his heels passed into the interior the train reached the tunnel; a wall of rock smashed the rough edges off the hole they had just entered.

Rotaka looked back. Outside the hole there was nothing but the dark of the tunnel, rock passing a couple of inches from the outside of the train.

‘Tight fit,’ he said, as Verbin pulled him to his feet. Wuhrsk was firing up the corridor at unseen targets, while in the other direction – towards the rear of the train – the way was blocked by wreckage from the explosion.

‘Where now?’ asked Hulpin.

‘Our mission objective will be at the head of the train,’ said Rotaka, removing Iltz from his carrying harness and reactivating the servo-skull. He gestured for Wuhrsk to lead the way.

The interior of the train was decorated in the more decadent styles of the Imperium, bejewelled skulls inset into walls draped with dark velvet tapestries. The relative opulence indicated the status of the train’s main passenger, who was kept in such luxurious imprisonment to prevent the ever-changing knowledge he or she possessed from being captured. Even the system governor could only contact the passenger via vox, and the on-board staff had been interbreeding new generations for hundreds of years.

It was just as the official they captured on Laghast had described it, a perfectly sealed system.

The carriage had a series of cabins on the right. Some of them had open doors with dead men and women lying in the doorway where Wuhrsk had gunned them down. Most looked locked. The squad kept them covered as they moved down the corridor, but there were no further attacks, and no sign of life.

Rotaka looked down at the dead. They all had the same reddish-brown hair colour, light brown skin and bright blue eyes. Clearly the gene pool wasn’t deep enough amongst the retainers who staffed the train, thought Rotaka, aware that if he, one of many battle-brothers made physically similar by gene-seed descended from the same primarch, noticed evidence of in-breeding then it must be bad.

They moved through a deserted, open carriage decorated with wood panelling and littered with small shrines. Iltz floated around, scanning little nooks and corners out of Rotaka’s visual range but raising no alerts.

‘I don’t think much of their serfs,’ said Wuhrsk, shaking a thick layer of dust off a parchment before tossing it aside. ‘I’ve seen tomb worlds kept in better repair than this place.’

‘The stifling order of the Corpse-Emperor’s Imperium can only lead to decay and degradation,’ intoned Hulpin.

‘Thanks for the sermon,’ said Rotaka. He suspected that the Imperium generally ordered its assets to be kept in better repair than this, and that the poor state of the train was due to the mental decay of the on-board crew rather than some theological failing, but he wasn’t going to rile Hulpin by saying that aloud.

Entering the next carriage they found a single open space broken up by ranks of tall bookshelves. Watery light filtered down between the shelves, sunlight seeping through dirty windows in the roof above. Ladders and balconies allowed the retainers to access all books.

It was the perfect place for an ambush, and as the Red Corsairs entered they were fired upon from all directions.

Rotaka led his squad through the room, firing their bolters on retainers as they emerged from behind the shelves or fired down from the balconies above. Just ahead, four retainers were rolling a mounted plasma cannon into position.

Verbin ran past Rotaka, punched the nearest mortal away from the heavy weapon and grabbed it. He didn’t bother to detach it from its tripod but instead swung the whole rig towards the other three retainers and fired. The plasma bolt, fired at near point-blank range, obliterated the three retainers and blew a hole in the side of the train through which another couple of retainers obligingly fell.

As Verbin fired, Malinko swung his flamer around to ignite the last of the retainers.

‘Keep pushing ahead,’ said Rotaka. ‘Verbin, bring the cannon just in case. I don’t want to crash this train until we’ve got what we came for.’

Verbin nodded, tearing the plasma cannon from its tripod and using a long strip of leather to sling the weapon over his back.

In the next carriage, Rotaka found a small group of retainers, one aged and wearing a more elaborate uniform than the rest, setting explosives at the connecting, concertinaed section between this carriage and the next.

Wuhrsk and Hulpin gunned down the other retainers while Rotaka grabbed the most senior one by the throat.

‘You’re too late,’ hissed the old man through Rotaka’s grip. ‘The charges are set. The explosion will be any second.’

‘Fine,’ said Rotaka. ‘We don’t need the rest of this train anyway.’

The old man looked confused, then disappointed, then horrified, all in the space of a second. Such fleeting, stupid mortal emotions, thought Rotaka.

He was about to crush the man’s throat, when he paused.

‘Where are your children, slave?’ Rotaka asked, releasing his grip.

The old man’s fear turned to terror. ‘What?’ he asked.

‘The children,’ repeated Rotaka. ‘We know your family has been on board for generations. Where are the children?’

‘I will not tell you,’ said the old man.

‘Very brave of you, so let me guess – they’ll be at the rear of the train, where they cannot disturb your passenger,’ said Rotaka, picking up the old man by the arm, dragging him to the intersection with the library carriage and throwing him in.

‘Live and tell them of your failure as they grow, old man,’ said Rotaka. ‘By the time you work out how to climb down from this rail these worlds will be ours, and your descendants will know new masters. Prepare them for a life serving the Red Corsairs.’

The old man ran off between the shelves, Rotaka’s last words echoing after him.

The Red Corsairs moved into the front carriage of the train. Shortly after, they heard an explosion. Rotaka looked back to see the rest of the train disappearing behind them, slowing to a halt as the front carriage and the engine kept moving.

They were left in an elaborately decorated corridor, tiled in black stone edged with gold, leading to double doors of carved red wood. The Corsairs burst through those doors to find a single passenger, their target, waiting quietly for their arrival.

Once, he may have been a mortal man like any other. Now, he or she – it was hard to tell – had grown huge, and was plugged into the machinery around them with countless tubes and wires. The ends of these attachments disappeared beneath rolls of pallid, aged flesh. The head of this creature was little more than a lump of pasty meat set upon a much larger lump of pasty meat, the folds of eyes and mouth and nose only barely different to all the other folds on its body, a mere wisp of hair clinging to its bald scalp. He resembled nothing less than a bloated, extremely complex servitor.

‘Welcome, traitors,’ said the passenger. It was a heavily modulated voice, and it came from the walls all around rather than the body of the passenger itself.

‘Red Corsairs,’ corrected Rotaka, bolter at the ready. Who knew what capabilities this thing had to defend itself? It could even be a psyker.

The passenger shrugged, a tidal wave passing through its flesh.

‘When the communications were disrupted, I knew the Hollow Worlds were under attack,’ said the passenger. ‘I hoped your invasion would bring you this far.’

‘Hoped?’ said Rotaka. ‘Do you know who we are?’

‘Traitors, as I said,’ said the passenger. ‘Killers, murderers, despicable scum.’

Hulpin growled and lifted his bolter. The others looked restless too.

‘Control yourselves,’ Rotaka snapped over the squad vox, not knowing if the passenger could hear them or not.

The passenger raised one great, flabby arm in a dismissive wave, and a chuckle emerged from the surrounding speakers.

‘You would not want to kill me yet, traitors,’ said the passenger. ‘Not until you have what you want from me, at least. Do not let wounded pride rob you of your prize.’

‘You know what we want?’ asked Rotaka.

The passenger sighed. ‘What else, but the only thing I have,’ he said. ‘Apart from my train, and its crew. And you seem to have broken those.’

The mass of flesh leaned forwards, and its mouth suddenly opened, black tongue licking dry lips.

‘You want to access the Orrery,’ croaked the passenger’s true voice, quietly.

‘Then give us what we want,’ said Rotaka. ‘And your death will be quick.’

‘Of course,’ said the passenger, reverting to its artificial voice. ‘It is my purpose to sit here, knowing the code. I and my brother, the gateholder, are in perfect synchronicity – whatever I imagine the code should be, he imagines also. For that to work, they let us retain our imaginations. If they mutilated our minds the system wouldn’t work. Can you understand what it is to be trapped like this, your suffering only limited to your imagination?’

The passenger was ranting now, furious. No wonder he would give up the secret so easily – he hated the Imperium and the authorities that had put him here; he would happily help the Corsairs burn the Hollow Worlds.

‘The code,’ said Rotaka

‘Two words,’ said the passenger ‘Two words my brother and I will both think, watching your invasion from afar, trapped in our twin prisons, only able to–’

‘Spare us your self-pity and just tell us the damn code,’ barked Malinko. ‘Before I torture you out of sheer boredom.’

‘Poisoned chalice,’ snapped the passenger. ‘The code is “poisoned chalice”.’

He looked straight at Rotaka, and again Rotaka wondered if the passenger was a psyker, if he knew about the vision from the Cup of Blessings.

The passenger opened his mouth again, but before he could speak Verbin fired a plasma bolt into the bloated human, obliterating its head and cleaving a burning gash through most of its torso. Thick, dark blood dribbled out of the gaping wound and began to spread across the floor in a pool.

‘Conversations,’ said Verbin dismissively, and the others just grunted in agreement.

Various warning lights began to flash around the room, and the main lights went red.

‘Verbin, let’s have an exit here,’ said Rotaka, deactivating Iltz and tucking the skull away again.

Verbin nodded, and blasted a hole in the side of the train with the plasma cannon.

‘I’m starting to like this thing,’ he said, hefting the weapon in his grip and admiring the hole. ‘Can I keep it?’

‘Knock yourself out,’ said Rotaka. ‘Speaking of which, Malinko, this looks like your sort of fun.’ Rotaka gestured to the sheer drop outside the train.

‘Thank you,’ laughed Malinko, and then he ran at the hole Verbin had made and leapt out of the train, falling down into the depths of the forest, jump pack firing to slow his descent.

Running towards the hole himself, the rest of his squad just behind him, Rotaka heard Malinko’s gleeful laughter echoing over the vox all the way down.

Thirteen

Laghast had been a world of still seas and skies a few weeks before, but now it was a world of fierce, unnatural storms, and the worst of these disturbances were centred around the Archway to Kerresh. Since Valthex and Anto reopened the Archway, the city of Rubicon had been plagued by burning rain, purple-red lightning that danced across the ground as if searching out targets, and hailstones large enough to kill a man.

Huron Blackheart’s command centre was near the Archway, in the shadow of the generator his Chief Techmarine and the Tiger Claws sorcerer had created between them. The command centre was based in old Imperial buildings, the aquilas stricken out with crude red crosses. The walls were marked with symbols of Chaos, the floors and surfaces covered in maps and battle plans, the corners laden with trophies.

But when the storms came the Tyrant rarely stayed indoors; instead he was often to be found at the heart of the storm, standing near the Archway, the blades of the Tyrant’s Claw almost touching the incandescent surface of the portal to Kerresh.

That was where Valthex found him, standing in front of the portal as icy rain lashed down from turbulent skies, gathering in dirty puddles across the muddy courtyard. He had found him here many times. While the Red Corsairs spread their influence to other worlds, Huron commanded from this one city, seemingly reticent to enter the Archway, but fascinated by it. He stood there, a shadow against the light of the portal, his dark presence heavy.

After his rage at the delays, Huron had been entranced by the Archway once it had reopened, and had paid Valthex what sounded remarkably like a compliment.

‘The point of transition,’ he had said, standing before the Archway as he did now. ‘You and Anto have created a remarkable uncertainty here, Valthex. The point of change between one thing and another.’

Now, Huron was silent, and Valthex had to speak to gain his attention.

‘News from Captain Rotaka, my lord,’ said Valthex reluctantly. It was never entirely safe to disturb Huron Blackheart. ‘Access to the Orrery is ours. We have a precise location and the code to enter.’

‘Show me,’ said Huron Blackheart, turning to Valthex. Rain dripped down his face, flowing down the deep channels in his grey, dead skin.

They entered Huron’s command centre, water dripping off them over a cracked tile floor. The room was empty apart from two servitors awaiting instruction, but Valthex knew Huron’s bodyguards would not be far away. There were many maps on the central table, but Valthex projected an image on the wall.

‘Here, my lord, on the planet Karstveil,’ said Valthex. ‘There is a desolate island, on the far side of the world from the Archway, surrounded by turbulent seas. The localised weather effect may be artificial, part of the defence systems.’

Huron Blackheart was silent, staring at the nondescript blob on the map.

‘Shall I tell our spearhead on Hacasta to move immediately to Karstveil, my lord?’ asked Valthex.

‘No,’ said Huron Blackheart, his white eye filled with a predatory hunger. ‘Tell them to hold position and wait for my arrival. I shall take the Orrery myself.’

As a girl, Sergeant Anju Badya of the Tallarn desert raiders had seen the aftermath of an entire city collapsing, and had hoped to never see such a densely packed population of humanity again. Then she and her squad rode out onto the platforms high above the surface of Trincul, and saw the refugee camp.

Trincul was a world of flatlands, its Inner Dock a raised city of metal platforms overlooking the dire swamps. As the Tallarns deployed into the Inner Dock, Badya looked out across a refugee camp that stretched to the very horizon, an endless sprawl of makeshift tents and huts.

‘They have been coming here since the invasion began,’ a Jandarme told her. ‘All the ships have gone, but still they come.’

‘What do they eat?’ asked Badya.

‘I don’t know,’ said the Jandarme, his face covered by his cap as he stood next to her horse. ‘Each other, perhaps?’

Anju made a non-committal noise, and the Jandarme wandered off.

Sergeant Badya and the rest of the Tallarn 14th, along with many other forces of the Imperium, had been in the final days of a long campaign against the ork when the inquisitor had fallen from the sky. A few days later she had seen Pranix in person, addressing the gathered forces and tasking them with liberating the Hollow Worlds. He had inspired her then, standing on a tank in full robes and wielding a staff, but seeing the scale of what they faced…

Of course, the Tallarns did not face this threat alone. There had been other forces fighting on Durrl, and Anju had no doubt it was their aid the inquisitor required most.

To Lord Cheng’s disgust, the governor of Trincul had disappeared shortly after the invasion began, the suspicion being that he had bribed his way out of the system to destinations unknown. In his flight he had left his palace to the mob, and when Lord Cheng and his retinue arrived to establish their base of operations there, they found it crowded with refugees.

A formal invitation had been extended to Inquisitor Pranix, requesting he meet the system governor there. As Cheng’s servants set out the maps and charts of the system governor’s war room in a heavily vandalised dining hall, the sound of screams and occasional gunfire could be heard as the Jandarme drove starving refugees out of the rest of the palace.

Kretschman watched and listened to all this, his new dress uniform unnaturally comfortable. He felt exposed. In Inquisitor Pranix’s absence, Lord Dumas Cheng had summoned Kretschman to Ressial and his court, to act as some kind of substitute for the inquisitor. It was a role Kretschman was poorly qualified to fill, but Cheng wanted to know what little Kretschman knew about Pranix, and Lieutenant Nistal seemed glad to be rid of a sergeant who had now walked away from two massacres intact.

So Kretschman had become an unlikely liaison to the system governor. Cheng had interrogated him long into the night about Pranix, the Red Corsairs’ methods, and what little Kretschman knew of previous engagements with Traitor Marines. He had even had Kretschman try to instil some Cadian wisdom in the senior officers of the Jandarme, an embarrassment for both the veteran sergeant and the weathered commanders ordered to listen to him.

Now it was Pranix who Cheng put all his hopes in. The system governor had set out for Trincul – the Lightward entrance to the Hollow Worlds, a gateway to relatively untroubled, secure Imperium-held space – the moment word came in of a large task force of Space Marines landing at the Lightward Gate. The power of their drop pod assault had left the algae-covered surface of Trincul a cratered mess. It was an act of desperation, to Kretschman’s mind, but it was consistent with Cheng’s behaviour in the weeks since he had arrived at the Gatehouse on Ressial. Cheng was determined to impress Pranix, even though Kretschman knew the inquisitor would not hesitate to take full control of whatever power Cheng still held.

When the inquisitor arrived, it was with no fanfare, although considering the company he now kept he didn’t need it. Kretschman was surprised to see Pranix had abandoned his modest garb in favour of full Inquisitorial regalia, although Pranix seemed exactly as comfortable in his full finery as Kretschman did in his.

More striking still were his companions. They were Space Marines, far less monstrous than those Kretschman had seen on Laghast, but no less dangerous. Bearded and draped in furs over their armour, they had an alert, feral presence, and Kretschman had no doubt they could tear his new arm off and smack his head in with the shoulder joint without the slightest effort or hesitation. They towered over the mortals in the room, and only Pranix seemed less than intimidated by their presence.

No wonder – they were Space Wolves, legendary even in the annals of the Adeptus Astartes, feared by all enemies of the Imperium. They gave off a strong animal stench. Their beards and hair were thick and matted; black pinprick pupils stared out from bright yellow irises.

Each of them had one pauldron emblazoned with an icon of a wolf skull against a crescent moon. One stood even taller than the others, his jaw thicker and hair whiter, his armour edged with gold and the outline of a golden wolf’s head on his breastplate. The moonlight caught the pommel of his silvered chainsword, on which a gauntleted hand rested. His silvery hair flowed long, seemingly merging with the wolf pelt draped over his shoulders. Everything about him indicated he was the leader of the Space Wolves.

‘Lord Cheng,’ said Pranix, breaking a stunned silence.

‘Lord Inquisitor Pranix,’ said Cheng, recovering his posture. ‘Thank you for accepting my invitation, and for coming to the aid of our Hollow Worlds in this most desperate hour.’

‘An honour, system governor,’ said Pranix, continuing the formalities. ‘May I introduce Wolf Lord…’

At which point he trailed off, staring at Kretschman.

Inquisitor Pranix seemed genuinely, speechlessly shocked.

And that shock in turn shocked Kretschman.

‘Veteran Sergeant Kretschman,’ said Pranix, ignoring the system governor and the towering Space Marines. ‘What a distinct surprise to see you here, after I left you on Laghast. I expected you to be out there somewhere, with your regiment.’

‘I would have expected that too, my lord,’ said Kretschman, aware that he was the centre of attention. ‘Yet my orders have brought me here.’

‘You seem to have an uncanny ability to gravitate towards the centre of events, Kretschman,’ said Pranix, an odd look in his eye.

‘I assure you, my lord, it was never my intention to do so,’ Kretschman replied, trying to seem as modest as possible.

‘Yes,’ said Pranix. ‘I think that’s true.’

Then he turned back to Cheng.

‘Apologies, my lord,’ said the inquisitor. ‘Let us discuss matters of strategy, if we may…’

While their jarl discussed strategy with the inquisitor and system governor, nearby the rest of the Space Wolves had raised their encampment. Kaerls ran back and forth on errands for their masters, the air filled with fumes as the engines of tanks were tuned and tested, and everywhere, the Sky Warriors, the Vlka Fenryka, the Space Wolves, gathered around fires, drank mjod and told stories as they always had.

Anvindr Godrichsson and his pack were in no mood for stories. They had been restless since Durrl, when the inquisitor had fallen from the sky. On the inquisitor’s word their jarl had left his second, Gunnar Redmoon, and a small force to finish their work on Durrl, and had led the rest of the Skull Wolves to the Hollow Worlds.

Pranix. Anvindr and his pack had met him once before, in Hrondir’s tomb on Beltrasse, back when he was an interrogator serving Inquisitor Montiyf. Together they had destroyed a daemon that stalked the catacombs, but not before the daemon had killed one of their pack, Liulfr. Montiyf and Pranix had known of the daemon before, and suspected where it hid, and Anvindr had always believed that by guarding their secrets so closely, the inquisitor and interrogator had allowed Liulfr and many mortals to die unnecessarily.

Anvindr and his pack were older and greyer, but the circumstances of Liulfr’s death had haunted them through many battles since.

That Pranix had re-entered their lives, to lead them no less, seemed a bitter insult from fate.

So the pack sat around a campfire in silence, while their brothers celebrated battles past and the battle to come.

‘It gladdens me to see us all enjoying the open sky after our long confinement,’ said Sindri. Unlike Anvindr, whose heavy features were framed by a white-streaked beard and long hair, Sindri was slight for a Fenrisian, his hair a tight shock of blond curls. Although he lacked the lengthened fangs that usually showed a Space Wolf brother’s maturity, there was no denying Sindri’s experience in battle and warrior spirit.

By Russ though, Sindri’s odd humour was the last thing Anvindr wished to face right now.

‘This discussion is futile,’ said Gulbrandr, without looking up from polishing his bolter. Gulbrandr’s raven-black beard had fangs of white streaking down to the chin now, but his pale skin was still as impassive as marble, his amber eyes as sharp as flints.

‘What discussion?’ asked Sindri, throwing up his gauntlets. ‘We discuss nothing.’

‘Nothing to discuss,’ rumbled Tormodr, the largest of the pack. His mouth was barely visible beneath his thick moustache, his eyes shadowed by his heavy brow. Tormodr rarely spoke, but when he did even Sindri listened.

‘Tormodr is right, the jarl has spoken,’ said red-headed Hoenir, gesturing with his scarlet-painted power fist. Hoenir, lone survivor of his own pack, had joined them years ago, and was no young Blood Claw, yet his presence in place of Liulfr surprised Anvindr still.

‘And yet somehow I feel there are words unspoken still,’ said Sindri, his words dripping with sarcasm.

Nevertheless, Sindri sat down and joined them in silence, defeated.

It was true that Anvindr had spoken with his jarl, Haakan, in his tent while the injured inquisitor slept, back on Durrl. He had recounted the events of their last encounter with Pranix, of how Pranix’s secrets had allowed Liulfr and many mortals to die at the claws of the daemon in Hrondir’s tomb.

‘Did you kill the beast?’ Haakan had asked.

‘We did,’ Anvindr had replied. ‘The inquisitor, and Pranix, and the rest of my pack. Together we destroyed that filthy thing.’

‘Together,’ Haakan had repeated.

‘Yes,’ Anvindr had said. ‘None of us could have butchered it alone.’

Haakan had sat back. The light caught his sunken eyes, lamplight reflecting from his pupils.

‘We are the Rout, Anvindr, you know our accounts,’ he had said. ‘We were chosen by the Emperor not simply because we would slaughter traitors without mercy, but because we would do so relentlessly, without reservation. We show no mercy to the enemy but, when our orders demand it, neither should we show mercy to ourselves. You lost a brother due to this Pranix, but that was one loss on the way to your enemy’s defeat. We do not have to like the tactics to see the necessity of the outcome.’

‘Such subterfuge is not our way,’ Anvindr had said, trying not to let defiance slip into his voice. He kept his head low, avoiding Haakan’s gaze.

The jarl had let out a low growl, a threat that kept Anvindr’s head down.

‘Our ways are our ways,’ spat Haakan. ‘We have our own honour and our own code, and we pity and hate those mortals and others who live by lesser creeds. But the Inquisition is an instrument of the Emperor, also. They have their own codes that are not ours, but to live with honour we follow their orders nonetheless. Go, take your doubt and crush it as you would any enemy.’

‘I recognise my failing,’ Anvindr had said as he crossed to leave. ‘And will be sure to correct it.’

‘You do that, Anvindr Godrichsson,’ Haakan had said. ‘And remember that, should we be led astray by another’s foolish whims… Well, the Emperor’s will has a way of correcting that, too.’

Those had been dangerous words for even a jarl to utter, and they were the one part of the conversation Anvindr had not repeated to his pack. Sitting staring into the fire, those words calmed Anvindr’s silent rage a little, the slim promise that Pranix might face a reckoning still.

Following the sacking of Rubicon, the temple to the Emperor had been desecrated in the vilest ways, its statues and shrines smashed and befouled, blood and other fluids smeared across every surface, dried to a crust over the weeks since then.

Anto had made it his home on Laghast. The inversion of the sacred space’s purpose, smashing its symbols and reconsecrating it to his own gods, pleased the sorcerer. This blasphemy against the Corpse-Emperor, the false god who Anto had long rejected even before Huron’s conversion, made the temple a perfect ritual place.

Fresh blood had been spilt, straight from the veins of many members of the Ecclesiarchy captured for just this purpose, flowing through grooves Anto had personally, painstakingly chiselled into the stone floor. Incense burned in the Cup of Blessings.

Anto sat in the centre of the blood-symbol, the cup before him, its smoke rising to his nostrils. Huron knew his purpose, and would not disturb him in his meditations. No one else would dare try while he was on the Tyrant’s business.

He breathed deeply, loosening his mind’s connection with physical bonds, not to drift but to move with purpose, his consciousness reaching out, pushing through the Archway and the Archways beyond, reaching out across worlds, trying to make contact.

Kretschman watched as the system governor showed Pranix and the Space Wolves the pride of his war room, the great maps of the Hollow Worlds of Lastrati, placed across seven tables, the latest reported forces represented by models scattered across each map. Red Corsairs units had spread out from Laghast, through the Archway to Kerresh. From there they had advanced on Kerresh’s Archway to Hacasta.

‘The Archenemy have spread far,’ said the leader of the Space Wolves, looming over the maps. Pranix had introduced him as Wolf Lord Haakan of the Skull Wolves, and his voice was a deep bass rumble, weary with years. His beard was whiter than those of the other Space Wolves, his lower face extended into something closer to a muzzle, and heavy fangs filled his mouth.

‘It is worse than I expected,’ said Pranix. ‘Did the Cadians close the Archway between Laghast and Kerresh?’

He looked directly at Kretschman as he asked the question, but it was Cheng who answered.

‘They did, my lord, but the traitors reopened the Archway within weeks,’ said the system governor. ‘Our forces had prepared a pre-emptive strike to retake the Archway when it opened, but it was crushed.’

Lord Haakan growled contemptuously. ‘And now they run amok across the system,’ the Wolf Lord spat.

‘The Cadian Three Hundred and First have made sporadic guerrilla attacks to slow the enemy’s advance, my lord,’ said Cheng, with the tone of a man feeling the rope tighten around his neck.

‘Fascinating, such fine detail,’ said Pranix, picking up a model of a Red Corsair representing a sighting of a Red Corsairs unit, examining it closely then putting it down exactly where he found it on the map of Kerresh. Then he turned to the two lords, the system governor and the Wolf Lord. ‘Let us not dwell on existing defeats, but on how to reverse them.’

This seemed to cast the Wolf Lord into deep thought, his grey eyes distant as he stroked his beard with one gauntleted hand, surveying the maps.

‘This world, Hacasta, is gateway to the others,’ Haakan said. ‘Once taken, they will have access to your throne world, and the whole system. How close are they?’

‘We believe the traitors have taken the Hacastan Archway and made advances into Hacasta, my lord,’ said Cheng. ‘But only in the last two days–’

The Wolf Lord silenced him with a glance from his golden eyes.

‘Inquisitor, your ordo has studied the traitor Huron Blackheart,’ said Haakan, his words sounding more like an accusation than a simple statement. ‘Where will he strike?’

If Pranix was troubled by Haakan’s tone, he concealed it well.

‘Blackheart seeks power and conquest,’ he said. ‘He will wish to capture Ressial, the throne world. These Traitor Marines may seem like mindless monsters, but they are heretics and their twisted faith is soaked in signs and symbols. Even if there is no urgent strategic need, Huron Blackheart will wish to seize the seat of government within the Hollow Worlds as a symbolic taking of power. If we can deny him that, his occupation of other worlds will be less secure, both to his forces and the inhabitants of the occupied world.’

The Wolf Lord gave a grunt of assent.

‘The throne world will be defended,’ said Haakan, then belatedly, ‘as the inquisitor wishes it.’

His eyes moved across the map.

‘What is this island?’ he said, a finger coming down on the map of Karstveil, between models representing forces deployed. ‘“Ironshore.” It is as well defended as your palace. Why?’

Cheng seemed hesitant, then began to speak, only for Haakan to snarl.

‘I can smell the lie on you before it is uttered,’ spat the Wolf Lord. ‘I have not lived so long without learning the scent of mortal deceit.’

Kretschman found he had unconsciously taken a step backwards, recoiling from Haakan’s restrained fury.

‘Wolf Lord Haakan is one of the Emperor’s Adeptus Astartes, while I am of the Holy Inquisition,’ said Pranix. ‘There is no secret so sacred we are not entitled to know the truth of it.’

‘The Orrery is a device capable of altering the alignment of the Archways, to alter the connections between the Hollow Worlds,’ said Lord Cheng. His voice had taken a hushed, almost resentful tone, as if he hated to speak out loud the secrets of his office, even to superior authority and with dire necessity. ‘It hasn’t been used for millennia, since the calamity which ended with Threshold being lost to the other Hollow Worlds. Accounts of that distant time, confused as they are, tell of great catastrophes from attempting to realign the worlds, of tides that drowned cities and suns that darkened for centuries.’

‘If this Orrery is so dangerous, why not destroy it?’ growled Haakan. ‘To leave such an advantage open to the enemy is foolishness.’

‘It has been tried,’ said Cheng. ‘But the Orrery is invulnerable, self-repairing any damage caused to it. We have done all that we can, building the Ironshore around it and creating a complex entry system.’

‘Does anyone else know of this access system?’ asked Pranix.

‘Well, yes, but only the elites of each wor–’ started Cheng, but Pranix cut him off.

‘We can presume then that your security arrangements will already have been compromised,’ said Pranix. ‘Also that the Orrery will be Blackheart’s secondary target, if not his primary one. Great catastrophes, you say? That will be the kind of leverage Huron Blackheart likes.’

‘Then our strategy is clear,’ said Wolf Lord Haakan. ‘We send our fastest forces to strike hard on Hacasta, to intercept the traitors before they can reach Karstveil. Crush their advance then press on, driving them back.’

He brought down his fist on the map where the assault would take place, shaking the table.

‘Let the hammer of Fenris fall,’ snarled the Wolf Lord.

Fourteen

That night, Kretschman woke covered in cold sweat. The room was dark but his eyes saw perfectly – he was in a draughty servant’s room in the governor’s palace on Trincul. They were due to move out in the morning, abandoning Cheng’s ridge runner in favour of Pranix’s forces and Cheng’s moving together to the Ressial Gate.

There was a small sink in the corner of the room, and Kretschman walked over and turned the cold tap on. After some creaks and groans, cleanish-looking water trickled out, and he put his mouth under the tap to drink some.

Afterwards, he wiped his mouth with the back of his hand, and stared at himself in the dirty mirror on the wall. There had been a dream that disturbed him, but he could barely remember the details.

He had been back in the system governor’s war room, but there was only him and Kulbard, discussing the conflict and moving the tokens representing the forces around the maps with long sticks.

Kretschman couldn’t remember the exact words from the dream, but he did recall debating the merits of the inquisitor’s plans, and also that the tokens, instead of being one small representative model for each force, had been hundreds of tiny, living Imperial Guardsmen and Space Marines, protesting as they were swept around the map.

As was often the case with dreams, the logic and sense of place had been fluid, and sometimes Kretschman and Kulbard were looking down at places on a map, and at other times they were in the places themselves, back on the battlements of a ruined Rubicon, or out on the plains of Hacasta where battle would be joined.

Kretschman wasn’t sure whether he was anxious about the battle, or just the fact that when it began he would be on Ressial instead. Was it the prospect of facing the traitors again that disturbed his sleep, or the prospect of not being allowed to?

He shook his head. He wished he were back with his regiment where he belonged, with the simple certainties of a Guardsman’s life. In the meantime, he still needed to sleep, so he returned to the reassuring discomfort of a servant’s cold bed.

His long meditation over, Anto was allowing his slaves to secure him back into his armour and robes when Huron entered the desecrated temple, Terminator guards close behind.

‘Valthex’s monitoring suggests the inquisitor has returned,’ said Huron Blackheart, terrified slaves scattering ahead of him. ‘There has been great activity around the other gate – a number of ships have docked.’

Anto secured his helmet, and a slave passed him his staff. He dismissed his servants with a wave of one gauntleted hand.

‘I know, my lord,’ he said to the Tyrant. ‘He brings with him Space Wolves, and intends to disrupt your invasion.’

‘Dogs of the Emperor,’ snarled Huron. ‘Ferocious, they do not break easily, but they are crude and direct. Across so many worlds, they will be spread too thin, unfocused.’

‘The inquisitor provides them with direction,’ said Anto. ‘He wields them as a blunt weapon against us, aimed with his precision.’

‘Then remove that intelligence,’ said Huron. ‘Do what you should have done before he fled these worlds. Kill that inquisitor for me, and these Space Wolves will be little more than rabid animals to hunt down at our leisure.’

Days passed, and corvids flew between worlds.

At the foot of the Archway between Trincul and Ressial, Lord Inquisitor Pranix set up his maps beneath water-resistant canopies, the rain hammering on the taut material.

He studied reports; he moved pieces on the map.

Lines drew closer together. Armies were on the march.

On Laghast, only a thin army of occupation remained in the ruins of Rubicon, mostly mortals and mutants with a handful of Red Corsairs left to provide leadership. Enough to secure a route of retreat from the front lines of the Corsairs’ incursion to the Hellward Gate, should such a route be needed.

Garreon had departed to lead the strike on the Archway between Kerresh and Hacasta many weeks ago, while most of the rest had moved out with Huron’s galleons in the last few days, their bloodied banners unfurled.

Anto was one of the most senior Corsairs left on an occupied world, and even he had orders to catch up with Huron’s army at the first opportunity. But he had work to complete first, work that required a familiar environment adjusted to his ritual specifications.

In the centre of his desecrated temple, Anto cut his hand and let his own blood run onto the floor, mixing with the blood of sacrifices killed by a ring of mortal followers, whose feverish chanting underscored the incantations of the sorcerer who towered over them.

As his followers let the blood drip from the necks of the innocents they had just killed, Anto allowed himself to savour the irony. While the blood of innocents was vital to the ritual that broke the veil between this reality and the immaterium, the shedding of blood was not the only role each of these subservient mortals had to play.

Each had been drawn from the many treacherous mortals who, seeking favour with their new masters, prostrated themselves before Anto in the streets of Rubicon each day, pleading to be allowed to serve. He had selected each for their profound ignorance, and their ambition. These were men and women with no faith in the Chaos gods, just a desire to obtain some small scrap of great power to advance their own petty ambitions.

They had learned their part in the ritual well, eager to please their master, but none had any idea of the import of what they were saying, and the results of the requests and pleading they were muttering in lost languages they could never understand.

And, as the mortals sacrificed their souls, Anto, their master, stood between them, fluently incanting the punishment to be meted out for their sins.

A sphere of screams began to form in the centre of the room, ice frosting around it and then turning to steam, a great ball of dark energies in which tormented souls could be seen twisted in agony.

Then those energies were released, hitting each of the mortals in turn, causing them to drop the corpses of Lastrati stupid enough to maintain faith in the Emperor while living under Chaos’ rule.

Anto’s followers, those who had taken knives to their own kind to please their new masters, suffered an even worse fate – their skins began to boil and distort, stretching and darkening. Bones cracked and reformed. Recognisable human screams turned into something else: unrecognisable animalistic howls.

Anto performed a brief rite of annulment, sealing the small rift to the warp he had opened. The damage had been done, the process begun. Now he just had to watch the consequences.

The sacks of flesh that had been his mortal acolytes twisted, bat-like wings sprouting from backs, arms and legs extending into clawed limbs with razor-sharp talons. One of these creatures even tried to get to its feet, slashing at Anto.

The sorcerer batted it away with a gesture, laughing at the impudence but admiring the once-human creature’s spirit.

Their forms were settling now, with hideous heads showing heavy brows and wide, fanged mouths. Wings began to flap, and the creatures began to lift off the floor, desperate to brutalise mortal flesh.

Anto slammed his staff against the floor and unleashed a punishing blast of psychic energy, bringing the newborn creatures crashing down to the floor.

‘Not yet, my furies,’ said Anto. ‘Reborn you may be, but you are still bound to my will, and I have a very important task for you to perform…’

Days passed, one after another.

On the throne world of Ressial, a great barge crossed the murky seas between the Archway and the forested continent that was home to the great institutions of the Hollow Worlds. Aboard the barge were most of Inquisitor Pranix’s strike force – Space Wolves, Tallarns and Cadians – as well as Lord Cheng’s retinue.

Kretschman was unsure as to which group he belonged. He was unsure of much, these days. His sleep was further disrupted with dreams and nightmares. He felt he saw Kulbard out of the corner of his eye, soaked in blood.

Anxiety was not a Cadian quality, but the further Kretschman stayed within the safety of Pranix and Cheng’s world, far away from the front lines, the more disturbed he felt. He felt guilty for not being where he could best do his duty when whole worlds were at war.

Perhaps that was where these melodramatic visions of Kulbard came from. The scout was almost certainly dead – there had been no news of him since limited communications were restored with Laghast, not that there was likely to be in the terse reports from the few pockets of rebellion left there. Pranix received reports from the corvids of the Ecclesiarchy, some of which captured picts with the implants in their heads, but most of these were from Hacasta and Kerresh.

Kretschman was aware of the guilt some survivors felt, but had no idea why it might affect him now, and in relation to a scout he barely knew. When had he even met Kulbard in the first place? He could hardly recall now.

From the deck of the barge, Kretschman could see the spires on the shoreline ahead, and knew that in the dark woods beyond lay the Gatehouse. He couldn’t see the Gatehouse itself, but he could see some of the higher towers of the Onyx Palace that dwarfed it, stark against the more muted hues of the mountain range beyond.

Nearby, Pranix was poring over his charts. He had abandoned all the other Hollow Worlds, and now simply consulted maps of Kerresh and Hacasta. Many of the model units had not moved in days, not because their real equivalents were static, but because the information supply was beginning to dry up and Pranix didn’t know where they were.

The corvids came less frequently now, with their reports from the Cadians, Jandarme and Lastrati Guard units still at large on worlds tainted by the Red Corsairs. Pranix had more direct contact with the Space Wolves moving out into the field, as the Fenrisians had fully functional comms protected from Red Corsairs scrapcode by the powerful blessings and wards of their Iron Priests, but the Space Wolves had yet to reach enemy territory and so had little to report beyond their own movements.

While they secured the throne world, they waited for news from the front.

The great, single continent on Hacasta, the one lumpen block of ice-covered dry land on a world characterised mainly by frozen seas where icebergs broke against each other, was a freezing wasteland, a lifeless expanse that few living things could survive, and which required great preparation and resources for human beings to traverse.

To step through the Archway from the damp but entirely habitable marshes of Trincul was to plunge into a world of inhospitable ice, the relentless cold attempting to steal the breath straight out of a person’s lungs.

Throughout the Hollow Worlds, Hacasta was generally regarded as hell.

‘It’s like being home!’ exclaimed Sindri, looking out over the icy wastes as he jumped down from the Rhino.

They had made camp near to the Archway from Trincul, in one of the more bearable parts of Hacasta, where the heat from nearby hot springs allowed some degree of human activity to go on. They were at the edge of a supply station where vehicles were being refuelled, near a frozen lake.

Sindri looked down into its waters longingly.

‘I imagine there are some truly appalling beasts lurking in such dark depths,’ he said. ‘Who wants to lose this power armour and have a swim? I want to strangle some eight-eyed fish that has never seen daylight.’

‘Your valour in the face of monsters that exist in your imagination does you credit,’ said Anvindr, walking out onto the icy ground. ‘But we have bigger beasts to hunt.’

‘Aye, that is certainly true,’ said Sindri.

Traitor Marines. Anvindr himself had found the thought taking him aback occasionally, since they had discovered who had invaded the Hollow Worlds.

It was not that they were afraid – the Sky Warriors only let themselves experience fear around the hearth, telling their accounts – or that they were unaware of the existence of Traitor Marines, simply that they found the blasphemy of Space Marines turning against the Emperor, their leader and the distant genetic ancestor of all their kind, hard to stomach.

Such enemies did not just need to be defeated, or even killed. Their presence needed to be struck out of existence, a blasphemy scoured from the surface of the universe.

Traitor Marines. The thought was repellent, an abomination. Anvindr realised that one of his gauntleted hands was clenched in anger.

He would enjoy killing these traitors, but sadly the privilege of striking Huron’s army head on would be denied to Anvindr and his pack, at least for now. The Space Wolves’ transport capabilities had been devastated by the Alixind Campaign, and there was a shortage of Rhinos and the other hardy vehicles required to cross the wastes and intercept the enemy.

Folkvar’s tanks would travel as the crow flies – an expression exceptionally appropriate, considering the Lastrati’s use of such birds as spies and messengers – to an icy plain between two dagger-like mountain ranges, the battlefield where the Space Wolves would intercept the Corsairs before they reached the Archway to Karstveil.

It was a fast, hasty strike against unknown numbers of enemies in hostile conditions, in which many of them would surely die.

While Folkvar led this strike, the rest of the Space Wolves and Tallarns would travel within the train-like vehicles that ran across the ridges within the Hollow Worlds, to a location near the Archway between Hacasta and Kerresh. From there, they would march towards the Archway, breaking the traitors’ foothold on Hacasta through swift, stealthy attacks, interrupting any supply lines, before launching an attack through the Archway itself and on to Kerresh.

Both assaults were part of the same strategy, both would undermine the enemy, but Anvindr envied those who went with Folkvar, who would do battle against overwhelming odds. That would be a battle to be retold in the sagas.

At some point in the distant past, so it was said, the climate of Hacasta had collapsed, causing great disruption. The planet had been thrown into an endless ice age, but in one small area volcanoes had erupted from the ground. The logic of this was baffling – how could a world without a core have such phenomena? – but the volcanoes existed nonetheless, another example of the Hollow Worlds operating by rules no human could hope to comprehend.

The Ecclesiarchy, as was their perverse tendency, had interpreted the existence of this warm, highly unstable part of the planet as the Emperor’s blessing, and built a series of cathedrals and monasteries in the volcanic region. From these great houses of faith came the preachers and monks who brought righteous terror upon the populations of all the Hollow Worlds. That they trained for holy service in an area where thousands of their kind had been killed by random lava flows in the past was a testament to the strength of their faith.

The holy men produced by the seminaries at the feet of the volcanoes were called the Burning Priests.

Anju Badya and her Rough Riders were told this story as they camped overnight on the blackened volcanic rock, a brief few hours of rest before they were loaded, along with their steeds, upon the tracked transports that would allow them to accompany the Space Wolves tanks in the next part of their trek.

The tale was told by one of their Lastrati guides – most instrumentation seemed to fail altogether on Hacasta, a reason most travel on the planet went via the far longer, but more navigable sea routes rather than across the wastes – and while the cathedrals were mere spires in the distance, Badya had no reason to disbelieve the man’s tale.

The risk of death in a warm climate was at least preferable to the endless chill out in the wastes. The Tallarns had already set out from the encampment a number of times since the strike force came through the Archway to Hacasta, spreading out beyond the volcanic regions to scout for enemy activity.

Badya had taken her turn scouting. She had seen nothing – as their intelligence indicated, the enemy had no presence this far away from their incursion point around the Archway to Kerresh – but the experience had been hazardous nonetheless. Even under layers of protective clothing, the chill had reached to Badya’s bones, which was why she warmed herself so close to the fire now.

The Space Wolves didn’t appear to notice the piercing cold, and many of them seemed more content than she had ever seen them, as much as such restless, aggressive beasts could be said to be content.

Any levity ceased when Folkvar passed. The great master of tanks had become something of a legend during the Alixind Campaign. Old, a Long Fang in the Space Wolves lexicon, Folkvar had crawled out of so many wrecked tanks in his long life he was practically a tank himself, bulky metal limbs augmenting his Terminator armour, his helmet welded into a heavy apparatus that covered his shoulders, the faceplate grilled and shovel-shaped like the front of a Vindicator.

It was Folkvar who led them now. The Tallarns, fleet as they were on their horses, would be a useful distraction while Folkvar’s tanks pounded the enemy. Flanked by Iron Priests, Folkvar clunked around the encampment, barking orders for repairs and maintenance to be conducted. No vehicle would disgrace him when they drove out tomorrow.

And tomorrow the Tallarns and their mounts would go with the Space Wolves, humans and animals crammed together in stinking pens aboard their transports, waiting to be let out onto the frozen plains of the wastes, to strike as hard and fast as they could.

That was tomorrow. For now, Badya and the riders would feed their steeds, watch the fires of the burning mountains and wait for dawn.

From a tower near the Archway that led from Kerresh to Hacasta, Garreon looked out across the Red Corsairs forces building there, at the army of mortal soldiers, slaves and followers they had amassed. A sea of humanity turned to Chaos by his own influence, as well as that of the Red Corsairs’ corrupting presence. Some amongst the throng were already showing the signs of blessed mutation, indicating their commitment to the faith.

Many of them would soon die. Garreon had led the expedition to capture the Archway, including the Hacastan side of the divide, and knew that these mortals, with their crude tattoos of heretical symbols and makeshift weaponry, were not prepared for the harsh environment of Hacasta, for the relentless cold.

To Garreon, the ice winds of Hacasta were merely an inconvenience.

To these mortals, they would be fatal. They had little armour. Their converted vehicles, while augmented with weapons, were not environmentally sealed to keep the weather out. As these mortals drove in the shadow of the galleons, crossing the plains of Hacasta to reach the Archway to Karstveil in optimum time, they would freeze over, their hearts stopping, their bodies left to be buried in snow drifts.

Garreon knew this for a fact. He had conducted extensive tests on mortals and their tolerance to extremes of temperature, and no level of fanaticism or faith could halt the ravages of hypothermia.

Not that he cared. They were mortals; to die for their betters was what they were good for. It provided some purpose to their short lives. He could always round up more from the Hollow Worlds the Corsairs had already conquered.

Garreon acknowledged that a mortal army was a necessity. The Red Corsairs were powerful but few, with newcomers defecting from other warbands only matching the deaths in their ranks.

One Corsair could level a city, given the correct weaponry and opposing even the most well-armed mortals. As a warband, they could raze a planet.

But to conquer a system of worlds, to hold territory and advance beyond it? This required sheer numbers, a growing infrastructure of followers and fellow travellers to solidify the occupation. In other words, mortals.

The stupidity of these mortals, relative to their masters, was also an asset, the haze of wilful ignorance that welled from the intensity of their newly discovered faith. These mortals, who fell to their knees before the lowliest ranking Red Corsair, expected nothing of Huron Blackheart, and had no point of comparison for his current behaviour.

The Red Corsairs had other expectations. Rage and instability were normal for Huron Blackheart, but the periods of seclusion he had recently undertaken were not. The Corpsemaster, along with Valthex and Huron’s innermost circle of sorcerers, had zealously guarded the truth of Huron’s current condition, the instability that threatened to pitch him into mindless daemonhood.

But the Red Corsairs were by nature treacherous, paranoid and ambitious, highly attuned to frailty or uncertainty, even in one so powerful as Huron Blackheart. Those more void-attuned amongst their ranks may even have been able to sniff out this… illness.

All this, while their forces had been spread thin across multiple worlds. Plenty of time away from the eyes of their leader, plenty of time for treachery to fester.

There was danger, here, but opportunity also. While Huron led his army to Karstveil, Garreon would remain behind, and would likely witness any growing tensions in the Tyrant’s absence.

He would need to take the measure of the situation very carefully as the days unfolded, and act with the same surgical precision he applied to his experiments.

Above the massing army of Huron Blackheart, a corvid circled, its implanted, pict-capturing artificial eye looking down on the forces below. It made a wide arc over the massed Corsairs and mortal slaves, the galleons and the tanks, then made to fly back through the Archway to Hacasta.

A sniper’s bullet hit it in the torso, detonating and leaving nothing but a thin spray of blood, scraps of flesh, black feathers and metal filings, most of which were carried away on the winds.

‘One less spy for the lord inquisitor,’ said Wuhrsk, lowering the long-barrelled rifle. He was standing in the centre of Huron’s massed army, and no one, Red Corsair or human, paid any attention to him firing into the air.

‘It could just have been a bird,’ replied Malinko. ‘Although, I would understand if you just didn’t like birds.’ He paused. ‘I don’t like birds.’

‘It wasn’t just a bird,’ said Wuhrsk, detaching the hugely extended barrel. ‘Normal birds don’t fly in the pattern required to assemble a grid of picts covering this entire area.’

Malinko shrugged. ‘I still don’t like birds.’

‘You don’t have to like the birds,’ said Rotaka. ‘Just shoot them when you get the chance. Lord Huron’s orders.’

‘I don’t like them,’ said Malinko. ‘Doesn’t mean I want to waste a shell on them.’

‘Yours is not to question,’ snapped Rotaka. ‘Just to obey.’

Malinko shrugged again.

It was minor insolence, Rotaka knew that, nothing on the scale of treachery for those who had rejected their God-Emperor to embrace Chaos, but these minor incidents were becoming more and more persistent. Not just from loudmouths like Malinko, but among the rank and file of the Red Corsairs. Subtly, authority was being challenged.

This discontent was yet to be crushed. Huron’s forces heeded the call, coming together at the Archway, preparing to move out to Hacasta, yet Huron himself was virtually absent, sequestered within his personal quarters on one of the galleons. In his absence, dissent was growing.

Before, Rotaka would not have hesitated to strike down any dissenter, but now he held back. After what he had seen… He had tried to dismiss it as a brief vision, some side effect of drinking from the Cup of Blessings, but it all fit too well.

He had not mentioned what he had seen to anyone, but still he could see a restlessness amongst the Red Corsairs. Away from the controlled hostility of ship-to-ship raids, and the personal fiefdom of their base within the Eye of Terror, the freedom that they had tasted within the Hollow Worlds, of conquering and dominating mortals, of being gods amongst men… it was intoxicating.

It was home. Rotaka realised he had not felt such freedom since the glory days of Badab, before they were driven out, before they even were the Red Corsairs.

To not be a scavenger, but to rule over worlds.

If Huron Blackheart simply wished to strip the Hollow Worlds of whatever he needed to ensure his recovery, Rotaka did not know how the ranks of the Red Corsairs would react. He did not know how he would react, he who had sacrificed so much already out of loyalty to the once Lufgt Huron.

And so, when Malinko spoke out of turn, Rotaka stayed his hand, and did nothing.

By the time the army of Huron Blackheart rolled out of the Archway onto the surface of Hacasta, Garreon’s raiding parties had already razed the complex that surrounded the Archway.

The Red Corsairs and their mortal slaves had taken hammers and explosives and fire to everything, demolishing every building, crushing it to create a smooth entry ramp for what would emerge from the Archway.

They left a small city reduced to flames dancing across burning rubble, and those in turn were extinguished by the gently falling snow, until all that was left was a white expanse across which Red Corsairs and heavily wrapped human soldiers patrolled back and forth.

These patrols ceased as a dark shape began to emerge from the Archway, half the height of the great arch itself, a galleon of Chaos rolling on huge wheeled tracks. Its darkened bulk creaked and groaned as it pushed between the worlds, a shifting black monolith to contrast with the endless white.

As the galleon rolled out onto the wastes of Hacasta, the master of that galleon watched from the prow as smaller vehicles emerged from the Archway too, swarming around the galleon like greedy fish following a great whale, hoping to feed on any scraps it left behind.

Huron Blackheart looked out across the wastes, his solitary organic eye unblinking, staring out into the relentless cold.

He emerged out of seclusion not to give a speech to his army as they drove out to conquer a new world, nor to give any specific orders. He simply stood silently, observing, as if he could see whatever distant objective he sought, whole worlds away.

One final day passed.

Lord Dumas Cheng felt some sense of personal contentment now that he had returned to the Gatehouse on Ressial with Pranix’s forces at his back. To walk the corridors that so many system governors had before him, to look out from the Gatehouse’s windows to see Space Wolves, Adeptus Astartes no less, marching past.

With these Space Wolves and the inquisitor at his side, surely Ressial would be secure? And from the secure base of Ressial they would take back his Hollow Worlds from the traitors before any even set foot on the throne world. The Hollow Worlds would endure, as they had for so many millennia. Yes, they would.

Cheng found the inquisitor in his war room. Pranix was staring at his charts, but his eyes were unfocused, as if he were looking at something other than the view.

‘Inquisitor Pranix?’ asked Cheng.

‘It’s not enough,’ said Pranix, not looking at Cheng as he spoke.

‘I’m sorry, lord inquisitor?’ asked Cheng. ‘What is insufficient?’

‘Information,’ said Pranix. ‘The supply of intelligence is running dry. I know that the enemy have consolidated their forces – I suspect they’re on the move, but…’

He let the sentence trail off, waving his hand in a jerky, frustrated gesture, as if trying to pull the answer from himself and cast it into the room.

‘The corvids must have been spotted and destroyed,’ said Cheng. ‘It was to be expected. We still have scouts on the ground and other channels, albeit slower ones. Once the Space Wolves have made contact, they will doubtless report back with more accurate intelligence.’

