About the Author

An Extract from ‘Imperator: Wrath of the Omnissiah’

A Black Library Publication

eBook license

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.

>>> EXLOAD COMMENCING >>>

>>> INFORMATIONAL >> THE KRISTOS HETERODOXY

Even before the first rogue traders started chasing the ‘Legend of Sthenelus’, before the apostles of Mars launched their first missions to that lauded, benighted world, belief in a universal organiser pervaded its mechnomadic culture.

The similarities with the doctrines of Mars, the Omnissiah as architect and caretaker, must have been striking.

Many on the Martian Synod saw this convergent cultural evolution as evidence that the quasi divinities known by the Medusans as the Clan Patriarchs [SEE INFORMATIONAL SUB-PACKET >> MYTHS AND LEGENDS] had been pioneers of Martian, as opposed to Terran, extraction. Against the backdrop of cultural and territorial struggles that shaped the allegiances of Old Sol, even through the height of the Great Crusade, it was a convenient claim. It justified the efforts to draw this new world from Terra’s embrace and into the orbit of the Red Planet. Magos anthropologicae studying the Medusan cultures have posited that the universal organiser, the Omnissiah as the phenomenon is now recognised, arose simply out of a gradual mythologisation of the Clan Patriarchs and the precursor myths associated with them.

This theorem has been discredited numerous times over the millennia [INDEX >> CANTICLE OF TRAVELS].

The great schema, built into the galactic order by the Omnissiah from its outset, manifests in all things. To say that all proceeds in accordance to His will would be inaccurate.

It proceeds in accordance to His design…

PROLOGUE

The command nexus of the Ryen Ishanshar – or Red Moon over Isha’s Spear in baser tongues – was restraint under the guise of opulence. Every curtain-draped gallery and arcing staircase was integral to the form, every piece of entablature, wainscoting and golden-leafed frieze a statement of a subtle puritanism. Statuary depicting fallen gods and the heroes of the Eldanar emerged from the walls in the most lifelike of ways, as if the divinities themselves had been coaxed from the wraithbone under the urging of the artisan. Living eldar stood or sat within jewelled banks of psychoplastic displays, guiding their mother ship by thought, by song and, where necessary, with the dextrous play of their hands. Precious stones embedded in seemingly uncrewed stations pulsed and throbbed, the jewel displays around them strobing under the deft commands of the dead.

Banners portraying the Doom of Eldanesh fluttered as a moaning whale song reverberated through the nexus. The Ryen Ishanshar was a mind formed from its crew’s minds. Coupled to both in identity and spirit, Navarch Elrusiad felt their distress as his own.

He stood in the nexus’ centre, gloved hands wrapped around a pair of half-circular rails that hardened or softened depending on the tension of his grip. He wore a full suit of sleek blue body plastek ribbed with yellow struts. A brace of shuriken pistols and a curved powerblade were belted at his narrow waist. A cloak of prismatic crystal scales hung over one shoulder, mirroring the nexus’ coloured lights. Over his face was a mask.

The expression it wore was the blankness of deep space, the psychoplastic marked only by a single bright star etched upon the cheek. The Star of Hoec. The Mariner’s Star. It concealed his thoughts as it concealed his face and, through him, guarded the Ryen Ishanshar and her crew from each other.

He felt them respond to his calm.

‘The human vessel is coming about,’ announced Laurelei, circling the Navarch’s dais with one hand upon the jewelled hilt of her sword, one foot forever on the Path of the Warrior. ‘They are preparing to fire.’

+Brace for impact,+ he thought.

The ship shuddered. Harmonies rang through the nexus as its kinetic supports sang off the impact energy, massed firepower from a behemoth eight times the Ishanshar’s displacement making a mockery of her holofields. Blows landed purely by chance. The ship cried out. At the wayfinder array, Marendriel shivered in transferred pain.

Elrusiad held his thoughts in equilibrium. He knew what his ship could shoulder.

+Show them our tail, Marendriel. Full sail for the webway. Let the great bull pursue nimble Kurnous. Let it destroy its own forest in its rampage. They will not forget the fate of the one they call Khan. They will not dare pursue us there.+

Laurelei turned towards him. Her high-boned features and reputation for quick anger made her appear ever haughty. ‘And what of Autarch Yeldrian? If he should return to find us not here?’

+We cannot fight this leviathan, beloved.+

Laurelei snorted and turned her back.

Equanimous, Elrusiad looked past her to the wayfinder. +Let us see if the mon-keigh can run.+

Marendriel was already fulfilling the task, and Elrusiad sensed the subtle shift in balance as the Ryen Ishanshar’s fully extended sails caught the solar winds. His grip on the rails tightened, the viscoelastic metal hardening to welcome it, as acceleration pushed him onto his heels.

With a billion subtly coupled senses, he watched the Imperial beast fall off the chase, seeing the great horns of the raging god-bull in its indiscriminate raking of the void.

+Tack an iota to port. Adjust holofields to convergence.+

He almost pitied humanity.

Their spell amongst the stars would be brief.

It was no longer fear or anxiety that coursed through the Ryen Ishanshar’s infinity circuit, but rage. Her ancient bones trembled. Her psychoactive skin bristled with graviton pulsars and fusion beamers, the lingering hatreds of the ancestral dead putting fire to the hearts of the living. He could sense her fury that ones such as her could be ambushed by ones such as…

These.

+Peace, Ishanshar,+ Elrusiad sent, struggling to contain her. +Only… Asuryan’s eye… sees all.+

Marendriel had her hands splayed a breath above the wayfinder console. Her face was turned side-down as though listening to the instrument’s reports with more than just her mind. ‘Two strike cruisers, seven escorts, in addition to the behemoth.’ The spirit stone embedded in the console beside her pulsed brightly, emitting a vibrato squeal of song. ‘My apologies. Eight escorts.’

Through the Ryen Ishanshar’s eyes Elrusiad saw the enemy’s disposition.

+They mean to seize us. They knew we were coming.+

‘You speak of mon-keigh,’ said Laurelei. ‘Not the crones of Morai-Heg.’

Elrusiad shut his eyes. The shudders running through the deck eased, the ship calming as it sensed his intent. He felt its urging spirit. +Yes+. Common will filled him, and his arms lifted of twinned accord.

The crew averted their eyes, touched their waystones and whispered songs to dead gods, even warlike Laurelei, as the Ryen Ishanshar groaned under the ranging shots of the coming wave of human warships.

Without a word, he took the sides of his mask. It came away with ease, released from his face the moment he had decided to remove it.

He turned it over in his hands.

For a moment, an implacable rendering of his own face stared back at him, but the weak psychoplastic was already beginning to lose its connection to his psyche, turning soft and losing the mould of his face with it. He sighed, fiercely sorrowful. His heart pounded like a leaden drum.

And he lifted the mask back to his face.

Liquid plastek crawled over his flesh as the mask’s opposite face reshaped to his features.

The mouth curled into a sneer and the eyes narrowed. Its expression hardened. The Star of Hoec faded, and in its place a shallow groove extended from the corner of the eye and cut down into the plastek. A solitary tear, shed in recompense for the taking of a life.

On any mariner’s Path, there came a point when he must surrender to the aspect of Kaela Mensha Khaine.

The prospect filled Elrusiad with no dread now.

His soul was molten metal as he looked up with newly blooded eyes. A red haze pooled around the edges of his vision, and where previously he had seen the steady throb of jewel lights and spirit stones, he now felt the rising pulse of war. He could see Marendriel struggling visibly to keep her splayed fingers from curling into claws. Laurelei licked her drawn blade, raising a hiss of steam as though the blade were fresh from Vaul’s anvil.

Elrusiad felt no need to draw his own weapons. His mind was twinned to their greatest weapon. The Ryen Ishanshar purred with the unanimity of violence.

As though he were a farseer assigning the Mark of Doom, Elrusiad raised a finger and singled out the lighter of the two cruisers, which was closing in fast.

His voice was smoke.

‘This one will be first.’

>>> HISTORICAL >> THE BATTLE FOR FABRIS CALLIVANT, 212414.M41

Each of the Imperium’s million worlds exists in a permanent state of war. Sprawling networks of industry and bureaucracy transform the diaspora of far-flung worlds into men and arms on uncounted battlefields. Crops and livestock move across sectors and segmenta. Mineral wealth is stripped, ground down to the raw material for war machines and starships, fed in an endless cataract of bounty into the forge-temples [ACCESS SUB-PACKET >> TREATY OF OLYMPUS] of Holy Mars. Children are tithed to its armies, the innumerable billions raised into the endless grinder of the Imperial Guard. From the noblest civilised world, to the meanest prospect-colony in the Astronomican’s shade, to Mars itself, the economy and culture of every world is shaped by that network of interdependence, and by ten millennia of perpetual and rising threat.

For a world on the front line of the war without end, the scale of the Imperial war machine is staggering to behold.

Fabris Callivant is a Knight world, proud, ancient and home to a ruling house that has governed through an unbroken line of primogeniture since before the Age of Unification.

The planet is the home port for a flotilla of a dozen semi-retired vessels under the flag of the Mars-class battle cruiser Golden Ratio, their strength supplemented by that of a combined fleet of over fifty vessels tithed from allied and patron forge worlds throughout the sector. Dozens of warships drawn from Battlefleets Trojan and Dimmamar hang becalmed in neighbouring anchorages, alongside the imperious and more glorified vessels despatched from Warfleet Obscurus at Cypra Mundi. The crux of the world’s orbital fortifications however is the ancient star fort, Darkward, a rugged bauble of crenels and turrets painted in the red and black of House Callivant. The troop capacity and firepower of the combined fleets is formidable, but to Princeps Fabris, and the Imperial and Martian commanders to whom he is subordinate, the heart of the system’s defence lies elsewhere.

Nine illustrious warships of the Hospitallers Chapter held anchorages in high orbit, led by the thousand year-old battle-barge, Shield of the God-Emperor.

The Hospitallers are itinerant crusaders [ACCESS SUB-PACKET >> CHAPTERS OF THE TWENTY-FOURTH FOUNDING], their fleets patrolling pilgrimage routes that criss-cross the subsector.

Pilgrimage and trade have both grown in the millennium since the Chapter’s Founding, bringing prosperity and peace to worlds that would not have known either, had Imperial Saints not broken the enemies of Man upon their fortification over the ten millennia past.

Fabris Callivant was not one of those worlds, but it lay near enough for its plight to have imperilled those holier and wealthier, and for the Hospitallers to extend their arm to its protection.

For a brief time in the middle third of M41, Fabris Callivant became the epicentre of the war without end.

CHAPTER ONE

‘Weakness will find any excuse.’

– Arven Rauth

I

The augmentician, Janis Gilt, pressed his fingers to Arven Rauth’s throat. He frowned, digging around in search of a non-existent pulse.

The Imperium is a large place after all, and I’m clearly not human, thought Rauth. How long is it since I felt my own heart beat – a year?

As the mortal’s lips shaped ‘twenty’, he withdrew his fingers, flicking them as if to dislodge whatever microbes he might have scraped off under his nails.

Recognising the cue, an indentured aide in a high-necked, tight-sleeved chirurgical gown swiftly presented a towel. He ran it through his fingers, polishing the nails as he looked over Rauth’s corpse-like body once more.

Unblinking, eyes naturally dimmed by a cataract of mucroanid fibres, Rauth stared back.

‘I can certainly certify him dead. Would you like a copy of the documentation, Miss…?’ Janis looked up and over the wire rim of his spectacles, to address the presence that Rauth could feel behind him.

‘Laana Valorrn,’ came the reply. ‘And no.’

The augmentician smiled thinly.

I doubt whether many bring their real names to this shop. Why does he even ask?

Shaking his head, Janis looked down again. He spread his hands along the side rail of the weigh-in gurney and smoothed his expression, obviously trying not to look as though some prickly off-worlder had just dumped the interred remains of Princeps Fabris the First into his clinic. With a finger, he traced one of the flex-rods that ran from Rauth’s reconstructed left shoulder into the neighbouring pectoralis muscle.

Clammy. Cold. No one acts the corpse like an Iron Hand. Rauth resisted the urge to grimace as the augmentician’s inquisitive fingers moved onto his pectoral plate. Another frown spread across the mortal’s face.

‘I can’t find any ribs.’

‘He is not baseline human,’ came Laana’s curt reply.

‘That I see.’ He checked a readout on the side of the trolley that was obscured to Rauth’s eyeline. ‘Two and a half metres tall. Four hundred kilograms. Even accounting for the augments – and fine work, I must say – that is a lot of muscle for two and half metres of man to carry.’ He looked over his spectacles towards Laana again, as if she were a first year medicae scholar with the impertinence to call out a spelling error. He’ll be regretting that soon enough. ‘I don’t normally ask these sorts of questions. I wouldn’t get nearly the business if I did. But I just have to know, what is he?’

‘Nothing like you and I.’

‘One doesn’t need a House-chartered augmentician to tell you that.’

‘One does not need a House-chartered augmentician at all. But I was told you were discreet.’

He sniffed. ‘You were correctly informed.’

The cramped little triage room that served as Janis Gilt’s front-of-shop was already starting to fill with walk-ins, despite the earliness of the evening. Battered bodies sat slumped in chairs, eyes staring, lips going blue, most of them messed by sharp blows to the back of the head, but Rauth could covertly pick out six stabbings, two shootings, one high fall or high-speed impact and even one natural cause with just a cursory look. Some had been brought in by relatives looking to earn a chit from their grief, others by those simply looking to make a chit. They all looked impatient. The heightened Imperial presence in Fort Callivant had seen the value of black market meat rise exponentially.

Locating one of the myriad underground dealers that supplied the Fort Callivant Mechanicus with cadavers had been the easiest part of this mission.

Janis Gilt simply had the distinction of being the unlucky one.

‘I can offer you…’ The augmentician spontaneously removed his spectacles, then quickly reset them and began fiddling with the temples. ‘Twenty-five guilders,’ he declared suddenly, his voice going high as if he were asking a question rather than stating a price. A big man plastered in cult tattoos seated nearby spluttered on a cup of hydrous recyc.

‘Thirty-five,’ said Laana.

‘Agreed!’ Janis snapped, then beamed. He probably would’ve gone to five times that and considered it good business.

‘On one condition.’

The man’s face fell. ‘Go on.’

‘The body contains certain implants. Unique technologies. Things that could be traced back to my employer if a person were so inclined. She insists I witness your procedures and ensure their safe return.’

The augmentician gave the unseen woman a second scrutinising look. Rauth tried to imagine how she would seem to a man like him.

A girl. Nineteen years old. Unhealthily pale. Dark hair, cut to the scalp. She had come dressed in the garb of a serf from some minor House. It would have been a perfect disguise if not for the tough musculature that the Callivantine fashion for short-sleeves exposed. Wire-trace lines of musculoskeletal enhancement accentuated the definition. And there was a tattoo on her bicep. Rauth remembered it well, of course.

A white hand. And the Gothic numeral ‘X’.

Fabris Callivant was a long way from the trade routes and established warzones. Off-worlders were a far from common sight here.

‘I understand perfectly,’ Janis said.

A clap of his hands brought servitor assistance over from its position in waiting. Rauth remained motionless and staring as the gurney swung around and thumped through a set of doors at the back of the shop.

Unlike the grim state of the triage room, which was an extension of the street, Medicae Janis Gilt took pride in his theatre.

Every surface had been swabbed. Every drill bit and scalpel edge glinted as though astringent lighting and daily counterseptic polishes brought out their keenness. The overhead servo-arms and the Militarum-grade diagnostic kit must have been painstakingly acquired, and was almost as good as anything enjoyed by those with the favour of House Callivant. High-end weaponised augmetics and artificial brains, sub-intelligences coded with crude battle algorithms, lined the shelves in bubbling jars of cyborganic fluids.

The servitor hauled Rauth into position under the spot lamps. Chirurgical arms locked the trolley’s wheels and it departed with the same unthinking thuggishness with which it had arrived. The lights slowly burned their outlines onto Rauth’s retinas.

Yet he still didn’t blink.

‘Now then,’ said Janis. ‘You can begin by telling me exactly where I can locate your employer’s devices, and then you can collect your thirty-five guilders from my–’

‘This room is sound-proofed, isn’t it?’ said Laana.

‘It is. Most people don’t want to hear–’

The door clicked shut as she leant her back against it.

Rauth felt saliva building up in his mouth.

Finally.

II

Blood and bone fragments splattered his face, followed shortly after by the incinerator stench of lyddite, fyceline and vaporised brain matter. Arven Rauth drew it in through his nostrils and opened his mouth for more. Blood sloshed through his bionic heart like degreaser through a promethium can. It ached. As if the muscles and nerves it was attached to were constantly on edge, and never more so than now, waiting for it to beat.

‘You could have just wrung his neck.’ Laana hadn’t reacted to the shot. Blood speckled her disguise, and the stone-cold features of the Medusan cult assassin inside them. ‘Why did you have to shoot him?’

Because I wanted to. Because I like the sound my bolt pistol makes, the way it rings in my ears, the look on his face as the back of his head exploded. Because I– ‘Be quiet and lift him for me.’

With a grunt Rauth slid from the gurney, muscles clenching, the augmetic sinews in his arm whining after the prolonged spell of inaction. He towered over the mortal woman, twitching and bulging. Laana looked up, controlling her fear well.

‘I am not your menial,’ she said. ‘You lift him.’

Rauth imagined spraying the assassin’s brains across the tiled wall. The chirurgeon had a bodyguard, madam inquisitor. There was nothing I could do. ‘Your temple should have indoctrinated you better.’

‘Some of us must work for what we have. We cannot all be elevated by genic sorcery.’

My bolt pistol just went off in her face. It must have offended the Omnissiah in some way. I cannot imagine how.

‘Weakness will find any excuse.’ A light nudge sent the assassin stumbling, clattering into an instrument trolley, and Rauth bent down, taking the dead augmentician by the sopping ruin of his throat. He hauled him up to eye level as though his hefty weight were nothing.

The man’s height was average for an upper House male. His toes dangled around Rauth’s knees. His age was more difficult to judge as Rauth had become accustomed to functionally immortal beings for whom flesh was a distant, abhorrent memory. If he were compelled to guess, then he would have put the augmentician somewhere in the final third of his years. Fatty tissue hung from his gut and from his arms like a poorly measured raiment. Too late to return to the tailor now. The weight caused the flaccid neck muscles under Rauth’s single-handed grip to stretch.

The head was a stringy mess, like something forced through a mincer. Humans. So fragile. And yet, it was something like this that he had been born as, and some residue of it would always tar him.

‘What was that?’ Laana’s voice distracted him from his thoughts.

‘What?’

‘You just licked your lips.’

‘I did not.’

‘I assure you, you did.’

‘Then why ask the question?’

She scowled as though a mongrel had bitten her hand. ‘I told the inquisitor she would have been better sending Khrysaar.’

A sudden growl caught them both by surprise.

‘You won’t speak of my brother,’ said Rauth.

Laana retreated to the door, hand slipping behind the back of her dress to the not-so-secret pocket and the collapsible needle pistol hidden between the shoulder blades. Rauth shook his head as if to knock loose an unwelcome thought and turned back to the corpse. ‘Go. Discourage anyone from entering.’ She drew her hand from between her shoulders and presented the open palm. As if an Iron Hands Scout would not have been able to disarm her the instant the intent to draw had entered her eyes.

‘I will give Inquisitor Yazir what she wants,’ he muttered, as Laana backed through the door to the triage room.

He sniffed at the augmentician’s burst head. Despite his lack of a pulse, he could feel his eyes begin to throb. He closed them, lips lowering, lowering, and sank his teeth into the soft, pulpy flesh. His eyelids flickered as the recollections of a life not his passed across them.

He bit down, tearing off a chunk, and swallowed it without chewing.

The omophagea organ in his throat trembled with stimulation. The images intensified. A life. A family. A baby girl, growing flicker-book fashion into an adult daughter. Rauth knew he must have once had such memories. He thought of his mortal parents often, though less than he once had, but he could no longer remember what they had looked like or even their names. Ferrus is my father’s name. A god who abandoned me ten thousand years before I was conceived. Seeing these things reflected through a mortal’s eyes meant little to him now, and affected him not at all.

He sank his face into the red meat, gorging beyond that which had mattered most in life to Janis Gilt, to the specific memory that Rauth and the inquisitor sought.

He saw bodies.

Crudely augmented and weaponised, garbed in the surplices of lesser baronies and local syndicates and arrayed for combat. They were in a sealed chamber, crowded with people, sitting and standing in tiers. The walls were metal, hung with banners, a parody of the great open air tournaments hosted by House Callivant, the Icon Mechanicus glowering down upon them all. A Mechanicus enclave. But there was something untoward about the symbol, something Rauth had seen somewhere before. It scratched at the walls of his subconscious, but Janis had seen nothing odd in the symbols, so Rauth, gorging on his memories, could pinpoint no reason for the gut wrench of unease as he re-saw it a second time.

The remembrance moved on.

The buyer.

Crimson robes swaddled him. Or her. With the Adeptus Mechanicus you can never tell. A wriggling apparatus of limbs was mounted on his hunched shoulders. An array of lights, all to the right side of the face, pierced the darkness of his hood. A voluminous sleeve fell away, revealing a hand bound in gooey red bandages as the magos deposited a credit wafer into Rauth’s – into Janis’ – palm.

Rauth inhaled the charnel stink deeply.

‘There you are…’

III

It was raining when they left the clinic. As far as Rauth could determine, it always rained on Fabris Callivant. A soaring profusion of tanks and guttering carried the run-off from the tower tops down through a labyrinthine maze of pipes, clacking through gates, sloshing past wheels, spilling over a cobweb of locks and bubbling up through grates in the pavement as if the city were in the last days of dissolution.

Nose wrinkling, he toed aside the sacks of cyborganic refuse tied up in the alley across from Janis’ chirurgery to uncover his armour. The rain rinsing his naked skin of blood, he began pulling it on.

The dark carapace had been shiny once, a long time before it had come into Rauth’s possession. It was so weathered now it was essentially grey. Even the clan and Chapter icons had been worn away. Cullas had told him that it was just plates of armaplas and did not have a spirit as power armour did. What does an Apothecary know of it? But he had been reassured that his wargear would not return the offence at some later date.

Sheltering in the clinic’s doorway, Laana calmly disassembled her needler. Then, throwing a raincoat over her bare shoulders, she jumped between the oily puddles to join Rauth across the street.

‘Ready?’ Her hands fussed with the coat as though drawing out the creases, while surreptitiously adjusting various concealed holsters.

‘You are remarkably clean,’ said Rauth.

‘I dislike mess.’

‘I remember.’

He looked up. The mucranoid coating of his eyes meant that he did not need to squint as the warm rain, which was sick with pollutants, battered at them. Most were industrial aerosols that had accumulated over thousands of years, but his enhanced sense of taste could draw out the specific exhaust traces of eight different classes of Imperial and Mechanicus atmospheric fighter craft and of the Hospitallers’ gunships. His worn carapace creaked as, letting Janis’ blood sluice from his face, he rolled the neck joints. He could just about see the lights in the distant tangle of sky, dimmed by the rain as if by a mist, false stars in the daytime. He wondered if it was the Lady Grey, but it was too far even for his eyes to see.

‘I would never have thought Adeptus Astartes daydreamed so much.’

I would never have thought you could irritate me so much. ‘Let’s go.’

Fort Callivant, despite the militant aspect its name implied, was a city of one hundred and eleven million souls. Vehicles ploughed down its wide highways at speed, the ejections of groundwater streaming over the sides of the glass barriers that protected the pedestrian companionways as though they cut through fast-flowing rivers. The glass was stained with the proud imagery of ancient times, but like everything on Fabris Callivant, they were terribly, achingly, old. The colours were gone, the images faded into the glass and rain. Battlemented hab towers, as vast and pockmarked as any mainline battleship, funnelled the downpour through criss-crossing tiers of road and footbridges. Miniature hurricanes summoned by freak microclimates ripped at sodden banners, creaking and groaning their way between ancient buildings. Weathered gargoyles sneered down on pedestrians and vehicles both. They clutched cogs in distended paws, or were clad in chains, representing the shackling of man’s bestial nature by good order and reason. Yet the rain made them dribble and leer, and no one looked up or cared.

Laana hurried over several footbridges, always rising, Rauth always a step behind, shoulders hunched. A rich off-worlder and her abhuman bodyguard. It was a role they had rehearsed many times. As had Laana and Khrysaar. No one challenged them. In spite of the endless gush of Callivantine citizenry, nobody wanted to walk too close to Rauth.

At the next ramp up, they found a squad of Guardsmen blocking the road off with a Chimera. The Guardsmen watched in a huddle as local enforcement checked the identity chits of those being let through on foot.

The off-world soldiers wore royal-blue uniforms overspilling with gold braid, starched and stiff as the men inside. Buttons shone. Lasguns were meticulously handled. Peaked caps dripped, causing the padding in their shoulders to flag. The Chimera too was such a parade ground-perfect blue it looked as if it had been sprayed to the road surface. None of them had any place on this miserable globe. Too perfect for the war coming their way. A Mordian Armoured Fist squad. Eleven regiments of that world had been deployed to Fabris Callivant, but their badges and insignia marked them as Third Squad, Ninth Platoon, 74th Company of the Mordian XXIV Armoured.

One of the local enforcers, a short, hefty man in a black flak vest, stern lines and a grazing of facial hair visible beneath the green slate of his half-visor, leafed through Laana’s soggy papers. A shotgun hung from his shoulder by the strap.

Rauth considered each of seventeen ways he could crush the man against the wall and beat his comrades to death with his shotgun.

‘What’s going on?’ Laana asked.

The man cursed under his breath, flapping the wet off the papers and holding them up against his wall light, the occasional nervous glance thrown in Rauth’s direction. ‘Minor skirmish. Nothing to worry about.’

Laana covered her open mouth with her hand, a poor affectation of an anxious feudal slave, but the man’s mind was occupied. ‘You’d think the Frateris Aequalis had trouble enough with the invasion.’

‘I don’t pretend to know what goes through their minds,’ the enforcer grunted, returning her papers. They were perfect. Naturally. ‘Last tram to Machenv leaves in twenty minutes. You don’t want to miss curfew.’

With icy sweetness, she thanked the officer.

‘Keep your hand on your shotgun,’ Rauth grunted, as he followed her through the checkpoint. The enforcer stiffened and immediately clasped his weapon to his body armour.

My bit for the war.

The bridges on the other side of the checkpoint benefitted from superior weather protection, more of the same time-dimmed pictorial glass presenting the hammering rain with scenes of Imperial Knights in war and peace. Laana shook off her coat.

One section of wall and half the road had been cordoned off by more armed enforcers. Investigators picked through the debris of what looked like a high-speed pursuit and its terminating crash. There were tyre scuffs in the road, a spray of bullets riddling the weatherproofed glass. In the middle of that arcing spray of fire, a Cog Mechanicus had been stencilled over a faded diorama of a Knight of House Callivant, while a force of Iron Hands battled what appeared to be a horde of Legiones Astartes depicted as a many-headed wave of serpents.

I know this, realised Rauth. The Heresy War. The 34th Clan Company of Clan Morragul, ‘the Brazen Claws’, garrisoned to Fabris Callivant in payment of a debt and largely spared the fires of Isstvan for their sins. A servitor was air-blasting the graffiti from the glass. Only the human half of the icon remained. It was on the wrong side. Rauth could have dismissed it as the ignorance of the artist but something about the symbol struck him as subtly, deeply wrong. He frowned, an itch in his skull, trying to remember where he had seen such an emblem before but could not.

‘The Frateris Aequalis,’ Laana said, then spat.

The assassin skipped up a set of stairs wide enough to accommodate a thousand. Mirroring the native Callivantines, she shrugged her raincoat back on, splashing up the waterfall that cascaded down the stone steps.

Rauth strode up after her. The steps bore out onto an open plaza, busy still, but less boisterous for being open to the full flurry of the elements.

A network of landing pads of various sizes spread out like balanced plates, criss-crossed by walkways and disrupted by the occasional fortress spire. Bulk lifters powered down and hauled up. Mono-task servitors loaded, unloaded, refuelled, gave directions to the occasional bewildered off-world clerk and drove laden pallets of materiel to and fro. Men in rain-soaked tabards waved fluorescent paddles, becoming part of the chaos rather than conductors of it, caught helplessly in a flow of soldiers that churned through rain-pummelled spumes of coolant and promethium exhaust.

Rauth made a warning noise in the back of his throat, almost dislocating Laana’s shoulder as he dragged her behind a pillar plastered in weather-sheeted instructional leaflets.

A pair of colossally armoured Space Marines emerged from the grey. Their armour was the lifeless white of a dwarf star, with an aureole of gold. The dense plates were inscribed with scripture and verse. On their left pauldron, the red Hospitallers cross was emblazoned. A morbid array of symbols including hourglasses, skull-embossed shields and aquilae filled their right. Rauth presumed they denoted squad and company allegiances, but if the Hospitallers were a Codex-compliant Chapter, they certainly made it difficult to interpret it from their markings. I don’t suppose that I care. Even with their ambling, platform-shuddering walk, they outpaced the flesh-and-blood soldiers that surged about them.

They clumped past Rauth and Laana’s hiding place.

‘Wait,’ Rauth hissed in the assassin’s ear, as though arguing over one of the edicts on the message pillar. I don’t need to try hard to look argumentative either. He could only assume that the Hospitallers’ senses were as sharp as his. Sharper even, with the advantages of Mk VII power armour. Inquisitor Yazir had gambled that a neophyte Space Marine offered the advantages of a mature Space Marine without attracting as much of the attention.

Rauth knew it wouldn’t fool the genuine article.

Once the two Hospitallers had sunk back into the rain, he let out a relieved breath and nodded.

‘Come on. I can see the comms station.’

The structure that Laana took them to was a squat, square-walled building, a bunker in all but name, with a small transceiver dish gathering rain on its flat roof and a flickering lumen sign above its door. It was the ward communications hub.

It was busy inside too.

Suddenly tense, he hunched his shoulders and entered first.

It was the crowds. They made him uneasy. The bubbling churn of several hundred human beings existing in the same place all at once, the sweet floral-base aromatics they applied to disguise the stench of their flesh, the static charge of cheap fabric rubbing against cheap fabric. He hated it. Rauth had lived his entire life, but for brief, explosive episodes, in an armoured box shared with about a dozen others. Medusa was an inhospitable desert, its one city essentially emptied for most of its year.

His training with Sergeant Tartrak had taken him off-world more than once, of course, but never to a world like this.

Everyone looked so… weak.

He spent a few unimpressed seconds scanning the room, his bristling presence quickly emptying it of those without actual business to attend, while Laana sidled into the queue for one of the comm booths.

With all the signal traffic dicing the near-orbital bands, raising the Lady Grey from a portable vox-device was one step back from impossible. The Hospitallers in their power armour could have done so easily, literally with the blink of an eye, but Rauth was not so fortunate. He scowled at the thought. After the battering Clan Borrgos had taken on Thennos, full status as a battle-brother was almost assured as soon as the inquisitor released him and Khrysaar from her service.

The idea excited and sickened him in equal measure.

After a short wait, Laana picked up a handset. She punched in a few numbers, followed by her identity chit. The terminal clicked through a sequence of keys as it established the required connections. She held it to her ear, absently watching the rain. Rauth listened with crossed arms for two minutes until the assassin mutely passed him the handset.

The voice on the other end had been warped by passage through a vox-distorter, but was recognisably female. ‘Laana tells me you saw where the bodies are being sent.’

‘Not exactly. It is not Exar Sevastian, but in one of the chirurgeon’s memories there is a figure that I recognised from the picts you provided. One of his senior adepts, perhaps. I don’t know his name, but I would recognise him if I saw him again.’

‘A fair beginning. Did you see nothing else?’

‘They were inside. A Mechanicus facility. Big enough to hold a lot of people.’

‘That does little to limit the search.’

‘There was a lot to take in,’ Rauth snarled. ‘There might be more still to come to me.’ He was quiet a moment, a faint itching in his metal hand. ‘Do you still think Sevastian is the one the Voice of Mars gave it to?’

‘I am certain of it. Exar Sevastian and Nicco Palpus’ fates have crossed too often over the past half millennium. Furthermore, Sevastian was with Kristos on the world you call Columnus. His holdings there were destroyed utterly. It is my supposition that Sevastian will have earned a return to favour here only by Palpus’ grace. It is safe to assume that Sevastian owes Palpus a turn of the wheel.’

Rauth grunted. The inquisitor had her own way of speaking, constantly slipping into peculiar metaphors and magniloquence.

‘The only question is where to find it. Catching Sevastian is like catching your own shadow.’

‘And you think these illicit tournaments are where to find him?’ Rauth shuddered. ‘Cybermancy. A fighting pit for glorified servitors?’

‘Every being has its vice.’

He gave a snort. Not every being. ‘Give me a few hours. I’ll find him.’

‘No. Fort Callivant will shortly be under military curfew, and I do not wish to antagonise local enforcement if I do not have to. Threaten officers with rosettes and talk will follow. The next thing you know you are hunting Exar Sevastian’s noosphere ghost.’ Rauth gave a reluctant grunt of agreement. ‘In any case, I want Khrysaar to take over from here.’

‘But he–’

‘I want Apothecary Mohr to check you over again.’

‘I’m fine. And all I have is a visual description of an adept. The memory is in my head.’

The voice on the end of the line hesitated. Just a fraction of a second. ‘No. I need one of you or Khrysaar under Cullas’ observation at all times.’

Liar.

Rauth blinked, unsure what had brought out that thought with such venom.

‘Yes, inquisitor.’ The phantom itch in his bionic hand had become intolerable, and he scratched it against his thigh carapace. He glared around the handset at Laana as though she were the cause.

‘The shuttle is waiting at Pad Theta. Do not linger. I have received a communication that leads me to fear that Kristos is aware of our presence, assuming the coming invasion has not already tipped our hand. Things are about to get very complicated, very soon, and with complication comes opportunity.’

The line went dead.

CHAPTER TWO

‘Their resistance only illustrates their illogic.’

– Magos Qarismi

I

There had been a time when Draevark could access simulus for a split-second inload and emerge ready for battle in moments. As the centuries had worn by, he had noticed it taking longer to inload the same quality of information. His recovery times had lengthened too. Apothecary Haas had charted it. He was currently averaging twelve and a half minutes between termination of simulus and full combat awareness.

>>ALERT>>

He looked groggily into the synesthetic jumble of cross-wired senses. Messily rendered figures danced and teased and bled colour, an intermediate breed of figment, neither an artefact of the mind nor a product of external stimuli. Something in between. They were tall, approaching a Space Marine in height, but freakishly slender. An abstract art form. Tall helms enclosed their faces. Their firearms were as inscrutable as the runes etched into them: no trigger mechanism, no power source, no ammunition feed that threat analysis wetware could understand. Powerblades, mirror swords and lightning spears shone with a lethal perfection.

A banshee shrieked through his brain, forcing coherent thoughts onto slower side paths of myelinated fibres rather than the newer of plastek and copper. Something about the warriors was intrinsically blurred.

>>ALERT>>

But they were warriors. That he could see.

His reflection melted across armour scales of alien plasteks. A tombstone of black ceramite and plasteel, riveted, corded by cables, a vulturine helm with a grilled undersection that seemed to be screaming, screaming.

He looked away, disoriented by the psychotropic effects of after-simulus.

Revivification runes streamed through his enhanced vision, the flitting forms slowly beginning to disintegrate, erupting into a storm of pixels as though vaporised by blasts of optical plasma. Others did not discorporate so completely. Morphing, as opposed to simply atomising, shrinking and bulking out, shedding outer skins like alien caterpillars giving rise to hard, machine-bitten mortal men.

The Iron Hands serfs stood bent over consoles, stabbed sullenly at control slates, criss-crossing each other without ever speaking as they moved from post to empty post. Their eyes had the hollowed-out, socketed look of men who had seen horror and could no longer be moved by it. They wore black uniforms over hard, vat-graft muscle.

A Catachan might be bigger, a Mordian more precise, a Kriegan more willing to toss his pathetic life into a bullet at his lord’s command, but there was no man in the Imperium colder.

No planet bred survivors like Draevark’s.

>>ALERT!>>

The Alloyed spoke to him, forcefully, and this time he heeded. He read the screed as it spilled over his optic inputs.

>>>PURGE OF THE SUNRISE HERALD > ELDAR > SUB-DESIGNATION ‘ALAITOC’ > 009411.M37 >>> SIMULUS CANCELLED >>> ALERT >>> PRIORITY ALERT >>>

With a hiss of gurgling hydraulics, he twisted his head. An alarm flashed against the hooked beak of his helmet. The image of a bounding eldar warrioress skipped across his synapses and he mentally flinched. His metallic body was incapable. He purged his optics and reinitialised. The banshee fled into his subconscious like a bad dream. Something deeply organic screeched in bitterness and pain as a nerve spike withdrew. There was a scrape and a rattle as the adaptor plug unhooked from his armour and flailed about within the confined space of the simulus alcove.

Freezing vapours scented with revivifying salts from the sands of Mars blasted his battleplate as he staggered from the alcove.

A mass of Mechanicus adepts pursued him. Their wire-threaded robes churned the heavier-than-air condensate into something boneless and grasping. Draevark ignored it, and them, as they sanctified his ancient Tactical Dreadnought plate with holy oils.

‘Report,’ he snarled.

‘Shadow-class eldar cruiser, seven-five-five, forward.’ Sergeant Artex’s voice was a brash monotone, compounded by a sullen echo, as if it had been relayed through his battleplate by the Alloyed itself. The five battle-brothers of his demi-clave stationed on the command deck regarded Draevark emptily. They might have still been in simulus themselves for all the reaction they gave.

‘Exactly where Kristos said it would be,’ Draevark murmured.

‘Position and heading precisely as the magos calculi predicted,’ said Artex.

‘After eighteen months of waiting, I was beginning to suspect Qarismi had divined this one incorrectly.’

‘How does it feel, I wonder,’ said Artex. ‘To devote your obscene existence to the manipulation of fate only to be exposed, now, by the powers of the calculus?’

‘I wonder what else the calculum prognosticae reveals,’ Draevark muttered darkly. ‘The importance of this vessel, for instance, why one ship should justify a fleet of ours sitting idle for so long.’

Artex regarded him hollowly. ‘You emerge from simulus bitter.’

‘It is a heavy weapon to wield.’

‘Which is why we wield it. We will become stronger for it.’

In melancholic agreement, Draevark looked up to the main oculus.