‘That will be too late,’ said Pranix. ‘To know the numbers of the enemy on the verge of conflict gives us no advantage at all, and time is very short.’

‘You believe the battle will be soon?’ asked Cheng.

‘With such fragmentary intelligence it’s hard to make a precise prediction, but I believe our forces will be intersecting with the path of the traitors… now. More or less,’ said Pranix, still staring at the table in front of him.

‘Then these traitors will be driven back. They will die for their insolence in invading this system,’ said Cheng.

‘Of that we can be certain,’ said Pranix.

But for once, to Cheng’s ears at least, the inquisitor didn’t sound certain at all.

Fifteen

Few living species survived for long on the frozen plains of Hacasta, but the Vostroyan iceworm was one of them.

Even in deepest hibernation, an iceworm was always sensitive to vibrations in the ice, to the signs of something moving above. Swiftly, the creature would tunnel up to the surface, ready to burst from beneath the ice and sink its sharpened teeth into vulnerable, warm flesh.

One such worm felt a deep vibration through the icy ground above, and began working its way upwards, wriggling through the packed snow. This prey was large, and approaching at a steady rate. Instinctively, the long iceworm positioned itself in the path of the huge creature and sprang from the ground in one fluid motion, its open mouth striking its target in less than a second.

The iceworm’s teeth shattered as it tried to bite into the wheeled track of a land galleon. Before it could even recoil the great wheel rolled over the creature, crushing it utterly.

As the worm’s thin, purple blood seeped out into the snow, the forces of Huron Blackheart rolled on, remorselessly. Ahead lay a range of sheer mountains, and a narrow corridor through which the land galleons of the Red Corsairs could pass.

Beyond that corridor lay the Valley of Blades.

The Rout were renowned for their capacity to kill with their bare hands, for the immediacy and ferocity they brought to the act of slaughter. For some who had never set foot on Fenris, who knew only of the Space Wolves by reputation, the existence of armoured divisions amongst the Space Wolves was a curiosity, though few would ever be foolish enough to challenge a Space Wolf on how he waged war.

For Garik, driver of Folkvar’s command Land Raider Burning Frost, there was no contradiction, no inconsistency. He had first seen the tanks of the Space Wolves as a Blood Claw, and was enraptured by the sight of the great vehicles manoeuvring with the agility of a hunter, gun turrets swinging around to obliterate their targets. To the young Garik the tanks had been more than machines; they were great beasts themselves, animalistic extensions of their drivers.

To wield a chainsword or axe as an extension of oneself was difficult, but easy to imagine. To come together with others of your pack to control a great machine like a Vindicator tank with the same organic fluidity, to let the warrior spirit flow as naturally through complex controls, was a different order of challenge.

Greater still was the challenge undertaken by Garik’s commander, Folkvar, to make not just Burning Frost but all the tanks under his command an extension of his will, to lead the vehicles as a pack.

Folkvar commanded the greatest of respect. So when he chose to speak, the Space Wolves under his command listened. Garik and the ten Space Wolves crammed into the Land Raider’s hold were rapt as Folkvar spoke in his grating, metallic voice.

‘We do not command these machines,’ Folkvar said. ‘We are our armour, part of the machine.’ From his command throne he rapped a knuckle against the metal of Burning Frost. ‘The iron guards the Space Wolves within, Frost and Space Wolves together become guardians of the Imperium, of the Emperor’s will, armour made not just from welded metal but from the spirit of the Space Wolves within.’

It was a lesson Garik had heard many times before, but never tired of. Having risen through the ranks, Folkvar had hammered those who served under him into his own image, brooking no failure. Every tank beneath Folkvar’s command was of a type he had once commanded himself, from the nimble Whirlwinds to brutish Vindicators.

Now he had the honour of commanding Burning Frost, a monstrous Land Raider with centuries of service to his pack, and Garik had the honour of being Frost’s driver. In preparation for facing the Red Corsairs the Iron Priest had made offerings of flesh to the Frost’s machine-spirit and Garik could feel the tank’s hunger for battle, an aggressive presence pushing at the back of his mind.

‘We wait,’ said Folkvar, clearly feeling it too.

The tank had been still for a while, and looking back from the driver’s seat, Garik could see an exchange of glances between the Space Wolves in the hold questioning why Folkvar had spoken. Only Garik truly understood that Folkvar addressed the machine-spirit of Burning Frost itself.

Folkvar pressed a rune and spoke into the vox: ‘Whirlwinds, report.’

They would confront the Red Corsairs at the entrance to the Valley of Blades, a wide-open plain between two ranges of frosty hills covered in spiked ice formations. Those peaks were not entirely impassable, and the four Whirlwind tanks under Folkvar’s command had been deployed to take firing positions overlooking the plains.

‘Approaching position,’ voxed Ake, commander of the Whirlwind White Squall, and Garik could hear him speaking through gritted fangs as the Whirlwind painstakingly worked its way up a narrow mountain path. Atgeir, Tempest and Laniger were already in position, and voxed in to say so.

The Burning Frost, and the other heavy tanks Frozen Blade and Ice Storm were out of sight at the foot of the hills, rolled behind drifts of long-frozen, ancient snow. The four Vindicators, with their short firing range, had been covered with fresh snow and positioned closer to the more easily navigable part of the valley, so that they might get in range quicker. Folkvar had half a dozen Rhinos and a Tallarn company of sixty Rough Riders under his command, all of which had dug themselves in, ready to ambush the Red Corsairs.

The other commanders reported in. All were moving into position.

None of them knew exactly the force they were about to face, having only received blurred picts of large, ship-like vehicles and the accompanying tanks and carriers, but the plan was to ambush the first vehicles to enter the valley from a narrow pass at one end.

‘Whirlwinds, fire on sight,’ Folkvar ordered over the vox.

Bringing down the first vehicles in the convoy would create an obstruction and confusion in the enemy ranks. With the convoy bottlenecked at one end of the valley, the Vindicators and other tanks would move in to strike hard and close, driving back the Red Corsairs and causing a rout. The Tallarn Rough Riders would be set loose to bring down any smaller targets, to help hold the line.

Garik liked this plan. It was simple, an onslaught of measured aggression to rain destruction on the enemy in a swift but lethal strike.

All that remained was to wait for the enemy to arrive.

In the command chair of the Burning Frost, Folkvar waited, a man of iron at one with the iron around him.

Tothsen, shipmaster of the Red Corsairs galleon Implacable Stalker, was a once-human creature riddled with cancerous growths, some of which had their own mouths. As he stood on the bridge of the Stalker, looking over the busy deck to the mountain walls the galleon was passing between, Tothsen was restless. The convoy of vehicles had slowed considerably once they entered the pass between the mountains, the mutated crews of the galleons constantly struggling with the minute course adjustments required to avoid collision with the sheer walls of icy rock on either side, walls that towered over even the land galleons. Behind the Stalker in the convoy was Huron Blackheart’s personal galleon, his flagship, the Unyielding Fist, and Tothsen could imagine the boundless rage the Tyrant would have if he considered the Stalker to be delaying his own progress.

He kept his primary mouth shut, but the other mouths on Tothsen’s body were treacherously whispering terrible oaths in an unknown tongue.

‘It goes on forever,’ said Tothsen’s comms officer, Skartz.

Tothsen looked askance at Skartz, whose purple, crab-like head looked like it would crack easily with a solid enough blow. Sometimes Tothsen was tempted to try it.

‘If only it did, Master Skartz,’ said Tothsen, his words summoning a laconic courage his other mouths lacked. ‘Soon we will get to the Valley of Blades.’

‘Yes, shipmaster,’ said Skartz, but his tiny black eyes showed little understanding.

Then the dogs will fall upon us, thought Tothsen.

As he looked out for the entrance to the Valley of Blades ahead, Tothsen kept one hand on the newly installed rune in front of him, and hoped that this latest creation of Lord Valthex would buy them the fighting chance they needed.

‘Great Russ,’ said Gosta, driver of the Whirlwind tank White Squall, wrestling with the control runes to stabilise the tank. ‘It would have been easier to climb on foot and pull the Squall up with a rope.’

‘You have kept to narrower terrain than this,’ said Ake, the tank’s commander. ‘Remember the trenches of Bendeev? We reached the enemy lines without a scratch from those close walls.’

‘Aye,’ replied Gosta. ‘But an error there meant damaged paintwork, not a drop into a ravine.’

Looking through the narrow slit, Gosta could make out the white expanse of the valley to his left, the white expanse of the ice wall to his right and the thin trail of white that was the path he was driving up ahead. He was of Fenris; he had no fear of snow or ice, but damn did it make navigation difficult.

Eventually, they found a firing position overlooking the valley. Gosta climbed out to pack snow around the Squall to conceal it while the missile launcher was adjusted to aim at the entrance to the mountain pass below.

It was from there that Gosta saw the first enemy ship emerge.

The scattered reports from survivors that had filtered back to the Space Wolves had called these vehicles galleons, and even though they rolled on giant wheeled tracks on land, that was still an accurate description. The nose of the vehicle that emerged could only be described as the prow, a sharp, high-sided hulk of dark, oily, rusted metal that seemed to cut into the white of the valley below. Gosta could see movement on the deck, and knew that those specks were mortals, which only emphasised the hideous scale of the galleon.

‘Fire,’ shouted Ake, and the Squall unleashed its ‘teeth’, powerful frag missiles that cut through the thin, freezing air between the Squall and the galleon.

From his command throne on the Frost, Folkvar watched on his auspex as the frag missiles from the Squall streaked towards the galleon, along with missiles from the three other Whirlwinds planted on high vantage points. There followed a huge explosion, the impact of which was felt through the ground across the entire valley, as smoke billowed out in all directions, temporarily obscuring any view. The noise of the explosion echoed back and forth, causing avalanches and shattering many of the icy blades that gave the valley its name. The vidscreen went white with smoke and powdered snow.

As the noise receded and the vibration ceased, the traitorous hulk emerged from the smoke, rolling completely on to the floor of the valley and free from the mountain pass. It seemed to be unharmed.

‘We’re still alive,’ said Skartz, without any particular emphasis.

‘We are for now,’ said Tothsen. His hand was still pressed down on the rune for Valthex’s device. ‘Inform the Unyielding Fist that the fireburst worked.’

‘Aye, shipmaster,’ said Skartz, who started relaying the message via the vox.

The fireburst was a one-shot missile disruption system rigged on the deck of the Stalker, installed on the orders of Valthex on the presumption that the Stalker would come under immediate missile attack when it entered the valley. When activated it had launched bursts of red-hot debris from several launchers on the deck, causing the missiles to explode before hitting the galleon. An ingenious device, but one that could only be used once.

It would also have been for nought if Tothsen’s crew couldn’t take out the tanks that fired those missiles.

‘Gun batteries to port,’ Tothsen shouted. Outside the armoured confines of the bridge, Tothsen could see the crew on deck dodging fragments of burning matter still falling from the sky after the disrupted missile attack. ‘I want that cannon moving too. Pilot, bring us hard to starboard, but don’t lose forward momentum. The sooner we cut the Fist loose the better.’

Gosta was back at the White Squall’s controls when the las-fire started melting the snow all around the tank.

‘Reverse as far as we can,’ shouted Ake over the noise.

Gosta didn’t answer; he was too busy enacting the order. Whirlwinds were relatively nimble on the worst terrain, but the gears still ground as Gosta threw the tracks into reverse and started rolling backwards from the edge. As the Squall reversed it was out of direct line of sight to the galleon’s deck, and the las-fire, but through the viewing slit Gosta could see las-fire tearing into the mountain side, dislodging chunks of ice and rock that rattled down on top of the tank.

‘Are we ready to fire yet?’ Ake snapped.

‘Almost ready,’ came a voice from up top.

‘All Space Wolves and Tallarn attack,’ ordered Folkvar. ‘I want that galleon taken down.’

The moment of surprise was gone. The galleon would be targeting the Whirlwinds that attacked it, and if the galleon slid into the valley altogether then Russ knew what horrors would be free to emerge from the mountain pass.

Garik slammed the acceleration rune and Burning Frost was one of the first tanks to break cover, packed snow falling off the great Land Raider as it rolled out into the valley. From his command throne Folkvar controlled the Godhammer-pattern lascannons, and targeted the galleon. He cursed that he was not yet in range to use them.

Either side of the Frost, Folkvar could see the smaller, faster Vindicators and the Tallarn Rough Riders edging ahead. Around the valley the Space Wolves and Tallarns were converging on the enemy.

Folkvar hoped they would be in time.

‘We have a target,’ came the shout across the bridge of the Stalker.

‘Then don’t wait – fire,’ ordered Tothsen. From the bridge he could see the huge cannon pointing to port.

While the fragmentation missiles had flown overhead in a graceful arc, the monstrous gun of the Stalker had no such grace or subtlety. It aimed in a straight line, and when it fired it recoiled down tracks on the deck of the Stalker, crushing many of the slaves who had dragged it into place and whipping those who still held its chains off their feet. Tothsen watched impassively as one unfortunate was snapped in half by the whiplash of one chain, while another was flicked off the side of the deck, falling to his death on the icy ground below.

The kickback shook the Stalker and smoke bloomed across the deck, but the shell was launched.

For a brief moment, Gosta thought he wasn’t going to die.

It was less than a second. As he slammed the White Squall into reverse, a giant shell, almost half the size of the Squall itself, cut through the air in front of the tank, and missed.

Then it hit the mountain wall near to the Squall and exploded, tearing into snow, stone and tank alike. The blast ripped the Squall to pieces, and Gosta, Ake and the crew of the Whirlwind were killed instantly, their flesh and armour reduced to incinerated fragments as an explosion became an avalanche, debris tumbling down into the valley below.

Sergeant Anju Badya had felt elation as she rode out across the Valley of Blades.

Between the goggles that protected her eyes from the bitter winds, and the scarves wrapped around her mouth and nose, very little of her skin was exposed to the elements, but the area around her goggles began to smart from the searing cold.

It hurt, but she didn’t care. She was a Tallarn rider, and this was what she lived for, to ride into battle amongst the rest of her company, dozens of men, women and horses sweeping across the valley.

Her horse bucked recklessly, giddy with freedom, but Badya pulled on the reins sharply, bringing it into line. Around her, her squad were similarly settling their mounts.

Anju’s high spirits were shattered as the enemy galleon fired on a high spot up on one side of the valley, reducing a Space Wolves tank to fragments and causing a collapse in the packed snow up the valley’s side.

‘Avalanche!’ she shouted as the reverberations echoed across the valley, but the warning shouted down the line was too late for Tallarns riding close to the edge of the valley, who were consumed by a torrent of snow.

It was a horrible way to die, powdered snow flowing around rider and steed alike, sealing them in while rushing into nostrils and mouths to asphyxiate them, but there was nothing Anju could do. The surviving riders had a bigger problem.

The galleon was such a simple shape, a blocky hulk of toxic looking dark metal against the constant white around it, that it was hard to get a sense of its size until it began to loom over them.

‘Laniger preparing to fire,’ snapped a voice over the vox. ‘Don’t get too close.’

Once more, missiles streaked across the sky, launched from one of the high-placed Whirlwind tanks. Anju and the others circled their horses as the missiles hit the deck of the galleon. She recognised the shape of them – dragonracers, loaded with poisonous, flaming liquid.

This time there were no diversions for Tothsen to use. He recoiled from the viewing slits of the Stalker’s armoured bridge as the missiles hit the deck, unleashing a payload of fire that obliterated every living thing out there. Splashes of burning, toxic gloop shot through the viewing slits into the bridge area, catching Tothsen on one arm, causing him to scream and roll on the deck of the bridge, putting out the fire. While he managed to bind the wound tight enough to extinguish the flame, he could feel the corroding liquid eating into his flesh.

Others had it worse. The pilot was dead, corpse burning, while Skartz was wailing incoherently, his face covered in the poisonous muck. A choking vapour filled the air, and Tothsen covered his primary mouth with his good hand.

Through his delirium, he realised the Stalker had stopped.

Looking out of the viewing slit, he could see that the deck was entirely ablaze. Nothing would be fired from there, and deep gashes had been blown out of the deck itself, allowing flaming liquid to seep into the lower decks. Further still Tothsen could see black dots against the white of the valley converging on the stricken galleon, ready to finish it off.

They would succeed, he was sure. The Stalker was almost dead, but Tothsen would not allow it to go down just yet.

He scrambled across to Skartz’s station. The poison had done its work and the officer was dead. Tothsen pushed his corpse away and hit a vox rune.

‘Engine room, all power to engines,’ Tothsen snapped into one channel, then hit another rune to communicate with the entire crew. ‘Enemy incoming, open all gunports. Fire at will.’

Then Tothsen ran to the pilot’s station, lame arm hanging to one side, and took the station himself. He was the last one alive on the bridge, and he would pilot the Stalker in its vital final moments.

Anju’s horse reared in terror as they approached the galleon, and she whispered soothing words to it. As fellow Tallarn riders threw grenades into the wheels of the galleon to try to halt it, and missiles from the Whirlwinds tore into the higher sections of the ship’s hull, the sturdy Tallarn horses, veterans themselves of countless battlefields, did not flinch, but they recoiled at approaching the galleon too closely.

‘They’re spooked,’ Ejad called to Anju over the roar of battle. He was one of the youngest riders in her squad. A fine rider and a good fighter, he was raw but had good instincts. ‘There’s something of the ghoul about this thing.’

Ghouls were a Tallarn myth, horrors of the desert, and there was something similarly monstrous and unnerving about the galleon, the way its blackness seemed to drink in light.

‘Gunners!’ someone shouted, and Anju looked up to see hatches open in the hull of the galleon and las-fire spit down on the riders below.

Squeezing her horse with her knees, Anju took her hands off the reins and lifted her lasrifle, raising it at a high angle. Compensating for the rhythm of her mount, she closed one eye and looked down the barrel, finding a ragged figure leaning out of a hatch.

She fired, and the figure tumbled out of the hatch, a barely human shape landing lifelessly in the snow.

The riders alongside her cheered as they found similar targets. They would bring this beast low one crew member at a time if necessary, and show that these great machines were no match for the furies of the desert.

‘Move in and finish that abomination off,’ ordered Folkvar from his command throne. Somehow, the galleon was still crawling on, though its deck was ablaze and the fiery liquid from the dragonracers was streaking down its hull. The other surviving Whirlwinds were firing too, missiles pounding into the galleon lower down, tearing into its hull and causing fragments of smouldering metal to rain down from its side.

Yet still it refused to die, and it had almost extracted itself from the mountain pass.

Folkvar himself controlled the Frost’s Godhammer-pattern lascannons, which pumped bursts of las-fire into the side of the galleon. The Tallarns were also moving in, but it would take a more brutal and direct approach to take down the galleon.

‘Tooth, Claw,’ Folkvar ordered. ‘Break those tracks.’

‘With pleasure,’ snarled Eluf, commander of Broken Claw, and the tank roared forwards.

Eluf didn’t need to check the auspex to know that close by Shattered Tooth was doing the same. Within the company these two tanks were known as ‘the twins’. Built in distant times, Shattered Tooth and Broken Claw were Vindicators, stubby, slow vehicles compared to the looming power of a Land Raider or the mobility of a Whirlwind, but equipped with a front-mounted demolisher cannon capable of dealing incredible damage to even the strongest armour. Deployed together in countless battles, their crews came from the same intake of new brothers, and often from the same Fenrisian tribes. Separate vehicles, separate crews, they nonetheless acted with one mind.

As the dark monstrosity ahead rolled further into the open valley, Tooth and Claw converged on it from different directions.

‘Ugly beast, isn’t it?’ said Hagen, Shattered Tooth’s commander, over the vox.

‘We’ve hunted worse,’ replied Eluf with a confidence he didn’t entirely feel as the Claw moved towards the enemy ship. The shadow of its hulk was a spreading patch of darkness seeping towards the approaching Claw. From hatches in its hull, las-fire rained down on the tanks.

‘A beast with fleas,’ said Hagen. Eluf just grunted.

Las-fire bounded off Broken Claw’s armoured exterior. More serious was a rocket that chewed up the ground before Shattered Tooth, forcing Hagen and his men to take evasive manoeuvres.

‘Looks like it’s up to us, brother,’ Eluf said over the vox, to cheers within the Claw. It was Hagen’s turn to express his displeasure.

Broken Claw had a clear path, moving alongside the giant enemy vehicle. As Broken Claw levelled with it, Eluf could see wheels and tracks taller than the tank itself.

‘Stay close, aim for that wheel,’ Eluf ordered. ‘That should slow them down. Fire!’

The demolisher cannon fired once. The Space Wolves shell smashed into the track of the galleon, but exploded in the narrow space underneath the huge ship. While the galleon shook, and Eluf could see that it had suffered hull damage, its progress was not halted and it continued to roll on.

‘Damn this thing,’ snarled Eluf. ‘Prepare to fire again.’

Broken Claw did not get the chance to take another shot. While the front of the tank was heavily protected by a siege shield that locked around the barrel of the demolisher cannon, the armour on the top of the vehicle was less resistant. The severe angle from which the crew of the galleon looked down upon the ground below afforded an excellent view of Broken Claw’s relatively vulnerable roof.

Screaming foul oaths in a heretical tongue, a ragged figure threw itself from a hatch above, landing on the roof of the Claw with a thump. Whether the figure survived the fall was moot, as the explosives strapped to its body detonated, tearing through the roof and into the cabin.

As he and his crew died, Eluf cursed this hellish ship and swore for the Tooth to avenge them.

Broken Claw, a tank that had fought in countless battles over the long centuries, was reduced to a blackened, smoking shell.

Anju rode around the smoking wreckage of the Space Wolves tank, a foul burning stench seeping through the scarf over her mouth and causing her eyes to water. Even the sudden burst of heat in the cold valley was unwelcome in these circumstances.

‘This thing just won’t die,’ shouted Ejad in frustration.

The moribund galleon was still rolling, slow but persistent. It was aflame, smoke pouring out of every firing slit, porthole and hatch on its hull, its armour cracked… and yet it rolled on. The crew fired down on the Tallarns and tanks riding alongside the galleon even as missiles and las-fire tore further rents in its structure.

In Burning Frost, Folkvar cursed. The Godhammers were overheated and needed to cool down. The enemy galleon was nearly out of the mountain pass. The immediate rout he had hoped for, driving the enemy back, was not to be. Soon the other galleons would roll out into the Valley of Blades, and he had lost two tanks already.

Victory would still be possible, but a long painful battle lay ahead.

‘The galleon is out into the valley,’ said Garik.

Folkvar leaned forwards to see what followed it. Even on his viewscreen, the visuals were cloudy with the smoke coming from the slowing galleon in the valley, and it was hard to see what followed. It took a short while for him to realise that there was nothing there.

Even as that first galleon rolled free of the mountain pass, leaving plentiful space for another to follow, nothing came.

As the Implacable Stalker continued across the Valley of Blades, suffering constant bombardment, the Unyielding Fist held back.

On the deck of the Fist, Huron Blackheart looked down from his prow to the mountain pass ahead of him. The Valley of Blades was out of sight to him so far, around a curve in the pass.

‘My lord,’ said Garreon, approaching. ‘The Stalker has entered the valley. The shipmaster believes they will not survive long out there. Shall the Fist follow?’

‘Shall I proceed, Lord Huron?’ asked Valthex, finger hovering on a rune on his auspex.

‘Wait, both of you,’ replied Blackheart. ‘We will take this Valley of Blades soon enough. Let us not squander another galleon to do so.’

Huron walked to the prow, leaning over to look at the amassed forces below, revving engines as they awaited orders: Rhinos, bikers, mutated mortal soldiers on ramshackle vehicles with weapons bolted to the frames, and three red-painted Predator tanks.

He spoke into his vox-bead, addressing the massed vehicles in the shadow of the Fist.

‘Take the valley for me,’ he said to the massed riders. ‘Bring me the heads of these Space Wolves.’

There was a roar from below, both from voices and engines, the two noises mingling into one as the forces of Huron Blackheart drove out to engage their enemies.

Sixteen

‘You will be my eyes in that valley,’ Huron Blackheart had said, addressing Rotaka and his squad on the deck of the Unyielding Fist. ‘For each blow to fall as it should requires you to see clearly. Do not think I will hesitate to pluck out an eye that offends me.’

Huron’s words echoed in Rotaka’s minds as his squad rode out of the mountain pass on their bikes. To be handed such responsibility gave Rotaka a feeling of pride, to have his master put faith in him.

The bikes they rode were powerful, robust vehicles, engines roaring and spiked wheels churning the snow as they shot ahead of the Rhinos, tanks and other vehicles.

‘Beautiful!’ enthused Malinko over the vox as they rode out into a wide valley surrounded by tall, icy mountains. It was not the scenery that attracted Malinko’s attention, but the carnage. The Implacable Stalker struggled on like a wounded animal, bleeding fire and smoke, a blackened carcass somehow managing to keep staggering forwards, while enemies bombarded it from all sides. Great grey Land Raiders and nimble Vindicators encircled the collapsing galleon, while riders on horseback exchanged fire with the crew of the Stalker.

‘Rotaka, report,’ hissed Garreon’s voice in Rotaka’s ear, reminding him that while his squad had been cut loose on the battlefield, they were being kept on a very short leash.

‘The Stalker still functions,’ Rotaka replied. ‘Though not for long.’

‘You have your orders,’ said Garreon. ‘Follow them as Lord Huron expects, and keep me informed.’

Rotaka suppressed the urge to tell the Corpsemaster exactly how little he needed his counsel, and surveyed the battlefield.

‘Let’s cause a little mayhem,’ he voxed his squad. ‘Target the mortals, but keep a distance from the tanks. Evasive swerve once their fire is drawn – let’s pull the big guns back towards the pass, then hand them off to the Predators.’

‘Targeting now,’ said Wuhrsk, spinning around and loosing a volley of bolts towards the nearest riders.

Badya felt the impact as the bolt slammed into her horse’s body, and felt it doubly so when the bolt exploded, burning her leg.

The horse bucked and jolted, almost throwing her off. Agony shot through her leg – her calf was scorched, and the horse’s blood was gushing out of its side.

Anju glanced across to see five terrifying apparitions sweeping across the Valley of Blades, bulky armoured figures on two-wheeled vehicles firing at the Tallarns.

‘Bikers incoming,’ she shouted over the vox. ‘Bikers inco–’

Then there was another burst of fire and a bolt exploded in her horse’s neck; then horse and rider alike were tumbling into the cold snow, and Anju lost consciousness.

‘Garik, get me close to those bikers,’ said Folkvar, before pressing a vox rune. ‘Shattered Tooth, Curved Fang, with me. Tallarns withdraw – the Rout will deal with this.’

Ahead, the bikers were swerving and weaving, unleashing bursts of fire on the Tallarns, who were having difficulty getting a bead on the fast moving bikes.

Folkvar didn’t need a clear shot; the Frost’s Godhammer lasers could strafe a wide swathe and scorch the bikers and anything between them.

‘Moving into range,’ reported Garik.

The Vindicators Shattered Tooth and Curved Fang were matching the Frost’s speed on either side of the Land Raider. Folkvar hit the vox. ‘Tooth, Fang, spread out and drive them inwards. These bikers are mine.’

The heavy shell that exploded near Malinko nearly flipped his bike altogether, the explosion throwing dirt and snow into the air, leaving a wide smoking crater. The pressure of the blast caught the tail of his bike, spinning him around in the snow.

He let out a huge laugh. ‘Which of these dogs wants to play?’ he shouted.

Then he saw them. A Land Raider and two Vindicators, converging on the wide area in which the Corsairs were looping as they fired on the mortal riders.

‘Huh,’ said Malinko. ‘Big dogs.’

‘Shut up, Malinko,’ snapped Rotaka over the vox. ‘We have a bite. Get close to the valley walls and head back. Garreon, are you listening to this? We’re coming in hot.’

‘The others should intercept you at the valley mouth,’ said Garreon.

Malinko got his bike under control and followed Rotaka’s instructions. The others were a little ahead of him, pulling back as one of the Vindicators fired a shell into their path.

‘Damn it,’ snapped Rotaka. ‘This was a bad idea.’

‘I’ll be sure to relay your feedback to Lord Huron,’ whispered Garreon.

Bursts of heavy laser fire began to scorch the snow to mist behind Rotaka and his squad. Between the Vindicators and the Land Raider, they were being driven back, away from their destination.

‘Verbin, think you can knock the Vindicator to our right off course?’ Rotaka asked.

‘Or die trying,’ said Verbin, gunning his bike and racing ahead of the others, heading straight for one of the Vindicators, hauling the plasma cannon off his back as he did so.

‘That’s suicide!’ said Malinko. ‘Why didn’t you ask me?’

As the Vindicator’s demolisher cannon fired, Verbin threw himself sideways and off the bike, which fell on its side and skidded right under the demolisher shell. Landing on his side, Verbin was clear of the Vindicator as it rolled past, firing at the bottom of its tracks and causing it to veer out of control.

‘That’s our gap,’ said Rotaka. ‘Verbin, stay alive and we’ll pick you up.’

The four remaining bikers shot past the Vindicator as it tried to course correct, heading straight for the mountain pass. Malinko looked enviously at where Verbin had rolled to a halt in the snow. He got all the fun.

‘You took your time,’ Rotaka said over the vox and Malinko looked ahead to see Red Corsairs tanks, Rhinos and dozens of smaller vehicles manned by mortals pouring out into the valley.

Narrowly avoiding a collision with Curved Fang, Burning Frost turned to pursue the bikers. From his command throne, Folkvar saw the mass of vehicles emerging from the mountain pass. He saw at least two Predators and three Rhinos driving out, along with smaller vehicles that looked like they were bound together with tape and dirt.

‘Traitors incoming,’ he voxed to the other tanks. ‘Space Wolves, concentrate fire on those Predators. Tallarns, take out the mortals.’

Badya was trapped. Her steed had been gunned down, and she had briefly lost consciousness. Now she was awake and could barely move. Her horse was dying, bleeding out, eyes glazed, breath rapid and ragged.

Worse than the death of a mount she had come to feel was part of herself, Badya was pinned underneath it, the horse lying across her legs and waist. She could feel its hot blood soaking her trousers, and a gradual numbing within her legs. Her body was pushed down into the snow and she could feel the cold seeping in through her protective clothing. If she did not get out soon she would go into shock.

Anju tried to lift the almost-dead weight off her, but she couldn’t – the horse was just too heavy.

‘Sergeant,’ said a voice nearby, barely audible over the din of explosions and gunfire. From her position, trapped on the ground, Badya had very little idea what was going on in the valley now, but it didn’t sound good. She looked up, vision swimming after the blow she had received to her head, and saw a familiar silhouette looking down at her.

‘Sergeant,’ repeated Ejad. ‘Do you need assistance?’

Badya should have said yes, but with the caveat that he should only dismount if it was safe to do so, and if he was not needed, that he should fight the battle they came to fight rather than attempting a risky battlefield rescue. She should have said all of these things, but with the numbness in her legs giving way to excruciating pain, and her vision still blurry and head ringing, she found herself just nodding.

Later, she would reflect that she had given Ejad bad advice. It was her foolish, nodded request that he dismount and help that got him killed. It happened in seconds, a roar of approaching engines, and a hail of gunfire that tore into the bodies of both Ejad and his horse, bringing the animal to its knees.

The wounded rider and horse lurched groundwards, threatening to collapse on top of her, and she had a brief glimpse of Ejad’s mouth open in shock, pale face splattered with his own blood.

Then the engine roar built to a brief, shattering crescendo as something rode past at terrifying speed, a thing of wheels and armour and spikes and skulls. An arm swept past wielding a roaring chainblade that cut straight through Ejad, and the top half of his body was flung out of her field of vision. Badya was still trapped, but now with two dying horses on top of her rather than just one.

Rotaka sheathed his chainsword as the bike roared out across a valley consumed with battle. With the Predators and mortals at their back, Rotaka’s squad could cut loose. The enemy’s attention was divided.

The Tallarn rider hadn’t even seen Rotaka before the bike’s guns shot him down and Rotaka’s chainsword finished the job. It was unlike an Imperial Guardsman to be so conspicuously vulnerable, and Rotaka could only credit this to Lord Huron’s plan, to hold fast until his ploy had drawn the enemy close and sent them spiralling into confusion.

The Red Corsairs had the advantage, but driving across the battlefield with his squad, their bike guns releasing bursts of gunfire to take down riders and foot-soldiers, Rotaka could see that there was still much to be done.

Space Wolves, the Emperor’s rabid executioners. Rotaka had never fought them before, but he’d heard the tales, and knew that, for all their apparent savagery, the Vlka Fenryka should never be underestimated.

The Space Wolves were regrouping now, their tanks attempting to encircle the Predators as they rolled out into the valley. Rotaka could see a Land Raider simultaneously firing on the Corsairs tank Limitless Hatred with its main lascannons, while smaller guns struck out against the mortal vehicles.

‘What now?’ asked Verbin, whose bike had survived the earlier tumble.

Rotaka was about to answer when the vox squawked in his ear.

‘How goes the Stalker?’ hissed Garreon.

Rotaka realised that in the confusion he had lost track of the galleon. He looked across to see it had stopped halfway through the valley, a smoking wreck. ‘It’s stalled,’ he said. ‘No signs of life.’

‘Then draw the enemy close to it,’ said Garreon.

Tothsen had given in to the fumes filling the bridge of the Implacable Stalker, and would have died on the floor if vox-speakers had not started making noise.

The voice that emerged from the speakers made Tothsen’s eyes snap open in panic. It was the voice of the Corpsemaster.

‘This is the Unyielding Fist,’ said Garreon’s aloof, cruel voice over the vox. ‘Implacable Stalker, know that you sacrifice yourself for Lord Huron, in service to his greater victory.’

There was no concern in the demigod’s voice for the plight of the Implacable Stalker and its crew, and Tothsen knew this was right and true. They lived only to serve. He forced himself up to his knees, head bowed even though Garreon could not see him, supplicating himself.

On board the Shattered Tooth, Hagen and his crew had felt the death of Broken Claw, a great grief and colossal rage echoing through the machine itself, and that rage had infected them all with a fearsome bloodlust. On Folkvar’s order the Tooth had engaged one of the Corsairs Predator tanks, only to find themselves pursued by an enemy Rhino.

Hagen would not let this new pursuer stop him taking out his pain over Broken Claw’s demise on one of the enemy Predators. Through the tracks of the tank he could feel the slipperiness of the snow, the manoeuvrability it would allow.

‘On my mark, brake and turn away,’ ordered Hagen. ‘Now.’

Shattered Tooth steered sharply to the left, and Hagen felt his considerable mass swinging violently. For a second it felt as if the Tooth would turn over altogether, but it stayed level, spinning around to face its pursuer.

‘Forward and ram!’ yelled Hagen, and as the more manoeuvrable Rhino swerved around to fire on Shattered Tooth, the Vindicator charged it. The Rhino fired its melta gun, but the siege shield at the front of the tank was strong enough to withstand the assault. The Tooth was nearly upon the Rhino.

At the last second, a smaller vehicle – a slave-driven halftrack with crude armoured sides – attempted to insert itself between its masters’ Rhino and the Space Wolves tank, but such an attempt at defence was useless. Shattered Tooth scooped up the mortal vehicle as if it were a toy, ramming it into the Rhino and causing both enemy vehicles to roll over in a tumble of twisted metal.

‘Find me a bigger target,’ snapped Hagen. ‘Then get me in close.’

‘Pursuing,’ said Onora, the Tooth’s driver. ‘They seem to be retreating into the shadow of the galleon.’

‘Then let’s show them how much good that shelter will do them.’

‘Something is wrong,’ said Folkvar. The kill urge rose strong in him, flowing through his crew and the Burning Frost as if their spirits were one, and it was hard for him to identify the feeling at first. Burning Frost was in pursuit of one of the enemy Predators, which had engaged the Frost then withdrawn. The two tanks had circled each other briefly, shots going wide, and then the enemy was in flight and the Frost followed.

‘Witchcraft, it taints everything,’ spat Garik. ‘These heretics cannot even fight straight without collapsing into disorder.’

‘No,’ said Folkvar. ‘It is more than that.’

The Godhammers spat las-fire as a halftrack loaded with mutated mortals crossed their path, the foul beings opening fire with handweapons. These petty assaults were useless against the Frost’s armour, and the Godhammers chewed their vehicle to pieces, reducing it to molten metal and burning fragments to be pressed into the snow by the Land Raider’s tracks. The intervention had done nothing but delay the Frost, the mortals sacrificing themselves for a few seconds’ advantage, which the enemy Predator had used to swerve close to the smoking wreck of the Red Corsairs galleon. Frustration was building in Folkvar – the Space Wolves cut through the mortals easily enough, but the vehicles of the Red Corsairs themselves, the Rhinos and Predators, proved more elusive.

That feeling, that unease, rose in Folkvar’s throat like bile, bringing realisation. This was not disorder – it was strategy. The mortals were being thrown around the valley like disposable pawns, while the Predators… they were bait. Bait that was drawing them closer to the wrecked galleon.

‘Pull back,’ Folkvar barked into the vox. Garik, sensitive to his commander’s instincts, was already reversing.

‘Now,’ said Rotaka in Garreon’s ear. ‘It has to be now.’

‘My lord,’ said Garreon, nodding to Huron Blackheart on the deck of the Unyielding Fist, which had swept through the last section of the mountain pass at a speed the Implacable Stalker, damaged in an earlier conflict, had not been able to attain.

Now Huron Blackheart stood at the prow of his personal galleon, looking out across the Valley of Blades. The scene was one of carnage – tanks, Rhinos and other vehicles swarming around the ruin of the Stalker, while from the edge of the valley the Space Wolves Whirlwinds continued to fire missiles down into the valley below.

‘Valthex, do it now,’ said Huron.

‘My lord,’ said Valthex, pressing a rune.

Garreon had been present when Huron Blackheart had salvaged the Implacable Stalker in the warp, and he now watched its demise. The galleon had been loaded with explosives, and at the press of Valthex’s rune the ship’s core was detonated, the hull blasted to blackened, burning fragments that rolled and tumbled across the Valley of Blades, destroying everything in their path. At the heart of the explosion, the Stalker was utterly destroyed. No Red Corsair had boarded the vessel since they reached the Hollow Worlds – it had always been marked for sacrifice, when required – and the loss of the mortal crew was nothing to Garreon. But to see an ancient vessel, so drenched in Chaos from its time in the warp, sacrificed in such a way was ruthless even by the standards of Huron Blackheart.

Huron Blackheart himself paid its demise no mind, turning to the crew of the Fist and barking out orders.

‘All engines full ahead,’ the Tyrant shouted. ‘Gunners, bring down those Whirlwinds. Shipmaster, hail the Strike and order it to set out to starboard, and order the Tireless Vengeance to turn to port. We sweep through this valley and leave nothing alive, or I’ll send you to the same fate the crew of the Stalker met, do I hear aye?’

The ‘aye’ that echoed out across the deck of the Unyielding Fist was nearly as loud as the Stalker’s fiery demise.

Folkvar could do nothing as Frozen Blade was caught in the blast from the exploding galleon, a noble tank of countless generations of service destroyed, its burning carcass rolling across the snow, crushing Tallarns and traitors alike. Further away, two enemy Predators were circling Ice Storm with murderous purpose, while a Vindicator lay on its side, the Chaos bikers moving in to engage the Space Wolves climbing out of the tank. Across the valley burning debris was falling from the sky, changing the shape of the battlefield, cutting off one tank from another. The scene was one of carnage, and the Red Corsairs were taking advantage, moving in with lethal intent.

‘This is Tempest,’ said a voice over the vox. ‘Firing on galleons but they’re coming in fa–’

The signal cut off with a hiss.

‘Bring us around, Garik,’ ordered Folkvar, and the Frost turned towards the mountain pass, where a galleon had swept out at three times the speed of its predecessor.

‘Witchcraft,’ spat Folkvar. This galleon moved with unnatural grace for a hulking ship dragging itself across the land. It bristled with cannons at either side, as well as a plentiful array of weaponry on deck, all of which peppered the walls of the valley with explosive ordnance. Avalanches were sweeping down both sides of the valley, the Whirlwinds either destroyed already or crushed as they tumbled to the ice.

‘Damn these traitors,’ said Folkvar. He knew now the galleon that had first entered the valley had been a sacrificial offering, durable to assault but far from being at the height of its powers. What he saw now was a galleon at full strength, a monstrous engine of destruction.

He was also sure from the smooth motion of the galleon, the commanding way it had swept into the valley, that this was the flagship. On board would be Huron Blackheart himself.

‘All Space Wolves and Tallarns, this is Folkvar,’ he commanded over the vox. ‘The enemy’s tricks are done with. Even if it was their intent that it should fall, they have shown us that these galleons can be stopped. So let us stop this one, board it, and spill the blood of our enemies.’

‘You heard Folkvar,’ said Hagen. ‘We take that galleon.’

‘I am not sure how much thread the Tooth has left,’ said Onora. Shattered Tooth had been caught at the edge of the explosion, and while runes flashed all around the cabin, each representing a part of the Vindicator that was badly damaged, the tank still functioned.

‘Then we make each moment of life count,’ snarled Hagen. ‘We fight as we have always fought, ’til the very end, and strike in memory of the Claw and all our fallen brothers.’

‘Aye, for the Claw,’ said Onora. While systems were failing, the Vindicator still had its speed, and the galleon ahead was moving fast across the valley. As the space between the two vehicles, the tank and the galleon, closed, gun batteries on the galleon began to open fire on them. The interior of the tank rattled and boomed with the fire from above.

‘Prepare to fire,’ snapped Hagen. ‘Take us around to the right. I want one of those wheels.’

With mortar and gunfire raining down from above, the Vindicator steered around the giant hulk. In most combat situations, the Vindicator was considered a brute of the battlefield, as its demolition of the Rhino had demonstrated. But compared to the vehicle towering over it, Hagen thought it must seem like a gnat, a tiny speck beneath the bulk of the Chaos ship.

However, thought Hagen as they pulled in close, it was a gnat with a powerful bite.

‘We’re falling apart,’ shouted Onora. The tank was filled with smoke, and light was entering its interior through holes blasted in it shell.

‘Bring us around,’ Hagen shouted back. ‘Charge that wheel.’

Onora steered sharply and put everything into one last burst of momentum, the tank hurtling towards one giant wheeled track of the galleon in its final moments.

‘Fire!’ screamed Hagen, and Shattered Tooth unleashed the full power of its demolisher shell the second before it hit the hull of its enemy.

At point-blank range, the explosion tore through one wheel and a large section of the galleon’s prow. The blast fed back on Shattered Tooth, ripping into the Vindicator and shredding its armour.

‘Hold steady,’ screamed Hagen as the blazing Vindicator kept moving towards the great ship. ‘We will see our brothers soon.’

On the deck of the Unyielding Fist, Garreon felt the entire ship shake beneath him, and the Fist begin to slow.

‘What was that?’ demanded Huron Blackheart, swinging the Tyrant’s Claw around, searching for an underling to impale.

‘We have the remains of a tank lodged in one wheel,’ said Valthex coolly. ‘More power to the rear wheels should shake loose the obstruction.’

Garreon looked out across the valley. Space Wolves tanks were convening on the Unyielding Fist.

‘They seek to halt our advance,’ snarled Huron. ‘All guns, all cannons, every crew member who can reach a portal – show them that Huron Blackheart cannot be so easily stopped.’

Fire rained down on Burning Frost as it approached the Chaos galleon, which was slowing down after the sacrifice of Shattered Tooth. Grenades and cruder explosives had been launched at the Land Raider from the galleon, while the smaller vehicles that swarmed around the ship shot missiles and las-fire in their direction, but none had so much as shaken the ancient tank on its chassis, although flashing control runes indicated to Folkvar that a number of fluid lines had been compromised.

Others in the pack had not been so lucky, and Folkvar had seen a Vindicator wrecked by suicidal, mutated mortals crashing a halftrack full of explosives into it.

No, the Frost was built of sterner material. It would take more than this to destroy it.

The Predator which was pursuing the Frost might just manage the kill. Covered in spikes and blasphemous sigils, it tried to dissuade the Frost from repeatedly firing on the slowed galleon. If not stopped quickly, Huron’s army would be out of the valley and beyond Folkvar’s reach.

‘Maintain fire on those tracks,’ Folkvar shouted as the Frost kept pace with the galleon while targeting it with both side-mounted lascannons.

The kill-urge ran through them all now, flowing not just from the blood of Russ in their veins, but from the Frost’s very spirit. It was a machine, but a machine of Fenris, and it was enraged to see so many of its pack shattered across the valley.

‘Evade!’ shouted Folkvar as the Predator targeted the Frost with its lascannon, and the Land Raider swerved away from the galleon, causing the lascannons to fire wild, missing the wheeled tracks and leaving a pattern of burns up the side of the galleon’s hull. The Predator fired, but missed the Frost. As it moved to target the Frost again, the Frost fired on the Predator with the heavy bolter.

It must have seemed to the crew of the Predator that the heavy bolt shell had fbeen poorly directed, as the shell didn’t hit the tank in the centre of its chassis but low near the tracks. It was only as the shell exploded that its purpose, and the precision of Folkvar’s targeting, became clear – the Predator was thrown off course by the blast, not enough to overturn the tank but enough to cause it to crash into another Predator just as it was about to fire.

The two tanks were too heavily armoured to be destroyed by the impact, but the crash was enough to rob them of any momentum, and they were left behind as the Frost moved back towards the galleon, firing on it once more with its lascannons.

‘Enough,’ snarled Huron Blackheart, looking over the edge of the galleon at the Land Raider below.

Three of the finest tanks in his command defeated, and one destroyed, by a single Land Raider. It was an insult that would not stand. No more.

‘My lord,’ said a voice from behind Huron. ‘Please allow me.’

Small-arms fire from the portholes of the galleon rained down on the Burning Frost, but with little consequence. It was no mere tank, and even the grenades that clumsily bounced off its roof barely scratched it as they exploded.

‘It’s close to stalling,’ roared Folkvar, within the Frost.

There was a solid clank from the roof of the Frost, presumably another shell or grenade thrown down, but no explosion followed.

Folkvar bellowed in rage and frustration.

‘Malfunction, possible grenade damage’ snarled Folkvar, drawing his bolt pistol and opening the hatch above him. ‘Going up-top to check.’

The Space Wolf who emerged from the hatch on top of the Land Raider was no fool, but then Taemar would have expected no less from the Vlka Fenryka. While the Red Corsair had some element of surprise, he knew it would only get him so far.

As the hatch cautiously opened, Taemar was waiting, boots magnetically locked to the roof. His axe had torn through vital servos in the base of the Frost’s heavy bolter, and was held high as the hatch opened.

The Space Wolf’s reactions were fluid and instantaneous, snapping off a round from the bolt pistol and then dropping back into the belly of the Land Raider, pulling the hatch behind him. The Space Wolves, for all their animal ferocity, never left themselves vulnerable unnecessarily, and would protect the pack within the machine rather than expose the vehicle’s interior by engaging the enemy directly.

It was an entirely admirable defensive manoeuvre, Taemar thought, but also entirely predictable. He had anticipated such a defence, and was ready to react, rolling under the Space Wolf’s line of fire and swinging the twin-bladed axe low.

The Space Wolf was too fast to be caught by Taemar’s axe, but then he was never the target. The blade of the axe jammed underneath the hatch as it closed, preventing it from fully locking. Taemar then lifted one boot from the roof of the Land Raider, and pressed his whole power-armour assisted body weight down onto the handle of the axe.

The axe strained, threatening to break, but it was a weapon forged by weaponsmiths of the warp, and had unnatural strength. The hatch cranked open, just a small amount.

Then it slammed back open, nearly knocking Taemar off the top of the tank. The Space Wolf who climbed out was fully armoured, but Taemar could tell from his movements that he was old, a warrior of great experience, purposeful in his attacks.

‘You boarded the wrong tank, traitor,’ said the old Space Wolf through an unusual grille in his helmet. He carried a hammer of his own, swinging it back and forth in one hand.

‘You command this vehicle?’ asked Taemar. He was already concentrating psychic energy into his axe, but it would take a few moments to build.

‘I command all these tanks,’ said the Space Wolf, swinging his hammer.

Taemar ducked back, making sure not to move too quickly. The hammer clipped the chestplate of his armour with a clank. ‘I am Folkvar.’

Taemar ducked under the next blow, letting himself be driven back, once more feeling the power building in his axe, drawing Folkvar in closer. Let the old Space Wolf’s bloodlust get the better of him.

Folkvar went for another swing, and this time Taemar rolled under the blow with great agility, causing Folkvar to stumble.

Taemar raised his axe, and brought it down and across in a two-handed swing. ‘I am Taemar,’ he replied. ‘And I command this axe.’

The blow Taemar delivered was loaded with psychic energy, which tore into Folkvar’s chestplate, the surge of power crackling over his armoured form. He screamed through the grille on his helmet, a guttural gurgle. Blood dripped from where a long gash had ripped through his upper body.

‘You will die here,’ said Taemar. ‘But you will watch all you command be destroyed before you do.’

He slammed the flat side of his axe into Folkvar’s body, knocking him off the Land Raider, and the old Space Wolf disappeared into the snow.

Taemar had a crude bag slung over one shoulder. He dropped the bag so he was holding it by the strap, then used his other hand to grasp a cord protruding from its mouth. He pulled the cord from the bag, bringing with it a small cluster of firing pins. Then he swung the bag into the open hatch on the Land Raider’s roof.

Taemar rolled off the top of the Land Raider, landing next to his axe on the icy ground below.

As the muted sound of an explosion came from the Land Raider, and it veered away with smoke pouring out of it, Taemar got to his feet and locked his axe to the back of his armour. Then he ran to reboard the Unyielding Fist.

Rotaka was one of the last Corsairs to survey the Valley of Blades before Huron’s convoy of vehicles moved on. He and his squad made one last circle of the battlefield, but found no signs of further life to extinguish, just burning tanks and scorched bodies. The Predator tanks and Huron’s mighty land galleons had ravaged the last remnants of the enemy forces as they swept through the valley. The unending white of the Valley of Blades was blemished by smoke, craters and twisted metal, the burned-out corpses of both loyalist and traitor vehicles scattered across the valley.

It had not been without cost, and as he drove back on board the galleon Merciless Strike, Rotaka took one last look back at the wreck of the Implacable Stalker, an ancient vessel destroyed to confuse and bewilder the enemy. Rotaka thought nothing of the mortals who had crewed the vehicle, but to cast aside such a large number of them in one blow had been a risk.

Yet it had worked, and while sacrificing vehicles and mortals Huron had not lost a single Red Corsair at the Valley of Blades. They had emerged from their first encounter with the Space Wolves without casualties, leaving nothing but ruin behind them.

Nothing would stop them reaching Karstveil.

Seventeen

The blind monks of the sunken monastery swore to live their lives away from a light they could never see. Underground, in a series of catacombs beneath one of Hacasta’s many mountain ranges, one hundred brothers prayed to a distant Emperor they could hardly envisage, spending their days in total darkness.

The blind monks did not miss the light, not because they were blind, but because they believed the only light worth contemplation was that of the Emperor Himself.

Nonetheless, repellent though it was to feel the touch of daylight on their pallid skin, someone had to be present at the monastery’s three cave entrances to receive supplies, or to receive rare visitors.

So, each monk spent a month at a time on one of the gates. The fortunate ones never had to open the heavy wooden doors, and remained untouched by the dreaded daylight.

Brother Perrit was on his last day of such a silent, dark vigil when the knocker slammed into the door, three times. He sighed wearily, stood up, and shuffled towards the door, the weighted hem of his robes rubbing against the flagstones. Wearily, he hauled out an aged flintlock, a relic of some long ago battle, and dragged it over to the door. There was a small hatch at head height for the monks to speak to visitors, but beneath that was a smaller, round hatch, invisible from the outside. Perrit lined the flintlock up with the small hatch, quietly moving a slider to open it, and slid in the barrel. He deactivated the safety on the flintlock, then opened the hatch, wincing as light touched his skin for the first time in decades.

Before Perrit could ask who was there, a voice from outside spoke. It was a deep, inhuman voice, metallic but with a pained, bubbling undertone. It was like no voice the monk had ever heard before.

‘Open this door,’ boomed the voice. ‘And stop pointing that gun at me, mortal.’

The voice rang with such fierce authority that Perrit dropped the gun, and his hand was halfway to opening the door when he realised he had no idea who was speaking to him.

‘Who–’ Perrit began, and was instantly cut off.

‘I am Folkvar of the Vlka Fenryka, loyal Chapter of the Emperor’s Adeptus Astartes,’ snarled the voice. ‘I have wounded with me. Now open this door before I kick it down.’

Brother Perrit considered the relative merits of the situation, and opened the door.

Anju Badya woke in a narrow cavern carved from rock. Crammed into the rest of the chamber, almost doubled up, was Folkvar, holding a flickering oil lamp in one hand, the gentle light flickering over the shovel-shaped grille of his helmet.

Badya licked her dry lips, preparing to speak. A naive person might have thanked Folkvar for saving her life, but Anju Badya had fought alongside the Space Wolves long enough to know that they had no interest in, or desire for, the gratitude of mortals; that they acted upon their own impulses and instincts, and anything else was irrelevant.

No, she didn’t need to thank Folkvar. He hadn’t dragged her out of the wreckage in the Valley of Blades and all the way to wherever they were now so she would thank him. He must have his own reasons, and as Badya couldn’t begin to guess what those were, she wanted to know. So she asked him, her voice a low croak.

‘I saved your life,’ Folkvar said, his deep, metallic growl reverberating in the rocky chamber. ‘Because you had survived.’

This seemed the wrong way around to Anju – surely she had survived because he had saved her life? She wondered if the Space Wolf had suffered some injury to the brain in the battle.

‘I survived because you saved my life,’ she said.

‘Fenrys Holdja! Do not presume to correct me,’ snarled Folkvar. ‘I know what I said, and I know what I meant. I saved you because you had already survived the battle when no one else had.’

After his earlier rebuke, Anju dared not speak again, instead waiting for Folkvar to elaborate:

‘You had clung on to life where so many of your kind, and so many of mine, had not. Great warriors, my brothers, died, the machine-spirits of our tanks snuffed out. Legends cut short.’

Folkvar raised a finger, pointing it at Anju. Whether in accusation, she did not know.

‘Yet you survived where they did not. And not for cowardice – you were closer to the heart of the battle than most. Yet here you live.’

There was no rancour in Folkvar’s voice, just a statement of fact. He lowered his hand. ‘To survive such a battle is exceptional,’ he said. ‘It would have been a waste to let such a thread be cut by the cold. Your wyrd has further battles to come.’

‘Badya,’ Anju said. It had not occurred to her before that Folkvar, who all in her squad had known and recognised, had brought her so far without knowing her name. ‘Sergeant Anju Badya.’

Folkvar nodded, and partially stood, placing the oil lamp on a low stone bench. He remained stooped – this underground world wasn’t built for the likes of his kind.

‘Well, Sergeant Badya,’ said Folkvar. ‘Rest well, recover. We still have battles ahead of us. I will go now to send word to our generals of the defeat we have suffered, but will return within two days. Then you and I will set out to find our next battle, and redress the balance, yes?’

Folkvar didn’t wait for an answer, but nodded and left, stooping even further to leave via a short wooden door.

It was good that he didn’t wait, as Anju had no answer to give. Two days it was, then.

Closing her eyes, she began to move her limbs, and test how close to recovery she was.

In the Gatehouse on Ressial, Dumas Cheng had almost become used to the presence of a member of the Inquisition. What he was not prepared for was finding Inquisitor Pranix seated on the system governor’s throne – Cheng’s throne.

This raised a difficult question of etiquette. Normally, Cheng would not have hesitated to respond to such insolence by having the offender killed. However, this was a holy inquisitor, who would doubtless respond to any such threat by killing Cheng with his bare hands.

So instead of summoning guards, Cheng approached his own throne slowly, as a supplicant. Pranix was still, sitting in the throne with his chin on one hand, but with the other hand moving, dangling a short strip of vellum and waving it back and forth.

‘A few corvids survive, system governor,’ said Pranix. ‘One such bird still lived, in a high hermitage on Hacasta, and has brought news.’

The inquisitor held out the vellum to Cheng, and impatiently gestured for the governor to take it.

Cheng looked at the vellum, then frowned. ‘This is nonsense,’ he said.

Pranix snatched the vellum back and stared at it.

‘Apologies, system governor,’ said Pranix. ‘I forgot that some people can’t sight decode a forty-three cycle cipher. Let me explain – this is a message from Folkvar.’

Pranix tossed the vellum into the air, and it fluttered down to the flagstones like a ribbon on reconstitution day.

If that dismissive gesture confirmed that Folkvar’s tanks had been defeated, then it was no surprise to Cheng. Communication with Folkvar had ceased many days ago, when the Space Wolves had assembled their tanks at the Valley of Blades.

‘The Space Wolves were defeated on Hacasta,’ said Pranix, redundantly. ‘Two survivors, Folkvar and one of the Tallarns. Our only significant armoured divisions have been obliterated, and only a few exhausted Cadians and the Ironshore stand between the traitors and the Orrery.’

‘The Ironshore has considerable defences–’ began Cheng wearily, before the entirely expected interruption.

‘Doubtless. But I have underestimated Huron Blackheart once already – I am loathe to do so again,’ said Pranix.

‘I should have committed my entire force to Hacasta,’ said Pranix, barely addressing the system governor now. ‘What use are these Space Wolves, dug in here?’ He waved one hand in an airy gesture, indicating the Space Wolves who had fortified the Gatehouse.

Dug in, thought Cheng. Dug in. He looked out of the window. It was a quiet morning outside, pallid light filtering down through the high, narrow windows into the throne room. The twisted spires of the Onyx Palace, the Emperor’s never-occupied Lastrati residence, dominated the skyline.

‘Perhaps they’ve just been digging in the wrong place, inquisitor,’ said Cheng.

‘Now that is a cypher I cannot translate, system governor,’ said Pranix, whose sarcasm had become more withering the longer he resided in the Gatehouse. ‘So please humour me with a clearer explanation.’

‘There is a legend concerning the Onyx Palace,’ said Cheng, still looking at the spires. ‘I always thought it was simply that, a legend, but under these dire circumstances even a faint hope from myth might be–’

‘Tell me the story,’ said Pranix.

Cheng turned to see that the inquisitor was sitting forwards on the system governor’s throne, fingers steepled, attentive.

So Cheng told him the legend, and Pranix became more attentive still.

‘Find it,’ he said, when Cheng had finished.

‘It could be anywhere under the Onyx Palace,’ said Cheng. ‘And we have no–’

‘Then we tear the palace apart until we find a clue, and wherever that clue points to we start digging. Multiple teams, heavy movers, every servant and servitor we can find. Raze the palace with explosives if that helps.’

‘Lord inquisitor,’ cautioned Cheng, ‘the Onyx Palace is the Emperor’s residence – to damage it would be considered heresy.’

Pranix was silent for a few seconds, then spoke in a very low voice which nonetheless reverberated around the empty throne room. ‘I am the inquisitor here, Lord Cheng,’ he said. ‘And I decide what is heresy and what is necessity. This is necessity.’

‘Very well,’ said Cheng, with a brief bow of his head. ‘I will give the orders.’

He paused, holding Pranix’s gaze. The inquisitor was dangerous; still, he had been brought low, and it was only by telling an old tale that Cheng had revived Pranix from his lethargy. For all his power, the inquisitor was not infallible.

‘I am glad to see you energised, lord inquisitor,’ said Cheng.

‘And I am glad you hold such concern for my humours, system governor,’ replied Pranix unblinking.

Cheng gave another bow. ‘Excellent,’ he said. ‘In this new spirit of activity I will prepare a plan of exploratory demolition works.’ He paused, a smirk teasing the edge of his mouth. ‘While you can work on getting out of my throne, my lord inquisitor.’

Then he turned and left before Pranix had time to reply.

The waypoint was to be one of many, a series of secured bunkers across the wastes of Hacasta, a string of Red Corsairs bases between the Archway to Karstveil and the Archway to Kerresh. The work of construction was being done by servitors and mortal slaves, but the Corpsemaster did not trust any task to feeble mortals alone, no matter how terrified or fanatically loyal.

So Capulo of the Red Corsairs, veteran of a thousand battles on a hundred worlds, found himself in the middle of faceless tundra, staring out into a blizzard as slaves struggled to work and survive in the hostile environment.

To Capulo, such an environment was no danger, at worst a discomfort, and his power armour made it even less than that. He looked on the mortals dispassionately as another one died, keeling over into the snow.

‘Clear the body,’ he ordered two of the other slaves. ‘Get it out of the way and get back to work.’

The slaves disappeared from Capulo’s vision, consumed by the blizzard. He waited for them to return, monitoring his surroundings for any threat, certain that none would come. The action was elsewhere. He and his squad would follow their orders, establish one waypoint after another, waiting for the day when they would see true combat again. Capulo resented being left behind as Huron’s fleet of land galleons rolled on to Karstveil – that was where the battle would be.

He shouted out into the snowstorm for the slaves to get back to work.

Capulo was a creature of violence, and in the absence of violent acts to commit, the Red Corsair waited impatiently, alert to his next target. He had slaughtered the enemies of man, then the enemies of Huron. The enemies changed; war did not.

‘Shouting at the weather?’ boomed a nearby voice. Trantor, his second.

Capulo didn’t even turn to look at him. ‘The mortals,’ spat Capulo. ‘They keep dying.’

‘Feeble,’ said Trantor, stomping through the snow towards his captain. ‘Do you remember that battle on Kerresh?’

‘Yes,’ Capulo replied. He did not mention that Kerresh had been so recent. An injury to the head had damaged Trantor’s memory, leaving the difference between yesterday and a decade ago indistinct.

‘That was true combat,’ Trantor said. ‘We took that factorum with steel and fury. Fighting hordes of skitarii while evading the gears and pistons of great machines. You were nearly crushed. Such times.’

Trantor shook his head as if it had been years ago.

‘I emptied my bolter of ammunition, and had to fight on with my fists alone,’ said Capulo. ‘I ended the day with my armour crusted with dried blood, throwing mortals into a cauldron of liquid metal to be boiled alive.’

‘You remember it so well,’ exclaimed Trantor. ‘Such a battle, better than patrolling this desolate hole.’

Trantor resumed his patrol, lost in distant memories of recent times, leaving Capulo to wonder why the slaves had taken so long disposing of the body. He raised his bolter. While it was entirely possible that the slaves had themselves frozen to death while dragging the corpse, Capulo took nothing for granted. Readiness was woven into his being.

As such, when it came for him, charging out of the blizzard, Capulo was not taken by surprise or caught unawares. A power-armoured figure, draped with furs and wielding a power fist, emerged from the snow at high speed; Capulo simultaneously dropped back into a defensive position, raised his bolter and opened a vox-channel to alert the rest of his squad.

He reacted perfectly, without fear or hesitation, yet it did him no good.

The power fist smashed into Capulo’s face, denting the front of his helmet and breaking his nose. The words he was about to speak into the vox were cut off as the interior of his own helmet hit him in the mouth. As the blow made contact, Capulo was knocked backwards, a single bolter round firing wide, missing any targets.

Capulo didn’t fall; he spun on his heels, bringing his own gauntleted fist around to punch under his attacker’s power fist, ceramite smashing into ceramite as his armoured knuckles hit the other’s power armour just below the ribs. It was enough of a blow to knock Capulo’s assailant back a step, allowing the Red Corsair to raise his bolter once more. At this range, one shot from a bolter would stop even a Space Marine in his tracks, if not cause serious damage to the Space Wolf’s armour.

That shot never happened, as before Capulo could squeeze the trigger, the blade of a power claw dug into his wrist, slipping between the plate of his power armour to cut into muscle, wedging between the bones of Capulo’s wrist. The pain, searing as it was, could not stop Capulo, but the muscles in his hand involuntarily released their grip on his bolter.

The bolter fell to the snowy ground, and as the second assailant removed his blade from Capulo’s wrist, a third kicked the Red Corsair in the back of one knee, bringing him crashing down to his knees. His bolter was kicked away before he could reach for it with his good hand, and a second blow from the red power fist left his senses swimming and warning runes flashing across his helmet display.

As his helmet was pulled away, Capulo looked out through bleary vision, his head swimming through the pain of the blows. Three attackers encircled him, prowling around as he slumped, trying to regain the focus to stand, to fight back. Behind those three, he could see more of the Space Wolves, figures as large as himself but with a feral gait alien to the Red Corsairs, their shoulders hunched and draped in furs, yellow eyes glowing in faces cast into darkness as the blizzard blurred his vision further.

This was not combat, this was a massacre. The Space Wolves had come in great numbers to tear apart Capulo and the others at this waypoint.

When they were done with him, and the last of his long life was draining from his body, Capulo was left face down in the snow of Hacasta, the blizzard beginning to cover his prone form before he was even truly dead.

Capulo’s last thought, as he dimly heard his assailants stalk away to kill anyone else they found, was that, yes, the mortals had been right: it was cold here.

The Space Wolves came from all directions, wielding claws and chainswords and their bare hands, and they descended upon every living thing on that site with wordless fury. They all had names, but those names were irrelevant. They hunted as a pack and were of one mind as they hunted.

Like any pack, they knew that the strongest threats should be eliminated first. With one Corsair already dead, they sought to kill the others quietly and stealthily with the caution required to deal with Adeptus Astartes, even corrupted ones.

They pursued the Corsair who had been speaking to the traitor they had already killed. Three Space Wolves ran through the blizzard, as light on the ground as a breeze, noiseless in spite of their heavy armour. Two grabbed the Corsair by the arms, while the third jumped on his back. His bolter was out of his hand as they forced him face down into the snow. The snow muffled the shot to the back of the head that finished him off.

Three more. Another was keeping watch on the wall of the semi-constructed bunker. Two of the pack sidled around the wall, clambering up to pounce and drag him down. Another heard the disturbance, and found a knife in his throat.

Which left one. He stood at the centre of the construction site, surrounded by slaves and servitors working on the waypoint. At the sight of the Space Wolves looking down on him from the half-built walls, the sight of their yellow eyes and bared fangs, the renegade raised his bolter, only to have it knocked from his hand with a well thrown axe.

The pack jumped down to surround the last Red Corsair. He drew a knife, and defended himself. As the Space Wolves lashed out at him with claws and blades, he slashed back, he drew blood. He fought with the ferocity of all his kind, but it was not enough. Blows slipped past his defences, raining down on him. He continued to fight as he fell to his knees, his armour stripped away by the pack, his attempts to block their blows increasingly sluggish, until he too died, cut down by the Space Wolves.

The Red Corsairs all dead, the mortal slaves were left as easy prey. Having watched one of their masters slaughtered before their eyes, they were gripped by frenzy. Some of them begged, or prayed to either old gods or the Red Corsairs themselves to save their lives. Some even sought redemption, asking forgiveness from the Emperor.

Such entreaties were wasted. All were tainted, so none were spared. As the winds howled, screams emanated from the site of the Red Corsairs’ waypoint, echoing across the wastes, unheard by any living soul.

When their blood had been spilt, the Space Wolves destroyed the parts of the waypoint that had already been built, demolishing and setting ablaze the entire site.

Nothing was left when they had finished, nothing but scorched rubble and corpses, black smoke tainting the endless white snow.

The Space Wolves, their work done without a word spoken, moved as one pack back into the icy hold of the blizzard, into the hostile cold that was their home and protection, moving away from the site of their slaughter, towards their next target.

To the Archway.

To Kerresh.

Eighteen

It was a world of sea and storms.

Whether by ancient design or a failure of the artificial atmosphere, Karstveil was gripped by never-ending storms. Rain, thunder and lightning crashed down on the turbulent seas that consumed most of the planet’s interior, and hammered the few clumps of rugged land.

Those few, brutish landmasses that dared rise above sea level had blunt, descriptive names, simple compounds that told their whole story in a name:

Archrock.

Strongwall.

Ironshore.

It was towards that final, fortified island that the black galleons of Huron Blackheart set out, sliding off the shores of Archrock and plunging into the rough waters of the ocean. Those galleons had rolled through the nearby Archway to Hacasta on great oily wheeled tracks, but as they approached the water those tracks disappeared into each galleon’s hull as if they had never been, the rusty, riveted metal sealing behind them like a healing wound.

While they had travelled a long way on land, the daemonic galleons were creatures of the water, and even in those unforgiving waters the great, hulking vessels took on a kind of grace as they left land behind, leaning perilously as the waves rose and fell but never capsizing, always moving with the tidal flow. Even travelling through toxic fog, the seas polluted with scum and flotsam, they cut through the filth smoothly.

As the rains of Karstveil dampened the embers of burning Archrock, razed by the Red Corsairs as they passed through on their way to the sea, the galleons of Huron Blackheart disappeared into the distance, setting sail across an ocean as big as the world.

Since the death of his commanding officer, Colonel Ruthger, Lieutenant Nistal of the Cadian 301st had drunk deep from the poisoned chalice of spontaneous field promotion, and was sick of it.

While he would not have wished to change places with the late colonel – self-pity was not a Cadian trait – Nistal did not relish the legacy Ruthger had left him with. While he was comfortable enough leading men on the battlefield, making decisions that meant life or death for those under his command, Nistal was less prepared to take command of a regiment reduced to a third of its original numbers, fighting a defensive war across a system of inside-out planets.

Since Ruthger’s death, all Nistal could do was make the big decisions for his regiment in the same manner he would make snap decisions on the battlefield – prioritise targets and defensive positions based on incoming intelligence.

The order supplied by one of the system governor’s corvids was that whatever lay behind the fortifications of Ironshore needed defending. Having established defences and traps on Kerresh to welcome the Red Corsairs once they reopened the Archway, Nistal had led his men to Karstveil, and to Ironshore.

What lay within the mountain at the heart of the rocky island of Ironshore, behind apparently impassable gates, Nistal had not been made privy.

Fine – Nistal had his objective to defend, that was all that mattered, and he didn’t need to know any more. The jagged mountain, the top of which disappeared into the relentless cloud and fog, would only be reached once every Cadian under Nistal’s command had laid down his or her life in its defence.

Grim thoughts came naturally on Karstveil. The peak sat at the centre of the Ironshore, and the island was rimmed by the towering defensive wall that gave the island its name. That outer wall was made of an iron-like material of unidentified source, and was completely unbroken and impenetrable, to the extent the Cadians had been forced to cross over the wall to get in, a complex device of connected ladders lowering down to allow them access. On the inside of the wall generations of defenders had built scaffolding to access the top of the wall, but there were no firing slits or fixed weapons on the wall itself.

‘Hammer a nail into the wall,’ said one of the Lastrati who greeted them, ‘and the wall will push it out again.’

Between the wall and the mountain at the island’s centre there was little but grey rock, grey fortifications made from the grey rock, and grey buildings built from grey rock and mostly built into the grey fortifications.

Then there was the sky, a mass of different cloud types, illuminated by lightning and soundtracked by thunder, and forever spilling forth rain. Ironshore was built to cope with the rain but it gathered in every dip in the rocky land nonetheless, becoming filthy with mud and the oily residue of the work that took place in Ironshore’s maintenance yards.

‘Lovely weather we’re having,’ said Sergeant Murso as Nistal approached, the rain hammering against his waterproof cloak.

‘Sir,’ Nistal snapped back. ‘This place might not help morale, but rank still applies.’

‘Apologies, lieutenant-sir,’ said Murso, blurring rank and honorific into one word. She was smoking a lho-stick in the sheltered porch area outside the door to a barracks hut. Nistal joined her, took the lho-stick without asking, had a drag on it then handed it back.

‘That showed me, sir,’ said Murso, a crooked grin breaking across her scarred features. Nistal had known Murso for years, although not so long as to have seen the sergeant get those three vicious scars on her face. They had been the same rank together, once, but taken different paths. In some sense, they would always be equals, regardless of what rank dictated.

‘And me,’ replied Nistal, leaning against the wall and coughing fiercely. ‘That stuff is foul. How are the defences?’

‘The Lastrati keep their gun batteries in good shape,’ said Murso. ‘The enemy will need to get in close.’

‘We need to know when they’re coming,’ said Nistal.

‘That’s the bad news,’ said Murso, exhaling lho-smoke. ‘These storms interfere with every means of detection equipment we have apart from these.’ She pointed two fingers at her own eyes.

‘How is that even possible?’ asked Nistal.

‘No one knows,’ said Murso. ‘But the locals have their suspicions.’ She nodded towards the centre of the island, the mountain and those great, closed doors.

‘That which we defend interferes with our defence,’ said Nistal. ‘Great. How’s morale?’

Murso hesitated.

‘That bad?’ said Nistal. ‘I never thought I’d have to order you to speak freely, Murso. Spit it out.’

‘They have snipers here to take out people who try to kill themselves by climbing the lightning conductors,’ said Murso. ‘It’s a full-time job. The ones who throw themselves into the sea are less of a problem, as they won’t damage any Imperial property on the way down.’

She looked seriously at Nistal.

‘That’s what this planet does. It’s not a death world but it strips you of the will to live. Losing Ruthger took its toll, and this place doesn’t help,’ said Murso. ‘But they’re still the Three Hundred and First, and there isn’t one amongst them who wouldn’t follow you when the time comes. Ignore their bloody moaning – everyone will have your back when the enemy gets here.’

Murso leaned out, looking up into the rain. Fat raindrops spattered her face, but she stared unblinking.

‘Most of us just wish the sods would hurry up and get here before we drown.’

In the belly of the galleon Merciless Strike, Rotaka had found himself prowling the depths of the ship with his servo-skull for company, staying out of the way of both the crew and other Red Corsairs. He preferred his own thoughts to the company of others.

The cargo holds were the best place. The Strike carried mainly siege equipment, as well as artefacts the Red Corsairs had brought with them in case they were needed, weapons of the warp sealed in lead containers daubed in wards and symbols to calm their restless, daemonic spirits. Then there was the crate, although ‘crate’ barely covered its huge scale. A box made from multiple layers of armour plate, encircled in chains and sealed with powerful wards and symbols, it towered over Rotaka.

Mostly, the crate remained silent. But every now and then it would jerk to one side with a thump, as if something inside were having a nightmare, lashing out in its sleep.

Rotaka leaned in, and listened to the sound within the box, sounds inaudible to mortal ears. ‘Of course,’ he said. ‘I had almost forgotten.’

Then he barked a laugh at some re-emerging memory. ‘Iltz, do you remember when…’

He trailed off. Iltz was dead. The thing floating next to him was just Iltz’s skull.

The thing in the box wouldn’t remember either. Only Rotaka remembered, and he should forget. Those days were long gone. The Astral Claws were a part of the past, and Rotaka needed to remember that. What was he now?

Such thoughts were uncomfortable for a Space Marine, forged for waging single-purposed war, without hesitation or restraint.

It was with great relief that his thoughts were interrupted by an explosion that rocked the entire ship, followed by the ringing of alarm klaxons.

They were under attack.

From the deck of the Unyielding Fist, Valthex knew exactly the nature of the attack. He had seen it himself, the explosion from the water level, the brief plume of flame against the hull of the Strike. It meant only one thing, and looking out to sea confirmed it.

‘Mines,’ he told Huron Blackheart, who bestrode the deck relaying orders to his crew and, via vox, the rest of his fleet.

‘If there are mines,’ Huron Blackheart said. ‘Then we are close. Still all engines and bring to.’

The Fist stopped its engines, and although momentum carried them a little forwards, and the heavy waves dragged the galleons back and forth, there were no reports of another galleon striking a mine.

‘Garreon, bring out the mine hunters,’ Huron told the Corpsemaster. ‘Prepare flares for first detonation, and ready main guns.’

A group of mortals were brought on deck. Their bodies had been bound in lightweight, insulated material so that they would not die of hypothermia before serving their purpose. The scars on their bodies, and their dead-eyed expressions spoke to Garreon’s work on them in his dungeons. Grenades hung on straps around their torsos.

‘You have all failed your master,’ said Garreon. ‘Now you will redeem yourself in death. Swim out, find the mines. If they do not detonate at your embrace, use grenades.’

The mortals did not acknowledge the order but ran and fearlessly jumped off the deck. Valthex could see the other mortal crewmembers on deck shifting restlessly.

‘This honour awaits all who fail Huron Blackheart,’ shouted Garreon. Valthex had known the Corpsemaster for centuries, and Garreon could measure human fear with the same precision Valthex’s equipment monitored radiation. Not that Valthex’s instruments could measure much in the fog of Karstveil, which disrupted all augurs.

‘Eyes on the horizon,’ Huron hissed. ‘These are their seas – they won’t be far. Valthex, the arrays.’

‘Still nothing, my lord,’ replied Valthex. ‘These storms…’

‘The Orrery infuses this world with disruptive power,’ said Huron, his naked lust for a treasure nearby overriding any rage at the equipment failure. ‘It defeats even my sorcerers. Such power.’

Valthex watched Blackheart. A dead man walking, tainted with madness and in danger of losing his self entirely, yet the call of battle always revived him. Here, out in hostile seas, rain lashing the dead grey flesh of his face, Huron Blackheart seemed strangely alive.

There were a string of explosions out at sea. The mortals had found the mines.

‘The enemy will be close, just beyond the mines,’ said Huron. ‘Light the sky so we might see them.’

A dozen flares were launched from the deck of the Fist, matched by more from the others in the Red Corsairs fleet. The flares arced high into the air, red streaks of smoke trailing behind them in the darkness, flying far out over the sea, well beyond where the mines had exploded. Sputtering in the relentless rain, the flares fell, dozens of points of red light illuminating the sea far beyond the normal visibility.

And there they were, warships of the Imperium, at least half a dozen. Brutish gunmetal-grey vessels with lascannons, heavy bolters and other weaponry on deck.

‘Target and fire,’ raged Huron, spitting out the words. ‘Before they can react, before those flares go out, target and fire damn you.’

The large cannon on board the Fist’s deck fired, a shell streaking across to the nearest Imperial ship. Valthex watched it cut through the air, knowing from his own instant, instinctive calculations that it would find its mark. The shell hit the hull of the Imperial ship just below deck level, an explosion throwing out water and debris.

The smaller weapons batteries on the deck of the Fist were also opening fire, and the nearest two galleons, Tireless Vengeance and Endless Fury, joined the salvo, lighting up the sea between the galleons and the Imperium ships. The Merciless Strike was out of sight, somewhere in the fog.

The Imperial ships were returning fire now, while making evasive manoeuvres. Bursts of heavy las-fire were superheating the air.

‘Bring us around to that ship we hit,’ called Huron Blackheart, ‘and prepare all guns to starboard.’

The order was relayed, and the Fist pursued the Imperial ship, which was now listing due to the smoking hole in its hull. The Fist moved out of range of heavy las-fire from the other ships, curving around so that the shelled ship was to the right of Huron’s flagship. The deck tilted as the Fist moved, and Valthex let himself tilt with it.

‘They’re targeting us!’ came a shout from across the deck.

‘Then bring them down first!’ bellowed Huron.

Any response the crew might have made was drowned out by the sound of every weapon on deck, and all the guns protruding from the side of the Fist, firing at once, a blaze of smoke trails and las-fire obscuring any sight of the enemy ship.

When the smoke cleared, the shattered ship was capsizing, taking on water at tremendous speed.

The crew of the Unyielding Fist roared in victory, a cheer that was only dampened by the sight of two more Imperial ships moving towards them at speed.

‘Sorcerer!’ Huron Blackheart bellowed. ‘Where are you?’

‘My lord,’ Anto replied. He moved across the deck of the Unyielding Fist with unhurried steps. While Huron valued obedience, he also despised signs of weakness. Any lack of confidence Anto displayed in his own abilities would fuel Huron’s doubts as to Anto’s usefulness.

‘Destroy these ships for me,’ ordered Huron, pointing the Tyrant’s Claw out to sea where two Imperial vessels were charting an intercept course with the Fist.

The Tyrant looked at Anto with a cruel leer. What he was asking was not easy; even sorcery had its limits, and to attack two such large targets individually, while compensating for the rising and falling waves…

‘As you will, my lord,’ said Anto, and he walked to the prow of the ship, then stared down into the turbulent waters below. He closed his eyes, and reached down beneath the deeps, stretching out with his powers. He muttered words of incantation, forming an unnatural storm, not in the sky but beneath the waves.

A cacophony of weapons fire broke out near him. He could feel the impact of shells and shot hitting the deck, the heating of the air round him as fire was given and returned. Huron was barking orders.

Anto kept his eyes closed, even as a bolt exploded against his armour. His focus was on the storm. It would not affect the two enemy ships directly, but then such a storm would do little direct damage to ships of their size. Instead, the storm was creating unnatural currents, changing the course of the waves.

‘Evasive manoeuvres,’ Huron shouted. ‘Turn to starboard.’

There was a brief moment before Valthex replied. ‘Bridge reporting we’re turning to port,’ said the Techmarine, a rare bafflement in his voice. ‘They’re saying they’ve lost control.’

Anto could feel the movement himself now. He was sure they all could. The Unyielding Fist turning to port, being forced to spin slowly.

‘The waters are rising!’ a mortal shouted over the continued gunfire.

Anto began to slowly raise his staff, and opened his eyes to see what he had wrought.

The Unyielding Fist was moving, spinning slowly as the rising waves pushed stern and prow, but it was a point of relative calm. The sea around the galleon was moving faster still, waters flowing around the ship in a circular motion, those waves rising higher. Anto could see the two Imperial ships caught in the rising waves, being pushed along with them. Las-fire and shells still rained down on and around the Fist, but as the Imperium ships were thrown sideways their aim was poor.

‘Cease fire,’ shouted Huron. ‘Cease fire and brace.’

The Fist was in a faster spin now, lurching in its rotation, but it was nothing compared to the two ships at the edge of the vortex. The churning waters were frothing white, rising higher than the deck of the Fist, the roar of the unnatural waves drowning out any other sound. The two Imperium ships circled the Fist five times, thrown closer and closer together, capsizing as ferocious water consumed them.

On the sixth turn they collided, the force of the sorcerous waves smashing the two vessels together. An explosion erupted in the wall of white water encircling the Fist, shattered fragments of the two ships dragged away by the waves.

As the ships were destroyed, Anto dropped to one knee and slammed his palm against the deck, whispering an incantation to dismiss the storm deep below the waves.

The Fist stopped spinning, the wall of water around it collapsing straight down, the normal tidal forces reasserting their control.

Anto bowed his head, the exertion of what he had just achieved rattling his every nerve ending.

‘Well, sorcerer,’ said Huron Blackheart, looking out at the wreckage of the enemy ships floating past. ‘You may prove to be of some use after all.’

Briefly, for a matter of a few minutes, the storm ceased. A freak moment of calm, it allowed the clouds to part and the sun to shine down upon the seas, which settled.

Valthex looked briefly at Huron Blackheart, and wondered if this was some new manifestation of Huron’s pact with his gods, and whether it was related to the Tyrant’s increasing daemonic aspect.

Then he looked back out to sea. As clouds raced away across the sky, visibility was total. One of the Red Corsairs galleons, the Tireless Vengeance, had sunk, but the rest survived. The Imperium vessels had not been so fortunate, and aside from a single ship, retreating into the distance, the sea around them was dotted with smoking and broken vessels, most of which were leaning at an unhealthy angle as they began to take on water and sink beneath the waves.

‘Main gun,’ Huron shouted. ‘Target that ship. I will have no survivors crawling away from here.’

The crew scrambled on deck, and with a grinding of gears and chains the barrel of the great cannon was cranked into position, its shadow now cast across the floor. When the great gun fired the noise shook everything, and after the blast there was a brief silence. The shell streaked through the air, trailing smoke.

The shell hit the distant ship, which began to sink.

As it sank, something could be seen on the horizon.

Land, or something built on it. A solid strip above the waves, shining in the unexpected sun.

‘Ironshore,’ hissed Huron, so quietly only Valthex could hear him. Then Blackheart turned to shout orders and abuse at the galleon’s mortal captain, demanding they set a course directly for that distant land.

The raindrops began to fall once more, the wind picking up. Within seconds the brief calm was over, and they were deep in the storm once more.

It didn’t matter. They had sighted land, and the fleet that protected it was now gone. No storm could stop them now.

Nistal took his eye away from the scope as the storm descended once more. It was a hugely oversized device, mounted on an extendable tripod that reached out over the wall of the Ironshore.

Even through such a scope, he had seen enough in those moments of clear visibility.

The traitors were coming, and only the Ironshore stood between them and the Orrery.

Nineteen

‘I had almost forgotten what it was to be a god,’ said Kruvan.

‘What was that?’ shouted Skarrow from the other end of the ridge runner carriage.

Kruvan had not realised he had spoken out loud. He shrugged his wide shoulders in Skarrow’s direction, and Skarrow took this as a sign that no conversation needed to happen. The other Red Corsair returned to polishing his bolter as the ridge runner continued its progress across Kerresh. From high on the ridge Kruvan looked down on an endless stretch of factorums and refineries, smokestacks and outlets spewing smog into the air, making it hard to see the planet curving up on the horizon. As Kruvan looked out, he saw the saltire of the Red Corsairs splattered across a tower.

It had been many years since Kruvan had known a population bow down before him and his ilk.

On the worlds of the Badab System, the Astral Claws had been tyrant deities, Huron demanding total subjugation from the mortals. Kruvan had walked amongst mortal men, and seen their terror and awe. Sometimes, they bowed, or presented tribute.

It was all worthless, of course. The Adeptus Astartes had no need or desire for mortal comforts, for their treasures or their currency. But to be looked up to in such a way, that had been good.

Then the Imperium crushed them. Badab was lost. The Astral Claws were no more. Amongst the forces of Chaos, the Red Corsairs were just one faction, regarding each other with fear and suspicion. It wasn’t the same.

Kruvan hadn’t realised how much he missed the old days until the Red Corsairs broke the population of Kerresh to their will.

To be a Red Corsair on Kerresh was to be the avatar of the new gods who had deposed the Emperor from His position as object of the people’s faith. When Garreon sent Kruvan, Skarrow and the rest of their squad out to the towns and factorums of Kerresh to gather slaves or resources, they had found themselves greeted with grovelling reverence. Weapons, fuel, food and drink, medical supplies: all were handed over without a shot being fired. The sigils of Chaos burned out from desecrated monuments to the old regime, the word of Chaos spreading to places the Red Corsairs had not previously visited.

It was not just the same as it had been on Badab, it was better, the authority of the Red Corsairs reinforced by the fire and fury of Chaos. From such a base, with the factorums of Kerresh and the population of the Hollow Worlds at their bidding, the Red Corsairs could expand, build a new empire, one the Imperium could not touch.

It was a dream, but one Kruvan knew he was not alone in having, a shared vision of a new Badab, of the Red Corsairs becoming conquerors of worlds once more.

It was a dangerous dream to speak of, even to a close comrade such as Skarrow. It echoed days officially struck from the memory of the warband, of the history of the Astral Claws that the Tyrant rejected in his new identity. Even with Huron Blackheart on the front lines elsewhere in the system, on Kerresh there remained Garreon the Corpsemaster, his loyal right hand, and dissent could never be spoken within his hearing.

But that hunger remained.

Kruvan and his squad’s last sojourn into the depths of Kerresh had taken a matter of days, and now they were returning to Garreon’s base of operations near the Archway to Hacasta. They came with a ridge runner loaded with supplies for the Red Corsairs war machine, with promethium and other resources for Garreon’s defence of the Archway.

While communication had been received from Huron Blackheart’s fleet of galleons before they departed Hacasta for Karstveil, other sorties into the heart of Hacasta had not returned, consumed by the blizzard with no trace. Expeditions to discover what had happened had not returned either.

Something was out there, picking off the Red Corsairs’ incursions into Hacasta. It could only be the Space Wolves, the Corpse-Emperor’s hated, bestial executioners. Kruvan did not fear the Space Wolves. None of the Corsairs did. And yet, the fact that the Fenrisians had yet to make a direct attack on the Corsairs’ position was… unnerving.

As the ridge runner slowed near the Archway, Kruvan could see that the portal to Hacasta was closed, the arch resembling nothing more than a stone structure, taller than even the ridges. This was a frequent occurrence: whatever alignment of Kerresh and Hacasta that allowed the Archway to work only lasted for a few short hours each day. The alignment was due to occur soon, as the area around the Archway was a hive of activity, mortals moving supply vehicles, fuel canisters and crates into position. Gun emplacements overlooked the work, barrels targeted at the Archway in case of incursion, and down among the workers walked Corsairs, towering over the mortals.

They looked busy, mortals and Corsairs, as the ridge runner came to a halt overlooking the loading area, the first carriage docking into a station built over the ridge. It was to that station that all who worked below would occasionally look up to. Nervously in the case of the mortals, with stoic reticence in the case of the Corsairs, because from the twisted tower that reached up from the station, Garreon the Corpsemaster commanded – and it did not do to displease him.

The Onyx Palace was visible from virtually anywhere on Ressial. So, when the towers of the palace began to fall, Kretschman saw it happen, even though he was standing on a mountain halfway across the continent.

The Mountains of Dyap was an area of vulnerability, should the Red Corsairs breach the Archway to Ressial and take the mountain route to avoid the coastal defences. Kretschman had been assigned to a Lastrati Guard platoon sent to establish traps, defences and outposts around the mountain passes.

After the stifling political atmosphere of the Gatehouse, even the thin air up in the mountains was preferable, and Kretschman began to feel like a true Cadian again, marching alongside fellow soldiers in the wilderness, sleeping on rough ground and eating standard rations. Away from luxury, he became himself once more.

He wasn’t the only one to see it, and they slowed to a halt as a murmur of alarm passed up and down the line of Lastrati, with the obvious conclusions jumped to: that the throne world was already under attack, the enemy had reached the Gatehouse, and instead of being there to defend it these sons and daughters of the Hollow Worlds were stuck up a mountain, away from the action.

‘Stopped to admire the view, have we?’ bellowed an officer from further ahead, before being drowned out by belligerent chatter.

‘Controlled demolition, we were warned about it last night,’ said the officer. ‘Word-by-bird. We were also ordered to ignore it and stick to our mission. Seems they knew you idiots would want to run straight back the moment you saw the first big bang. Clever old command, huh? Now get marching before I have to drop one of you over the edge to encourage the rest.’

As they resumed marching, Kretschman returned his eyes to the path ahead. Word-by-bird the officer had said, a message from the system governor’s network. With only the Space Wolves having conventional communications, the birds took days to pass a message on, so this must have been well planned, presumably the inquisitor’s idea.

But what was the point of demolishing a palace dedicated to the Emperor in the middle of a war? Not only did it seem pointless, but such vandalism seemed like heresy.

Kretschman shook his head and concentrated on marching. It wasn’t his concern. It had never been his concern, really; he had just been dragged into the strategising of the inquisitor, the system governor, and all those other high-ups by an accident of fate. Now he was back amongst the ranks where he belonged, even if they weren’t the ranks of his own regiment, and he would probably never see Inquisitor Pranix again.

Even as Kretschman thought that, he had a horrible feeling it wasn’t true.

‘Prepare,’ said the voice of Garreon, coming from vox-casters around the loading area. ‘If the hounds run through, I want them cut down before they can bite.’

Kruvan looked up at the tower in which Garreon resided, giving out orders. There was a great clock on the tower, but its gargoyle-festooned dial did not tell conventional time, or divide the day and night cycle within Kerresh. Its sole purpose was to count down to the periods when the Archway to Hacasta opened and closed.

The great hand, a long needle of rusted iron, was about to reach its zenith. The Archway would open soon.

Kruvan, Skarrow and the rest of their squad were dotted around the loading area, along with another two squads of Corsairs, some of whom were manning the gun emplacements at the rear of the yard. They had taken defensive positions near cover, as had the red-uniformed mortal infantry. If the Space Wolves had overrun the Red Corsairs on the other side of the Archway, the Corsairs on Kerresh were ready.

Up on the ridge, the ridge runner Kruvan had ridden in stood still, only partially unloaded. All activity ceased for these transitions, to seamlessly resume once the coast was clear.

‘This waiting bores me, Kruvan,’ said Skarrow. The two were both positioned by large plasteel containers loaded with non-volatile supplies, a short distance apart.

‘Then be bored no longer,’ said Kruvan. ‘It opens.’

Not all Archways could be seen through when open. Some manifested as walls of rippling energy, while the one before Kruvan allowed a view through to Hacasta – when it was open. Looking into the Archway from his position in cover, Kruvan saw the stone arch begin to glow on the inside, and the view of the other side of the loading area begin to mist over, as if white fog were filling the area immediately beneath the Archway. That whiteness had an inner luminescence, which reached a level of intense, bright light, only to fade back, revealing the dark outline of bulky figures, the same size and shape as the Corsairs on Kerresh.

‘Are they…?’ Skarrow muttered nearby, eager to know whether they were friend or foe. Kruvan’s finger rested on the trigger of his bolter, ready to fire.

Between the figures on the other side were dark lumps, taller even than the figures. Were they structures, or vehicles?

‘Cut the ropes!’ came a voice: hoarse, animalistic, echoing through the Archway, a whole world away.

‘Cut the what?’ said Skarrow, but Kruvan ignored him. He didn’t care what the voice said, only that it hadn’t been a Corsair’s voice.

‘Space Wolves!’ he shouted, raising his bolter to target one of the shadowy figures as they began to resolve, but his target was obscured by the great dark heaps collapsing into a tumble of bouncing, smaller shadows that rolled forwards, through the Archway and out into Kerresh in a cacophony of grinding and clashing metal.

Barrels. Burning barrels spilling a trail of liquid behind them, rolling out onto the surface of Kerresh. Dozens of barrels spewing oily black smoke.

Kruvan fired on the first barrel he saw, and it was torn to pieces before it got far, spilling its contents on the ground to burn harmlessly away. Others had opened fire now – a kill-box had been left around the Archway, and most of the barrels were destroyed without getting close to a Corsair or mortal. Smoking trickles of liquid began to pool on the ground and spread towards the Corsairs, but a little fire wouldn’t hurt Chaos Marines. Some of the mortals began to pull back as their boots caught fire, pulling on rebreathers to protect themselves against the spreading smoke, but were otherwise unharmed.

‘Nothing but smoke,’ said Skarrow, and Kruvan glanced across to realise he could no longer see the rest of his squad through the black clouds.

Then came a roar like Kruvan had never heard, a single word from many voices: ‘Holdja!’

For Anvindr, to step through the Archway to Kerresh was to step out of the drudgery of time and into the eternal now of battle that was the home and purpose of the Rout. Everything that had led him to this moment – the long march through the blizzards of Hacasta, the guerrilla attacks on the traitors at every waypoint or encampment on Hacasta – became distant, detached. The black smoke the Space Wolves had created by rolling dozens of burning barrels through the Archway clouded his vision, leaving him unable to see, unable to catch a scent of his pack or his enemies through the tarry acrid stench.

He was one of fourteen Space Wolves, one of the three packs that had set out across the snows of Hacasta, now one Space Wolf short having seen one of their number’s thread cut. They did not need to see or hear the others to act as they did, to run forwards to face unknown foes in the dark with lethal violence. This was who they were.

They were the Vlka Fenryka, and the thread of Anvindr’s own life was just one amongst many, intertwined into a greater wyrd that led back to Russ, to the time when the Emperor bestrode the universe and Anvindr’s ancestors fought in his long shadow to tame the universe itself.

Through the thick smoke he charged. Anvindr knew that in such low visibility he would not get the chance to use his bolter, so he wielded his chainsword, the blade silent so that he might hear his prey. He heard movement to his right and stopped running, swinging his chainsword around, squeezing the button on the hilt so the teeth began to turn. A Red Corsair emerged from the black smoke, raising his arm defensively. The chainsword had not fully powered up, and the teeth were moving slow enough that they caught on the vambrace of the Corsair as he defended himself, throwing out sparks as the chainsword ground against ceramite.

Even over the screech of his weapon Anvindr heard the sound of movement behind him. He stepped back and to the right, withdrawing his chainsword as he did. The Corsair who had been pushing back against the chainsword fell forwards as the resistance was taken away, rapidly regaining his footing but stepping between Anvindr and another Corsair who had been about to shoot him in the back.

Anvindr lunged, swiping around the chainsword to knock aside the second Corsair’s bolter. The chainsword caught the barrel of the bolter, doing no real damage but causing the shot fired to go wide. The black smoke was clearing now, and Anvindr could see their immediate surroundings: he was fighting the two Corsairs in the space between two transport containers, dirty great metal boxes that towered overhead. The bolt that missed Anvindr punched through the container wall behind him, exploding with a muffled whoomph somewhere inside. Beyond the container, the sound of Space Wolf fighting Red Corsair could be heard, gunfire and clashing metal.

In striking one Corsair’s weapon aside Anvindr had left himself open to attack from the other renegade, who kicked him hard in the torso. Anvindr’s power armour protected his body from the blow but the impact knocked him backwards, smacking into the wall of the container behind him. Already breached and weakened by bolter fire, the wall tore apart as Anvindr’s colossal mass crashed into it. He landed on his back, crushing crates loaded with medical supplies as he fell. He rolled sideways and up into a crouch, raising his chainsword to defend himself, but instead of pursuing him the two Corsairs had held their position, raising their bolters and opening fire.

As bolter fire exploded around him, Anvindr threw himself to the side, swiping his chainsword around to tear through the far wall of the container. He fell in that direction, rolling out into an open area where he found himself face-to-face with Gulbrandr, who fired over Anvindr’s shoulder at the two pursuing Corsairs, who disappeared back into cover.

The smoke was almost clear now, and Anvindr could see his wider surroundings. The Space Wolves were advancing through a transit area scattered with loading equipment and containers, exchanging fire with Red Corsairs and their mortal soldiers, both sides moving between cover. At the edge of the loading area a ridge loomed, a ridge runner currently docked in a station building with an unusual clock tower. From the top of the ridge to ground level ran a sloping track on which a large elevator platform could take cargo to and from the ridge to the loading area.

Anvindr instinctively considered the ridge station a target worth taking, but as the smoke cleared a more immediate problem presented itself: two heavy bolter emplacements at the far end of the loading area opened fire, heavy bolts ripping through the cargo containers and other cover.

‘Great Russ,’ said Gulbrandr, as they ducked behind the remains of the container Anvindr had smashed through. ‘No wonder these traitors were pulling back. They can drop hel on us from above now.’

‘Aye,’ said Anvindr. The emplacements were mounted high, firing down into the area in which the Space Wolves were corralled. ‘Though they have left their belly soft in doing so. Draw their fire, tell Hoenir to follow my lead. Then be ready to press the advantage, we’ll be swamped out there.’

‘What are you–’ said Gulbrandr, but as the nearest heavy bolter paused briefly to cool down Anvindr shoved him out of cover and back into the open. Gulbrandr uttered foul Fenrisian oaths as the heavy bolter opened fire and he ran towards more distant cover, where Anvindr could see the rest of his pack.

Anvindr charged back through the ruins of the container and out of the other side, using the distraction to head towards the heavy bolter. He zigzagged between containers and loaders, keeping out of sight, but as he got within fifty metres of the heavy bolter it swung towards him, opening fire.

His chainsword swinging on his belt, Anvindr threw himself forwards while still running, crouching like an animal to push ahead on all fours, ceramite-covered knuckles scraping against rockcrete as he did so.

The air over Anvindr was aflame with heavy bolter fire but none caught him as he scrabbled forwards – the heavy bolter was mounted too high to fire down at such a steep angle.

Red Corsairs opened fire with their own weapons as Anvindr ran into their defensive line, and he felt the explosion of a bolt against his pauldron nearly knock him off his feet, but he kept running. The base of the gun emplacement was surrounded by a red armoured barrier and Anvindr ran straight at it, grabbing the top of the barrier with both hands and hauling himself over the top to drop inside the cordon. Bolts exploded and las-shots scorched all around him as he scrabbled over the top, heavy boots finding brief purchase to boost himself over. The roar of the heavy bolter, firing just above him, was deafening.

Once inside the barrier, two Red Corsairs were immediately on him, attacking from both sides. Anvindr drew his chainsword, which roared into life as he swung it at one Red Corsair. Suppressing his rising kill-urge, he aimed his chainsword at the knee joint of the Space Marine’s power armour, dealing a glancing blow that brought the Corsair to his knees. Anvindr then swung the chainsword around to the other Corsair, who was coming for him with a combat knife. He let the Corsair come in close for a swipe with the knife, falling back and catching his enemy’s wrist momentarily. Allowing the chainsword in his other hand to idle, Anvindr pulled the Corsair close to him and brought its pommel down hard on his helmet. The Corsair staggered back, stunned.

With both Red Corsairs briefly downed, Anvindr climbed the base of the weapons emplacement, a metal pillar embedded in rockcrete and surrounded by sandbags. The barrel of the heavy bolter was white-hot overhead, but Anvindr ignored it in favour of swinging his chainsword around to cut through the mass of cables and lines that trailed down from the underside of the weapon.

Anvindr saw the weapon satisfactorily splutter to a halt before the Corsairs below dragged him down from the emplacement.

Curse these Space Wolves, thought Kruvan – they were hard to kill. The same old Space Wolf with the chainsword that had eluded Kruvan and Skarrow amongst the containers then dodged their fire once more to destroy the heavy bolter.

Now, though, the Red Corsairs had him. Half a dozen of their number had seized the beast and dragged him down from the gun emplacement, wrestling him out into the open. The Space Wolf’s helmless head was a mass of white-tinged hair and beard that shook as he cursed and struggled, a Corsair holding each limb and Skarrow’s arm locked around the old Space Wolf’s neck.

Kruvan was left free to finish the job, and raised his bolter. To kill a Space Wolf was a memorable moment, one he would recount for many years to come.

‘Just kill him, Kruvan,’ said Skarrow, as the beast roared and struggled.

‘What is your name, Space Wolf?’ asked Kruvan. ‘Tell me, so that I can at least tell stories of how you fought.’

The old Space Wolf stopped struggling then, as if broken. Pathetic animal, thought Kruvan; all it wants is its name scratched on the same cave wall as its ancestors. Having removed his damaged helmet, Kruvan kept his contempt off his face as best he could. He wanted that name, to complete the story of how he had hunted the Space Wolf.

‘They call me Old Nose-Breaker,’ said the Space Wolf, snarling through clenched fangs.

It was a name one would expect from a primitive, but it was a name, so there was no need to keep the Space Wolf alive. Kruvan’s finger tightened on the bolter’s trigger.

The hail of bolts that exploded around the Corsairs came from behind Kruvan, one detonating near his right foot while another exploded on his left pauldron, causing his shot to go wide. The Corsairs who were holding on to the Space Wolf let go, moving swiftly to open fire on their enemies, all except Skarrow, who tried to use the Space Wolf as a shield, arm locked around the Space Wolf’s neck. ‘Old Nose-Breaker’ roared, lifting Skarrow up and staggering backwards until the Corsair holding on to him slammed into the armoured barrier around the base of the gun emplacement. The Space Wolf jabbed both his elbows back into Skarrow, and the Red Corsair let go. Then the Space Wolf charged forwards, pushing Kruvan’s gun arm aside and bringing his forehead crashing forwards into Kruvan’s face.

Kruvan felt his nose break.

The rage took hold of Anvindr as he shoved the Red Corsair over with his full body weight, landing on top of him and letting his fists continue the work his headbutt had started, pounding the stunned and bloodied Corsair’s face with his knuckles.

Around him, battle was joined. Hoenir and Sindri were standing back to back, Hoenir’s power fist deflecting blows from Corsairs with such force they were thrown back with the impact, while Sindri’s chainblade sliced back and forth with a precision that contrasted with his high laughter. Tormodr was favouring his fists over his flamer, gauntleted hands rising and falling like pistons, smashing into skulls, while even Gulbrandr was engaging the enemy hand-to-hand, twisting necks and punching throats.

The Red Corsairs were being driven back, and the lines of battle were moving on, away from where Anvindr was beating on the fallen Corsair. Anvindr was dimly aware of this in his ferocity, part of him warning that he was toying with the Corsair as unwisely as the Corsair had toyed with Anvindr.

In his frenzy Anvindr did not listen to the voice of his better nature, and kept punching right until the cold blade sunk into his neck and he lost control of his limbs.

Kruvan’s face was a crushed mass of agony, and he had temporarily lost consciousness from the blows.