The alien ship was impossibly delicate, a bauble of gold wire and frozen glass spinning through an infinite gulf of space. The Pariah-LXXVI sun was a single pin amidst a mess of scattered stars. The sunlet’s dim white light prickled the intricate contouring of the alien vessel’s hull, a feeble ripple across the bi-dimensional weave of its photonic sails. The sidereal wobble of the webway portal to which it ran disturbed the star field twenty million kilometres off its elegant bow, a nascent shimmer as it drew its sails. For a second, the eldar ship appeared to drift under the star-shadow of her pursuers, inertia alone turning her with an inhuman elegance that the tech-priests of the Alloyed could never match with thrusters. Then it caught the wind. Sails ripped taut and in the switching of an optic cycle, the slender vessel had gone from near-static to hyper-velocity. It cut between the strike cruiser Brutus and her escorts. Strobing pulsar beams stripped the larger vessel’s void shields, and it was aft of the Imperial warships, leaving them to chase its holo-ghosts before any of them had the chance to return fire.

Typical Clan Borrgos, too keen to get in close.

Cross-referencing the eldar vessel’s shape and markings through the Alloyed’s xenoglyphic archives, Draevark arrived at an eighty-four per cent profile match.

Isha’s Spear.

The vessel had twice been engaged by the Clan Morlaag destroyer Tempered Claw in late M35. Alas, in the wake of the Moirae Schism, the Tempered Claw had been incorporated into the fleet of the Sons of Medusa Chapter and had taken its more detailed simulus recordings with it. Pity. Assimilated insights and tested tactics, proven over nine thousand years of conflict between the Alaitoc Craftworld and Clan Garrsak, trickled into his active memory. A generic tri-D schematic mapped to his visor display, underlying the oculus view of the eldar vessel with internal architecture calculated from the Sunrise Herald and a hundred other previously boarded ships of its approximate class.

In anything approximating a stand-up fight, the Brutus had the firepower to see off three eldar vessels of its class. The eldar knew that too, of course, and Draevark begrudgingly respected them for acting accordingly.

‘They will attempt to flee,’ he said. ‘When challenged with overwhelming force an eldar will, in ninety-three per cent of recorded cases, attempt to flee.’

‘Agreed,’ said Artex.

‘I am glad you agree, brother. Does the interlink convey my gladness?’

A pause. ‘No.’

‘I am glad.’

The remains of Draevark’s face scrunched in pain as his system tethers drilled the command layers of the clan interlink for the locator signals of his claves. Ident-runes blistered his optical display. Thirty warriors of Clan Garrsak. All of them clustered around the embarkation decks except for Artex and his demi-clave on the bridge. With the absolute authority of a captain’s codes, he could cut into closed vox-links, hijack visual feeds, monitor his warriors’ vital signs and even shut them down if he so wished. On this occasion, he did not impose any further.

The Alloyed carried a full third of the clan’s strength. And his was just one ship.

His authority carried little weight with the propriety codewalls of the Clan Borrgos cruiser Brutus and her escort flotilla, but he knew that a further two full claves would be manning their embarkation decks.

Of the strength carried aboard the Omnipotence, he had no notion at all, but it would be great. The spirit of an Ironbarque would slip anchor with nothing less.

‘Weapons to full charge. Align forward matrices. Load boarding pods, but hold launch for my command.’ Draevark flexed his claws. His gauntlet knuckles yielded with a string of arthritic pops. He looked down at them, a grossly unsubtle action in Terminator plate that caused metallic joints to squeal and servo-muscles to pull. ‘The body tires. It grows stiff with age.’

No one answered.

The handful of mortal slaves, the serially networked bridge servitors and even the warriors of Clave Artex; for all the vaunted collectivism of the Garrsak, they existed in separate worlds.

‘Do not forget Iron Father Kristos’ demands,’ he growled. ‘Obvious hull damage is to be minimised where possible.’

‘Aye lord,’ answered the ranking slave.

‘Instruct the Brutus to shadow our heading, escorts to adopt a holding formation. As though we mean it.’

‘Aye, lord.’

Draevark’s gauntlet clenched. ‘Prepare for boarding.’

II

‘The eldar retaliate,’ said First Sergeant Telarrch, observing the unfolding void action from nineteen simul-captures implanted throughout the Iron Hands flotilla and interpolated noospherically to his mind. He felt sufficiently qualified to tender the supplemental opinion: ‘Unexpected.’ As he watched, the Brutus manoeuvred to hold the alien ship at bay, the eldar vessel making full advantage of her mobility and speed to minimise her exposure. The escorts were drawing back into their holding formation while the Garrsak Clan cruiser Alloyed came in, drives running at one-tenth, taking no chances.

‘Their resistance only illustrates their illogic.’

Magos Qarismi had assumed a meditative pose within a petalled arrangement of runebanks and displays. They showed a concatenated stream of infinite power series and regressive algorithms light years beyond Telarrch’s ability to comprehend. The magos’ face was an aluminium skull, decalled in precious ormolu with numeric sigils of rank and the blessings of the cog. Frost glitter highlighted the orbits of his eyes and the ridge of his cheekbones as he turned, offering Telarrch the unasked-for courtesy of eye contact.

‘Adherence to the calculus ensures that commitment to action is made only when victory is beyond statistical doubt. The eldar should recognise that defiance can only result in defeat.’

Telarrch did not understand, but he did not need to.

He had followed Kristos from the beginning. He had been first to submit to cerebro-reconditioning, had rejoiced as the Iron Father’s Librarians had burned his mind even of the memory of weakness. He recalled nothing of the time before Kristos. The names of the officers and Iron Fathers whose failures had preceded Kristos’ elevation were gone from his mind. His life began in the conditioning chambers of the Omnipotence. Kristos was Clan Raukaan. He was the Iron Hands.

Telarrch was privileged to be given this opportunity to obey.

Kristos desired the alien. Telarrch did not know or care why. Kristos would have the alien.

‘Despatch overrides against the Alloyed’s and the Brutus’ code barriers. Assume direct control of the Garrsak and Borrgos targeting grids.’

The subservient machine-spirits that inhabited the Omnipotence’s command deck chirped and whistled as they responded.

The void-borne fortress-monastery of the Raukaan Clan was a behemoth from a prehistoric age, built with fading arts in the ember glow of the Horus Heresy. Only the main oculus and the handful of active consoles lit the ice that glazed the empty workstations. The labours of cogitators and thought engines were all that warmed its innards above the absolute chill of space. The grating chirrup of their operations echoed about the cathedral-like emptiness that the last mortal crewman had abandoned half a millennium before. At every third or fourth station, a servitor performed the manual operations that the Omnipotence could not. The lobotomised cadavers were bug-eyed and blue-veined with the thick antifreeze fluids that sludged through their circulatory systems, serially down-cycled husks of slow decay in a spider’s web of plug-in ports and trunk cabling. Despite the preservative, the deoxygenated atmosphere and the cold, the biological units reeked of formaldehyde and old neglect. Three Iron Hands stood sentry, stalagmites of plasteel and ceramite in the form of augmented post-transhuman warriors.

With a groan of plasteel and a deluge of code the Omnipotence’s antediluvian spirit informed Telarrch that she had assumed command of the fleet’s weapons. She had no master. She had no crew. After five centuries under Kristos’ stewardship, she would tolerate neither now.

‘Launch gunships and lace them into the matrix,’ ordered Telarrch.

The Omnipotence responded affirmative.

With enough kilobrains bent to the task, the Omnipotence would be able to out-cogitate the eldar’s holo-defences. Such was the might the Omnissiah granted to those who would embrace it.

‘Alert all teams to launch the pods as soon as the xenos enter range.’

‘Without prior disablement of point defences, I calculate that one pod in five will be lost.’

Telarrch absorbed the magos calculi’s update. Only with perfect foresight could the incidental be sifted from the providential, and logic dictated that Telarrch’s foresight was not perfect. He was not Kristos.

‘Acceptable.’

III

The launch rune painted the inside of Jalenghaal’s boarding pod red. It turned his warriors’ battleplate an insipid purple, as if there were not quite enough colour to spread between them. Only when the light found the silver of edge trims or clan sigils or the bare metal of bionics did it return the red in full. No one moved. They were weapons, waiting to be taken from their bracketed wall slots and used, as curious of their wielder’s intent as a power fist. They were Garrsak, and Garrsak obeyed.

Of the nine of them, only one had even marked the optical alert at all.

‘Are you going to respond?’ asked Borrg.

Some physical manifestation of the neophyte’s gross arrogance conspired to make the powered armour he wore appear even more immense than it was. Its high gorget was studded with metal rivets, hung with chainmail and swallowed his unhelmed head as high as his too-wide eyes. They made him look on edge, ready for anything, eager for it even. Just the sight of that much pale, naked flesh made Jalenghaal feel spoiled, as though a grain of dirt had found its way inside his armour. He looked pointedly away, preferring to review the tactical inloads from Draevark and the other sergeants that cycled through his interlink tethers.

The iron captain was expressing some angst over the responsiveness of the Alloyed’s weapons arrays.

‘The Brutus has already launched boarding craft,’ Borrg went on, seemingly harbouring the – for once – inaccurate impression that no one was listening.

Jalenghaal knew that the neophyte had been owned by Clan Borrgos and it would have cost Clan Garrsak dearly in recruiting rights and resource to claim him after the losses they had endured on Thennos.

How Jalenghaal would have liked to have been privy to that cost-benefit calculus.

‘I see from the interlink that two demi-claves of Tartrak and Castan are already aboard and engaged,’ said Borrg.

‘Don’t let those implants go to your head, neophyte,’ grumbled Burr.

Jalenghaal turned slowly.

His second was built like a drop pod, all shielded pistons, belt plating and bracing struts. He had been rebuilt after Thennos, as so many of them had, stronger than he had been before. But if Burr realised he had made a joke, then he did not show it. Jalenghaal let his disapproval fade into the shared system link.

‘Let the Brutus strike first,’ he said, dismissive. ‘It will increase our chances of success. And survival.’

Borrg’s brow furrowed. It was possible he claimed some remote mortal loyalty to his intended clan, but he was Garrsak now, and Garrsak obeyed. He nodded, his face almost vanishing behind his studded gorget.

‘If it is glory or honour you crave then you should have died mortal.’ Jalenghaal wondered if he had ever blood so hot, before he had drained it, replaced it with synthetic carrier fluids and encased it in iron. His memory told him no, but it would not be the first omission it had made in two hundred years. ‘War is binary. Success or failure.’ He looked over his clave, motionless still, aside from the occasional muscular twitch from Borrg. Jalenghaal’s armour spirit demanded status reports from theirs and they complied, runes splayed across his display in a scrolling hierarchy of long service and rank. He asked the question, nevertheless. ‘Is everyone prepared?’

‘Prepared,’ said Burr.

‘Eighteen months of inaction is not ideal preparation,’ said Strontius.

‘A long time to wait on one eldar ship,’ Borrg complained.

‘Does your flesh ache?’ said Deimion.

‘My flesh hungers for battle’s knife,’ the neophyte spat back.

Thorrn, a bulky warrior with a vaned helm that resembled a robotic aquila and the broken outline of a rare Mk VIII powered suit, gave a grumbling sigh. As with Borrg he had been bought by Clan Garrsak at a price, but there the similarities ended. The last augmetic vertebra in a lengthy forgechain was the acid-etched adamantium of the Avernii. He had not taken ‘demotion’ from the veteran company well.

‘Activate the rune already.’

Ignoring the implied challenge in the veteran’s tone, Jalenghaal reached out to punch the launch rune.

‘Wait.’ Lurrgol had been staring at the floor as though determined to catch it in a lie. He looked up, swaying side to side with the mounting urgency of the boarding pod’s spirit as he scanned his brothers’ faces. ‘Where is Kardaanus?’

Jalenghaal stiffened. ‘Kardaanus is dead, brother.’ Lurrgol appeared to accept that and fell quiet again.

Was it grief, this pain that came every time he had to reprise this conversation?

It felt like a broken rib used to feel, a dull throb somewhere between his secondary heart and pared-back digestive organs. Part of him wanted nothing more than to carve that section out and replace it with something inert, but another part, the part that felt grief for his brother, could not. The feeling was not for Kardaanus, for he had died on Thennos in battle with the traitor skitarii. His components had been distributed amongst the clave. His progenoids had been harvested to transform the next generation of neophytes to follow Borrg and his peers.

Kardaanus would live forever.

His grief was for Lurrgol.

‘How can he be dead if I can still hear him?’ Lurrgol whispered to the deck plates beneath his boots. ‘He is still exloading. Can you not hear it? Is it only me?’

The clave shared a look between them.

‘Kardaanus is dead, brother.’

With that, Jalenghaal punched the launch command.

The boarding pod shook like a beast unchained. The noise intensified as its rocket turbofans built to full burn. He heard what sounded like a snatch of a hymn through his helmet vox, or perhaps two overlain, Iron Chaplain Braavos girding the faith of man and machine both, before his audial implants enabled auto-lockdown routines. He was left with a strangled whine that lasted for a few seconds. Then nothing at all. Just the steady tick of his cybernetics at work, echoing in the sealed confines of his helm.

Odd. How discomforting the reminder of one’s own cyborganic functions could be with mortality so near.

The rocket turbofans unleashed their full fury in an apocalyptic blast that shook the Alloyed to her spine. At the same time, the magnetic clamps holding the pod in place switched polarity and launched it into the void.

The Iron Hands shook in their brackets. Lighting blinked, while weapons and kit rattled in stowage, in hands, across knees. Jalenghaal’s secondary heart started to beat, a squelch-squelch thumping in his iron breast. He hardened his grip on his bolter, pressing its brick muzzle to his thigh plate with the other hand. He could not remember the last time he had possessed a sebaceous gland, or felt true anxiety during an insertion, but old habits died harder than flesh. Harder even than old warriors.

The telemetry that the Alloyed fed to his helmet stuttered, pixelating, then vanishing altogether as the boarding pod sped violently from its cage. One isolated scroll of numeric symbols stood out from the mess.

Six thousand kilometres –

Four thousand –

Two –

<Omnissiah bless this instrument,> canted Thornn.

‘Ave Omnissiah!’ Jalenghaal replied, and loudly, not with feeling but because forward proximity sensors had just activated the pod’s magna-meltas and he had to shout to be heard over the roar.

Then ninety-five tonnes of metal propelled at two thousand kilometres per hour struck liquefied alien plastek.

Warriors slammed sideways into their brackets as the boarding pod tore into the eldar’s lightweight hull and did not stop there. Squealing, shuddering, it crashed through the alien superstructure until, with a furious lunge, it pitched to a halt. Jalenghaal’s helm chrono clocked a half-second respite as the warriors were flung back the opposite way and the brackets disengaged clamps.

The forward hatch blasted off. Bent sections of it clanged into the alien ship.

Jalenghaal rose.

In a whir of motorised joints his clave followed suit, a rattle of scrapes and clicks as sickle magazines were slotted into bolters and pistols, the tooth-throbbing hum of Kardaanus’ – Strontius’ now – lascannon hooking in and drinking power. Eyes wide and vitally hungry, Borrg ignited his flamer, something feral about the play of flame over his gorget and of shadow over his scarred face. He had left his helmet in its slot.

‘Wait,’ said Lurrgol, last in line at the back of the troop aisle, bolter hanging in one gauntlet as he surveyed the row of apparently unfamiliar faces between him and his sergeant. ‘Where is Kardaanus?’

Jalenghaal raised his bolter to his chest plate and, without a word of instruction, charged down the open ramp.

Hostile xenos, at least, he knew how to deal with.

IV

Rage filled Elrusiad as the carved geawood doors to the central nexus sundered before a terrible blow. The panelling split up the centre, the diorama of Hoec Charting the Outer Heavens splintering like so much worthless kindling. The hardwood beneath was splintered and frayed, ultimately coming apart itself under the armoured boot of a towering barbarian.

His armour was matt-black, struck with grey where shuriken and blade had savaged the primitive paintwork. His lensed eyes were shot through with silver light, his helm grilled like a muzzled beast. It issued bestial machine snorts as he stamped through the wreckage of the door. Coils of ribbed cabling wound his barrelled chest, the armour there thickened on one side by the addition of iron bands that doubled as attachment sites for the immensity of a mechanical left arm. Every movement was preceded by a torturous whine of powered assistance. Monosyllabic iconographs of iron skulls and toothed wheels adorned his brutality in silver, glittering like casting runes as the enfilade of scatter lasers and shuriken cannons lit him up from above.

The Space Marine strode through the heavy fire, unperturbed, the black heart of a ricochet storm that tore out what remained of the door and the mosaic floor, yet failed to induce so much as a misstep in the heavily armoured warrior.

Then he raised his gun.

Explosive shells shredded the light cover offered by the balustrades ringing the galleries, defacing the heroic statues that looked on in helpless dismay. More warriors crunched through the shattered door frame. Five in all.

Eldar guardians returned fire from behind the wraithbone carvings that lined the way, the pace of their retreat set precisely by that of the intruders’ advance. The staccato burst of primitive firearms was an operatic score, the screams, explosions and the shredding dismantlement of works of art the crescendos to its dramatic movements. It enraged Elrusiad’s warrior spirit, virtually lifting his feet from the floor as he delivered a challenge he could scarce hear for the pounding of blood through his ears.

He drew both pistols from their holsters, shuriken and vibro-beams adding to the withering storm engulfing the iron mon-keigh.

Screaming a war cry of her own, Laurelei gathered a charge of the bridge’s guardians to meet the massive warrior on the stairs. Even with the spirit of war thumping through his veins, Elrusiad resisted the impulse to join them.

To go hand-to-hand with such things was to court not Khaine but Ynnead.

The guardians engaged with master-wrought swords and shuriken, but the first warrior did not break stride. Nor did he accelerate. He simply strode through them as though assaulted by high grass. A guardian screamed as he went down under the giant’s boot. Another broke against an elbow. A third blew apart from the inside out. The precious blood of an ancient race decorated the barbarian’s armour. A sound burst, something like laughter, grated through his facial speakers.

Laurelei danced aside, as graceful with a blade as a Harlequin performing the Dance of Death. The Space Marine could not hit her and did not try. He strode on, leaving the warrior following to obliterate her with an automatic burst.

What fell of her could barely be described as meat.

Elrusiad felt no grief, for he was War now, and war made only corpses.

With a cry, he held his weapons’ psychic triggers down, until his mind screamed. Tears of blood rolled down the psychoplastic of his warrior mask.

He staggered back from the steps, diving under a jewel display as a retaliatory blaze of bolt-fire burned the tiles where he had been standing. He slithered behind the wraithbone housing as bolt-fire chewed into it from the other side. He looked up. Plaster dust and lightweight plasteks drizzled from the wounded galleries, ripped banners flapping, abandoned weapon platforms lying like corpses. At least a dozen guardians were still firing, largely ignored now as the intruders pushed on the central nexus.

War did not know fear.

Psychically replenishing his weapons’ charge, he rose from cover and fired.

+Fight, Ishanshar,+ he pulsed. +Arouse the ghost legions. Drive the mon-keigh into Ynnead’s embrace.+

The enemy commander too was distributing orders. Gunfire blazed from behind the curve of stairs and scraps of curtain. The leader directed his warriors onto secondary staircases to attend the galleries with garbled blurts of sound.

Elrusiad read the crude Imperial glyph-markers on his armour.

His name was Tartrak.

War knew War.

The geawood steps creaked under his titanic weight. For the first time since he had donned the face of the Bloody-Handed God, it dawned on Elrusiad that the Ryen Ishanshar was lost.

The only victory left to him was to warn Autarch Yeldrian.

He backed out of his cover, ignoring the bolt-fire that burst around him to return a volley that would at least slow the brute down. Shuriken rattled off the Space Marine’s armour as though Elrusiad had emptied a pail of gemstones over his helmet. His fusion pistol proved more effective. The beam of vibrating particles sliced through the warrior’s shoulder on a rising angle, front to back, the weapon sagging in a suddenly dead arm.

The Space Marine lifted it one-handed and resumed firing without missing a beat.

Elrusiad spun aside, the prismatic trail of afterimages left by his crystal cloak leaving Tartrak blazing through phantoms as he ran for the farspeaker circuits.

His fingers brushed jewel displays, laying hands on quiescent terminals, rousing them to a nervous flutter of illumination. Only the dead held their stations now, and their wraithsight had seen their doom long before Elrusiad had acknowledged its inevitability.

They were afraid.

‘You are adept at fleeing, xenos.’ Tartrak’s voice was like an anvil being dragged across a bed of nails. He hammered a bolt shell into a neighbouring jewel display. The ensuing detonation showered Elrusiad with nacre. The ghost mariner bound within the farspeaking circuits issued a plaintive song, a glimmer of gem lights that spoke to the permanence of death. ‘And when you run out of galaxy, what then will you do?’

Elrusiad did not lower himself to arguing with the primitive. He set his shuriken on the slope of the console, slid his fusion pistol into its holster and lay both hands to the mind interface.

He could do this by will alone, but he needed to be swift.

+Yeldrian.+

Barely had his mind formed the word when he felt a tingle walk across his skin. Like invisible ants. He looked at his hand and saw that the fine hairs were drawing tall. He looked up sharply to see a horrendous stain on the air. Several more were taking shape across the central nexus dais. His mind offered up another word.

+Surrounded.+

With lightning reflexes, he snatched the shuriken from the table.

Thunder detonated, and bruised reality split to disgorge another giant in encasing black armour directly onto Elrusiad’s dais.

The adornments to his armour were different. The enormous shoulder plate displayed a triplet of pentagons within a tooth-wheel. Layers of chainmail fell from it, down the arm, the uppermost layer studded with onyx and black agate, silver ringlets interspersed with black iron to form a repeating mathematical pattern. His hand was acid-etched steel and gripped a shuddering chainblade almost half his own great height in length. At the chest, he stood wider than three Elrusiads, the spread-winged idol that men called ‘aquila’ overlaying the machined plate. It was white, brushed with silver highlighting, one avian half replaced with a clawed, skeletal machine likeness. His helm was scored and antennaed, a string of heavy studs, long-service markers of some kind, drilled into the forehead. Elrusiad counted five.

It took the warrior a moment to process his new surroundings, lenses flickering and the occasional arc of empyreal wychlight streaming across his ornate warplate.

Elrusiad drew his fusion pistol and fired.

The vibro-beam melted through the warrior’s breastplate and erupted bloodlessly from the back. The warrior looked down at the melted aquila, then lifted his gaze, bolt pistol rising with it, and returned fire.

The volley of shells went straight through Elrusiad’s holo-cloak and into the farspeaker circuits. The Navarch gasped, spinning instinctively from the source of the fire, only to catch the ensuing detonation in the face.

The blast screwed him twice around before dropping him to the floor several lengths from where he had been standing. His right leg buckled under him and went dead. Broken. His aspect mask cracked as it smacked side-on into the tiles. Blood of no vein pooled under the break, and his heart tremored as he drew his fingertips through it, tracking the psychoplasmic vitae over the floor mosaics.

His focus wavered as the destructive emotions the mask had been holding at bay welled up and bled out. Anger. Terror. Laurelei! Real tears stung his eyes, but he clenched his jaw against the flood and forced himself onto his back.

The warrior towered over him, staring in confusion at the twinkling holo-lights that fell with exquisite slowness from the air, optical echoes of the scale pieces that rained from Elrusiad’s torn cloak.

Gripping it with both hands to stay its shaking, Elrusiad aimed his fusion pistol up.

‘Deliver this to She Who Thirsts, mon-keigh.’

The excitation beam carved a straight line of distortion from the nozzle of his weapon to the underside of the warrior’s chin. The Space Marine’s helmet simply evaporated, the roof bursting in a splatter of oily liquid and foul smoke. His knee guards slammed with bone-breaking weight to the floor, either side of Elrusiad.

Then he began to topple forwards.

Weapons forgotten, Elrusiad folded his arms protectively over his face, scrunched his eyes, and with desperation rather than defiance, he threw his thoughts at what was left of the farspeaking circuits. There was no time to compose a message. What had already been thought-sent would need to suffice.

+Eldanesh falls.+

His mind was mercifully absent as a tonne of ceramite pulverised his mortal remains.

V

Jalenghaal waited for Kristos with his brother-sergeants. One hour and eleven minutes after Jalenghaal had reached the bridge, the Iron Father entered.

The tech-adepts that Magos Qarismi had despatched to pick over the bridge’s technological wealth hastened from his path. Many would have served the Iron Tenth all their lives. They would have experienced the unquiet whispers of machine-spirits slaved to a transhuman shell. They would have known the raw physicality, the powered whine, the thumping presence of the Adeptus Astartes. Some may even have followed the example of their lords, flensing their neural pathways so that emotions such as fear or abhorrence travelled slowly if at all.

Kristos gave them pause.

Solid metal boots clanked on the alien mosaics as Kristos strode between the unsettled adepts.

A pair of lightly built skitarii sentinels stood guard by the steps, upright grasshoppers in bio-augmented carapace and compound visors. Their robes were red. The energy-damping weave absorbed the already low levels of incident light, making them appear unnaturally dark. Sigils of the Adeptus Prognosticae and the Iron Council winked amidst the stygian folds. They lowered their arc rifles and saluted as the Iron Father mounted the steps, maintaining that rigid pose long after he had passed as though their joint servos had been frozen.

Jalenghaal was still waiting when the Iron Father reached the top. As was Sixth Sergeant Coloddin. As was Tartrak of Clan Borrgos.

‘Never trust,’ the Scriptorum read, and flawed though Ferrus Manus had proven, the Iron Hands and their successors had learned the lessons of his betrayal well. The eldar were all dead. The skitarii had been deployed to watch the adepts, the Iron Hands to watch the skitarii.

Vibrantly coloured transparent shards exploded under the weight of up-modified Terminator armour as Kristos ascended to the central platform.

The sergeants did not salute – they were Iron Hands – but their wargear emitted a blizzard of welcome and submission phrases. Jalenghaal resented his systems’ complaisance, and manually modulated the auto-exloads with a micro-second delay and subtextual antagonism signifiers. Kristos did not appear to notice, but he noticed. Kristos saw all. Narrow slits for ten optic lenses glowed icily around the black iron of the Iron Father’s helm. That, coupled with the free rotation of his helmet about the neck socket and the reversible pointedness of his shoulders, elbows and knees rendered concepts of orientation obsolete.

Disregarding the three sergeants, at least from active senses, the Iron Father looked down at Telarrch with a squeal of angling optic slits. An unstable stasis field covered the Clan Raukaan First Sergeant and the fragile remains of the eldar he had fallen upon in an on-off buzz of blue static, cast from an array of portable projectors. A pair of Apothecaries attended.

Niholos did not bother to look up. A variety of replacement parts, bionic and organic, hung off belts and hooks riveted to the Apothecary’s armour, battlefield spares released from the Omnipotence’s cryostores, as well as high-value components repatriated from the fallen during his egress. Most dripped fluid of some description. He was bent over Telarrch’s body, emitting click-pulses as he prodded the first sergeant with the elongated probe-talons of one hand. He was attempting to raise Telarrch’s armour spirit, but it made him look even more like a vulture cawing over fresh carrion.

The second Apothecary did look up. Scanning telescoptics backlit by their own deranged glow whirred and whirred as if struggling for a point of focus, sense vanes ticking and purring like corroded clockwork. His armour displayed no deliberate record of age, which many Iron Hands, who obsessed over such metrics, took as further evidence of the Apothecary’s instability.

Jalenghaal was two hundred and one years old. Kristos was six hundred and ninety-eight years old. Dumaar was said to have been ancient when the Iron Father had been mortal.

Kristos was not the first to have sought to pry the Apothecary from Clan Borrgos over the centuries. His skills as an Apothecary and durability in battle were without compare in the Chapter. The depth of his lore was second to none. But he was also thoroughly devoid of ambition except where it pertained to his own physical correction.

And he was mad.

Lobotomisation or death was what befell the weak; Dumaar was what became of those who thought they had the solution.

‘He lives.’ Dumaar’s voice emerged from his helmet grilles like radiation from a cold transuranic shell. Jalenghaal knew he would have announced ‘he dies’ in the same tone, as subject to nuance or circumstance as the Universal Laws.

‘Barely,’ Niholos returned. The servo-arm built into his power plant whined and clanked as it modulated the field output from the stasis emitters. It continued to operate, even without the Apothecary’s direction. ‘Remove the stasis field and Brother Telarrch will die.’

Jalenghaal watched the exchange in silence. He had heard of the cerebro-reconditioning that the warriors of Clan Raukaan endured, barely one full step from lobotomisation, in his opinion. Clearly, his position within the Chapter apothecarion spared Niholos such treatment.

Dumaar emitted a savage burst of audio, his own bastardisation of binaric and, as far as Jalenghaal could discern, another two archaic machine forms.

‘Then do not remove the field.’

‘You were first on the bridge?’ Kristos asked him.

Dumaar’s external optics clicked as they cycled, but he said nothing.

Niholos shook his head, exasperated. ‘Let him go, warleader. His augments will rebuild many damaged brothers. The surviving elements of his clave have already submitted their intentions regarding certain components.’ The cannibalisation of fallen brothers for parts to be shared among kinship groups was a ritual that promoted intense loyalties and rivalries both. Jalenghaal thought of Lurrgol, before brutally purging the mental pathway. ‘They may need to fight again soon,’ the Raukaan clan’s Apothecary continued. ‘If your intentions for this ship proceed as prognosed.’

‘They do thus far.’

‘Irrelevant,’ Dumaar announced. His optical objective visibly widened its aperture to encompass both the Iron Father and his rival Apothecary. ‘Your ultimate intent was not to capture this ship, but to capture the individual it was dispatched here to engage.’ It was not a question. Kristos’ silence was not an answer. ‘You possess adequate strength without recourse to…’ Dumaar’s vocabuliser emitted a blurt of content-dense binaric before slipping into an entirely new strand of Medusan. Jalenghaal’s heuristics managed to identify it as Rokahn, the (he had thought extinct) dialect of Clan Felg ‘… ill-advised corrective surgery.’

‘Interesting advice,’ said Niholos. ‘Especially from you, Dumaar. The paragon of ill-advised surgeries.’

Dumaar looked down at the body under the stasis field. ‘Seventy-two per cent of brain matter destroyed. Unsalvageable. Injuries consistent with a melta-type weapon discharged into the cranial space. Irrelevant. Amniotic transfer to permanent cyborganic support functions can be achieved with less than ten per cent of subject brain function remaining.’ He turned back to Kristos. ‘Calculate thirty-six per cent probability of irreparable insanity resulting in brain death.’

‘Interesting advice,’ Niholos said again. ‘Coming from you, Dumaar.’

‘Can he be interred?’ Kristos asked, an optical flicker indicating that his full attention was now on his clan’s Apothecary.

‘It is not impossible, but the recommendation is baseless. Clan Raukaan has no sarcophagi to spare. Let him perish, warleader.’

‘And Clan Borrgos?’

‘Negative,’ said Dumaar.

In a whir of servomuscular bundles and a crunch of reorienting joints, Kristos redeployed his monstrous frame to face Jalenghaal.

‘What of the Garrsak Clan?’

The sergeant hesitated. Dislike bled from his tethers and into the noosphere. It was not even a conscious act now. The Iron Father had been responsible for the deaths of Vand and Ruuvax on Thennos, and had cost Burr and their former sergeant, Stronos, highly in flesh. If Kristos had been involved in the uprising as Stronos believed, however indirectly, then he was culpable for a great deal more. His thoughts turned to Lurrgol again, and he frowned. Thennos would not be the last time that two clans of the Iron Hands settled a dispute with arms, but Jalenghaal did not even know why the Iron Father had been so determined to crush the skitarii revolt without Clan Garrsak’s involvement.

The discrepancy rankled.

‘The Ares sarcophagus remains unclaimed,’ he said, carefully. ‘But a nine thousand year-old relic is not something we will willingly barter away.’

To you, were the words left prominently unsaid.

‘Your sentiment is unworthy of you, tenth sergeant. Look around.’

Jalenghaal did as he was bidden, noticing an enginseer in the indenture brands of the Borrgos clan as she snapped picts of a toppled statue.

‘One being’s relic is another’s scrap tech,’ Kristos continued. ‘Clan Garrsak has been crippled by the need to recruit and resupply. I will instruct the Alloyed’s astropathic choir to petition the Iron Council. Your Iron Fathers will see the benefit of a trade that will lift you back into contention with the other middling clans.’

‘Stronos would never–’

‘Kardan Stronos is not an Iron Father.’

‘Not yet,’ Dumaar echoed.

‘Have Telarrch stripped and placed in permanent stasis until the sarcophagus arrives,’ Kristos ordered the two Apothecaries.

‘Compliance,’ said Dumaar.

Jalenghaal averted his gaze. Garrsak obeyed.

‘There is no such thing as a permanent stasis,’ said Niholos. ‘Even the most perfect systems will degrade eventually. If the first sergeant is not interred soon then he will perish.’

‘How soon?’

‘Impossible to say.’

There was a sharp click of metal on tiles, and Jalenghaal turned his bolter to the stairs, silently angered that he had been distracted enough to be approached unawares.

Kristos, to his annoyance, did not react.

Magos Qarismi scraped his staff with apparent interest through the litter scattered over the alien mosaic.

‘I ordered you to supervise the exorcism of the alien machine’s spirit,’ said Kristos, without turning.

‘The Voice of Mars has given me other instructions.’

‘That supersede mine?’ said Kristos, finally deigning to rotate his torso.

‘An astropathic distress cry has reached Medusa. The logi-legatus had it retransmitted to us.’

‘In the eighteen months we have waited here, I have listened to thousands. What makes this plea worthy of the resources of my clan?’

‘It is Fabris Callivant.’

For several seconds the Iron Father did nothing, but from the directional illumination of his optics he appeared to be looking at Telarrch. Or possibly the eldar shipmaster crushed under his armour.

‘Yeldrian.’

Qarismi’s aluminium skull was locked into a deep-socketed grin.

Jalenghaal watched him, and the Iron Father, and his brother-sergeants. The phrase ‘Never trust’ rang in his mind. There was more at play here than he, or even Draevark, had been made fully aware of.

‘Not this time,’ said the magos calculi.

CHAPTER THREE

‘Innovative… Though I suspect, not one hundred per cent intentional.’

– Magos Instructor Yuriel Phi

I

‘Base systems report rising levels of distress.’

Kardan Stronos heard Magos Instructor Yuriel Phi speaking from the operations cradle, a hanging candelabrum of screen glow and heat-stressed transfer cabling. Smudges of blue-white light in the thick incense smoke were her eyes. Her skin was coated with iron scales. Plug-in cables of various capacitance fell from her recurved scalp like the dreadlocks of a technobarbarian of old, tethering her to the cradle as securely as the profusion of throbbing guy wires tethered her cradle itself to the ceiling.

‘Recommend that you prioritise the primaris generator. At the current rate of increase it will experience catastrophic overload in approximately eleven minutes.’

‘Compliance,’ said Stronos.

The distance to the generatorum controls was short, but crammed with active machinery. The smoke was thick. Like a rag soaked in alchemical euphorics to the face of a doubting pupil. Stronos no longer had an active sense of smell, or taste, and he gave rare thanks to the iron for that. His armour too he had shed, or as much of it as he could whilst retaining the ability to function. Even so, he scraped and squealed towards the array of intestinal cabling and push-button operations on the other side of the pit.

An alarm wailed from a sconce above the subsystem, its flashing light clutched in the mouth of a gargoyle of aged bronze. Stronos could have silenced it with a one-word command, but he could ignore it just as easily. Studying the complexity of plug-ins and panels, he sensed the approach of another and shot a glance over the shoulder.

‘It will take two of us to calm this spirit, brother.’ Barras was a fortress world of frown lines, eyes so deep under dark rings that they could have been excavated from stone. He was three times Stronos’ junior. With his own facial scars and metallic reconstructions Stronos easily made it look like ten.

He turned back to the subsystem. ‘I have this.’

‘It is not a competition, Iron Hand.’

Stronos snorted, replacement lungs forcing cold, oil-tainted air through the ugly metal tube that served him as both mouth and nose. He did not trouble himself to look up a second time. ‘I have this.’ His hand shot out as the Knight of Dorn attempted to reach across him. The knuckled steel of the bionic closed over the other warrior’s bare hand to the wrist. Dashed lines and Medusan numerals flickered across his bionic vision, interfacing with the hand to display applied force and points of stress. He took care not to crush his brother’s radial bone. ‘I have this. Was I unclear?’

Yuriel’s chuckle rattled through the murk like a propeller with a bent blade. ‘Clarification – we are all about to experience catastrophic overload.’

‘Stand by.’ Releasing Barras’ wrist, he set a hand upon the generatorum unit’s body housing, muttering a machine-soothing canticle under his breath as he tapped the meter into the button-push controls.

Somewhere amidst the house fire of girders and smoke, one of the alarms shut off.

He turned his nerveless ruin of a face to the Knight of Dorn. A lifeless expression of petty triumph hung from the metal dermis like meat from a hook. Barras, for his part, bore a bruised wrist and a murderous frown.

‘When we are both armoured brother, you and I will settle this as equals in the duelling cage.’

Dominance rituals. How pitifully organic.

He gave the aggrieved warrior a nod.

‘You have coupled the generator to the overflow regulators of the core cogitator,’ declared Magos Phi, her voice resonating from the smoky above like the voice of the Omnissiah. ‘Innovative, though I suspect, not one hundred per cent intentional.’ For a moment, Stronos felt the bristling flutter of annoyance. Barras smirked and turned away.

The annoyance did not depart so readily.

For one hundred and fifty years, Stronos had served an execrably human Imperium with the conviction that the primarch’s seed and the Iron Creed had combined in the Iron Hands to forge a thousand warriors without peer. How aggravating then to discover only now that there were others in that much-maligned Imperium of Man who were just as experienced, adept and resolute as Kardan Stronos, that his gene-seed in no way predestined him to superiority.

It reminded him of something that his friend Lydriik had tried to tell him.

There are many ways of being strong, brother. Almost as many as there are of convincing yourself you are not weak.

Shrugging it off as he would any irritant glitch in his systems he checked over the partially illuminated display in front of him, rubbing oil-smear from the blinking command line with a finger. ‘Thirteen minutes and thirty seconds to overload.’

‘Hail the machine-touched,’ he heard Barras mutter.

‘A reasonable estimate,’ rattled Magos Phi. ‘But some machines are willing to a fault. They will tell you they can go on when in reality they are an operation from collapse. A Techmarine must know the character of each of his charges in order to see through its claims to the truth beneath. I would put your time closer to twelve minutes.’