He was brought back to full awareness by a red-hot pain in his neck, a fire that burned through his nerve endings. His hearts hammered in his chest, and his eyes opened wide to see the Corpsemaster looking down at him with contempt.

‘Get up and run,’ said Garreon. ‘This site is lost. We will take the ridge runner to the factorum, return and drive the Space Wolves out. There is nothing to be gained by staying here now.’

His body flooded with adrenaline, Kruvan was on his feet. His hand went to his neck. ‘What did you give me?’ he demanded.

‘A stimulant of my own devising,’ said the Corpsemaster, a cruel smirk twitching at his mouth. ‘I am curious to see whether you survive the experience.’

‘And the Space Wolf?’ asked Kruvan.

The one who called himself ‘Old Nose-Breaker’ lay static on the ground, eyes wide and mouth twisted in a rictus of pain.

‘A nerve agent, also my own,’ said Garreon, already walking away. ‘Now come, we must withdraw.’

Kruvan considered putting a bolt in the old Space Wolf’s head before following Garreon, then decided that the Space Wolf looked in too much agony to allow him the release of a quick death.

Tormodr knew that he was not a rapid thinker, that he would never have the fast strategic instincts to lead a pack. He did not have the sharp mind of Gulbrandr or Sindri, able to quickly switch between many targets. Tormodr knew these were not his areas of expertise as a warrior, but he also knew they were not failings to be corrected. His way of waging war was different, but served the pack well. He was slow but relentless, grinding down the enemy with flamer and fists. He saw the long objective and how to steadily reach it, and sometimes he saw patterns in the flow of battle that other, quicker wits could not.

‘The traitors are retreating,’ he said, inbetween bursts of his flamer.

‘For a retreat,’ said Sindri through gritted fangs, ‘this feels remarkably like a spirited defence.’

The front line of the battle between the Corsairs and the Space Wolves had moved to the base of the ridge that ran past the Archway to Hacasta. The two forces were exchanging fire, the Space Wolves getting in close to engage in the close-quarters combat at which they excelled. Their numbers were equally matched, but the Red Corsairs had mortal support while the Space Wolves did not – no kaerls would have survived the long trek through Hacasta’s snowy wastes. While the traitor Guardsmen and other mortals supporting the Red Corsairs were little direct threat to the Space Wolves, they proved a disruption, hanging back and firing on the pack from afar. Buildings had attached themselves to the ridge up to the station, and mortal las-fire rained down from narrow windows above.

‘They are withdrawing,’ said Tormodr, setting the ground floor of a building ablaze with his flamer, roasting the mortals within. ‘They leave their mortals to fight for them.’

He did not expect Sindri to understand. The fair-haired Space Wolf was alive to every threat around him, chainsword whipping back and forth and bolt pistol barking, but as ever Sindri was focused on the immediate threat; he could not see the slower, bigger picture.

‘They withdraw towards the ridge, to that runner,’ grunted Tormodr, looking up.

‘Then we should take the fastest route to join them,’ said Sindri with a vulpine grin. He elbowed aside a mortal and charged past Tormodr, towards the elevator platform, which was already beginning to rise slowly from ground level. Tormodr followed.

The platform was loaded with cargo, half a dozen Red Corsairs firing defensively as it began to rise. Sindri was approaching the platform sideways, running the length of the ridge, and so he was hidden from view by barrels as he leapt onto the edge of the platform. He dropped to one knee, reaching an arm down to grab Tormodr’s hand.

‘I blame you entirely for this idea,’ said Sindri, straining as he pulled Tormodr up. Tormodr felt the toe of his boot catch the edge of the platform, and pushed himself the rest of the way. He did not reply beyond a grunt.

‘Your point is well made,’ said Sindri, responding to what he presumed Tormodr would have said. ‘But you inspired the idea, nonetheless.’

Tormodr remained silent.

‘Very well, I concede my failing and will endeavour to correct it,’ said Sindri, firing up his chainsword and drawing it back. ‘Now cease these relentless accusations.’

‘For Russ!’ shouted Sindri, his chainsword tearing through the barrels between him and the Red Corsairs on the platform.

Anvindr thought himself dead, to begin with. His eyes saw only darkness, he could hear nothing. His body would not move. He felt himself trapped in his own corpse.

No, he thought. In death there would be no pain, a carcass felt nothing. Whereas the rigor that gripped Anvindr came with a cold, heavy pain. Anvindr’s thread was not yet cut; he could dig himself out of this grave.

He started with his core, his hearts and lungs, focusing on drawing ragged breaths, concentrating on his heartbeats through the fog of pain. The more air in his lungs, the more blood pumped by his hearts, the quicker his enhanced body would fight off the poison in his system. His chest felt constricted, as if a tombstone lay upon him, but he forced it to expand and in doing so he became aware of further stabs of pain in his back and shoulder blades.

His senses were still lost to him, his extremities frozen, but his body was beginning to unlock, the cold heaviness replaced by a hotter pain spreading from his centre. He needed to move more, let that sharper pain course through him, burn out the foulness in his veins. He arched his shoulders, and felt something other than pain as his armoured elbows hit hard ground beneath. Hands and fingers still beyond his control, Anvindr forced himself up onto one elbow, then with a heave pushed himself over so that his face smacked into the ground, grit and dirt scratching against his cheek.

This was good; he was regaining feeling. His other senses were beginning to return: he could smell the blood of the Corsair he had headbutted, taste it at the back of his mouth. He could hear distant gunfire, and the sound of it gave him new purpose. His fingers were still not fully under his control but he shoved the heels of his palms down, levering himself up. He was Anvindr Godrichsson of the Vlka Fenryka, and there was a battle he needed to fight.

It seemed to take an age to raise himself to his knees, but when he did Anvindr found his vision clearing. It was like staring through a blizzard, a fuzz of white light with vague shapes visible, but Anvindr had fought his way through enough blizzards on Fenris. His muscles burned as he stood tall, and he nearly collapsed again as he leaned over to retrieve his chainsword with cold, clumsy fingers, but he was up and moving.

With deliberate, painful movements, Anvindr began to walk towards the sound of battle.

The Red Corsairs wore power armour that resembled a grotesque parody of an uncorrupted Space Marine, cracked and blackened and festooned with heretical symbols and trophies. Their very existence struck unease deep into Tormodr’s gut, and he unleashed a torrent of promethium across the elevator, setting it ablaze. The fire would not breach the enemy’s power armour, but it would give them pause as they opened fire on Tormodr and Sindri.

The two Space Wolves were at one corner of the elevator, while half a dozen Corsairs were spread across the rest, with now-burning crates and machinery inbetween them.

‘They think us cornered,’ said Sindri, rolling forwards to evade a burst of bolter fire, taking cover behind a flame-licked generator.

‘Then, by Russ, we shall show them it is unwise to try to trap a Space Wolf,’ bellowed Tormodr, charging forwards through a hail of bolts, running towards the Red Corsair nearest the edge of the elevator. A bolt exploded off Tormodr’s helmet, causing his vision to blur and crack, but he was too hard-headed to let that stop him, and he rammed straight into the Corsair, knocking him off the edge. The Corsair fell back to ground level with an outraged roar, and Tormodr dropped to his knees, pulling off his damaged helmet. He had already stowed his flamer, and he held a combat knife in his right hand.

Staying low, Tormodr ran to the ridge-side of the elevator, where two more Corsairs were firing on Sindri, who was in turn locking chainswords with another Corsair.

Tormodr shoulder-charged the first of the two Corsairs, who smashed into the second as he was tipped off balance. That second Corsair crashed through the safety railing and became wedged between the elevator and the ridge, the ceramite of his armour screeching against the side of the ridge as he tried to extricate himself.

As the first Corsair recovered his balance he turned his bolter on Tormodr, but the Space Wolf struck out with his left arm, knocking the barrel aside, metal clanging against ceramite. Holding the knife sideways in his right hand, he punched the Red Corsair hard in the helmet, three rapid blows that didn’t crack the armour but left the Corsair momentarily stunned. Then, when his enemy was off balance, Tormodr turned the blade around, forced the tip of the knife beneath the helmet of the Corsair and thrust forwards, pushing his whole body weight behind the knife. As the Corsair fell backwards Tormodr fell with him, using gravity to push the knife home, between thick layers of armour and through the thinner layer of material that joined them. As the Corsair crashed into the elevator floor, Tormodr landing on top of him, the impact pushed the knife right into the Corsair’s neck, a blow that reverberated back up Tormodr’s arm.

‘Skarrow!’ bellowed the second Corsair to his fallen brother, having pulled himself back onto the platform. He was about to shoot Tormodr in the head at short range, but was distracted by Sindri running across with a chainsword dripping with blood.

The elevator reached the platform level, and the Red Corsair jumped back from Sindri’s blow, into the ornate space of the ridge runner station. The Corsair opened fire, and was joined in supporting fire by other Corsairs as they saw the Space Wolves in their midst. The platform was hectic with activity as Corsairs and their mortal followers boarded a train that was already beginning to move.

Tormodr and Sindri ducked back into cover as bolts flew at them from half a dozen different Corsairs, detonating across the elevator as they hit crates and containers.

‘We are vastly outnumbered,’ said Sindri, sheathing his chainsword and cocking his bolter. ‘A whole train full of Traitor Marines. Impossible.’

Tormodr grunted as he took the bolter from the dead Corsair. It would do.

‘I know,’ said Sindri. ‘I couldn’t have said it better myself.’

Anvindr found the other Space Wolves at the base of the ridge, exchanging fire with unseen enemies in the station building atop the ridge, as well as within the structures that supported it. The ground around them was littered with bodies: some Red Corsairs, some Spaces Wolves, plus a large number of the Corsairs’ mortal followers, from uniformed officers to rag-wearing slaves. The Red Corsairs may have retreated to the ridge, but they had done so at a cost.

‘They flee from us like rodents,’ said young Hoenir as Anvindr approached. He bared his fangs in jubilation.

‘Why are we not chasing them down?’ Anvindr demanded. His voice came out weaker and more slurred than normal, the after-effect of the drug in his system.

‘The enemy collapsed stairwells as they retreated,’ said Gulbrandr, and Anvindr could tell from his cocked head that the other Space Wolf wanted to ask what had happened to him, but knew now was not the time. ‘Tormodr and Sindri stormed the elevator, but they are the only ones to find a route.’

The great ridge runner that was docked above could just be seen over the edge of the ridge, and was moving out of the station, travelling away from the Archway.

‘See?’ said Hoenir. ‘The traitors are in flight.’

As he spoke, the clock tower of the station exploded. It was a building of stone, and huge chunks of rock were propelled in all directions, causing the Space Wolves below to back away as debris fell to the ground. As the tower tilted to one side, falling through the structures that supported it, the explosions spread, ripping apart the station and everything the humans had built around the ridge. The initial blast of rock chunks from the explosion was followed by a great cloud of dust that spread outwards, blinding even the Space Wolves, a choking expanse of crushed debris that spread in all directions.

When the dust cleared, there was nothing but burning rubble at the base of the ridge, a cairn too great for even the Space Wolves to dig through, under which Sindri and Tormodr were lost.

Anvindr felt a pang he had not felt since the loss of Liulfr, in the cursed depths of Hrondir’s tomb. A howl rose in his chest, a feral scream of grief.

His brothers were gone, his brothers were gone.

Twenty

On the deck of the Fist, Valthex looked out at the Ironshore as Huron Blackheart’s galleons circled. It was an island, sheer walls surrounding it with only a strip of rocky beach between the wall and the sea. The wall towered over the galleons, and Valthex saw it not just with his eyes but with all the sensors and scanners at his disposal, looking for any potential weakness.

‘That is not iron,’ he concluded. From a distance the Ironshore looked exactly how it sounded, a surface of dull grey metal, but looking closer the material had a translucency akin to smoked glass, the granularity of rock…

‘What is it, then?’ demanded Huron Blackheart.

‘No material known to mortals,’ said Valthex. ‘Nor like anything I have witnessed in the warp.’

‘Uncertainties bore me,’ Blackheart spat. ‘What payload of explosives would bring such a wall down without damaging that which lies behind it?’

‘Difficult to say, my lord,’ replied Valthex, preparing himself for Huron to lash out at this unwelcome news. But the Tyrant was still, in thought.

‘I will not bury my prize in rubble,’ said Huron Blackheart. ‘Let the cannons lie still – we will take the Ironshore with fist and bolter.’

On board the Merciless Strike, Rotaka prepared for the landing ramp to drop and the taking of the Ironshore to begin.

This was as it should be, thought Rotaka as he checked over his bolter. In a universe with Space Marines in it, almost all conflicts came down not to artillery batteries or planet-cracking orbital weapons, but to individuals on the battlefield, the firing of bolters and the wielding of armoured fists.

The last conflict between living things, whenever it came to this benighted universe, would not be a detonation of some apocalyptic weapon that consumed the last scraps of living matter, but the physical struggle between the last two warriors standing. All weapons depleted, they would choke and claw each other to death at the end of everything.

At least, that was how Rotaka thought it would end.

For now, it made sense to him that the Ironshore would only be breached by the Red Corsairs themselves, either breaking it down by force or scaling it and cracking those defences open from the inside.

Of course, Rotaka thought as he watched the huge container he had been listening to in the depths of the ship be hauled out on to the deck, even once the galleons had landed the Red Corsairs would not be entirely without powerful support…

The Ironshore was quiet as the galleons crunched into the beach below, as it had been throughout their approach. Rotaka was under no illusions that this was anything other than a matter of the defenders waiting for them to get close before revealing their hand.

Then the ramp dropped, and Rotaka was a little behind the front line as they charged for the Ironshore, so he had a better angle to view the spheres that fell from the top of the wall. Grenades, set to explode on impact. As the first few hit, the line didn’t hesitate – the explosions had little effect on the Corsairs, and the mortals feared the presence of Huron amongst them, and the fatal discipline the Tyrant’s Claw would mete out, more than being torn to pieces by a grenade.

What Rotaka hadn’t expected was that the grenades would include a variety of explosive types. Some released bursts of deadly shrapnel, red-hot chunks of cruel metal that tore through exposed flesh and any armour weaker than the Red Corsairs’. Others exploded with an outward burst of corrosive acid, sizzling against flesh and armour alike. Others still exploded in a burst of poisonous gas.

Most of these were harmless to the Red Corsairs, but their cumulative effect was confusion, with burned, torn and otherwise wounded mortals reeling into each other. The first attempts to approach the wall with extendable siege towers had been thwarted, the towers either knocked sideways by the blasts or stopped in their tracks as their crews were destroyed.

In the middle of this pandemonium, Rotaka was tracking the top of the wall for any movement he could target with his bolter, but the defenders were too clever to be visible, launching a steady flow of grenades without sticking their heads out.

What did emerge from the parapet were the barrels of plasma cannons and heavy bolters, which began to spray both the foot-soldiers on the ground and the galleons they had emerged from with a wall of heavy fire.

Even slightly back from the base of the wall, Rotaka was looking up at a very steep angle, but he tried to find something bigger than the end of a gun barrel to target. His search for a live target was broken by a giant claw locking over his pauldron, and the voice of his master at his ear.

‘Rotaka,’ hissed Huron Blackheart. ‘It is time to wake Kolsh.’

‘It is quite a thing to watch the Adeptus Astartes fight each other,’ said Inquisitor Pranix, as the Space Wolves’ human servants – the kaerls, Cheng believed they were called – bustled around, maintaining communication between Pranix and the force led by the Wolf Lord Haakan. ‘It is an honour for mortals to see god-like beings clash, with all their might and martial prowess. Few eyes get to look upon such displays of battle.’

The inquisitor spoke while sitting in a corner of one of the Gatehouse’s drabber chambers, in which the kaerls had set up their communications. While the Iron Priests and their wards held off any scrapcode infection from the Space Wolves’ own communications, they had set up their command centre away from any of the Lastrati comms, just to be sure no cross infection was possible. Pranix had taken to sitting at the edge of the room on a chair he had looted from the servants’ quarters, rather than taking a visible position of command at the centre of the room.

Dumas Cheng, sitting on a more elegant chair nearby, resisted the urge to meekly nod along to Pranix’s monologue. As Cheng found himself further at the periphery of the decisions being made about the future of his worlds, the system under his governance, so a new frankness had emerged in his speech and manners, a refusal to bow and scrape to the lord inquisitor who had taken charge.

Irritatingly, Pranix’s dislike of social niceties and ceremonies meant that the more bluntly Cheng spoke to him, the more engaged Pranix was with the conversation.

If I shot the bastard and kicked him into a cesspit he’d probably take it as a compliment, thought Cheng.

‘If it is such a spectacle, lord inquisitor, then why deny yourself the chance to be there in person, instead of communicating from afar?’ Cheng asked.

‘Because it is an honour best given to those who wish such glory to be the last thing they see,’ said Pranix, unfazed by the implication of cowardice. ‘Besides, the Space Wolves want to run free unencumbered by those not of their pack. I have fought beside them before, but that was a different time and different circumstance. Wolf Lord Haakan is more than capable of leading in the field, so I will set the Space Wolves to running and see what they bring back.’

‘This opportunity has come at great cost, lord inquisitor,’ said Cheng, thinking of the ruins of the Onyx Palace. They had found what they had been looking for, but in the process destroyed millennia of the Hollow Worlds’ heritage, leaving the throne world permanently scarred. ‘I pray it is not in vain.’

‘If it is in vain, then the loss of one palace will be the least of our problems,’ said Pranix. ‘Do not dwell on the potential for failure, my Lord Cheng. You have offered us the chance for victory, and Lord Haakan is one of the greatest of his kind. He has led his Space Wolves to victory on a thousand battlefields.’

‘Let us hope this is the thousandth and first,’ said Cheng.

One of the kaerls, a white-haired man named Walder, stood to attention before Pranix. The kaerls of military rank wore simple but sharply pressed grey uniforms, and being of Fenris they were imposing figures in their own right.

‘Position attained and held, jarl,’ Walder told Pranix. ‘There is limited room on the other side, though, so the majority of Jarl Haakan’s force will be positioned on our side, to move in once engagement is made.’

Pranix nodded. ‘Please inform my Lord Haakan that I approve his strategy,’ he said.

Walder nodded sharply, and moved to return to his station.

‘Also, I am not a jarl, Walder,’ said Pranix before the kaerl departed. ‘I do not hold that honour. “Lord” or “inquisitor” or “that serpent” will do fine.’

‘My lord,’ said Walder, nodding again, a smirk visible. Cheng watched Pranix’s eyes track the kaerl back to his station, impassively.

‘They have no love for you,’ said Cheng. ‘Nor you them.’

Pranix ignored him.

‘Don’t you tire of the endless ritual and ceremony?’ Pranix asked. ‘The honorifics and the titles?’

Cheng was about to reply with an honest ‘no’ when a commotion could be heard from outside, a great rattling as if a whirlwind had entered the corridors of the Gatehouse.

Cheng, with the dignity that he had been taught came with his office, remained calm as kaerls and Gatehouse staff drew weapons and ran to secure the room, but Pranix was already on his feet, fists clenched, the whites of his eyes beginning to glow.

‘No, damn you, no,’ hissed Pranix, but the storm was upon them.

What came through the door was hard for Cheng to focus on in the few seconds he retained consciousness, a storm of wings and teeth surrounded in milky white lightning, coruscating tendrils of power that grabbed at Cheng, cutting into him, dozens of painful wounds opening in his flesh.

‘Witchcraft!’ shouted Walder over the howl of unnatural winds and the flapping of monstrous wings. He opened fire, as did others, but whatever it was it had no interest in the kaerls or guards, instead descending on Pranix, seizing hold of him, shrinking as if to squeeze inside him.

Then the storm slammed into Cheng again, cutting him once more with a flurry of invisible blades, and he lost consciousness as the storm disappeared back out into the Gatehouse, Pranix entwined at its core.

Amidst the furore of the attack on the Ironshore, one thing moved slowly and purposefully - the huge container being rolled out onto the beach, dragged by dozens of slaves, stoop-backed creatures with over-developed shoulders.

When the box – though box was an inadequate term for an ancient metal container humming with malice, bound with chains and covered in protective wards – came to a halt, Huron Blackheart was there, Rotaka at one shoulder and Anto at the other. Valthex stood nearby.

‘We could never disconnect the sarcophagus,’ said the Techmarine. ‘The sorcerers may have kept him from attaining full consciousness, but he has not truly rested since… the last time.’

There was a low thump from within the box.

‘So I hear,’ said Huron, with a dryness that almost reminded Rotaka of the old Huron, the Lufgt Huron who had inspired worlds as well as terrified them. ‘Break the wards, sorcerer.’

Anto raised his staff, and gabbled something in an unfamiliar tongue. Flames began to lick around the eye slits of Anto’s helmet, and energy crackled up the staff. As he spoke, the seals and symbols covering the crate burned away in wisps of acrid smoke. Locks on the chains binding the container sprung open of their own accord.

‘Be released,’ shouted Anto, slamming the base of his staff into the ground. ‘Be released and awaken, Kolsh of the Red Corsairs.’

With that, Anto slumped, smoke rising from his armour. The ritual was done.

Then, nothing happened. In spite of the sound of battle all around them, as the Red Corsairs tried to scale the Ironshore and the invisible defenders rained destruction from above, there was a strange pocket of silence around the great crate, a silence broken by Huron Blackheart himself.

‘Damn you, Kolsh,’ he bellowed, slamming his closed power fist into the side of the box. ‘Wake up.’

When the crate exploded, it did so with a roar louder even than that issued by Huron, a booming howl of rage and despair. As fragments of shredded metal fell all around, a towering monstrosity was revealed, standing in the ruins of the crate – a helbrute, plates of reddened, scarred armour linked by both ancient, oil-weeping machinery and warped flesh. One of its arms ended in a multi-melta, the other a taloned power fist, while an oversized helmet sat low on its shoulders, almost at chest level, its eye slits burning with unnatural light.

‘I hear you, Lufgt,’ said the helbrute. ‘Kolsh of the Astral Claws, angel of the seven emperors, scythe of the dragon sister, hears your command.’

Huron Blackheart tolerated neither use of his disavowed name, nor mention of the Astral Claws. By invoking both, and maintaining the delusion that those days had never ended, Kolsh was committing the most severe verbal treason. No Red Corsair, not Garreon nor Valthex nor any of the others, would be allowed to speak that way and live. But Kolsh would never understand that.

Long ago, before Rotaka had been elevated to the ranks of the Astral Claws, Kolsh had fought alongside Lufgt Huron. He had fallen in battle, his damaged body entombed inside the colossal machine that stood before Rotaka now. Rotaka remembered him from those days: imposing, noble, terrifying.

Then the Badab War had begun, and the Astral Claws had found themselves fighting against the Imperium they had once served. Most remained loyal to Lufgt Huron, now Chapter Master and Tyrant of Badab. A few had rebelled against their leader, and were either rapidly purged or fled the system to beg for mercy from the loyalist forces.

Kolsh had taken neither path. Instead he had gone insane, his mind broken by the horror of divided loyalties. He had followed orders to the last, and continued to do so when Huron required his services, but his perception of reality was distorted beyond all recognition. He still fought, but as he did so he was not combating the enemy he actually faced, but imaginary foes his shattered mind could cope with. Kolsh’s reality was one of battles no one around him could comprehend, against foes drawn from his imagination.

As an ally, Kolsh was a tremendous asset, but like all helbrutes more dangerous than the enemies the Red Corsairs faced, should rage overcome him.

‘Well?’ asked Kolsh, kicking aside the remains of the armoured container he had rested within for many years. Every step could be felt through Rotaka’s body like an earthquake. ‘What is your order?’

The question was laden with threat. It was Kolsh’s unique madness that kept him from succumbing to the murderous fury that consumed other helbrutes, but he was not immune to it. He needed direction, and quickly.

‘We must take the wall, Kolsh,’ said Rotaka.

‘Take the wall?’ bellowed Kolsh, turning on Rotaka, the power claw flexing over his head. Rotaka was aware the helbrute could decapitate him with a pinch of those talons. ‘How can we trust we are even outside the wall when the below is up above?’

The skies of Kerresh had cleared, and the seas were clearly visible behind the sun above them.

‘Noble Kolsh,’ said Huron, his voice taking a tone Rotaka had not heard in years. It was the voice of Lufgt Huron. ‘These illusions are simply xenos tricks. They send their lies from behind this barrier.’

Huron’s voice was unusually free of anger, but Rotaka could see that the Tyrant’s Claw was clenched in controlled rage behind his back.

‘Very well, son of light,’ boomed Kolsh. ‘I will conquer the barriers behind which this alien filth cowers.’

Without further word the helbrute was moving, and Rotaka and the others had to swerve aside as the giant crashed past them, crushing mortal soldiers beneath his metallic tread, charging straight at the wall.

As Kolsh approached the wall, the helbrute mounted a fallen siege tower, the frame of the tower creaking as his enormous weight crunched up its length to reach a point halfway up the wall. Reaching the end of the tower, he swung back the power fist and brought it crashing back. The arm came down, and where it hit the wall it dug deep into the sheer surface, the barb lodging firmly.

‘To the parapet, my brothers,’ said Kolsh, bracing his huge legs against the wall, pushing upwards and bringing the other arm down to lodge higher up.

Then he pulled the first limb free, and repeated the process, piercing the wall a little higher.

Rotaka realised he was watching a helbrute climb.

From above, the fire and grenades began to concentrate on Kolsh as he climbed, but he was utterly unscathed by the attacks.

As the defenders of the Ironshore desperately tried to fire on Kolsh, only able to use hand-held weapons at such a steep angle, they leaned over the parapet to do so, at last exposing themselves. Rotaka found a target and fired, the first loyalist body dropping from the Ironshore to cheers from below.

Within seconds, the weapons on the decks of the galleons were bombarding the parapets, obliterating anyone else who exposed their position.

Beneath Kolsh, shielded by his huge bulk, Red Corsairs were beginning to climb where he had gouged handholes into the wall. Siege towers were being righted, reinforcements flowing up the beach. Grapple launchers were fired, the hooks beginning to find purchase now.

The scaling of the wall began in earnest, with Kolsh in the lead. Rotaka shouted to his squad to follow and ran to catch up.

‘Great Russ, what I would not give for a Rhino right now,’ said Hoenir, wrestling with the steering controls of the mortal vehicle they had commandeered. ‘This thing handles like a wild beast.’

After a pause Gulbrandr responded. ‘Then you should concentrate on taming it,’ he replied. ‘And silence your complaints.’

Anvindr listened, but remained silent. He could not bring himself to speak. Sat in the open-topped back of the halftrack vehicle, his bolter on his lap, he looked out across the blasted landscape of Kerresh as the vehicle bumped and swerved on the pitted road running alongside the ridge. Their mission was to scout ahead, to locate where the Corsairs had withdrawn to in their ridge runner, presuming that they weren’t half a world away already.

All they had seen so far was death and destruction, evidence of the Corsairs’ influence. The smoking buildings and unburied corpses were an affront to his fresh grief.

They drove for another hour before anyone spoke again.

‘Here they are, damn them,’ said Gulbrandr, and Anvindr turned to see what his brother was talking about. Hoenir brought them to a halt.

Ahead was a factorum, built close to the ridge, and atop that ridge they could just see the Corsairs’ ridge runner halted at a station similar to the one they had recently found destroyed. The factorum was dominated by a central tower, and a huge, ragged banner hung down the centre, the aquila still visible beneath a crudely painted red saltire, the mark of the Red Corsairs. Anvindr made a low snarl at the sight of such desecration.

‘Should we report back now?’ asked Hoenir.

‘Not yet,’ said Anvindr. ‘I want to know their numbers.’

He stood up in the back of the halftrack, the vehicle creaking as he shifted in his armoured weight. A short distance away he could see a taller tower amongst the ruins.

‘There,’ he said. ‘That should give us the vantage we need.’

They went on foot, running across the ruins, beams and bricks crunching beneath their boots. The stench was terrible to Anvindr’s sensitive sense of smell – bodies were buried somewhere under the wreckage.

They climbed the tower, the purpose of which seemed lost to time. It was only six storeys tall, but it gave them a view of the factorum and the surrounding area. Around the factorum was a small town, crude workers’ habs, and even from a distance heretical markings were clearly visible on buildings and banners. Anvindr watched the mortals walk their streets, and could see the same manic gait in their movements that he had seen in the corrupted mortals elsewhere in the Hollow Worlds, the signs of minds twisted by the influence of Chaos.

Was this what the Corsairs had brought to all the worlds they occupied? Relentless corruption and creeping treachery? The Space Wolves had thought to inspire resistance from loyal subjects of the Emperor on Kerresh, to begin a process of liberating these worlds from the traitors, but if what Anvindr saw was typical, there might be little of these occupied worlds worth saving. Instead, a great scourging would be required once the traitors were driven out, to remove every last shred of their influence.

Grim work, but the Space Wolves would not shrink from it. As many cords would be cut as needed to drive witchcraft from these worlds.

‘Hear that?’ said Gulbrandr, tilting his head. Anvindr concentrated, and could hear it too – a low mechanical rumbling, coming from the direction of the factorum.

‘Let’s see what new toys these traitors have been manufacturing,’ said Anvindr.

‘There,’ said Gulbrandr, pointing towards the base of the factorum’s central tower. Even from a distance he could see the huge double door two-thirds of the height of the factorum itself. He could see many tiny figures milling around the doors, both mortals and the larger shapes of the Red Corsairs.

Hoenir’s shoulders were tense, his body leant forwards as if preparing to sprint straight towards the Corsairs. Anvindr understood his youthful eagerness, his bitter rage. Hoenir had not fought alongside Tormodr and Sindri as long as Anvindr had, but they had still been of the same pack for many years. He too sought blood vengeance, or at least to subsume his sorrows beneath the kill-urge.

‘Hold, Hoenir,’ ordered Anvindr. ‘Something comes.’

Witnessed by the Red Corsairs and the concealed Space Wolves, the factorum’s latest creation rolled out of the door. The traitors cheered as it came into view, their guttural glee echoing across to the tower where the Space Wolves were concealed.

Anvindr did not cheer. He could see immediately the Corsairs’ intent.

‘Vox the Archway,’ he told Gulbrandr. ‘Tell them the traitors are returning.’

Twenty-One

On Karstveil, Lieutenant Nistal knew well that the Lastrati were best experienced to defend the Ironshore’s single, impenetrable wall. The Lastrati had been preparing to defend the Ironshore for centuries, each generation training the next, and so the Cadians had left them to it, nimbly climbing the scaffolding against the wall, patrolling its ramparts and looking out to sea.

Nistal’s men were there in case the first line of defence failed, in the event that the enemy traversed the wall.

The area between the base of the mountain at the island’s centre and the wall of the Ironshore was a band a mile thick filled with low, fortified buildings, barracks, rough farmland, and even some patches of bleak woodland. Nistal didn’t have to worry about that entire area though, as there was only one target the enemy could be interested in on Ironshore.

The door was embedded under a stone archway in the mountainside. It seemed to be made of the same iron-like but weirdly translucent material that the Ironshore wall was made of, but instead of being a solid single piece it was made from criss-crossed beams sealed at the centre by a great wheel. The wheel was wider than Nistal and its centre was at human head height, but the spokes that protruded from it did not look shaped for the grip of a human hand. The door itself was five times Nistal’s height and he didn’t like to look at it. He didn’t know what was behind the door and he didn’t want to, but he knew that it was the Cadians’ job to defend it.

The first line of defence after the Ironshore’s sea wall consisted of three- and four-storey fort-like buildings linked to the scaffolding of the outer wall by bridges and ladders. Each had Cadians manning weapon emplacements on the rooftops, along with sharpshooters at the narrow windows. Between those buildings and the door were bunkers, barracks and warehouses, all barricaded with Cadians, the pathways between them sandbagged to slow the invaders as much as possible.

Nistal had placed himself with the very last line of defence, almost under the shadow of the arch, immediately in front of the great door. From there, he had line of sight over all the defences using magnoculars, and he could see the top of the Ironshore itself.

A short time ago the Lastrati had begun running back and forth firing on something below, on the other side of the wall. The attack had begun, Nistal watching from afar through his magnoculars. Even with that magnification the defenders looked tiny.

When they failed, when the defences were breached, it was not a gradual erosion, but spectacular and horrific.

The first thing to come over the wall was far taller than a man, and Nistal could make out a great bladed claw that swept out in precise, ferocious movements, Lastrati falling wherever it moved. The light caught a halo over its head as the creature moved with terrible speed, cutting the wall’s defenders to pieces.

The thing that followed was worse – a monster, a huge mechanical beast that dragged itself over the lip of the wall, knocking aside the Lastrati defenders and unleashing its terrible firepower both across the length of the wall and down into the area within.

‘God-Emperor,’ said Nistal. ‘What are we facing?’

As more traitors climbed the wall, the Cadians on the fortifications nearest the wall began to open fire.

The battle had truly begun.

Rotaka and his squad reached the top of the wall to find Huron Blackheart and Kolsh wreaking destruction, and the defenders of the Ironshore returning it in kind. Rotaka raised his bolter and returned fire as Lastrati troops shot at him with lasguns, and one fell screaming to his death on the beach below.

‘Ah, Lufgt, does this not remind you of the time we invaded the dream castles of Nyalhotep?’ said Kolsh, his multi-melta white hot, his power fist swinging back and forth.

Huron ignored the helbrute.

‘Red Corsairs, press forwards,’ barked the Tyrant. ‘The wall is taken, we move to the mountain.’

‘To the mountain,’ said Kolsh, stepping off the wall onto the mortal-built structure on the inside. It immediately began to collapse under his weight, and Kolsh lashed out, screaming and raging at imaginary enemies, knocking out supports and causing further damage.

On the roof of the nearest building mortals, were firing a heavy bolter on Rotaka’s position. Firing back, he jumped onto the scaffolding as it fell away from the sea wall, opening fire with his bolter as the boards beneath his feet shifted towards his target. Rotaka jumped off the scaffolding as it smashed into the building, landing on the rooftop and gunning down the troops manning the heavy bolter. On nearby rooftops similar emplacements were firing up at the Red Corsairs as they spread across the top of the wall, so Rotaka took hold of the heavy bolter and swung it around, unleashing a stream of bolts at the nearest targets, tearing them to pieces.

As Rotaka fired the heavy bolter, the rest of his squad reached the rooftop: Hulpin, Verbin, Wuhrsk and finally Malinko, limping slightly.

The entire building began to shake, causing Rotaka to fire wide with heavy bolter, missing his target and shooting into the outer wall.

‘What was that?’ asked Rotaka. ‘Demolition charges?’

Hulpin looked over the edge of the rooftop. ‘Near enough. Blessed Kolsh is fighting his way into the ground floor,’ he said.

The building shook again.

‘How can he be blessed?’ snapped Wuhrsk. ‘He thinks we’re part of the Imperium.’

‘That confusion is a sign of the gods’ blessing,’ said Hulpin.

The entire rooftop began to tilt sideways as further blows shook the building.

‘That confusion will bury us,’ said Rotaka. ‘We need to get to ground level.’

He abandoned the heavy bolter and ran off the roof, dropping to the ground below. He landed among mortal soldiers, and as their guns turned on him he lashed out, one fist knocking a Guardsman’s head back with neck-snapping force. With his other hand he drew his dagger and lashed out in a wide arc, the blade tearing through the body armour and flesh of two more Guardsmen.

Rotaka recognised the uniforms – Cadians, efficient fighters by mortal standards. As the rest of his squad dropped to the muddy ground the Cadians were pulling back smoothly, concentrating their fire on key points on the Corsairs armour and finding cover behind metallic barricades and piles of sandbags. Further blasts of las-fire and volleys of bolts were coming from firing slots in bunkers ahead of them, and Rotaka and his squad found themselves being pushed back towards the collapsing building by sheer force of firepower.

Then Huron Blackheart was among the Cadians, crashing through a barricade and swiping two of them aside with the Tyrant’s Claw, then bisecting another with a swing of his axe. He was close to one of the bunkers embedded in the ground, and turned the palm of the Tyrant’s Claw towards the narrow firing slit, spewing burning promethium through the gap to burn the Cadians within to ashes.

‘For Huron!’ bellowed Rotaka and his squad pushed forwards on the heels of their lord, bolters finding targets and bringing them down.

As they reached the Tyrant, Rotaka realised that Huron’s attention was partially elsewhere, engaged with someone other than them. Rotaka thought him lost in the grip of one of his delusions until the Tyrant addressed the voice he was hearing by name, proving it the product of a private vox-channel rather than his diseased mind.

‘Garreon,’ Huron snarled. ‘Get those dogs off my planet.’ He paused, as presumably the Corpsemaster offered some explanation as to how he would correct his error.

‘Then do it,’ snapped Huron. ‘Push them beyond the arch, but offer minimal pursuit. Hold that line until I say otherwise.’ Another pause. ‘Do not question me, Garreon, just act.’

Rotaka expected Huron to lash out in rage after such a conversation, and he and the other Corsairs had discreetly moved away from the Tyrant as he spoke to Garreon.

Instead, Huron simply turned to his next set of orders, pointing ahead through lines of Cadian defences to the mountain at the centre of the island. ‘To the mountain,’ he snarled. ‘Let no mortal stand against us and live.’

As Huron spoke, for the briefest second, Rotaka saw the constant rain pass through Huron rather than splash off his body and armour.

Then the next assault on the Cadians began and Rotaka dismissed what he had seen as a trick of the light from the pale, artificial sun above their heads.

On the Hacastan side of the Archway between that world and Kerresh, endless snow fell down on a long-toothed Scout by the name of Agmund.

Agmund kept watch, as he had done since the Space Wolves seized control of the area on the other side of the Archway. He stood by a rock, a supporting pillar from some fallen building, carefully sharpening the blade of his sword against the rock’s surface.

There were others of his kind scattered around the Archway, old Space Wolves who preferred their own company, content to leave the glory of finishing off the traitors to the Blood Claws and willing to take on the necessary, solitary duties. They signalled each other at regular intervals to state that all was well, low whistles issued through heavy jaws, but otherwise had no contact unless required.

Agmund preferred the company of the snow and the wind, and had no desire for the camaraderie of his fellow Space Wolves. Leave that to the young.

He paused, sword held slightly aloft. He heard something in the wind, and his nose wrinkled. There was a familiar, musky scent, a fellow Space Wolf, but that could mean anything. The enemy would not be above stripping the pelts from a fallen Space Wolf’s armour to conceal their approach from heightened olfactory senses.

A heavy tread grew closer, ponderous and leaden, heavy even for a Space Marine. It sounded nothing like the cautious walk of an enemy, but still Agmund whistled the signal to be alert, that someone approached.

‘No need for that, brother,’ said a deep augmented voice, which Agmund recognised.

‘Folkvar?’ he called out into the blizzard. ‘We thought you half a world away.’

The last Agmund had heard, virtually all under Folkvar’s command had been lost in battle with the traitors.

‘I was,’ said Folkvar. He had a mortal alongside him, wrapped in thick layers of clothing, so that Agmund couldn’t tell if it was even male or female. ‘But I heard the action was here, so here we came.’

‘You walked?’ said Agmund, and his grip tightened on his sword, regardless of how long he had known Folkvar. To travel so far unaided – was this witchcraft, some enemy trap?

Folkvar chuckled humourlessly, a grating sound through his augmetics.

‘Not quite, old Agmund,’ said Folkvar. ‘We requisitioned whatever vehicles we could find, took some of the monks’ shortcuts. The last one broke an hour or so back. I am not used to travelling in such flimsy vehicles…’

Folkvar trailed off and there was a weariness to his voice that Agmund had heard many times before. The loss of the Frost, the other tanks and crews under his command. Agmund had heard that tone in his own voice, when packs he had fought with had fallen. Folkvar needed purpose now, more than anything.

Agmund sheathed his sword.

‘Come,’ said Agmund. ‘Pass through the Archway. There is much to be done.’

On Karstveil, Hulpin followed Huron Blackheart and Rotaka into battle, but it was not their leadership that drove him on, chainfists swinging back and forth as he cut through the Cadian loyalists. It was his own faith, his belief that his gods looked approvingly on his actions, that inspired him.

The Red Corsairs had advanced halfway between the wall of the Ironshore and the doorway in the mountain ahead, behind which lay some resource pivotal to the Tyrant’s plans. The details were irrelevant to Hulpin; all that mattered was that Huron Blackheart was greatly favoured by the gods, and that to follow him was to do great work in their honour.

As the helbrute Kolsh pounded a bunker to pieces, smashing through the rockcrete roof and opening fire on mortals within, Hulpin followed Verbin as the other Red Corsairs charged through a barricade, dropping into a dugout on the other side. A dozen guns were on them instantly as Cadians charged from all sides, assailing the enemies in their midst, but Hulpin and Verbin lashed out in the close confines, pushing through las-fire that scorched their armour to break bones and tear flesh. Bolts exploded in the bodies of the mortals nearby as Rotaka, Malinko and Wuhrsk fired down into the trench.

This was worship, this was ritual, sacred carnage. Hulpin broke the bones of the dead and dying as he stepped on fallen mortals, striding to the other side of the dugout and climbing out to be greeted with the sight of his fellow Red Corsairs exchanging fire with the defenders of the Ironshore. A grenade exploded nearby, throwing up hot dirt into air already polluted by smoke and a mist of human blood. The air was thick with death.

As Hulpin dived into the fray once more, he felt that he was truly blessed.

Nistal fired his lasrifle until the barrel was hot in his gloved palm, until his wrists ached. The mile between the mountain at Nistal’s back and the Ironshore wall was a scene of carnage, and he had no shortage of targets to aim at from his position behind the last line of defensive barricades. There had to be over fifty Traitor Marines in the field, butchering Cadians and Lastrati alike, bolters and other weapons blazing, armoured fists lashing out at any mortal that came near them. In their wake came even more support troops, including red-uniformed traitor infantry as well as ragged slaves and barely human, mutated grotesques.

While some core part of Nistal was struck with fear by the horrifying sight of the traitors and their followers, he was still a Cadian born in the gaze of the Eye of Terror, and he kept firing and issuing orders even as it became clear that the defence was doomed to fail.

From his position at the last line of defence he could see the enemy beast machine kicking aside barricades, the human soldiers behind them knocked aside like dolls.

‘All heavy weapons teams, target that abomination,’ he shouted over the roar of gunfire. A mortar nearby fired, its explosive payload streaking up through the air to land on the metal monstrosity. The beast staggered as the explosion hit, but did not falter.

‘Again!’ shouted Nistal, his own lasrifle laying down suppressing fire to keep back the assailants now heading towards the mortar’s position. Two mortals, one stricken with a scaly left arm that made Nistal nauseous, fell to his shots, only for a towering figure to charge through las-fire and bolts alike, swiping aside any obstruction with a great clawed power fist which then spat promethium at the mortar team, burning them alive.

The fist, the dead, grey flesh, the halo of gold – Nistal recognised Huron Blackheart from his description, but nothing had truly prepared him for the Tyrant’s presence. He towered over even the other Red Corsairs and though he looked exposed, his face and head unarmoured to reveal patches of necrotic-looking flesh inbetween the extensive augmetics, he charged through his enemies unscathed, his power claw tearing through Cadians with dozens of kills to their name, decapitating or disembowelling them in an instant. He moved with terrible speed and fury.

‘No,’ said Nistal, mainly to himself. If they won no other victory, they would see Huron Blackheart bleed.

A grenade had taken out another heavy weapons team to the left of Nistal’s position, away from Huron Blackheart. From twenty feet away, the rocket launcher looked undamaged.

‘Murso,’ Nistal said to the sergeant next to him. ‘You have command.’

Before Murso could protest, Nistal was over the sandbags and running across open ground, bolts and las-fire flying past him. Skidding in the mud, he lay low next to scorched bodies as the air above his head was criss-crossed by enemy fire, his gloved fingers working quickly on the rocket launcher. It was ready to fire.

Kneeling up, mud soaking his uniform, he lifted the launcher on to his shoulder, aimed at Huron Blackheart and fired. He wasn’t wearing the correct shoulder pads or mount to fire the launcher, and as it kicked back it knocked him over and ripped through the shoulder of his coat, gouging into his flesh. As he fell, he watched the rocket streak across the space between him and the Tyrant, who was turning in Nistal’s direction.

Huron Blackheart batted the rocket out of the air, somehow hitting its side without striking the nose cone and detonating it. The rocket careened sideways, exploding against the barricade behind which lay the door in the mountainside, the barricade where Nistal had so recently been positioned.

And then the Tyrant was crossing the churned battlefield towards him, and Nistal scooped up a lasrifle and squeezed the trigger and…

Nothing.

Nistal’s muscles failed him. He couldn’t move his finger. Cold talons had sunk through his arm and shoulder, cutting tendons and leaving them limp, and Nistal could feel the weight of some unseen, heretical creature on his back, and its presence paralysed him, not with terror but by its cold presence freezing his body, and he could smell its foul breath as it blew past his cheek and…

…the creature was gone, but Huron Blackheart’s power claw was coming up, lifting him off his feet.

And he was dangling, feet off the ground, in agony, gazing into the face of Huron Blackheart, the dead, slack leer of pleasure, the sole surviving eye twitching with insanity. Over Huron Blackheart’s shoulder Nistal could see Murso and the others vaulting the shattered barricades, coming to his rescue only to be gunned down themselves, the forces of heresy closing in on the Cadians’ last stand.

With relief, Lieutenant Nistal died before he had to endure seeing any more.

Rotaka and his squad gunned down the last of the Cadians beneath the arch in the mountainside, moving in on them firing tight bursts of bolts. Behind them could be seen a towering door made of the same metal as the Ironshore seawall.

Rotaka turned to see Huron slide a dead Cadian off the Tyrant’s Claw and drop the corpse to the ground, with the casual disdain of someone discarding a dirty glove.

In the heat of battle, Huron Blackheart’s presence seemed to have solidified once more, as if violence itself kept him anchored in the universe. Rotaka and the others stepped back as the Tyrant walked towards his prize.

He gripped the wheel at the centre of the door with both hands, the Tyrant’s Claw fitting uneasily around the spokes. It did not move.

‘What is the password?’ said a voice.

Huron Blackheart stepped back from the door. The voice seemed to come from the very fabric of the door itself.

‘Poisoned chalice,’ said the Tyrant, repeating the phrase Rotaka had relayed to him.

The wheel in the door began to slowly rotate of its own accord, and the criss-crossed slats of the door separated and retracted into the wall. Behind it was revealed a corridor disappearing deep into the mountain.

‘Rotaka,’ said Huron, with a cold rage reflecting his indignation at having to ask for admittance to anywhere. ‘Deal with this creature as you dealt with its sibling.’

‘My lord commands,’ said Rotaka, bowing his head slightly. Then he led his squad into the mountain.

‘You know what’s in there,’ Rotaka said. ‘You know what we have to do.’

His squad exchanged nods and moved quickly down the tunnel. After the first turn it opened into a stone chamber containing a creature almost identical to the passenger they had received the code from, the corpulent once-human they had encountered on the never-stopping train. It was surrounded by similar life support systems to its sibling, and behind it could be seen another stretch of tunnel, from which came light of a kind Rotaka could not identify.

‘Welcome, traitors,’ said the gateholder, its modulated voice as self-satisfied as that of the passenger.

‘I refuse,’ snapped Rotaka, ‘to have this conversation again.’

Then the entire squad opened fire, bolters blazing, the explosive bolts tearing chunks in the gateholder’s body and life support, while Malinko’s flamer set the creature alight in a mass of blazing fat.

The gateholder slumped dead.

‘That was satisfying,’ said Malinko, to grunts of approval from the rest of the squad.

Rotaka opened a vox-channel.

‘My lord,’ he told Huron Blackheart. ‘The path is clear. The Orrery awaits you.’

Twenty-Two

‘In the name of…’ exclaimed Rotaka, then trailed off, unable to think of a suitable name to utter. Once, it would have been the Emperor, latterly the name of Huron himself. Now, he didn’t have any higher power to call on in the face of the inexplicable.

The Orrery was exactly what the name implied.

The Orrery was nothing like what Rotaka had expected.

It was an orrery in the strictest sense, a working representation of the Hollow Worlds, but it was neither a physical model with metal spheres moving on some visible mechanism, nor a hololithic display with the worlds projected in light.

No, this was something else. The cavern within the mountain was a vast space with a curved ceiling high above, and beneath that ceiling floated the Orrery, a planetary system in miniature. It was unclear how it remained suspended in the air, but it was fed with energy from a central pit in the chamber, in which a glowing mass of energy swirled. Periodically, bolts of fierce, wild energy would crackle between the pit below and the spheres above.

This was no projection. The spheres appeared to be made of stone and some translucent material, so that the interior of each world with its small sun was visible from outside, and Rotaka could recognise the continents of the worlds he had already visited. The model of each of these suns flickered with flame, a fiery imitation of its larger equivalent.

The smallest of the spheres was larger than Kolsh, and they floated in a cloud of shimmering particles, clearly representing the Siren Clouds. Between the worlds ran strands of coruscating energy, linking sun to sun and Archway to Archway, all feeding from an ice-blue sphere in the centre.

The spheres were moving, too, and while the ice-blue sphere remained at the centre of the system the rest of the Hollow Worlds did not orbit it in any conventional sense; instead the push and pull of the different energy streams caused them to weave around each other, the threads of power that bound them stretching as planets passed each other within the clouds.

Within this system, the positioning of the planets bore little resemblance to the interlocking of the Archways. Yes, Laghast and Plini were at one edge of the Siren Clouds, and Trincul at the other, but between them planets physically close in the rotation were completely disconnected, while others had Archways stretching between them even though they were far apart.

It was a machine, or a mechanism, Rotaka realised. Not just the Orrery, but the actual Hollow Worlds it imitated. An artificially created mechanism of unreadable purpose, one that might only pass for a planetary system because of its scale, and the life supported within it.

Rotaka had seen many things unimaginable to mortals, but the alien complexity of this confounded even him.

To Huron Blackheart, it seemed to be exactly what he expected. The Tyrant had barely looked up as they entered the presence of the Orrery, as if its presence were unremarkable. Whatever voices, whatever gods had whispered in Huron’s ear, they had kept him well informed.

The chamber was silent, as if no one had entered there in centuries. As the battle outside had faded, the last resistance crushed, Huron’s most trusted officers and counsel had joined them: Taemar, Valthex and Anto.

‘Exultance…’ breathed the Tyrant, breaking the silence.

Rotaka saw his master was gazing at the central sphere.

‘Anto,’ said Huron. ‘Can you divine a route?’ The Tyrant pointed his power claw upwards, towards the spheres.

It had not occurred to Rotaka that the Orrery could be scaled, but looking up he could see smaller, duller objects floating amongst the spheres. Were they viewing platforms of some kind, or control mechanisms? The energies connecting the spheres crackled across these duller objects, licking their surfaces, with an intensity that suggested they would cut through any weaker substance, perhaps even power armour.

Anto was shaking his head, and Rotaka saw a reticence in the sorcerer he had never witnessed before.

‘Whatever this is, it is no sorcery I have knowledge of,’ he replied.

‘Useless,’ snapped Huron. ‘Valthex, serve me better.’

The Techmarine stepped forwards, studying the Orrery intently. ‘There seems to be an access route there, my lord,’ he said, pointing.

Where Valthex indicated, Rotaka could see that there were protrusions from the walls, possibly control galleries, and they had been crudely linked by ladders, stairs and scaffolding constructed on a more human scale.

‘Beyond that, manual manipulation of the Orrery would seem to be necessary,’ said Valthex. ‘All energies on all spectra are concentrated within the Orrery itself. There is nothing else in this chamber that could operate it.’

‘There is something here though,’ said Anto, moving his staff as if to scan the walls. ‘A presence…’

Part of the far wall exploded, and a torrent of raging Space Wolves poured out into the chamber, bolters blazing.

Anto, thought Rotaka as he screamed an order to attack, you’re a genius.

The communications room on Ressial had been repaired as well as possible since Pranix’s kidnap, and there had been no further disturbances. Whatever terrible forces had swept through to abduct the inquisitor, they had shown no interest in anyone or anything else in the Gatehouse.

After such an attack, the silence seemed almost unnerving. Wounds had been tended to by the medicae, order had been restored, but the absence of Pranix was felt.