If Stronos could have scowled he would have scowled. If his face could redden it would have bathed the machine pit in bloody smoke. Instead, he looked to the rest of his so-called brothers for better news.

Baraquiel of the Angels Porphyr did not even notice him, wholly engaged wrestling with an errant system, the halved blue and white of his robes periodically obscured by vomiting gouts of steam. The mortal priests of Mars held many advantages in piety and dedication, but they could not match a determined Adeptus Astartes warrior for the sheer brawn required to humble a truculent machine.

Thecian, by contrast, was so still he might have been meditating. He was of the Exsanguinators, a lesser Chapter that Stronos would never have heard of had they not been seconded to the same scholam facility. His skin was as bloodless as a serpent’s abandoned skin, mildly luminous even when enfolded by smoke, more a thing of fine marble than imperfect flesh. Every so often, he blinked, skin scraping his eyes like a sharpening stone, but otherwise he did not appear to be doing anything at all. Of them all, Stronos considered him the most difficult to understand.

Even Barras, for all his emotion and fixation on honour, was comprehensible.

The Knight of Dorn, lightly garbed in robes of tan and bone, moved back the way Stronos had come with enviable ease. He stopped at a suffering array of pipes and fed his hands through with a grunt to massage the valves behind.

Sigart, the last of their unlikely brotherhood, would be nearby.

Learning much from Stronos’ failures no doubt.

None of them had yet earned the right to ‘take the red’ or to don the Machina Opus on their gear, but each warrior’s Chapter colours, Stronos’ silver and black included, were overlain with the sleeveless red surplice of an aspirant of Mars. They were here because they were the best of an exceptional cadre of aspirants to the lore of Mars.

Stronos was here because he was an Iron Hand and the treaties between their two worlds demanded it – a fact he would never be allowed to forget.

Excluding the absent Sigart, none of the aspirants had more than a metre or two of cramped and overheated machinery between him and a brother. Stronos found the physical proximity repellent, the insistence on verbal communication disarming, the fact that he could not feel their thoughts or track their efforts through his data-tethers both annoying and deeply, irrationally, suspicious.

Baraquiel disengaged from the radiation manifold and looked up to the thrumming operations cradle. ‘One of us must enter to the generatorum chamber and shut it down manually. I volunteer myself.’

‘Do not look at me, aspirant,’ Yuriel chided.

‘Go,’ Stronos and Barras spoke at the same time, then glared at one another as Baraquiel picked his way back through the mess of exposed machinery and disappeared into the smoke.

Stronos heard a door slide open. He heard it slide shut.

Exactly seventeen seconds had elapsed before the Space Marine’s voice echoed through the chamber’s master vox.

‘The emergency bulkheads are sealed. I cannot access the blasted chamber.’

‘Amputation of endangered sectors is the basic response of any high-functioning gestalt.’ Yuriel offered this in a tone that suggested to Stronos that she may have been examining her cuticle circuitry. ‘I am disappointed that none of you thought to consider this. You have…’ A pause, presumably while she consulted a rune display. ‘…Nine minutes to catastrophic overload.’

Stronos’ armour shuddered and growled, the power servos emitting a noise akin to a Land Raider stuck in a neutral gear. It felt his frustration through intramuscular spikes and point-to-point nervous control, and strained to convert it into action. Lowering his forehead to the generatorum rune display, he instructed his system tethers to lace with those of the interface.

A tremor of violation passed through the connection.

His systems were purposed for battlefield networking rather than machine-to-machine interfacing, and both sets of systems responded with blurts of warning screed, smearing his bionic eye like a weeping infection, as he brute-forced the connection.

<Proceed with caution, Stronos.> Stronos had no difficulty in making out Magos Phi through the smoke now. His awareness impinged upon the noosphere, the parallel reality of raw data and of the Motive Force, and she was incandescent as an angel. <There are entities within the noosphere that will be offended by the encroachment of a mere aspirant.>

And then he felt it.

The scholam facility’s collective cognisance was a bruised thing, hostile and indescribably ancient, self-aware only in the manner of a predatory reptile, but aware of him in that same sense, hungrily aware of their disparity of power.

<You will relinquish the generatorum.> Stronos bombarded the base’s spirit with command authorisations and runes of impeachment, but either he had erred in their construction or the chimeric spirit was too angered to heed them.

It reared large, looming over and enveloping him in this dimensionless nooverse, and seared his mind with a hiss of nonsense static.

<I do not know you!>

Stronos felt his body stagger as his senses were driven from the noosphere, networked systems instinctively shutting down and withdrawing into their armoured shell. Sparks erupted from the interface, the physical manifestation of the base’s anger, and slammed him into the cogitator housing opposite.

Magos Phi’s rattling laughter rang out from above, the percussive thud of sealing bulkheads running through the loose metal flooring under Stronos’ prone body.

He could sense the spirit mocking him.

‘Another set of emergency doors has just lowered behind me,’ voxed Baraquiel. ‘I am sealed in.’

Yuriel added an ironic handclap to her laughter.

‘Believe me, aspirant, you were let off with a rapped knuckle.’

The children of Manus were little known for the speed and incision of their wit, and Stronos was still putting together a response when the alarms abruptly terminated. The main lights hardened to a humming brightness and with a whirring clunk of distressed machinery, extractors came online and began making voluble attempts at sucking smoke into decrepit vents. For once, his gormless features expressed precisely the emotion he would otherwise have expected them to convey.

‘What did I…?’

‘A wounded beast will not permit the thorn to be removed from its paw,’ said Thecian. His smile was something a chisel might inflict on a tablet. ‘Even by a caring master. It needs a distraction.’

‘You mean…?’ Stronos felt the infantile urge to tell the Exsanguinator that they could settle this as equals in the duelling cage. Instead, he simply fell silent.

Magos Phi was more effusive. ‘Well done, Aspirant Thecian. And Stronos.’ She peered over her cradle, optics blinking blue-white, on-off. ‘See me after evening prayers.’

Stronos bowed his head. ‘Yes, magos instructor.’

‘And after that you can see me,’ said Barras, grabbing Stronos’ pauldron as he moved past to haul him close and hiss it in his ear.

The Knight of Dorn half climbed through the intervening hardware towards the door. Stronos noticed that it was open, another aspirant wearing ink-black robes under his crimson surplice stooping under and swaggering through. There was a single white cross on the aspirant’s black sleeve, a symbol instantly recognisable to any man in the galaxy.

Sigart.

‘Brothers!’ Sigart strode into the operations chamber, heavily muscled arms spread wide as though to embrace the three of his brother aspirants at once. His grin was almost as broad. ‘Did I just feel the scholam kill Stronos?’

‘Just singed his pride a little,’ Barras grunted.

‘Nowhere he feels pain then.’

Thecian masked a perfect smile behind his hand, but he did not speak. He seldom spoke, unless spoken to.

‘I will improve next time,’ Stronos growled.

‘Meditate on what you have learned,’ said Yuriel, and the five aspirants quietened down and looked respectfully up. ‘Each of you. You will be tested again very soon. Ave Omnissiah.’ The Space Marines aped the gesture, the sacred cog formed from both hands across the chest, and the accompanying refrain ‘Ave Omnissiah’, but only Stronos did so with heart.

Sigart regarded him with an appraising look, as though seeing something he approved of. Stronos was about to ask what it was, but the Omnissiah’s great schema had ordained the rapprochement to be brief.

‘Brothers?’ Baraquiel’s voice echoed from the master vox, ringing with a hollow clarity now that the smoke was being drawn from the augmitter array. ‘I am still trapped down here.’

The scholam spirit turned its myriad forms of attention inwards. Stronos could feel its gloating.

‘Brothers?’

Magos Phi began to cackle.

CHAPTER FOUR

‘Do not stare at the skitarius…’

– Logi-Legatus Nicco Palpus

I

Melitan Yolanis’ breath caught as the elevator began to slow. She didn’t know why. Probably because pretending to be a fully fledged magos in person was a great deal different from pretending to be one in long-range correspondence. Sweat was starting to collect under her palms, and she had to fight down the urge to feel that the dummy implants encrusting her face were still there. Her mechadendrite twitched, nervously. Or maybe it wasn’t anything to do with that at all. Maybe because whatever lay on the other side of the bronze doors couldn’t possibly live up to the expectation she had been putting on it since she had been a girl. And she was afraid. Omnissiah, yes. She was more than just a little afraid.

‘Omnissiah forgive this trespass,’ she whispered, forming the blessed cog and hugging it to her breast as the boxcar eased onto its magnetic buffers with the almost imperceptible bump of precision engineering and flawless maintenance rites. ‘By your will. Your will is the schema. The schema is my action.’ She felt every field fluctuation and resonance anomaly that wobbled through the floor of the car, awesomely aware of the hand of the Omnissiah holding her above a plunging descent on a cushion of magnetic repulsion.

It would take nothing at all for Him to withdraw that favour.

The cherub servitor that levitated incongruously by her shoulder chattered to the door mechanism in short bursts of binaric cipher. The mummified foetus hovered vaguely on the spot, archaic anti-gravitics fizzing and popping from between its in-curled legs. A thumb-sized lens of blue spinel distended one eye socket. The other was stapled shut. As was its mouth. As was its nose.

The unborn child would have been precious to someone once. She wondered who.

She could still remember what it had felt like to be fascinated by such technologies. Before her hair had fallen out and her gums had been poisoned and her lungs had turned black. With an innocence that was the preserve of the very, very, young, she’d thought she could know it all. She’d been four, maybe five years old when her parents had taken her to the crypts beneath the Callivant Forge-Temple. The stones had been old. Twelve thousand years, the magos preservator had told her. The air had felt older. She had felt the power in it, a vibration in her stomach, the taste of iron and excitement in her mouth. Even in the dark she had gawped at the arcane assemblage of coils and pipes and magnets and valves that had constituted the divine wonder of The Princeps, the great plasmic organ of House Callivant. The instrument had been, the magos preservator had told her, a gift from Magos Xanthus of the 52nd Expedition Fleet in commemoration of the world’s return to the Martian fold.

She had peppered the preservator with questions, and then her parents as they had made their weary way back to their hab. ‘How? How? How?’ interspersed every now and then with ‘Why?’

All she could think about was that cherub.

Maybe it wasn’t a human foetus after all. See the elipticity of the palatine structure, the bony protrusions of the themastoid process. A ratling, perhaps. She had only seen one in instructional vellums. She would need to–

The cherub emitted a burst of binaric cipher at the door mechanism.

It responded in kind.

<Welcome, Magos Vale. NL-Primus, Zero Tier.>

The doors whisked open.

Melitan’s heart butterflied about her insides. All her life she’d craved to hear the title ‘magos’ spoken before her name. And now…

<It is addressing you, magos. Do not compromise the identity I have constructed for you before you are even through the door.>

Melitan winced in pain. Conversing with the meme-proxy that Logi-Legatus Nicco Palpus had embedded in her medulla was not a simple matter of speaking and heeding. The implant forcibly rewired her brain cells to convey imagery or words. It hurt. So she said nothing in return, simply nodding to the cherub servitor that she was ready in the hope that the meme-proxy would remain silent.

The wizened automaton was already floating off through the open doors, trailing devotional scripture and electrostatic light.

She took another shallow breath, as though it were a hostage she could hold as insurance, and stepped in after the cherub.

II

Zero Tier was a temple to horrify the believer, a fortress of data to put hesitation into the step of an Adeptus Astartes warrior. Arachnoid figures with artificially bent spines, muttering body parts and the red robes of the Martian priesthood sat hunched over runebanks, gorging, only their mechanical probosces in light. Lensed eyes of disparate colour and type clicked and whirred, focused and dilated, all with the sound of screws being patiently threaded and unthreaded over and over and over. Complex and inhuman mandibular parts twitched as if in physical hunger, lacking only the machine analogue of drool as the rapt adepts parsed the data from their screens.

Even the menacing clank of the prowling robo-mastiffs did not distract the binary infocytes from their screens.

Aside from the neat, ordered runebanks, a whip-limbed magos in heavy robes glittering with numerological symbols presided from a hololithic platform. Bi-dimensional information panes orbited him, schemata and analyses of schemata, mangled by layers of encryption and orders of notation that Melitan had no description for.

But she could guess.

The magos sifted through the maelstrom of arcana fed to him by the infocytes, delivering a cursive homily or canticle excerpt on occasion, employing mechadendrites and gauntlets ending in noospheric claws like a six-limbed nightmare shredding the wings off an endless succession of screaming butterflies.

A single armed skitarius observed.

He was nearly two and a half metres tall, almost as large as a Space Marine, reticulated body armour a slab of black. Denial codes and exload inhibitors enveloped him in a cloak of technical obfuscation. Melitan’s implants, even some of the better-quality forgeries, made consistent attempts to scrub the skitarius from her conscious awareness. Even the robo-mastiffs, sensoria-packed snouts drawing continuous samples of the adepts’ auto-exloads, clumped straight past, unaware.

<Do not stare at the skitarius. Bethania Vale is a magos of intermediate rank having toiled for three decades in the most secretive diagnostic facilities on Mars,> the meme-proxy chided, causing her to clutch her head in stabbing neuralgic pain. <Your augments should be far too extensive for your flesh eyes to pierce its codewalls.>

She scratched absently at the irritation under her ear and mumbled under her breath. ‘Yes, master.’

Melitan dropped her hands to her lap, adopting the pose of haughty serenity that captured her idealised vision of a genuine adept. An image of Logi-Legatus Nicco Palpus came to mind as a perfect model. She almost sighed. The original, physical, iteration of the Voice of Mars had been far more supportive. Almost fatherly. A charade, she was belatedly coming to appreciate.

The cherub blurted noise at her. Fortunately, Palpus had seen fit to provision her with genuine augments sufficient to decode the binaric as, <Remain.>

The foetus drifted towards the skitarius.

‘You look nervous.’

Startled, Melitan turned towards the voice. One of the hooded infocytes made a crooked contortion of his non-emotive exo-features at her. A smile, and more chilling than the blinkered indifference she had become accustomed to as a menial enginseer.

‘I…’ She considered denying it, but realised there was little point. She was a terrible liar, so thought it best to cleave as near to the truth as possible. ‘Maybe just a little.’

‘Exogenitor Oelur is not as fearsome as his reputation.’ The infocyte’s hooded optics twinkled with unexpected humour. ‘Or his appearance. You will live out the hour, I think.’ There was a ripping sound, the click and snap of disconnecting bundle fibres, and the infocyte withdrew a bi-clawed hand from his runebank and extended it towards her. ‘Numeral Four.’ He leaned in conspiratorially, lowering his voice to a whisper. ‘But you may call me Salient.’

Melitan took the infocyte’s unjointed metal hand in her human one. She almost gave her real name. ‘Vale. Bethania Vale. Magos biologis.’

‘The Dawnbreak Technology will not disappoint, magos. Quite the opposite.’

Salient extricated his claw from Melitan’s hand. She noticed a thin line of blood smeared across her palm. ‘You’re bleeding,’ she said. But the infocyte had already returned to his runebank and slotted himself back in.

She rubbed the blood onto her red robes, a robo-mastiff sniffing her for trace corruption as it growled towards her. She fixed the machine with a glare of such aloofness that any magos would be proud, even as she cringed inwardly, but it detected nothing. It clanked along its programmed patrol without pausing. Tension bled off her.

The infocyte was already ignoring her again, so absorbed in his data that she wondered if she had imagined the entire exchange. Nerves could do strange things.

She looked at the red stain in her hand.

<Attend.>

Without looking as though she was hurrying, she followed the cherub servitor. The foetal slave hovered across the guardian skitarius, neither acknowledging the existence of the other and drifted towards a second bronze door. This one was framed on either side by dark, reflective panels that looked like monodirectional glass.

She could feel her heart beating in her mouth.

Here it came.

III

No one had prepared her for the smell.

There was a certain odour one automatically associated with the inner demesnes of the Adeptus Mechanicus: oils that were particularly pleasing to the inner workings of the machine, blessed greases, the tang of the Motive Force, the buzzing friction of a thousand artificially moving things. All of that was present but almost a pomander musk to cover a sickly sweet something else. It was rejuvenat, formaldehyde, anti-rust, all in cocktail with some mordant element whose aroma she could not define.

With a crunch of gearing and a wheeze of telescoping parts, Exogenitor Louard Oelur beckoned her in.

The gesture might have been reassuring had the proffered limb not been twice her length and three times her girth.

She shuffled towards the desk that divided the chamber in half. The flat surface was panelled with screens. Images and screed or both together flickered across thirty or so runebank monitors, too rapidly even for most augmetic eyes. To her, they simply appeared to stutter from still to still to still. Too quickly for her to interpret. The light they cast was jerky and unsettling. A small icon of the Cog Mechanicus held down one corner of a papyrus roll, almost as an afterthought, a gargantuan mechandendrite pinning the opposite end.

‘Obese’ was a spectacularly organic word, but it applied.

The exogenitor appeared to have accrued augments and subsidiary systems over – it was rumoured – a dozen centuries. The habiliments draped over his expanded bulk were almost a ritual courtesy. The head atop the heap of bionics was a spoiled lump of uncounted restorations and upgrades. A gross secondary head leaned listlessly from the communal neck, gazing blankly at the table. To Melitan’s creeping disgust, it was not an artificial brain but an actual human head. Excision scars and electoos, crystal implants that laid out the schema for future bionics, were still visible on its flesh. She arrived at the unpleasant realisation that this was at least partly responsible for the smell.

She glanced quickly away, ready for the sting of neural pain, but the Palpus meme-proxy had nothing to say.

How did he get in here? she found herself wondering. It certainly wasn’t through the door. And where had the head come from? A slave, a criminal, a heretek? Not a servitor, obviously. What would be the point?

As her thoughts ran on, Oelur remained a constant source of motion. Robes rustled. Servo-limbs and dendrites clicked and wittered semi-independently of the core mass. Unseen components clanked and crunched and chittered and moved, like a tarantula digesting a beetle. When he finally spoke, the anti-climax of a human voice almost broke her nerve.

‘Your journey from Xanthros was comfortable, Magos Vale?’

‘Q-quite comfortable. Th-thank you.’

‘You are suffering an audio glitch, magos.’

Melitan squirmed under her fraudulent robes and equally fraudulent augmetic mask.

‘It has been a long journey, Exogenitor Oelur.’

‘Louard.’ Mechadendrites fumbled along the walls. Clicking. Snapping. As though discussing her amongst themselves. ‘Titles lost interest to me exactly seven hundred and forty-three years ago. My desire for the fawning respect of my inferiors lasted only marginally longer.’

‘L-Louard then, exogenitor.’

‘There is that glitch again.’

‘Apologies exo– Louard.’

‘Do you know how many biosectionists are currently at work within Tier Zero, Magos Vale?’

‘I don’t.’

‘None. Do you know how many adepts of any kind have been recruited to Tier Zero without first working through the subsidiary research levels during the three hundred and nineteen years of my stewardship of NL-Primus?’

‘I… don’t.’

‘I suspect that you can guess, Magos Vale. Know that I will not tolerate dissembling. It is an affront to the good order of the Omnissiah.’

‘None, exogenitor.’

‘None, indeed. Nicco Palpus resides half a galaxy from Mars, and yet his reach is such that any door is opened at his command.’

‘I am fortunate.’

‘I know why Palpus sent you, magos.’

Louard’s robes suddenly bulged forwards, and a rotten, bloat-swollen arm emerged. The calcified fingers tapped with surprising dexterity at one flickering subscreen of his rune display. The alien calligraphy it had been displaying for a fraction of a second vanished, replaced by what appeared to be Bethania Vale’s personal file.

Louard’s two heads examined it together.

‘Five years with Xenoanatomist Tantrun. Ten with Teratotechnologist Coronus. Then fifteen years under Metachirugeon Garadesius at Xanthros, performing extrapolative dissections of xenos 27814σ.’ His primary head looked up. ‘I am not familiar with xenos 27814σ.’

‘I don’t think they exist anymore.’

‘Iron Hands?’

‘Iron Hands,’ Melitan agreed. ‘They tend to be thorough.’

‘That explains how you came to the notice of Nicco Palpus. Indeed, you are fortunate.’ He dismissed the file with a swipe of his rotting paw. ‘You are to assess the Dawnbreak Technologies. You are here to assess me. Do not attempt to deny it. According to my mnemonic archive I have already disclosed that I dislike dissembling.’ The secondary head creaked up on its neck muscles and stared glassily at Melitan. ‘You possess the requisite skillset to analyse the containment procedures of Tier Zero. I can assure you however that no exload-capable unit is in operation within the quarantined spheres. Organic trial subjects are terminated and disposed of under strict control. Even indirect contact with the xenotech is a breach of base protocols. I can compile a list of those adepts who have conducted the most thorough probes of the data, or would you prefer an algorithm to select subjects for vivisection at random?’

‘Exogenitor, I–’

‘I assure that all will be as the logi-legatus requested when he submitted the eldar technology to my safekeeping. I am aware of what occurred on Thennos. I comprehend Palpus’ cognitive processes. But this is not some backwater test bed in the Segmentum Obscurus. This is Noctis Labyrinth Faculty Primus.’

Melitan’s eyes, already watery from the lenses she wore over them in lieu of true optics, seemed to wobble. In truth, she had no idea why Palpus had gone to the extraordinary effort to disguise her as an experienced adept rather than recruit a genuine magos with the profile of Bethania Vale. Except perhaps that he trusted her. And she trusted him.

‘He only wishes to be certain,’ she said.

The exogenitor emitted a consumptive belch. ‘I will see to it that he is. We will begin with a tour of Tier Zero, but tomorrow. Your journey has been a long one.’

‘Thank you, exogenitor.’

‘My servitor will escort you to the dormitories. Do not allow the skitarius to disturb you.’

‘W-what skitarius?’

‘That glitch again, magos.’ He gestured to the door with one massively sinuous mechadendrite. ‘Tomorrow then.’

‘Tomorrow.’

The cherub servitor impelled through the open door on a burst of static and Melitan backed towards it, suddenly wary of turning her back on the corpulent data lord. She caught another glimpse of the miniature Cog Mechanicus on the edge of his desk. It was making her queasy, but only as the cherub led her away did she understand why.

It was inverted.

CHAPTER FIVE

‘We all have darker natures, daemons of the soul we would prefer our brothers not see.’

– Thecian

I

‘Put the book down.’

Stronos said it without looking up, his optic focusing in on the fine-detail electronics held between the forefinger and thumb of his metallic hand. Binary ‘yes-no’ haptics in the fingertips reported on pressure as he leant in. His flesh eye strained, stung by the smoothness with which its partnering bionic clicked through its magnifying objectives to bring up the intricacies of the wiring. The eye’s pinprick glow ran down the length of his knife as carefully, carefully, he began to strip the insulating plastek. He could already feel himself beginning to relax, the shame he had felt over his intemperance during the exercise slowly dissipating. Facial muscles that no longer held any nervous authority over a mouth twitched as if to produce a smile.

What would Verrox think?

Fifty thousand light years from Medusa, a hundred years from his Iron Moon, and here he was still working on his penance. In truth, fixing the cursed thing had always been an impossible task. It had become a tool for meditation, an outlet for his errant thoughts and emotions. Sometimes he wondered if that had always been the Iron Father’s intention.

Probably not. Verrox was hardly known for subtlety.

The last of the plastek peeled off under his knife, and only then did he glance up.

‘I said put it down. It is not yours.’

Thecian stood against the wall of their shared cell, robes the dark purple of a spent vein hanging from his broad shoulders, leafing idly through Stronos’ journeyed copy of the Canticle of Travels.

The book had seen more action than some Astra Militarum regiments. The binding was cracked, a las-burn towards the bottom. A few of the pages were starting to come loose of the binding and Stronos could see the indent, present at the exact same position on every page, from the meticulous paging of a metallic hand. Thecian, he noted, had a reading habit of his own, licking his finger before turning each page. Despite the fact that his lips were drier than the Martian brick behind his back.

‘The text is in lingua-technis,’ said Thecian, thoughtfully. ‘Is that not unusual, for a record of your primarch’s life to be composed in the common tongue of Mars?’

‘The original Canticle was oral. Most were lost, others pure myth or evolutions of other tales. The rationalised edition was assembled by an Adept of Mars, almost seven thousand years ago.’

Thecian looked up over the silver-grey illuminations of his open page. ‘It is your basic text and it was written by a tech-priest, in a language only those inducted by the machine cult can understand?’

Stronos returned the look, without the expression.

‘Have you been to Medusa?’

‘I have not had the… pleasure,’ Thecian replied.

‘Or served alongside the Iron Hands before now?’

‘No. Why?’

‘Because you will not find a Medusan, much less a battle-brother of the Iron Hands, who could not teach a tech-priest a little lingua-technis.’

Thecian chuckled. It appeared to come naturally to him. ‘I can imagine the phrases all too well.’ He lowered his eyes back to the page. ‘I cannot make out the marginal text.’

‘That is because you have never learned Juuket.’

‘My loss.’

Neither guided, nor required, to utter anything further Stronos returned his attention to the now stripped length of wire, feeding it into a small circuit box and laying it carefully along a prepared track of polymer adhesive. He pressed it down under his organic thumb, then nicked off the loose end with his knife.

Accustomed by now to his cellmate’s peculiar modes of conversation, Thecian picked up the train himself. ‘You should have trained as a Chaplain rather than a Techmarine.’

‘You would not be the first to say so.’

Stronos closed the finished circuit box with a plastek click and placed it on the prayer table, crunching his cheek muscle into the eye to reverse cycle from high zoom. This was, he realised, more than he had shared with another since his extirpation from Clave Jalenghaal. More than he had ever divulged to a non-Iron Hand. He was not entirely comfortable with the idea. ‘Put it down. It is valuable.’

Thecian shut the book and examined the worn binding appraisingly.

‘To me,’ Stronos continued.

The Exsanguinator shrugged, then tossed the book onto Stronos’ cot. It was undressed. His body’s requirement for sleep had been greatly curtailed, and he was fully capable of a satisfactory thirty minutes rest every few days from a vertical posture.

‘How delightfully illogical.’

‘It surprises you that I value my culture.’

Thecian gave a short laugh. ‘Brother! It surprises me that you have a culture.’ Stronos, again, gave no response. Thecian frowned, crossed his arms and regarded him seriously. ‘When you hear “son of Sanguinius” what is the image that your mind conjures?’

Stronos did not answer – the Emperor’s Angels, beautiful, perfect.

Flawed.

Thecian gestured to his own worldly possessions, the manuscripts, the rows of dressing kits and alchemical vials, the half-formed attempts at art. His forearms, Stronos noted, were criss-crossed with scars both old and new. ‘You have one. Of course you do.’ His voice became dusky. ‘I suspect we are all more complicated than our legends will permit. We all have darker natures, daemons of the soul we would prefer our brothers not see.’ He shrugged, as if the daemon he spoke of had a claw on his shoulder. ‘I would rather not see, but the moment I look away, the moment I let it have that, the daemon wins.’ His lips pulled back over hard white teeth as he regarded Stronos at his prayer table. ‘I think that you and I are more alike than any of our brothers here.’

Stronos grunted. ‘I had actually thought the opposite.’

‘Why do you think I volunteered to share this cell with you?’

‘You volunteered?’

‘The magos instructor felt you should be left alone.’

‘She was correct.’

‘I do not know the life of your father, but I know of his death. I know the… burden… of orphanhood.’

Over the century and a half since his implantation with Ferrus Manus’ gene-seed, Stronos’ ability to pick up on non-verbal cues had waned. If there was something that Thecian was attempting to get at or imply then it was lost on him. The Exsanguinator watched him, however, gauging for a reaction, for understanding, and so he affected the slightest nod, neck drawing on the rigid brace of his forgechain. Had Lydriik not practically begged him to use this sabbatical to broaden his understanding of other Chapters?

He sighed.

Had he not tried?

‘Perhaps you do,’ he allowed.

Thecian smiled, as though acknowledging the magnitude of Stronos’ effort. ‘You lost your temper during the exercise,’ he said. ‘With Barras, with Magos Phi. Even with me.’

‘I am master of my emotions,’ Stronos countered.

‘If it’s me you are trying to convince then do not bother.’ Thecian pulled away from the wall and walked towards him. Suddenly earnest, he crouched before Stronos’ prayer table. ‘You are… not alone in needing to control the daemon within. But there are other ways, brother, beyond mere avoidance and repression. I can teach you, if you will allow it.’

Stronos regarded the perfect, avowedly flawed, being that studied him in kind from the other side of his workbench. He recalled the vows of secrecy that Lydriik had undertaken prior to his duty-tithe to the Deathwatch, and how he had scorned the Librarian for doing so. What are secrets after all, but hiding places for the weak and fearful? The Adeptus Mechanicus had extracted similar oaths from their aspiring Techmarines, oaths that made the demands of the Deathwatch look like a steady eye and a firm handshake, and he had been equally disdainful then too.

But secrets were like rust. A little bit of light, a little bit of air, and suddenly what looked like solid iron was flakes crumbling in your hand.

‘I can be better than I am. That is all.’ He thumped the prayer table, making his tools and cannon parts leap. He was not sure what made him do it, and he regretted it immediately. ‘I am an Iron Hand. I should be…’ He trailed off, looking up at Thecian with his human eye. ‘Better.’

‘Then be better.’

Stronos emitted a sigh, poisonous hydrocarbons rasping from his abomination of a mouth. ‘You do not think at all like an Iron Hand. We seldom commit to a course unless it is certain of success.’

‘Where is the challenge in that?’

‘In choosing the course correctly.’

Thecian laughed. ‘You must miss your own brothers?’

‘No.’

‘No? I feel the absence of my brothers like an ache in my hearts.’

‘As do I,’ said Stronos. ‘But not only in my hearts.’ He pointed to his armour’s girdle plate. ‘This is Jalenghaal.’ To his shoulder. ‘Burr.’ His throat. ‘Lurrgol.’ His hand moved to other points of his armour where, bundled in protective ceramite, a system tether maintained a continuous stream of inload/exload to the ether. Occasionally the name of a fallen brother would escape him, become conflated with that of another who had assumed the battleplate of Kardaanus or Morthol or Vand and who he named now in the same thought even though they had never met. ‘And nor are they absent. Bits and pieces of emotion. The occasional stray thought or voice.’ Jalenghaal’s frustration. Lurrgol’s grief. He shook his head slowly, clearing it. ‘They are in the warp. My impression of them is always stronger when they are in the warp.’

‘Time and distance matters little there,’ said Thecian.

‘Perhaps.’

‘Say “perhaps” one more time, Brother Stronos, and I will withdraw my offered aid.’ He chuckled to himself, shaking his head. ‘In any case, I trust that you are finished here?’

‘Why?’

‘Because you have been in here for over a day, brother. Barras is starting to think you will not come.’

II

Before Scholam NL-7 had been Scholam NL-7, a proving facility for the most gifted aspiring Techmarines, it had served as a resupply station for caravans travelling from Ascraeus Mons to the clandestine watch posts of the Noctis Labyrinth. Before that it had been a drilling outpost, scavenging for trace titanium deposits in the exhausted sands. Before that, a terraforming station, when Mars had been green and mankind had with justification called itself master of all the heavens it surveyed. The remnant archeotech was still in evidence, though it was purposeless, degraded, suffering through heresy and schism and shifts in orthodoxy until it was little more than the icon of a memory.

It reminded Stronos of Meduson, the sole city on Medusa, an oasis of civilisation raised out of unforgiving rock by the pre-Imperial foundations on which it sat.

Most of the scholam was inaccessible now. Entire wings filled with ancient technologies had been sealed off by machine-spirits that thought little of their inheritors or the diminished age in which they now found themselves. Others had suffered breaches as the millennia dragged by and remained exposed to the Martian atmosphere, and haunted too, or so some believed. The bulk of the remainder was a labyrinth of service crawlways and common areas built for an era before the Emperor’s dream of a Legiones Astartes had been born. They were too cramped to see much use now, even if mortal men had apparently once been larger and haler than the malnourished Martian stock of M41.

The hub of the facility (literally in fact, for in flyover picts it appeared as a weathered cog, partially buried in red sand) was a chamber of habitable size. If one were to park two Land Raiders back-to-back such that their rear hatches opened onto one another then the shared troop space would have been about this size.

In its epoch as a mining post it had housed the drill. A vertical shaft still ran through the fifteen or so metres of rock to the surface, and several hundred again down to the unmapped arcologies below. In its centuries as a waystation it had been a calefactory, a place for travellers to wait out the infamous Martian dust storms in some kind of comfort and camaraderie. As a scholam it had become that again.

A low-slung metal table occupied most of the chamber. Adeptus Astartes warriors in monastic garb and aspirant tabards sat cross-legged on the floor around it. A pair of menials in sleeveless red robes quietly withdrew the evidence of an unspectacular meal. Stronos regarded the spread distastefully. His requirement for nutrition had decreased in parallel with the decrease in his organics. The destruction of his mouth and oesophageal tract on Thennos had only expedited that process. Direct electrochemical transfer now accounted for seventy-three per cent of his required sustenance with the remainder imbibed by fluid intravenous drip. His desire for company had never been great, but the unsociable method of ingestion had expedited the diminishment of that mortal craving as well.

This, he sometimes thought, was what it felt like to be a Dreadnought, entombed in iron and dead to the living world.

The prospect of achieving that unrivalled honour thrilled him less and less each day.

‘Begging your grace, lord,’ one of the menials muttered nervously, swerving past Stronos with a stack of pewter bowls. His bare arms were covered in electoos, mapping the schema of the augmentation to which he aspired and was unlikely ever to receive. The low-grade electrical implants flickered badly, hurting the eye and making it appear, just for a moment, as if the Cog Mechanicus on his cheek had been imprinted back to front.

Stronos ignored him, and forgot him the moment he was out of sight.

‘It is good of you to join us, Kardan.’ Baraquiel shuffled around and extended a hand in greeting. ‘I hope you will make a habit of it.’

Stronos stared at the hand. It had taken Stronos nearly two and a half hours to isolate the door mechanism from the scholam’s aggravated spirit and release Baraquiel from the corridor.

With a frown, Baraquiel withdrew his hand.

‘Stronos.’ Sigart nodded to him as he stood. Baraquiel rose too. Between the pair of them and Thecian, they immediately began dragging the table from the middle of the chamber.

Removing it created a rough square, ten metres by ten, the table itself forming one side. Add a power-armoured Space Marine and that hundred square metres disappeared fast.

Add two and it began to feel very claustrophobic indeed.

Barras stood against the far wall, massive in his battleplate of bone-white and brown, his bulk emphasised by his folded arms. Honour seals fluttered from the knee and elbow guards. Unhelmed, his scowling face was underlit by the steady blink of his gorget softseals, his deep-set eyes funnelling ever deeper into shadow.

‘I feared you would not come,’ he said.

‘Emotion is weakness,’ said Stronos, moving to stand opposite the Knight of Dorn.

Having come directly from his technical meditations, Stronos was incompletely armoured. Like Barras he was unhelmed. Several sections of his right arm were un-plated, including the hand, but mechanisation more than made up for the lack of powered strength.

Nothing more needed to be said.

The challenge had been offered and accepted. The arena had been prepared. ‘Honour’ could be satisfied in only one way.

For something held in such high esteem, honour was a vacuous thing. Ferrus Manus had been a being of deep and unshakeable honour, but one crack in it, one perceived crack, had been his downfall. The primarch had feared how his brother Fulgrim’s betrayal would reflect on him. It had been a need to prove his honour, more than any skill-at-arms or guile at the traitor Fulgrim’s command that had destroyed him. What was honour anyway? Every warrior tradition bred its own evolution of the theme, a language of their own, unrecognisable from the root form. Put a Space Wolf and a Dark Angel together and they would agree little on the subject of honour, but victory they would both recognise.

‘Unarmed?’ Stronos asked.

‘You are missing a gauntlet,’ Barras grunted.

‘I am unconcerned.’

‘Very well.’

The Knight of Dorn ground his teeth and lowered his head. Stronos threw his opening punch while the warrior’s eyes were still downturned.

What was honour after all, but a bolt pistol held to a warrior’s temple, his own finger on the trigger?

Barras ducked back like a rearing snake. He caught Stronos’ fist in one big open gauntlet, then dragged him lurching off balance and smashed a knee into his plastron. It would have dented a tank, but Stronos’ chest was heavier than most tanks. Barras grunted in surprise when he was not doubled over, and Stronos barged him into the wall. Martian brick dust hazed them both as the two suits of blessed war-plate rattled and growled, their spirit animus stamping and goring like beasts of war. They untangled enough to swing arms. Stronos mashed his elbow into Barras’ face. Again. The pistons in his arm hissed and banged.

A snarl dribbled from the void in Stronos face as his arm ratcheted back for a third drive. Barras roared, face slimy with fast-coagulating blood, eye socket shattered as though with a mallet, but he summoned enough raw dynamism to drive his weight into the Iron Hand.

Stronos was too massive to be thrown, but was forced a few clumping steps back before his own motors reasserted themselves in a squeal of gears.

Barras was already on the attack.

Stronos let the Knight of Dorn’s fist beat against his chest plate, parried the next with his own gauntlet, a feint, and caught an unexpected jab to the lightly guarded rotator rings between forearm and bicep of his right arm. Something crunched. The joint seized for a fraction of a second as the system’s spirit rerouted damaged pathways, gifting a free punch, which Barras hammered into his bionic eye, followed by a kick to the knee that crushed the servo-motors and slammed the joint to the ground.

‘Have you no shame?’ Barras bellowed, backing up with thumping steps so that Stronos could heave himself up onto both feet.

A voice behind him shouted encouragement. Baraquiel. Stronos filtered it out. His onboard battle cogitator crunched through its data, analysing the Knight of Dorn’s fighting style for bias or weakness and projecting its conclusions with an updated stratagem to his optic display. He pressed fingers to his cheek and looked down at them. They were bloody. Barras’ punch must have cut the bionic into the surrounding flesh and burst a vessel.

‘Only in failure,’ he replied.

Anger made Barras’ whole body shake as he started forwards. Stronos moved at the same time. Barely three strides between them, hardly enough to build up a charge, and the two Space Marines collided in the middle with the glacial inevitability of impacting worlds.

Power armour thrummed, whined and trembled with bone-jarring power as the two warriors fought. Ceramite cracked ceramite with every probe, feint and counter. Evasion was out of the question, and so they pounded on one another. Almost taking turns. More skill to it than met the eye. Every shuddering footfall was an offensive act, the inconceivable mass and power of battleplate making every split-second decision final.

Stronos’ cogitator scrubbed and updated with every exchange as the Knight of Dorn switched his tactics, alternating between at least seven distinct martial forms. Muscle memory made him fast. Stronos struggled to keep up, adopting an increasingly defensive style as his systems sought to identify a pattern. There was always a pattern. Only Chaos was completely rando–

A bone-white fist cut through his guard of calculations and left dented knuckles in his funnel mouth.

Stronos stumbled back, arms out for balance, a flurry of white noise murdering his optic display. His cogitations disappeared under the flood. He felt anger in his flesh, his muscles swelling, a pressure building inside his skull for want of a scream of rage. His first thought was that he had suffered system damage, that some broken valve had flooded his organics with a sub-lethal dose of combat stimulants, but his armour systems coolly reported that this was not so. He was… it took him a moment to diagnose the condition… angry. The buckling to his mouth pipe transformed Stronos’ next outbreath into a propeller-like shriek. He threw his flesh hand as though it were encased in a power fist.

Barras ducked easily. A clumping step took him across Stronos’ chest, and then he rammed his pauldron in to slam the Iron Hand against the wall.

‘Tell me my flesh is weak, Iron Hand,’ said Barras, not even breathing hard. The Knight of Dorn bristled with anger, his deep eyes burning with it, but it was a surface layer, a subsidiary black carapace that energised and engaged him. Every movement announced absolute control. ‘Tell me.’ A low kick crippled Stronos’ second knee joint and he slid down the wall to the ground.

With a whine of servos, Barras lowered himself to one knee. Stronos threw a punch. Barras batted it contemptuously aside on the outside edge of his vambrace and headbutted Stronos in the eye, driving the flat rim of his bionic deeper into the flesh and squeezing out more clotted ooze. They locked arms, scraping, straining. Barras had the position, but Stronos’ heavier build and machine-augmented power were still too great to be overcome.

‘One outlier does not… disprove… the rule.’

The outside of Barras’ boot ploughed through the already weakened servos of Stronos’ right elbow. The arm caved in, and the sudden shift in weight dragged Stronos’ left shoulder forwards and his face into the vambrace that Barras smashed into it. The back of his head recoiled into the wall, and brought another torrent of bone-dry red dust over his head.

He looked up groggily with his flesh eye, while his bionic glitched as if haywired.

‘Two failures in one day,’ said Barras, the frozen articulations in his gauntlet cracking as they re-clenched into a fist. ‘You must be overcome with shame.’

‘That is enough, Aspirant Barras.’

Magos Instructor Yuriel Phi stood on the other side of the table, robed and hooded, her cable-dreadlocks spilling down her chest. She was an elfin figure up close, barely a hundred and fifty centimetres in height, flat-chested, slender, her hands silvery and small, but there was a force to her that ensured that Thecian, Sigart and Baraquiel had all withdrawn a respectful distance.

‘Honour is satisfied,’ she said.

‘Is it?’ Barras turned to Stronos.

Stronos managed a nod. What was honour anyway?

‘You are the superior fighter,’ he said, flatly.

Barras snorted, as if saying nothing was better than stating the obvious, but offered a hand and helped drag the Iron Hand’s spark-fizzling bulk to his feet. ‘A good fight, though. I would like to fight you again some day, if you are willing.’

As if there was any logic to engaging a demonstrably superior opponent. If only he had taken the effort to know his fellow aspirants before agreeing to fight one of them.

There was something to what Lydriik had tried to teach him after all.

‘Of course he’s willing!’ shouted Baraquiel, thumping on the table.

‘Good.’ Barras’ expression settled into its usual etched frown. With little else to work from, Stronos had no option but to assume that the Knight of Dorn meant what he said.

‘I really thought Stronos might beat him,’ said Thecian, wistfully.

‘We have thirty years of this yet,’ said Sigart. ‘One of us is bound to best him eventually.’ Thecian offered the Black Templar a raised fist in salute, which Baraquiel caught, clasped between both of his hands, and then drew the Exsanguinator into a back-thumping embrace.

Such brotherhood. Where did it come from, Stronos wondered? From which genhanced organ did it manifest, and what mis-code of Ferrus’ seed meant that Stronos could merely observe and feel nothing?

‘Come,’ said Magos Phi, turning away. ‘It is time.’ Thecian and the others immediately bowed their heads and made to fall in behind her for the procession to evening prayers. She glanced back over her shoulder, eye twinkling between red and blue from behind a fall of dark cabling. ‘Just Kardan.’

CHAPTER SIX

‘It is difficult to keep secrets in the Eye.’

– Logi-Legatus Nicco Palpus

I

The file descriptors were starting to blur together.

Lydriik let the data-slate slip through his fingers, collapsing the untidy pile that had been building on the scrivener’s bench, and pinched his eyes, ignoring the nervous shushing that echoed from the direction of the prime archivist’s podium. He tilted his head back, blinking quickly, feeling his eyes relax as his focus fled into the ceiling’s blackwork frescos. He could hear the wind groaning against the domed roof, and for some reason that was soothing too. With a sigh of quiet capitulation, he slumped back over the bench, picked up the slate, elbows spread, and forced himself to read the opening line.

It was a compilation of sensorum logs, drawn from the Medusa IV perimeter fleets, orbital compliance vessels and the transorbital control hub situated within the old Telesterax ring between time stamps 101412.M41 and 102412.M41. Incoming and outgoing ships were filed by name, numeric registry, manifest and lengthy ordinate strings related to auspex and augur reads taken by the recording ship at the time. With a groan, he sank fully to the bench. Slates shifted under his forehead, little plastek grubs wriggling away from their hateful mother.

Medusa’s population was a continuously fluctuating estimate, varying between five hundred thousand and two million depending on the severity of the climate and internecine strife. There were ghetto districts of Imperial cities that held more souls than Medusa.

Even given the significant pull-factor of the Iron Hands war fleets and the Basilikon Astra, the amount of void-traffic it received daily was staggering.

Lydriik was starting to feel he had not protested this assignment quite strenuously enough.

Trying to find even the official destination point of the million-or-so technological artefacts evacuated from Thennos post-compliance was like trying to track the path of a thought through his own head. Xenos artefacts accrued over eight thousand years of Martian rule had been shipped off-world over a matter of days, all at the exact same time that tens of thousands of skitarii legionaries from the Hadd forge world in the Golgenna Reach were arriving to secure the compliance. He had successfully tracked a consignment of eldar grav-tank parts across three segmenta to Ryza, and even located the import dockets confirming their receipt. He had followed chains of Iron Hands and merchant vessels, tracing their cargo handover to handover to their destinations on dozens of disparate worlds.

Locating the destination port or ports for the Dawnbreak Technology should have been a simple enough task. There could not have been more than a hundred worlds in the entire Imperium with Inquisitorial license to handle and trade in xenos technologies. It was the sheer volume of shipping, the near-impenetrable machine argot of the Sthenelic merchant clans, and the deliberately obtuse Mechanicus logister codes that made it feel like looking for orbiting debris around a distant sun.

He rubbed his eyes and picked up another slate.

He had started in the Librarius archives, within the confines of the Astropathica sanctuary in the outer fortifications of the Telesterax. He was respected there, and the Librarians of the Iron Hands had always been a breed apart. Many originated from foreign worlds, as Lydriik himself did, bartered from the Black Ships as they passed through the Iron Hands’ loose diaspora of client conquests. Whether it was for that reason or the organic basis of their mental powers, they tended to be uncommonly attached to their flesh.

From there, he had made the perilous descent by Storm Eagle, piercing Medusa’s seething storm systems to set down before the fortress of ironglass that served as the Chaplaincy’s basilica upon the great mesa of Karaashi. With gifts and tokens of future aid from the Lord Librarian Antal Haraar, the Father of Iron had grudgingly permitted Lydriik supervised access to his vaults.

They had held nothing of relevance.

He had bartered the Storm Eagle for one of the Iron Chaplains’ Rhinos, the attrition rates suffered by Medusan aeronautica being equivalent to that experienced by combat squadrons, and with it criss-crossed half of Medusa’s primary landmass. He had gone as supplicant to the Land Behemoths of the Morlaag, Sorrgol, Haarmek and Kaargul clans, traded favours owing to the Chapter Librarius and to Inquisitor Yazir, all for a few days with their data troves. There was always a slim chance that some clan’s ship had sniffed something untoward.

But no.

He sighed.

The Council archives had always been his best chance at finding where the Dawnbreak Technology had been moved. He had known that since Harsid had released him from his tithe of service, but it was one he had preferred to avoid while other avenues remained open.

He glanced up from his stack of slates and scanned the archive chamber warily.

The human servants of the Eye of Medusa moved quietly through the great data stacks. With diligence, they filed, ordered, polished, catalogued, copied, restored, loaded carts with requested collections and wheeled them for the equerry-servitors of Iron Fathers and High Priests to convey. Even when they passed out of view behind a stack or into a study annexe, Lydriik could see them, tiny soul-fires guttering in sconces of pale flesh and plain cloth. He knew each of their names, what they were doing, where they were going, who they most loved, what they most feared.

The human soul, it transpired, was less complicated than Adeptus Mechanicus files of lading, even when looked on in passing.

It was one such ember-glow, rather than the scuff of sandal leather on the diorite flags, that forewarned Lydriik of the archivist coming to unload a fresh stack of documents. With a sigh, Lydriik cleared a space and gestured for the man to set them down. With the barest tremor to betray his mortal terror the archivist hurriedly, but with tremendous care, transferred the pyramid of crisp, newly scribed parchment scrolls from cart to bench. He bowed again, and fled, the wheels of his trolley clattering, his spirit spasming with the purples and reds of a hunted mammal. Lydriik smiled indulgently as he unrolled the uppermost scroll. Space Marines were infrequent visitors to the archives. Few Iron Hands even knew they existed. And no man of sound mind could ever be comfortable in the presence of an Alpha-grade psyker.

With a deep breath, he leant in and started reading.

He had been scanning the documents for about forty-five minutes when a crawling sensation took up in the middle of his forehead. As if he were observed. He glanced up over the curling parchment, and almost crushed it in his hand.

The Helfather stood on the other side of the bench, as still as a three-metre-high engraving of a Terminator-armoured ancient. The age-dulled plate was eerily silent, bereft of the usual sounds of power generation and life support that usually accompanied so heavily augmented a warrior. A human soul did not so much as flicker. He was dark to Lydriik’s mind, it was like looking at a wall. His lenses too were unlit, the same scuffed black as the helmet, but Lydriik could feel the weight of something’s attention on his brow.

Lydriik lowered the scroll lest he damage it, and with a stiff hand smoothed it flat.

What he wanted to do was push himself as far from the Helfather as he could make it in one movement, but one did not rise to become Prime Librarian of Clan Borrgos without supreme self-control.

‘Please,’ said Nicco Palpus. ‘Do not allow me to disturb you, Epistolary.’

The gaunt frame of Nicco Palpus, the Paramount Voice of Mars, emerged from behind the Helfather’s stolid bulk. His robes were rich with the sigil-wiring of high office, but his face, for a priest of his status, was remarkably human. Lydriik peered through the soft metallic glaze of his eyes to the old soul within. It was a curious mosaic of pieces, as if the logi-legatus had been assembled in stages over many hundreds of years. Lydriik brushed the priest’s surface thoughts, skimming an endlessly looping mantra of ones and zeros. Drawing his mind back, he became aware of the priest’s eyes quietly clicking, his milquetoast expression melting and reshaping into something other. Seeing his own studied resolve, hints of tension in the muscles about the eyes, reflected back at him, Lydriik supressed a shiver.

When Harsid and Yazir had dispatched him on this assignment, he had insisted that thirty minutes alone with Nicco Palpus was all he needed to see the mission done.

Thirty seconds in, Lydriik was not sure who was reading who.

‘I did not realise I had announced my presence,’ he said, keeping his voice low, while Nicco Palpus summoned a stool and sat, drawing his robes into his lap. Lydriik’s eyes flicked to the Helfather, still standing, sightlessly watching.

It had not moved.

‘Lips open. Molecules bump together. Word travels. Such is the workings of the Omnissiah’s universe. It is difficult to keep secrets in the Eye.’ Palpus’ smile shimmered, like moonlight behind a cloud. ‘But not impossible.’

‘Perhaps you can help me unravel one,’ said Lydriik.

‘Undoubtedly.’

‘Secrets and lies are anathema to the Omnissiah, after all.’

The logi-legatus’ smile broadened. ‘A commonly misused tenet, for nothing known to one is unknown to the Omnissiah. Thus, there are no secrets. Never challenge me to a debate on theism, Epistolary.’

Lydriik dipped his head in concession of the point.

‘You are seeking the Thennosian archeotech. I believe Kristos still refers to it as the Dawnbreak Technology.’ Palpus’ smile evaporated. ‘Why?’

‘I think you know why.’

‘Your mistress has some authority, but this is Medusa, the Iron Council are seldom impressed by agents they can break with one hand, regardless of the symbol they wear.’

Lydriik frowned, picking up on a strained unease within the Voice of Mars’ thoughts. He leaned forwards, highly aware of the Helfather looming over the bench, determining to lean on that thought and see what pressure it could bear. ‘Yazir will not stop searching, you know that. This is Kristos’ obsession. It would be easier for you to cooperate, in the long run.’

‘Perhaps.’ Palpus’ expression reformed into one of smiling munificence. ‘Tell me what you already have, and maybe I can fill in the blanks for you. As a gesture of my cooperation.’

Lydriik licked his lips.

‘How fares Jorgirr Shidd?’ Palpus asked, amiably.

Lydriik found himself recalling the red jump-suited tech-crew that had received his Storm Eagle at the Chaplaincy basilica, the data-savant that had roused his terminal and even the servitor that had escorted him to the deeper vaults. He shook his head. Trying to speculate on what the Voice of Mars knew and from where was pointless. Better to simply assume that he knew everything, and that anyone wearing the Cog Mechanicus was potentially listening – whether their minds were aware of it or not.

‘Still not dead,’ he answered, carefully.

Palpus nodded as though this were news. ‘He seldom visits Meduson, even for the Iron Moon.’

‘The Father of Iron has little business to conduct in the Eye. The Chaplaincy has no voice on the Iron Council.’

‘Very true,’ Palpus conceded. ‘As it is with the Librarius.’

Lydriik bit back a response of the flesh. ‘Quite.’

‘And what information does Shidd hold within the Ice Pinnacle?’ Palpus’ attention strayed towards the documents spread out between them. ‘And the recordists of the Morlaag, Sorrgol, Haarmek and Kaargul clans, what knowledge were they able to provide?’ His fingers alighted on a slate and began to turn it towards him. With transhuman reflexes and a shadow of the Emperor’s gift for premonition, Lydriik’s hand shot out, swallowing the priest’s and pinning it to the bench. Their eyes met. Palpus’ flicked towards the Helfather.

It still had not moved.

Lydriik let go.

The logi-legatus left his hand where it lay for a moment, watching Lydriik, then picked up the slate and sat back. He did not bother to look at it.

‘Don’t play games,’ Lydriik hissed. ‘You know what I’m looking for.’

‘I know. And as Mars’ voice and custodian of the Iron Hands, I choose to deny you.’ He looked Lydriik up and down and sneered. ‘Like children, you have no concept of danger.’

Lydriik rose angrily from his chair. ‘We are Adeptus Astartes.’

‘Your infantile emotional range is housed in the bodies of gods. You are weapons built to do violence in the Emperor’s name. What free will you possess is an illusion, and be thankful, for the Iron Tenth would have driven itself to annihilation millennia ago if not for the gracious hand of Mars.’

Lydriik was speechless. He gaped as Nicco Palpus stood and smoothed out his robes.

‘The data will all be here somewhere,’ he said. ‘Does the Scriptorum of Iron not warn us against deleting anything, lest it later be revealed to have value?’

A smirk crossed Palpus’ features, swiftly masked. ‘Indeed it does.’ He nodded farewell, making to leave, only to then turn back as though remembering something he had meant to say. ‘I understand that Iron Captain Raan has just made planetfall on Manga Unine.’

Lydriik nodded. He had heard the news. Manga Unine was a sprawling campaign, decades old, and a war of attrition against an endemic xeno species called the Calx that several million Imperial Guardsmen and eleven Chapters of Adeptus Astartes had not been able to finish.

It also just happened to be on the other side of the galaxy.

‘The Calculus is the Calculus,’ said Palpus, apparently reading Lydriik’s thoughts more precisely than the Librarian could the priest’s. ‘With the Raukaan and Garrsak clans already dispatched elsewhere, and Clan Vurgaan taking their turn of garrison duty here on Medusa, the Borrgos were the only clan in fit state to respond to the call.’

‘A call we have been ignoring for twenty years,’ said Lydriik.

‘The iron captain may well require the presence of his Prime Librarian. I would not be surprised if you were to be recalled to front-line duties soon. Congratulations, Epistolary.’ He dipped his head again and turned to leave. ‘We should all do what we are made to do.’

Lydriik glanced up at the Helfather.

‘Do you ever wonder why they never talk?’ he murmured, as much to himself as to the logi-legatus.

Palpus looked over his shoulder. ‘Perhaps they simply never talk to you.’

CHAPTER SEVEN

‘Quantitatively my favourite xenos breed.’

– Iron Captain Draevark

I

Rauth could make out the void fight at the system’s limits with the naked eye. The crackle of ship deaths and ordnance detonations lit up a narrow window of the stellar horizon. An informed observer could glean a lot from those explosions. The brilliant white burn of iridium-tipped torpedoes. The more silver-white of cobalt, from the Mort XIII forge world, most likely, its crust long depleted of the harder, more valuable, transition element. That would be the Beacon of Terra. Its twisting path through the sacred sites of Cyclopoea brought the strike cruiser regularly into orbit with that world. Void shield discharge presented an intermittent, electrical flicker. Brown-shifted blooms of ferric iron and unrefined promethium marked the demise of alien ships. The bulk of the combined Imperial fleets was holding anchorage over Fabris Callivant. Their formation was solid, the upper orbital bands bristling with battleship broadsides and the fixed aegis of defensive platforms. But the Hospitallers were not built for holding territory; they were void warriors, reavers and crusaders, line-breakers, and they were determined to reap an early tally from the aliens’ forerunners.

They came in dribs and drabs.

Commanders better than Rauth would struggle to deploy a large number of ships through the warp with anything approaching coordination, but the lack of forethought on display was typical of the xenos breed.

Despite the efforts of the Hospitallers and Warfleet Obscurus, the aliens held swathes of territory, spread across the boundaries of three sectors. Fabris Callivant’s first line of defence against such incursions had always been isolation. It had no resources of any kind. It was a stepping stone to nowhere. Easier pickings and choicer targets lay well within reach of their territorial sprawl, and the actions of the Golden Ratio and her escort flotilla had always been calibrated to divert such threats onto the defences of such targets of opportunity. And yet every chance occurrence, fifty-fifty fall, freak convergence, oddity in the warp and act of God had come together to lead the xenos step by step to the gates of Fabris Callivant.

The light delay between Fabris Callivant and the heliopause was a little under seventeen hours.

Given the volume of alien shipping translating in-system, it was almost certain that the Hospitallers were already in retreat, the aliens securing their bridgehead and despatching spoiling raids of their own.

How long before the first salvos were fired over Fabris Callivant?

A day? Two?

He watched through a plate of armourglass thirty centimetres thick. A reflection looked back at him through the window. A bulbous helm, tall and narrow, fluted like an ivory drinking vessel with aquamarines gracing its elongated neck, a tinted visor, blacker than the void outside. A shiver passed through him as the reflection morphed. The blank helmet became a cold face, weathered hard and pale with scars. It was his face. But with a milky white augmetic staring blindly from where his eye should be.

No. That was Khrysaar.

A sound like snapped fingers rang suddenly in his ears, and he blinked, staring now through his own reflection at a battle that seemed altogether further away than it had been moments before. Disquiet pressed him from all sides. He touched his hand to the glass, as if to fix himself on a point in space. Iron Hands’ body temperature was naturally low, and the interiors of the Lady Grey were marginally warmer than he was. The heat on his palm made him shiver, the hand touching his in reflection momentarily long-fingered and yellow-gloved.

Rauth had no memory of how he had come here.

II

‘Rauth.’ The voice echoed around his consciousness. ‘Rauth.’ Fingers snapped again, this time right by his ear. He turned, unease curdling in his stomach, to find Cullas Mohr frowning at him, the Apothecary’s face right in his. He jerked sharply away.

Trust an Apothecary to be involved somehow. ‘What are you doing?’

‘You faded on me,’ said Cullas, shifting his head in an attempt to catch a look at Rauth’s eyes. ‘Does this happen often?’

When did I leave the planet? ‘No.’

The Apothecary’s frown deepened. Grim preoccupation was its default repose. ‘We should continue your debrief in the medicae ward. I will arrange for samples of blood and brain lymph to be drawn–’

‘No. No more samples.’

‘The inquisitor will insist.’

‘Then call her down here. Wherever she is.’

Cullas sighed, his breath as harsh as the north wind on the Ooranus crags, and turned to peer through the armourglass viewing panel. His armour was the matt-black of the Deathwatch, his right pauldron bearing the red on blue heraldry of the Brazen Claws. His left hand had been retooled with a narthecium augmetic. A patterned shimmer obscured his eyes, not true bionics, but rather a nanomolecular film overlay that sat across the organic originals. He looked like an Iron Hand, but he was no Iron Hand. He smiled occasionally, laughed at Ymir’s stories and wore his exasperation with Rauth plainly on his sleeve.

This, presumably, was the product of attempting to work Ferrus Manus’ seed without the cold-furnace of Medusa to smelt it. Hard, but filled with impurity. Brittle.

‘Shall we continue then?’ said Mohr.

Rauth grunted. He turned back to the glass. A reflection of the Apothecary loomed large over the shoulder of his. The skin of his nape crawled. What Dumaar and his subordinates left of my brain I’d prefer to keep away from your narthecium, if it’s all the same to you. ‘If we must.’

‘Have you noticed any alterations in sensation? Brightening of colours, tinnitus, synaesthesia? Anything of that kind?’

Rauth peered through his reflection. ‘No.’

‘And mentally. Any disturbing or recurring dreams?’

‘No.’

‘Anything you’d describe as unsettled emotions? Anger, depression, paranoia?’

Funny you should ask. ‘No.’

Cullas shrugged. His massive shoulder armour responded with a grind of servos. ‘You are the only surviving subject to have been in proximity to the Dawnbreak Technologies.’ And Khrysaar. ‘Except, perhaps, Iron Father Kristos. That we know of. The inquisitor is justified in wishing to know its effects on you.’

She wants to know if I need to be destroyed along with the population of Thennos.

‘Even if you were not affected, that is valuable information. So answer the question. Without the belligerence.’

I’ve been trained to survive at any cost. I have murdered brothers, betrayed others, lived through hell and been remade stronger. Do you think my conscience will even feel the weight if I lie to you? ‘No unsettled emotions.’

‘Are you certain?’ Cullas’ eyebrow pushed up into the deep worry lines of his brow.

‘If you don’t trust my answers then why ask the questions?’

‘Perhaps it is the answer you choose to give that interests me most.’

Frowning, Rauth turned from the glass.

There was something about the Lady Grey’s port observation chamber today that left him dizzy. As if the floor were turning, but the walls and ceiling weren’t. Only his genhanced physiology, impervious to motion sickness, and a vomit reflex that had been completely redesigned, let him ride it without betraying his unease.

The Lady Grey’s official launch date was 009102.M41, a near-light cargo schooner constructed as grace-and-favour for one of the horrendously wealthy trade magnates that controlled the shipping lanes under the Hospitallers’ sphere of influence. In the last five and a half decades – still on Administratum lists as being under the licence of Epicurate Hypurr Maltozia XCIII, fifty-five years deceased – she had been up-armed and retrofitted. Grown powerful off the semi-legitimate trade in xenos weaponry, she could match guns with an Imperial light cruiser if she needed to. But there were few circumstances in which she should, given that there was no standard class of Imperial warship even remotely as fast. At less than three hundred metres in length, she was dense on power and light on space. The wainscoting of the observation chamber walls, in style and aroma a recreation of the gentlemen’s lounges of ancient Terra, pressed uncomfortably close.

‘Look me in the eye, neophyte.’ The authority in the Brazen Claw’s voice was irresistible, and Rauth threw the Apothecary a sharp look. Cullas’ eyes narrowed, as if pinching his in place. ‘Have you noticed any change in your condition at all?’

‘No.’

Cullas held Rauth a moment longer, then released him with a slow dip of the head. ‘I shall forward the inquisitor my appraisal.’ With that he turned and strode towards the two teardrop-shaped wooden tables.

The growls of Ymir and Harsid came from the square of floor beyond it. The two Space Marines wore training fatigues, their torsos bare. Muscles rolled like cables, plates of transhuman brawn swelling across their broad backs as they wrestled. Intent on their locks and throws, neither one of them seemed to have noticed Cullas, or Rauth.

Rubbing his head under the palm of his hand, Rauth turned to the nearer of the two tables.

A row of reinforced chairs faced towards the armourglass. Laana Valorrn sat in one of them, stiffly upright, her attention split between the starry vista and some imagined smirch on the table’s lacquering. She buffed idly at the surface with a black kerchief, the sort of low-tech face protection that every Medusan carried as a last resort.

Rauth grunted, arms crossed for a moment, deciding whether he would rather be alone, then moved to join her.

‘What?’ she asked, looking up through stiletto-thin lashes, still polishing.

How long have I been back? How did we get here? How do I even ask these sorts of questions without making myself servitor-fodder?

‘Where is Khrysaar?’

‘Fort Callivant,’ she said. ‘Yazir was able to find the location you extracted from the augmentician. The emblem you described was the key. The Frateris Aequalis. Yazir has been aware of them for some time and they do not appear to have taken any great effort to conceal their activities.’

‘House Callivant is decrepit and weak.’ Rauth shrugged.

‘I had Khrysaar warehoused with the cyber-ghouls for the next tournament. The adept you saw in the augmentician’s remembrance is not just another official with a taste for blood sports. He is with the Aequalis cult.’ She drew back her kerchief and frowned at the pristine surface. ‘We should have suspected.’

‘Are they connected to the Dawnbreak Technology somehow?’ Rauth asked.

Laana stopped working at the tabletop and looked up. She said nothing.

You should be polishing my bionics, not deciding what I can and cannot know. Rauth glanced up as Ymir slammed onto his back, his arm twisted back in a lock, Harsid on top of him.

‘You don’t like me, do you?’ he said to her.

‘Gods disappoint.’

Rauth was uncertain whether to laugh aloud or just snap the human’s neck with his fingers.

Belief in the divinity of the primarch, and of his second coming, was as old as the Codex Astartes. Bettered only by its theological offshoot – that Ferrus had not died at all, or that he had given his life away not out of impetuosity but as a lesson to his children. It pervaded amongst the nervous and the weak, the older warriors of the more barbaric clans, the Vurgaan in particular, and, he supposed, the mortals.

But nothing felt quite certain to him at that moment, and even the ludicrous he found difficult to dismiss out of hand.

I wish Khrysaar were here. He felt the need to talk to his brother, though he was unsure why. Nothing specific, only that everything would click back into some kind of natural logic if his brother were there with him. What else am I still doing here, conversing with a woman I loathe on a topic I think risible, and for whom all feelings of disgust are as mutual as they are confused? She was a part of something familiar.

A world I despise, but you take solace where you find it.

Rauth turned his back without saying anything further. He looked through the armourglass, that narrow window of fire-flicker on the stellar horizon. ‘If we can’t find the Dawnbreak Technology in time, will we help defend this world? Or will we let the xenotech burn with the planet and call it a task well done?’

He could feel Laana’s eyes on his back. ‘It depends on whether Yazir deems the risks worth the costs. You should be familiar with that calculus, Iron Hand.’

Rauth nodded. His mind was starting to spin again. Without another face to focus on, it was almost as if he were talking to himself.

‘Where is Yazir?’ he asked

‘Look at that,’ muttered Ymir, before Laana could answer, palming the Death Spectre off with a playful growl and padding towards the observation plate. His grey pony tail looped over his shoulder and fell down his immense, fur-matted chest. Rauth could see the tremors of his reserve heart beating under his lined, tattooed flesh.

The sight of the burly Wolf’s untampered physique made Rauth squirm in his own skin, at once impressed by such magnificent physicality and repelled by its unaugmented form.

‘Another ship coming in.’ Ymir pressed his palms to the armourglass and sniffed at it. ‘Imperial. A large one.’

Harsid had picked up a towel and was mopping his hairless brow. He joined the Wolf at the observation plate. His red eyes peered into the dark, though it was clear he did not see nearly as keenly as Ymir.

‘I will inform the inquisitor,’ he said.

III

Draevark ignored the alarms. Unmanned screens flashed up with enemy contacts. Proximity alerts blared from the ship-wide augmitter grids. Updates and notifications from allied vessels chirped and screamed, faster than the Alloyed’s skeleton crew could respond.

Through the main forward oculus, a flattened hexagon of steel girders haloed with heavy cables and a brooding Cog Mechanicus, he watched an ork kroozer patterned in blue-and-white jags come apart under fire. Its shields burned out. The Brutus unloaded another punishing broadside into its aft section. The escorts Strength Eternum and Mount Volpurrn battled with half a dozen similarly sized ork ships, but could not get close to the strike cruiser. Fightas spat fire and wound the capital ships in chemical tails. Hatches in the Brutus’ stomach opened up and disgorged swarms of servitor-piloted Stormtalon gunships, their contrails knotting with the dirtier tails of the orks. Shield discharge strobed.

If Draevark had turned one hundred and eighty degrees to face the bulkhead behind him then he would still have been able to form a decent understanding of what was happening from the flashes on the metal.

The ork kroozer continued to break up, overcoming its own internal gravity as the Brutus unloaded another salvo, annihilating what was left.

Through the expanding nebula of atomised atmosphere and scrap metal, another half a dozen lighter ork destroyers came into view. They surrounded a single dagger of sharp, serrated white.

A Space Marine strike cruiser.

‘The Final Duty,’ announced one of the mortal crew-slaves. Despite the alarms, peals, bleeps and demands for the small bridge crew’s attention, there was no panic. The menial’s big hands, one a crude two-pronged augmetic attachment, played over the tacticae runebank. ‘More transponder signatures coming in. Nine warships of the Hospitallers Chapter. Under the flag of the battle-barge Shield of the God-Emperor.’

‘Input the data,’ ordered Draevark.

‘Thirty-two ork ships confirmed,’ called another man.

The ork ships were arriving and being destroyed faster than the Alloyed could track, but his crew knew better than admit to fallibility.

‘Orks,’ Draevark spoke after a moment’s analysis, his ability to parse the Alloyed’s information streams surpassing that of his entire bridge crew by several orders of magnitude. ‘Quantitatively my favourite xenos breed. They always behave as you would expect.’ Spirit-guided weaponry lit up the main visual feed, shredding a squadron of overpowered ork bommers as they pulled out of an attack run. Torpedoes looped under a slowly rolling frigate, burned across the ventral beam of a kroozer’s shields. ‘There is nothing like a palette cleanser after eighteen sidereal months hounding eldar.’

‘Lord.’ Another man (no, a woman – gender differentiation among mortals continued to baffle him) turned to him between tasks. ‘Auto-responders detect hull breaches on decks two and ten. Boarders.’

‘I am aware,’ Draevark replied. He drove a thought-pulse through the clan interlink, temporarily overriding the higher thought functions of Sergeants Artex and Coloddin. ‘Second and ninth sergeants already moving to deny,’ he added.

He turned his attention towards the Alloyed.

The aged warship had her own overlapping thought-algorithms and instincts when it came to battle. She was more than capable of fighting alone if she had to. The humans and servitors aboard were maintained for the performance of manual tasks. They fed her engines, cleared jams in the macrocannons’ autoloaders, pushed buttons, exchanged code wafers and reminded Draevark of his superiority over the rest of mankind. As of the present moment, the Alloyed was coming abeam of an ork kroozer half again her tonnage, just a few hundred kilometres of angry space between their blistering shield bubbles. Draevark felt the mechanical fury of her spirit, and spread it evenly amongst his brothers through the clan interlink. Claves Artex and Coloddin would be better served by a bitter taste of emotion than he.

With a nudge of thought, Draevark urged her to draw aport of the Brutus, using her sister ship for cover to divert reserve strength to port void banks.

As she began to move, a colossal detonation brighted out the main oculus. The crew grunted and shielded their eyes. Draevark watched, unmoving, auto-apertures and polarity filters in his twin optics mitigating the input spike.

The kroozer was gone. A fireball in its place. Flaming tendrils shot out from it, like some tormented kraken of the deep void. A massive wedge of black partially eclipsed it, the occasional glint of silver as the fires choked and shrank back.

‘The Omnipotence,’ announced another nameless serf. ‘The Shield of the God-Emperor is hailing them.’

Draevark turned his vulturine helm, and the crewman flinched before the sudden anger that surged through his binoptics.

‘Splice me into that frequency.’

‘But… lord?’

‘Kristos has Clan Garrsak’s allegiance. He does not yet command its vassalage. You will do as Iron Captain Draevark commands you, mortal.’

‘Aye, lord. It is just… it is the Raukaan Clan ironbarque. Its spirit is more ancient than the Alloyed and more powerful.’

‘Is that an admission of inadequacy?’

‘No, lord!’ the mortal cried, bolt upright like a prey beast in a headlight, then spun away to attack his runebank’s ciphers without the need for further command.

Draevark flexed his lightning claws. Without power, each talon moved only with tremendous difficulty. As if he had a hundred kilos of adamantite cutting edge weighted to each knuckle. The fuel to the underslung flamers in their wrist cradles sloshed as they moved. Void war was very fine, but he preferred the straightforward immediacy of melee. Imposing his will over chaos and enforcing order. Nevertheless, he could see the mighty rivets of the Brutus’ hull plating dragging past the ancillary starboard oculi, a string of steel-framed sub-screens stitching together a live-feed from the strike cruiser’s flank. Their combined firepower was chewing through the disordered flotsam of ork shipping. The Strength Eternum and the Mount Volpurrn, as well as the torpedo destroyer Corpus Mechanicus, finally found the room to wedge in alongside their capital ships.

The coordination of the five vessels’ firepower was imperious, a testament to the Iron Hands’ mastery of war.

‘Confirm that target matrix codephrases are being cycled every two point five seconds,’ said Draevark.

‘Confirmed.’

In allowing the Omnipotence to wrest control of the Alloyed’s weaponry at Pariah-LXXVI, Kristos had crossed a line. Draevark had not spoken of the matter with Tartrak, the senior officer aboard the Borrgos Clan vessel, but he had no doubt that he felt the same. And now Kristos had demanded Haas join his harem of Apothecaries aboard the Omnipotence. Draevark glowered into space. Kristos was an Iron Father, a messiah to some, but even he had limits.

The Iron Hands would suffer no absolute monarch. Not after Isstvan.

‘Lord!’ came the stressed cry of the slave at communications. ‘I have a signal.’

Draevark basked in the pitiable glow of satisfaction. There was nothing like the prospect of bio-recycling or servitude perpetualis to encourage a mortal crew to find solutions to problems.

‘Do not make me ask for it,’ he growled.

The crewman practically fought with his own hands to get the intercept on speakers. The signal was looped and distorted, the binaric chirp of the Alloyed’s vox-thief algorithms chattering through its sub-frequencies. Draevark tuned his audial devices to filter it out. It was Kristos. And the sibilant voice of an Adeptus Astartes battle-brother he did not recognise.

‘Welcome to the place of judgement, Omnipotence. Does your fleet require escort to Fabris Callivant?’

‘For my vessel only. My fleet can remain with yours.’

‘Very good.’

‘Request authorisations to come aboard. We have much to discuss…’

The signal terminated. A stilted whine ran through the augmitter grid. Draevark listened to it, his choler blackening.

‘My lord. The Omnipotence is trying to raise us. Shall I put her through?’

‘No,’ Draevark answered after a moment. ‘Inform the Iron Father that Clave Jalenghaal is already on its way to his ship.’

CHAPTER EIGHT

‘That is why the position of the Voice of Mars exists…’

– Exogenitor Louard Oelur

I

The strings of a harpsiclave filled the cramped taberna with a pulsed vibrato. Rain muttered against the low roof, and fled down the faces of the muted grotesques that leered from the windows in stained glass. Melitan looked down, her hands shaped as if around the tubular neck of her instrument, but it was not her that was playing. She looked up, confused, through the cloud of lho smoke to the tiny corner stage where a woman in grimy red robes sat on a stool, her legs straddling the aluminium frame of the harpsiclave. The clavist’s head was bald, ringed by rad-scarring, her skin olive dark; her thighs, chest, face and in-folded hands were lit a shadowy blue by the plasmic resonance of plucked strings. The light occluded the woman’s face, as if it were too thick and heavy to make it across the room, and yet Melitan had the sickening certainty that it was her playing after all.

‘Bethania Vale,’ whispered Callun Darvo, leaning across from his chair at the table beside hers. His fingers drummed a nervous rat-a-tat on his table as he looked to the stage. His face too was difficult to make out, even though his hood was up. ‘I heard she was better.’

The clavist shifted chord to a high frequency and Melitan drew her hand to her ear in sudden pain. The anonymous crowd of off-shift menials and labourers filling the taberna responded with approval.

‘I don’t know this piece,’ she shouted over the aggressively rising cadence.

‘It is called The Sapphire King.’ Tubriik Ares sat at her other side, as poorly defined as a nightmare. ‘It is not my favourite.’

‘There is something about it though,’ Callun argued.

‘It is always better the first time,’ said Ares.

The pitch shifted upwards once again, and Melitan’s face sank to the table, both hands clamped to the sides of her head.

‘Bravo,’ Callun cheered, and started clapping.

There was a metallic clunk as something heavy hit the stage, then another, and another, faster and heavier, rain hammering on a tin roof. Melitan lifted her face from the tabletop to see the clavist disappearing behind a rising pile of rejected augmetics. At the foot of the stage, a grunt mechanic rose from his seat, tears of joy running down his acid-scarred face as he sank fingers into his eye socket and gouged out a bionic eye. Blood streamed from the gaping socket in place of tears as he tossed the bloody metal into the heap, then thumped his bloody hands together in rapturous applause.

The clavist rose from her stool and took a bow, but the music continued without her, louder, the plasma strings continuing to resonate. Melitan whimpered.

It was not Bethania Vale anymore.

It was Nicco Palpus.