To his surprise, with the inquisitor gone and Haakan in the field, Dumas Cheng found eyes turning to him for leadership.

Damn you, Pranix, he thought. Damn you for undermining my authority here, then getting yourself swept away or killed and leaving to try to reassert it in the middle of a war.

Not that there were many decisions to be made. Cheng had told Pranix the myth of the Lost Archway beneath the Onyx Palace, the secret route to the Orrery, and the inquisitor had seized that faint hope like a starving hound with a hunk of meat. Even Cheng had been surprised that, following the demolition of large chunks of the Onyx Palace, the myth had proven to be entirely true.

A miniature Archway, leading to a cramped corridor approaching a hidden wall adjacent to the Orrery, one where the activities within that chamber could be secretly observed.

Why had it been constructed? To covertly monitor the use of the Orrery, millennia ago? As an emergency exit? It was impossible to tell, but its presence now was fortuitous.

Cheng had sat, completely still, listening to vox reports as Haakan’s force watched Huron Blackheart and a small force entering the Orrery. Blackheart had kept his entourage small, perhaps to prevent any of his treacherous kind seizing control of the Orrery for themselves. The Space Wolves had weight of numbers and surprise on their side, advantages that Haakan intended to fully exploit.

That was the last report, before all that could be heard over the vox was a shattering explosion and the sound of battle.

‘Not now, you dogs, not now!’

Huron Blackheart was wild with incandescent rage as the enemy crashed through the wall – not just with hate but with outrage, as if his gods had betrayed him, letting the Space Wolves attack him here and now, when he was on the verge of seizing the power of the Orrery.

Rotaka neither knew what Huron intended nor in this moment particularly cared. His every scrap of effort was focused on not dying.

There had been roughly fifty Red Corsairs when they landed on the Ironshore, and less than half of them were present in the Orrery chamber now. The Space Wolves outnumbered them three to one, and were led by some kind of general, an ancient-looking Space Marine with ornate embellishment on his armour, white hair and beard and a jaw full of thick fangs that made him seem even more of a beast than the rest of his feral kind.

Rotaka’s squad instinctively dropped into a defensive formation, opening fire on the Space Wolves as they crashed into the chamber. The bolter fire would do little but slow the Space Wolves down until they could engage the enemy face-to-face, but a blast from Verbin’s plasma cannon threatened to bring part of the roof down.

‘Do not damage the Orrery!’ bellowed Huron, something close to panic etched on his dead features. ‘Hold this chamber, but do not damage the Orrery!’

Then the Tyrant was away, swinging his claw into the nearest Space Wolf with enough force to knock even a savage Space Marine off his feet. The tide of Space Wolves crashed into the handful of Red Corsairs with swords and axes and fists, and Rotaka was fighting for his life.

Less than an hour after Folkvar had brought her through the Archway to Kerresh, Anju Badya found herself holding a gun and wishing she had stayed on Hacasta to freeze to death. Watching the machines they had been warned about roll towards them, it seemed she and Folkvar had journeyed far for little.

After initially passing through the Archway, she had almost fallen to her knees to kiss the ground of this new world. Her main reason for not doing so was that she feared her current state of fatigue would make it difficult to get up again.

Kerresh was bleak, but lacked the piercing cold of Hacasta. Badya and Folkvar had emerged from the Archway into the aftermath of battle, wrecked enemy defences still smouldering, a rank smoky smell drifting across from a nearby encampment, where the Space Wolves continued to purge the last of the traitors’ mortal servants.

Nonetheless the lack of ice had been a balm to Anju after Hacasta. The heat had begun to seep back into her body, and the layers of protective clothing she had worn through her long journey had begun to weigh heavy. Soon she would be too hot, a state unthinkable in recent days. She needed to acclimatise.

Standing amongst the smoking wreckage she had pulled off her thick gloves, fingers shaking as she did so. Having been exposed to such severe cold for so long, even while insulated, her body was having difficulty adjusting. Her skin tingled with the warmth, not entirely comfortably.

As she peeled off more layers, Badya had tried to concentrate on something other than herself and her body’s reaction to the heat. Folkvar was nearby, discussing recent developments with another of the Space Wolves. Badya and Folkvar had travelled across a hostile world together, but he was still largely unknowable to her, as all the Space Wolves were.

What they did have in common was their loss, the riderless rider and the tank commander without a tank. They had lost their comrades and their steeds in the same battle, left stranded here on two feet.

Although he was a fearless immortal, more a machine for war than a human being, Anju suspected Folkvar’s grief was deeper than her own, a loss compounded by centuries of war and the ancient heritage and tradition of his pack. Anju was glad that she had only one lifetime to lose, and didn’t carry the weight of such history with her.

She flexed her fingers, and stared down at them. The skin had a raw pink hue to it, a shade off from the natural light brown, but her hands had at least stopped shaking. Her wounds from the battle were healing, but she hoped to have some small amount of time before the next conflict.

‘Word from Godrichsson,’ another Space Wolf shouted to the small group that had surrounded Folkvar since his emergence from the Archway. ‘The traitors move against us.’

One of the Space Wolves laughed.

‘We drove them back mere hours ago,’ he scoffed. ‘What do they expect to have changed so soon?’

‘They come with vehicles,’ said the other. ‘Some kind of machinery, converted for war.’

Anju and Folkvar had requisitioned various small vehicles while crossing Hacasta, civilian transports and tracked vehicles customised for the ice and snow. None of those had been an exceptional threat. She had imagined this was something larger, and she was right.

They were not machines of war, but they were engines of destruction: demolition engines several storeys high, fronted with rotating hammers that smashed buildings down and crushed the debris to dust, their upper sections heavily armoured so that any falling rubble would bounce off. The cumbersome, tracked machines had been redesigned, stripped out for speed and equipped with additional armour and weapons. The red saltire of Huron Blackheart was emblazoned on each.

Folkvar made a low grunt, a deep bass noise that echoed in his armoured chest. Anju looked up at him curiously, and to her surprise he answered her unspoken question.

‘These are not true tanks, no machines of war,’ he said. ‘For all their heretical ornaments they have little manoeuvrability, and no serious weaponry. But they are strongly armoured and will crush any obstruction.’

They stood on a rooftop a short distance from the Archway.

‘Then how do we defeat such things?’ asked Anju. The demolition engines were tearing through buildings as they approached, a whole skyline collapsing.

Folkvar grunted again.

‘I say we tear those things to pieces chunk by chunk,’ said a nearby Space Wolf.

‘No,’ said Folkvar. ‘Let them come. We split up, one group to draw their fire and coax them through the Archway if possible, while others attack them from the flanks. On Hacasta we will flourish and their components will freeze. Then we surround them, and destroy them.’

There was a murmur of agreement down the line. As one of the few mortals present, barring a small number of the kaerls who accompanied the Space Wolves, Anju was used to orders and exchanges going literally over her head.

‘This is where we part,’ said Folkvar, looking down at her. ‘You will best serve our purpose by finding a position here on Kerresh from which to strike our enemies, Sergeant Anju Badya.’

She nodded.

‘Fight well, sergeant,’ said Folkvar in his low metallic voice. ‘Prove that I was not wrong to save your life so you could fight again today.’

Then Folkvar was away to form a faction to draw the enemy through the Archway, and Anju was running to find a good firing position, and the rumble of the traitor machines grew louder and louder.

The Space Wolves fought with every bit of the savagery Rotaka had expected of their considerable reputation, but it was Huron Blackheart that Rotaka found himself mentally damning.

Even if Rotaka had wanted to form a protective cordon around his leader and master, as would have been strategically sensible, it was impossible: Blackheart had waded into the incoming mass of Space Wolves with a fury to match theirs, but while the Space Wolves’ ferocity came from their bestial nature, Huron’s was looser, more unhinged. He lashed out with the Tyrant’s Claw with manic energy, not reckless exactly, but without any driving purpose.

As a Space Wolf ran towards Rotaka, dodging a shot from his bolter, Iltz let out a burst of blue flame that briefly disoriented the Space Wolf. Rotaka stepped in to smash his enemy’s helmet with the butt of his bolter, then drew his dagger and swung it up towards the vulnerable joint in the Space Wolf’s armour around the neck. Iltz hovered back at Rotaka’s shoulder, the servo-skull engaging in a crude defensive pattern of distracting enemies as they got close.

‘You allow yourself to be distracted, Rotaka,’ said Hulpin, firing past Rotaka. ‘Do not die easily – such a death dishonours the gods.’

‘I will endeavour to meet your approval,’ said Rotaka. It came out as defiant, but Rotaka knew Hulpin was right. His doubts about Huron were polluting his mind.

The Space Wolf blocked Rotaka’s swing, pushing down the knife, and slammed an elbow into his helmet. Rotaka’s head was knocked back, warning sigils flashing on the display. He smashed his fist into the Space Wolf’s helmet, letting his knife drop to the ground. They were locked together now, each beating the other with fists and knees, armour clashing with metallic clangs. The sigils on Rotaka’s display multiplied as his power armour was damaged in several places, and he guessed his enemy must be experiencing the same.

Nearby, Hulpin was engaged in hand-to-hand combat with two Space Wolves. The rest of Rotaka’s squad were similarly under attack from all directions. Rotaka knew he had to focus.

The Space Wolf cracked first beneath the pressure of malfunctioning power armour, ripping off his helmet to reveal a head that was a mass of scars and piercings, a tattoo running down one side of his face, lank reddish hair scraped across his skull.

Rotaka punched him in the face, but the Space Wolf ducked the blow and slammed a gauntleted fist into Rotaka’s throat. He reeled backwards, lost for breath, the runes in his helmet now screaming at him. He too pulled his helmet off, gasping for breath, and in that moment he could feel the Space Wolf’s killing blow coming down on his exposed head.

Had he been wrong about Huron all along? Did this malaise of Huron’s stretch back to the Palace of Thorns? To before that? Doubt clouded Rotaka’s mind as surely as the pain coursing through him.

Then the Space Wolf was reeling backwards, head on fire, Malinko having unleashed a torrent of burning promethium, while Verbin was at Rotaka’s shoulder, helping him to his feet. Iltz hovered nearby, the dead gaze of the servo-skull a mockery of concern.

Hulpin, Malinko, Verbin, Wuhrsk, Iltz. All his men. The latter was dead, but the rest were alive. They were scum – he hated them for many different reasons – but they were his squad, his scum. When all loyalties withered, he had a duty to keep them alive, to keep himself alive, in the face of both rabid enemies and insane leadership.

Rotaka picked up a discarded Space Wolves chainsword from the ground, and forced himself upright. He immediately had to swing the chainsword upwards to block an attack from an incoming Space Wolf.

As he did so, the Space Wolf with its head ablaze from Malinko’s flame seemed to be taken by some kind of rage, all reason evaporating from its eyes. It seized the servo-skull out of the air, and smashed it repeatedly against the stone floor, ignoring the flame consuming its gauntleted hand.

Rotaka had heard of this, the way that the Space Wolves could lose themselves in the animalistic side of their nature, the wolf within overpowering their intelligence. He had thought them beasts before, but this was a new level of mindless savagery, the Space Wolf lashing out with Iltz as a club before repeatedly striking it against the ground.

Rotaka, now caught between two other Space Wolves, one bringing a sword down against his chainsword while the other slashed at him with a power claw, was left powerless to intervene as the rabid Space Marine smashed Iltz to pieces, components spilling over the ground and the unnatural flame guttering and dying.

Then, when all that was left was Iltz’s burned-out skull, the rabid Space Wolf looked for another target.

Rotaka had kicked away one of the Space Wolves attacking him, giving him seconds to rid himself of the one with the sword. Rotaka pulled his chainsword away, whirling out of reach to let the Space Wolf’s sword pass through the space he had just occupied. A blow from the Space Wolf with the power claw knocked him sideways.

Once again, Malinko intervened to protect Rotaka, diving between him and the Space Wolf before the power claw came down on Rotaka. Malinko received the full impact of the blow from the power claw, tearing through his helmet, and Rotaka was up on his feet, defending him in return, knocking the power claw aside with his chainsword before another blow could be struck.

Malinko tore off his shattered helmet to reveal long scars down his face, blood turning black as it rapidly coagulated and healed. He dabbed at the cuts, and looked down to see the blood on the fingertips of his gauntlets. Then he shrugged and smiled, his mouth warped and crooked, speaking through shredded lips.

‘They add character, yes?’ he said.

Then the frenzied Space Wolf brought the remains of Iltz down into the side of Malinko’s skull, two giant skulls clashing together in a semi-posthumous headbutt.

Malinko went down, the rabid Space Wolf all over him, the bloodied servo-skull being raised and brought down to deliver further blows.

In his frenzy, the Space Wolf had left the back of his neck utterly exposed, not caring about attacks from anywhere else as he battered Malinko. Rotaka took the chainsword and thrust it down the back of the Space Wolf’s armour, shattering the spinal column and leaving the whirring blade digging into his torso.

The Space Wolf collapsed sideways, blood gushing from the collar of his power armour. Iltz rolled uselessly away, burned-out and crushed.

Rotaka pushed the corpse aside but he knew it was already too late. Even a Space Marine’s skull would be crushed by a solid object brought down with that many blows of such ferocity.

Malinko was dead.

On Kerresh, Garreon knew that this was a vital moment. As one of his master’s most trusted advisers, he had been as close to Huron Blackheart as it was possible to get to such a creature; failure now would breach that trust forever. Regardless of his reduced circumstances and the services Garreon had performed in the past, Huron did not forgive repeated failure from anyone, especially in response to a direct, simple order.

Drive the Space Wolves through the Archway. Hold the line.

Garreon was not privy to Huron Blackheart’s thoughts, and for much of the time was very glad of this – who would wish to look inside such a mind?

Not knowing Huron’s plan, all he could do was fulfil that order to the letter.

Drive the Space Wolves through the Archway. Hold the line.

He would make that line, and he would hold it whatever it took, for however long, regardless of cost in lives or assets.

The demolition engines, the bloated machines crushed everything in their path, chewing up the area around the Archway that the Red Corsairs had failed to defend against the Space Wolves’ earlier attack. As they pushed towards the Archway to Hacasta, rolling over their own former defences, the Red Corsairs under Garreon’s command were crammed into armoured boxes within the bellies of the vehicles. Garreon addressed the Corsairs in his presence, and his voice was voxed to those in the other two engines.

They all needed to hear this; he wanted his words to dig into their minds like the sweetest barbs and stay there in the battle that would follow.

‘You all stand on the verge of extinction,’ shouted Garreon. ‘In not defending our territory sufficiently, you have failed our lord and master Huron Blackheart, and the only punishment for such failure is death. Right now, you are already dead.’

He looked down at the Red Corsairs before him. They showed no fear, but that did not mean they lacked a keen sense of self-preservation.

‘You are on borrowed time, yet there remains fleeting hope to live,’ said Garreon. ‘The Tyrant knows no mercy, but if your shame is rectified before he returns to this world, then that achievement will stand and the indignity of defeat will be forgotten. Drive these dogs through the Archway, keep them on that barren world of ice where beasts like them belong, and you may yet still be spared, and still be allowed to fight on as Red Corsairs for the glory of Huron Blackheart.’

There was a roar of agreement, which echoed off the dull metal walls around them, and was repeated on the other engines via vox.

‘Yet fail here,’ Garreon interrupted the cheers, his tone harsher than ever. ‘Show hesitancy or inattention, anything less than utter commitment to the orders you have been given, and the death Huron Blackheart will deliver to you as your rightful master will be a mere mercy compared to the horrors I will inflict on you first. Every agony I have learned in the realms of our gods will be visited on any who do not do their duty now, and each day will seem an eternity of pain, and when your misery is ended your names will be cursed by every Red Corsair for eternity.’

At this, the roar of courage and rage from the Corsairs grew louder. They had been coaxed, enraged and inspired. Now was the moment.

‘The servitors are set to ram these machines through the Archway,’ shouted Garreon. ‘Whether they are destroyed by the Space Wolves or roll on until they fall into a chasm matters not at all. For we know that battles are not won by machines or tricks, or armies of pitiful mortal slaves, but by warriors without fear or mercy, on the ground striking out with bolter and claw.’

Garreon could barely hear himself over the rapturous, raucous agreement all around.

‘Open the doors,’ he shouted. ‘Let us abandon these vehicles before the dogs have even scratched them and show these animals that Huron Blackheart’s Red Corsairs know how to bring beasts such as they to heel!’

And with those words the bolts were drawn back, and the Red Corsairs burst out of the demolition engines to take to the field of battle, and face the Space Wolves who had so effectively set them running only hours before.

To Anju’s horror, the giant demolition engines didn’t just crush buildings, they also spewed out a torrent of Traitor Marines.

The Space Wolves had held back as buildings fell beneath the rotating hammers of the demolition engines, wary of falling rubble, but as the Corsairs emerged the Space Wolves who had placed themselves to the sides of the Archway ran down to engage the enemy, screaming their own feral curses in response to the heresies of the Corsairs.

In the Valley of Blades, Anju Badya had mainly seen machine fight machine, the heaviest weapons wrecking metal in a roar of deafening, blinding explosions. Here, there were just two forces of demigods, brutal traitors and savage beast-men, running at each other with tremendous speed and incredible force.

When the lines met, weapons and armour clashing, it was like hearing a calamitous bell ringing, a metallic, discordant chime loud enough to wake sleeping gods. It wasn’t explosions or gunfire, but a single horrific note, the death knell for worlds.

Anju Badya had her gun in her hands, her shooting position well established, but as the two sets of Space Marines clashed, the weapon hung limp. What place did she have on a battlefield like this? She was just a mortal.

Then she remembered Folkvar speaking to her, as she recovered from her injuries in the underground monastery, about why he had dragged her, broken, from the Valley of Blades to safety.

They had spoken since, in their long journey, and though the towering Space Wolf did not say much, and certainly never repeated himself, she had gathered some more of his beliefs, which helped her understanding.

She could see it now, what the Space Wolves called the ‘wyrd’. The way the Space Wolves thought of the destinies of themselves and others, each life a thread, those threads woven together in a tapestry of history and fate. Folkvar considered her thread might be continued for a purpose. That purpose might very well be to take one useful shot on this new battlefield. Then her thread might be cut, but she would have contributed what she needed to, fulfilling her destiny.

Wyrd was usually spoken of in regard to the lives of great heroes and villains, leaders and warriors, but Folkvar believed that wyrd also governed the smallest of events and the lives of mortals.

Anju Badya was not sure she shared that belief. She was a Tallarn, from a very different world and culture to Fenris, and she had her own superstitions. But she owed Folkvar a great debt for the rescue his beliefs had inspired, and she needed to honour that.

She lifted her lasrifle, found an enemy target, and fired.

On Karstveil, in the Orrery chamber, Wolf Lord Haakan led from the front, sword hacking through traitors, and he could feel in his old bones that his Space Wolves had the advantage. He had lived so long, through so many battles, that the ways of war had become instinct, an extra sense, and he could feel the confusion in the Corsairs’ ranks. Unlike the Rout, few of the Corsairs acted in defence of their comrades, and while for some this selfishness bore fruit, it resulted in a lacklustre defence.

The Orrery itself began to react with agitation at the activity below, and the crackling bolts of energy that flickered between the spheres and the pit below started to flail, catching the Space Marines in the chamber with coruscating arcs of raw power, burning through power armour and flesh alike. As the Corsairs and Space Wolves fought they dodged these bolts, trying to draw each other into the bursts of energy.

Haakan had hunted down and slaughtered many enemies of the Imperium over his long life, and intended to add Huron Blackheart to the list. As Blackheart slashed his way through his enemies with the Tyrant’s Claw, even knocking aside his own Corsairs as he crossed the chamber to reach the stairway that weaved up the chamber wall, allowing access to the Orrery directly, Haakan pursued him. He caught up to the Tyrant of Badab, drew his sword and let out a feral roar that even Huron Blackheart could not ignore, and his enemy turned to face him.

‘So you lead these beasts?’ sneered Blackheart, and there was a madness in his eyes Haakan recognised from those who had fallen to the deepest heresies.

‘And you lead nothing,’ snarled Haakan. ‘Broken ranks of undisciplined rabble.’

The Wolf Lord and the Tyrant clashed on the stairway, Haakan’s chainsword meeting Blackheart’s claw, flashes of energy discharging as metal met metal.

It seemed initially as if Haakan had the easy advantage, with Huron Blackheart being driven backwards, but it was nothing if not a strategic retreat, the Tyrant of Badab duelling defensively while letting the old Space Wolf push him exactly where he wanted to be – higher and higher.

When they were level with the Orrery, the Tyrant changed his style of fighting, from rapid defensive parries to something more aggressive. As Haakan brought his sword down in a two-handed blow, Huron didn’t defend himself, instead ducking back and out of the way, reeling aside and close to the wall. His back to the wall, he planted a solid kick into the side of Haakan’s leg, knocking him towards the edge of the stairway, close to a trail of wispy red energy leaking from the sphere representing Kerresh.

Haakan ducked under the trail of energy, the tendrils of which seemed to grasp towards him, and made to attack Blackheart again with an upwards thrust from his sword.

But Huron Blackheart was on the move, running three steps up and vaulting over the edge, landing on one of the floating platforms between the moving spheres. Although it looked ethereal, the jade-like stone translucent and glowing, it held as solidly as if it were planted on bedrock, even with the weight of Huron Blackheart upon it.

Haakan followed seconds later, landing with a roll on the narrow platform, coming up out of that roll with his sword raised, swinging it towards Huron once more.

The two warriors clashed again, but this time without subterfuge or restraint, the Tyrant’s bulky power claw moving as fast as the slimmest blade, clashing with Haakan’s sword, trying to knock it to one side, while the Wolf Lord pressed the offence, swinging around with blows that Huron needed to raise his gauntlets to deflect, chips of ceramite flying as the ancient blade hit his armour with incredible force.

The sphere of Karstveil, the very planet they were standing within, spun between them and both Huron Blackheart and Haakan backed away from the other, allowing it to pass.

‘Traitorous filth,’ roared the Wolf Lord, the hairs of his white beard sticking out, charged with static in the midst of so much raw power.

The Tyrant, for his part, simply stood back, addressing not Haakan but some other presence in a low murmur, and as the Wolf Lord watched, something liquid and semi-visible moved from Huron’s shoulder, jumping not to attack Haakan but out onto the sphere of Karstveil, scampering weightlessly over its surface before leaping out into the Orrery, bouncing over the planets, its silhouette visible as the energies seeping out of the spheres crackled around it.

Then the Tyrant’s attention was back to Haakan, and he lunged forwards. The Wolf Lord deflected the blow, and then as Huron swept his power claw to deflect him Haakan ducked under his arm, bringing his sword up in a blow that drove into the Tyrant’s skull from below.

The blade sunk into Huron Blackheart’s chin, black ooze dripping down the blade, a glassiness entering Huron’s single organic eye. A guttural sound began to emerge from the Tyrant’s throat, a hacking, doomed splutter.

‘You think yourself a tyrant, a master of worlds,’ snarled Haakan through his fangs. ‘Yet you die like any other traitor, broken.’

The hacking cough continued, and Huron’s face contorted in spasms that rocked his entire body. Haakan held the blade tight as Blackheart jerked in his grasp.

Then Huron’s eye focused on him, and his mouth opened in a hideous grin, the metal of Haakan’s blade visible from behind rows of blackened teeth, the guttural sound echoing behind it.

Huron Blackheart wasn’t coughing his last breath.

He was laughing.

One blade on the Tyrant’s Claw slid between the plates of Haakan’s armour, unimpeded by the arms gripping the sword. It pierced one of the old Space Wolf’s hearts, and Haakan felt a blast of blinding pain in his chest, enough to cause him to temporarily release his grip on his sword.

The sword came free and fell to the platform, bouncing off and tumbling down into the chamber below. Huron Blackheart cricked his neck and rolled his tongue around his teeth, drool dripping out of the wound on his chin.

Haakan, body wracked with pain as it adjusted to the loss of one heart, clenched his fists, about to strike back at Huron Blackheart, to tear him apart with his bare hands, to rip that damn claw off him and cut his thread with it.

But Huron Blackheart didn’t attack with the claw; he spun around and kicked Haakan in the chest, knocking him off the platform.

For a brief moment, in mid-fall, Haakan believed that Huron had conceded the duel, that he was being cast out of the way to fall a survivable distance to the cavern floor below, just to remove him from the Tyrant’s path.

Haakan believed this for the last second of life, before his huge, armoured body collided with the sphere of Hacasta, smashing through the brass orb and unleashing the wild energies within.

There was a second of intense agony for the Wolf Lord as raw power surged through every cell of his body, then Haakan and the representation of Hacasta both exploded, particles of organic matter and fragments of burned ceramite scattering in all directions.

Huron Blackheart showed no satisfaction at his victory over the Wolf Lord – he had other concerns. At his unspoken command, the Hamadrya, his familiar, was leaping through the Orrery, seizing strands cut loose by the destruction of the representation of Hacasta, moving them around the Orrery, re-connecting flows of power between worlds.

Opening a path, a trail between worlds, which would take Huron Blackheart straight to the centre of the Hollow Worlds, to the forbidden sphere at the centre of the system.

To Exultance.

On the very boundary between the real worlds of Hacasta and Kerresh, Anju Badya had found herself drawn into the heart of the battle between immortals.

The front line between the Space Wolves and the Red Corsairs had become fluid, pushing back and forth. The Corsairs had abandoned their unwieldy vehicles, leaving them to roll through the Archway and bury themselves in the Hacastan snow, but had proven reluctant to follow, pressing their advantage to drive the Space Wolves back to Hacasta but frequently dropping back, holding a line somewhere at the Archway’s edge on Kerresh.

In the face of the Space Wolves, such hesitancy was potentially fatal, and the Space Wolves hammered this wavering line, throwing the Corsairs into confusion.

Her own position compromised by mortar fire, Anju found herself fighting alongside a small group of Space Wolves, although ‘alongside’ might be a misnomer as she ducked around them at elbow level, trying not to get accidentally decapitated by her towering allies.

As the Space Wolves descended on two isolated Red Corsairs with claws and other melee weapons, Anju looked around for a target to fire on with her lasrifle. She couldn’t hope to do serious damage to a Traitor Marine, and to get too close to one would be fatal, but she could prove a nuisance, distracting them with her shots and allowing a Space Wolf to pounce.

The snowstorms on Hacasta had briefly died down, and the view between worlds was clear through the Archway. Looking through the gate, Badya saw Folkvar fighting three of the Traitor Marines at once. While he wielded a shortsword to each side, using his gauntlets to block their blows, there were too many of them, and savage attacks from their axes and chainswords began to chip away at his armour, hitting the vulnerable joints.

Anju raised her lasrifle. She didn’t know whether it would even work when fired through the Archway; she doubted it could even scratch one of the Red Corsairs, but she owed it to Folkvar to try – he had carried her from the site of defeat and given her a second chance to redeem herself. For them to both redeem themselves. Even if she just irritated his attackers enough to distract one, to bring one of the Corsairs chasing after her, it would be worth it.

She fired, but the las-shot fizzled out when it hit the iridescent barrier of the Archway. When the ripple effect of the shot being absorbed dissipated, she could see that Folkvar was on his knees, and the Red Corsairs had taken his helmet off. His face was dominated by the shovel-shaped augmetics that covered where his mouth and nose had once been, but Folkvar’s eyes were still intact, still organic. Even across a distance, through the distorting lens of the Archway, Anju Badya could see those eyes looking back at her.

She ran. If the lasrifle wouldn’t work through the Archway, she would cross the threshold and attack the Red Corsairs in person. She would fight to the last breath, no matter how futile.

Then the ground beneath her feet seemed to jerk upwards, like a stalled elevator, and she was thrown off balance, falling forwards just an arm’s length from the Archway.

Through the Archway, she could see that whatever tremor she felt had also struck Hacasta. The three Red Corsairs had tumbled out of the way, leaving Folkvar where he was, more firmly planted to the ground while forced on his knees.

And behind him – and by the Emperor, Anju could not believe what she was seeing – the world itself seemed to be shaking apart, chunks of the ground rising into the sky, the whole curve of Hacasta folding in on itself. While the ground nearest to the Archway appeared relatively stable, the horizon seemed to be bending away, swirling towards an artificial sun which had turned black – not the absence of light but something deeper, a hole in the world.

Only a short distance and a world away, Folkvar looked up, his eyes locking with hers. He nodded, in some silent acknowledgement, and Anju remembered what he had said in the cave, that she had survived the battle in the Valley of Blades, and that she would survive further.

Now she was surviving again. She returned Folkvar’s nod.

Then he was torn away, as was the whole of Hacasta, the iridescence of the Archway consuming itself and the stone of that great arch collapsing, falling down, and Anju Badya had to scramble to her feet and run before she was crushed, but as she ran she was less scared of what might happen to her, and more consumed by what she had seen.

Hacasta was gone, an entire world destroyed, torn out of the stable system of the Hollow Worlds. What did it mean? What would happen to the rest of these worlds, now one had gone?

Above her head, at the centre of Kerresh, the sun itself began to flicker and dim.

Part Three

The Fall of Badab, long ago

Badab Primaris was falling. From the parapets of the Palace of Thorns, Captain Rotaka of the Astral Claws Chapter could see the skyline crumbling before his eyes. The enemy had undermined the foundations of the very city somehow, their sabotage destabilising the capital of the entire Badab system.

Rotaka’s whole world was collapsing, everything the Astral Claws had fought for and created tumbling down before his eyes.

‘A sad sight, brother,’ said Librarian Iltz, standing beside him.

‘It is,’ said Rotaka, surprised by Iltz’s presence. The Librarian had disappeared into the Chapter’s vaults months ago, and Rotaka had barely seen him since. In the tumult of those months Rotaka had not registered this absence, but now he realised how unusual it was. Rotaka and Iltz had fought on battlefield after battlefield across so many worlds in the years since they were elevated to the Astral Claws, and yet had drifted apart without Rotaka even noticing.

‘They close in, the enemy,’ said Rotaka. ‘Soon they will come for us.’

‘“The enemy?”’ quoted Iltz. ‘Have you forgotten who it is we fight?’

Rotaka looked sideways at his old friend. They had saved each other’s lives so many times, and been the closest of brothers since their initiation. In the long years they had fought the many perils of the Maelstrom Zone, which the Astral Claws were sworn to protect from the horrors of the Maelstrom itself. They had crushed insurrection and dissent in the Badab System as their Chapter Master, Lufgt Huron, tightened his grip on the planets under their protection.

Then, when Huron had defied the Imperium authorities by strengthening the Astral Claws so that they might continue to fulfil their sacred mission, rather than letting themselves be defeated while adhering to the petty rules set down by Terran bureaucrats light years from Badab, they had found themselves fighting other Space Marines, loyalists from many Chapters sent to depose the Tyrant of Badab.

It had been in the last months of that conflict, the steps towards the defeat they now faced, that Iltz had withdrawn to his books. How he had been allowed to retire from the battlefield without censure Rotaka could not imagine, but somehow he had.

And now, at the end, he was back by Rotaka’s side, and with a question.

Who were they fighting? Their brother Space Marines, that was who they fought. That was the answer Iltz sought from Rotaka, though he did not know why.

‘Enemies,’ said Rotaka, refusing to play. ‘We fight our enemies.’

Iltz seemed to think this through, his thick eyebrows furrowed. ‘Come with me,’ he said, stepping away from the edge.

Rotaka followed as Iltz led him back into the palace, beneath the thorned arches and down a winding stairwell.

‘Where have you been these last months, Brother Iltz?’ Rotaka asked, cursing himself for being drawn into Iltz’s mind game, whatever its purpose. Iltz had always been the nimble thinker, even before he became a Librarian, while Rotaka was always the simple soldier.

‘Studying the archives,’ said Iltz. ‘Seeing where we came from, thinking about what we have become.’

Rotaka did not like this kind of talk, and stared silently at the back of Iltz’s head as they descended the stairs.

‘I have also been uncovering some of our Chapter’s secrets,’ said Iltz. ‘Secrets unknown to even Huron himself.’

Iltz stopped, and Rotaka stopped too, not without annoyance – they had arrived nowhere, instead halting at a point between floors, where sculpted tendrils surrounded a small alcove containing a reliquary. Rotaka must have passed it a thousand times before, and had never given it much thought.

‘Iltz,’ he said. ‘Have you lost your mind in your isolation? This is no time to be inspecting relics.’

‘I’m not,’ said Iltz. He lifted the reliquary, turning in the narrow spiral stair to wave the box at Rotaka. ‘Do you know whose remains are in here?’

Rotaka sighed. ‘No idea.’

‘No one’s,’ said Iltz. ‘It’s set dressing, a fake memorial. Who would notice another mark of death in a palace like this, filled with such things?’ He threw the reliquary over his shoulder, where it clattered down the stairs, and punched four seemingly random points inside the alcove with his gauntleted fist.

An entire section of wall swung open with a creak and a release of musty air.

Iltz looked up at Rotaka and shook his head. ‘You thought me insane for a second there, I could tell,’ he said. ‘Such little faith, old friend.’

Rotaka began to speak, unsure himself as to whether he was about to apologise or justify himself, but Iltz waved him silent.

‘Don’t say anything yet,’ said Iltz. ‘If you don’t think me mad yet, you probably will when I explain my intentions.’

Iltz ducked through the hidden door, and Rotaka followed.

The room they entered was wide, but low ceilinged, a dust-covered control room with a central cogitator covering a whole wall. A panel on the front of the cogitator displayed a line of glowing glyphs. Burbling pipes stretched across the ceilings and walls – someone had built this room in the space between the floors, hidden it in the functional absences within the palace structure.

‘What are they?’ Rotaka asked, indicating the glyphs.

‘Those,’ said Iltz, patting the cogitator as if it were a pet, ‘trigger certain high explosive packages embedded in the superstructure of this palace. A weapon of last resort, to lash out at the end. And now, that end is here.’

Rotaka weighed up the options. ‘If you know which explosives these control, we can detonate certain sections of the palace as the enemy attack,’ he said, a wave of hope rising. ‘We could trap and kill the first few waves, or at least take them down with us.’

‘We could,’ said Iltz, standing tall and looking Rotaka straight in the eyes. ‘But that is not my intent.’

‘Then what is?’ asked Rotaka. ‘If you have a better plan, tell me.’

Iltz paused. The chamber was dark, lit only by a series of low lights strung above the cogitator and the glyphs themselves. Iltz’s face was partially in shadow, hard to read.

‘I intend to destroy the outer defences of the Palace of Thorns before the final attack,’ said Iltz. ‘I intend to let “the enemy”, as you call them, walk right in and kill us all.’

Rotaka laughed. He had never grasped the subtleties of his friend’s arcane sense of humour, but he did appreciate it.

Iltz wasn’t laughing. He didn’t react as Rotaka laughed, and he didn’t flinch when Rotaka stopped laughing and swung his bolter up in one fluid motion.

‘Why?’ said Rotaka, staring down his bolter at Iltz. One squeeze of the trigger and his friend’s head would be dripping off that low ceiling. ‘For the sake of the Chapter, why?’

‘We have lost our way,’ said Iltz. ‘Our Chapter was formed to protect this sector for the Emperor, yet now we lash out against our own brothers.’

‘They are trying to kill us,’ snapped Rotaka. ‘Should we have just let them invade, put us all to the sword?’

‘Perhaps,’ said Iltz. ‘I believe they may be right to chastise us, brother. Huron has led us down the wrong path. The experiments, the subterfuge? These are the ways of the heretic Legions, the same mistakes Horus made when he betrayed the Emperor. We have strayed down the same path, and we should repent now.’

‘Repent?’ snapped Rotaka. ‘We are under threat of extinction, and you talk of the battles of dead men long gone, myths from millennia ago. Everything we have done, everything Huron has led us to do, has been to strengthen our position, to fight for Badab and to take the rewards we deserve. If the Imperium would see us die rather than break ancient rules, then to hell with the Imperium and its superstitions.’

‘And the Emperor?’ said Iltz. ‘What of Him?’

Rotaka didn’t answer. Instead, they remained in silence for a short while, Rotaka pointing his bolter, Iltz standing silently.

‘If you are so determined to betray us, why did you bring me here where I could stop you?’ said Rotaka.

‘I hoped you would agree with me,’ said Iltz. ‘I have always trusted your judgement, old friend, and I hoped you would see that we are traitors already, and that the only honour for us is in death.’

‘I will not die easily,’ said Rotaka, shaking his head. ‘I am not a traitor. I have stayed loyal to my Chapter Master, who has sought only to defend us. Why should I show fealty to an Emperor whose armies would end us all? Why should I let you help them?’

Iltz shrugged. ‘We are already dead.’ He raised his hand, slowly and clearly so Rotaka saw he wasn’t drawing a weapon. ‘Those mortals, dying in their habs for our sins, they have lived.’

‘Mortals,’ spat Rotaka. ‘Pathetic, terrified creatures. Their lives are worthless.’

Iltz shook his head. ‘They fear because they have lives to lose, while we are so fearless because we have nothing. We are machines made to kill, to serve a cause, and now we have betrayed that cause we have nothing left. It’s time to end this.’

Iltz’s words were so perfectly calm, so placid, that Rotaka was completely taken by surprise when the Librarian’s raised hand whipped across and batted his bolter away. The Librarian pushed the bolter down, pulling Rotaka forwards, then smashed his armoured elbow into Rotaka’s unguarded face.

The blow stunned Rotaka, and the bolter slipped out of his grip and fell to the floor.

‘I’m sorry,’ whispered Iltz, leaning in close as Rotaka slumped forwards. ‘You may not agree with me, but I cannot let you stop me.’

Rotaka roared as he pushed himself up, ramming his full body up into Iltz, shoulder first. His rage gave him enough adrenaline to lift Iltz off his feet, slamming him into the ceiling. Dust and masonry fell down on them like rain as Rotaka stumbled beneath Iltz’s weight before flinging him to one side.

Iltz crashed into the pipes on the walls, and oily water began to leak across the rough stone floor.

‘Stay down, traitor,’ said Rotaka, spitting blood. ‘I will break you and take you before our master, so that justice can be done.’

Iltz pushed himself up onto one knee, drips from the broken pipes rolling down his arm as he dragged himself up the wall, the fingers of his gauntlets digging into the masonry, which powdered in his grip.

‘We are all traitors now,’ said Iltz. ‘We are not fit to decide what justice is.’

Rotaka’s bolter lay on the floor between them, and Iltz lunged forwards to grab it.

Rotaka was ahead of him, and kicked the bolter aside before bringing his armoured fist down hard on the back of Iltz’s head. They were Space Marines, gods amongst mortal men, but their unarmoured heads were no match for a blow from their own power armour, and Iltz collapsed, blood dripping down his shaved skull.

‘Why are you not armed?’ spat Rotaka. ‘Do you want to die?’

Iltz laughed a delirious laugh, low and bubbling.

‘And you say my humour is strange,’ said Iltz through pained gasps. ‘Why do you think I’m here if not to die?’

Rotaka shouted with exasperation, his voice echoing in the narrow, empty space. ‘You want me to help you, you want me to kill you? Which is it?’

‘Either,’ spat Iltz, crawling on his elbows towards the cogitator. ‘Both.’

As Iltz slowly crossed the room, too stunned to raise himself even to his knees, Rotaka walked in the opposite direction and tore a long length of pipe from the wall. He weighed it in his hands: it was crude, but it would do.

He walked back and smacked the pipe into the back of Iltz’s head three times.

‘Stop,’ Rotaka barked. ‘Stay down.’

Iltz reached up to the nearest glyph with a shaking hand.

Rotaka screamed, a visceral noise from deep within himself, and thrust the pipe downwards. It pierced Iltz’s neck and cut deep into his body.

Iltz looked up at Rotaka, and tried to grab the pipe, to pull it from the wound. But his hands couldn’t move with enough dexterity to get near to it.

Rotaka held the length of pipe and kept pushing it down. Iltz’s body shuddered, the vibrations quivering up the pipe, and it nearly slipped out of Rotaka’s grip.

There was an expression of distant confusion in Iltz’s eyes, then nothing more.

Rotaka pulled the pipe free, then tossed it away in disgust. He staggered away from Iltz’s body and sat against the broken wall, letting the foul, dripping water flow over him.

He stayed there for some minutes.

Then he stood up, walked over to Iltz’s body, and lifted up the Librarian’s boots. He dragged the body away by the ankles, a heavy mass of muscular flesh and power armour.

Rotaka didn’t know where he was taking the body, or what he would do with it, but he couldn’t bring himself to leave Iltz behind.

Twenty-Three

Weeks after the destruction of Hacasta

It was a winter such as even the Sons of Russ had never seen, of a kind entirely unlike the bitter, never-ending winters that forged the people of Fenris into warriors, nor the perpetual winter of swirling, slicing blizzards that had plagued now-lost Hacasta.

This winter was not that of an icy death world, no inhospitable weather phenomenon. No lighter, warmer seasons would come; the cold would never break, only slowly worsen. There would be no spring.

This was a final winter for Kerresh, the winter at the end of a world. The destruction of Hacasta and realignment of the Hollow Worlds’ Archways had catastrophically broken the flow of power in the system, and Kerresh’s artificial sun was dying, flickering like a broken lumen globe. What light it gave out was impure, the broken sun leaking radiation, its very rays poisonous.

Under the fading sun, winter had descended, not from internal weather systems – they too were failing – but from the draining of life and power from the world itself. The ground became dry and cold; the air chilled and became thinner.

The mortals left on Kerresh began to die. The weakest first, the oldest and youngest, left short of breath as the atmosphere worsened, poisoned by increasingly harsh water, starved as food withered, slowly killed by the poisonous sun overhead. First the weak, but then the stronger ones too. Only those who had the resources to find clean water and protect themselves from the harshening environment could survive on a dying world.

Those mortals, resourceful as they were, mainly walked alongside the immortals, who were unaffected by the devastation of dying Kerresh.

Across a cold and hostile plain, a rider sat low in the saddle, covered in layers of protective clothing. Beneath her scarves, she wore a rebreather, and her eyes were covered with thick goggles. Leather gloves gripped the reins, and ran all the way up to her elbows. No patch of skin was visible to be touched by the sun’s poisonous light, and the canteens hanging from her saddle were full of purified water.

Her mount was one of the few creatures to thrive in this atmosphere. Anju Badya had found it, alongside the others the mortals in their company now rode, in some kind of farm a short distance from the ruins of the Kerresh/Hacasta Archway. It was tall, with spindly legs and a plump body, with a long neck and small head. Covered in scaly red skin, it was presumably some kind of lizard, or maybe an amphibian.

Odd as they looked, the creatures had proven to be excellent riding stock, and could traverse long distances with only minimal sustenance.

Anju had grown quite fond of her red-lizard-chicken-thing. It wasn’t a horse, but for the purposes of scouting this desolate world, it would do. She had called it Folly, as she thought that the surviving Space Wolves would take unkindly to her naming it directly after Folkvar.

Folly slowed to a trot on entering the encampment, and ducked down to allow Anju to dismount. She did so, legs aching from stretching themselves over the creature’s rotund body, then led it back to its pen so it could eat and drink.

The camp was a temporary one. The Imperial forces moved every couple of days, once the next target or stopping point had been scouted. They were tracking the Red Corsairs across this dying world, eliminating their outposts when located, seeking information as to where their enemies were moving next.

The worlds had been realigned, and everything had been thrown into confusion. At least one old Archway had gone, but intelligence gained from raiding enemy camps suggested that, somewhere on Kerresh, another had risen to take its place, and that the traitors would be using that to escape this dying world, and moving on to the next stage of their plan.

So scouts like Anju, who could cover great distances at speed, were sent out to discover what they could.

She found the Space Wolf she needed to report to by a fire, as was his way. The flame was weak and purplish in colour, an unnatural blaze, but still he sat by it. He was helmless, as the Space Wolves had no problem breathing the failing air of Kerresh, though his greying beard looked filthy and lank from the pollutants in the atmosphere.

‘So,’ said the Space Wolf. ‘Have you found the Archway?’

‘No, my lord,’ said Anju. ‘But–’

Before she could speak the Space Wolf spat on the fire. She was unsure whether this was in contempt of her, or their lack of progress in general.

‘Go on,’ he said.

‘An enemy stronghold, my lord,’ Anju reported. ‘Some kind of secure facility they have overrun. They seem to be in the midst of evacuating.’

‘What kind of facility?’ asked the Space Wolf.

‘Hard to tell from a distance, but heavily guarded,’ said Anju. ‘The Red Corsairs protect it themselves, rather than trust mortal slaves.’

The Space Wolf grunted.

‘There was one other thing I saw, my lord,’ said Anju. ‘The patrol patterns and movements were unusual. A heavy presence at ground level within the perimeter, but few high-placed sentries and no hardpoint defences on the walls.’

This aroused the Space Wolf’s interest and he was on his feet with such speed that Anju instinctively stepped back.

‘Prepare to ride again within the hour, Sergeant Badya. We will strike at the first opportunity,’ said Anvindr Godrichsson. ‘For the traitors to order their defences that way, they must be more concerned with someone getting out of there rather than anyone getting in. I would meet the prisoner who requires such measures.’

‘Your brothers will believe you are dead,’ Garreon had told him, back when his ordeal was still fresh. ‘They have seen the station destroyed with you in it. Before they have time to dig through the ruins, looking to harvest your precious gene-seed and salvage your armour, our forces will already have driven them back from this world, and many of them will be dead.’

Tormodr had wanted to bite the side of the heretic’s face off, but the chains restrained him.

‘You will wish you had died too,’ Garreon said, leaning in close, seeming to savour each word. ‘That would have been glorious, wouldn’t it, dog? A noble death, with honour. There will be no honour for you now, though, only pain.’

It had taken three Red Corsairs to drag the struggling Space Wolf away, onto the ridge runner that had taken them from the factorum on Kerresh to the facility he had been imprisoned in for these last weeks. Sindri, his head injured in the battle with the Corsairs, had been unconscious through the entire journey, and Tormodr had not seen him since.

He had seen Garreon again, though. After a few days chained up, the ‘Corpsemaster’, as his lackeys had grandiosely referred to him, had entered Tormodr’s cell to begin his interrogations, presuming that Tormodr would be sufficiently weakened for the next stage of his torture.

Tormodr had laughed in his face, and the Corpsemaster had left in a fury, screaming at underlings to perform various acts upon Tormodr’s person, to prepare him for the more precise torments to come.

The pain was brutal and relentless, but it did them no good. He was of the Rout, a Sky Warrior, one of the Vlka Fenryka, a Space Wolf, a Son of Russ, a Fenrisian. He was not just a single warrior, driven by pride or ego or even honour – he was part of an endless tradition of war. His thread was just one of many that wove through a history of countless conflicts, and his suffering was only a passing moment in that greater history.

They could torture him, these Red Corsairs, Traitor Marines tied up in their petty feuds and ambitions, but as they did he withdrew not into himself, but into the greater truth he was a part of, a timeless world of Space Wolves hunting across the snowbound plains of Fenris, of battles against ceaseless enemies whose faces changed but who died as easily as each other.

When he felt that Tormodr was truly prepared, the Corpsemaster returned, with further agonies to inflict. He had questions and demands, but Tormodr didn’t answer the former, and laughed off the latter.

This Garreon, with his thin face and his needles, dripped poison in Tormodr’s ear – sometimes literally, leaving the inside of his skull burning, and sometimes as heretical words and suggestions that burned in a different way. He threatened, he persuaded, he tormented Tormodr, trying to bring him to his side, to recant the Emperor and Russ, to take up the banner of the Red Corsairs and Huron Blackheart, to embrace the Dark Gods.

Some part of Tormodr heard these words, and some part of him might even have been angered or offended. Certainly, a large part of him was in constant, but varying, pain.

But a part of him was forever free, countless light years away from Garreon’s torture chamber, knee deep in the snows of Fenris, tracking prey that had just disappeared beneath the trees.

That part Garreon could never reach and eventually, after countless sessions of torture over numberless days, the Corpsemaster had stormed out of the torture chamber never to return.

Tormodr slept, and dreamed of the Aett, of a stronghold that towered over even the mountains around it.

He awoke when he fell to the floor, face down. He had been unchained, and he tried to move, but Garreon, even though he had failed to extract secrets or fealty from Tormodr’s lips, had performed his torments well enough to rob him of any physical aptitude, at least without further healing. Tormodr’s nerves were utterly disrupted, his muscles limp, and the best he could do was jerk slightly on the ground.

‘Stay down, dog,’ rumbled a voice, and Tormodr felt a kick to the side of his head. That simple pain, the shocking blow, felt almost a relief after the subtler forms of pain inflicted by Garreon, and woke him a little. Not enough to stand, but enough to twist his head around to look at whoever had kicked him.

Three skulls at the waist, then above that, the shadow of a horned helmet.

‘Traitor,’ mumbled Tormodr, as more of an observation than a taunt, and closed his eyes. He was woken suddenly again as he was pulled backwards. Traps were being fitted over his hands, metal devices presumably to stop him trying to unpick any locks or otherwise freeing himself.

The traitor with the horns was accompanied by another of the same breed, the aquila on his armour scratched away and replaced with the red saltire of the Red Corsairs.

Tormodr felt the rough surface of the wall rubbing against his naked back. He was being leaned against a wall in a sitting position, rather than trussed up.

‘Told to make me comfortable?’ he slurred through a loose-feeling jaw. Whatever drugs had been pumped into him, they still hadn’t worn off yet.

The horned traitor punched Tormodr in his jaw, and the sharp shock was like a tonic. Much more punishment of this simple kind, and he would be on his feet in no time.

‘Shut your animal face, hound of the Emperor,’ snarled the voice beneath the horned helmet. ‘You are no more than a pet to a long-dead god, and now you will be Garreon’s toy to play with as he wishes.’

Tormodr laughed, spitting a little blood.

‘Am I the toy?’ he taunted, his voice coming back to him through dry, bruised lips. ‘Am I the pet? I’m not the one running errands for an ineffectual sadist. Great freedom you have there, traitor. Betrayed your Emperor so you can do chores for the likes of Garreon.’

The horned traitor pulled back his fist to strike again, but the second Red Corsair waded in to hold him back.

‘Verbin, leave him,’ hissed the other. ‘Garreon doesn’t want them harmed.’

Them? thought Tormodr. Did that mean Sindri was still alive and nearby? Then there was hope here. Tormodr’s spirits rose further. One Space Wolf might hold out hope of being able to break free, but two Space Wolves captured in the same place? Nothing could hold them for long, especially if the guards were distracted by their own anger.

‘Yes, listen to your friend, Verbin, you have orders to follow,’ Tormodr boomed, flexing within his chains. ‘Better look after me well or your master will slap you, little traitor.’ He wriggled slightly on the spot. ‘I’ve got an itch here, Verbin, could you lend me those horns of yours to scratch it?’

The two traitors marched out of the cell, securely bolting the door behind them, and even though he was too tightly chained and grievously injured to have any immediate hope of getting free, Tormodr laughed until long after the two traitors must have been out of hearing, laughed and took the pain that ran down his chest with each laugh as a sign that he was still alive, and that his fight was far from over.

When Pranix had first awoken in his cell, it was to pain, and darkness.

Inquisitors had finer minds than others. They were trained to cut through illusion, through the confusion injury and disorientation could bring, through the false presumptions weaker minds could fall to so easily. Concentrate, concentrate, concentrate.

He was lying face down, on cold wet stone. He opened his eyes, forced them to focus. It was dark, but he could see, dimly, that he was in a small cell. He could hear nothing.

With great effort, he pushed himself up to his knees, each muscle aching, his skin ablaze. He felt scourged, even though he was still fully clothed.

The room swam, and Pranix had bent over onto his hands and vomited, attempting to do so away from himself rather than staining his clothes further. He was unsure of what filth he was covered in, but did not want to worsen the situation. He stood, his throat and nose stinging.

He was still wearing the body armour, though his robes were gone, as was most of the shining ceremonial plate that he, as an inquisitor and a general leading Adeptus Astartes into battle, had taken to wearing. It was the tough material beneath, not the resplendent surfaces attached, that had doubtless kept him intact in his journey.

The journey. Pranix had pieced it together from splintered memories. The furies had descended at unnatural speed, sorcery swirling around them. As they had flown away with Pranix in their grip, clawed fingers sinking into his flesh, swooping close to the roofs and treetops of Ressial, the matter below seemed to fold and shrink, in a blur of un-time that could have been days or weeks or minutes.

Sorcery, powerful witchcraft, must have drawn the furies and their captive back to wherever they had deposited him. Pranix had tried to piece together anything from between that hideous journey and waking in his cell, but everything was too fuzzy.

The fell magicks that had spirited Pranix and the furies across such incredible distances were phenomenally dangerous, and anyone who had undergone such an experience would be at grave risk of corruption themselves after such exposure.

Had he been tainted? No, he was sure it was not the case. His hatred for the traitors burned strong. He was as determined to grind them into dust and retake these worlds in the name of the Emperor as he ever had been.

If his body still ached beyond reason, it was because he held on to his will, because he had held off the corruption and the touch of Chaos still burned him, a filth more rank than whatever foul liquid he was covered in.

It was then, regaining his senses, that he could feel it, the presence of the enemy, the shadow of Chaos. Not there, in the cell, but outside, in the corridors and rooms around him.

He had reached out, and his psychic effort had been repelled. The enemy had their wards and talismans too, and they were everywhere, penning him in.

Pranix had realised then that, however he was going to get out – and he was determined to escape his cell – it would not be with the aid of his psychic powers. He would need to find another way.

Days passed, or at least seemed to. Pranix slept, exercised, performed other necessary physical functions, tried to keep his mind sharp and slept as much as he felt able to. If anything, imprisonment was keeping him in better condition than he had been before his capture – he had time to take the rest denied to him over years of service to the Inquisition.

Pranix did not let his own failure to mark the passing of days during captivity, his lack of awareness as to whether it was night or day, trouble him. Disorientation was only an advantage to the enemy if you allowed it to be.

Then one day the door opened, and his captor entered, ducking beneath the arch of the door, which closed behind him. He held a candle, the light of which was low and guttering, but burned fiercely to Pranix’s light-deprived eyes.

His eyes adjusted enough for him to peer at the newcomer, who seemed to take up most of the cell.

Although his body armour was filthy and shredded, Pranix felt over-dressed compared to his captor, who wore floor-length scarlet robes and a matching full-head hood with narrow eye slits. From his sheer size the newcomer was clearly a Space Marine, doubtless a traitor, but he wore no power armour and carried no visible weapon. The hand that held the candle in its rusty holder was brutishly oversized but pallid, the white skin patched with a rash as red as his robes.

‘Inquisitor,’ said the Red Corsair, a slight slur to the voice that came from beneath the hood. He bowed slightly, an absurdity in the circumstances. ‘I am Anto of the Red Corsairs, formerly of the Astral Claws, formerly of the Tiger Claws.’

‘Traitors and heretics all,’ snapped Pranix in return, his words ringing clear despite weeks of silence. ‘Should I be impressed by such an ill-starred career path?’

A foul, gurgling laugh came from beneath the hood, and the shoulders shrugged as if to say: perhaps, perhaps not.

‘You should be dead,’ said Anto, pointing a black-nailed finger at Pranix.

‘Sorry to disappoint you,’ replied Pranix. If this was supposed to be intimidating, Anto wasn’t doing a very good job.

Anto shook his head. ‘No, you misunderstand,’ he said. ‘If I had wanted you dead, you would be dead. It is Huron Blackheart who sought your demise, to remove the head from the enemy. Yet still you live. Do you know how rare it is for the target of Lord Huron’s ire to survive?’

‘I suppose I have you to thank for that?’ said Pranix.

Anto nodded again. ‘The Tyrant is brilliant in many ways, but he is hasty to strike down those who might yet prove useful,’ he said. ‘Those of us who take a longer view sometimes need to intervene for the greater good, not that you would think of it as such.’

‘I’m never going to be useful to you, traitor,’ said Pranix quietly.

Anto gave another guttural laugh.

‘You say that, but I have observed you at work, inquisitor, seen you from afar,’ said Anto, wagging a finger. ‘You are not one of the blind faithful, preaching loudly from Inquisitorial teachings and thinking that belief and the strictures of the Inquisition are enough to do your work. No, you are a pragmatist, Inquisitor Pranix, a realist, as much as one can be in a universe like this.’

‘Flattery won’t get you any further than threats,’ said Pranix.

‘I mean to use neither,’ said Anto. ‘I simply ask you to take the longer view, and consider your circumstances. For now, you will hold out against any torture or technique I might apply to you. There are other prisoners here, inquisitor, and they have received the kind of harsh treatment I spared you. I tell you this not as a threat, but to acknowledge I could have had you tortured at any time, but there was no point. You will not break, not here, not now.’

Pranix remained silent. Anto leaned in to the inquisitor, who did not flinch. The front of the Red Corsair’s hood wafted in and out with his breath.

‘Think ahead, inquisitor,’ said Anto in a whisper. ‘This facility will soon be evacuated, and I will have you shipped in a sealed and warded life-sustaining container, out to the Red Corsairs fleet. When we have finished our campaign here, you will be transported to the Maelstrom, a place of unending Chaos. How long do you see your will holding out then, inquisitor, in a place that rots the mind of holy men such as yourself? How long until the influence of your environment corrupts you utterly, turns you to our cause without me even needing to ask for your assistance?

‘Take the long view, inquisitor, and you will see that there is no point in resistance. You would be better served by transferring your allegiances to our cause now, renouncing your previous faith and accepting the inevitable on your own terms. That way, you may still hold some control over your destiny, and your assistance in defeating your former armies will earn you a place as loyal servant.’

It was Pranix’s turn to laugh, but it came out desperate and forced.

‘It’s a long way to the Maelstrom, traitor,’ said Pranix. ‘And your great victory is far from assured.’

Anto shrugged. ‘As you say, inquisitor,’ he said. ‘But while you have sat imprisoned, Huron Blackheart has already seized the Orrery and shattered one of the Hollow Worlds, dealing a blow to your forces in the process. We stand close to victory. Your loyalty to me now would assist that victory, and be to my credit in our master’s eyes, but in the long run that matters little. There will be other campaigns, and your knowledge, the precious secrets of an inquisitor, will help us then, whether dropped from the lips of a drooling madman or spoken by a true servant of Huron Blackheart. Through allegiance or mania, you will become ours.’

Anto walked to the door, and banged on it twice with his fist.

‘Enjoy your journey, inquisitor,’ said Anto. ‘The same wards that prevent you or I using our witchcraft in here have been applied to your transport capsule, so I’m afraid there is no hope of escape en route. When I see you again, these Hollow Worlds will already have been lost to you, and with them the last of your hopes.’

The door opened.

‘Tell me,’ said Pranix. ‘When I do escape, and I lead my forces to crush your master and his treacherous filth, what will he do to you when he finds out you lied to him about my death?’

It was Anto’s turn to be silent.

‘You’re a fool for not killing me already,’ sneered Pranix. ‘And too proud to do the deed now and give up your egotistical hopes of breaking me.’

Anto wordlessly passed through the door and slammed it behind him, but Pranix kept talking, then shouting, so that Anto might continue to hear him:

‘I may be in the cell, but it is you who is trapped, heretic.’

Twenty-Four

Rotaka couldn’t feel the skull fragment in his hand. His gauntlets were armoured, and had virtually no sensitivity to the subtleties of the surface beneath his fingertips, the organic unevenness of bone, the coldness of the metallic treatment it had been given when turned into a servo-skull, the dryness of the bloodstains.

Nonetheless, Rotaka sat fully armoured, his back to the wall of the facility on Kerresh, rubbing the piece of bone between thumb and forefinger. A fragment of Iltz, the comrade he had killed long ago, retrieved from the shattered face of Malinko, another comrade killed before his eyes.

The death toll for the Red Corsairs might have been far worse if Kolsh hadn’t followed the Tyrant’s scent all the way to the Orrery chamber.

It had still been a fiercely fought battle, but the Space Wolves were undermined both by the death of their leader and the disappearance of the underground Archway they had used to reach Karstveil, removed by Huron’s adjustment to the Orrery. When the Space Wolves attempted a strategic retreat before making their next attack, they found themselves trapped instead.

As Lord Huron adjusted the Orrery to his satisfaction, it had been Kolsh, lunatic that he was, who rallied the Red Corsairs to fight back against, and slaughter, the Space Wolves.

Rotaka wished there had been some satisfactory, specific vengeance enacted during this turn of events, that he or Hulpin or Verbin or Wuhrsk had tracked down the rabid Space Wolf who killed Malinko and taken his life in return, but nothing so simple or cathartic occurred: the Space Wolves died in a hail of fire from all directions, and in the aftermath it was impossible to tell who had killed who.

The Space Wolves themselves would have continued their vengeance after the enemy were dead, desecrating the corpses and destroying their symbols, but as a warband of dwindling numbers, the Red Corsairs were allowed no such luxuries: the remains, weapons and armour of the dead Space Wolves were gathered and transferred to the hold of one of the galleons, so that Garreon might extract the gene-seed and the Corsairs’ weaponsmiths might strip and repurpose the dead loyalists’ equipment.

The Red Corsairs’ own dead, including Malinko, were dragged away by slaves at the same time. There was no place for sentimentality, or even a passing moment to honour the fallen, in a warband shaped in Huron Blackheart’s own ruthless image.

When the slaves had gone, Rotaka had held on to the bloodied skull fragment.

It had remained in his hand day and night since. In the long voyage across the oceans of Karstveil, through the Archway they had used to come from Hacasta to its new twin on Kerresh, and here to this facility. As opposed to the harsh resistance that had met them on the journey out, the return trip had been entirely without event.

Usually, under such circumstances, the restless Corsairs would have been sparring, taunting each other, getting into fights and reviving long-dormant feuds between rival squads, but now days passed without any such raucous conflicts. The mood between the Red Corsairs was muted, with the shadow of a greater conflict to come.

As reports of the battle in the Orrery had spread, along with reports back from Kerresh as to the loss of Corsairs left on Hacasta when that world was destroyed, a new spirit of simmering resentment had begun to fester in the ranks.

It was in the nature of the Red Corsairs to serve and to fight and to die, without questioning their orders. Those who had been Astral Claws had changed their allegiance from the Emperor to Lufgt Huron, and had followed Huron when he turned on the Imperium. To die in his name was nothing; it was what Huron Blackheart expected of them, and what they expected of themselves.

And yet…

It was not simply loyalty to a man or an abstract ideal that made Huron Blackheart their leader. Neither was it anything as simple or mortal as fear or intimidation, for all that he wielded those against his followers.

No, it was Huron’s greatness as a leader, a worthiness for that role that bled through his every order and action. Though he had ceased to be Lufgt Huron, he retained that strategic brilliance, his fearless grip of the necessities of command, and a warped shadow of the old charisma that had allowed the Tyrant of Badab to turn his Chapter against everything they had once sworn fealty to.

The Red Corsairs were willing to die, even to face defeat, when following a leader who was bold, brilliant, ambitious – a warrior who sought glory and vengeance in equal measure. Those were qualities an Adeptus Astartes, whether loyalist or traitor, would live and die for.

They were qualities that did not characterise the Huron Blackheart who now led them, and there was a disquiet amongst the Red Corsairs that they were led not by a master strategist, but someone more desperate and irrational, bent on an objective that was not military, but personal.

The Red Corsairs had conquered these worlds, but Huron was destroying them, obliterating Hacasta and leaving Kerresh a dying shell. When they could have been consolidating their power in the outer worlds and defending their conquests against the Space Wolves and their allies, instead Huron was pushing ever onwards with his quest, over-stretching his forces so that they were vulnerable at every point on the map.

Whatever power Huron sought at the centre of the Hollow Worlds, would seizing it even leave his Red Corsairs alive, or would he shatter the entire system with his loyal soldiers in it?

Although he was stricken with doubt as to his loyalty to Huron, Rotaka was unsure what to do. It seemed too late to change allegiance at this stage; he had gone too deep. There was no return to the Imperium for him, and even if it were possible, he had even less faith in their Corpse-Emperor than he had in Huron’s gods.

Neither was there a place for him in the other Traitor Legions he had encountered, warbands led by ancient warriors carrying on arcane feuds that dated back to the time of Horus and other mythical figures.

If they deposed Huron, who would lead them then? Garreon was as close to Huron Blackheart as anyone could be, but would doubtless take the throne without remorse should the Tyrant fall. Taemar would betray anyone for glory. There were others, lieutenants who might seek to lead given the right moment, but Rotaka could not see himself following any of them.

Yet he was unsure if he could still follow Huron. The vision of what Huron Blackheart was becoming still lingered, leaving Rotaka with more reason than most to believe that Huron would sacrifice his entire warband to ensure his own survival.

The only loyalty that retained any meaning for Rotaka was to his squad, his brothers, and they were divided. Verbin missed the old Babab, and would throw his loyalty behind anyone who would seek a more permanent conquest of the Hollow Worlds. Hulpin, however, was a true believer in the Ruinous Powers, and would follow Huron purely because he saw him as their avatar.

Which left Wuhrsk. Wuhrsk was a pragmatist. He would turn to whichever side had the upper hand in a conflict within the Corsairs, and he would trust Rotaka’s judgement.

Rotaka continued to stare at the piece of skull as he rotated it between his fingers. Iltz, the comrade he had struck down in Huron’s name. Which was the greater betrayal of his brothers now, to stay the course with Huron Blackheart, or strike against him before it was too late?

The murmurings in the ranks were that reaching Exultance would be the critical point. The Red Corsairs on Kerresh were gradually being ordered to move to the Threshold Archway, and from Threshold they would move to Exultance, and whatever power was Huron’s final objective.

If there was to be rebellion, it would be before Exultance was reached.

If there was to be a reckoning, it would be on Threshold.

Of all the Hollow Worlds, Threshold was the most… hollow.

It was not a dead world, far from it. All of Valthex’s scans indicated there was life here, animals as well as the wide variety of flora that was clearly visible since they crossed through the new Archway on Kerresh. There were, however, no humans, or any superhumans beyond the party Huron Blackheart had brought with him.

It was a world of thick vegetation and hot, moist air. Valthex did not care about living things, but there was some technical curiosity to the place, to how it had come to be in such a condition.

This was what the Hollow Worlds meant to him, a series of curiosities, of technical problems beyond anything he could truly understand. The fear of knowledge at the Imperium’s heart, the terrified blindness embraced by all followers of the Corpse-Emperor, were anathema to Valthex, and had been long before he followed Huron into the service of Chaos.

He had been rewarded greatly for such service. Whatever damnation he may have subjected himself to was nothing compared to the forbidden knowledge to which he had been given access. In a universe quivering in ignorance, he had been given a unique opportunity to delve deeper into lost sciences and long-forbidden technologies.

Valthex’s insatiable, ruthless desire for further knowledge never ceased, and he never felt he knew enough.

The technology of the Hollow Worlds vexed him. He could manipulate the power sources and inputs to some degree, switching monumental devices such as the Archways on or off, providing or diverting power to them, but he could barely comprehend how they worked. He would have been content to spend the rest of his immortal lifetime here, until the universe itself went cold, stripping apart every piece until he found their secrets. He wished to tarry by the newly born Archway, to work out how such a device could spring from bare ground on two worlds, the stone working itself into existence as if from nowhere.

His master’s ambition did not allow him the luxury of such time.

‘How long will this take, Valthex?’ asked Huron. ‘My galleons seek a course.’

The Tyrant stood by the Archway, the iridescence from the barrier between worlds making him a towering shadow. Valthex had a hololithic projector set up, and as servo-skulls spread out, scanning their environment, a map began to form from the signals the skulls sent back. They had been at work for two days, and had about a third of the world mapped.

‘Not long now,’ replied Valthex. ‘The skulls map not only the environment at ground level, but the sky above, in this case the continents opposite as much as they are visible. When that is complete we’ll have a full image of this world, and more importantly the main power flows. With all other technology dead, the only flows should be to the Archways.’

‘We must move on, to Exultance,’ said Blackheart, a restless energy in him as he paced in the light from the Archway.

Somewhere on Threshold, Huron’s intervention within the Orrery had opened up an access point, presumably akin to the Archway – although a scientific mind such as Valthex’s railed at the idiocy of mere assumption – leading to Exultance. It was that which they sought.

Though no mortals currently lived on Threshold, evidently they once had. The Archway had formed in an anonymous valley on Kerresh, but on the other end it had built itself, or grown itself – the uncertainty niggled at Valthex’s curiosity like an itch – in the centre of a ruined Imperial city.

The abandoned buildings were completely overrun with vegetation, not obviously damaged by conflict. Not a trace of human habitation remained.

What had scoured the population so thoroughly from this world? Valthex did not know, and if Huron knew the history of this world, and how it had become lost to the other Hollow Worlds in the depths of time, he was not telling. More mysteries.

‘We will find Exultance, soon, my lord,’ said Valthex.

And when Huron Blackheart cracked open the heart of the Hollow Worlds for his own purposes, Valthex would be there to seize whatever secrets he could.

Huron’s sense of urgency was motivated by the fact that somewhere on Threshold there would be an Archway connecting to Trincul. While reconnecting the flows of power from Exultance to the other worlds, Huron had needed to balance the system by connecting Threshold to Trincul as well as Kerresh, or else the loss of Hacasta would have destabilised the Hollow Worlds entirely. For all of Huron’s callous disregard for life, he prized his own more than anything, and that rebalancing was a necessary evil to preserve himself.

The fact that he had been forced to provide a route for his enemies to reach Exultance enraged him, and if there was one thing Huron Blackheart hated more than the failings of his subordinates, it was the possibility that he himself might be capable of error or weakness. To speak of the fact that he had conceded such an opportunity was to court death.

‘Notify me immediately when there is progress, Valthex,’ said Huron, walking back towards the Archway. For a world he had made such effort to seize, the Tyrant showed no interest in spending any time there.

Valthex was left in silence with his drones and equipment, and the buzzing of insects.

The facility was exactly as the mortal Badya had described, Anvindr thought as he watched the movements around those buildings from a discreet distance. It had been built against the side of one of the planetary ridges, at a point where the huge metal rail towered over ground level.

The buildings crawled up the side of the ridge, with a platform at the top, next to which a ridge runner had stopped. Anvindr could see figures walking on and off the train. Loading or unloading? It was impossible to tell, although he suspected the Corsairs would not stay on Kerresh for much longer.

Was it the same train Anvindr and his squad had seen pulling away from the factorum, shortly before the Red Corsairs counter-attack at the Archway to Hacasta? It was possible. Anvindr and his pack had been unable to pursue the ridge runner then, instead giving pursuit to the demolition engines as they advanced on the Archway. A rocket had destroyed their vehicle and they had not rejoined their fellow Space Wolves until the battle was over and the Archway destroyed.

If it was the same ridge runner then there was hope. In the aftermath of the battle for the Archway and the destruction of Hacasta, the Archway itself had collapsed, and the Red Corsairs had withdrawn. The Space Wolves had searched the ruins of the station in which Tormodr and Sindri had last been seen, but could not find their bodies in the rubble.

By the time the Space Wolves regathered their forces and raided the factorum that produced the demolition engines, the Red Corsairs had already gone. There, the possible trail of Sindri, Tormodr and their captors had been lost.

Until, possibly, now. Anvindr was close, his hunter’s instinct told him so. Whether Sindri and Tormodr were alive or dead, he was sure they were here.

The evidence suggested they were alive. Badya had also been right about the guard patterns, Red Corsairs patrolling the walkways and stairs that ran up the outside of the building, looking as much inwards as out. A prison guard’s patrol, and for the Corsairs to do it themselves… Only other Space Marines could warrant such security.

There was a concentration of guards at the ground level, and the construction of the building suggested there could be as many floors below ground as above. Anvindr suspected any prisoners would be underground, and hoped it was there that he and his squad would be ordered to strike.

To free his brothers and kill the traitors? The kill-urge rose in Anvindr, and he waited with the impatience of a hungry beast for the order to come.

His wish was soon granted.

Pranix was expecting them to take him away while he slept, perhaps using gas pumped into the cell to deepen his slumber, and to wake within whatever containment coffin Anto had devised for him.

He wasn’t expecting his cell door to be kicked open while he was awake, and as the traitors stormed into the tiny space, he thought for a second that his survival had been discovered by those loyal to Huron Blackheart, and that he was to die after all.

His thought as their bolters were raised in his direction was that at least his death would thwart Anto’s scheme to turn Pranix against the Imperium.

But then the two Corsairs made way for another figure to partially enter the cell. Although he was fully helmed and armoured rather than wearing robes, Pranix recognised Anto from his arrogant posture. The sorcerer raised a staff as he looked at Pranix, and it crackled with psychic energy.

‘Take him,’ Anto ordered the Corsairs. ‘Do not attempt to resist, Pranix. I may have struck away the wards but I can kill you before you have the chance to use your powers.’

Pranix cursed himself as he realised that, as Anto had said, the obstructions to his psychic abilities had been taken away. He hadn’t even noticed, and any opportunity to escape before they took him away had passed.

Then he was being dragged between the two Red Corsairs, his feet barely touching the ground. They pushed through heavy doors and Pranix found himself disoriented as he took a breath – they had passed out of the artificially sustained atmosphere of clean processed air, and into a more toxic environment. Pranix coughed and stumbled, but the Corsairs dragged him onwards.

The building they were in was built at a scale for the mortal humans who resided within the Hollow Worlds, not the Adeptus Astartes, and Pranix’s guards moved awkwardly through the narrow corridors. Pranix’s cell had been below ground, and he was showered in brick dust as he climbed the stairs to the ground level, the pauldrons and elbows of the Red Corsair in front of him scraping mortar from the walls as he squeezed through.

The stairs opened up as they ascended flight after flight, curving back and forth, and Pranix realised they were above ground. He could hear nearby gunfire, shouts and screams, and as they passed slits in the walls, Pranix glanced out and caught a brief glimpse of hulking, silver-grey armoured figures running towards whatever building they were ascending.

The Space Wolves were here. No wonder Anto was evacuating.

‘I’m surprised you’re running away,’ said Pranix, trying to conceal the difficulties he was having speaking while breathing such foul air.

‘Do not waste your time taunting us,’ said Anto, without looking around or breaking his step. ‘We are not like the Space Wolves you associate with – we will not be riled into unfortunate anger by challenges to our valour. We will defeat the Space Wolves on the battlefield of Lord Huron’s choosing, and not before. Until then, we rejoin him.’

Pranix was about to challenge Anto over the fact that Huron had ordered for him to be killed, and that taking him to the Tyrant might be a poor choice, when the Corsairs dragged him out on to a rooftop, adjacent to a platform where a ridge runner awaited.

He was silenced by his first sight of the sky above.

The sun was broken, a blue-grey ball in the sky, casting a pallor over the whole world. Visibility was poor, and the other side of the world could not be seen. From high up on the platform Pranix could see desolation in all directions.

‘Which world are we on?’ blurted Pranix, then regretted his words instantly. To request information was to expose oneself to your captors.

‘Kerresh,’ said Anto, turning to Pranix, and the inquisitor could swear there was amusement creeping into his voice. ‘It has been this way since Lord Huron destroyed Hacasta. Do you see now my master’s power, inquisitor?’

Pranix looked up again. One world destroyed, another broken. The confidence Pranix had maintained throughout his captivity began to seep away under the poisonous glare of that dying sun.

As soon as Tormodr heard gunfire he started to strain at his bonds. He hadn’t seen any of the Red Corsairs who acted as his guards for hours, but if this place, wherever it was, was under attack then they would surely be here soon, to fulfil Garreon’s promise to transport them off-world.

Tormodr didn’t intend to take that trip.

Even as he struggled, Tormodr realised that his burst of defiance was useless. It was not as if the bonds had become easier to break because his desire to escape was now stronger. Willpower could only do so much.

What he needed was opportunity, and that would come when his guards came to move or kill him. Tormodr stopped struggling, conserving his energy, prepared to strike at the first chance he was given. Something slammed into the door, and he prepared himself, tensing.

There were two more blows, and on the last one the door flew open.

Sindri barrelled into the room, unarmoured and holding the girder he had broken the door down with. His body was filthy, covered in cuts and burns, and half his face was a mass of bruises.

‘They let you off lightly, I see,’ grunted Tormodr.

‘Shut up or I’ll leave you in chains,’ said Sindri, but he was already limping towards Tormodr, casting aside the girder.

‘How did you get free?’ asked Tormodr, as Sindri released him from his chains. Tormodr flexed his arms properly for the first time in weeks, feeling the muscles burn.

‘Garreon’s manacles were built for a brute your size,’ said Sindri, slurring slightly, one side of his mouth swollen with bruises. ‘For a Space Wolf of slender build like myself, it was possible to slide out, once the right limbs were dislocated.’

‘Well, you could have done that earlier and saved me some grief,’ Tormodr snarled, but he felt sympathy for Sindri. The Corsairs had clearly been working him over more recently than they had himself.

Sindri flashed a smile on the good side of his face, some of his old personality coming back. ‘I needed to wait for the right moment,’ he said. ‘I can’t help it if these traitors just can’t bear to leave me alone, so inspiring is my company.’

‘Sounds like they’re distracted now,’ said Tormodr, nodding his head to the door, from which the sound of further bolter fire could be heard.

‘Aye,’ said Sindri. ‘Let’s take advantage of the distraction further, and find where these untidy bastards have thrown our armour.’

Together, they began to limp to the door.

Rotaka had a narrow window to do what he needed down in the basement of the facility. The Space Wolves were coming in at ground level on the other side of the building, and while they were far away from the central stairwell now, it wouldn’t be long before they took that, cutting Rotaka off from his route back to the roof and the train that would take them to the Red Corsairs camp by the Threshold gate.

Loathe as he was to be reunited with the Corpsemaster, who had withdrawn there to support Huron some days ago, Rotaka liked the company of Space Wolves even less.

Wuhrsk was at Rotaka’s heels, and they found Verbin and Hulpin waiting for them at the bottom of the stairwell. Although Rotaka had ostensibly been charged with this detail, he had barely been down to the basement since his squad were assigned to guard the prisoners. It didn’t seem necessary for him to be involved; their orders came straight from Garreon.

‘Ready?’ said Rotaka.

‘Command is yours, captain,’ said Hulpin.

So, they retained some respect for his leadership, thought Rotaka, even after everything. That would help.

‘Have you briefed the captain?’ Verbin asked Hulpin, with unusual formality.

‘I’m standing right here,’ said Rotaka, before Hulpin could answer. ‘And I don’t need to be briefed to deal with escaped prisoners.’

Rotaka checked his bolter as he spoke, and before Hulpin or Verbin could hold him back further he spun around the corner into the corridor lined with cells.

He found himself targeting two unarmed, armourless Space Marines.

‘Halt!’ Rotaka shouted, but the larger of the two Space Wolves, the one with all the tattoos, bundled the slimmer one through a side door.

‘They’re out of their cells,’ said Rotaka as the rest of his squad took positions around him. ‘Not going to get far without weapons, though.’

Rotaka made a gesture, and Wuhrsk ran slightly ahead, moving to get line of sight on where the Space Wolves had run.

He was almost in position when a bolter shell hit the wall next to him, showering him with brick fragments as the bolt exploded.

The shot came not from the prisoners, but from fully armoured Space Wolves, storming down the other end of the corridor.

‘Cover Wuhrsk,’ shouted Rotaka, opening fire down the corridor. As the Red Corsairs shot back, one of the Space Wolves took cover in the doorway of the cell one of his brothers had only just vacated. There was irony.

Wuhrsk ran past Rotaka, who was already backing down the corridor after him, firing rapid bursts from his bolter as more Space Wolves came down the far stairwell.

‘To the station,’ snapped Rotaka as he turned back around the corner, and began to run up the stairs he had only just come down. ‘The Space Wolves can have their damn prisoners. I don’t want that sorcerer leaving without us.’

Verbin seemed to be about to say something, but instead threw a very casual salute.

‘Yes, sir,’ he said, before racing up the stairs past Rotaka, followed by Hulpin and Wuhrsk.

Rotaka shook his head and followed.

Anvindr was so busy pursuing the Corsairs that he almost ran straight past Tormodr and Sindri. It was fortunate the Corsairs had already disappeared around a corner, as Anvindr froze in the corridor, staring dumbly into a small room where the two missing Space Wolves from his pack were helping each other back into their power armour, a difficult enough task without kaerls and extremely tricky in such a narrow space.

Anvindr stared for a second at the beaten and bruised Space Wolves, their armour half on, unsure what to say.

Then he threw back his head and laughed. ‘It seems you two are just fine,’ he said. It was a lie – he could see the torment they had been subjected to not just in the fresh scars but in their general demeanour – but a necessary one to get them into action quickly. ‘I don’t know why we even bothered coming to rescue you.’

‘We may look fine,’ snapped back Sindri, and Anvindr winced beneath his helmet to see his arrogant, fine-spoken friend slurring through swollen lips. ‘But these uncouth traitors didn’t leave us our bolters.’

‘Russ’ fangs,’ said Gulbrandr, at Anvindr’s shoulder. ‘They really are alive.’

‘They look like hel, though,’ added Hoenir.

‘Enough,’ said Anvindr. ‘Hoenir, Gulbrandr, with me. Let’s show these traitors what we think of how they’ve treated our brothers.’

‘Thank them for their hospitality,’ croaked Sindri, and next to him Tormodr nodded with a grim smile.

‘Arm yourselves, and follow as soon as you can,’ said Anvindr. ‘You’ve rested enough.’

And with that he started down the corridor, the scent of the traitors in his nostrils, determined to make them pay for what had been done to his pack.

‘Captain Rotaka reports the Space Wolves have released their prisoners,’ shouted a Red Corsair from down the carriage of the ridge runner. ‘Rotaka and his squad are on board, and the Space Wolves are close.’

‘Then let us depart and blow the damn station,’ snarled Anto. ‘Lord Huron awaits.’

Pranix, still squeezed between two towering Corsairs, had regained his breath since entering the environmentally sealed train carriage, and remembered the taunt his shock at Kerresh’s state had made him forget.

‘Won’t Lord Huron be surprised to see me,’ said Pranix. ‘Considering I’m supposed to be dead.’

The train began to move, rapidly accelerating, and there was a distant explosion from behind them as they left.

‘Do not overrate your importance,’ said Anto. ‘No one in our ranks other than my closest allies even knows who you are, and there will be plenty of opportunity once we reach camp to have you packaged and sent away without the Tyrant knowing you are there.’ He pointed out of the window. ‘Look at that sky, inquisitor. Do you really think Huron Blackheart, destroyer of worlds will be interested in whether you are alive or dead? You are below him.’

Anvindr uttered an old Fenrisian curse as the rooftop exploded, nearly throwing him off the edge altogether. He rolled to a halt just short of the edge and fired a few bolter rounds at the departing train, but to no avail.

They had rescued their brothers, as Anvindr had hoped, but the Red Corsairs had denied the Space Wolves the battle they were due.

‘Soon, witches,’ Anvindr said, adjusting his helmet as warning runes gradually settled down on his display. ‘Soon.’

‘Call me old fashioned,’ said Kretschman. ‘But aren’t you supposed to be dead?’

‘Good to see you too,’ replied Kulbard.

Kretschman had been at the edge of a bustling encampment on Trincul when Kulbard found him, and they stood facing each other as a light rain fell. System Governor Cheng, alongside one of the surviving Wolf Lords, had gathered all the forces remaining on the Lightward worlds under one banner, and was leading them to a new Archway that had emerged on Trincul.

Through that Archway, they believed, they would find the traitors, and have some kind of final stand. It was not the most complex of strategies, but following the disasters that had befallen the Hollow Worlds, and the problems of communication that had plagued them since, it seemed to be the only option.

This drawing together of sixty or so Space Wolves, a hundred Tallarns and a couple of hundred Lastrati into one army had, at least, returned Kretschman to the centre of the action, brought back from expeditions on Ressial. The Archway was a day’s march away, and the battles to come should have been Kretschman’s main concern.

Instead, he was talking to a dead man, and finding himself enraged rather than scared or pleased to see Kulbard in the flesh.

‘I’m serious, Kulbard,’ said Kretschman, jabbing a finger at the other man’s chest. ‘I left you stranded on Laghast, didn’t hear from you again. I was sent away from the regiment, and now they’re all dead, as far as we know, massacred by traitors.’

He stepped back from Kulbard, boots sploshing through the mud, glaring at the other man.

‘How do you think I survived?’ Kulbard asked.

‘This is not a game or a bloody joke,’ snapped Kretschman, though his anger was waning now, as he could think of several legitimate ways Kulbard got to Trincul. ‘I know why I’m alive – I got shunted off the front line, but why you?’

‘Very well,’ said Kulbard. ‘I’m a scout, I scouted. I slipped through the Archway from Laghast after it was reopened, and I’ve been making my way around here since then, reporting in when I could. Direct reports to the system governor and the inquisitor, thanks to their little birds. They wanted me back here, so here I came. I got off Hacasta before it blew, and here I am. I just reported in.’

‘What did they want with you?’ asked Kretschman.

‘That’s an ironic question for you to ask, Kretschman,’ said Kulbard. ‘You seem to be the golden boy they keep hanging around.’

‘Well,’ said Kretschman, his anger completely drained now. ‘On that, your guess is as good as mine.’

‘Having had some communication with your inquisitor, I’d say it’s hard to judge what is going on in a mind like that,’ said Kulbard. Throughout his exchange with Kretschman the scout had maintained his customary wry smile.

‘Not that it matters now,’ said Kretschman. ‘Without Pranix, we’ve Space Wolves to lead us now, and they’re nothing if not direct. An all-out strike on the enemy on Threshold, everything we’ve got. Space Wolves, Tallarns, Lastrati…’

‘And us,’ added Kulbard.

Kretschman looked up in surprise.

‘You’re not sitting this one out?’ he asked, then regretted the question. It suggested that Kulbard feared combat situations, a grave insult to any Cadian. Even though Kretschman felt uneasy that he and Kulbard had survived where the others had not, it was unfair of him to suggest any lack of valour on Kulbard’s part.

Characteristically, Kulbard did not take offence.

‘I will not be on the front line, but this conflict is coming to an end now, and my eyes are needed on the ground,’ said Kulbard. ‘I’ll be near, don’t you worry.’

‘It’s good to know,’ said Kretschman. ‘I fear that we’ll need every last fighting man and woman out there. Perhaps we will meet on the battlefield at last, after so many of these encounters behind the lines?’

‘Perhaps we will,’ said Kulbard, walking away. ‘Until then…’

He trailed off, giving Kretschman a loose salute, and walked away, disappearing into the mist.

‘You seem distracted, Anto,’ said Pranix. ‘Afraid the destroyer of worlds might not be impressed with your performance so far?’

Pranix had stayed utterly still for several minutes, only moving side to side with the motion of the train, and gradually his guards had unconsciously relaxed. They were still watching him intently, their bolters ready to be raised at a second’s notice, but they had left some space between themselves and their prisoner in the spacious interior of the train.

Others might consider it counter-intuitive for Pranix to draw Anto’s attention to him when it was already elsewhere, but the alternative was silence. For what he was about to attempt, Pranix needed to play with the attention of his captors, to knock it back and forth between himself and Anto.

Pranix was a short distance from the set of double doors by which they had entered the train carriage, but one of his guards was between him and that escape route. Beyond, there was nothing but the distant horizon, which suggested a sheer drop outside.

The situation was less than ideal, but Pranix could not afford to be taken too far away from the Space Wolves and into Red Corsairs territory. He needed to rejoin the forces of the Imperium, whatever the risk.

‘I appreciate your concern, inquisitor,’ Anto was saying, bile dripping from every syllable. ‘But you would be surprised how many tasks I can manage at once.’

‘Impressive, and fortunate,’ said Pranix. ‘I wouldn’t want your mind to wander so much you let me escape.’

Then he ducked sideways, away from the grasp of the Red Corsair observing him most closely. That Corsair lunged for him, a gauntleted hand descending quickly and instinctively.

Instead of jerking away from the grasp, Pranix let himself drop out of reach, and rolled head first between the Corsair’s legs towards the outer door, coming to a stop next to a battered wooden box covered in official warnings that was fixed to the wall. Pranix rolled upwards, opened the case, and grabbed both of the gun-shaped objects hanging on hooks within, rising to his feet holding one in each hand.

Anto, his hand still to the side of his helmet, screamed for someone to find and activate the alarm. Then he looked at Pranix, who was backed up against the outer wall of the train, two guns raised.

‘Emergency flare pistols, inquisitor?’ said Anto, with audible irritation. This mortal was wasting his time. ‘Really?’

‘Against you?’ said Pranix. ‘No, not really.’

The inquisitor tucked one of the pistols into his belt. Then he pointed the other at the safety lock on the train’s outer door, and fired at point-blank range.

The carriage filled with red smoke as the flare exploded against the lock, burning it off. Pranix levered the double doors open and jumped out through the cloud of smoke, into the unknown.

Anto ran to the door, looking out. The rush of air out of the sealed carriage had cleared the smoke quickly, but Pranix was nowhere to be seen. Anto looked back down the train, and down at the ridge the train was running on. The ridge gave way to a sheer drop of considerable distance.

Wherever precisely the inquisitor had fallen, it would have been fatal. Clearly, he had chosen death over capture.

This was a blow to Anto’s long-term plans. Stripping an inquisitor of his knowledge could have provided considerable advantage.

There was no time for regrets, he thought, as Red Corsairs loyal to him levered the doors shut. Lord Huron awaited, and Anto intended to be with him on every step of the journey to come, seeking out the secrets of these Hollow Worlds.

The inquisitor was dead. That was the end of it.

Twenty-Five

Pranix fell.

Inquisitors had tremendous power, and were regarded with almost mythical awe by the few mortals within the Imperium who knew of their existence. But for all their psychic powers, honed combat skills, extended lifespans, fine minds and physical enhancements, they were not Adeptus Astartes. They were not that close to godhood.

Drop an inquisitor a considerable distance onto bare rock, for example, and they would die as instantly and permanently as any normal mortal.

As Pranix fell from the ridge runner, dropping down the sheer side of the ridge towards a rocky slope that led down to level ground, he had a handful of seconds in which to work out how not to die.

His psychic powers had returned to him since being released from his cell, and although he had not used them during captivity, he now had great incentive to re-establish his mastery of one of the talents very, very quickly.

Telekinesis. It had never been his strongest suit, and he found wielding it with precision difficult, but this was not a situation that required subtlety.

As he fell, Pranix willed a contained ball of telekinetic energy into existence a short distance ahead of him, in the rapidly closing space between himself and a rocky death. He strained his mind, pushing as much psychic energy as possible into the telekinetic wave, while also squeezing it tighter and tighter, until the air in front of him was boiling with white-hot psychic energy, to the extent that he almost couldn’t see the approaching ground.

Almost. As impact loomed, Pranix released his hold on the telekinetic power he had created.

The release of telekinetic pressure spread out in all directions, knocking rocks down the slope that led to flatter ground, pushing the air out of the way and buffeting Pranix upwards, killing the speed of his descent and throwing him back into the air.

Winded by his own telekinetic attack, Pranix was batted into the air at an angle, and his bruised body began to tumble downwards towards a lower point on the slope. He had lost most of that fatal momentum, but was still falling towards rocky ground at a speed that could easily break bones.

The inquisitor’s mind felt almost as exhausted as his battered body, but he made one final effort to create a telekinetic field again. This time, he didn’t need nearly as much power, instead drawing a simple cocoon of telekinetic energy around himself, a basic shielding technique that could be used to slow thrown objects or even, with sufficient power, bullets and bolter shells.

In this case, it allowed Pranix to rebound off the slope without smashing his limbs to pieces, his telekinetic shell deflecting him from the ground.

He bounced a few more times, and as the slope got shallower Pranix built up tension in the telekinetic barrier, gripping the ground a little closer each time, until he rolled to a stop at the bottom.

Exhausted, he let himself fall to the ground in a heap. Small stones scratched his face and bare hands as he lay there, but the tiny cuts only proved he was still alive.

Breathing deep of the poisonous air outside the contained environment he had been imprisoned in, he realised he might not remain alive for long if he wasn’t found by someone, quickly.

Rolling onto his back, Pranix drew the second of the two flare guns he had seized on board the train, and fired it into the air.

Now he just needed to let someone know that the flare was significant.

He closed his eyes, and reached out, searching for any mind familiar to him, even slightly, and pushed a simple, one-word message out.

Then he passed out.

Anvindr was still on the rooftop when it happened. The loyalist forces storming through the facility had naturally followed the path of the Red Corsairs who had escaped via the ridge, and so had emerged to find their enemies gone, leaving a platform full of burning debris.

As was often the case in the aftermath of a battle that had very suddenly ended, the victors, if that was what they were, were left just standing, shocked, ready for conflict but with no one to fight. Space Wolves, Lastrati, the Tallarn Badya, all looking at each other unsure what to do next.

That was when it happened. It did not affect the Space Wolves, but it affected half a dozen mortals on the rooftop.

‘Pranix!’ they all shouted, simultaneously, their right arms spinning around to point into the distance, down the ridge in the direction the Red Corsairs had escaped.

Anvindr’s gaze followed their pointing arms, and he saw a red smoke flare exploding in the sky in the distance.

‘Blood of Russ,’ said Anvindr in disbelief. ‘This must be some great joke of the universe.’

But even as he spoke, Anvindr was calculating how far away the flare was, and how long it would take to effect the rescue he now knew was required.

‘Yet again, lord inquisitor, your life falls into my hands,’ said a voice in a low growl, drawing Pranix back to consciousness. ‘There is a wyrd at work here, but I am unsure whether it is drawing you towards your thread’s end or not.’

‘And to think some consider your kind savages, Godrichsson,’ croaked Pranix. He kept his eyes closed. ‘When you have such a talent for poetry.’

Pranix’s eyes and mouth were covered by a rebreather, but he could feel Anvindr’s hot breath near his face, the Space Wolf’s voice close to his ear.

‘Do not mock me, inquisitor,’ snarled Anvindr. ‘Last time it was my jarl, Haakan, who stayed my hand. Now he and his pacifying words are gone.’

Pranix opened his eyes. Anvindr seemed older than he had before, a matter of mere weeks ago, what should have been a blink compared to the many decades between their first and second encounter. He recognised the grief that aged the Space Wolf – it was of a kind that he had seen in Hrondir’s tomb.

‘Yet you stay your hand, even though he is gone,’ said Pranix. ‘For that, I am grateful.’

‘My jarl is dead,’ said Anvindr, leaning away from Pranix. ‘Yet the strength of his words stays with me, and makes me think to what he would say now, were he here.’

‘Which would be?’ asked Pranix. He forced himself to sit up. They were in some kind of medicae tent, a temporary encampment. ‘I ask sincerely – I sought your jarl’s opinion many times, and sorely miss it now.’

‘He would say that you and I fought a common cause long ago, and were victorious,’ said Anvindr, his head scraping the fabric of the tent as he stood up, towering over Pranix. ‘And that if there is a wyrd drawing us together again, then it is because we will need to fight side by side once more. And that is why I haven’t killed you… my lord.’

‘I’ll take that,’ said Pranix. ‘How long was I unconscious? And where are we?’

‘Less than a day, my lord inquisitor,’ said Anvindr. ‘And we move for the Threshold Archway, to pursue the enemy to that world. Our remaining forces from Ressial will join us there.’

‘Threshold?’ asked Pranix.

‘Much has changed in your absence,’ said Anvindr. There was a formality to his manner now that was distinctly unlike the Space Wolves, almost mocking Pranix through excessive respect.

‘Evidently,’ said Pranix.

Anvindr was still standing over the inquisitor, his face a mask, utterly blank. Pranix looked up at him, eyebrow raised.

‘This is your army, my lord,’ said Anvindr. ‘We await your orders, now you are awake. When we break camp, should we proceed to Threshold, or do you have new orders for us?’

‘We proceed to Threshold,’ said Pranix. ‘Whatever this “wyrd” between us is, it seems to lead there, don’t you think?’

Anvindr did not answer, but gave a formal nod and left the tent, leaving Pranix alone to recover.

Hacking his way through the jungles of Threshold, Valthex wished fervently that he had the capacity to bomb the whole area with flaming promethium, razing every living thing and leaving only the hardiest structures standing.

If that had been an option, he could have found this third Archway, or whatever it was, days ago. Instead, without orbital telemetry and with heavy forestation obscuring everything, he had been required to painfully map the planet with servo-skulls.

Eventually, he had obtained the information he needed. Three power flows ran from Threshold’s sun down to the surface of the planet. One connected directly to the Archway from Kerresh, through which Valthex had reached Threshold in the first place. Another led to a second Archway, presumably the one Huron had created to balance the Hollow Worlds, and which led to Trincul. Life signs were accumulating in the area around that Archway, which could mean loyalist forces of the Imperium were beginning to step out onto Threshold with the intent of stopping the Red Corsairs reaching Exultance.

The third power stream led to the geographical position Valthex was slowly approaching. While the other two were, from the correct angle, visible, solid columns of energy connecting those Archways to the sun, this third power flow was stuttering, weak and invisible to the naked eye. Only now, getting close, could Valthex see that energy by adjusting his optics to certain spectra. It was more like a shower than a flow, interweaving lines of energy that appeared and disappeared, trailing between the sun and whatever lay ahead.

Huron Blackheart had sent Valthex ahead so the Techmarine, along with a support squad of Red Corsairs and a host of mindless servitors, were cutting through the jungle in the crudest manner possible, taking a direct route. Huron and his galleons would follow a more practical path through the jungle by which his forces could reach their destination.

Valthex was used to applying his intellect to problems, and having the full technological strength of his warband at his disposal when in battle. While the simple manual task of sweeping a long-bladed machete back and forth, stomping vines under foot with his boots, did not fatigue him physically, he found it deadeningly tedious, repetitive and inefficient.

When he reached the clearing, it was with some relief that the boredom of the long march was over. Valthex tossed the machete aside as he emerged from the jungle’s edge. What he saw ahead of him wasn’t an Archway, or anything that resembled a portal or a doorway.

It was a lake, a wide expanse of dark water. In spite of the ambient temperature no insects hovered on the surface, no weeds or algae gathered in the depths.

Valthex waded through waist-high grass to get to the water’s edge. Through his helmet scanners he could see that the energy flow was hitting the water in the very centre of the lake, and this close it was having a physical effect, causing unnatural, overlapping waves to ripple across the lake’s surface, rising and falling in patterns that made no conventional sense.

There was something else, a low hum in the air, coming not from the centre of the lake, but closer. By the lakeside were great lumps covered with leafy vines and moss. Valthex walked over to the nearest, digging his fingers into the vegetation and ripping it away.

Beneath there was stone, old stone, but old stone that vibrated slightly, with patterns and channels similar to the markings that Valthex had seen on the Archways. Looking around the lake, he could see dozens of similar plant-covered blocks, a ring of ancient machinery surrounding the lake.

‘Find the rest of these,’ he told the servitors and the Red Corsairs, pointing to the… console, the stone before him. ‘Find them all, get them cleared up.’

As they got to work, Valthex stared down at the ancient machine before him, then looked again at the disturbance at the centre of the lake.

Huron was coming, expecting to be able to walk through to another world. The gateway was here. Valthex just needed to open it.

It was almost impossible, but he had dealt with worse odds.

Out of each other’s sight, the forces loyal to the Imperium and those loyal to Huron Blackheart and the Ruinous Powers he served moved across the Hollow Worlds, lines drifting closer to each other across the days, but the forces never meeting.

Both sides were slowly moving towards the same place, even if they did not know it. A single location on the world of Threshold, where Valthex and his servitors worked through days and nights to open a gateway to Exultance.

Many of the Red Corsairs passed through to Threshold expecting to take part in an insurrection, only to find the target of their ire absent. Huron Blackheart had moved many of his troops through the jungle to a new location, some kind of Archway that would lead them to Exultance. The word in the ranks was that it was at Garreon’s suggestion that Huron staggered his army, leading an initial expedition, while the rest followed in clusters so that there could be some rearguard defence if required.

This was typical Garreon, to Rotaka’s mind. To the factions within the Corsairs, it was open to interpretation.

On the one hand, breaking up Huron’s forces at this stage kept potential conspirators separate, limiting their ability to conspire.

On the other hand, potential rebels were being allowed to operate away from the Tyrant’s eyes for an extended period, which enabled them to prepare their coup.

It was a political masterstroke. Whatever the resolution, the Corpsemaster’s suggestion could be interpreted as favouring the victor.

Garreon himself had travelled with Huron, while Rotaka and his squad were part of a contingent including the sorcerer Anto and his cabal, as well as Taemar and a handful of other squads.

It seemed a small number, but Rotaka realised it made up a significant percentage of the Red Corsairs as a whole. It had been Huron who, in a previous life, had rebelled against the Imperium’s restrictions on Chapter size and started experimenting with the Astral Claws gene-seed, an act that had eventually led to the Badab War and their banishment.

Yet here they were, traitors all, unbound by the rules and codices of the Imperium, and still their numbers were dwindling. For all their costs, the heresies of Huron and the Tiger Claws had been for nothing. In exile they were closer to extinction than ever.

Two nights out from the Kerresh Archway, they made camp. Reports back from the forward party indicated that whatever means Huron intended to use to reach Exultance were not available yet, and so there was little urgency required. The trail made by the galleons as they broke through the jungle would still be there to follow tomorrow.

Rotaka sat by a fire, the surviving members of his squad facing him across the flames, and in that moment wished that they had kept marching. The Red Corsairs were hardly inclined to small talk anyway, but now any conversation beyond issuing and receiving orders or exchanging straightforward intelligence seemed freighted with dangerous meaning.

‘Well,’ said Verbin, after one exceptionally long silence. ‘This is exciting. I’m glad we came.’

‘Imbecile,’ snapped Hulpin. ‘There is purpose in the silence before battle, to prepare for the conflict to come.’

‘I hope it comes soon,’ said Verbin. ‘I’m not sure how long I can take the excitement of any more empty jungle.’

‘It will come when the gods see fit,’ said Hulpin. ‘We trust in them, and Lord Huron.’

‘Speak for yourself,’ said Verbin.

Hulpin looked up. Helmless, his eyes were hidden in shadow. ‘What does that mean?’ he asked.

Rotaka should have seen this coming. Hulpin was a zealot, and would never notice the rebellious overtones amongst the Red Corsairs, as to Hulpin such impulses were unthinkable. Now would be a dangerous time for him to gain awareness.

‘He meant nothing,’ Wuhrsk interjected before either Rotaka or Verbin could speak. ‘He never does, but the words still come nonetheless.’

Verbin threw a rock at Wuhrsk in response, and Hulpin couldn’t help but laugh.

Rotaka relaxed a little. This mockery was safer territory.

Then Kruvan approached, and Rotaka’s mood fell once more. He knew Kruvan from the old days, long before Rotaka led this squad. Kruvan had become an Astral Claw around the same time as Rotaka and Iltz.

Who else would they send?

‘Rotaka,’ said Kruvan. ‘I would have words with you.’

Rotaka left his squad behind, their laughter and howls of outraged offence echoing through the jungle as he and Kruvan crunched through tendrils and pushed aside branches to reach a clearing where they could speak with some privacy.

‘Who sent you?’ asked Rotaka.

‘There are many of us…’ said Kruvan.

‘There often are. But who leads?’ asked Rotaka.

‘We stand with Taemar,’ said Kruvan. ‘Should the day come.’

‘What day?’ asked Rotaka, momentarily leaving aside the issue of Taemar’s suitability to lead anything. Rotaka wouldn’t be coaxed into revealing any signs of treachery first, lest this be some loyalty trap set by Garreon to weed out any pockets of rebellion.

Kruvan prowled the small clearing, restless. ‘Some of us believe that the enterprise we are engaged in is a dangerous one,’ he said, with a delicacy of speech that didn’t come naturally.

Rotaka laughed a hollow laugh.

Kruvan looked frustrated. ‘Not danger in terms of death or injury, nothing so banal,’ he said. ‘Danger of extinction, the possibility that our current course will involve the destruction of the Hollow Worlds with all of us in them, as part of a pact with some daemonic power.’

Something like that, thought Rotaka. Neither Taemar nor Kruvan, nor their allies, seemed to be aware of the instability in Huron that Rotaka had witnessed, the growing daemonic presence that threatened to overwhelm the Tyrant.

‘And what do you intend to do about this failure of leadership?’ asked Rotaka. ‘Very little, if you’re too scared to even mention his name.’