Pain drilled into her head through both ears and she screamed, clawing at the table, her fingernails as frictionless as lho smoke, choking on her own tongue, gasping, her brutal aneurysm going utterly unremarked next to the shriek of a harpsiclave and the baying of a crowd…

II

Melitan woke up screaming, the sound of a strummed harpsiclave pulsing through her thoughts. The dormitory cell was dark. It smelled of rust and her sweat. She half fell out of her cot, legs tangled in the bedding gauze, and stumbled towards the night-glow square of the control panel. Her legs collapsed from under her after two steps. Sobbing in pain, she buried her head in her hands as though she could bury the migraine. Reaching out with a clammy hand she found the wall, and walked it up the metal, using it for leverage to draw herself to an upright kneel. She puked against the wall and collapsed again.

III

The throbbing chord became an insistent buzz. It was not in her head anymore, but coming rather from three or four metres away in the dark. She grunted and spat bits of sick from her mouth. The taste of it coated her tongue. Her gorge rose again, but she swallowed it, grimacing, and struggled weakly to her feet. Her hand slapped along the wall until she found the knobs and switches of the control panel. The lights came on in a flood, clinical and bright, and she felt tears burn her eyes, whimpering at the sudden flurry of misfires in her brain. Covering her eyes, she ground the knuckles of both hands into her forehead.

‘Ave Omnissiah. What have you done to me?’

The thought of Palpus’ meme-proxy reworking her neural architecture while she slept threatened a second wave of tears.

What would be left when it was finished? Would it still be Melitan Yolanis that returned to present her findings to the Voice of Mars? A fragment of dream imagery jittered just out of reach, and she shuddered as she felt its escape.

Or would it be Bethania Vale?

The buzzer sounded again. Five seconds exactly after the last. She looked up. The door chime. Wiping tears from her face and managing to smear her cheek with sick from her sleeve into the bargain she hurried to the door. She deactivated the lock switch and the door slid away.

The foetal cherub hovered in the corridor, loose sparks drizzling from its arcane propulsors, the burned odour of warped gravity. Its single distended eye, the blue data gem forced into its tiny mummified socket, stared through her as if the state of her cell were abhorrent to it.

She covered her mouth with her hand and made a concerted effort not to throw up.

<You are three minutes and sixteen seconds overdue, Magos Vale.>

Its use of that name, in a binaric form she was certain she should not be able to decode, made her eyes water. Nicco Palpus hadn’t warned her about any of this. Why hadn’t he warned her? She thought of Callun. He had been in her dream, she was sure, which he probably would have enjoyed had he been alive to hear about it. The memory of him left her feeling oddly despondent. She would have given anything for the chance to wake in the communal dorm on the Broken Hand and find that the past few months had all been a bad dream.

She would have genuinely appreciated someone noticing that she was wearing her stomach contents and caring enough to mention it just then.

<You are three minutes and nineteen–>

Melitan punched the door controls and the doors hissed shut, cutting the servitor short.

‘He can wait five minutes more for me to get dressed.’

IV

Exogenitor Louard Oelur waited for her in the airlock clean room, his bulk spread over a litter of woven steel borne across the shoulders of six hunch-backed draught servitors. The walls were noospherically proofed. The doors both into the contact laboria and out into the analytica suites were hermetically sealed and could be opened only in alternation. Melitan’s own anti-tracking wetware informed her of the array of auspex scanners and recording apparatus buried inside the walls. Scores of concealed adepts would even now be poring over her body scans and exload signatures. She gave a breathy cough, dislodging a lump of sick from between her prosthetic teeth, and tried unsuccessfully to wipe it on the back of her robes.

She hoped they appreciated what they saw.

The outer airlock door whistled shut behind Melitan as she entered, decontamination sprays that smelled of high-percentage alcohol rinsing her front and back.

A robo-mastiff lunged out of the ethanol mist with a growl.

She flung herself back against the closed door with a startled cry, the mastiff’s chain rattling as it shoved its muzzle into her belly, between her legs, snuffled along both arms. The mechanics of the hound’s thinking processes snarled as it processed its exload samples. She cringed as far back into the door as she could go. But Palpus’ codes were good. It backed off with a growl, disappointment she was sure, and slunk back to its keeper, trailing chain.

Its keeper was a vat-grown colossus of upper body brawn, clad in a harness of studded leather armour. She was female, residually, but so altered by androstane therapies and surgical modifications that gender identification was barely relevant. A fan of electroprobes ran along her bald head, trilling wires strung between them. Her mouth was an overspilling mess of audio-sounders and kill switches. The mark of the Legio Cybernetica was branded into the bare flesh of one atrophied breast. Various cohort and hierarchy sigils decorated what was left of her skin. Her hands had been grafted together and packed in rockrete. The chain that held the robo-mastiff ran straight into her forearms, where it became part of the bone. She needed every last kilogram. The robo-mastiff was built like an attack bike, its default cognisance only barely checking its instinct to maul and rend anything with a noospheric signature.

The five-man squad of skitarii rangers, encased in reflective carapace and with holstered sidearms at least made the effort to scan Melitan unobtrusively.

The Legio Cybernetica keeper made a stuffed-mouth crooning sound, eyes rolling madly, as Melitan tore her eyes away, unpeeled herself from the door and shuffled towards Exogenitor Oelur.

‘You must forgive the security precautions, Magos Vale.’ A viperous nest of mechadendrites undulated out from the exogenitor’s bloated core structure, his secondary head listing from his neck as the swollen magos attempted a shrug. ‘But this is what the logi-legatus sent you here to assess, is it not?’

The cherub servitor droned towards Louard’s litter, chittering away on a binaric register.

Melitan felt a moment’s pain, as if a screwdriver that had already been buried in her skull was being rotated forty-five degrees, as her implants realigned to translate the higher order hexamathic.

<Forgive this unit’s delay. The visitor required re-sanctification and dermal cleansing.>

<Tardiness is repellent to the godly order of the schema. Submit yourself for immediate neural chastening.>

Melitan fought to control her smile.

Her dream was already fading from memory, the eerie feeling it had left in the back of her mind and under her skin almost forgotten. She had become so acclimated to subterfuge that she expected it everywhere. But perhaps Nicco Palpus fretted over nothing, and Louard Oelur really was just what he seemed – the ancient and petty lord of his particular dark corner of Mars. The icon she had glimpsed in his offices could easily have been something left there in error, planted by another, overlooked by a senior magos with more important concerns on his mind.

Who knew what effects the meme-proxy could be having on her capacities?

‘Well, Magos Vale? I trust Tier Zero’s first-line precautions are satisfactory.’

Her eyes drifted back towards the robo-mastiff. It glared back at her with pre-programmed hunger.

‘Exemplary,’ said Melitan.

‘As you have no doubt discerned, the chamber is airtight. It is noospherically dark. There is no way, physical or metaphysical, of breaching containment. You will have noted the baffles in the walls.’ Melitan had not, but looked at them now, rows of tiny holes perforating the metal sheeting. ‘That is the ventilation system. He banged on the wall with one claw-tipped mechadendrite. It responded hollowly. ‘Even the ventilation flows are directionally gated and subjected to vigorous containment. The air supplied to the laboria is on a completely distinct system to that which supplies the outer rings.’

‘Impressive,’ said Melitan.

‘As I believe I informed you it would be.’ His slave head twitched, left to right, as the exogenitor consulted his mnemonic references. His primary head nodded once. ‘Indeed I did.’ At a silent command, his litter bearers turned towards the inner airlock door. The skitarii rangers fell in alongside. The Legio Cybernetica keeper shuffled in behind with a clank of chains.

‘We will begin with a tour of excise and clearing.’

The ranger alpha, marked out by a single white line across his chest plate and a dense array of communications gear on his helmet, stiffened as his systems interfaced with those of the door controls. There was a few seconds’ pause while the authorisations spat through the adjoining control rooms. Melitan bit her lip. Then the big door irised open onto a stub of corridor and another door behind.

‘That is where all personnel are clerked for duty and all equipment that has cleared quarantine is subject to periodic rechecking,’ Oelur continued. The procession filed into the airlock, skitarii first, keeper last, Melitan and Louard Oelur in the middle. The door shut behind them and locked. Her ears popped. She heard the hiss as air pressures equalised. ‘The laboria are held at negative pressure,’ Oelur explained, waving a fat carcass of a hand. ‘For obvious reasons.’

There was a gasp, of relief almost, as the inner door irised open.

Swallowing her nerves, Melitan followed her escort inside.

The lights in this section of Tier Zero were noticeably brighter. The walls were panelled with smoothly interlocking metal plates of a reflective, iridescent alloy. Every section of corridor was joined to the next by a collapsible blast door. Twitching sentry guns watched every approach. Lighting came from lume strips that ran parallel to the floor along both walls. The strips’ proximity to Melitan’s eyes was presumably why their output felt so astringent and bright. The strips broke where they hit recessed doorways, forked into two to run around armourglass windows, intensifying the effect of the light and effectively masking what was inside.

Melitan split off from her skitarii escort to go to the first window and peer inside.

Clusters of robed adepts sat across several metal tables, ferrying trays of some manner of organic material from a dispensary for close-range bio-sensory analysis at their tables.

‘What is this?’

Oelur’s lips peeled away from a cruciform grin.

‘It is the refectory, Magos Vale.’

Melitan suppressed a sudden blush.

‘Forgive my neglect,’ Oelur rumbled, fumbling entirely his reading of her embarrassment. ‘It has been four hundred and eighty-three years since last I ingested organic sustenance in that fashion. You are only recently awoken. Do you wish to break fast before we proceed?’

Melitan’s recently voided stomach knotted in rebellion.

‘No. Thank you.’

V

There were more invasive checks waiting in excise and clearing. Melitan was ordered to spread her arms while lexmechanics and enginseers wielding portable auspex units scanned her. While they fiddled with dials and compared scans, a heavily armed skitarius frogmarched her towards the low arched entrance of the modular tunnel that ran along the near-side wall.

It was dark inside, confined, and filled with the thunderous echo of deep-penetrating scanners. She felt the arcane devices pry into the bone, into the marrow, into the nucleic structure. Her stomach flipped and flopped as the deep booms went off around her. It was inconceivable that such potent Dark Age technologies would not uncover the false augments that Nicco Palpus had installed in her to make her look the part, but their dummy signals were somehow adequate to the scrutiny. She let out a long breath as she emerged, blinking and deafened, from the other side into a thorough patdown from another steel-faced skitarius.

The Voice of Mars’ abilities and resources never ceased to astound her.

Everywhere in the sensor-crowded chamber, adepts and menials were having their equipment and persons probed. The presence of Louard Oelur and, perhaps even more so, the keeper and her robo-mastiff, kept complaints to a minimum.

The second skitarius squeezed Melitan’s arms hard enough to draw a gasp, then sent her brusquely into the primary flow of bodies, ready to receive another.

There was no physical or procedural weakness here that she could see.

She doubted whether Palpus himself could smuggle a microbial spore this far in or out of Zero Tier. Perhaps a real adept would notice something lacking, but given the fact that hundreds of them had to file through this checkpoint daily it seemed unlikely.

What do you want from me? she thought to herself, and immediately cringed, realising that an answer was a possibility and that she would just as soon go without.

The implant containing the Palpus meme-proxy remained mercifully quiet.

‘Are you satisfied thus far?’ asked Exogenitor Oelur.

Melitan noticed that while the skitarii rangers and the keeper had all passed through the auspex tunnel, Oelur and his litter had been waved through the cordon with only the most incidental of sweeps.

‘You could say that,’ she replied as she hurried to rejoin her escort. She felt that an inspecting magos should be asking questions so she thought of one quickly. ‘How regularly must workers submit?’

‘Twice daily,’ said Oelur. ‘Once as they come on-shift and again as they come off. We will survey the dormitory blocks and habitation areas on our return from the laboria.’

Melitan and her procession joined the flow of bowed heads and trailing robes.

None of the tech-priests spoke, but surrounded by the rustling of their robes and the click of metallic parts on the floor, Melitan felt an itch run down her spine. A disturbingly organic phobia that they were indeed communicating, all of them, about her, on a level below her ability to detect. She turned to Oelur, his bifurcated expression presenting its usual split between morbid serenity and a formaldehyde-stricken grimace. Compared to the rest of their detail, who did not share a single expression between them, his two faces were practically loquacious.

The adepts began to peel off. In ones, twos, threes. Recessed doors hissed open, then hissed shut. Lights flickered on automatically, sensing their presence and their movement.

‘I thought there were no higher machine-spirits in operation here,’ she murmured.

‘No exload-capable spirits,’ Oelur corrected. ‘We must still function.’

The exogenitor permitted her to observe some of the tech-priests’ work.

To the uninitiated looking in, it was monotonous and inscrutable. Perhaps it was monotonous and inscrutable to the initiated too, but Melitan had only her own experience to inform her. Individual adepts, largely oblivious to the others they shared space with, shuffled plastekware between benches, operated machines, read off data-slates, occasionally appending the information with their own notations, then returned to moving plastekware about and worked the machines some more.

‘What are they doing?’ she asked.

Oelur snorted, and gave her a look of unblinking scrutiny. She wondered if she had betrayed an ignorance of some secret knowledge, a cipher known to all magos biologis of rank, but the exogenitor turned back to the toiling adepts.

‘NL-Primus does not exist. Zero Tier does not exist. Nicco Palpus could have fired the Dawnbreak Technology into a black hole, but instead he divided it into three and split it amongst those magi he trusted best to contain it. Iron Father Kristos would not allow it to be destroyed.’ His primary head frowned, but not at anything being conducted in the laboria just then. ‘The Iron Hands are useful soldiers, a fifth column to stand between the Legiones Skitarii and Auxillia Myrmidon in the Omnissiah’s hierarchy of war. That is why the position of the Voice of Mars exists. In my lifetime alone I have seen the so called Iron Creed quietly revised several times. But this Kristos is different. He thinks himself more, he thinks his Chapter better, and he would use the Dawnbreak Technology to realise his vision.’

‘How?’

A rattling heave of a shrug. ‘The technology is transformative. It is a relic of the eldar, constructed to inhuman needs at the pinnacle of their febrile imagination and powers, at the very precipice of their descent. Who can say how such alien minds would have meant to exploit it.’ He rapped on the armourglass between them and the laboria researchers with a heavy mechandendrite. ‘Palpus humours the Iron Father for now, carefully, for even Kristos will not endure forever. Such is the nature of warriors. Such is the gift of stability that the Synod bestows upon the Iron Hands through the Voice of Mars.’

Melitan peered through the protective glass at the tech-priests working inside. Hooded. Anonymous. Manipulating their meaningless instruments in their sterile laboria.

‘They study the effects of the Dawnbreak Technology on living flesh,’ said Oelur. ‘And on technology, both Martian and xenos. I believe that Fabricator-Locum Hyproxius Velt was engaged in similar investigations on Thennos. Exar Sevastian I do not know, but I doubt that his facilities on Fabris Callivant would be suited for anything beyond mere containment.’ He sniffed, musing. ‘He received the lesser cache of the three.’

‘And…’ Melitan hesitated, unsure if she wanted to ask the question, but knowing it had to be asked. ‘Where are the test subjects?’

VI

Glass-fronted cells hung over nothingness either side of a lengthy observation derrick. Scrutiny was meant to work in only one direction, Melitan knew, but the bullet-like focus of so many stimulus-starved eyes had a force that was physical. The hangar-like space was cathedral quiet, layered in dark. Multi-focus stab-lumens ran from a creaking gantry. A susurrant mutter rose from the binary infocytes embedded in the data analysis pits that hung under the loosely tiled floor. Numerous consoles put out a gritty pall of illumination, but it was barely enough to show up the masked adepts that worked at them, the slow ivory click of their runekeys a devotional sub-dialect of its very own.

The cells themselves were large, more spacious than Melitan’s single cell in the outer dormitory blocks. The better to study their behaviour.

The first contained a human male. He lounged soporifically in an unmade cot. He was naked, a consequence of choice rather than imposition for unworn clothes lay strewn about his cell. Melitan could see drained electoos and numerous low-grade bionics on his body. An adept of the Mechanicus. A volunteer, perhaps. The skin around the augment attachment sites bore evidence of self-harm, gouge marks from teeth and fingernails as if he had attempted to pry the devices from his flesh.

Some uncanny confluence to a thing she had seen in her dream the night before sent a shudder through her, and she allowed Oelur and his guards to lead her on.

The next cell contained an unpainted Sentinel walker, apparently fresh from the manufactory lines. Its weapons had not been fitted and its machine-spirit did not appear to have been drawn forth to awaken the shell. Melitan made the sign of the blessed cog at that act of mercy and moved on. The next harboured a bloody smear on the glass and a lump of something non-specific on the floor.

‘The greenskin races do not react well to the technology,’ said Oelur. ‘We continue to hold it under observation in order to study any post-mortem influences. There appear to be none thus far.’

The derrick seemed to continue forever. Lit cells lined the walkway like a hall of horrors. A terrible fascination drew Melitan’s gaze to each and every one. <Be wary.> The electrical pulse from Palpus’ implant burned the warning into her cerebral cortex. Her footsteps wavered, rattling the flooring, as pain, however localised and brief, wrote the meme-proxy’s admonishment into her synapses.

‘Do you tire?’ asked the ranger alpha, helping her refind her feet with an uncommon kindness of touch.

‘No,’ she smiled back. ‘I’m fine.’

Other cells contained more men. More women. All in various states of spiritual degradation and material undress. Some stared into space and cut at themselves like the first, but others maniacally laughed, cried or raged at their confinement. Melitan started from the handrail as a woman hurled herself at the glass of her cage and babbled.

‘Should these cells not be soundproofed?’ she asked, her heart racing as she allowed the ranger alpha to lead her away.

‘If that is your recommendation then it can be arranged,’ Oelur sniffed. ‘But the purpose of this confinement is observation.’

Others were comatose, hooked up to wittering chirurgical machines via murky intravenous lines. Plastek tubing splayed from their bodies like a peeling chrysalis. Melitan could read some of the rune notations on the chemical tanks. Some were formulated to hold the body alive in spite of brain death, others were concocted to keep the brain alive while the body decayed.

She saw representatives of dozens of alien races. A borous threll. A demiurg. A gretchin – its cranial contents spoiled over the glass. A worker-form chrome. Others she had never encountered before or that she knew only through textual descriptions of rogue traders and magos explorators from centuries or millennia past.

There were scores of cells. Hundreds.

Thousands.

The derrick stretched off into darkness.

She paused to look at one. Oelur issued another sub-vocal command and her escort clanged to a halt. It held an eldar female. She stared back at Melitan with almond-shaped eyes that gave away nothing. She was beautiful, both from an objective and an ascetic standpoint. Her features were sharply symmetrical, her hair was the colour of ochre, her skin like cream. She was so very nearly human, and yet hauntingly abstracted from it. She sat cross-legged on her bed, hands on her knees as though meditating, just staring, utterly unconcerned by her nudity or her confinement.

‘Subject one-two-four-one,’ said Oelur. ‘Eldar are notoriously difficult to capture alive, but it was essential for us to employ at least one as a control subject.’ He extended a mechadendrite to prod the glass, making the cell sway on its wire. The eldar did not react. ‘Designation, Harlequin. Taken by skitarii forces during a raid on Phaeton.’ He withdrew the extensor. ‘A proportion of the individuals you see here have had no contact with the Dawnbreak Technology at all. They are present simply to negate the symptoms of confinement as a causal factor from any observed behaviour.’

‘She does not seem to be affected,’ Melitan said, unable to break the eldar’s gaze.

‘Not in any way that it allows you to see. But the eldar xenos are uncannily adept at segregating body from mind. This is why they are so resistant to physical interrogation. It is quite fascinating.’

‘Fascinating. Yes.’

She stared at the eldar. The alien’s lips parted, slowly, shaping words that she had no conception of. One corner curled into a grin.

‘Did you see that?’ Melitan turned to Oelur, but the exogenitor did not appear to have noticed. When she turned back the eldar had fallen mute and was still again.

If it had ever been otherwise.

‘These subjects will never leave their cells,’ said Oelur, his litter-bearers already turning away from the cell and bearing him on. ‘Containment of the technotheurgic corruption is assured. If a new test occurs requiring the participation of additional subjects then we simply install another cell.’

Melitan moved after him, peeling her eyes from the eldar’s face only when she was out of sight. ‘And… what is the nature of the corruption, exogenitor? How does it spread as it did across Thennos?’

‘That is the question, is it not?’

Oelur’s two heads turned until they were both facing ahead. Melitan saw that the track of illuminated containers came finally to a halt somewhere in the near distance. Perhaps another hundred or so cells down. In the dark beyond them stood a goliath set of structurally reinforced and noospherically barred containment doors.

Pain wormed through Melitan’s skull to reiterate its earlier message.

<Be wary.>

Oelur cracked a conspiratorial smile. ‘Would you like to see it?’

CHAPTER NINE

‘One of my ancestors described the tournament as the stimulant of the aristocracy and the opiate of the peasantry. It is time now for both.’

– Princeps Fabris

I

The Shield of the God-Emperor was less than two-thirds the tonnage of the Omnipotence, but that was not the impression that greeted Jalenghaal aboard the Hospitallers’ hallowed flagship.

She was the sword of angels, seven kilometres of white armour so brilliant it looked as though she were on fire. Numerous golden aquilae emblazoned her length, a trillion words of scriptural writ inscribed in intaglio, as if the entire Corpus Divinatus and its compendium codicils had been transposed word for word, scale to scale, onto ceramite. Her internal splendour was no less magnificent, a gothic fusion of cathedral and mausoleum symbolising both celebration and interment. As her hull plating carried the scripture so too did her bulkheads. Her columns and braces glittered with golden lettering, every thread of every screw wound with infinitesimal words of valediction, malice and prayer. Similar decorative motifs recurred. Crosses. Scythes. Winged angels. Doorways surmounted by cracked skulls irised open like portals to the underworld, leading onto corridors bedecked with ever graver and more morbid imagery. Every passage was a reliquary. Lit by candles, protected by force field and armourglass, the bones of heroes, drops of blood preserved on strips of parchment, and weapons with which qualitatively valorous deeds had been performed in the name of an abstract creed, all sat in quiescence.

The bridge itself was a centre of worship first and of command second, and made the preceding kilometres of ship seem secular by comparison.

A million candles burned in sconces, cradles and in the hands of serfs who served no other purpose than the bringing of light. Despite them, it was dark, and Jalenghaal wondered if that was a deliberate metaphor for the work the Hospitallers performed on behalf of the Master of Mankind. Choirs of gene-eunuchs a thousand strong delivered dirgeful hymns of deliverance through duty’s end, amplified by the vast dome into an oceanic elegy of lament. The frescoed rotunda was replete with skeletal grotesques, shedding their liquefied flesh and shielding their skull faces from the golden brilliance of the Corpse-Emperor enthroned at the oculus of the dome.

At the sound of his guest’s approach, Chapter Master Mirkal Alfaran turned.

He was armoured, but unhelmed. His face was powdered white, eyes ringed with kohl so that his bald head resembled a skull. His armour was a penitent’s white, gold inlay and parchment strips, enough for a dozen tomes of scripture, burning under the candlelight. Hand-crafted aquilae clattered on strings as he moved. An enormous, two-handed power sword with the Hospitallers Cross at the crosspiece was mag-locked across his back, swathed in an elaborate scabbard that resembled a pair of angel’s wings. A single gold ring strung with actual white feathers pierced his ear.

For all the Chapter Master’s eerie sovereignty, Jalenghaal’s interest lay with his seneschal.

Venerable Galvarro was a Dreadnought. He was reputed to have advised every master of the Hospitallers since their founding as a Chapter almost a thousand years prior, and his armour was a sarcophagus fit for the interment of a hero. The pearly white ceramite was covered in plates of ormolu bearing mezzotints of heroic scenes. Pius and the Emperor. The Emperor and Horus. Dorn bestride the walls of Terra. Unknown heroes engaged in unsung acts across the deep history of the Imperium. Gilded fretwork encircled his weapons and his feet, like the work of a spider that spun gold in place of silk. Atop its sarcophagus, framed within an ornate pair of angel’s wings and haloed by a death’s head, a carillon of golden bells sang dolorously with every steady breath of the Dreadnought’s living power, a panegyric without end for the fallen warrior within.

That was simply the sound that celebrated his existence. When he walked to war in earnest, the bells would sound a very different note.

‘Iron Father Kristos,’ declared Alfaran, jarring Jalenghaal for a moment, a moribund sweep of one gilded arm encompassing his vessel. His voice was a whisper. As though the Emperor listened and he would rather He not hear. ‘We welcome the sons of our father’s brothers, and are humbled that you would join us for the return to Fabris Callivant. Your timing is propitious. We have much to prepare and very little time…’

>>> END OF SIMULUS.

Jalenghaal’s eye opened with a start.

Neural restraint plugs tugged at the back of his skull and the roof of his spine as he instinctively tried to struggle free. He could taste blood in his mouth. But with enervated swallow muscles and no proper mechanism of expectoration, the fluid trickled through the slits in his facial grille. A passing adept wiped it from his face for him. Coolant vented from the simulus alcove and turned to steam in the hotter air. Shrugging off the neural plugs and adaptor circuitry he clumped out of his alcove, scattering the machine adepts fussing over inload-exload hardpoints, and glared down the line of alcoves.

The Garrsak clan embraced simulus technology like no other. Or so Jalenghaal had believed before he had set foot aboard the Omnipotence.

Scores of alcoves, enough for half a clan company, lined a walkway several hundred metres long. The intervening space was taken by power generators and data converters, great baffled coils of primary and secondary surge protectors. Loops of wire scrambled up the walls like creeping vegetation, and criss-crossed the air like a net. The walkway itself was nothing of the kind. It was a dump for a mass of thick, brass-ribbed cables that connected individual alcoves to the meme-stacks. To stand within it was to be shrunk to a millimetre scale to stand within the circuitry of a doctrinal wafer. It was enough that the manual tasks of command entry and cable transfer had to be performed by an automated assemblage of hooks and claws operating from a network of overhead rails. Hymning processionals of tech-priests, led by flesh-spare mechardinals in flapping vestments and mitres ran along them in shuddering, open-topped cable cars. The meme-stacks themselves stretched high towards a distant ceiling, shrouded by hyper-coolant like clouds clinging to the walls of a cathedral spire.

Despite the heavy Mechanicus presence and legions of servitors, Jalenghaal had yet to see any evidence of an actual crew.

Emerging from their alcoves stumbling and disoriented, the rest of his clave looked around as he did.

Burr stood in the alcove directly opposite, buried to the waist in electrically glowing smoke. Lurrgol looked down from the far end of the long line as if he might drift away. Borrg, unhelmed as was coming to be his preference, was grinning widely, looking up at Strontius and trying to put words to his excitement.

‘Simulus is no substitute for real training,’ Thorrn complained.

‘On the contrary,’ said Jalenghaal. ‘It is more efficient than physical practice. You will adapt.’

The very act of simulus changed a warrior. Subjecting him to the galaxy of woe and experience could not help but degrade his notion of self. With good reason were the Garrsak clan seen by their brothers as little better than robotic killers. ‘Garrsak obeys’ was the mantra. Simulus, Jalenghaal was coming to realise, was part of the reason why.

Garrsak and Raukaan held that in common.

The doubts were Stronos’ doubts. Or they had been. They were a part of the clave now. ‘Garrsak’ in old Reket Medusan meant unity, and to be Clan Garrsak was to be one. That, Garrsak and Raukaan did not hold in common. The Raukaan clan was Iron Father Kristos. The Garrsak clan was a gestalt of them all, a pyramid of machine-linked souls with Draevark at its pinnacle, each warrior dependent on the strength of every other. It was what made them strong.

It was also what made them weak.

Stronos had understood that from the beginning.

‘Why does Kristos exload his meme-files of the Hospitallers flagship to us?’ asked Burr. ‘We are here to fortify Fabris Callivant against the orks, are we not?’

‘That is my understanding,’ said Jalenghaal.

‘Why then does the Iron Father want us to experience the inside of the Hospitallers battle-barge?’

Jalenghaal did not answer.

He did not have one to give.

II

Kardan Stronos hunched under the hard metal of the doorframe, wariness sparking into interest as he found himself in Magos Instructor Yuriel Phi’s private reclusiam. Curiosity, as he had often been reminded, was his own personal weakness. The chamber belonged to a separate wing of the facility to the neophyte’s dormitory cells and common areas, barely accessible at all to one blessed with Adeptus Astartes physiology and armour. Stronos envied the magos her sanctuary.

The walls were lined with aluminium shelves of identical length and spacing. The bronze-spined tomes and archeotech curios salvaged from the facility’s older, failed sections were fastidiously arranged. Scholarly interest? Ancillary projects? Stronos could only speculate, but he doubted that the magos’ day began and ended with the hours of instruction between first and last prayers.

Phi made her way to a sturdy metal table that stood in a circle of light from an overhead lume source.

Hinged clamps glinted like fangs in an open jaw, a pair at the foot end, another, larger, at the head, two more off centre to either side. Restraints. A hooded menial was tightening the screws that secured the clamps to the hinges using a manual driver. He shuffled off without speaking as Phi began to tap at the set of ivory runekeys set into the head end of the slab. Stronos followed the departing menial with his eyes. He thought he recognised him from the calefactory, but could not be sure. Most mortals looked vaguely alike. Disregarding him for now, Stronos looked up, his bionic shuttering against the lumen’s brightness. A nest of folded, skeletal servo-limbs hung from the ceiling, like a dead spider withered in the sun.

‘Why am I here?’ he asked.

Phi looked up from the runebank. Cable dreadlocks fell across her face, diffracted the glow of her eyes. ‘Why do you socialise with the other aspirants? It serves no purpose.’

‘They are not as I thought they would be. Perhaps I would understand them better.’

‘Spoken like a scholar rather than a warrior.’

‘Is it not within us to be both?’

‘Why?’ She shrugged, cables sliding from her shoulders and down her back. ‘You are an Iron Hand – you have the legions of Mars to fill the role of the scholar for you.’

‘Perhaps I am unconvinced by that arrangement.’

Phi bared her teeth, white enamel against the energy-damping metal of her exo-carapace. Not for the first time, Stronos was struck by the sheer wattage of personality that was put out and somehow contained within her tiny frame. ‘Maybe. Perhaps. Has anyone ever mentioned that you are slow to cement an opinion?’

‘Yes.’

‘Good.’

Stronos’ finger traced the silvered edgework of his girdle plate. Barras’ knee had put a serious dent in it, but Clave Jalenghaal’s exloads continued to trickle-feed into his systems from the data-tether there, warped and time-lagged by the distances involved, a slow poison of doubt and mistrust.

‘Why am I here?’

‘There is no need to be so suspicious,’ Phi chuckled. ‘I trained Feirros, and Fell, and Bannus and Gdolkin and Verrox, and Kristos.’

‘And Ares?’

She smiled coyly. ‘Just how old do you think I am?’

‘Are you inviting me to guess?’

The magos laughed at that. ‘Kristos was the same, you know. He too demanded answers, was never satisfied when he had them.’ Stronos’ one eye glowered at the implication. ‘You are not like the other aspirants here. You do not study solely to become a Techmarine. Worthy as the pursuit may be, it is as deep into the mysteries of the Machine-God as those not of the Iron Hands may go. You are to become an Iron Father, a leader of your world, the custodian of secrets that the ancient alliances between your world and mine have opened to you. It demands special instruction.’ She tapped meaningfully on her table. ‘It demands special upgrades.’

‘I have entered the Eye of Medusa,’ Stronos muttered, circling the operating slab.

He had seen how the Iron Fathers had been able to interface with the ancient technologies of the Eye and with each other to forge a network in which communication was almost instantaneous. The assembled Iron Fathers had been able to coordinate with allies, debate complex points of dispute with rivals, all while simultaneously addressing the Council in archaic spoken Medusan. As an example of how proprietary technologies could be exploited to improve the efficiency of the Chapter’s affairs, it was a marvel, and yet…

He folded his arms over his chest-plate.

‘The Adeptus Mechanicus provides and maintains our equipment. The Voice of Mars votes on the Iron Council. The magos calculi advises us on all decisions.’ He used the word ‘advise’ loosely, for most iron captains took the calculus as writ. ‘You instruct our leaders.’ His facial muscles struggled with a frown. ‘And you modify those leaders’ brains in the process.’

‘You make it sound so sinister.’

‘If our positions were reversed, would you not think so?’

‘Were our positions reversed I would approach your question logically.’ She raised a finger. ‘You speak of a conspiracy, but there is no conspiracy, Kardan. There is almost never a conspiracy for they are impossible to maintain.’ A second finger. ‘Furthermore, as great a force as a Space Marine Chapter represents in its own fief it is insignificant before the might and reach of Mars. There is nothing you have that we could not take if we so decided.’ A third finger went up. ‘And point of logic number three. Mars honours its alliances.’ She studied him a moment, eyes blinking, switching colours, the slab still between them. ‘The question then becomes – do you wish to assume the rank of Iron Father?’

Stronos nodded grudgingly.

He had entered the Eye of Medusa, and had seen all that was wrong with the workings of the Iron Council. In the disastrous aftermath of the battle on Thennos, his mind had conjured an apparition of Tubriik Ares who had persuaded him to pursue the fallen Ancient’s mantle. After his convalescence, he had made a similar vow to his friend Lydriik.

‘I made a promise.’

‘Do you wish to change how the Iron Hands are ruled?’

The question took Stronos aback. From a certain perspective, every individual Iron Hand existed in a perpetual state of improvement, but change, principally and collectively, was anathema. For the last one hundred and fifty years of Stronos’ transhuman existence he had watched the Iron Council sclerose under the paternalistic indifference of the Voice of Mars. He had bemoaned it, derided the weakness of the Iron Fathers, but change it? He had never entertained it as a possibility.

When he said nothing, Phi patted her hand on the slab. He wanted to like her. She was competent, wise, inhuman, but ‘never trust’ was the first dictum of the Scriptorum of Iron and it rang in Stronos’ head.

He had learned on the battlefield and in the ruling sancta that the interests of Medusa and Mars were seldom as closely aligned as they appeared.

‘Very well,’ he said. ‘Make your upgrades.’

Magos Phi made to speak.

‘But. I will summon my equerry-servitor. It will observe and record the entire procedure.’

‘Agreed.’

‘And I will remain conscious.’

‘That would be inadvisable. The risks would be tremendous. To say nothing of the pain.’

‘Those are my conditions.’

‘It is your flesh,’ the magos sighed. She clapped her hands for her attendant and Stronos hauled his massive iron-and-ceramite frame up onto the slab.

The menial fluttered in, closing the clamps over wrists, ankles and forehead, and slotting in the pins to lock them shut. As the man bent over Stronos’ face, he saw, briefly, the flicker of an electoo, that strange, inverted symbol.

‘Well then,’ said Magos Phi, hands resting lightly on the runekeys while she waited. ‘You will experience pain almost immediately.’

III

With Rauth, Laana, Bohr and Harsid all aboard the shuttle craft, Little Grey was cramped to say the least. The late Epicurate Hypurr Maltozia XCIII apparently exhausted his imagination reserves with the naming of his ship. The lightweight vessel bumped through spoils of atmospheric turbulence. The transorbital ship movements resembled cyclones, tapering into orbit from the principal baronies on the planet’s surface. Landers frantically moved the last payloads of troops and equipment to the ground while fleet strategos and administrators moved back up. Departmento Munitorum operatives in airspace control turrets shaved every available second off their departure windows until the take-off of one ship and the landing of the next occurred practically concurrently. Collisions, even with augmented pilots, were an inevitable hazard, and added more to the sense of bedlam than they took away.

Confirmation requests and wide spectrum code-blasts from the control turrets lit up Little Grey’s cockpit boards, but with so much traffic it was easier to ignore the automated challenges than reply. They had the requisite codes, of course, but quicker simply to slip through the net.

They had had about forty-eight hours before the greenskins arrived.

Now they did not even have that.

Kristos was coming. And just as he had with Dawnbreak one hundred and fifty years before, he would salvage the xenotech and leave the world to burn. Not that I could care less about Fabris Callivant, or Dawnbreak for that matter, but I’ll not be beaten. Not by him. His feelings towards Iron Father Kristos were murky and confused. Dwelling on the subject for any length of time made his skull ache. He dabbed at his nose with a finger. No blood this time. He looked out of the window and tried to think of something else.

‘Commencing our final descent,’ said Harsid.

Clouds boiled up from beneath them, followed mere seconds after by the first lashings of rain. This is Fabris Callivant. Of course it’s raining.

The Death Spectres captain was armed and armoured and ready for combat, helmet sealed, sleek black plates drinking in the low-level cockpit lights. Laana was strapped into the co-pilot’s throne. Mohr was in the back, setting up his equipment. Because someone’s going to get hurt. Ymir was still on the ship. The Wolf had complained bitterly, but someone had to stay behind and, as Harsid had put it, it wasn’t going to be Harsid.

Rauth held on to the ceiling grips with his metallic hand, crushing the leather in its grip, swaying with the atmosphere’s attacks on the unarmed craft.

He had never actually engaged in a full-scale combat drop before, so could hardly draw the comparison, but it seemed to him as though Little Grey was compensating for the absence of hostile flak admirably.

The clouds began to disperse. The deluge grew more insistent. A sweep of crusty, barren terrain scuffed into soft focus beneath him.

Fabris Callivant had been stripped millennia ago. Her crust was a warren of former extraction tunnels. Even her mantle had been tapped, episodes of high-explosive mining breaking open entire continental plates to eke out what precious minerals she still held close. That too was in the past, but the geological scars were still visible from the air. There was no vegetation. Heavy acidic rains scoured the surface daily. The only feature to disturb the barren vista of craggy grey was the slight indent of road, the bristling of hab towers and weather shields that marked one of House Callivant’s vassal outposts. To the west, a string of low, humpbacked mesas stood up against the environmental scouring. They were in darkness, the rising sun a half-ring of acid pink beyond their peaks. The near slopes glittered with hive lights, the capital of some petty barony whose fief bordered the royal tracts of proud, beggared, Fort Callivant.

The geology enlarged as the shuttle dropped, the horizons hurtling in from all sides. Fort Callivant itself rose firmly into view.

The planetary capital was a rising shard of rust-brown ferrocrete and grey plasteel. Rainwater streamed from its pitted outer shell, dumping it in edge-of-the-world cascades onto the basement dwells and sub-tenement striae, homes to tens of millions that sprawled into the surrounding landscape under the hive’s own vertiginous mass.

Peering through the triangular side windows, Rauth tried to catch sight of the Princeps’ shard palaces through breaks in the rain.

The tourney fields of House Callivant were reputed to be an awesome spectacle.