They stared at each other for a while. Both were helmless, but the light was dim in the clearing, and the impassive features of a Space Marine were hard to read at the best of times.

‘Huron Blackheart must die,’ said Kruvan, holding Rotaka’s gaze. ‘We could seek to cripple him beyond the point where he is a threat, but we both know that will be almost impossible. The bastard’s come back from the brink of death too many times. To halt his leadership and remove this threat to us all he will have to die, permanently and irrevocably. It is the only way to save our warband and avert this doom, before all we have fought for is lost.’

‘Why come to me with this treachery?’ asked Rotaka. ‘My loyalty to Lord Huron has never been questioned.’

‘That is why we come to you,’ said Kruvan. ‘You think yourself a man apart from your brothers, but we have all known each other for many long years, Rotaka – we watch over each other and even as you stand distant we can tell that you have doubts. If one as loyal as you came to our side, it would mean something to our fellow Corsairs, and persuade them of the worth of our cause.’

He clamped a gauntlet on Rotaka’s pauldron. ‘You struck down one of our own before, Rotaka, back on Badab Primaris,’ said Kruvan. ‘In doing so, you saved us all. If removing Huron can be seen as a similar gesture, a necessary betrayal to save the warband… Well, that will speak to the hearts of the simpler souls amongst us more than the machinations of less-distinguished figures.’

Rotaka shrugged away Kruvan’s grip. ‘So that’s it,’ he said. ‘You need me to provide a loyal face for this enterprise, whereas coming from the likes of Taemar it would be considered simple treachery?’

‘Call it what you want,’ said Kruvan. ‘This is a necessary act for our own survival, and you know it. It is only because you were not there on Kerresh when Hacasta fell that you still harbour lingering doubts.’

Rotaka remained silent, letting Kruvan rage on.

‘Huron Blackheart was willing to destroy us all for some minor tactical advantage, all due to the failure of his own invasion plans. A dozen of us were consumed when Hacasta was destroyed, and if he had considered it necessary Huron would have destroyed Kerresh as well,’ said Kruvan. ‘Think of it, Rotaka – he would have destroyed the Corsairs as surely as Iltz would have destroyed the Astral Claws. You were there when he pressed the button to destroy Hacasta, Rotaka – did he do it in sound mind?’

It wasn’t a button, thought Rotaka, thinking of the Wolf Lord being kicked into the Orrery’s facsimile of Hacasta, an act of violence with planetary consequences.

‘His soundness of mind isn’t our concern,’ said Rotaka. ‘He gives the orders, we follow them. That is the way it has always been.’

Kruvan scoffed. ‘Listen to yourself, Rotaka, talking as if nothing has ever changed,’ he said. ‘Those old rules were torn up when we became Red Corsairs – they were probably rendered irrelevant the moment the old Huron started ignoring orders. Why speak of loyalty when we have rebelled against everything we once stood for? We live by simpler rules now.’

‘Such as?’ asked Rotaka, unnerved by the extent to which Kruvan’s sentiments echoed his own.

‘Survival. Conquest,’ said Kruvan. ‘Taemar may be a reptile, worse still a sorcerer, but he hungers to live, to rule, like so many of us do. Not only will he play a vital role in assassinating Huron, but under his leadership we would be able to seek the glory we desire, fight wars that can be won rather than over-stretching ourselves across a handful of worlds in pursuit of… what? What are we actually doing here, if not to conquer these worlds? What power are we pursuing, and what happens to the rest of us once this power is in Huron’s hands?’

He trailed off, exasperated.

‘I do not know,’ said Rotaka quietly. ‘If you ask if I believe this is the correct course for us… I do not know.’

‘Yes, you do,’ said Kruvan. ‘If you had faith in Huron you would have struck me down. You may not be willing to admit it, but you know that I am right, you know what needs to be done.’

Rotaka began to speak, but Kruvan made a gesture to silence him. ‘You know,’ he repeated. ‘And when the time comes, you will act as required. It will be soon. Will your squad stand with you on this?’

‘One, definitely not,’ said Rotaka. ‘The other two… Yes, I believe they will follow my orders, whatever I decide.’

Kruvan nodded. ‘Then choose well, brother,’ he said. ‘I know you will.’

Kruvan marched back through the jungle, leaving Rotaka alone with his thoughts.

Twenty-Six

While the forces of the Red Corsairs drew together, so did those of their enemies.

They met in the ruined city on Threshold in which the Archway from Kerresh had emerged. In his urgency to reach Exultance with the maximum force at his disposal, Huron Blackheart had abandoned any pretence of securing supply lines or maintaining a hold of key strategic points in his wake.

Instead Anvindr, Pranix and their force of Space Wolves and Tallarns had found little but a handful of dying slaves and cursory, rapidly assembled booby traps at locations previously occupied by the Red Corsairs. The encampments either side of the Archway between Kerresh and Threshold seemed hastily abandoned, as if the closer Huron got to his prize the more frantic he became in his orders.

Inquisitor Pranix was surprised to see such disarray as he walked through the ruined city on Threshold. Huron Blackheart was considered a formidable strategist. What could drive him to such distraction?

Not that Pranix was free from distraction himself. While as an inquisitor he was used to denying himself physical satisfactions, he nonetheless found himself feeling a giddy, near ecstatic sensation at being able to remove the filthy rebreather and heavy protective clothing he’d had to wear while crossing dying Kerresh, to strip down to his padded body armour and the plain, torn robe he wore over the top. To feel the artificial sunlight on his face, and breathe fresh air was sublime luxury.

It was a luxury that he allowed himself for a very short time, because his force needed to hold their position, to wait. While the force under Pranix’s command had been crossing Kerresh, another had been cutting through the jungles of Threshold, moving from a newly formed Archway towards the ruined city. Their movements had been slow, but they would be here soon, and all the forces at Pranix’s disposal would be united.

Soon, he heard them coming, the Rhinos and the other vehicles, and smelt the chemical tang of jungle being destroyed to make way for the new arrivals. They had been in faltering contact via the Space Wolves’ comms since Pranix was rescued by Anvindr, the atmospheric fallout from the destruction of Hacasta and the slow death of Kerresh interfering even with the Space Wolves’ purified communications. It had been enough to arrange a rendezvous, but it left Pranix unsure of the nature of the force approaching, and its leadership.

As such, Pranix was surprised to find Dumas Cheng amongst the leaders of the army that rolled into the city. Pranix would have thought the system governor unlikely to leave the Gatehouse, never mind venture through such dangerous terrain. The old bureaucrat looked thinner, harder, but that could have just been an illusion caused by Cheng wearing Jandarme officer’s uniform – augmented with shining honorary medals, of course – rather than his silken robes of office.

Cheng registered Pranix’s surprise at his presence. Either Pranix was getting slack, unguarded after his captivity and escape, or the system governor was beginning to know him too well.

‘I have lost a whole world to these traitors,’ said Cheng, and Pranix saw then that his first instinct had been correct; Cheng had a new iron to his manner. ‘And have another world left dying. I intend to see this ended, lord inquisitor.’

‘Then I hope you have at least brought a weapon, my Lord Cheng,’ replied Pranix. ‘The Red Corsairs have won virtually every engagement of this campaign, and come back from any blows our forces managed to inflict. We may need every last fighter before this is over.’

‘Speaking of weapons, I have brought you something, inquisitor,’ said Cheng. He disappeared into the throng of gathered officers, and returned shortly with a long object covered in cloth, which he handed to Pranix.

Pranix unwrapped it. It was the staff that he had used as part of his ceremonial trappings when he addressed his forces, and which he had also wielded when he first met Cheng. It was a prop, more than anything, meant to enforce the impression of the all-powerful inquisitor.

‘It was in your quarters in the Gatehouse,’ explained Cheng. ‘Left behind when you were taken. I thought it might be useful.’

‘It’s mainly symbolic,’ said Pranix, weighing the staff in one hand then tossing it to the other. Its shaft was filigreed with silver, skulls and other symbols sculpted in elaborate patterns. ‘Although such items can be used to focus certain energies.’

‘Then maybe it will be useful in the days ahead,’ said Cheng. ‘As you said, we will need any weapon available.’

‘I did say that, didn’t I?’ said Pranix, experimentally swinging the staff in a two-handed grip.

If it came to it, he could probably break someone’s head open with the damn thing.

Around the lake where Valthex worked to gain entry to Exultance, the jungle had been cleared and an encampment had grown. The warband had suffered losses and were spread thin across the Hollow Worlds, with groups securing key points across the system, but still there had gradually amassed seventy or so Corsairs and their supporting mortal troops and servants by the lakeside, restlessly gathered in preparation for whatever lay on Exultance. Rotaka knew that it was more than the mission ahead that kept the ranks quiet, but even those outside the conspiracy seemed subdued.

When the time came, it was Kruvan who broke the silence.

‘Huron Blackheart,’ shouted Kruvan. ‘I would speak to you.’

Rotaka felt the tension ripple through the gathered Corsairs, who had moved towards the stretch of lakeside where Huron spent most of his time. There were no words of support or condemnation from any of the others as Kruvan stood to make the first challenge.

The Tyrant had been berating Valthex about the technological problem the Techmarine had been working on by the lakeside, the manipulation of technology to open up the portal to Exultance, as Rotaka understood it. Garreon had also been nearby, and as Kruvan crossed the encampment, other rebels falling into step behind him, Valthex and Garreon, Huron’s most loyal lieutenants, stepped to each side of the Tyrant, preparing weapons. The sorcerer Anto stood at a slight remove from Huron’s other lieutenants.

‘What must you speak to me of, Kruvan?’ demanded Huron, a sneer on his face. ‘Have you solved the problems that continue to vex loyal Valthex? If so, please share your genius. Otherwise be gone, before you anger me.’

‘You are not fit to lead the Red Corsairs, Huron,’ said Kruvan. ‘Your madness endangers us all.’

As Kruvan faced Huron, looking up at the Tyrant, Rotaka could see Taemar crossing the encampment, axe drawn, Corsairs parting to let him through.

Also, out in that crowd, he could see subtle movements. Where squads were split in loyalties, brother was readying to turn against brother, hands hovering near weapons, ready to draw them when the moment came.

Rotaka looked between Verbin, Hulpin and Wuhrsk. None had moved yet. They were relatively close to Huron and Kruvan’s position, but Verbin was slow to move to support the latter.

As am I, thought Rotaka. Why hesitate now?

Rotaka had expected an outburst of rage from Huron, a characteristic display of bile-spitting mania, perhaps even a sign that his daemonic otherself was manifesting permanently, but instead Huron was silent.

Then the Tyrant laughed a cold, humourless laugh.

Rotaka realised as the Tyrant laughed that he was turned away from where Taemar was moving through the crowd, crackles of psychic energy beginning to crawl across the double blades of his axe.

‘Fit to lead?’ sneered Huron. ‘I do not lead the Red Corsairs.’

He rocked back slightly on his heels, and Rotaka saw a blur again, something changing about Huron, an image of tentacles and countless mouths, ready to burst out into the world.

Huron caught Rotaka’s gaze, and he found the Tyrant’s insane, staring eyes looking straight at him for the slightest second, before Huron turned his attention back to Kruvan and his rebels.

‘I am the Red Corsairs!’ screamed Huron, lunging towards Kruvan, the Tyrant’s Claw swiping through the air. Kruvan dodged the blow but held his ground.

‘Who of you could take my place?’ bellowed Huron. ‘Who would dare to think they could take my warband from me? You live to serve me, Huron Blackheart. There is none amongst you who can challenge me.’

Taemar was nearly upon Huron, raising his axe.

Rotaka could not let this pass. For all his doubts, Huron was right. He was the Red Corsairs. He had led them from the Imperium through hell, and beyond. Without him they were nothing. Rotaka could not let the likes of Taemar betray that.

He began to raise his bolter, only to find a gauntlet holding it down.

‘Have faith,’ said Hulpin simply, holding tightly to keep Rotaka’s weapon motionless. ‘The moment will come, but not now.’

Speechless, Rotaka looked across to Taemar.

Taemar brought his axe around in a wide arc, swinging it past Huron Blackheart, one blade crashing into the chestplate of Kruvan, who was thrown backwards into his own supporters, his chest exploding in psychic fire and fragments of scorched ceramite.

Taemar stood before Huron, and raised his axe high.

‘So die all who defy Huron Blackheart!’ shouted Taemar.

There was a roar of approval from most of the Red Corsairs, a scream of defiance from others, and fighting broke out everywhere. Huron Blackheart charged into the crowd of rebels, sweeping the Tyrant’s Claw down to jam its blades into Kruvan’s exposed torso while lashing out at other dissenters. Garreon and Valthex were right behind him firing on the scattered rebels, while Anto was close behind, unleashing psychic bolts from his staff.

Hulpin let go of Rotaka’s bolter just as Verbin shoved past them, raising a scythed blade, barrelling towards Taemar with fearsome speed.

Taemar had already engaged one of the other rebels, and his back was turned to Verbin.

Rotaka realised in that moment the symbolic value of what Taemar had done, rejecting the insurrection and striking down its mouthpiece. Devious, self-serving bastard that he was, Taemar had nonetheless drawn out the poison of insurrection and suppressed it in one blow. If Taemar was struck down in turn, it would give that rebellion new hope.

That couldn’t be allowed. Rotaka snapped his bolter upright and shot Verbin in the back.

The shot didn’t kill Verbin; it didn’t even wound him. But it did knock him over, causing him to roll forwards, landing on his feet and swinging back to Rotaka.

Verbin pulled off his horned helmet, and spat blood.

‘Will you look me in the eye, my captain,’ said Verbin, ‘and kill me face-to-face as you did Iltz?’

Rotaka pulled his own helmet off.

‘Yes,’ he said, and raised his bolter to fire again.

Before he could even take a shot Verbin was swinging at him with the scythe, but the blade fell when Wuhrsk shot Verbin in the wrist, a precise shot at a weak point in the power armour that left Verbin clutching his hand, fingers limp and useless.

Then Hulpin was in there too, chainfists whirring, slamming into Verbin and bringing him down.

It took all three of them to keep him down, Rotaka, Hulpin and Wuhrsk descending on Verbin with blades and fists, beating him to the ground and keeping him there.

It was Rotaka who dealt the final blow, drawing the long dagger from his belt and slamming it into the back of Verbin’s neck, then twisting it.

He struck the blow without hesitation or mercy for his former brother, his squad mate.

Kruvan had been right, in a way. These things needed to be done.

Rotaka looked up to see similar scenes playing out all around, brother striking down brother, and a slow silence falling across the encampment by the lake. Bloodied and victorious, Huron Blackheart walked past Rotaka, Valthex and his other lieutenants by his side, returning to the stone console they had been arguing over when the insurrection began, short minutes ago.

Rotaka looked at the scattered dead. A quarter of the surviving Red Corsairs, massacred in minutes, only the loyal left standing.

Huron Blackheart turned and opened his mouth, presumably to address the survivors, those loyal to him. It would be a statement of profound arrogance, Rotaka had no doubt, but Rotaka knew that it would also be true, for there was greatness in Huron Blackheart’s madness and egotism, and that was why he stood victorious now while his enemies lay fallen.

Huron didn’t speak. He was looking across the camp, to the edge of the jungle.

Rotaka followed his gaze.

In every direction bar from the lake itself, Space Wolves were emerging from the jungle’s edge. They must have crept up while the Red Corsairs fought amongst themselves.

Rotaka had been involved in brief skirmishes with them so far, but this was a much larger force than the ones he had encountered in the Orrery or on Kerresh. Amongst their number were mortals, some on foot and others riding horses or a type of lizard.

All were heavily armed, hundreds of guns directed at a concentrated group of Red Corsairs.

For a silent moment, the two forces faced each other.

Valthex had experienced the attempted rebellion with a certain detachment, calculating from the first challenge that the odds were against the rebels. It unfolded as he predicted, the numbers never lying. He had killed three of the traitors himself, but it didn’t concern him. They had been comrades for decades, but the statistics were against them. It was simple reality.

Looking around at the massed armies of the Imperium surrounding the lakeside encampment the Red Corsairs had created, Valthex made a similar calculation based on the relative numbers of the two forces, the topography of the area and other governing factors.

This time, the numbers did not work in favour of Valthex’s preferred faction. The Space Wolves and other Imperial forces had the Corsairs surrounded with their backs to the lake, and while the galleons and other heavy weapons were present, they were at the fringes of the encampment or out on the lake itself, and would be little use with the Red Corsairs already trapped in a kill-box by the lakeside.

Amongst the gathered enemies, a figure could be seen wielding a staff crackling with white-hot psychic energy, a figure who, in spite of being dwarfed by the Space Wolves around him, seemed to project his presence across the entire area, so that his voice echoed across the lake.

‘Attack!’ bellowed the man. ‘Show no mercy.’

As the gathered loyalists opened fire, Huron Blackheart turned to the sorcerer Anto, his eyes wide with rage.

‘You told me that inquisitor was dead!’ bellowed Huron Blackheart, and Valthex thought Huron was going to decapitate the sorcerer with one swipe of the Tyrant’s Claw.

‘My lord,’ shouted Rotaka over the exchange of gunfire. ‘They’re pushing us back. They have us surrounded.’

Huron lowered his claw and cursed, ignoring Anto for the moment.

‘Huron Blackheart is never trapped. Valthex,’ screamed Huron, spitting with rage. ‘Open my portal.’

‘My lord,’ said Valthex, shouting over the gunfire. ‘This is technology beyond even my understanding. If we overload it, the consequences could be–’

‘Damn the consequences,’ bellowed Huron, the Tyrant’s Claw gouging into the pauldrons of Valthex’s armour as Huron spun the Techmarine around. Valthex’s helmet display filled with reticules as every weapon he had built into his customised armour automatically targeted the Tyrant at once.

‘Direct all power to the portal,’ said Huron. ‘All of it.’

Valthex could see it now, what the seers and sorcerers had seen but previously he had not, the daemonic side of Huron Blackheart struggling to take him over. Valthex saw it not with any of his vast array of sensors and monitors, but somehow in his tainted soul. Huron Blackheart was losing himself, and with him all would be lost. If Exultance could provide the cure for Huron’s condition, then they needed to reach it, regardless of the risks.

‘All power,’ echoed Valthex. He adjusted the controls to maximum, deactivating every safety control.

For a few seconds, nothing seemed to happen.

Then it began. The air filled with static, sparks flying between metal objects. Valthex lifted one gauntlet to see lightning crackle between his fingers. The ground began to shake, and looking around he observed that the effect stretched as far as the eye could see, Red Corsairs and Space Wolves alike struggling to stay upright as the quake effect spread.

Close to the lake, gravity began to reverse, objects and people lifting off the vibrating ground, drifting upwards. Valthex, having been released by Huron, held on to his control panel as he felt his body lift up into the air.

Under his helmet, Valthex felt his teeth itch.

‘Yes,’ said Huron, elated, his mouth twisted into an insane leer, his feet still anchored to the ground. ‘It is happening.’

Then it struck, a bolt of white-hot energy from Threshold’s sun, discharged right into the centre of the lake. One of the galleons was utterly obliterated, but Huron just laughed, staring right into the column of light, as pure energy flowed down and the water began to boil, twisting into a whirlpool, and at the very heart of the whirlpool was heat, and darkness, and an expanding disc of something turbulent, unformed, a constrained build-up of…

Valthex couldn’t tell what it was, whether it was matter or energy. As he looked at the darkness at the centre of the lake, all the sensors in his helmet were registering the substance he was looking at as unidentifiable.

It didn’t matter. He didn’t know what it was made of, but he knew what it was, its purpose.

It was the portal, a tear in the world, forming in the centre of the lake.

But how to stabilise it? Valthex looked down at his lashed-up controls, but they had burned out. He tore them away to look at the stone machine he had been overriding, but that too seemed fused by the colossal amount of energy running through it.

Whatever was happening, it was beyond his control now.

A great hum filled the air, drowning out even the sounds of combat all around, and then there was… release.

The portal expanded at tremendous speed, like a tidal wave, and Valthex found it hurtling towards him, spreading out in all directions, a liquid energy that was all colours and no colours, and raised his arm instinctively, stupidly, to block it as it flowed over him.

His last thought before the portal, the wave, whatever it was, consumed him whole was that this was the technology he sought; these were the secrets he was looking for, so why wasn’t he more excited about what was to come?

Then he was gone.

They were all gone.

The Red Corsairs, the Space Wolves, the Tallarns, the Lastrati. Their weapons, their vehicles, the ground beneath their feet, the trees around them, the water from the lake. Drained out of existence in a second, leaving a vast crater on the inner surface of Threshold, one which would be visible from the other side of the world, if there had been anyone there to see it.

There wasn’t. Once more, the lost world of Threshold was free of sentient life, left to the birds, the insects and the plants.

And above them all, showing no sign of the fearsome energies it had only just unleashed, the sun turned in the centre of the world.

Twenty-Seven

Anvindr was dead, to begin with.

They had been charging the Red Corsairs line on Threshold, when the world had exploded. Had the lunatic Huron Blackheart found another way to tear apart one of the Hollow Worlds, destroying Threshold as he had Hacasta?

The world ripped away, Anvindr had fallen, and he felt at peace. His thread had been cut and he was tumbling through darkness, but it was not the impenetrable darkness of being buried, of a world without light, but a warmer darkness, like sleep.

Not the immortal sleep he had experienced since becoming a Sky Warrior, but the sleep of his mortal childhood, the darkness found in unconsciousness, buried beneath a pile of furs. The darkness before those times, even, of very earliest life, a distant place removed from the concerns of a bright, cold universe full of dangers.

He was weightless, bodiless, until he was not.

He did not land, but instead found himself standing, walking in mid-step, his boots crunching against a desert of coarse, translucent sand beneath his feet. He was walking through a valley, a dead place with no wind or life.

Although this place was cold, Anvindr had expected the afterlife to be something more like the wild cold of Fenris, a wasteland populated with legendary beasts to slay for eternity and warm caves where heroes could retreat to for ale and food. Here there were no beasts, no halls of glory, no feasts in his honour.

But he was with his pack. Tormodr, Gulbrandr and Hoenir were there, looking dazed upon the sands.

Surely they should be reunited with long-lost Liulfr also? And the other fallen warriors from packs long gone?

Instead, they were alone, stripped even from the army they had run with on Threshold, before the world ended.

Except it hadn’t, had it? Anvindr realised, with something near to disappointment, that he was not dead, not ready for eternity yet. His last winter was not over. The Red Corsairs had been trying to break through to somewhere, to the centre of the Hollow Worlds, and they had succeeded.

He looked up to see that the sky above was the concave surface of another Hollow World, this one smaller than the others. Above, the interior of the world was neither land not sea, but a swirl of shifting plates overlapping and moving, the gaps between them showing glimpses of great machinery beneath. In the sky an artificial sun hung overhead, but its light was harsh and unnatural, its surface patched with tears from which burst ripples of energy that discharged themselves into the land above.

‘Exultance,’ he said aloud. ‘We’re within Exultance.’

Hoenir scooped up a handful of the crystalline sand in the palm of his power fist, and let it drop back to the ground. The individual grains spiralled around each other in an erratic descent. Tormodr let out a low growl watching the sand fall in such a strange way.

Anvindr felt it too. This was an unnatural place, not bearing the taint of Chaos but not part of the natural order either.

‘We need to reach higher ground,’ said Gulbrandr. ‘If we have been transported, then so will others.’

‘Agreed,’ said Anvindr, leading the way up a dune. The crystal sand was compact enough for them to not sink too far, but the Space Wolves still found themselves knee deep in it by the time they reached the top.

‘Great Russ,’ rumbled Tormodr, looking out.

They were on an island a few miles wide, surrounded not by sea but the abstract machinery of Exultance’s interior. A short distance away the desert gave way to a forest of crystal outcroppings that rolled out onto lower ground, and beyond that Anvindr could see rocky hills rising up to a central peak, on which sat a domed fortress of a kind unlike any he had seen before, its curves stretching off and around in ways that blurred his vision. Debris from Threshold – an overturned Corsairs galleon, a pile of broken tree stumps – was scattered across the landscape.

Everything – land, forest, hills, fortress – was illuminated from within. Looking down at himself, Anvindr’s armour and body seemed translucent, glowing.

The rest of the pack were similarly disoriented by this strange place, and it was Gulbrandr, ever alert, who broke the silence.

‘We are not alone, brothers,’ he snarled.

Gulbrandr was right; there was a presence here. Anvindr felt it. But he looked around and could see no one. Of course he couldn’t, he thought, they were further away. Comrades and enemies, they were out there.

Anvindr realised he could feel their presence, and looking to Gulbrandr and the others, he saw that sensation was shared.

They were connected.

‘Are we psykers now?’ asked Hoenir.

‘I bloody hope not,’ said Tormodr. ‘I can stomach some of the priests, but I have no great taste for witchcraft otherwise.’

‘It’s this place,’ said Anvindr. ‘We are at the centre of the Hollow Worlds. The rules are different here.’

‘Is this what Blackheart wanted?’ asked Hoenir.

Anvindr shook his head. ‘No, I don’t think so. That bastard has sorcery already. I’ll wager whatever it is he’s after, it’ll be in there.’

He gestured with his bolter to the domed fortress on the hill. As they all looked up, a bolt of energy crackled down from one of the stars above, and was absorbed by the round building, seemingly absorbed into the… stone? Glass? Crystal?

Whatever it was made of, it drew in power.

Anvindr expected Sindri to make some quip about how obvious a destination the place was, but of course Sindri wasn’t there.

As the thought entered his mind, Anvindr found his mind reaching out to Sindri’s, and while he could not touch the other Space Wolf’s thoughts, he did register his presence, a short march away in the forest ahead, and also the presence of others: dark souls.

‘Red Corsairs,’ Anvindr spat. ‘Sindri’s alone near Corsairs.’

He didn’t even give the order. The entire pack broke into a run, their boots kicking up diamond motes as they went to rescue their brother.

Rotaka had found himself in a clearing of crystal trees, or maybe crystal outcrops, alone.

No, not alone, there was another. A Space Marine of a different colour.

A Space Wolf, one more slender of face than the others, his helmetless head a mass of blond curls. As the Space Wolf stood up, Rotaka saw that it was one of the prisoners they had lost on Kerresh.

Well, thought Rotaka, this is convenient. This Space Wolf might not have been present in the Orrery, but Rotaka would happily take his life in memory of Malinko. Damn Garreon and his schemes, imprisoning these animals.

He raised his bolter in the direction of the Space Wolf, who seemed delirious and lost.

‘Rotaka,’ shouted Hulpin, from somewhere behind him.

Rotaka swung around in annoyance to see Hulpin entering the clearing, gesturing for his captain to follow him, then looked back to where the Space Wolf, alerted to Rotaka’s presence, was moving into cover.

Damn you, Hulpin, thought Rotaka. You’ve startled my prey.

Then he saw the other Space Wolves emerging from the far end of the clearing, weapons raised. Four of them.

So that was what Hulpin was calling him for. The numbers were against them. Even if Wuhrsk still stood, now Verbin was dead – another comrade dead by Rotaka’s hand – and they were no match for a full squad of Space Wolves.

Cursing his poor luck again, Rotaka ran after Hulpin.

Anvindr raised his bolter, targeted the traitor who was fleeing the clearing, and fired.

There was no sound of gunfire, no bolt tearing from the barrel of the bolter to explode in or against the target.

Instead, a bolt slid out of the barrel and fell to the ground.

Anvindr stared in disbelief at his bolter, a noble weapon that had served him, and countless Space Wolves before him, for many centuries. It was as solidly crafted as any in the Imperium, a reliable weapon.

‘Damn you,’ snarled Anvindr. ‘Gulbrandr, take him out.’

Gulbrandr raised his own weapon and fired.

The same thing happened. No sound of a shot. No blaze from the barrel. The bolt rolled out of the barrel and seemed to hover in the air for a second, as if caught in a field of inertia and robbed of its momentum, before tumbling to the dusty ground.

Gulbrandr cursed the distant target, now lost in the treeline, and inspected his own weapon.

‘This isn’t a malfunction,’ he grumbled. ‘This is something else.’

Anvindr picked up the two bolts from the ground, holding them in one gauntleted hand, then stripped off his other gauntlet and touched the tip of his bare finger against them.

Cold. Utterly cold, as if they had been sitting in a rack gathering dust rather than just been fired.

‘It’s this place,’ said Anvindr. ‘Whatever damned witchcraft rules here, it’s affecting our weapons.’

Tormodr, helping the stunned Sindri to his feet, let out a long, weary sigh, clearly about to say something unpleasant.

‘Spit it out,’ said Anvindr.

‘Loathe though I am to admit it,’ grumbled Tormodr. ‘But if this is a matter of witchcraft, we should find the inquisitor. Heresy is his speciality.’

‘I don’t mean to alarm you unduly, inquisitor,’ said System Governor Dumas Cheng. ‘But I do not believe what we are breathing is air. In fact, I am not entirely sure we are breathing, as such. Yet we are alive.’

‘Fascinating,’ said Pranix.

He did not, to Cheng’s ears, sound fascinated. In spite of his commitment to pursue the Red Corsairs wherever they went, regardless of his own fate, to enter Exultance seemed a step too far. No one from the Hollow Worlds had been able to access Exultance for millennia, and there were bleak myths relating to the expeditions sent to explore this world back when the Hollow Worlds were newly settled. With those myths already preying on Cheng’s nerves, the strange feeling in his lungs was pushing him to the edge of panic. But Pranix seemed to have something else on his mind.

‘Inquisitor?’ Cheng asked. They had arrived on a dusty plain that glittered like jewels, beneath a shifting sky of giant layered machinery. They had suffered losses, but still numbered around fifty Space Wolves and a hundred or so mortals, including Cadian infantry and Tallarns mounted on lizards. Cheng could also feel – feel, not see – that the Red Corsairs were here.

As he waited for Pranix to speak, Cheng found his gaze drifting to a hilltop beyond the plain, and the domed building atop it.

‘Not subtle, is it?’ said Pranix. ‘All roads lead there, I expect.’

‘And what is in there?’ asked Cheng.

‘I have no idea,’ said Pranix. ‘All I know is that we need to get there before Huron Blackheart.’

At the rocky ground at the base of the hill, Valthex had adjusted to observing this new world as a mortal might, via the purely optical spectrum. His helmet was fitted with every possible sensor and filter known to man, and many that man had long forgotten, yet they were all scrambled and distorted by the atmosphere of Exultance, and he had needed to switch them off for his own sanity.

Lord Huron and his closest allies, including Valthex, had arrived together. On top of the hill stood a round building of indeterminate scale.

The enemy was sighted shortly after Huron and his retinue had arrived on Exultance, and Becaro fired upon them immediately.

At which point it became clear no firearms or explosives would work here.

‘Curious,’ Valthex said, picking up the fallen bolt. ‘Some kind of inertial dampening field, presumably to protect the inner mechanisms of this artificial star.’

‘Providing the enemy are similarly handicapped,’ said Taemar, wielding his axe, ‘then I am content to take a more direct approach to their termination.’

‘Then you shall be content indeed,’ said Huron, his voice a low rumble, lesser Red Corsairs parting as he stalked between them, his body tense with expectation. He turned to look down on Taemar, and there was a hunger in his eyes that Valthex recognised all too well. This close to his goal, Huron was insatiable.

‘Kill these Space Wolves for me, Taemar,’ said Huron. ‘Gather my Corsairs and slaughter them for me, and defend this hill at all cost. You have my full authority.’

‘You do not wish to lead the attack yourself, my lord?’ asked Taemar.

‘No, Taemar,’ said Huron, staring up at the fortress above. ‘My fate lies elsewhere.’

‘Wake up, Kretschman,’ said a familiar voice. ‘Wake up, damn you.’

Kretschman woke up. He had passed out in the transition from Threshold to… wherever he was now. He forced his eyes open, and saw a blurred face staring down at him. He breathed in sharply, thinking he saw something hideous.

Then the blur resolved, and it was just Kulbard looking down on him.

‘I think I hit my head,’ said Kretschman weakly, closing his eyes again.

‘Never mind that,’ snapped Kulbard, his voice distant now. ‘The inquisitor needs you. Come on.’

Kretschman forced himself upright and opened his eyes again. The glittering world around him made his head ache. Kulbard was gone.

Find the inquisitor? How was he supposed to do that?

To his surprise, he realised he knew how. He could feel where the inquisitor was, and as he stood up uncomfortably, flexing his limbs, Kretschman knew exactly where to start walking, not towards the fortress he could see in the distance, but curving around the hill.

He decided to ignore the environment around him. The rest of the Hollow Worlds had been bad enough, with their seas in the sky. Now this was too much.

Find the inquisitor. Find Pranix. Concentrate on that, with Cadian vigour.

As he walked, then ran across glittering sands, Kretschman realised that as well as Pranix, he could also still feel the presence of Kulbard out there, closer to the round fort.

But in spite of having been standing over him less than a minute ago, Kulbard’s presence was further away than the inquisitor’s, the imprint of his soul distant, somehow.

How was that even possible?

Leaving Taemar to stand guard, Huron summoned his closest advisers to join him in the ascent to the fortress: Valthex, Anto and Garreon.

The technician, the sorcerer and the biologist, masters of the arts that kept Huron Blackheart alive, holders of the secret of the deterioration that had threatened his existence. Valthex walked behind the others as they climbed a narrow path that wound between sharp rock formations, snaking up to the fortress.

‘Anto,’ said Huron as they ascended. ‘Report. And do not think I have forgotten your failure to eliminate the inquisitor.’

‘I regret to inform you that my knowledge of this world is limited,’ admitted Anto, hissing under his helmet. ‘This place… It is beyond my experience. I am gathering intelligence, but nothing of use yet.’

‘I hope your schemes prove more fruitful, Garreon,’ barked Huron, turning his attention to the Corpsemaster.

‘I aim only to serve my lord as best I can,’ said Garreon.

‘No answer,’ said Huron. ‘Are there some secret schemes behind your lack of words, Garreon, or do you simply have nothing to contribute?’

Before Garreon could add anything, Huron turned his attention to Valthex. The Techmarine had known this would come.

‘And you, Valthex?’ asked Huron. ‘Can you tell me any more than these two?’

‘My lord, I have stretched my knowledge beyond its boundaries to manipulate the technology of these Hollow Worlds to get us this far,’ said Valthex. ‘Yet from here on, I can only hope to learn from this place, so that I might serve you better in future.’

‘What of that future can you possibly know, Valthex?’ snapped Huron, spinning around to face his inner circle. ‘What can any of you know? What use will you be when I have the power I seek? What purpose do you serve your lord then?’

Not waiting for an answer, Huron continued his ascent with great strides, leaving Valthex and the others to continue behind him, unsure of their own fates.

As Pranix’s army marched towards the hilltop fortress, they were joined by others scattered by the mysterious forces that had brought them to Exultance. Cheng saw squads of Tallarns riding their red-lizard creatures emerge from valleys, Space Wolves clamber over ridges, even the Cadian Kretschman, all joining Pranix’s force wordlessly, drawn together by the psychic presence that connected them all on Exultance.

Cheng did not hope to understand it, but marched in silence, carrying a silver bolt pistol, a symbol of his office he hadn’t used until the battle on Threshold. He wouldn’t be using it again here, considering the uselessness of firearms on Exultance, but its presence gave him some sense of security.

He was an old man, a leader but a distant one, giving orders from afar, and yet here he was at the centre of his system, discovering that the Hollow Worlds were not as he had understood them. He had grown up in the system, the scion of one of the great families, and he had always taken the nature of the Hollow Worlds for granted, that they were what they called them – worlds.

Within Exultance, Cheng began to see how they could be considered something else. Exultance was as sterile as the inside of a machine, without any plant or insect life, no weather or wind. The features of the landscape that mimicked a normal environment – the diamond deserts and crystal trees – seemed more a mockery of life than anything else.

This system was his home, he was its ruler in the Emperor’s name, but now he felt alienated from the Hollow Worlds, unsure as to whether humans should even live there.

‘Our enemies approach, Lord Huron,’ said Anto as they approached the doorway of the fortress.

‘At last, usable intelligence,’ said Huron. ‘Not that it is of any consequence. Taemar will deal with them.’

The scale and shape of the doorway indicated it was designed for some species other than humanity, towering over even Huron Blackheart, yet also wider than it was long and curved to inhuman dimensions. The door itself was made not of wood, or metal, but an impenetrable blackness as dark as night that filled the space within the door frame. Valthex inwardly cursed his inability to scan the door, left as he was with only his own biological senses to try to interpret this phenomena.

While Valthex and the others hesitated, Huron did not, walking into the solid blackness without even extending a hand before him as he did so. Garreon followed, as did Anto. As Valthex walked through the blackness he experienced a moment’s dislocation, then he was inside.

‘Everything is as I was told,’ said Huron, shortly ahead of them. ‘It is perfect.’

The interior of the fortress was not dissimilar in character to the Orrery, but on a far larger scale. It was almost perfectly spherical, peaking in the dome above and curving down below the semi-transparent floor they stood on. The walls were a burnished gold covered in shifting symbols that moved like oil on glass, ripples of energy constantly passing over them. Around the edge of the chamber were supporting pillars of stone, while at the centre the transparent floor was pierced by a central stone column that reached from the top to the bottom of the sphere. The column glowed with an inner light, crackles of energy running over its surface.

Around that central column floated objects animated by unseen forces, although ‘objects’ did not do them justice. Some seemed to be solid, mechanisms incomprehensible even to Valthex’s knowledge, while others were made of pure energy and looked almost alive. Others were small portals, openings in space through which other worlds could be seen, landscapes of distant places. Flares of energy reached out from the central column to connect with these objects, then dissipated.

Huron walked between these floating anomalies, utterly untroubled, the spheres and squares and slashes that rotated around the fortress simply drifting past him, while Valthex, Garreon and Anto had to weave around them. Having been in the Orrery when Huron cast the Wolf Lord into one of the spheres, Valthex had no desire to be obliterated in the same fashion.

As Huron walked towards the column at the centre of the chamber it opened, blossoming into a thousand suspended fragments of rock sculpted into impossible shapes, revealing an intense light at the core.

‘We are at the heart of a star that feeds suns, the power source for this whole system of worlds,’ said Huron. The intensity of the light was building now, and it seemed as solid as the darkness that they had stepped through to enter this chamber, a physical presence that began to reach towards Huron as he approached, fingers of energy stretching out towards him.

‘Here is the power to fold space in on itself, to forge whole worlds, and to destroy them,’ said Huron, reaching out to meet its touch with the Tyrant’s Claw. The energy wrapped around it, crawling up his arm as he began to step into the growing light.

As Huron was consumed by the light, Valthex could hear Anto chanting his sorcerous incantations, though whether it was in worship or self-defence he couldn’t tell. Garreon for his part was utterly impassive.

There was now only the light with the vaguest hint of Huron’s presence at its core, and around that light spun the shards of the column, the rock glowing from within, sparks flying between each fragment, in and out of the light. Across the chamber, the floating objects and portals and energy shapes became more and more agitated, and the walls of the chamber seemed to stretch outwards, the light coursing through the shifting symbols as they changed at greater speeds. Here, at the centre of the Hollow Worlds, devices beyond even Valthex’s comprehension were coming to life, driven by Huron’s will.

At the centre, Huron Blackheart was barely visible, but his voice was louder, coming from everywhere.

‘This power, it burns,’ boomed Huron from all around. He was the chamber. He was Exultance.

‘And that power is mine.’

Twenty-Eight

Rotaka looked up from his position in the rocky lands at the base of the hill to see the fortress above lit from within. It sounded like a thunderstorm was breaking out in there, but Rotaka was not concerned. He had faith now, and he believed that whatever Huron did with the power he found up there, it was the correct thing to do.

He even had faith in Taemar’s leadership, because Huron did.

What did concern Rotaka was the Red Corsairs’ ability to defend that hilltop fortress from the incoming forces of the Imperium. A significant number of Red Corsairs who rebelled against Huron had been killed on Threshold, leaving less than fifty alive on Exultance, and no squad unbroken by casualties and treachery. Taemar had spread the survivors across the area around the approach to the hilltop fortress, taking cover behind rocky outcrops and lying in wait for their enemies. It was a sound defensive position, the raised ground giving them clear views of the crystal forests and distant deserts. When the enemy emerged, the Corsairs would see them coming.

The Space Wolves, however, in spite of their losses in the Orrery and in the Valley of Blades, were still many in number, and their feral nature would make them more dangerous, not less, when stripped of the ability to use firearms and forced to engage with fist and claw.

‘They are coming through the forest,’ shouted Taemar. ‘Prepare yourselves.’

At least, Rotaka thought, they did not need to cover every approach. Whatever quality of Exultance allowed them to sense the presence of others, it meant that they knew exactly which direction the Space Wolves and their mortal allies would come from.

Rotaka wished he had a full squad under his command, even though he knew now that those sacrifices had been necessary. He looked at Hulpin and Wuhrsk, the former muttering prayers to his gods, the latter simply standing still, waiting.

They were few, but they were united in their loyalty to Huron Blackheart.

That unity would be enough to stop these dogs in their tracks.

There was no point in subterfuge. If Anju and the other loyalists could feel where the Red Corsairs were gathered, then the Corsairs too would be aware of the mass of Space Wolves and mortals coming for them.

‘Let these traitors know who they face today!’ shouted Anvindr as the Space Wolves ran full tilt through the crystal forest. A great howling roar rang out from the Space Wolves, a blood curdling feral war-cry that was so loud Anju almost expected the trees to shatter. Added to that cry were the ragged cheers of Tallarns, Cadians and Lastrati alike, the mortals charging in the wake of the Space Wolves.

The light at the end of the crystal forest approached. Beyond lay the rocky, steadily rising area around the hill and the fort, and the enemy. Not long now.

Sergeant Anju Badya had never ridden into battle without a gun to fire before. She knew that if she fell into hand-to-hand combat with the Corsairs, she would be torn limb from limb.

At least she had Folly. The Tallarns who had travelled to Threshold from the Lightward side of the system, the riders who still had their horses, had looked askance at the bird-lizard things ridden by the mortals who had survived the conflicts on Kerresh, but had ceased any mockery when they saw how the alien mounts efficiently ran at a pace to match the powered vehicles of the Imperium, heading through the jungles on that world.

Here, on Exultance, they all rode together, mortal riders flanking the mass of Space Wolves who marched on foot.

Was this the battle where Badya would be needed, the reason she had survived so long? Folly’s namesake, Folkvar, had thought such an event would come soon.

As they burst from the forest, Sergeant Anju Badya, last survivor of her squad of riders, only loyalist survivor of the battle of the Valley of Blades, a marksman without a gun, just hoped to live long enough to be of some use.

Although both sides knew in their guts where the others were, the Red Corsairs still clung to what little element of surprise they could leverage, waiting in cover to attack the Space Wolves at the last possible moment.

The traitor who burst out of cover behind a boulder, fists raised and swinging a punch straight at Anvindr’s head, only surprised him with the fact that those fists were on fire.

Anvindr dodged the blow, a streak of green flame following the Corsair’s fist as it passed close to his exposed face. The heat of it seared the bristles of his beard, and he felt something worse from that near contact, the corruption of Chaos. He already had his chainsword drawn – while bolters and lasrifles did not work on Exultance, more crude mechanical weapons did – and swung it upwards, thumbing the button to bring the teeth whirring into life.

The Corsair caught the blade in his hands, a move that should have lost him his fingers, but instead contact with the green flame caused the chainsword to seize up, spluttering and smoking as the teeth stopped moving.

‘Weapons cannot harm blessed Becaro,’ the Corsair leered, gripping both sides of the chainsword and pushing it downwards. The green flame was spreading down the blade, and Anvindr could feel the heat through his gauntlets. ‘The gods are with me.’

‘Your gods are nothing,’ growled Anvindr, letting the chainsword fall from his hands and swinging a punch at his attacker. Around them Corsairs and Space Wolves were clashing, the air filling with the noise of metal and ceramite crashing into each other, the roar of battle.

Becaro dropped the chainsword and wove out of the way of Anvindr’s punch, one hand grabbing hold of Anvindr’s wrist, the other lunging for his throat. The green flame had the same paralysing effect on Anvindr’s body as it had on the chainsword, and he felt his airways seize up, the muscles in his neck and arm locking. A searing horror began to burn into him, flames spreading up his face, heat coursing through his body. His left hand struggled to tear Becaro’s iron grip from his throat, but there was an unnatural power to his hold. The green fire was rising over Anvindr’s entire face, blurring his vision as the heat stung his eyes.

‘You see, now,’ hissed Becaro, pulling the struggling Anvindr towards him. ‘My gods are real. Their power is real and pure. It is you who are the heretics.’

Anvindr stopped pulling away and pushed forwards instead, moving with Becaro so that his head slammed into the Corsair’s face. Becaro released his hold on Anvindr, staggering backwards and shaking away the green flame that was now clinging to his own features. His own head still ablaze, Anvindr didn’t stop to put the unnatural fire out, dropping to his knees to seize his fallen chainsword, swinging it around as it sprang back to life.

Becaro’s eyes showed genuine shock at his imminent defeat, just before the chainsword embedded itself in the side of his head.

The flame that burned Anvindr died as its wielder did. His face felt scorched and raw, and Anvindr was sure most of his beard and hair were burned to stubble, but he had no time to tend his wounds, swinging his chainsword around to find his next opponent.

Dumas Cheng had no horse or other mount, and would not have known how to ride one even if he had pulled rank and requisitioned one. In spite of his best efforts to keep pace, he had drifted towards the rear of the marching Space Wolves and mortals. The juvenat treatments over the years had helped him maintain some facade of relative youth, but he was still, beneath it all, an old man.

One accident of drifting to the rear was that, as the Red Corsairs and Space Wolves clashed, Cheng had a wide view of the battle.

He remembered then what Pranix had told him back in the Gatehouse, just before his abduction – that the combat of demigods was an awesome sight, but one too dangerous to get close to.

Denied firearms, the traitors and the Space Wolves clashed with swords, axes, clubs and even their gauntleted fists. The sound was thunderous and the field of battle at the base of the hill echoed with a cacophony of clashing metal as blows were engaged at terrifying speed.

At the periphery of the battle, the mortals did their best. The Tallarn riders rode at a distance, throwing the sharp crystalline rocks they had gathered in their saddlebags, trying to provide some distraction, making the Red Corsairs vulnerable.

It was a brave tactic, but futile. Cheng saw one Red Corsair pluck a thrown rock out of the air, and in one smooth motion throw it back with sufficient force that it caved in the side of the rider’s skull.

On one side of the field, a group of three Corsairs surged forwards, pushing past the Space Wolves briefly, and were met by a dozen Lastrati wielding swords and other weapons. Cheng found himself unable to look as the Corsairs batted aside the Lastrati’s weapons, seizing the arms that held them and tearing those limbs out of their sockets.

No. Cheng forced himself to look, and take in the sacrifice his subjects were making.

Then he raised his ceremonial sword, bellowed an arcane war-cry and charged forwards, so that he too might provide some small resistance to these monsters.

It was Anvindr who saw it. In their eagerness to descend upon the mortals who dared stand against them, the Red Corsairs had pushed forwards too far, spreading themselves too thinly to block all routes to the fortress. In spite of the shouted exhortations from an axe-wielding Corsair to hold the line, that line had been over-extended, and had a weakness.

That weak point would break, and from there the Space Wolves could reach the path up to the fortress.

‘Inquisitor,’ said Anvindr.

Pranix was nearby, encircled by Space Wolves, including Anvindr’s own squad. The inquisitor was not defenceless by any means, unleashing blasts of psychic energy from his staff to drive back any Corsairs who got close to him, but whatever lay at the top of that hill, Pranix was their best hope of stopping it.

At Anvindr’s word, Pranix looked past him, and saw the opening. He nodded to the Space Wolf, and they charged forwards, Anvindr raising his chainblade.

Most of the Space Marines on both sides had abandoned their helmets, as the atmosphere of Exultance had rendered their displays useless. Anvindr swung his chainblade into the face of a helmless Red Corsair, tearing through the traitor’s face, half taking his jaw off.

The Corsair looked up at Anvindr, something close to joy in his eyes, then batted aside the chainsword to slam a chainfist into the Space Wolf’s face, the blades whirring and clicking against Anvindr’s free arm as he blocked the incoming blow.

Then the Corsair was being pulled off Anvindr, Tormodr slamming into the wounded Red Corsair, pulling him over and punching the traitor repeatedly in the face, blood trailing off his gauntleted knuckles.

‘Get the inquisitor to the Tyrant,’ said Tormodr. ‘This traitor was one of my jailers, and I owe him.’

Anvindr nodded, and as Hoenir punched another Corsair aside with his power fist, Anvindr and Gulbrandr flanked Pranix as they began to run up the hill, Sindri close behind them.

As his brothers fought to buy them time, Anvindr didn’t look back.

The Space Wolf who Rotaka had been exchanging blows with was, to Rotaka’s surprise, missing the top half of his head, an axe crackling with psychic energy having swept horizontally through his skull.

The corpse dropped to the ground and Taemar was screaming into Rotaka’s face. ‘The line has been breached, Rotaka!’ he bellowed. ‘We must stop those Space Wolves.’

Rotaka spun around to see the carnage behind him, and took it in with a glimpse, his mind processing what he saw within a second.

A small faction of Space Wolves were moving up the hill, having breached the Corsairs’ line.

Where they had broken through, another Space Wolf was beating Hulpin to death.

Beating Hulpin to death.

Ignoring Taemar’s orders, Rotaka bellowed with incoherent rage and charged at the Space Wolf who was pounding on fallen Hulpin.

Stupid. As Rotaka ran, a red-headed Space Wolf slammed into him with a power fist, cracking his power armour around the ribs and knocking him to the ground. Rotaka rolled over onto his back, and the power fist would have crushed his skull if Taemar’s axe hadn’t intercepted it, shattering it and leaving the red-haired Space Wolf reeling.

‘Leave them to the others,’ said Taemar, dragging Rotaka to his feet. ‘We need to stop those Space Wolves.’

Rotaka looked. Wuhrsk was exchanging blows with the stocky Space Wolf who had downed Hulpin, and other Corsairs were gathering. Meanwhile, the Space Wolves who had broken through the Red Corsairs’ line were heading up the hill at speed, and Rotaka could see the glowing staff of the inquisitor lighting their way.

Taemar was right. Reluctantly, Rotaka left the last survivors of his squad behind, and began to ascend the hill.

Anvindr had the uncanny sensation that he was not moving towards the fortress on top of the hill so much as the hill was moving towards him. His boots felt like they were passing through air, like a dream of flying. Everything seemed unreal.

Even for a Space Wolf, used to living partially in a world of myth, it was disorienting.

‘Whatever Huron Blackheart is doing up there, it’s disturbing the surrounding reality,’ said Pranix. ‘The psychic plane and reality are blurring. We are moving as much through our will to reach that place as we are physically moving.’

‘And what of our pursuers’ will?’ asked Gulbrandr. ‘Do they simply need to want to catch us up?’

Anvindr glanced back to see two Red Corsairs chasing them. Further down, he could see Tormodr and Hoenir encircled by more Corsairs. He wished he could return to assist them, but he knew what was required of him, of Gulbrandr, of Sindri. Their threads were linked to Pranix’s now.

‘I don’t know,’ said Pranix. ‘But our will seems to be holding out for now.’

As a Cadian, Kretschman was used to being in a dominant position in most battles, but on this battlefield, where Space Marines were fighting Space Marines hand-to-hand, he could do little except try not to get killed.

This was no place for mortals. As the immortals fought, the humans barely registered as distractions, and the ground was littered with dead Tallarns and Lastrati who had been idly torn to pieces or knocked aside by the Red Corsairs. What use could he be, on a battlefield like this?

‘Look around,’ said Kulbard, appearing at Kretschman’s shoulder. ‘There must be something you can do.’

Kretschman looked. He saw, past the fighting Space Marines, a trail of figures moving quickly up the hillside, guided by the white-hot flare of Pranix’s psychically charged staff.

‘They need you,’ said Kulbard. ‘Get up there. This is your last chance to prove useful.’

Then he ran off, ducking between the fighting Space Marines, somehow evading them all.

How was Kretschman supposed to follow? It didn’t make sense. Then he saw one of the surviving Tallarns, riding low on one of those red lizard things, and had an idea how he might catch up.