>>> HISTORICAL >> THE BATTLE FOR FABRIS CALLIVANT, 212414.M41

Burning drive plasma at several thousand degrees beyond tolerance [ACCESS INSTRUCTIONAL >> RITES AND OBSERVANCES OF VOIDSHIP DRIVE FUNCTION] had brought the Adeptus Astartes flagships to Fabris Callivant in less than twenty hours. The staged withdrawal of the Alloyed, the Brutus and the ships of the Hospitallers’ fleet held the orks at bay, but the orks’ numerical advantage was too great, and more ships continued to arrive every minute. The strike cruiser Golden Soldier was boarded and subsequently destroyed while covering the withdrawal. The Last Rites and the Clan Borrgos frigates Mount Volpurrn and Corpus Mechanicus disappeared from auspex somewhere between the sixth and seventh planets, their wrecks lost to the interplanetary gulf. Contemporaneous accounts from Magos Qarismi predicted the first exchange of shots between the ork invasion fleet and Darkward to occur eighteen hours and twenty-five minutes from that point.

The magos calculi would, of course, be proven entirely correct.

IV

The hemispherical arena stood open to the murderous outpourings of the sky, jutting from the side of the artificial mountain like an armoured plate from the shoulder of a Space Marine, ringed by the torrential roar of a waterfall. Tiered seating for a hundred thousand aristocrats and peasants-elect climbed its leeward side, built into the eastern precincts of Princeps Fabris’ ancestral abode. Two-score brightly coloured banners replete with technomythic symbols and Dark Age heraldic icons fluttered limply in the wind and rain.

A quartet of Thunderhawk gunships, three black, one white, descended towards the arena basin. Four colossal Knights, the deep burgundy of their heraldic war-plate replete with honours, stepped out from under their banners and fired off a thunderous salute, the noise of heavy stubbers and Icarus autocannons temporarily drowning out the orchestrated cheers of the Callivantine citizenry that had been herded into the sodden arena seating.

The gunships touched down for a matter of seconds, and Space Marines piled out. The mixed squadrons of Imperial and Taghmata interceptors flashed overhead, pursued by a rippling, rolling sonic boom as they split and rocketed back on a loop towards the exosphere. Jalenghaal’s boots thumped on the hard, cratered granite of the arena.

The rain danced on the expanse of ground, splashing and pooling in pockmarks and craters. It beat against Knight armour, fizzling to steam on ion shields.

Targeting objectives and tactical information blinked through the visual mess of Jalenghaal’s displays, picking out power sources and weapon profiles. His systems muted the roar of the crowd, dulled the thunder of the Knights’ portable artillery to a quiet ache. And he manually sorted his displays one threat at a time.

<Demonstration aspect,> he snapped to his clave in binaric cant.

Lurrgol was drifting at the back of the column, and the timing of the others was becoming ragged as a consequence. Jalenghaal’s annoyance was not going to cure his brother’s episodes of confusion, but it seemed that once one emotion got in, the gates were opened to the gamut.

Kristos had chosen to represent each of the Clans Raukaan, Garrsak and Borrgos with a full clave led by Sergeants Ulikar, Jalenghaal and Tartrak respectively. They plodded mechanically behind their leaders.

Alongside the Iron Father went Apothecary Dumaar, Iron Chaplain Braavos and the skeletal figurine of Magos Qarismi. Chapter Master Alfaran was accompanied only by his Dreadnought seneschal, Galvarro, and a five-man honour guard of morbidly outfitted veterans. Jalenghaal recalled a mention of them in Kristos’ simulus files, an elite unit that stood separate from the Hospitallers’ peculiar three-company structure called The Vigil.

Martial displays were not something to which the Iron Hands were frequently disposed, but forty Space Marines was no small show of strength, and Jalenghaal did approve of demonstrating strength.

Greater worlds than Fabris Callivant had been brought to heel with less.

There was a shuddering as the thousand year-old stanchions holding the arena rockrete above seven kilometres of aching nothing took the strain of four moving Knights. They pincered the Space Marine column.

Another group closed from the opposite direction.

On an ordinary meet day, the tunnel that ran through the lower middle of the colosseum’s seating would have been for the passage of tournament Knights and, occasionally, captured xenos monstrosities from House Callivant’s distant warzones. Today, a small company of human dignitaries and skitarii legionaries marched through the cavernous structure and under the raised portcullis, instantly bedraggled by the rain.

Two men led them.

The first was an older man, insofar as Jalenghaal could judge, somewhere around one or two hundred years of age, with the stretched, colour-drained pallor of late-stage rejuvenat dependency. Princeps Fabris himself. He was shorter than Jalenghaal had expected from his battlefield reputation, though of course it took no heroic build to command from the Throne Mechanicum of an Imperial Knight. A prominent lower jaw and a thick bottom lip made him appear somewhat simple. A genetically misshapen lump of a head was peppered with a recently implanted crop of greyish hair. His declining physique was held in by a maroon-and-sable armoured bodyglove, flush with gold braid and ornate battle honours.

The other was a tech-priest of august rank and, judging by the improvements he had made to himself, warlike aspect. The dense material of his robes scattered Jalenghaal’s auspex probes and denied further intrusion.

The two parties met under the fluttering pennons and downturned weapons of the Callivantine Knights. The rain lashed uncaringly across them all.

‘I am Princeps Fabris of House Callivant, sixty-fifth of that name,’ the old man declared, the booming diction of a master orator emerging from the inbred bulge of his lips. He executed a bow, first to Alfaran, and then again to Kristos. ‘I am honoured to bid you both welcome to my world.’ He straightened and smiled, as if that were the formalities dealt with, and spread his hands towards the Knights that flanked them. ‘We have prepared an exhibition tournament in your honour.’

Alfaran raised a kohled eyebrow.

‘Now?’ asked Braavos

Jalenghaal watched Kristos. The Iron Father said nothing however. The glow of his optic slits cycled, a mute display of local omniscience that was clearly having an unsettling effect on Fabris’ human staff.

‘Now more than ever!’ Fabris declared, his altered psychology seemingly immune to the effects. ‘Let our people see the might of their Knights in action!’ He lowered his voice to a conspiratorial whisper that only the genhanced acuity of a Space Marine would detect. The gathered Adeptus Astartes towered over him, the way gods were made to tower over mortal men, but he spoke to them as he would from the Throne Mechanicum of an Imperial Knight. ‘One of my ancestors described the tournament as the stimulant of the aristocracy and the opiate of the peasantry. It is time now for both. And all that must be discussed can be discussed while needs are succoured, would you not agree?’

Alfaran nodded in agreement.

Kristos, still, gave no reaction.

‘It seems you have considered everything,’ said Magos Qarismi, smoothly.

‘You have remade yourself substantially since Columnus, Kristos.’ The tech-priest that had entered the arena with Fabris clanked ahead of his skitarii bodyguards. ‘I approve.’

Princeps Fabris executed a half-bow, and when he rose, he held both arms extended to present his companion. ‘Forgive me, but I understand that my good friend and ally Fabricator-Locum Exar Sevastian requires no introduction.’

V

Exar Sevastian’s forge-temple was not one building. It was a tumorous conglomeration of manufactories, refineries, steaming rad-bins and worker habs, sprawled over half a kilometre and through several vertical tiers. Dirty-faced men, women and children moved through the fumes, crunched in like scrap in a compactor. Harsid had remained with the shuttle, as had Mohr. The greenskins aren’t so close yet that a pair of Deathwatch Space Marines can move through the slaveholdings of the fabricator-locum unnoticed. Nor were landing zones so abundant that an overworked aeronautica controller would not look to have the craft removed, authority codes or no authority codes, if it was not guarded.

‘There is no more time left,’ Harsid had told Rauth as he and Laana had disembarked. ‘We must go in, grab our man now and find where the Dawnbreak Technology has been hidden. Either that or we take our chances with Kristos and the Omnipotence.’

No thank you.

The structure that Laana had brought him to was to the side of a condemned storehouse. Khrysaar is in there, somewhere. The sloping metal and close tin walls funnelled the aircraft noise into the alleyways, clashing there with the clangour of the manufactories. Rusted scaffolding clung to the corrugated walls. Rauth could not tell which was responsible for holding up which. Perhaps both contributed a little. Warning posters peeled under the incessant rain, marking the structure for repurposing, but the work schedule had obviously slipped as the Callivantine foundries struggled to maintain ancestral levels of production. The need for new storehouses was not what it was.

The assassin approached the single guard on the door.

He was a big man. Abhuman big. Almost as large as Rauth. His face was flattened and broad, blotched like a rusty shovel. A thick metal band rimmed it like a bandana, machined into the bone by thick screws. His graft-swollen chest was criss-crossed with red leather straps and he hefted a stripped-down version of an ogryn ripper gun.

Rauth grunted and shut his eyes. I’ve been here before. A memory of this man bubbled up from his subconscious. He saw himself dropping a silver guilder into the muscle-brute’s open palm, a toothless smirk, being ushered inside, an utterance of ‘He’s expecting you, Janis’, then feeling afraid. He shook his head and stared hard at the wall. Rainwater ran down the old metal in rivulets. It spotted his eyelashes as he blinked. The switched cog emblem of the Frateris Aequalis had been spray-painted underneath the flapping end of an old hazard poster. They really haven’t been trying to hide, have they? Yazir has found the place, all right.

‘The pits are full,’ said the guard, slurring his words, as if his tongue had been subjected to the same muscular over-growth as the rest of his body. ‘And the magi aren’t in the habit of picking up meat at the door.’

Laana leaned in. ‘Two guilders.’

‘Five.’

‘Three.’

‘Five.’

‘Four.’

The gene-bred colossus cracked a grin. He held a chewed stub round between his teeth. ‘Six.’

Not as stupid as he’s been made to look.

‘All right,’ Laana grumbled, fishing in the pocket of her underlayers. She had shed the guise of the House serf for this expedition and had adopted instead the garb of an off-shift manufactorum labourer: a baggy umber jumpsuit plastered in rad sigils and draped in a waxy shawl. She opened a purse and dropped six silver guilders in his hand, one at a time, looking over her shoulder all the while.

‘In then,’ said the guard, thumping on the door with the butt of his ripper gun. ‘Ask for Armedius. Tell him there’s been a logging error.’

Thanking him, Laana turned back and whistled. Rauth suppressed a scowl and lurched towards her. Just another cybermantically animated piece of skin for the pits.

The storehouse receiving chamber was a smoke-filled sump of moral corrosion and material decay. Men and women in oil-stained overalls stumbled from push to shove, slurring greetings and curses and racing one another headlong for the proverbial gutter. A display of cyborgised gladiators were lined up below a clacking flapboard. Burned, yellowed, infected hands pawed at the bodies. Drooping eyes. Drooled utterances of wonderment as fingers pinched at smooth metal and gene-hardened musculature. A woman hobbled towards Rauth, only to veer away, a flicker of transhuman dread confusing the self-administered befuddlement in her eyes.

Rauth clenched his fists. He despised the closeness, the scrutiny. The warmth of so many touching bodies was exacerbated by his genetically lowered core temperature, making him feel several degrees too hot and emulating the feeling of anger.

Emulating.

Of course.

An echo sounding of mangled binaric clicked from somewhere in the lho pall and the school of bodies dispersed.

A tech-priest shambled towards Rauth. Armedius? Rauth frowned hard to keep his expression from changing as another bilious spew of remembrance threatened. This one did not arise from the augmentician Janis Gelt, whom he had consumed earlier. He could feel his bionics seizing, illogic loops of resentment and loathing causing them to clamp down hard. Blood rushed behind his ears, driven not by a pumping organ but by a mechanical motor with a spirit of its own, and that spirit was offended by what he was seeing. The tech-priest was a shabby creature, a scavenger insect evolved to an existence in the human swamp. His trailing robes were mouldy and full of holes. He reeked of contaminated spirits. The emblem of the Frateris Aequalis had been stitched into his robes in yellow thread.

In your own house, Sevastian. For complicity or inaction, there is a reckoning coming for you.

The priest held up an arm tool and sprayed Rauth with diagnostic lasers. He issued a blurt of scrapcode, then stencilled the numerals seven-seven-five on Rauth’s chest. ‘Apologies, Mistress Valorrn,’ he said. ‘The logging error has been rectified. Deposit your fighter in bin iota.’

Rauth felt his fingers digging into the skin of his chest above his bionic heart. The urge to rip out the mechanical motor was almost there.

Almost.

There.

With an epileptic jerk of the head, Rauth forced his fingers to unclench.

<What is our plan?>

Laana glanced sharply back at him. She could receive binaric signals, but could not send. She spoke into the thick collar of her shawl, trusting to Rauth’s hearing to pick it up over the din. ‘Once inside I will assist Yazir in searching for the adept you described from the augmentician’s remembrances. Then we will put him to the question.’

<And my part in this?’>

She turned fully around and looked up. ‘Maintain the disguise. Fight whatever they put against you.’ Her sudden smile was like splintering ice. ‘And try not to die before we have him.’

VI

Fabris’ skitarii cohort fanned out onto the armoured dais, weapons primed and humming as though expecting lurking foes even here in the heart of the princeps’ own amphitheatre. Jalenghaal behaved no differently when he, Tartrak and Ulikar followed them through. The platform was a hefty cutaway set directly above the arena tunnel. Tiers of seating climbed stepwise left and right, a transparent dome of age-splintered armourglass sealing the dais against the changeable nature of the elements and the Callivantine nobility. The rain drummed on the glass, a seditious mumble that ran through the enclosed sphere. The cyborg legionaries chittered in code before turning on their heels and training their guns inwards.

<I have brackets on the skitarii,> canted Tartrak.

<Here also,> Ulikar returned.

<I have the princeps,> added Jalenghaal.

Ignoring the ready display of weaponry, Princeps Fabris strolled towards the grand table overlooking the arena stage, poured himself a tall glass of wine and sat down in his throne. Its high back was splayed in a stylistic rendering of a heart, patterned with iron weave filled with purple velvet. The chair emitted a grinding noise as soon as it took the princeps’ weight, the richly appointed seat rising on a concealed hydraulic lift until he sat above the heads of his transhuman guests. The flanking chairs, standard affairs of aluminium alloy caparisoned with the colours of House Callivant, were too small for an armoured transhuman, so Kristos and Alfaran remained standing.

Venerable Galvarro took position beside Chapter Master Alfaran. Exar Sevastian and Magos Qarismi stood with Kristos.

Braavos and Dumaar had remained arena-side with the three claves.

<I can handle ten skitarii,> Tartrak canted in tetchy lingua-form, code-signifiers indicating Ulikar the intended recipient. <Adjust your targeting protocols to the Chapter Master.>

<Compliance.> The Clan Raukaan sergeant’s body shifted imperceptibly towards the right-hand side of the long table.

Emptying his glass in one long swallow, Fabris swirled the empty vessel and peered into the beating rain. A tabarded server hurried between the Iron Hands’ criss-crossing gunsights to pour him another. The princeps calmly relieved him of his ewer and shooed him away. He poured another tall measure and settled back, full glass in one hand, sloshing jug in the other.

‘Praise the Omnissiah for the timeliness of your arrival, Iron Father,’ he said, still watching the rain come down. ‘We could have met this without assistance, but assistance is welcomed nonetheless.’ He sipped at his wine, scowling as if it had soured since hitting the bottom of the glass. ‘Fabris Callivant is no longer a wealthy world. The cost would have been enormous.’ The princeps glanced sideways, but Kristos offered no response. He frowned, uncertainly, glanced at Alfaran who nodded, then downed another mouthful and turned back.

‘The plans for my world’s defence are obviously well advanced and cannot be altered now. Chapter Master Alfaran commands in the void, while Sevastian retains his Dominus status of old and has been granted generalship of all ground and aeronautica forces.’ Jalenghaal diverted a fraction of his attention to the auspex-dark form of the fabricator-locum, threat brackets suddenly spilling over the princeps’ hand as Fabris raised his glass. ‘Overall command, naturally, remains with me.’

‘Naturally,’ Alfaran agreed, unsmiling.

Kristos remained silent. Just the beetling whisper of his armour’s machine cant.

‘Have you nothing to contribute, Iron Father?’ asked Fabris.

Without a single armour section moving, Kristos’ helm rotated on its rings, bringing the currently illuminated lens into bearing with Fabris’ throne. The princeps swallowed. This time without wine.

‘You have not yet sought an opinion.’

Frowning, Fabris moistened his throat. ‘Then I will ask you this – how great a force do you bring with you?’

‘My ironbarque and two strike cruisers. One hundred and fifty Iron Hands plus war machines.’

Fabris clinked the foot of his wineglass against the arm of his throne. ‘Praise be to you, Iron Father. The Omnissiah blesses us all indeed. That is almost as many warriors as Chapter Master Alfaran has already pledged. Tell me, Iron Father, do your warriors favour battle in the void or here on the ground.’

‘We will deploy to the planet.’

‘Excellent. I will have Sevastian liaise with my strategos to draw up a–’

‘You misunderstand. Priority objectives have already been identified and orders assigned. Warriors will be deployed to them as soon as the Alloyed and the Brutus are in range.’

For a moment, Fabris’ lips worked without sound.

Leaving his threat locks to idle over the princeps, Jalenghaal glanced at Kristos.

Even to a warrior as old and hollow as Jalenghaal, there was something terrifying about Kristos. Encased in a bionic exoskeleton of up-armoured Terminator plate, the Iron Father was a monstrous physical presence, but that was not what troubled Jalenghaal, or the machine-spirit with whom he shared a body. Kristos was a noospheric blank, exquisitely constructed for data retention. Passing optics over the Iron Father flooded Jalenghaal’s helmet displays with refracted signals, as if he had directed an auspex beam at a bent mirror. While his systems scrubbed the static, he looked to Sevastian. The fabricator-locum was less perfect. A cursory reading of the magos’ auto-exloads and signal bleed-off confirmed that.

<Kristos and Sevastian are in communication,> he canted.

<Unsurprising,> Tartrak replied.

<Irrelevant,> Ulikar directed them both.

Unsure why, Jalenghaal ignored the Clan Raukaan sergeant and directed his armour’s systems to harvesting Sevastian’s data scraps, setting his cogitator to running them through a series of decryption algorithms. Maybe it was the unexpected simulus training that Kristos had subjected him to, or maybe it was the effect of Stronos’ innate curiosity, but he wanted to know what Kristos and Sevastian had to discuss that was not for Fabris’ or Alfaran’s ears.

A column of red runes racked up along his right optic display. Jalenghaal scowled inwardly. Kristos’ cryptographic lore was too great. He would need to transmit for days for Jalenghaal’s systems to even have a calculable chance of cracking it.

Fabris lubricated his malfunctioning tongue with a long pull of wine.

‘I am sure the Iron Hands are more than willing to coordinate their efforts to best effect,’ suggested Magos Qarismi.

‘I–’

The shudder of an advancing Knight cut Fabris short, the silhouette of something deep maroon and festooned in gold passing through the curtaining rain and into the arena.

VII

The klaxon warbled through the hanging murk and a great cry filled the storehouse. Even arising from a thousand human throats, it was a long way short of human. Rauth felt it enter him, through the pores of his skin, under his fingernails. He breathed it in and felt it swell his lungs. It beat under his breast the way his heart didn’t. He clenched his fists at his sides, the servos in his bionic left squealing. He looked up slowly, struggling to control his rage.

The pit was one of several. When the building had been a working storehouse they would have been part of a subterranean storage area, but removing the floor panels had left a perfect string of gladiatorial arenas.

A heavy man, girdled in copper rings and fizzing with electoos, goaded a pair of cyber-ghouls through a sliding hatch doorway and into the pit. They were immensely muscled, arms braced with combat mounts or simply removed in post-mortem surgeries and replaced altogether with flamers and blades. One was armoured, a breastplate of sheet metal bent over the fleshy left side of its torso, a cuisse of toothed iron over the opposite thigh. The other wore a skullcap pierced with needle electrodes. Sparks of light preceded a reflex grimace and a jerk of movement.

I’m a gene-forged scion of the Iron Hands.

Look at you.

The fighter with the skullcap gave a violent spasm, frothing at the mouth as arcs of electricity coursed through its dead brain, and lurched forwards. The pilot light attached to its right arm ignited a jet of promethium.

Rauth rolled under the spitting arc. Spots landed on his skin and burned. He ignored it. Others sizzled uselessly on his augment casings. He rolled to his knees, slid his hand over the ghoul’s flamer arm and squeezed. The bracing rods attaching the flamer to the corpse limb crumpled. Bent metal severed the fuel lines. Promethium spilled over Rauth’s hand and the ghoul’s arm. Sparks leapt across the ghoul’s helm as fresh commands jerked into its brain. It primed the spring-hammer bolted to its other shoulder as a spark landed on its arm and the whole limb went up in a wumpf of flame.

A casual throw of the wrist and Rauth hurled the burning servitor back into the metal placards that made up the side of the pit. Jolts of bioelectricity spat between the ghoul’s ears. It reset itself to attack again, then exploded, burned meat and metal scraps shooting high into the hooting crowds.

Rauth’s hand was on fire too, he noticed, but he felt neither heat nor pain.

The hardest part is not looking as though I enjoy it. Clenching his burning fist, Rauth circled away from the second, armoured ghoul and looked up.

Still no sign of the adept they hunted in that screen of faces, or of Laana.

Or Yazir.

Why does that bother me?

With a shriek of its diamantite saw, the second ghoul swung for him.

Genhanced reflexes pulled Rauth out of the way at the last minute. The spinning disc-blade whirred over his back and chewed into the floor. Rockrete erupted in a spray. Rauth leapt well clear as the servitor dragged the weapon-tool from the floor. The teeth hadn’t even been marked. It was designed for cutting and shaping the adamantium of Knight armour. It’ll cut through me then. For some reason, that made him grin. The ghoul scythed for him again, and again, diagonal strokes, left, right, left. Rauth ducked and wove ahead of the screaming blade. He threw a knifehand punch that caught the spinning saw on the flat. Sparks jetted from his bionic hand and the ghoul took another gouge from the pit floor.

I was built to face the greatest threats the galaxy knows. Is this all you have?

The armoured cyber-ghoul clanked backwards, chuntering through sewn-up lips as it chewed on the attack algorithms of its doctrinal wafers.

Rauth strode towards it, fists clenched, one on fire. The ghoul issued a moan of muffled and poorly organicised code. It brought down its metal saw like an axe. Rauth caught the wrist housing one-handed, intending to twist the saw aside, but the servitor was stronger than it looked. Better made than the last. The blow knocked him down. He thumped to the ground. The ghoul straddled him. Rauth hissed in anger, straining against the hydraulic power of the construct’s arm as the metal saw hovered a centimetre from his face. The scream it made rippled the flesh of his cheek. The friction heat it put out made the burning promethium on his hand feel like hot water.

Despite the ghoul’s strength, Rauth had a half-metre advantage in reach. He kicked out, a sonorous, buckling clang, but failed to break its armour. He dragged his foot over the ghoul’s breastplate, pushing back, searching for weakness.

His foot lodged in the construct’s neck, and he shoved against it with gritted teeth.

There was a wrenching sound, ligaments stretching, metal tearing from flesh, and the saw arm slowly detached from the ghoul’s shoulder. A stringy matt of dripping wires held it to its body. All strength failed the ghoul’s arm. The saw shrieked down as Rauth rammed it into the floor. The rockrete exploded. The last thing Rauth saw was the construct trying to totter back. He drew his knee to his stomach, then kicked back hard. He felt it connect. The saw ground to a halt as its remaining power was severed. The arm came off in his hand. He batted it away, then bunched his abdominals and flipped from his back onto his feet.

Gasps of approval rained through from the spectator rail above.

Pinching grit from his eyes, Rauth watched the disarmed servitor staggering away. Greasy fluidics drained from its ruined shoulder and splattered over the floor.

The klaxon boomed out a second time and the crowds grew ecstatic.

Rauth looked up as chains sped through rusted hoops, dozens of hatches sliding open from the pit sides to reveal new doors. Praise be. With spasms of electricity and cyborg moans, a fresh horde of ghouls piled into the arena.

VIII

The Knights converged in the centre of the arena stage like two sides of an avalanche. Aftershocks of the collision reverberated through the colosseum grounds, the armourglass shield covering the armoured dais trembling with the force. Twice before Jalenghaal had seen the giant war machines in action. On Moriban he had been part of the Scout clave already deployed to the agri world when the Knights of House Taranis had been unleashed on the genestealer cult infestation there. And later, as part of a larger task force under Iron Captain Draevark, he had helped coordinate the Imperial counter-offensive that, with a contingent of Knights as its spearhead, had culled ninety-five per cent of the population of Junai and all eleven of the Emperor’s Children that had occupied its capital.

But he had never seen them fight each other.

It did not provoke the same visceral response in him that it did the humans. The sensory overload was pleasurable nonetheless. He allowed himself the moment, then directed his full attention back to Princeps Fabris. Autonomous systems had maintained threat locks and client alerts throughout.

He caught Alfaran watching him.

The Chapter Master wore a blank mask of white powder, but Jalenghaal saw a ghoulish flicker of amusement in his dead, kohl-rimmed eyes.

‘Baron Jehar is Keep Warden,’ said Fabris, urgently. He was sitting forward, wine glass hanging from his fingers by the stem as though its taste were ash to him now the exhibition was under way. ‘He is proud and experienced, but Baron Laurentine is a Knight Gallant of estimable skill. Watch him, lords. See how he comports himself in battle. He boasts more engine kills from single combat than any Knight of my House. He has an oft-stated preference for measuring his skill-at-arms against eldar Titans, but he will reap an almighty tally against the crude machines of the greenskin, have no doubt.’

At the mention of the word ‘eldar’ Sevastian twitched.

‘You disagree?’ Alfaran dragged his gaze across to the fabricator-locum, but Jalenghaal could feel something of it linger. As though naked eyes could leave a kill mark.

‘Not at all,’ said Qarismi, his skull features grinning.

Alfaran ignored him. ‘Something darkens your soul, magos.’

Sevastian visibly shrank from the Chapter Master’s unblinking regard, extraneous weapon appendages withdrawing into the core mass.

‘The ork invasion is unexpected,’ said Qarismi. ‘You mentioned the eldar – the fabricator-locum doubtless wonders if there is some malign hand at work in its chosen path. Is that not correct, Sevastian?’

‘It is,’ the magos mumbled.

‘Who can say?’ Alfaran whispered. Jalenghaal heard the sound of snakes in his voice, snakes slithering over human bones. ‘The void is dark and filled with perils. I have hunted the astragatai that devour ships and breathe dark matter and shoal through the gulfs between stars. I have led the Third Company Crusaders in purges of alien hulks. I have waged war with dark eldar corsairs and ork privateers and human pirates, and indeed it is they whom I despise more than any alien for they have been shown the light and turned from it. Who can say what draws this menace to Fabris Callivant and not to another. In an infinite Imperium all things become possible.’

‘Spoken out of ignorance of probabilistic calculus,’ said Kristos, breaking his long silence. ‘And the nature of infinity.’

The ice-sharp gleam of armourglass lenses met the deceptively vacant glaze of hard inhuman eyes. Alfaran’s lips were drawn lines of black paint.

‘Only the God-Emperor is perfect.’

‘No one is perfect,’ said Kristos.

Fabris set down his glass and sighed as though the exchange intruded on his enjoyment of the exhibition.

‘What of the heretek cult that festers in your city?’ said Kristos.

‘My city?’ One eyebrow climbed slowly into the powdered white of Alfaran’s brow. ‘We are many light years from the territory my Chapter is pledged to defend.’

‘You have been here many weeks.’

‘You believe we have been idle?’

Jalenghaal looked from one to the other, trying to determine which was the most inhuman. Fabris cleared his throat loudly and sat back in his high throne, his fleshy face drawn into a countenance that even Jalenghaal could identify as annoyance.

‘It is my city. And it is in hand.’

Alfaran dipped his head graciously. ‘It is, princeps.’

‘Query,’ said Sevastian. Jalenghaal was sensitive only to the most extreme sub-vocal cues, but the fabricator-locum looked suddenly wary. ‘What do you mean?’

Alfaran returned his expression of macabre beatification to the magos. ‘It has been over a century since I have defended a world. But stalwart sons of Dorn we remain. We recall the basic premise of choosing stable ground on which to make our stand.’

Sevastian stole a glance at Qarismi before speaking. ‘Your meaning?’

‘The Hospitallers make three vows upon their acceptance of the Chapter’s gene-seed,’ intoned Venerable Galvarro. The carillon bells mounted across the seneschal’s ornate sarcophagus rang as his vocabulisers turned electrical vibrations into words. ‘To honour the Emperor who is God. To shield the faithful. To bring absolution through death to the heretic, the apostate, the unbeliever and the alien. This is the foundation of our three companies.’

The Chapter Master smiled for the first time.

‘Battle-brothers of the Third Company deliver the last rites to the Frateris Aequalis as we speak.’

IX

Rauth’s fists were a blur of steel and flesh. Parry and block. His limbs felt elongated, drawn with exertion, unresponsive with the speed at which he made them move. His secondary heart thumped a dozen times for every time that one of his fists thumped corpse-flesh, iron or diamantite-tipped points. The stench of rotting flesh and electrical animus was fierce.

Try not to die before we have him, she says.

A pit-ghoul the size of a fully grown ork stabbed at him with an active power driver. He kicked at the tool-arm. The rotating bit shredded the metal of his boot, stripped away flesh and ground on the metatarsal bones. The flood of pain-deadening endorphins made him shudder. The tool-arm swung wide. Rauth shifted his weight onto the savaged foot. It didn’t waver.

She had better be keeping to her side of the plan.

A sharp punch to the throat broke the cyber-ghoul around his knuckles.

Rigor mortis kept the brute standing and Rauth ducked in front. His arms tangled with those of another. A tool-arm drilled messily through the first corpse. Rauth ducked, and it plunged into the chest of the second. Blood slapped Rauth in the face as he threw his shoulder into the second ghoul. The impaling drill carried both ghouls, and the pit-construct toting the drill, to the ground.

Rauth stamped on the drill ghoul’s wrist, until it sputtered and died.

The crowd had fallen oddly quiet, like caged animals expecting to be fed.

He looked around. The hatches in the pit sides were still open, but no more ghouls were coming through. Only one other combatant was still standing. The flow rate of his machine heart fluctuated under the mixed signals from his body.

Fight whatever they send against you, she says. Try not to die, she says.

Easy for her.

He wondered for a moment if he imagined the other warrior’s gallows smile. He smiled back, an unfamiliar surge of warmth spreading through his muscles as he lowered into a fighting stance.

<Good to see you, brother.>

In Rauth’s mind, Khrysaar would always be the neophyte. Over the course of their separate missions here on Fabris Callivant he had developed into a fully matured Iron Hands warrior. He was as big as Rauth now. Bigger even. His bare chest was slabbed with genhanced muscle. His black carapace presented a dark sheen of bioconductive hardening. The numerals 2-0-4 had been stencilled onto his left pectoral muscle. The twisted emblem of the Frateris Aequalis on the right. His eye bionic was a pearlescent white, set within a steel fixture that cut through his face from forehead to cheek to mouth. The other was deliberately dead and level, no hint of recognition. The iron of his left hand was greasy with blood and oil.

A booming report went off somewhere in the storehouse, but such was the general noise level that Rauth didn’t pay it any attention.

<That one with the power driver almost had you,> Khrysaar canted.

<Not even close.>

<If you say so.>

<Careful, brother. Last time we fought one of us lost a hand.>

Khrysaar held up his bionic hand and flexed the fingers. <I am satisfied with the exchange.>

Rauth’s smile sickened into a grimace as he drew up his fists. <What are you waiting for?>

With a sudden snarl of aggression, Khrysaar ran at him. He threw a punch to the face that Rauth blocked, swung a knee to parry Rauth’s, inbound for his groin. You’ve improved. Khrysaar grabbed Rauth’s shoulder with his bionic hand and attempted to push him off balance, but this kind of ultra-close quarters fighting was what the Iron Hands had been built for. Not improved enough. The augmusculature of his left side stiffened as he shifted balance and threw the other Scout’s lock. Khrysaar swayed. Limbs tangled as kicks, punches and feints were thrown in too hard and too fast, and from too close in, to be effectively countered. A punch from Khrysaar hammered into Rauth’s jaw, the same time Rauth’s elbow hit Khrysaar’s throat.

The two Scouts stumbled apart.

Breathing hard, Rauth looked up, annoyed by the lack of appreciation from the crowd.

Not good enough for you?

There was another loud bang, a rattling burst of them. Pulpy detonations sounded amongst the press of bodies and someone, somewhere, started screaming. Bolter fire. A man pitched over the spectator rail with a wail. He hadn’t been hit – a mass-reactive explosion makes a unique mess of the human body – but the instinct of the crowd deemed the cull of a few as fair exchange for the survival of the many. The rest were already a screaming crush, heading for the single alleyside exit.

<Lucky escape for you,> canted Khrysaar.

Rauth snorted. ‘Bolters,’ he said aloud. ‘That can only mean–’

The man who had fallen into the pit moaned, tried to push himself off the rockrete, but both his legs had been broken by the fall and he collapsed into a mewling heap of pain. Not so fun from down here, is it? The mortal stared up at Rauth and Khrysaar, horrified. I imagine we’re bigger up close.

A quiet hum suddenly ran through Rauth’s bones and throbbed beneath his teeth. His guts knotted. I know that sensation. He turned to look up, over his shoulder.

A Space Marine in ash-white armour strode through the narcotic fumes that clung to the spectator parapet like the ghost of a giant. His lenses glowed white with a trace hint of gold. Hospitaller.

A cybermantically animated corpse or weaponised servitor, he could fight. Khrysaar even, he could fight, and kill if he had to. But a fully armed and outfitted warrior of the Adeptus Astartes?

I wouldn’t stand a chance.

The pit-side hatches were still open and Rauth dived into the nearest as the Hospitaller’s bolter roared, rolling like a felled log until the passage became too narrow for his legs and he scraped to a halt, caked in grey dust. Khrysaar. He scrambled up, but there was no sign of his brother in the arena. Explosive rounds burst across the floor where they had been standing. A short-lived cry and a puff of blood from the man with the broken legs.

‘Go!’ yelled Khrysaar.

He had made it to one of hatches on the opposite side of the pit floor. He was hanging back from the mouth of it as explosions chewed the ground and wall plating, waving for Rauth to get away. ‘I’ll find you again at the top.’

‘The day I start listening to you is the day you can beat me in the ring,’ Rauth spat back. He drew back, halfway between a sprinter’s crouch and a belly crawl, and strained his ears.

Rauth could eject a sickle mag and reload in point six seconds. He’d once seen Sergeant Tartrak do it in point four-five. There was a click as the Hospitaller’s trigger hit an empty magazine, and then Rauth exploded forwards.

He cleared the opening, hurdled a dead cyber-ghoul. He’d mentally clocked point four-five seconds when mass-reactive explosions began tearing up the ground around him, shrapnel shredding his greaves. No worse than Tartrak. Rauth launched himself for the tunnel mouth, piling straight into Khrysaar’s chest and bowling them both down. Rauth sprang up without breaking stride, leaving Khrysaar prone as he sprinted down the tunnel. Pain shot up his leg every time his damaged foot hit the ground – damned power driver – but it wasn’t slowing him down yet. Only a matter of time though. The integrity of the boot was the only thing holding it together. It’ll need replacing later.

After about thirty metres the tunnel widened sharply into a conoidal basement chamber. The cyber-ghouls were warehoused there in the weeks and months between tournaments. A single servitor occupied the space, guarding the iron-barred door across from the tunnel. It was not one of the cybermantic constructs but a high-grade weapon servitor, mindslaved to the uncomplicated task of keeping the occasionally unstable cyber-ghouls at bay.

Rauth’s appearance caused its sentry algorithms to initialise.

It lurched forwards on caterpillar tracks wrapped in spiked chains. Power flowed to the arc flail in its right arm, stiffening the previously trailing chain-links and discharging from its spiked head with pealing claps of thunder. The left arm had been replaced with a jury-rigged heavy stubber twin-link. It emitted a clunk-clunk-clunk complaint as it was force-fed on the ammo belts coiled about its waist and shoulder. It regarded Rauth with cog-socketed eyes and a fixed grimace.

It opened up.

Khrysaar ploughed into his back, knocking them both down as the twinned stream of solid lead shot tore into the ground between them.

The heavy stubbers cut out and Rauth staggered back up, wincing at his foot.

<Desist,> the servitor blurted in blank code. Its mind locked for a split second as it struggled to reconcile the unexpectedly complex behaviour of the two Scouts to the countermeasures made available to it by its doctrinal wafers.

With a grinding of gears, it slowly backtracked, turning on the spot to track Rauth. Because I was just born lucky. Muzzle flare lit up its cyborgised rictus, like a corpse on a pyre, and stub-rounds pulverised the wall. There was nowhere to hide. Solid slugs riddled Rauth’s light armour, banged off metal bionics. Several dozen punched straight through his body and splattered the wall behind. He grunted, jigging back against the wall and painting a bloody arc across it as he sank to the ground.

The servitor clattered noisily in for the kill.

Khrysaar grabbed its arm from behind as it raised its arc flail. A sharp yank, a twist, and bone snapped. The arc flail suddenly bled power, the chain-links loosening and thumping the head to the ground. The servitor issued a confused code-burst, pivoting round and round on the spot. Khrysaar jumped onto its motive unit and moved with it, always behind the servitor. He took the unit’s head between both hands and twisted.

There was a moment’s resistance, muscles bulging in the servitor’s neck, then Khrysaar turned its neck half around with a bellow and a splintering of bone.

The Scout jumped down from the servitor’s still-grumbling chassis and staggered back.

‘Can you walk, brother?’

Rauth drew himself to a slouched kneel and grimaced. Breathing was painful, a dozen solid lumps of pain where bullets resisted the simple up-down inhalation of his chest. Air tickled his insides where others had passed straight through.

‘At least they didn’t explode,’ he said through gritted teeth.

‘Not like you to notice a bright side,’ said Khrysaar.

With a shuddering effort and the help of the wall, Rauth got himself up. He was leaking badly. Space Marine physiology could only hold a body together so long. ‘I’ll need an Apothecary.’

‘Did you bring one?’

Rauth nodded.

‘Lucky for us,’ said Khrysaar.

‘He stayed with the shuttle.’

The other Iron Hand smiled grimly.

Rauth shuffled painfully for the door that the servitor had been guarding, pressed himself against it and peered through the iron bars of the viewing hatch. He could hear screams, muted by smoke, rockrete and distance. Smelled burning. The sporadic thud of bolter fire.

‘I don’t suppose you managed to conceal a weapon somewhere?’ asked Khrysaar.

‘No, did you?’

‘No.’

‘Thought not.’ With a preparatory grunt, Rauth shouldered through the door, reducing its reinforced timbers to kindling.

‘Are you going to make it, brother?’ asked Khrysaar, concerned.

‘You know what to do if I can’t.’

Twenty-odd steps later and Rauth was back on the storehouse floor.

His multi-lung wheezed as it accepted great gulps of smoke. Corpses littered the ground, scattered with the detritus they had dropped as they fled. Food cartons. Data-slates. Swipe keys. Staying low, Rauth reached out with one hand and drew what looked like a length of pipe towards him. It had been deliberately melted at one end, reshaped and bound in synthskin to make a handle for a crude walking stick. He tested its weight, and slapped it lightly against his bionic hand. Better than nothing. Crouching low, he looked around. Muzzle flare lit up the smoky storehouse. Eye-lenses gleamed like bolts of las. Rauth estimated four Space Marines in the building. One more then, outside the primary entrance, assuming a conventional combat squad. Answering flashes returned from elsewhere in the building. Bursts of auto-fire. Ribbons of plasma. Lightning jabs of arctricity. As far as Rauth was concerned there were no innocents here, but some were less innocent than others. And it looked like the Frateris Aequalis were fighting back.

‘There has to be a rear access or a window somewhere,’ he muttered. ‘Omnissiah, a skylight even.’

‘There’s a freight access to the back of the building.’ Khrysaar pointed into the smoke, breathing easily but noisily on the toxic fumes. ‘It’s where I was brought in after Laana handed me over.’

Rauth nodded.

‘I should go first,’ said Khrysaar.

Rauth threw him a look. ‘I’m injured, dispensable. I should go first.’

Bent low to the ground, one of them limping, the two Iron Hands ran.

Radium rounds blizzarded from a walkway that passed tangentially overhead. A green afterglow seethed into the smoke as the radium half-lives bled energy. The Hospitaller that the cultists had sought to down shone like a golem of jade as he raised his bolter and shredded the walkway with a tight semi-automatic burst. Honeycombed metal crashed to the ground. Rauth screamed in frustration, skidding on the debris-strewn floor as he tried to drag his damaged foot out of the way. Khrysaar wrapped arms about his waist and dragged him clear.

‘This way! We can go around.’

Rauth coughed. A bad sign. His body was starting to give in. ‘This time… you can… go first.’

With a slow creaking of metal, the roof above the collapsed walkway began to bow. Rainwater trickled in. It was only a matter of time before the entire warehouse came apart. Perhaps that’s the intent? The Hospitallers were practically invincible in their power armour.

A wall loomed out of the murk. The overhead walkway was still just about attached to it, but the bracing bolts were horribly bent and sagged a little further with every squealing second.

‘Come on!’

Khrysaar ducked through the gap between the crippled walkway and the wall. Rauth followed, swatting aside the dangling cables and stays on his length of pipe, and emerged on the far side coughing. He heard a muffled snarl and came up sharply, taking his improvised weapon in both hands. He spun around, and stared into the harsh white curve of a Hospitaller’s gorget ring.

Rauth swung without thinking.

His pipe drove a miniscule crack into the warrior’s ceramite and exploded in his hands. He let what was left of the handle fall with a clatter, palms ringing. Khrysaar was already running away. Good for him. This is no servitor. With a deathly hum the Hospitaller clamped his bolter to his thigh plate, drawing a gladius in the same powered motion. The knife was half a metre of artisan steel, a shortsword in mortal hands, and etched with flowing script that glittered like gold in the occasional glare of his armour’s lights. The crosspiece was made of some dense alien bone. Ork? The pommel had been hand cut from the same material into a likeness of a human skull.

The Hospitaller struck out with it, blindingly fast. Rauth leapt back, arms out, the blade drawing a red line across his chest and digging a nick out of his pectoral bionics. He grabbed the Hospitaller’s knife-hand with his bionic before the Space Marine could readjust, gripping the Hopsitaller’s gorget with the other. With a grind of servos, the Space Marine shook him off and smashed him against the nearest wall.

Rauth coughed, face scrunched in splitting agony as a slug that had been lodged in his lung wall worked its way in and popped into the alveolus. His next in-breath was a liquid rattle. He looked up, hand on his chest. The Hospitaller towered over him like the wrath of the God-Emperor.

A wild scream tore the air. A woman with braided locks stapled to her scalp drove a diamantite spear at the softseals between the Space Marine’s leg and groin. In her wake came a tide of dirty-robed and patch-garbed cultists. Menial labourers with the skin of their arms peeled back and replaced with electrical mesh. Magi with blood seeping from ragged cowls and torn sleeves. Ex-gangers in cobbled together skitarii armour, the twisted Aequalis emblem daubed half and half onto flesh and steel, flickering electoo and dried blood.

For a second, Rauth couldn’t move. Could barely breathe.

He’d seen men and women like this before, he was sure of it. On Thennos? He couldn’t remember the details. Something was stopping him. He could feel an itch in his skull. Like a man trapped in a box, screaming, trying to get out.

‘Brother!’

Khrysaar called to him from the direction that the cultists had just come from.

The Hospitaller delivered the Emperor’s valediction, amplified to ear-splitting volumes by his helmet’s augmitters, as he clubbed men to death with blows from his knees and fists. Rauth saw a man’s arm ripped from his torso, another’s ribcage shattered with a kick that caused bits of spine and organ pulp to erupt from his back.

Rauth wasted no more time in crawling away.

Khrysaar was prying a flechette blaster from the hands of a magos, recently bludgeoned to death and slumped against the arch of a large doorway. Smoke flowed past him, suggestive of an exit somewhere inside. The Scout clutched his borrowed weapon and pointed it in the direction of the current.

‘This is the way.’

Khrysaar led the way now, walking quickly, the sound of breaking bones and prayers for the Emperor’s forgiveness echoing behind them. Winches hung from the ceiling like drowsing bats. Lift-tripods lined an unmarked path, stacks of rusty metal crates blocking off any possibility of hiding between the tripods or taking a wrong path. The smoke thinned as they moved further. A rectangular smudge of light burned feebly in the murk ahead. A thin figure was silhouetted against it.

It was armed.

Khrysaar cursed under his breath and aimed his blaster.

The smoke cleared enough for Rauth to make the figure out. He hesitated a moment, tempted to let his brother fire, then grunted and stayed Khrysaar’s hand.

Laana Valorrn spotted the two scouts a moment later. The smoke was thicker where they stood. Her eyes were feebler. ‘I was about to leave without you,’ she said, her eyes narrowing as she noted Rauth’s hand over Khrysaar’s lowered pistol. She dipped her own. A heap of robed corpses littered the ground around her. They were already beginning to bloat, the most horrific bio-toxins known to the death cults of Medusa accelerating their decay.

Rauth blocked his nose with a finger and blasted blood and snot from the other nostril. ‘I’m glad you… didn’t. There’s something I… wanted… to tell you in… person. Your plan… was… terrible.’

She gave him a knife-wound of a smile. ‘Did you even try not to die?’

Push me, human. Push me once more.

‘Where is Inquisitor Yazir?’ asked Khrysaar, not even out of breath, the wheeze of his genhanced lungs having lessened now that the smoke was clearing.

‘Nearby,’ said Laana.

Rauth frowned; something in the way she said it triggered a faint nudge of suspicion. When was the last time I actually saw Talala Yazir?

‘My brother must see Mohr now,’ said Khrysaar.

‘Soon,’ said Laana, backing away.

‘Now.’

‘Soon. Yazir has the adept.’

A distant explosion pressed a fingerprint of ruddy orange to the splintered armourglass. Jalenghaal thought-selected the infographic to open a data-link to his clave.

<Burr. Report.>

<Stand by,> Burr canted back.

There were no competing sounds as there would have been even on a helmet-to-helmet vox transmission. If not for the positional information relayed to Jalenghaal through the clave’s data-tethers he would never have known that Burr was arena-side, metres away from two duelling Knights.

<Report,> he repeated, peppering his binaric with urgency signifiers.

There was a quarter of a second’s delay. An aeon in electronic discourse. From the trickle of metadata, Jalenghaal could infer his brother’s distraction. <Stand by.>

With a grimace, Jalenghaal thought-selected Lurrgol’s rune.

‘That is my forge-temple,’ said Exar Sevastian.

‘It is salvation,’ said Alfaran.

‘It is a sovereign enclave of the Adeptus Mechanicus!’

‘Your implication being that there are regions of this galaxy where the Emperor’s light cannot reach?’ Sevastian opened his mouth, then quickly shut it again. Alfaran smiled thinly. ‘I had hoped not.’

Sevastian turned to Fabris for support.

The princeps looked with pursed lips from one to the other, weighing up the importance of the Adeptus Mechanicus and the Hospitallers to the coming war. Or more likely Jalenghaal gave Fabris far too much credit and he agonised only over loyalty to a longstanding ally versus his immediate need for an unproven one. Commanding a Knight changed a man. Some said it ennobled him, but that was not the word that Jalenghaal would have used. Chivalry, honour and unreasoning loyalty were not qualities to be admired. A loyal man would not betray a brother to secure a victory. A chivalrous one would not abandon an ally where victory was impossible. The Calculus of Battle could demand either.

With a sigh that sounded as if it had been torn, grudgingly, from his throat, Fabris demurred at last to Chapter Master Alfaran.

‘The self-styled Frateris are a nuisance but a persistent one. Who can say what their mischief might have wrought while our attentions were rightly focused upon the greenskin menace.’

‘They will be dust on the wind before the first greenskin makes planetfall,’ vowed Alfaran.

‘Thanks indeed,’ muttered Sevastian.

‘If any greenskins make planetfall.’ Alfaran’s eyes turned to Kristos.

The Iron Father had not moved or spoken. At least not aloud. His binaric link to Sevastian remained unbroken. But if Jalenghaal did not know better he would have thought Kristos impressed by the Hospitaller’s ruthlessness. Surprised even. And that was a rare insult to inflict upon an Iron Hand. They factored for every detail, planned for every contingency.

How better to militate against the unreliability of instinct or emotion?

‘You have acted as I would have had my warriors been in situ as long as yours,’ he said finally, no trace of reluctance in his vocabulisers. ‘But you will respect the sanctity of the forge sacrarium.’

‘I am inclined to disagree,’ Alfaran murmured. He glanced briefly at Sevastian. ‘We go wherever the rot of men’s souls leads us.’

‘If it should be necessary,’ said Kristos, ‘if there is evidence that a taint lurks within, then I will lead my own warriors to purge it.’

Alfaran’s eyes narrowed as he studied the Iron Father.

On the twenty-hour haul from the system’s Mandeville point, Jalenghaal had inloaded thousands of first-hand witness simuli detailing the Hospitallers’ ability to pierce a mortal’s soul with their gaze, to read their hearts and to know when and how a man will die.

What, if anything, would such a gift reveal of Iron Father Kristos?

‘Interesting,’ the Chapter Master said after a while.

‘I speak from a position of logic,’ said Kristos. ‘The priests of Mars would see the infringement of an Iron Hands clave as a lesser affront. Even you must know that it is unwise to antagonise the Adeptus Mechanicus.’

‘Even I?’

‘If you are so distrustful of my motives then leave some of your own to my command. The tech-priests will be forgiving of a small detachment, provided they are sworn to me.’ Kristos’ optic glow flowed towards the trio of lenses that faced Venerable Galvarro. ‘Your value would be diminished in a void-battle, Ancient.’

Alfaran and his Dreadnought seneschal shared a look, something passing between them that no cryptex wetware could ever crack. ‘The temple is yours, Iron Father,’ said Alfaran, shaking his head slowly. ‘For now, I believe it to be time for the Venerable and me to return to the Shield of the God-Emperor. May He look favourably upon your defence of His realm, princeps.’ He dipped his head to Fabris. Then to Sevastian. ‘Fabricator-locum.’

Jalenghaal, Tartrak and Ulikar clumped aside for them. The floor shook under the Dreadnought’s tread, carillon bells tolling, the dolorous mnemonic immediately casting Jalenghaal’s mind to his simulus memory of the Hospitallers battle-barge.

He shrugged it off with an electrical shiver.

Kristos watched them depart without needing to turn his head. ‘As you wish it, Chapter Master.’

XI

Rauth sat in the dead end of a blind alley, between a lumpy pair of split refuse sacks, and quietly leaked out. Not exactly the way I’d imagined my last moments. The slap of running feet on wet metal interrupted his thoughts, and he wormed deeper into the refuse pile, reaching for the holster of a weapon he wasn’t carrying. The runner splashed past the alley’s mouth and plunged on. Weapons fire popped and burst in the adjoining street. Muffled klaxons cried out into the night.

Rauth forced himself to relax and let his genhanced regenerative process do its work. He tilted his head back. Lukewarm droplets of rain splashed his face, sneaking through the cobweb of conduits and gantries between him and the acidic cloud layer.

How long have I been here? How close are the first ork ships now, I wonder?

For some reason though, his thoughts returned to the Hospitallers.

He had always thought that the Iron Hands – and if he were pushed, their successors – were superior to the warriors of other Chapters. In his core, where it mattered, he still did, but that belief had been challenged today. The Hospitallers’ skills had been sublime. A Chapter he had never even heard of before setting foot on Fabris Callivant, and they had almost proven too much for him and his brother. Something to think about. He frowned to himself, trying to get comfortable. It was impossible that the Hospitaller he’d fought in the storehouse would have been overly troubled by a few dozen mortals. He would have recognised Rauth for what he was, neophyte Adeptus Astartes, and would not have had too much difficulty working out the Chapter he belonged to. It’s not as if there are more than two on Fabris Callivant. Even Laana could work that one out.

He held up his metal hand and watched the rain roll down it.

What would happen when he did?

If it sows distrust between Kristos and the Hospitallers then perhaps that’s to Yazir’s benefit. And mine. He had no loyalty and less affection for his gene-brothers, beyond the immediate imperatives of the mission in hand. His mission was not to save Fabris Callivant, but to claim the Dawnbreak xenotech before Kristos could do the same, and maybe save his Chapter from itself.

He didn’t know the details of what they sought or why. He hadn’t asked. It was enough for him to give Tartrak and Dumaar a bloody nose and, if the emotion could penetrate that far, some embarrassment too.

‘You look awful.’

Rauth snapped his head around. Harsid was crouched behind him, back to the lichen-encrusted tin wall of the cul-de-sac, black armour matted with wet. Rain clad the alabaster smoothness of his face. His eyes were wide, wholly red. Rauth masked his unease with a snarl. There was something about the Death Spectre he could just not bring himself to trust.

‘How did you get behind me like that?’

Harsid’s expression was like a tombstone as he passed Rauth a bolt pistol and a knife.

Rauth slid the blade into the leg of his boot and hugged the pistol one-handed to his chest. ‘Thank you,’ he grunted, making it sound more ambiguous than the words should have allowed.

Soon after, Khrysaar appeared in the alley’s mouth, also clutching a bolt pistol in his right hand and clad now in unmarked Scout carapace. He turned his back and aimed his pistol into the street. Laana came next, leading a miserable-looking adept on the muzzle of her needler. I know you. Mohr shouldered between the group, auto-flensers and scalpel probes flicking from his narthecium gauntlet as he walked to where Rauth lay.

Rauth flinched instinctively, rustling the refuse sacks, but Mohr’s initial observations proved relatively painless.

‘My foot will need replacing,’ said Rauth through gritted teeth. ‘My lung too.’ The last bit of my own respiratory system. For something I’ve never seen, I’ll miss it when it’s gone.

Mohr tried on disapproval before settling into his default frown. ‘The foot, maybe. We will see. I can seal the boot for now, brace it, supplement your body’s natural pain killers. It will keep you moving.’ There was a click as a long ball-tipped probe switched from the Brazen Claw’s narthecium. It wobbled as it neared Rauth’s breast. The metal touched his skin. He felt something inside him pulling. A tearing pain.

‘Aarrgh!’

His flesh tore, a crumpled disc of lead shooting from his chest in a small spurt of blood. It clanged, quivering, to the magnetised probe in Mohr’s gauntlet. A slot flapped open, a nozzle extending from the narthecium’s knuckle, and sprayed the wound with a cold gas that caused the puncture to shrink until the edges curled together.

‘Your lung however will be just fine,’ Mohr announced. ‘And this should stem the bleeding long enough for your body to heal itself. Now.’ The Apothecary looked up. Unlike his captain, Harsid, he was helmeted and the lenses shone like copper coins. ‘Are there any more in you?’

Reluctantly Rauth pointed them out, and Mohr repeated the process of extraction and freeze-treatment until the Apothecary held a collection of five slugs in the palm of his gauntlet.

‘You’ll be weak for a day or so, but you’ll heal.’

What kind of half-hearted practice do you call that? ‘Thank you,’ Rauth said. For sending me back into action at less than full-strength in the lame hope I might survive it to heal in my own time. He took a deep breath, wincing at the excruciating tightness that came well before the lung was full. He spluttered the breath out and grimaced. No, really. Thank you.

‘I am not shy with the knife, neophyte,’ said Mohr, flicking away his tools. ‘But nor do I draw pleasure from the cutting.’

Rauth looked away, thinking back to Dumaar and the cutting table aboard the Broken Hand. Perhaps the Brazen Claw’s way was not the worst he could hope for.

‘Where is Ymir?’ he muttered, unwilling to meet the Apothecary’s gaze.

‘Still on the ship,’ said Mohr.

‘Someone has to be,’ added Harsid.

‘The Hospitallers picked the perfect time to stick their foot into that hornet’s nest.’ Khrysaar pointed to a mushrooming explosion, superimposed by the intervening tangle of guttering, locks and paddled wheels, rising from the general direction of the forge sacrarium. In the surrounding districts, the lights started to blink out.

‘That’s zealots for you,’ said Mohr.

Holding one hand to the tightness in his chest, Rauth sat up. He could smell electricity, the faint bitterness of corruption. He felt the breath of movement that suggested someone else was in the alley with them. Except everyone’s already here. Where before there had been only vacant air, there now stood a feminine figure. Her slender frame was clad in body-contoured armour of vibrant yellows and blues, silvery wires of etheric energy stroking the scalloped plates. Gemstones decorated it. A large, crab-shell power pack lowered her shoulders, made her hunch. But she was still tall. The jewel-studded hilt of a sword stuck out of a fabulously jewelled scabbard. She wore a brace of inhumanly delicate pistols in holsters of yellow flax at her hip.

Yazir.

And then Rauth understood.

He did remember when he had seen her last. A reflection in an armourglass porthole perhaps, glimpsed as his mind had wandered. He looked into the inquisitor’s face. The mask she wore reached inside his skull, terrors that he had forgotten how to feel wriggling to the surface like worms to the rain.

It wasn’t Yazir. There had never been a Yazir. Yazir was a mask.

She wasn’t even female.

His mouth contorted into the frame of a syllable, the starting point for a word, a name he couldn’t quite remember how he knew.

‘Yeldrian.’

‘Would you like to see the device?’ asked Exogenitor Oelur.

Melitan stared at him a moment, gaping, pain throbbing outwards from the implant in her medulla. ‘I–’ She didn’t have enough breath. ‘I–’ Couldn’t think for the formless warning being drawn neuron by neuron across her brain.

‘Do not stroke, Magos Vale,’ Oelur sniffed. ‘Nicco Palpus has wound you so tight. Of course you cannot see it.’

‘O- of course.’ She tried to laugh.

‘That audio glitch is becoming quite distracting.’

‘I will see to it promptly, exogenitor.’

Oelur gestured towards the enormous set of multiply locked containment doors at the far end of the gantry. ‘No one may enter the quarantine chamber. Even the servitors that brought in the technology from Dawnbreak are still inside.’ His primary head turned back towards Melitan with a crunch of gristle. ‘You may relay that to Nicco Palpus.’

‘I will, exogenitor. I will.’

Her breathing was quick and shallow, and it was starting to make her giddy. She turned her back on the containment doors, hoping that would help settle her, and caught a movement from the corner of her eye. It was the skitarii alpha that had caught her when she had stumbled earlier.

He had drawn his plasma pistol and was pointing it at Oelur.

Her eyes widened. Her mouth dropped. She probably had time to react, to do something, probably, but what exactly was she going to do to stop an alpha skitarius? The emission coils burned blue-white, and for a split second Oelur’s primary head and the alpha’s pistol were connected by a string of plasma.

Then the exogenitor’s head exploded into crimson vapour.

Melitan issued a startled mammal sound.

Louard Oelur’s steaming hulk crunched down into his litter and tilted over. His servitor bearers adjusted for the shift in balance but were otherwise unperturbed by their master’s sudden demise.

‘The high will fall,’ said the alpha, his insectile helmet hazing as his pistol vented heat. Around him, the other skitarii were drawing their sidearms. Arc weapons and phosphex pistols. A scattering of taser prods and fist blades.

Chains rattled as the robo-mastiff fought rabidly at the end of its leash, but to Melitan’s rising horror it was not the skitarii maniple that had offended its spirit. Its keeper regarded Melitan with bovine eyes, muscular arms shaking with the robo-mastiff’s efforts to get free, a mouth overspilling with audio-sounders and wiring stretching into a cruel smile.

The gantry stab-lumens winked out, then the illuminations within the subject cages, then one by one the runebanks fell offline. Everything went black. Infocytes continued to tap on lifeless keys. Melitan’s heart hammered in her breast.

Only the twinned glow of the alpha’s optics pierced the gloom.

‘The Dawnbreak Technologies are an idea,’ the voice behind them said. ‘The very essence of that which cannot be contained. Would you like to see it?’

And she screamed.

Stronos wished he had teeth to clench. The pain of having the roof of his skull cut away was tremendous, and in spite of all his neural safeguards and endorphin pain blockers he almost blacked out on more than one occasion. But it was over now. With a soft crack, like the hatching of a monstrous egg, Magos Phi removed the top of his head. Her attendant was already there, slurping at the membranous dura mater with a suction hose. While they had been waiting on Stronos’ servitor, Phi had introduced him as Jeil. As if current proximity to his higher functions made them close. Most of his attention however was on the blood swirling away from him through the net of transparent tubing. Jeil’s hose sucked around the rim of his brain pan. A curious sensation, but a blessedly painless one.

His eye rolled to the side, his bionic, of course, fixed to a wide-angled but forward view of the ceiling. His equerry-servitor stood against the shelved wall, watching with wide-eyed placidity as the magi cut. Stronos found its presence reassuring nevertheless.

‘I am going to make a single longitudinal incision into the meninges,’ said Phi, out of view behind the head-end of the operating slab. ‘Once that is removed I will insert probes into your frontal and parietal lobes in preparation for implantation. Then I will draw your brain fully from the skull in order to access the dorsal regions of the temporal lobe and the cerebellum. I have never performed the procedure on a conscious subject before. I cannot say what you will experience.’

Stronos could feel his hearts beating, nervous, out of sync, his cold skin was clammy. It was not pain he feared, but the surrendering of control. Absolute control. He was allowing the agent of an unfriendly power into his brain.

Mars was not even, he reminded himself, technically a part of the Imperium at all.

He glanced again to his servitor.

He would review the entire procedure as soon it was finished. Once he returned to Medusa he would have Lydriik and Apothecary Haas go through it with him frame by frame.

‘Are you waiting on my permission?’ he grunted.

Phi chuckled. ‘I told you I have never done this with a conscious subject. I am enjoying the novelty.’

‘Get on with it, magos.’

There was a hum as the magos instructor’s arc scalpel moved in to cut. There was no physical sensation of contact, but light flashed across his eyes as the blade cut in. Both eyes. As if, to the manifold synaptic connections of his mind, he were still the pure organic being that had received Ferrus’ gift one and a half centuries before. ‘How far from our Father’s likeness we have both fallen,’ said Tubriik Ares, his voice resonating from within the light. ‘You do not save a soul by cutting it away.’

And then the light was gone.

Stronos blinked, vision returning, but leaving his hearts floundering.

He looked around. Everything was dark. The arc scalpel had lost power and it was not alone. All the little sounds of life support and power generation that had maintained life in Scholam NL-7 were gone. In its place, silence.

‘What the–?’ Phi began, before Jeil stabbed her through the back of the head with his suction hose.

She spasmed in the menial’s embrace. Stronos pulled furiously on his restraints as chunks of the magos’ brain matter and the occasional lump of something metallic disappeared noisily into the evacuation tubes. He concentrated all his augmented power on freeing just one arm. The slab rattled beneath him, but there was no breaking the clamps.

‘The high will fall,’ sang Jeil’s voice from behind him. ‘The low will rise. That which is within shall be without.’ Stronos shivered under the phantom sensation of fingers running down the ridged lobes of his brain. ‘The Sapphire King will rejoice.’

>>> INFORMATIONAL >> THE KRISTOS HETERODOXY

There are one thousand and fourteen distinct forms of spoken Medusan, in addition to three hundred and seventy-two discontinued variations, and there is no direct translation for the word ‘chance.’ This was why the majority of Medusans at the time, technologically advanced yet culturally stunted, saw the arrival of Ferrus Manus as an omen, a glimpse into the schema.

It is worthy of remembrance that his descent in fact burned the sky and broke Mount Karaashi, previously Medusa’s highest peak – the Omnissiah could not have delivered the tenth primarch in more spectacular fashion had He presented him with His own hand.

For this reason too did his gene-sons receive the death of their primarch with more stoicism than those who suffered a similar loss, at least outwardly. They raged, they sought to lay blame, and for the ten thousand years that followed they indulged their bitterness, but on some level they had known.

It was meant to be.

CHAPTER TEN

‘I do not fear you, Space Marine! In the eyes of the true Omnissiah we are all equal.’

– Anon.

I

Stronos clenched the muscles still present in his jaw and pulled. Servos shuddered as reserve power flooded his arms. The clamps over his wrists began to creak. He closed his eye and pulled, a roar, tinny and hollow, emerging from his mouth like a blast from a horn. But the clamps had been built to restrain his kind, an adamantite alloy manufactured to the same process used in the production of Terminator plate, and they would not give.

Chuckling, Jeil circled the operating slab. Without a functioning spirit in control of the base the darkness was absolute, and Stronos’ occulobe organ could barely scavenge enough stray photons to pick out the moving outline. He blinked his augmetic to the far-red, the switch conjuring a humanoid wraith thing of dull crimson, haloed in purple, spots of yellow over the nose and mouth. An electoo burned like a branding iron against the side of the mortal’s face.

‘Your rage is empty, Iron Hand.’

‘You know nothing.’

‘I knew all that your kind would have me know. Now I know better. You are desolate. And I am free.’

Stronos tried to rise off the table. Failed. The clamp dug into his forehead.

‘Would you like to know what an Iron Hand really feels?’

Jeil responded with tuneless laughter. He leaned over the foot-end of the slab, hands to the sides as though caressing a perfect machine. ‘Oh, I would. Yes I would.’

‘Stand when you address an Iron Father,’ said Stronos.

Jeil looked surprised, but grinned as he did as he was bidden, a yellow gash opening the red of his face.

His eyes bulged suddenly, bright discs widening as his feet left the ground.

It was as if he levitated. The mortal made a choking sound, kicking out with his legs, pulling at the room-temperature darkness locked around the redness of his throat.

Stronos let the power to his arms dissipate.

With a last gasp of air, Jeil expired.

His legs gave one final twitch.

‘Target deceased,’ intoned the servitor, cold-bodied and utterly invisible in the dark.

As tenth sergeant of Clan Garrsak, Stronos had held the ultimate power, of override, over each of the nine battle-brothers of his clave. Exercising remote operation of an equerry-servitor that had been mindslaved specifically to him did not compare.

He closed his eye and for a moment his perspective was split into two.

He saw the reclusiam. A yellow sphere directly above where the overhead lume source had left its heat. Purpling handprints on book bindings or on bits of equipment where Jeil or Magos Phi had touched them. The cooling carcass of Jeil himself, hung from the servitor’s patiently unmoving fist. At the same time, his closed eye of flesh saw himself through the servitor’s optics. A dark giant of crude flesh and hard metal, scalped, smeared with blood, illuminated by the faint glow of his armour’s own energy sources. He saw his own brain. It pulsated within the shelled wreckage of his cranium like an alien parasite. The sight of flesh made the servitor ape his grimace.

First things first.

‘Compliance,’ the servitor muttered, responding to the neural imperative.

And Stronos felt a hand that wasn’t his own move towards the clamps.

II

Stronos lay a finger along the dent in his vambraces. He pulled fists. The right gauntlet betrayed a point one-second delay in responsiveness, the left a six-kilogram reduction in grip strength. He released his fists with a grunt of annoyance. Between his duel with Barras and trying to break out of the chirurgical clamps, his armour’s spirit was in dire need of ministration. He glanced up before he could think about it, offering a wordless prayer to the scholam’s spirit and the Omnissiah of which it was a part. It would need to wait a little longer yet.

He walked around the operating slab. The equerry-servitor moved automatically out of his way. It still held Jeil’s corpse in its hand, lacking any direct instruction to do otherwise. Stronos had yet to decide on the most fitting manner of disposal. He dismissed his still-smouldering anger and pressed it down hard.

Revenge was illogical. Regardless of whether the object was living or dead.

‘You are all my sons and the fires of the forge burn as hot in your hearts as they do in mine,’ warned the Scriptorum of Iron. ‘Chain them, master them, and you shall wield a deadly weapon, but allow them to rule you and you shall be lost.’

The runebank at the head of the slab was still giving off a faint heat.

The body of Magos Instructor Yuriel Phi was slumped beside it. Spots of blood lay around her like scattered flowers. She was still warm, but her eyes were dark. Looking more closely, Stronos realised that it was because her eyes were not there anymore, sucked into her skull by the vacuum hose still sticking from the back of her head. Stronos removed it, set it lightly on the ground, and put his hand on her small, still body. He had wanted to like her.

Strange how much less complicated that wish became now that she was dead.

‘The Motive Force abandons you, magos. But the Omnissiah neither creates nor destroys, He merely rebuilds anew.’ He bowed his head. The Chaplaincy had always been his true calling. He withdrew his hand and rose to his feet.

He saw what he had come looking for.

The top of his head, pale skin and thickened transhuman bone, sat upturned in an organ tray, cleaned and glistening. Iron Hands were cold, in all aspects, and little of Stronos’ meagre body heat lingered on the bone. Only what Phi and her bone saw had inflicted on it. He picked it up in both hands, as if preparing to crown a grisly monarch, taking a moment to correct its orientation before slotting it back onto his skull. He grimaced. Bone did not move comfortably over bone; the cap did not slip, but friction was currently the only force holding his head together. He looked around for something to secure it.

His gaze fixed on Jeil’s manual driver. A smudge of colour brushed the tip, fading handprints forming a phantom grip about the handle. With a reluctant sigh he picked it up between thumb and forefinger, using it to loosen a screw from the clamp hinges on the operating slab.

The screw was ten centimetres long, one centimetre wide, and with a thick thread.

With only a brief hesitation he positioned it at an angle to his head. The thread pinched his skin as the tip of the driver slotted into the head of the screw. He winced as he began slowly to torque his wrist.

This was going to hurt.

III

Fifteen minutes later, Stronos staggered from the reclusiam, boots clumping loudly in the dark on the corridor’s metal flooring. Blood dribbled down his face, clotting factors gluing gauntlet ceramite to his pate where animal illogic maintained it would slide off if he did not hold it down. The seventeen points of agony spaced around the roof of his skull said otherwise. He held out a hand to the wall and forced himself to concentrate. Power was out across the base, so whatever was happening it clearly went beyond one deranged menial. Even the scholam spirit had been banished to its host cores. Its absence explained the failure of the emergency lumens, the utter, utter quiet. Stronos wondered how long it would take before the air became unbreathable. He could function without oxygen for hours, but if Jeil’s surviving confederates could not physically restore the oxygen pumps then this would be a conveniently self-terminating rebellion.

‘Thecian, report,’ he murmured, manually depressing the transmission switch on the inside of his gorget ring. Static washed back. ‘Sigart, report.’ He tried to raise Barras and Baraquiel to similar effect.

He turned around.

The servitor waited in the doorway.

With far-red having proven inadequate to the conditions, Stronos had reverted to the standard spectrum and activated suit lights. A flood of multi-source lighting drenched his equerry’s every slough and bolt and threw long, multi-pronged shadows from each.

‘Return to my cell and retrieve my helmet. Kill anything you find there that is not Thecian.’

‘Compliance.’

‘If you should find my brother there then tell him I am heading to Operations.’

‘Compliance.’

The servitor started off down the corridor with a lurching stride. In the dark, it would also serve the additional purpose of drawing any hostility before it found Stronos. He was not sentimental. It was a long way to Operations, and without the scholam spirit any sealed door might hold him for hours. He deactivated his lights and followed.

The servitor made it to a ‘T’ in the corridor without confrontation.

It turned left.

A flurry of las-bolts seared across its back, flesh cooking off, lighting up the shooter in the right-hand corridor like an exploding lumen.

Coming in behind the servitor Stronos was as good as invisible, but even over the sizzle and crack of las-fire the shooter would have heard the scrape of his armour against the walls from a kilometre off. Las-bolts stubbed against his armour as the attacker abruptly switched targets, a brief spate of shots before the mortal ducked into a recessed service crawlway.

Half a metre too broad to follow, Stronos lunged in with an arm, drawing back sharply as a torrent of max-power las bracketed the narrow opening and scorched the red brickwork facing. Laughter echoed from inside the passage. Stronos scowled.

The las-burn that had glanced his outstretched hand was more insulting than injurious.

A fresh crackle of las-fire made him turn.

The servitor was still going, trudging down the left branch, soaking up fire, making it another few strides before it lost too much musculoskeletal function to keep moving. It staggered onto one knee, still striving to complete its last imperative. Stronos shouldered it aside, ripping sparks from the wall’s metal banding as he forced his bulk down the corridor.

The robed human at the other end of the corridor hurriedly ejected his pistol’s charge cell and slotted in another. He thumbed the power dial to maximum.

‘I do not fear you, Space Marine!’ he shrilled, face contorted by an ecstasy of hate. ‘In the eyes of the true Omnissiah we are all equal.’ Las-fire splashed off Stronos’ armour in a furious tirade, draining the charge in the seconds it took for realisation to dawn that men were not made equal.

Stronos was an arm’s length away, face a horror mask of brute iron, las-scatter and friction sparks running from his battered plate as if he had stepped straight off the anvil of his making.

Backing off, the man punched a control panel in the wall behind him and dived bodily through as the hatch it operated slid open.

His epiphany came too late.

Stronos caught him by the foot and dragged him back into the main corridor. The human tried to hold on to the joins in the floor plates by his fingernails, but he would have done no worse trying to resist being pulled along by a Leman Russ.

Stronos held him upside down by the ankle.

‘You were sworn to the scholam’s spirit. What have you done here?’

The man laughed hysterically. ‘You have no idea! I would sooner–’

Stronos let go, the man dropping a metre to land hard on his shoulder.

‘You give up so easily. This is what comes of ir–’

The word became a scream as Stronos’ boot crushed his spine, burst his heart, went through his ribs and shoulder blades and ground it all to meal with the pulp of his lungs. The heretek’s fingers twitched for a dozen seconds of oxygen-starved existence as the clump of Stronos’ bloodied boot disappeared down the corridor.

IV

With a whine of over-stressed servos, Stronos forced the doors apart.

The corridors had widened not long after he had left Magos Phi’s living areas, but it had still taken him seven hours and forty-three minutes to cross the scholam and reach Operations. His skin was cooked and blackened. His exposed bionics looked little better, the same charcoal-black as his maltreated plate. Armed insurgents – and as per his initial judgement, the uprising seemed widespread amongst the menial population – started appearing with rebreather kits and crimson greatcoats, but they never stopped appearing. Although they did not let him get close again. Whether the same group of attackers had been harrying him all the way or he had been ploughing through fresh pockets of menial insurgency as he went, he had no idea.

He pushed himself between the doors and stumbled through. They bit behind him with a resounding metal clang. Muted gunfire pattered on the other side. He turned and hammered his fist into the airtight vertical seam, buckling it.

Nothing less than a Space Marine would be opening that door now.

Operations had only one way in or out. For once, Stronos would have the layout of the scholam working to his advantage.

A single shot rang out.

Stronos’ armour was already pitted like a rogue asteroid and it took another hit as the auto-round ricocheted off and thumped into the metal wall panelling. Taking one step onto the companionway that ran the outer tier of control stations, he tore the outer cover from the nearest runebank housing – logically enough, it was door control – and hurled it in the same unbroken motion. There were no sparks. The unit did not suffer.

The moulded plastek sheet moaned as it cut the air, ripped open the shooter’s neck and thudded into the wall.

The decapitated heretek loosed off one more shot as his body wobbled to the decking.

Operations had a rotating staff of twenty-five, but it looked as though about three times that complement were crammed into the server pits and companionways now, transforming it into something between a house of defilement and a narcotic squat. Bedding rolls and blankets filled the crosswalks. Clothing fluttered from handrails in the thermals coming off the arc heaters and crank-operated carbon dioxide splitters. Spare oxygen canisters were stacked up like sandbags.

Stronos realised that he had no idea how many hundreds, or thousands, of mortal menials worked below his notice in the service of Scholam NL-7, but he had the sense that he was going to be unpleasantly surprised.

They had, at least, been taught to keep their heads down.

Shrugging off only the occasional snapshot, Stronos worked his way around the upper companionway, one eye on the operations cradle that hung over the chamber like a husk. Whatever was being done to the scholam, he would be able to see it from there. Provided he could revive its systems.

Passing through the grilled metal walls and dulled lights of the radiation manifold, the station that Baraquiel had occupied scant days before, he noticed bodies tangled up in the bedding. They scattered before his approach, clutching blankets. Stronos felt an almost overpowering urge to go after them. There was a perversion to the lather of their bionics, the oiliness of their bare flesh, that bypassed his systems entirely and riled his flesh. He suppressed it with the most shuddering of efforts, almost relieved by the distraction of bullets riddling his side.

He held up his iron hand, deflecting most of the fire aimed for his face, then picked up an oxygen canister and hurled it like a grenade. Its seal broke, flattening an autopistol-wielding woman with an eruption of compressed gas as it corkscrewed off through the tight confines of the medial tier pits.

Stronos’ weary cogitator compiled a morbidity estimate and he gave a grunt of satisfaction.

He was about to move on, work his way around the gangway to the oversight cradle, when he felt something.