How do you address a god?

Huron Blackheart was at the centre of the chamber, the energy at the centre of the room flowing through him from floor to ceiling. He was incandescent, his body flowing with light. It was neither psychic energy nor the burn of plasma from a cannon, or any conventional energy. It was something else, a boiling essence of creation. Huron had risen from the ground, and was flexing his form as the energy surged through him. Tendrils of energy reached out from the central column, making contact with the portals floating around the room, re-energising them.

Anto had news for Huron, but did not know how to approach his master.

He walked closer to the core, and the psychic part of Anto, his sorcerous ability to see the touch of Chaos with his mind, could see that the daemonic presence that had threatened to overcome Huron Blackheart was being scoured from his being. The flames of this new energy were burning the malady out from the Tyrant’s flesh. Anto had experience enough of pain, but could not understand how the fire coursing through Huron on a cellular level could be tolerable.

Getting closer, he could see more. The energy within Huron wasn’t just cleansing; it was healing. The most recent wound the Tyrant had sustained, the cut beneath his chin where the Wolf Lord had stabbed him, was beginning to seal, something that should not have been a possibility with Huron’s dead, grey flesh. But then, even behind the blinding light, Anto thought he could see a hint of colour returning to that skin, a hint of… life?

Anto felt a lurch of betrayal. Was Huron intending to rid himself not just of daemonic infection, but of Chaos altogether? Could the great traitor be planning to betray Anto’s own gods, just as he betrayed the Imperium? Looking around, Anto spotted the Hamadrya, a creature of Chaos, hissing at the edge of the chamber, spurned. It knew many things even Anto did not about the Ruinous Powers – did it know that the depths of Huron’s ambition would cause him to strike back against the Dark Gods?

As Anto approached, Huron’s gaze turned upon him. The Tyrant looked down, and both his organic and cybernetic eyes were blank spheres of energy, white hot.

‘You wish to address me?’ said Huron, and there was an unfamiliar tone to his voice.

Ecstatic. Beatific. Benevolent.

This lack of malice froze Anto, and he could not resist answering truthfully. ‘Enemies approach, lord,’ he said.

‘Deal with them,’ said Huron, and Anto took some comfort from the venom in the Tyrant’s voice. ‘When I have remade myself, I will remake these worlds, and more beyond. There will be no place for these dogs in my new kingdom.’

Unsure exactly what Huron meant, but definitely sure he did not want to defy him at this time, Anto turned and marched away to carry out his orders.

Hoenir was the first of them to die, which to Tormodr seemed unjust. Like the others of his pack, Tormodr still saw Hoenir as something of a youth, even though they were, all of them, mature in years.

Tormodr couldn’t help but feel it should have been one of the older Space Wolves in the pack who died first, not Hoenir.

As the Corsairs closed in on the two Space Wolves, Hoenir was hampered by his broken power fist, and while wrestling with a Corsair, another embedded an axe illuminated with psychic energy into his skull.

Hoenir collapsed, his head blackened and smoking.

Which left Tormodr. Elsewhere on the battlefield, it was the Space Wolves who outmatched the Corsairs, who were fighting to keep the higher ground, but here Tormodr was surrounded by half a dozen Corsairs with blades and axes and claws.

‘Right then,’ said Tormodr, cricking his neck and raising his fists. ‘Who’s first?’

Anju Badya didn’t know whether this Kretschman was as much of a lunatic as he seemed, but the situation they were in was sufficiently sanity testing that she didn’t feel able to write off anything as being too mad.

So, when he asked her to ride him up the hill on Folly, she pulled him up onto the back of her mount, and tried to steer a course. Over open ground, Folly managed to find a break in the Red Corsairs’ line, heading for a seemingly impassable slope, and began to pick its way up the sharp incline with surprising sure-footedness, despite the additional weight.

‘Follow him,’ said Kretschman. Badya had no idea who he meant, as all she could see were the Space Marines running up the trail a short distance away, but as Folly was picking her own route it didn’t make any difference.

So she just hung on, and hoped things would start to make sense again soon.

Valthex was transfixed by the energy source his master had tapped into. Even without his full sensory apparatus, he could see that Huron was capable of controlling the energy with his consciousness. An energy that could shape worlds.

Garreon was watching too, waiting to see what this new development meant for him, no doubt. Anto had withdrawn to the edge of the chamber.

Lord Huron arched his back, his arms and legs stretching and shaking.

‘No… No…’ boomed Huron Blackheart his voice everywhere within the fortress at once. ‘It is too much.’

He lurched inside the column of light, pushing himself forwards, and he emerged from the core still lit from within, his whole body smoking, dropping to the floor and staggering a few steps before falling to his knees. Valthex rushed forwards and was there to halt his fall.

As Valthex grabbed his master by the shoulder, Garreon running up to do the same from the other side, Valthex felt a white-hot sensation within his gauntlets, radiating right through his power armour. It was not a natural heat, and seemed to heal as it burned. Valthex felt the third finger of his hand, crippled in an accident centuries ago, twitch with life for the first time in years.

‘I will not be defeated by this power,’ snarled Huron, his head still hanging down, his expression hidden and unreadable. ‘I have waited too long.’

He slammed the Tyrant’s Claw against the floor, and a release of energy spread out in all directions, throwing Garreon and Valthex away from him and across the chamber.

Further away, Valthex could see Anto rock to one side but hit a stone column, steadying himself without falling.

Kretschman and the Tallarn sergeant, Badya, were almost at the fortress when the earthquake hit, knocking their mount over and causing them to fall off. Badya managed to cling on to her lizard as they both fell, but Kretschman fell on his side on the ground, hard. Thankfully they had moved beyond the most precarious part of the ascent, and Kretschman landed on flat ground rather than rolling back down the hill.

It was like landing on shattered glass, his uniform cut and his flesh gouged in dozens of places, but at least he didn’t break any bones.

Kretschman had been watching Kulbard all the way up the hill, the scout turning back occasionally to gesture to Kretschman to keep following, and Kretschman kept his eyes on Kulbard as he fell.

When the shock wave hit, Kulbard didn’t fall over. He wavered, steadied himself with an outstretched hand resting on thin air, and righted himself.

‘How did you do that?’ said Kretschman, and although he was too far away for Kulbard to hear, the scout turned.

‘Follow me and find out,’ said Kulbard, his voice close to Kretschman’s ear.

Badya was stunned, rolling on the ground nearby. Kretschman ignored her and, bleeding from countless small wounds from his fall, began to follow his friend to the fortress’ entrance, around the curve of the round building.

At the edge of the chamber, Valthex tried to right himself, but the strange energy that had passed to him was coursing through his body, confusing his senses, and he found he could not stand. He could see that Garreon was similarly stricken a short distance away, while Anto was still leaning against a supporting pillar, seemingly ignoring everything around him.

Which left Huron Blackheart crouched down, the floor beneath him having shattered outwards, cracks spreading from where his knuckles had dug into the floor. Rather than having dissipated, the smoke rising from his body seemed thicker, as if the power was still building within him. His shoulders were tensed with effort.

‘I will not be defeated,’ snarled Huron, pushing himself up on one knee, then using the other leg to force himself to stand. His eyes still glowed white-hot as he turned around to face the column of energy at the centre of the chamber.

‘I will master this power,’ Huron said, stepping towards the core. Each step took effort and focus, as if he were walking into a hurricane.

‘This system will be mine,’ he snarled, throwing himself back into the blazing core.

Anvindr, along with Gulbrandr, Sindri and Inquisitor Pranix, were back on their feet within seconds of the shock wave hitting. The inquisitor led the way, running through a doorway filled with solid darkness without hesitation, and the three Space Wolves followed.

‘Witchcraft,’ said Gulbrandr, taking point and passing between the columns that ringed the very edge of the chamber.

Anvindr saw what he meant. What they were greeted with inside was not the work of Chaos, but it was witchcraft of a kind nonetheless: an open, rounded chamber, filled with floating objects, portals and pools of strange energy. It was unnatural, alien, and Anvindr knew he was in the presence of energies that should not exist. The floor was cracked and two Traitor Marines lay prone at opposite sides of the chamber, but it was the figure within the column of light at the centre who drew all their gazes. Anvindr had never seen the Tyrant before, but there was no mistaking his silhouette, the Tyrant’s Claw and the halo of thorn spikes behind his head. Anvindr could see no more as Huron was ablaze with an unnatural light, his claw flexing convulsively, seemingly wrestling with the energies he was consumed by. He was a thing of raw power now, a creature of light.

‘How do we kill that?’ asked Gulbrandr.

‘You don’t,’ said a slurred, cruel voice, and Anvindr was hit by a bolt of psychic energy that burned through his nerve endings and threw him off his feet. The white-hot tendrils of energy crawled over all of them, and Anvindr slammed into Gulbrandr and Sindri as they, along with Pranix, were knocked across the chamber by the blast.

‘You shall not deny my master’s godhood,’ said the figure who emerged from behind a pillar, a Red Corsairs sorcerer who wore a red cloak over his armour and wielded a notched staff.

At the centre of the chamber, Huron convulsed and bellowed in agony.

‘Godhood really doesn’t seem to suit him, Anto,’ said Pranix, pushing himself up with his staff. Sindri had rolled over him as they fell, and one of the inquisitor’s legs seemed to be broken. He winced with agony as he stood.

‘Besides,’ said the inquisitor, slumping on his staff. ‘Don’t you have at least one god already? Are you committing heresy against your own heresy now?’

Then Pranix let his staff drop forwards slightly, and unleashed a blast of psychic energy of his own. Anto raised his own staff to defend himself, and the two currents of psychic power met with an explosive glare between the inquisitor and the sorcerer.

‘Kill Huron Blackheart,’ Pranix shouted to the Space Wolves over the roar of wild energy. ‘I’ll have this one.’

Anvindr nodded to Pranix and they ran towards the centre of the chamber, dodging the whirling tendrils of energy in the air and ducking under the portals that opened out into other worlds, other spaces, only to be blocked as one of the Red Corsairs who had been prone on the floor stepped into their path.

‘Three against one, traitor,’ said Anvindr, raising his chainsword.

‘Not quite,’ said the Corsair, a thin-faced creature with grey, cruel eyes.

There was a howl of agony from Gulbrandr, and Anvindr turned to see Sindri withdrawing a long, thin blade from the other Space Wolf’s eye socket.

‘I’m sorry, Anvindr,’ said Sindri. ‘But Garreon is remarkably persuasive.’

Kulbard was stuttering like a faulty vid as Kretschman followed him through a doorway of pure night and into the fortress. Inside was a scene that nearly broke Kretschman’s mind altogether, a tableau of sorcerous energies cutting through the air and strange objects floating past. Immediately ahead Kretschman saw Inquisitor Pranix and a Red Corsairs sorcerer in a red robe engaged in some kind of psychic battle, strange energies emanating from their staffs and setting the air ablaze.

The Red Corsairs sorcerer turned to Kretschman as he entered the chamber, Kulbard turning too.

‘There you are, my little toy,’ said the Corsair and Kulbard in unison.

Then Kulbard was gone, as if he had never been there at all, and there was just Anto, because it had always been Anto. And Kretschman remembered, now, being taken away from the fringes of a battle, and the sorcerer looking down on him, and all that being repressed deep, deep, deep…

Then Kretschman’s body exploded in a wave of psychic energy, tearing out of him and blasting Inquisitor Pranix sideways, and Kretschman was falling out of himself as his body burned…

‘Why?’ asked Kretschman. They were in his carriage aboard System Governor Cheng’s private ridge runner, tearing across the dull surface of Trincul.

The figure sitting opposite was Kulbard, and he was not. The figure of Anto was superimposed on him, and it was both Kulbard’s hand and Anto’s huge gauntleted fist that picked up the amasec glass and sipped it, ridiculously in the case of the helmeted Space Marine.

‘You were an experiment,’ said Anto/Kulbard. ‘One of many. A more advanced version of the insektile experiments. But with you the seed was more complex, a sub-personality lurking beneath your own, a sub-personality externalised so that you would appear clean to even a practised psyker.’

‘So Kulbard was just me?’ asked Kretschman.

‘Mostly, yes,’ said Anto/Kulbard, taking another sip. ‘You’re right, this stuff is second rate. Yes, mostly Kulbard was just you, but that sub-personality also had a deeply buried psychic connection to me that I was able to access occasionally, allowing me to syphon off your knowledge, push you in the right direction. We knew your regiment was the main opposition to our plans on the Hollow Worlds, so having you taken back there would allow us access to invaluable military knowledge. We could not have expected you to go so far, though… to get close to the inquisitor! That was beyond our expectations.’

Anto/Kulbard sat back in his seat and clapped his hands together. Outside, the sun was setting beyond the horizon.

‘That’s impossible,’ said Kretschman. ‘Suns don’t set in the Hollow Worlds.’

‘It seems your imagination has a fondness for the obvious metaphor,’ said Anto/Kulbard, as darkness crept into the carriage. ‘You’re dying, you see. Our connection is allowing me to attack Pranix from two sides at once, but you are not built for witchcraft, mortal. Your body is burning, and the only thing stopping you from experiencing that agony is my will.’

It was nearly dark, now. Kulbard was gone. The noise of the train, the motion of the carriage, had ceased. There was only Anto, the eye slits of his helmet glowing red in the darkness.

‘It’s nearly time to let you go, little puppet,’ whispered Anto, a quiet voice in the dark.

Caught between Sindri and Garreon, wielding his chainsword left and right to fend off blows from both of them, Anvindr was being backed dangerously towards one of the portals, an energy-fringed hole in reality twice as large as the Space Wolf himself. As the portal drifted his way he could see that it looked out onto some broiling clouds of red-blue energies. Was that what the Siren Clouds looked like, from the inside? Anvindr didn’t want to find out.

‘Why, Sindri?’ he demanded, ducking under his former friend’s blade.

‘Because our battles are pointless,’ said Sindri. ‘Fighting for an Imperium of dead gods and worthless mortals. We are gods ourselves, we should live as such! Garreon showed me that.’

‘What did you do to him?’ Anvindr demanded of Garreon, enraged that his brother had been broken by this monster.

‘Pain simply opens us to our true selves,’ said Garreon, leering as he dodged Anvindr’s chainsword. ‘In agony, we know what is worth fighting for, and those values which are simply… empty.’

Anvindr knew what Garreon was saying to be true. Not about the Imperium, but about Sindri. He had always had an arrogance to him that had set him apart from his fellow Space Wolves. Garreon had simply pushed him the right way.

‘The pain was worth the revelation,’ said Sindri, and his cruel smile was a mirror of Garreon’s. ‘Having had the error of my ways revealed to me, it was simply a matter of being allowed to return to your side, and waiting for the moment to prove myself to my new master.’

‘You have proven enough,’ grimaced Anvindr. ‘To me at least.’

With a howl of rage, Anvindr launched a series of thunderous blows on Sindri, leaving Garreon trapped between the rotating fragments in the chamber.

Sindri backed away under the hail of blows, back towards where Huron Blackheart was burning in the core.

Anju Badya reached the entrance to the fortress knowing that her Corsairs pursuers were not far behind her. Steeling herself, she ran through the solid blackness of the doorway, and found herself in a rounded chamber consumed by energy and battle: Anvindr and one of his fellow Space Wolves were fighting near to a column of energy within which a huge figure writhed, while the air was filled with strange objects that made no sense. But it was the blazing man near to her who held her attention.

Kretschman was alight with some kind of power that burned his skin and clothes, a current of which was pouring out of him towards the prone form of Inquisitor Pranix, who was raising his staff to try to defend himself both from that stream of energy and another coming from the staff of a Red Corsair in a red cloak. The light and fury between the three of them hurt Anju’s eyes, and none of the three paid her any attention, so focused were they on each other.

Anju didn’t understand any of it. This was beyond her, a simple rider of Tallarn.

But as she stood there, the Red Corsairs doubtless about to strike her down as they had so many others that day, she felt a strange peace.

She reached into the saddlebag she had brought with her and withdrew a large chunk of rock.

She remembered Folkvar telling her he thought that she might have survived for a reason, for a battle yet to be fought, and the look in his eyes at the moment of his death, saying that moment was still ahead.

Here it was. She knew where to strike. She knew this would be the end.

She raised the rock, a chunk of jade as big as her hand, and brought it down on the back of Kretschman’s head.

Pranix didn’t even see Sergeant Badya enter the chamber until she struck down Kretschman, but the effects were unmissable. The wave of psychic energy coming from Kretschman to Pranix ceased, rushing through the Cadian and feeding back right at Anto, a swirling mass of psychic lightning that surged into his staff, shattering it into fragments. Anto reeled, hands and cloak ablaze and ripples of malignant energy coursing over his form.

Kretschman, scorched and smoking, keeled over, while the rush of outgoing energy threw Badya out of the way.

Pranix didn’t have time to worry about either of them, or even whether Anto remained a potential threat. Only stopping Huron Blackheart mattered.

Traitor, traitor, traitor.

Anvindr’s disbelief in Sindri’s treachery had curdled into outrage and horror now, and all he wished to do before he died was strike Sindri out of existence.

Sindri had already reeled through one of the tendrils of energy working their way around the chamber, which had left his armour shattered and blackened. When part of Sindri’s chestplate fell away, Anvindr didn’t hesitate; he plunged the chainsword deep into the gap, feeling resistance as it cut through the hardened ribcage, the release as it dug deep into the organs within.

‘I hope you enjoy meeting your new gods,’ hissed Anvindr, spittle dripping down his beard with rage. Sindri’s eyes were wide, terrified in a way no true Space Wolf ever could be.

Anvindr pulled the chainsword loose and flung Sindri into the column of energy where Huron Blackheart still stood.

He turned to see Garreon coming for him, but was thrown aside by a tremendous release of energy from the column of light at the centre of the chamber.

Rotaka and Taemar found the ascent up the hill far more difficult than expected, the distance to their destination seeming to stretch away even as they should have got closer. Rotaka, uneasy enough in his alliance with Taemar, found further discomfort in these distortions.

When they reached the fortress, they were greeted by an explosion that rocked the ground beneath their feet. They ran into the chamber within to find not the aftermath of a disaster, but a scene of glory. A spherical space, at the centre of which stood a column of light, from which now emerged a spectacular figure.

Huron Blackheart was glowing with energy, starlight illuminating the air around him. As he stepped forwards the chamber around him seemed to respond, strange anomalies in the air moving towards him, crackles of energy sparking between the Tyrant and the portals and alien machinery floating past. It was as if he were part of the machinery that worked these Hollow Worlds.

No, not part – the centre of. Huron Blackheart had taken control of everything.

Rotaka had been right to stay loyal. His master was magnificent.

‘You are too late, dog,’ Huron was telling a prone Space Wolf. Others, Space Wolves and Red Corsairs alike, lay scattered around the floor, and Rotaka could see Garreon getting to his feet nearby. ‘I have control of this system.’

Huron gestured in the air, and portals began to open.

‘Where shall I start, Anvindr Godrichsson?’ asked Huron. ‘Do not be surprised – you are transparent to me now. So, where to start? Perhaps here.’

A portal opened in the centre of the room, showing the Red Corsairs fleet floating in space around the Outer Dock.

‘I could take my fleet, and let them in… here,’ said Huron, and another portal opened up, showing a world of forests and lakes. ‘Ressial, the throne world. I will bend the gravity fields around my ships, allow them safe passage to rain fire down on these mortals.’

Huron dismissed both portals with a wave. He walked around the Space Wolf, and his footsteps echoed like thunderclaps, scorch marks smoking on the stone floor behind him.

‘This is too little, isn’t it?’ said Huron. ‘Soon I shall be able to stretch the abilities of this system further, far further. How would you like to see Fenris reduced to molten lava, that Aett of yours falling into a chasm? Or the Eye of Terror and Terra itself joined together by an Archway, feeding daemons straight into the Emperor’s very throne room?’

Taemar and Rotaka were tentatively crossing the chamber, and Huron looked up. His organic eye burned pure white.

‘Taemar, Rotaka. Come stand alongside Garreon and Valthex. See your lord’s victory.’

Rotaka and Taemar stepped forwards cautiously.

‘You too, my beast,’ said Huron, and the Hamadrya ran out of the shadows, a semi-visible blur, and leapt onto its customary place, coiled around Huron’s shoulders. ‘See, I have not abandoned my gods. I do all this in their glory.’

Huron seemed confused, even in his omniscience.

‘Where is the sorcerer?’ he asked. ‘Where is Anto? Let him see me honour the powers we both worship.’

‘Sorry,’ coughed a small, mortal voice. ‘He isn’t feeling very well today.’

Anvindr had remained still as Huron Blackheart loomed over him. The terrible energies that crawled all over Huron’s body had the aura of a storm about to break, and Anvindr did not know what to say as the Tyrant ranted. Instead, he waited to strike.

The opportunity came when Pranix walked out of the shadows and blasted Huron with a bolt of psychic energy. Pranix had worked his way around the chamber, running between the stone columns, and was near Anvindr when he struck.

Anvindr rolled upwards and brought his chainsword around to attack Huron. When it hit, it wasn’t like cutting into flesh or chipping against armour, but like plunging a blade into the heart of a star. He wasn’t even cutting into part of Huron’s body, but instead was connecting with the field consuming him.

As the same energy flowed over Anvindr, so waves of it washed through the chamber.

Rotaka and Taemar tried to rush forwards as the inquisitor and the Space Wolf attacked Huron, but it was impossible to get close. The fragments and portals in the chamber had begun to whirl at tremendous speed, blurring into a storm of daggers, slashing and pushing back anyone who dared try to enter.

Rotaka, Taemar, even Garreon, all were held back.

That left Huron and his attackers at the heart of the storm.

The energy coursed through Anvindr; he could feel himself connecting to the forces at work within the chamber, and had a sense too of what was beyond that, of the forces that held the Hollow Worlds together. He felt that he could stretch his will out across it all, maybe even beyond, that he was connected to it all. He could see what Huron had sought here, why the Tyrant wanted to control it so badly: it was life, this stuff; you could build stars and worlds from it, heal your sicknesses, perhaps even raise the dead. It energised Anvindr’s body, healing the burns from his battle with Becaro, the bruises and injuries from all those other wars he had fought. That energy flowed through Anvindr’s hand and into his chainsword, which glowed like a charged weapon.

Anvindr pulled back from Huron, then brought the sword down. Huron blocked it with the Tyrant’s Claw.

‘So, you would steal my power?’ he hissed, his one organic eye staring insanely. ‘You would have it for yourself?’

‘No,’ said Anvindr.

And it was true. The power was surging through Anvindr’s mind, opening it, his awareness spreading. He could feel the turning of worlds, the complexity of the Hollow Worlds as a system, the majesty of the Siren Clouds.

He could see the universe anew.

But he wanted none of it. These visions meant nothing to him. He was a Son of Russ, a child of Fenris. He was born to hunt, raised to a life of never-ending battle. His place was not on some throne, but out in the snows. His duty and undying loyalty was to the Emperor, and such power was His and His alone.

Anvindr rejected the power, and pushed it back at Huron, bringing the chainsword around in an arc to crash into the Tyrant’s side.

As the sword made contact, the teeth clashing with the ceramite of the Tyrant’s armour, sparks flew from the contact, expanding into a burst of energy that hit Huron, defusing the energy within the Tyrant’s body. The glow of power that infused Huron, that illuminated the air around him, began to falter and flare.

‘No!’ bellowed Huron. ‘You cannot reject it. It is power – it is eternity.’

Pranix was coming in for another psychic attack close to Anvindr now, unleashing another blast of warp energy. As the bolt of power hit, Huron reeled again, and Anvindr followed it up by swinging his chainsword at Huron, a killing blow aimed at the Tyrant’s head.

‘Imbeciles,’ Huron raged, blocking Anvindr’s sword with the Tyrant’s Claw, pushing back as the teeth of the chainsword ground against the back of the power claw. ‘Can you not see what you are casting out? This is everything.’

‘It is nothing,’ said Anvindr, sweeping the chainsword away, then bringing it around to strike at Huron once again, each blow deflected by the Tyrant’s Claw but draining a little more of Huron’s power. Anvindr’s power was nearly gone from him, and as his blows drove the last of it back to Huron, so Huron’s own grip on the power was fading.

Pranix was right next to Anvindr now. His staff glowed white-hot with the psychic energy flowing through it, and tears of blood dripped down his cheeks. Anvindr stepped away as the flow of psychic energy drove the depleted Huron to his knees. The Tyrant’s skin looked drained of energy, grey and cold. He was a corpse, a dead thing, due to enter his long-delayed grave.

‘You must strike the final blow,’ snapped Pranix. ‘I can’t do it.’

There was enough of the power left in Anvindr for him to see through the petty workings of Pranix’s mind.

‘That isn’t true,’ said Anvindr. ‘Even now you seek to manipulate me, inquisitor. You could strike that blow yourself, but you know that it will likely kill you to do so. So you demand the sacrifice from this old Space Wolf instead.’

Pranix was speechless.

Anvindr laughed. Huron was on his knees now, his gaze slack and listless as the power was stripped away from him.

‘It doesn’t matter,’ said Anvindr. ‘It is who you are. That is your wyrd, to manipulate and scheme, Pranix. It is my wyrd to fight, and this is my final battle. My thread is coming to an end.’

He took the staff from Pranix’s hand. He could feel the psychic charge in it. A blow from such a weapon would shatter anything.

‘I have seen my final winter,’ said Anvindr Godrichsson.

He brought the staff down, heading towards Huron’s lolling head, a killing blow to finish the Tyrant.

And it was deflected. Sindri, blood bubbling from his mouth, knocked Anvindr aside, and the psychic blast went wide, hitting the fading core behind Huron. The staff in Anvindr’s hand broke in half, the psychic blast pushing him backwards.

Sindri laughed a final laugh, and fell sideways, eyes glassy.

The storm in the chamber ended as suddenly as it began, the core at the centre of the chamber closing, rock reforming around it to create a central pillar. The speed of the portals and devices floating in the air began to slow.

Anvindr looked around. Four Red Corsairs were closing in on him at speed, now the barrier separating them had gone.

‘Godrichsson, your sword,’ called out Pranix. ‘Kill the Tyrant, now.’

Anvindr didn’t hesitate; he swung his chainsword around, the blade revving, swinging it right at Huron Blackheart’s neck.

And Huron looked up, a residual spark of his lost power in his eye, flaring. A cruel smile twisted the corner of his mouth.

Anvindr could feel his sword slowing in the air, a strange energy holding him back. Around him, there was a similar lack of motion, the running Red Corsairs frozen in space, Pranix’s mouth half open in a shout of warning.

‘You have not relieved me of all the power this place holds, Fenrisian,’ said Huron Blackheart, standing up and stepping aside from Anvindr’s slow-moving blade. ‘We are evenly matched, but my understanding is greater. Enough to manipulate the forces within these worlds, to deny you your prize. You will not take my head, or that of any more of my Red Corsairs.’

He reached up with the Tyrant’s Claw, and a portal drifted down from the ceiling. Through it, Anvindr could see an image of Huron’s fleet, then within the ships themselves, the portal breaking into many smaller portals, showing the dank interiors of different ships.

‘I send my Corsairs home,’ said Huron, and ribbons of energy reached out from the portals, wrapping themselves around the Corsairs in the chamber, even Sindri’s fallen body. They disappeared, portals forming around them then closing. Still connected to the same power as Huron, Anvindr could feel that this was happening everywhere, that across the Hollow Worlds portals were transporting the Red Corsairs back to their fleet. In spite of that connection, Anvindr could not break free, or stop Huron. The Tyrant’s will, the enormity of his determination and ego, was too great.

Then there was only one portal, floating behind Huron, leading to a darkened room aboard a ship, starlight from a great porthole illuminating a throne, a wall of trophies, a wooden chest.

‘You live today, Space Wolf,’ said Huron Blackheart, stepping through the portal. ‘But know that I do not forgive your defiance this day, and if I cannot avenge myself on you, I will strike against your Chapter instead.’

Then he was gone, the portal closing behind him. Anvindr found himself moving again, and his chainsword swept through empty space.

Pranix scrabbled towards the patch of floor where Huron had been, whispering ‘no’ to himself under his breath.

Anvindr watched him for a while.

A few minutes later, Tormodr ran into the chamber. He seemed to have lost most of his power armour, and his tattooed torso was covered in cuts.

He paused in the doorway, staring at everything. Then he saw Anvindr.

‘The Red Corsairs have gone. Vanished,’ said Tormodr. ‘Just as I had them where I wanted them, too.’

Anvindr laughed, then he remembered Gulbrandr, and Sindri, and his laugh faded.

He could still feel a hint of the power within him. If Huron could open a portal, perhaps Anvindr could bring back…

No. Like Liulfr, they had earned their rest.

Anvindr, it seemed, would see another winter after all. That was just his wyrd. ‘Who survives?’ he asked.

‘A dozen or so of our brothers, though many are badly wounded,’ said Tormodr. ‘A handful of mortals. The system governor survives. Young Hoenir fell.’ Tormodr looked around the chamber, his eyes resting briefly on Gulbrandr’s body, then moving away. ‘Where is Sindri?’

‘That is an account for later,’ said Anvindr.

‘Indeed. Can you open a portal back to Threshold?’ asked Pranix. The inquisitor had regained his composure, although there was a new twitch beneath one of his eyes. He was limping, trying to hold himself up on one half of his staff.

‘No, my lord inquisitor,’ said Anvindr. ‘But I believe there is already…’

He reached up, and one of the portals floating by drifted downwards, stopping at floor level. Anvindr gestured again, and it opened up to the size of a Space Marine.

‘Let’s gather the others and go,’ said Pranix. ‘We don’t know how long this will remain open.’

‘Don’t you want to stay here, inquisitor?’ asked Anvindr. ‘Plunder this place’s secrets for the benefit of the Inquisition?’

Pranix blinked.

‘Captain Godrichsson, the powers in this place are unholy and heretical,’ snapped Pranix. ‘I should have you and any other surviving Space Wolves purged for even coming into contact with it. You especially, having some residual contact with such witchcraft.’

Anvindr looked down at the inquisitor, this mortal who he had hated so long, still twisted up in his schemes and hatreds.

Then he laughed, and this time nothing could stop him.

Twenty-Nine

If Huron Blackheart’s flight from Exultance could be considered a defeat for the Red Corsairs, it seemed far from a victory to the loyalists of the Imperium.

A whole world, Hacasta, was gone, and with it the Burning Monks and many other prominent representatives of the Ecclesiarchy, tearing the spiritual heart from the system.

Another world, Kerresh, was blighted by a dying sun and barely habitable, the centre of industrial activity within the Hollow Worlds left utterly devastated.

Millions had died, not just on Hacasta and Kerresh, but across all the worlds where the Red Corsairs had invaded. Of those who survived, many once-loyal subjects of the Emperor had either accepted the taint of Chaos into their souls or been corrupted by the very presence of such heresy. Further millions would need to be purged to clear those worlds of all dark influence.

Inquisitor Pranix tasked surviving forces of the Lastrati Guard and Jandarme with undertaking the purge that was required, under the highest Inquisitorial authority. He then ordered specific elements within those forces to watch their comrades for signs of heresy themselves, and to show no mercy if they became tainted with the very heresy they had been ordered to stamp out.

As for the Red Corsairs themselves, defeat of such an enemy’s objectives was not enough, either for the inquisitor or the Space Wolves. Even with the Red Corsairs having fled the system, their legacy remained. Not just in the taint of heresy they had inflicted upon the Lastrati, the souls lost to them, but written into the geography of the Hollow Worlds, the system itself left changed forever.

The Archways created by Huron’s realignment of the Orrery remained. Although Exultance was once more inaccessible, the once-lost world of Threshold was now part of the system again, and was the only link between Ressial, Trincul and the worlds on the Hellward side of the system.

Those few survivors on Kerresh who had not already fled to Plini relocated to Threshold, and Lord Dumas Cheng was considering forced population transfers from Laghast to turn Threshold into the Hollow Worlds’ new industrial hub. As Kerresh became a cold, barren wasteland, only crossed when necessary and with elaborate precautions against the environment, Threshold was returning to life.

From a balcony on one wing of the Gatehouse, Lord Dumas Cheng looked out across the ruins of the Onyx Palace, home for an Emperor who would never visit, now reduced to rubble. Some of its outer walls remained intact, jagged and uneven, while where rooftops had been torn away once-opulent interiors were now exposed to the elements, stained and rotting.

Cheng sat alone, parchment in his hands. When he had become system governor of the Hollow Worlds, it was a given that the system stood alone, that it was secure from many of the terrors that plagued the universe. For many millennia the Hollow Worlds had been a virtually closed system, providing all that was asked of them in tithes and troops to the Imperium at large, but requiring little in return. The Lastrati had been proud, independent but dependable.

Now that independence was gone. Resources were needed, and a vast influx of newcomers to repopulate the system. It would take much to rebuild the Hollow Worlds, and the Lastrati could not do it alone.

So, overlooking the ruins of the Onyx Palace, Cheng took pen and parchment and began to draft a request, to be sealed and transmitted to the highest authorities in the bureaucracy in this part of the Imperium, to superiors no system governor of the Hollow Worlds had seen fit to contact in endless generations, requesting assistance.

As he wrote, he was aware that he was very possibly writing his own death warrant. The High Lords of Terra and their local representatives did not tolerate failure, whatever the circumstances, and until reconstruction and repopulation were at least partially complete the Hollow Worlds would not meet any of its tithes. Cheng would be responsible for this failure, and his request for aid was an admission of such.

He would doubtless be purged, the authorities imposing another system governor, who would in turn bring with him an army of lackeys and bureaucrats to stamp their own mark on the Hollow Worlds, sweeping away the previous regime and deleting them from the histories, denouncing Cheng’s failures.

When he had finished writing, Cheng melted a patch of wax onto the parchment, and raised his stamp of office. He paused for a second. Was it worth it, to ask for aid? To risk bringing brutal outsiders into the Hollow Worlds, to admit defeat and potentially end his life executed as a traitor? Would it not be better for the Hollow Worlds to go on alone, under the old regime, even if it meant slow decline?

No, thought Cheng, that too was impossible, and more shameful than any repudiation. They were subjects of the Emperor, and whatever needed to be done to restore the Hollow Worlds so they could serve the Emperor once more, that was worth the cost.

Who knew, he thought; the wheels of communication and bureaucracy ran painfully slow and he was already an old man. By the time his message was received, processed, a reply formulated and the response sent, Cheng might be dead. They could put his corpse on trial as they began reconstruction.

Cheng smiled at the thought. Then he brought down the stamp with a thud.

The patient was unnamed, and carefully kept away from anyone who might be able to identify him. Wrapped in bandages and unable to speak or move, violet eyes were his only distinguishing features. In the weeks following the departure of the Red Corsairs from the Hollow Worlds, the patient was moved from infirmary to infirmary and world to world, eventually settling in a familiar hospital on an island on the outer world of Laghast. Beneath his bandages, the patient waited.

It was there, in the quiet hospital out in the archipelago, that the patient had a visitor. The visitor walked with a limp, and stood in the doorway of the patient’s room leaning on a walking stick made from the broken half of an ornate staff. He had abandoned his robes and armour in favour of what looked like, from a distance, one of the drab uniforms of a Ministorum clerk, but which closer inspection would reveal was made from the finest fabrics, immaculately tailored.

The visitor closed the door behind him, and pulled up a chair to sit by the patient’s bed. The patient watched him warily.

‘Hello, Kretschman,’ said Inquisitor Pranix, leaning his stick against the side of Kretschman’s metal bed. ‘Although I probably shouldn’t use that name. Due to your disgrace your name has been stricken from the records of your regiment. Officially you’re not just dead, you never actually existed. Makes me wonder why I bothered faking your death.’

Kretschman tried to convey maximum contempt with his gaze alone. What little Kretschman had left of himself after Anto invaded his mind – his name, his honour – had been stripped away by Pranix.

The corner of Pranix’s mouth twisted in a slight grin.

‘Don’t be like that, Vetera… Well, not veteran sergeant any more now you’ve been posthumously stripped of your rank, I suppose, so I guess that makes you just plain Kretschman,’ he said. ‘What was I saying? Yes, don’t be like that, Kretschman. It could be worse, especially if anyone other than I ever found out you were alive. Sergeant Badya told quite a few of the Space Wolves about the strange Cadian helping the sorcerer to kill the inquisitor with his psychic powers. Fortunately it was easy enough to spirit off your “remains” as contaminated material touched by the Ruinous Powers. The Space Wolves were furious, as they wanted to impale your corpse on a spike, but then the Space Wolves are always furious about something, aren’t they?’

Kretschman felt resignation sink over him. There was nothing he could do to avoid his fate now.

Pranix leaned in, his voice low and conspiratorial.

‘But you and I know that you were never consciously a traitor, don’t we, Kretschman?’ the inquisitor whispered. ‘That was your brilliance as a spy in our midst – you never knew you were one, and that connection the sorcerer planted in your mind was buried so deep, even I couldn’t detect it. The irony is, as far as you were concerned your loyalty never wavered, did it?’

Kretschman wanted to nod his head, but couldn’t, instead staring in desperate affirmation at Pranix, to try to convey that this was true, yes, he had always been loyal.

Pranix sat back in his chair, which creaked under his weight.

‘Don’t think for a second I’ve saved you because you’re some innocent soul,’ snapped Pranix. ‘That means nothing to me – I’ve seen many a perfect innocent to their death, and never regretted it. No, you’re alive because you may still have your uses. That connection you had, I want to find out how it was done, and how it evaded my detection for so long. I also want to see if I can use it, and you, against these traitors and others like them. Would you like that, Kretschman?’

Kretschman’s eyes implored Pranix that yes, he would.

‘I thought so,’ said Pranix rising to his feet. ‘Not that you have a choice. And don’t consider this a total reprieve. If you prove to still be dangerous I’ll have you put down. And if it’s easier to dissect you to discover what was done to you, I’ll do that. But you never know, you might actually live to redeem yourself.’

Pranix walked to the door, leaning on his stick once more.

‘You will be transported off-world within a few weeks to complete your recovery, so in the meantime concentrate on getting better and, should you regain your speech, keep your mouth shut,’ said Pranix, opening the door and glancing back.

‘Whatever comes next, you’re going to need your strength.’

Then he was gone, leaving Kretschman to listen to the sound of his walking stick clacking down the corridor.

‘What do you see, Rotaka?’

The question came as a surprise, although Rotaka had not known what to expect when summoned to the Tyrant’s quarters on the Might of Huron. They had been in the void for what seemed like many weeks, although knowing the vagaries of the void, it could have just been days. Time had limited meaning there.

‘My lord?’ asked Rotaka.

‘It was a simple question, Rotaka,’ repeated Huron Blackheart, emerging from the shadows. ‘What do you see?’

‘I see you, my lord,’ said Rotaka. ‘My master.’

Blackheart looked down at Rotaka, his insane eyes glowering. Rotaka hadn’t been this close to the Tyrant since Exultance, and there was a sharpness to that gaze that had seemed lost for so much of the campaign in the Hollow Worlds. While not possessing the terrible power he had taken control of on Exultance, the Tyrant no longer obviously bore the signs of daemonic infection. There was a new energy to Huron, a strength of purpose. A cruel smile pulled at the corner of his lipless mouth, back teeth visible through one of the wounds in the grey skin of his cheek.

‘But you see more than others, don’t you, Rotaka?’ said Huron. ‘Only lately did I discover that you drank from the Cup of Blessings on the eve of our last campaign. Was that when it started, Rotaka? I saw you make your choice on Threshold, I saw that your eyes looked at me on levels those around you could not.’

Huron was circling him now, almost whispering in his hoarse, grating voice. Rotaka didn’t answer any of Huron’s questions; he could tell the Tyrant hadn’t finished yet.

‘You saw, didn’t you?’ hissed Huron, resting one blade of the Tyrant’s Claw on Rotaka’s shoulder as he paused there, almost speaking into Rotaka’s ear. ‘That I was inflicted, that a daemonic presence was threatening to overcome me, to use me as a mere conduit to force its way through from the warp.’

‘Yes, my lord,’ said Rotaka. There seemed no point in lying.

Huron walked around to face Rotaka once more.

‘So, I ask you again,’ Huron said. ‘What do you see? And this time, answer me fully.’

Rotaka looked at Huron. He had no idea why the previous visions had struck him when they did, but even between those sights, he had found himself seized by an unrest when looking at Huron Blackheart, the same sensation he had always felt when looking at that semi-visible familiar the Tyrant kept with him.

So now he looked, and opened his senses, seeing if any such instinct began to affect him.

He saw nothing. For many, the sight of Huron Blackheart would be disturbing enough – the dead flesh, the augmentations, those eyes. But now, Rotaka saw him as he always had, as his master, as Lufgt Huron. All previous doubts and uncertainties had gone from his mind.

‘I see nothing aside from my master,’ said Rotaka. ‘No affliction or distortion of the senses, just my lord and master.’

‘You have always served me with devotion, Rotaka,’ said Huron. ‘So I will speak to you truthfully. You are correct. Although I did not gain the power I sought on Exultance, the daemonic infection that gripped me has been forced into abeyance, at least for the moment. If I ascend to daemonhood, it will be on my own terms.’

‘I am glad, my lord,’ said Rotaka with a slight bow of the head. And he was.

‘Would you be so glad if you knew the price of this physical presence, Rotaka?’ spat Huron. ‘What is the price of being fully engaged with reality, if not pain?’

He raised the Tyrant’s Claw, scything the air with its blades.

‘My existence is wracked with pain beyond imagining, Rotaka,’ said the Tyrant. ‘Unending pain.’

‘For that, I am truly sorry, my lord,’ said Rotaka, and that statement was also true, even if he was uncertain why Huron Blackheart would seek to share so much information.

‘You speak the truth!’ said Huron, appraising Rotaka as seriously as he had demanded Rotaka appraise him. ‘Loyal, loyal Rotaka, your soul truly bleeds for me, doesn’t it?’

Rotaka returned his gaze.

‘You are my leader, my lord,’ said Rotaka. ‘I have always followed loyally and always will. Your pain is my pain.’

‘Such loyalty,’ said Huron. ‘Such sympathy.’

Rotaka felt a swell of pride at Huron’s approval.

Then he felt the something go through his neck.

Huron Blackheart had struck him with one blade of the Tyrant’s Claw, piercing Rotaka’s throat.

‘Even without the powers granted to you by that cup, you see me as no others do,’ hissed Huron, eyes wide with madness. ‘And it will not stand. You see a Chapter Master long dead, not Huron Blackheart. I will not be constrained by your worship or your empathy, Rotaka. I am Huron Blackheart, and I will rule through fear alone. No one is allowed to know me as you presume to do.’

Huron jerked the blade sideways, taking out half of Rotaka’s neck.

Rotaka fell to the floor, dead.

Huron Blackheart left the corpse where it lay, and walked over to his throne. He sank into it, his body wracked with agony. While the daemonic presence had been driven away, at least for now, Huron’s existence was still a tenuous one dependent on technology, sorcery and his own strength of will. To keep living was more effort than his Red Corsairs could ever be allowed to know.

Huron dismissed such thoughts. Pain was nothing; he had new purpose now, and he would live until all his conquests were complete. Straightening in his throne, he pressed a vox-button on one arm.

‘My lord?’ came Garreon’s voice.

‘I have a fresh corpse for you, Corpsemaster,’ said Huron. ‘Send your servitors to gather it from my quarters. Strip out the organs to heal our wounded.’

‘Yes, my lord,’ replied Garreon, audibly confused as to where such a corpse might have come from. ‘As you command.’

‘Garreon,’ added Huron, before the conversation terminated. ‘Do you know of an artefact held by the sorcerer Anto, the Cup of Blessings?’

‘I am aware of it, my lord.’

Huron paused, then decided. ‘Find it, have it destroyed,’ he said.

‘As you wish, my lord.’

Huron lifted his finger from the vox-button, terminating the conversation.

As Rotaka’s blood pooled on the floor behind him, Huron Blackheart sat, staring at things only he could see, the dead captain already forgotten.

The battle against those mortals tainted by contact with Chaos took Anju Badya across the Hollow Worlds and eventually to the city of Eridano on the outer world of Laghast.

A strike force of Tallarns and Lastrati had been engaged in a street-by-street struggle with a Huron-worshipping cult, the members of which welded metal plates over one side of their face as an act of devotion. What these fanatics lacked in peripheral vision they made up for in ferocity and numbers, and the fighting had raged across the city, criss-crossing bridges over the grey, polluted waters of Laghast.

Then the Space Wolves came, fighting their way into the heart of enemy territory, a path which the Tallarns and Lastrati followed, mopping up stray survivors fleeing the onslaught. Badya felt no pity as she felled the masked heretics, as they babbled about the brutality with which they had seen their fellows gunned down. They had allied themselves with the Emperor’s enemies, those who had brought the Hollow Worlds to their knees, and now they went to their deaths knowing the depth of their error.

It was in the aftermath that Anju found herself looking for survivors to finish off in the ruins of a desecrated cathedra, and crossed paths with Anvindr and Tormodr. She did not expect them to remember her, a mortal rider at the periphery of their battles.

‘Sergeant Badya,’ growled Anvindr Godrichsson. ‘Your wyrd brings us together once more.’

‘Captain, now,’ said Anju automatically, then regretted it. What did demigods care for her rank? ‘My lord,’ she added quickly.

‘Captain Badya,’ said Anvindr, with undue emphasis on the title. ‘I recognise my failing and will be sure to correct it.’

Tormodr made a deep, amused grunt.

‘A captain, not a sergeant,’ said Anvindr. ‘And a rider without a mount. Much has changed for you, Anju Badya.’

‘As for us all, my lord,’ replied Anju. It was an impertinent response, possibly unwise, but Anvindr seemed… unburdened compared to how he had been before.

‘We have all had to change – we have lost pack members and brothers and comrades,’ said Anvindr. ‘But our wyrd takes us to strange places, captain. Some threads are longer than others, and it does us no good to fret about it. Those we have lost will go remembered in our sagas.’ He looked sharply at Anju. ‘As are you, Anju Badya.’

‘Me?’ asked Anju.

‘Yes, you. Not by name, not always, but in the accounts of this campaign the skjalds mention the mortal who accompanied Folkvar across the wilds of Hacasta, and who witnessed his last moments. Who brought the intelligence on Kerresh that allowed for the liberation of Tormodr and–’

Anvindr stopped himself from saying something, and a flash of the old regret passed over his heavy features. Tormodr gave Anju a nod of respect while Anvindr found his words.

‘Then on Exultance you struck down the sorcerer’s puppet in the final battle,’ said Anvindr. ‘These acts will be remembered in the accounts.’

‘Remembered?’ said Anju.

‘Remembered and retold, until the last Space Wolf draws his last breath and is unable to retell them any more,’ said Anvindr.

Anju was lost for words, trying to take in the scale of what Anvindr had told her, and what the correct response might be.

Then the sound of gunfire erupted nearby, and the Space Wolves were running once more, shouting their war-cries and raising their weapons, lost once more in the never-ending warfare that was their wyrd.

It was some days later that Huron Blackheart, as he had done on the eve of his invasion of the Hollow Worlds, drew together his officers on the Might of Huron, gathering them in the great hall once more. Then, they had known what the agenda was, as the battles ahead had been planned for many months.

This time, the purpose of the gathering was uncertain, and if the officers were not nervous – the Red Corsairs, even in the presence of their master, were hardly easy to intimidate – there was a muted uncertainty that lingered over the occasion. Why gather them now? The warband had suffered terrible losses, and they had yet to reach their home base in the Maelstrom to begin the recovery. Instead they were moving away from the Maelstrom, direction unknown.

The schism that had briefly risen within the ranks had been resolved definitively in Huron’s favour, with any potential doubters that had survived the Hollow Worlds disappearing in the long space flight that followed, but still the memory of betrayal, and of purging, left unease in their wake.

Valthex did not share these sentiments; he was simply irritated to be pulled away from his researches. The Tyrant had not summoned Valthex since they departed the Hollow Worlds, and the Techmarine had been lost in the data he had gathered in the Orrery, on Exultance, across all those worlds with their mysterious technologies. He was sure that the secrets of the Archways and the other technologies that kept those worlds moving would be his, given time, but progress was painfully slow.

His thoughts were interrupted by Huron Blackheart striding into the hall. He moved with a sense of purpose, drawing every eye to him, surveying the room of Red Corsairs with confident mastery. When he spoke, it was with total command.

‘I have gathered you here, my Red Corsairs, in the wake of our campaign in the Hollow Worlds, to tell you that although our enemies may think us defeated, we are not,’ boomed Huron. ‘Though we were driven from the Hollow Worlds, we have left them in ruins, and the residue of the power I touched at the heart of Exultance lingers within me still, and has ensured I shall lead you all for centuries to come. I assure you, Huron Blackheart will never die, and in exchange for your undying loyalty I will lead you to ever greater glories, and we will bring the Imperium and its dogs to their knees.

‘Yes, we have incurred losses, and betrayals from within our own ranks have cut deeper still. Yet we are stronger without those who harbour doubt, with the treacherous and the disloyal cut down and scourged from our ranks. Those who turned against me were not fit to be Red Corsairs, while those who still stand are the strongest. Fools may consider us moribund, but you, my Red Corsairs, my loyal servants, are the spine of a warband which will grow stronger than ever.

‘For though you serve me without question, as Red Corsairs we are all of us free, not just from the Imperium but from its endless history. And there will be others inspired to join us. Let it be known that any who join our ranks can cast off their own histories and forge themselves new glories, as a Red Corsair.’

Huron gestured to Taemar.

‘Look to Taemar, for example, he who once served different masters but now is as true a Red Corsair as any other. For his service in this last campaign, I name him my Champion.’

Taemar bowed deeply at this honour, seeming to drink in and savour the murmurs of discontent at his elevation.

‘Let Taemar be the exemplar,’ shouted Huron. ‘Let us draw into our ranks all those from other Chapters, other warbands who wish to take my mark, who believe that they have the greatness to stand amongst us.’

There was a roar of approval from the gathered Red Corsairs at Huron’s testament to their greatness.

‘Our ranks already begin to grow, bringing not just warriors, but intelligence,’ said Huron. ‘Step forwards, newcomer.’

Valthex watched with his enhanced senses as from between the lines came a Space Marine, one still moving slowly after recovering from recent injuries. A diagnostic scan revealed that organs stripped from the body of Rotaka had been implanted into this newcomer, allowing his survival. His power armour too was mismatched and augmented with pieces from fallen Corsairs, but on the original pieces, beneath the scars and the red saltire, the markings of a Space Wolf could still be seen, prompting unease in the Corsairs around him.

‘What are you, Sindri?’ demanded Huron Blackheart. ‘A Space Wolf? A hound of the Emperor?’

‘I deny the Emperor and all the Imperium,’ spat Sindri in reply, his voice echoing across the chamber. In spite of his injuries he was defiant, energised with rage and hatred. ‘I renounce the Space Wolves and reject their inheritance. I am a Red Corsair, and I serve only Huron Blackheart.’

To a roar of approval, Sindri dropped to one knee and bowed before Huron.

The Tyrant tapped him on one pauldron with the tip of one of the Tyrant’s Claw’s blades.

‘Rise, Sindri,’ said Huron Blackheart. ‘Join your brothers, but first, tell them what you told me. Tell them of the ship that will be our next prize, through which we will seek revenge on these Space Wolves.’

‘It is a strike cruiser, a prize not just for the Space Wolves as a Chapter, but for one of the very companies that fought us on the Hollow Worlds,’ said Sindri, fulfilling Huron’s promise by rewriting even his own history as he spoke. ‘Its loss would bring great shame and dishonour on those Space Wolves.’ A cruel smile pulled at his mouth. ‘And I can lead you right to it.’

‘Are you ready?’ asked Huron Blackheart. ‘Are you ready to follow me to take this ship? To strike back at these damnable Space Wolves and the Emperor they serve?’

There was a tremendous tumult, and amongst the gathered Red Corsairs, Sindri roared as loudly as any of them.

‘Then we will seize this vessel and kill every Space Wolf on board,’ roared Huron, even his voice barely audible over the cheers.

‘Set a course for Parenxes,’ shouted Huron. ‘There we will find our prey, the Wolf of Fenris.’