It was a brush against his mind, and it pulled him up short, staring at the blank terminals of the radiation manifold, ignoring the furious pot-shots blasting the Martian redbrick behind him. It was a noosphere. A haunting of residual charge in the runebank, the lingering potential between cathode and anode. The whisper of a territorial snarl wormed between Stronos’ thoughts, but it was shorn of authority, something that a great beast would growl in its slumber.

Stronos felt the abortive twitch of a smile.

Scholam NL-7 yet lived. He could work with that.

A colossal bang against the doors forced his attention back to the physical realm.

He looked up just as a fist-sized bulge of metal grew from the blast doors, effectively reversing Stronos’ crude attempt at bracing it. Half-finished analytics spilled hurriedly over his screens.

Nothing human was capable of that.

The doors shrieked apart a second time, and Stronos clenched his fists and turned to meet whatever it was trying to force its way through. He caught a glimpse of bone-and-brown power armour between the widening doors and reflexively loosened his fists.

Barras.

His unhelmed face riven by a murderous frown, the Knight of Dorn held the doors open as first Sigart and then Baraquiel ran through. The two Space Marines were still in their liveried smocks and aspirant tabards, but had at least managed to pick up weapons. Despite Operations offering barely enough space to wield a gladius, Baraquiel charged down the spinal walkway wielding a two-handed power sword the way a warship wielded a ramming prow. Sigart braced his feet and brought a full-size bolter to rest against the upper companionway rail. Omnissiah alone knew where he had got it as they had all had to surrender any ranged weapons upon their secondment to Mars. Another legacy of the Horus Heresy. The Black Templar opened fire with a roar, shredding cold machinery and living flesh with equal abandon.

Thecian was last in.

The Exsanguinator’s face and the front of his robes were bloody, as if he had just plunged his face into a pail of fresh offal. He was unarmed and unarmoured, yet leapt two-footed over the companionway rail onto the medial bank, punched his fist through a panicked heretek’s chest, then caught another by the hair and bit the back of her head off while she screamed. Stronos watched, aghast, as Thecian hurled the woman off him, sinking his teeth into his own wrist to visibly regain some kind of control. He turned, his fine features made haggard by bloodlust and self-hatred, to look up at Stronos.

Stronos did not ask.

They all had their daemons to fight.

Barras eased the doors shut behind him, but they stopped at about a fist’s width apart and refused to close a millimetre further. The Knight of Dorn swore, freeing his combat blade.

‘What is out there?’ Stronos asked.

Barras glanced over his shoulder, performing a double-take that might have been comical under other circumstances. ‘You will have to learn how to use cover.’

‘I am inclined to agree,’ said Stronos, gingerly touching one of the screws in his skull.

Barras grunted, backing away from the door and settling into a ready stance. Stronos had learned to respect that look. ‘We fought through a cohort of a skitarii vanguards to get here. They have brought in some heavy firepower on Magos Phi’s watch. At least one Kataphron unit that Baraquiel saw.’

There was a break in the explosive cacophony as Sigart reluctantly paused to reload.

The operations hub looked like the victim of a mauling. Baraquiel was searching through the wreckage for something unspoiled enough to clean his enormous blade on, settling finally for scraping it on the handrail. Thecian meanwhile had backed into a dead-end pit and was hunched over his bleeding arm, digging his fingernails into the bite wound to keep the hypercoagulants in his blood from clotting. Stronos could see numerous old scars up and down the Exsanguinator’s arm. He was muttering an incantation that was, presumably, intended to be calming, breaking every so often to headbutt the wall.

If these were the control methods that Thecian had been extolling to him, then Stronos was unimpressed.

‘Kardan.’

Stronos looked up as Barras tossed him a spare knife, and caught it from the air by the grip.

‘You’re useless with your fists.’

Stronos snorted, surprised to find that he was actually amused by that. An uncertain sensation of warmth prickled through his insides.

‘This is Thennos all over again,’ he muttered.

‘What happened on Thennos?’ said Barras.

‘Rebellion.’ Stronos shook his head. ‘Unimportant. Except that it will take vastly more than the strength of one Chapter to purge Mars unless we can put a stop to it here.’

‘Purge Mars? Are you not overreacting, just a little?’

‘I have seen this before.’ Stronos looked around, lingering on the mortal dead. ‘It starts low, amongst the menial population, before spreading to corrupt others. I do not know how, but as I say I have witnessed the consequences of inaction.’

‘Then what is our course, brother?’

‘Find the source of the contagion and destroy it.’

‘It?’

Stronos nodded, but said nothing.

‘Where?’ Barras grunted.

Stronos furrowed his brow, but behind it he felt an answer form.

It was unusual for a machine-spirit, particularly one as jealous as Scholam NL-7, to reach out of its own volition, but he felt a tingle as it laced its system tethers with his and whispered its valediction. The pulsed binaric translated to a word.

Just one.

<Primus.>

CHAPTER ELEVEN

‘She Who Thirsts and Ayoashar’Azyr are the masters of this dance, but it is the Laughing God who shapes their tune, for it is a fine tragedy indeed.’

– Fall

I

The alpha skitarius dragged Melitan along the walkway by the wrist. She kicked out with her feet, trying to find purchase on the runebanks as they slid by her, succeeding only in knocking over a few stools. The cyborgised veteran condensed more strength into his one arm than she could summon from her entire body.

And if she could get away from him – what then?

She felt herself succumbing to panic. Her heart was beating faster, thoughts spilling through her mind at a frenetic pace. She was numbly aware of herself pleading with the dumb Legio Cybernetica muscle-brute plodding on behind her, even as she wriggled like a maggot under a vivisector’s needle. With another pointless, piercing scream, she dug her heels into the grated flooring, yanked on her trapped hand and scrabbled along the floor for something to hold on to. Her fingers tore in her desperation, leaving bloody trails on the metal behind her. The blinking lens lights of the binary infocytes in the underslung data cradles blurred beneath her, stars in the heartbeat before warp translation. The lights were not especially bright, but they stung her eyes, setting off a pulsing migraine that made her gasp, killing her own efforts to escape as she slapped her palm to her forehead.

‘Why do you struggle?’ The alpha sounded genuinely perplexed. ‘We have been waiting decades for this moment. The chance to abase ourselves before the Sapphire King.’

Clutching her face in one hand, Melitan could only scream. It was an inhuman sound that came out of her, something ripped out of her, torn, mangled by a shrill binaric register that had the skitarii legionaries twitching in discomfort. Her eyes filled with racing numerals, as if her brain had triggered a purge and restart. Her mouth widened, but no sound emerged now but a strangled whine.

‘What is this?’

The alpha tightened his grip on her wrist and pushed the still-warm emitter of his plasma pistol to the roof of her head. The other skitarii backed off, warily, drawing weapons from sidearm holsters and covering their alpha.

Thrashing on the end of its chain, the robo-mastiff snarled and snapped at Melitan, salivary lubricant flying from its heavy jaws, its noospheric olfactors picking up the forced rewiring of Melitan’s higher processes and driving it wild.

Surrendering to the mastiff’s instincts, the keeper let some slack into the chain.

Pain erupted from somewhere deep in Melitan’s brain, repealing the mastiff’s paralysis codes and burning a command phrase into the ashes of her insular cortex.

‘Deimos!’

Motive Force abandoned the robo-mastiff even as it exploded forwards. It was as if the verbal override had doused its battery packs and severed every wire in its make-up, its sub-intelligence wiped clean before its dead body had crashed to the floor.

The keeper looked up from the junk metal shackled to her arms and at Melitan. It was difficult to express horror around so much suturing and functional addenda, but that was what she did.

‘What did you do?’ asked the alpha. Instead of shooting Melitan in the head, which is what she would have done in his place.

Omnissiah, when had she started to think like that – like an Iron Hand?

‘Androktasiai,’ she hissed. ‘One-one-zero-zero-zero-one-one. Execute.’

The primary data-tether, responsible for gating all inload/exload to the skitarius’ neural functions, went into sudden overload. Sparks sprayed from his temple, triggering a cascade eruption from the warriors of his cohort as the invasive kill algorithm jumped between their linked systems. They spasmed and jerked as their neural wetware melted into their grey matter, nonsense binaric screaming from their helmet grilles. The alpha clattered to the derrick and steamed. The rest of the cohort were not long behind. The acrid stink of melted plastek rose off their torched husks.

Only the Legio Cybernetica slave was still upright.

For all her obvious enhancement, her bionics were singularly, brutally functional. Her purpose did not require the same degree of interconnectedness as the legionaries. The muscle-brute tried to back away, but the spirit-flensed junk weight of the robo-mastiff was too great even for her. She went nowhere.

The unpackaging sub-personality in Melitan’s medulla nudged the somatic nerves in her face to produce a predatory smile.

She bent to scoop up the alpha’s plasma pistol. She had never held one before, and yet somehow she knew every aspect of its arcana. She aimed it at the keeper’s head, nudging the power slider towards minimum. So soon after Oelur’s execution, she didn’t want to risk overheating it.

She blinked uncertainly. Her vision doubled and wavered, and for a moment it had looked like someone else’s hand around the pistol. Or someone else’s eyes seeing it.

Could she do this? Could she end a life, just like that? Was she–?

She squeezed the trigger.

Warmth splattered her face, and she realised that the chamber was beginning to spin. She was prepared enough to throw out her arms before legs buckled from under her.

II

Melitan came to with a splitting headache. She had no idea how long she’d been out, but it couldn’t have been long because the infocytes were still beetling about nervously in their underfloor spaces rather than rolling her off the side of the gantry.

‘I must be getting used to passing out,’ she muttered to herself as she got hands under her to push herself into an upright sit.

The chamber turned around her as though she had become the centre of the galaxy, and she cradled her head in her hands with a groan. The distant rumour of screams and gunfire was barely audible through the reinforced walls of the observation level, but it felt as if it were going to sonicate her skull to powder. Nevertheless, the sound was oddly reassuring. Pleasing even.

The Dawnbreak Technology may have spread its corruption beyond the containment chamber, but the cellular operation of Zero Tier had contained it to a degree. Someone fought back.

She blinked until the gantry stopped spinning, and found herself looking down into the fractured optics of the alpha skitarius. She had done that.

‘Is that you in there, Palpus?’ she whispered to the pain in her head.

It was still there, but wasn’t getting any worse. She wished she could say whether that was good or bad.

‘What’s my favourite colour?’ she asked herself. ‘Red.’ She frowned. That probably didn’t prove anything amongst the Martian faithful. ‘What were my parent’s names?’ Her automatic use of the word ‘were’ gave her a moment’s pause, but she answered promptly. ‘Greta and Hayden Yolanis. We lived in the Laurentine Baronial Habs,’ she added, in case of doubt.

Satisfied that she was still her, she mustered the wherewithal to stand.

The power to the overhead lumens and the rune displays was down, but it was not, she belatedly noticed, entirely dark. A bitty grey sheen of low-grade illumination was coming off the cells that dangled over either side of the gantry. It was not an active light, but a luminescent strip of some kind, reminiscent of the radium tags she had used to paint on munitions canisters as a child-aspirant on Fabris Callivant.

She turned in the direction of the outer doors, far, far, out of sight at the far end of the gantry, and considered her situation.

As soon as the corrupted skitarii had the base secured, and perhaps not even as long as that, every last one of them would be looking to get into this chamber and past the containment doors behind her. How long would it take a skitarii maniple to shift those two doors without main power? She dismissed the speculation. It was the wrong question. They had severed power to the base, so they presumably had the means of reviving it when it was in their interest to do so. Impressed by her own perspicacity, she turned her unexpected clarity of thought to what that meant for her. Should she stay, try to defend the Dawnbreak Technology for as long as it took for help to arrive, or use what little time she had to effect an escape? She shook her head. Again, the wrong question. This was Noctis Labyrinth Faculty Primus. No help was going to simply arrive. She was going to have to get out there and bring it back herself.

That was one problem solved, but it still left the biggest challenge in front of her.

How?

Almost before she had turned her full focus on that question, the solution came to her, the proprietary codes and facility schema she would need to enact it filing into her mind. She felt herself giggle. This was real knowledge, real power. It was what she had groped towards all her life and now it was hers.

She turned to look down the faintly luminous rail of cells.

She could do it. But she couldn’t do it alone.

III

The Harlequin’s eyes were larger than a human’s, deeper, in some spiritual, non-dimensional sense. The ghosting smile on her face hadn’t moved since Melitan had atomised the two infocytes who had tried to keep her from the cell.

‘What is your name?’

The authority behind her own voice surprised her. It seemed to catch the alien unawares too, for one achingly perfect eyebrow lifted.

Melitan nodded, satisfied. ‘Good. You hear me at least.’

‘I hear you, Magos Vale,’ the Harlequin answered, addressing Melitan by the name that Oelur had spoken in front of her. There was a peculiar cadence to her speech, as though her mind formulated it in verse rather than in prose. ‘I hear the laughter of Cegorach. The stage is diminished, the prizes cheaper, but still we perform his favourite dance.’

Melitan frowned, suspecting the eldar was mad. Whatever the oddities of the eldar psychology, she had been captive a long time. But again, some understanding that she was only dimly aware of possessing assured her that this was not so. This was simply the eldar’s peculiar manner of employing their spoken language – through cultural reference and idiopathic metaphor.

‘So what is your name?’

The alien laughed with mock gaiety. It was a performance, as the years of silence that preceded it had been a performance too. ‘Know me by the part I play. Call me Fall. And I shall name thee Pride.’

Melitan gritted her teeth. ‘Do you wish to be free or not?’

‘None of us are free. Only Pride would think so.’

‘Let’s try something less rhetorical. If I let you out of there, will you kill me or help me?’

The Harlequin simply smiled.

‘If you can give one straight answer, make it this one.’ Melitan held on to the safety rail and leaned over until her mechadendrite was almost touching the front glass of the cell. ‘Has the Dawnbreak device affected you?’

Fall’s laughter this time was unscripted, as though the question had been unexpected. ‘Of course,’ the eldar answered. Her sing-song voice took on a smoky quality as she mirrored Melitan’s posture and leaned forwards. ‘Is your imagination too infertile to understand what the eldar of the final Acts would turn their brilliance to?’ She laughed again. ‘But its effect on me is different. Your minds are different. Lesser. More subject to change. She Who Thirsts and Ayoashar’Azyr are the masters of this dance, but it is the Laughing God who shapes their tune, for it is a fine tragedy indeed.’

‘Wait,’ said Melitan, struggling to master her frustrations at the eldar’s riddling tongue. ‘What?’

Fall spread her hands dramatically. ‘Cegorach adores tragedy. It is the dance of Thiraea and Pyr. Desire steals the Wise from Reason, and brings only Death upon that which Desire pursues. I have danced that dance many times and played many of its parts. Always we hope otherwise, but always it ends the same way, and always do I dance it anew on different stages.’

Melitan was about to ask the eldar what she meant, but she knew. Deep down, she knew. This was why she – why Palpus – had wanted the technology contained, even as he had been forced to bow to Kristos’ order that it be preserved. It had been blighted by Chaos at birth. And now, because of Kristos and his ambitions, it had inveigled itself into the destiny of the Iron Hands. And of Melitan Yolanis.

‘I need to get out of here. I need to deliver word and bring help.’ Fiddling with the grip of her plasma pistol, Melitan agonised. Could she trust the eldar? Did she have even the remotest of chances of getting out of Zero Tier without her?

‘I’m going to release you,’ she said, reluctantly.

The Harlequin shrugged, as if Melitan’s decision had never been in doubt.

Turning from the cell, Melitan removed the smouldering form of the infocyte from the controlling runebank with a shove of her foot. There was no life to the unit, but to one with a full grasp of the Motive Force that was no bar. She understood as if it were obvious.

Like an Imperial Saint laying-on hands to a wounded soldier, she placed her palms to the console. She felt a tingle in her fingers as the subtle galvanism of skin on plastek breathed new life into the system. Mumbling and whirring the cogitator came online, reviving the infopane in turn with a sputter of greenish light. She held her breath, awed by the miracle she performed even as she performed it. One hand on the console to preserve the circuit, she manually keyed in the cryptex phrase. It was long and fiendishly complex. Exogenitor Oelur had envisaged no circumstance in which these cells were ever meant to be opened. But just because a possibility could not be envisaged did not mean that it did not exist, and the Voice of Mars had made certain to receive inload of the codes.

Comprehending the acceptable margins of ignorance was what separated the aspirant from the master.

The front wall of the eldar’s cell detached silently and dropped into the abyss. Melitan watched it fall, watched it disappear, and kept watching until she heard it shatter. She let out the wheeze she hadn’t realised she was still holding in, and looked up.

The eldar hadn’t moved at all.

Melitan pointed her pistol at her. ‘Get dressed. We’re leaving.’

CHAPTER TWELVE

‘The worst kept secret on Medusa, since the uprising. The entire Iron Council knows there is something there.’

– Iron Father Verrox

I

‘I knew you would come crawling. Sooner or later.’

Iron Father Verrox stood framed by the access hatch of the rumbling Land Behemoth Ruination, lit from behind like an angel of annihilation despatched by the Emperor of Mankind. Although divinities and miracles were seldom proximate to the Clan Vurgaan Iron Father. Lydriik tramped up the ramp, head bowed, battered by the wind, his Rhino lost to the dust and howl of the ever-moving Behemoth.

Verrox glowered over the high rim of his gorget, a glint of tooth showing.

‘I thought it would be sooner.’

‘It is good to see you too,’ said Lydriik, dust screaming past his visor.

Verrox went proudly unhelmed. Long grey hair clad in iron ringlets whipped about him like the medusae of Grekan myth, banging on the hull plating and on the vast breadth of his Indomitus plate. The armour hung heavily on him, like a pelt, the rattling war-harness scored in old Juuket signifying the worlds he had laid to waste and the xeno races he had consigned to extinction. Totems and trophies of the same hung from battered lengths of chain. There were shell casings, traitor insignia, the mummified anatomies of alien monstrosities bested in single combat, all of them butting and twirling as the Tactical Dreadnought suit breathed. Lydriik’s armour had once been similarly adorned, before it and he had been ushered into Clan Borrgos.

The Iron Father grinned, simian lips drawing over serried rows of chain-driven teeth. ‘The Vurgaan are the lions of Medusa. The Borrgos are jackals. I knew you would never be content on the Broken Hand.’

Lydriik nodded, without acknowledging the truth of what the Iron Father said. Verrox was terrifying, somehow embodying both the epitome and the antithesis of what it was to be an Iron Hand, but there was something intoxicating about him as well. Like hovering one’s finger over a mega-weapon’s trigger switch.

‘I have a favour to call in, old friend.’

‘Of course you do.’

With that, the Iron Father turned ponderously and strode inside.

The temperature soared by about fifty degrees as the wind fell away and the hatch was sealed. Lydriik removed his helmet, sweating in spite of his environment seals, and wiped sweat from his brow. The air aboard Ruination hovered around freezing, but everything was relative. It was a peculiarity of Iron Hands physiology that favoured the cold. Securing his helmet to the magnetic lock-strip that ran alongside his pistol holster, he followed after the Iron Father.

A hundred years he had been of the Vurgaan clan, in the wake of a battlefield initiation from Verrox himself on the feudal world of Battakkan. That century had been spent entirely on campaign, battling to remove the tau and their proxies from worlds across the Western Veil. This was his first time aboard the mobile monastery of his former clan.

Rusted weapons had been nailed to the bulkheads, so many they overlapped and made a wall of blades. The blood of those slain on them still tinted the blades. Red, black, green, pink. The air was coloured, like the cathedra of a Cardinal World, and it smelled of murder. Suits of armour stood sentinel over door hatches. Not Space Marine power armour for that was sacred, but trophies of a thousand campaigns. Ork mega armour. Eldar ghost armour. Understandably, given the clan’s recent campaigns, tau combat armour and battlesuits were particularly abundant. Everything rattled with the Behemoth’s unstoppable forward motion. The beat of blades on shields. The thud of boots on alien worlds. It was like walking through a mortuary ship, peering across the canyon of death, and seeing a gun line of the alien and the heretic.

Ruination could not wage war as her bellicose spirit yearned, confined to the Sthenelus System, and so the Vurgaan appeased her by bringing their wars to her.

Lydriik found that he was salivating, his remembrancer organ thrilling to the sour raiment of industrial-scale death.

‘I have not heard from you since we parted ways over Thennos,’ he said, eager to break the silence.

‘And I was surprised to hear from you now,’ Verrox grunted. His enormous shoulders rolled with his stride. ‘Garrison duty is a misery all must share, but the knowledge that Fell or Kristos will suffer equally after me does not make the burden any lighter. I would almost welcome a Thirteenth Black Crusade.’

Lydriik was an infrequently observant adherent to the Iron Creed, but he found himself miming the blessed cog. It had been almost three hundred years, his memories dimmed by childhood and the changes wrought on his psychology in the centuries since, but he remembered the Twelfth. It had been an active time for the Black Ships.

From the slow growl of his teeth, Verrox remembered it differently.

‘What of Stronos?’ asked Lydriik. ‘You must sit regularly with the Iron Council.’

‘Only when the monotony becomes too great and I must find a different breed of boredom to alleviate it.’

‘The Kristosian Question continues to be asked?’

‘Five hundred years I have endured, give or take. I was there on Keziah. I led the Vurgaan through the Gothic War. I have tasted the flesh of Devram Korda, fought every race that you have heard of and butchered more that exist no longer. I will be damned if I will let the Kristosian Conclave be the death of me.’

Lydriik could not help but chuckle.

He did miss the Vurgaan clan. They were aggressive, virile, brutal most certainly, but unashamedly so. They did not dress up their excesses with logic or reason. They were what they were, the same unflinching barbarians that the primarch had made them.

‘The sooner Stronos returns to my side of the argument the better.’

‘It takes thirty years to train a Techmarine,’ said Lydriik. ‘You think the question will still be unanswered when he returns?’

The Iron Father emitted a growling sigh. ‘There are Medusans as yet unborn who will claim seats on the Iron Council before this is resolved.’

Lydriik frowned. He had only observed the workings of the Iron Council from the outside, but he could well believe it.

‘Iron Father Stronos,’ Verrox muttered, shaking his clinking mane. ‘That he should climb so high in just a hundred years. Draevark was not pleased, you know. Not at all pleased.’ He chuckled in amusement. ‘If you had told me on Battakkan that the neophyte who had just destroyed my Thunderfire cannon would stand beside me in the Eye of Medusa, I would have torn open your throat and eaten your progenoids.’ His teeth whined. ‘Spare future generations from such flights of illogic.’

Lydriik could never tell when Verrox was attempting to be light-hearted.

‘I… always had him for the Chaplaincy,’ he said.

‘As did I. He thought too much.’

‘But he wanted to rule.’

‘Just what the Iron Council needs. Another thinker.’ Verrox stopped to punch an input code into a door hatch. It hissed open, releasing an unpleasant alchemical stink.

Lydriik took the opportunity to glance under the Iron Father’s shoulder.

The cell was relatively large, as befitted the title of Iron Father, and space was far from premium on a vehicle of Ruination’s scale. At most a hundred warriors called the fortress home, and there would be few mortal servants, discounting those that toiled at the bequest of the Adeptus Mechanicus in the enginarium subdecks. There was no pallet, no workbench, just a single rune display and a door that presumably led to an arming chamber. Only Verrox’s size made it feel cramped.

The Iron Father stepped inside and clumped slowly around. ‘Are you going to tell me what this is about or must I beat it from you?’

‘It is because of Thennos that I am here. I have been tracking the xenotechnology that Kristos and the Voice of Mars had attempted to conceal there.’

‘The worst-kept secret on Medusa, since the uprising,’ said Verrox. ‘The entire Iron Council knows there is something there.’

‘Was,’ Lydriik corrected.

He went on to tell of his efforts to track the technology down, culminating in his encounter with the Voice of Mars in the Meduson archives. The involvement of Harsid and Yeldrian, a child of the Raven and an alien, he thought best to keep to himself.

He drew a heavy siliceous key from the equipment pouch at his hip and showed it to Verrox.

‘Obtaining the information was not difficult, but it will take weeks to analyse it. Months. I am likely to be sent to Manga Unine to join my brothers in a day.’

‘Being out here on Ruination should buy you a day or two.’

Lydriik nodded. ‘But that’s not why I came.’

‘No?’

‘I have not the resources,’ said Lydriik. ‘And I have not the skills.’ He held up the key for Verrox. ‘And I have not the time.’

The Iron Father’s eyes focused on the key. Like all forty-one of the Chapter’s Iron Fathers Verrox had been a Techmarine, and even if he had never actively served in that capacity he had been inducted into the same circle of mysteries.

‘Palpus allowed you to walk free with that?’ he said.

‘They are highly compressed, compiled in some archival dialect I do not understand, and that is just the ones I can convince to open. He knows there is no way I can analyse a fraction of it before I am forced to leave Medusa.’

Verrox snorted. ‘Tech-priests believe the Omnissiah blessed them alone with an organ in their skulls.’ He opened an enormous hand and Lydriik gladly handed the key over. The Iron Father turned his back and inserted the key into the slot by his rune display.

‘It contains only the file descriptors,’ Lydriik explained. ‘The hard data is all aboard my Rhino. They were too bulky to bring over.’

Verrox was no longer listening.

He turned the key, the runebank emitting a chewing sound as it crunched on the data, numeric sequences piling into the graphical display. He punched in a complex string of commands and the numbers began to sort, scattering left and right over the wide screen. The sequences began to arrange themselves, aggregating into growing clumps either side of the midline. The Iron Father followed the sorting data as though watching a saint at work.

Sensing that he would get nothing further from Verrox now, Lydriik put his hand on his helmet and began to back out of the cell. ‘Leave a message with the Librarius when you have something. On my return from Manga Unine, I promise I will find the technology.’

‘It’s there.’

‘What?’ Lydriik stopped.

‘There.’ Verrox pointed to the tiny collection of sequences that made up the left-side clump. Data was still pouring out of Lydriik’s key and into the cogitator, but most of it was coming down on the right. Whatever that meant. The Iron Father snarled over his pauldron. ‘Never trust a priest that doesn’t believe you can think for yourself.’

‘What have you just done?’ asked Lydriik.

‘What do you know about file descriptors?’

Lydriik shrugged. ‘A run of numbers that leads into the body data. It’s meaningless, but each one is a unique sequence, so the archivists use them for sorting and archiving.’

Verrox nodded, mouth unzipping like a mountain lyger that had found a carcass outside its cave. ‘It’s random, but collate a number together, a few hundred thousand, and suddenly, not so random.’ He gestured to the rune display. ‘Particularly if they were all uploaded from the same location.’

‘You mean you…?’

Verrox jabbed a finger towards the larger data clump, the sudden motion causing servos to whir. ‘Meduson.’ Then he indicated the various scattered sequences that had resisted his sorting algorithm. ‘Off-world, presumably.’

Lydriik stepped in closer, the rune display painting his upturned face green, and pointed at the smaller group of sequences. ‘So where is that?’

>>> HISTORICAL > THE BATTLE FOR FABRIS CALLIVANT, 212414.M41

Thirty-nine hours after their warp shadow first fell across the system’s edge, the orks’ ramshackle armada arrived at Fabris Callivant.

The dispersal pattern of the greenskin ships has been submitted to every rite of analysis known to the prognosticae and no coherence has ever been ascribed to their assault. They came at the planet and its aegis rings like a wave, a stampede, capital junks boosting ahead of their escorts in a headlong charge. Their massive prows were antlered wedges of scrap plating. Crude welding maligned the impression of horns, fangs and tusks, the paintwork a garish clash of colours presenting the Callivantine lines-of-battle with an onrushing horde of xenos deities and fungoid beasts.

The Imperial and Basilikon Astra fleets, by contrast, had barely moved in weeks. Fire protocols had been disseminated down the command chains days in advance of this moment. Every commander, from the lightest reconditioned frigate in Battlefleet Callivant to the Shield of the God-Emperor, knew exactly their place in the line.

The ‘honour’ of taking the first shot fell to the Mars-class battle cruiser Golden Ratio.

Grand Admiral Tigra Gorch had served out a working retirement in this Naval backwater with some dignity, if not distinction, enough to earn a marriage contract into House Callivant for his services. An insignificant niece, but females one hundred and two years a man’s junior with ties to a pre-Imperial dynasty were not, apparently, betrothed every day.

The blast of the battle cruiser’s nova cannon ignited a second sun, three hundred thousand kilometres above the planet’s surface.

The explosive power of twenty plasma warheads detonated under the front of the ork wave. Viewing oculi and auspectoriae of the heaviest battle cruisers would have bleached to white, while on lighter ships with less-significant shielding, sensoria units would have fizzled and popped. Living out its life cycle at relativistic speeds, the newborn star was entering its death stages even as the Golden Ratio’s drive stacks fired off to counter the cannon’s recoil. Logisters aboard squadron command ships tallied kills [LOST TO RECORD]. Aboard the Golden Ratio herself, pride of Battlefleet Callivant, the Grand Admiral’s chief of staff delivered a toast [ALSO, ALAS, LOST TO RECORD] to Gorch and his vessel’s honour.

But the battle was only just beginning.

CHAPTER THIRTEEN

‘No man of the Imperium shall fall to enemy hands. Not while a Hospitaller yet wields a blade.’

– Venerable Galvarro

I

The Venerable Augustin Sangreal Galvarro found the death of his enemies an uplifting experience. It brought him closer to the God-Emperor. An experience as near to true warmth as could penetrate the uterine tank where his limbless torso swam in cyborganic suspension. There were times, of course, when such pleasure had to be forgone, for the Emperor possessed enemies in multitude undeserving of the absolution that death by a crusader’s hand conferred. Not for the ork the mercy of his fists. No. Only a pitiless execution by laser lance or cyclonic warhead would do for such beasts.

The carillon bells mounted atop his sarcophagus jingled as the Shield of the God-Emperor shook. A purplish ripple of bruising filled the forward oculus as the starboard voids shunted the force of incoming ordnance into the warp. The gene-eunuchs in the tiered choirs about the bridge delivered a strident hymn of abjuration.

‘Permission to retaliate, Venerable?’

The Shield of the God-Emperor’s mortal shipmaster bowed at his feet. She was an elderly woman who had taken the crusade name Grace. Her double-breasted white jacket had scripture sewn into the cuffs and lapel, a golden cummerbund in the form of the aquila worn over the waist of a pair of brocade trousers.

‘Let the candles be lit.’

‘By your word, Venerable.’

She turned sharply and gave the command, one thousand serfs of the chapel illuminatus igniting tapers and setting them to black candles. The ritually prepared wicks fizzed before settling into a bright, white light.

‘Let us be the bearers of His light,’ Galvarro intoned.

‘By your example, Venerable.’ A nod to another crewman who deftly manipulated the dials and sliders of his runebank. Scores of powerful hull-mounted luminators beamed into space, hand-crafted filters in the form of martial saints and aquilae branding the foul alien that passed across their light.

‘The light in Him is the light in us. Let it burn the dark.’

‘By His will, Venerable.’

‘Ave Imperator.’

‘Ave Imperator!’

The thousands-strong bridge crew, choristers, serfs, armsmen, all delivered a thunderous rejoinder that would have been audible to Him on Terra. Galvarro shivered as the phantom sensation of metal, and its embossing scripture, brushed his shoulder. In his rapture, he had attempted to raise his hands, his mortal remains slapping feebly against the wall of his tomb.

Another shudder ran though the ship, a squeal as the impact force dispersed through her internal skeleton.

‘Now, Venerable?’

‘Now.’

Shipmaster Grace let out a breath, as though relieved, though clearly that could not be, for time given unto the Emperor was time given joyously.

‘Status of the Shield of the God-Emperor,’ he demanded.

‘Shield coverage of all quadrants. Engines on standby burn. Weapons loaded and charged, targeting matrices aligned.’

‘Alfaran?’

‘The Chapter Master and the Third stand ready on the embarkation decks.’

‘Good. And the fleet?’

‘Formation is holding. Battlefleet Callivant and the Basilikon Astra are at station keeping around the Darkward star fort and the orbital gun rigs. They’ve yet to engage. Battlefleets Dimmamar, Trojan and Warfleet Obscurus bear the brunt so far, but it won’t be long now.’

‘Our cousins in black?’

‘The Iron Hands…’ She pulled at her elaborate jacket cuffs. ‘I don’t know.’

Galvarro focused his vid-captors back onto the forward oculus. A wandering vertical of capture distortion marred his vision, but he had long ago made his peace with it, for through its signature oscillations did the Emperor, in His guise as the Omnissiah, impart foreknowledge upon this instrument of Man’s deliverance.

If he could but learn how to descry His words.

‘We are all His soldiers,’ he said.

‘As you bid, Venerable.’

‘Venerable!’ The call came from another serf who spun his chair to face his mortal superior and the Dreadnought that towered over her. ‘Urgent hail from the Euphrates.’ The Tyrant-class cruiser was a squadron flagship of Battlefleet Dimmamar, stationed in line-of-battle a few hundred kilometres forward of the Shield of the God-Emperor. The serf covered his headset with his hands, relaying the transmission even as it came in. ‘They’ve been boarded. The orks have taken a dozen decks and have the bridge besieged. They plead immediate assistance.’

‘And by the grace of the Golden Throne shall they receive it,’ said Galvarro. ‘Shipmaster.’

‘Your order, Venerable?’

‘Destroy the Euphrates.’

‘Yes, Venerable.’

Without pausing to question, the shipmaster relayed the order, watching as Galvarro watched, as the embattled cruiser disintegrated under the Shield of the God-Emperor’s firepower. She mouthed a prayer for forgiveness, though forgiveness was not what the Emperor provided.

‘Set course for where the xenos are thickest, and signal all Hospitallers vessels to match our heading.’

‘It will be so.’

‘No man of the Imperium shall fall to enemy hands,’ Galvarro announced, feeling the glorious mass of the Shield of the God-Emperor as it slowly began to move. ‘Not while a Hospitaller yet wields a blade.’

II

<Correct bearing,> canted the magos calculi. <X plus thirteen degrees, Z minus forty degrees.> No sooner had the Alloyed come within a million kilometres of the Omnipotence than Qarismi’s commands had manifested in his brain like a suspicious thought. The interlink signal was sharper, over a greater range, than conventional vox. Draevark remembered having once been fascinated by how the technology worked. Another distant mortal desire rusted unto nothing.

‘Compliance,’ said Draevark.

Sparks gouted from a tactical cogitator as Draevark relayed the magos’ coordinates to his crew. The bridge lit up momentarily. A battlefield illuminated by skyburst flares. Bodies lay in bloody pools, half buried under the emesis of overloaded bridge tech. Electricity crawled sporadically over crumpled bits of decking. Bent pipes spewed gas. Smoke hung heavy in the air, but the worst of the fires had been extinguished.

Most of his crew was already dead.

‘Three ork kroozers maintaining pursuit,’ one of them shouted.

A sudden impact hurled the unfortunate crewman from his standing station and onto a bracing spur that had fallen from the ceiling. The serf gasped, eyes rolling, as three metres of plasteel exploded from his chest. Astrogation erupted over the current helmsman.

Draevark watched the mortal writhe, faintly disgusted by the pink colour of the smoke he gave off as he burned and by the sweet stench of roasting meat.

‘Will no one enter my coordinates?’ he demanded, directing a spasm of power through his gauntlet.

A serf with a crude, three-pronged hook for a hand and blistered red skin who looked as though he had shaved in acid took the station.

‘Aye, lord.’

The thought that Kristos might have deliberately held the Alloyed to the grinder focused his anger like a bolter to the back of the head. The Iron Father had used the Garrsak and Borrgos Clan ships rather than his own to delay the ork armada, and he suspected he knew why: lest Draevark and Tartrak combine their strength to demand their Apothecaries’ return by force. Even together, the Alloyed and the Brutus were no match for the Omnipotence. Certainly not now.

Draevark clenched his fist, the talons of his deactivated lightning claw grinding against one another as he pictured the monstrous Raukaan Clan ironbarque in his mind.

Once he returned to Clan Garrsak’s Commandment, then Kristos could expect a reckoning.

A sprawling, mental tri-D of the battle zone filled Draevark’s thoughts, a square of broken glass crammed into an ovoid vessel. It was as crabby and broken as the rest of the Alloyed’s punished systems, more often than not a boiling mess of neuralgia and static. He compartmentalised the discomfort, surrendering a portion of himself to suffer while the rest of his mind focused on drawing meaning from the static.

‘Our new heading takes us away from the planet,’ he muttered to himself.

<You will still arrive eleven minutes before the orks,> Qarismi replied.

Time enough for his small force to deploy to Sevastian’s forge sacrarium and dig in.

‘It is an intercept course for the Shield of the God-Emperor.’

<That is not your concern.>

Draevark glowered at nothing. He was running out of brain space in which to box away his anger.

‘Is Kristos with you? I want to speak with him.’

<He is engaged elsewhere. You may speak with me.>

A feedback growl reverberated from his grille. ‘Ask him if he thinks I would be unaware that Clave Jalenghaal and the Three also approaches the Shield of the God-Emperor from the planetary side. I am iron captain of Clan Garrsak. He forgets who he is dealing with.’

<Sheath your claws, iron captain.>

Draevark turned his head and noticed that his armour’s spirit had indeed ignited the talons of his left gauntlet. They were bathed in a humming electrostatic field, tongues of energy licking from claw to claw.

<You are wondering if I am watching you. I am not. I do not need to see you to know your every action before you do. Rest assured that I never ‘forget who I am dealing with’.>

Draevark blink-selected the ‘deactivate’ rune in his helmet displays, his claw hanging suddenly heavy as it powered down. ‘What will you have us do once we reach the Hospitallers barge?’

<That also is not your concern. Yet.>

‘I will not ram a ship twice my displacement for Kristos.’

<You worry too much, iron captain.> The code formulation of the cant signified amusement. <The reach of the Voice of Mars is long. The Shield of the God-Emperor is going to begin losing momentum ninety seconds from now. Plus or minus three-quarters of a second.>

III

The cascade electrical failure that took out the Shield of the God-Emperor’s monstrous drive stacks was visually unspectacular, but undeniably effective. Drive plates that had, up until that point, been burning like the surface of the sun fell dark, bleeding off waste heat as black smoke into the void as the battle-barge’s entire aft section drifted lazily to port. Inertia continued to push the bulk of the warship on its prior heading, but it went port-side on now, slowly sacrificing forward velocity to its turn. Jalenghaal watched the vessel list in near real time, tracking it through the viewing block in the crowded troop bay of the Three.

‘Convenient,’ said Lurrgol. It was the most sensible word to have passed the warrior’s vocabuliser in days, and the rest of the clave forgot the abrupt disablement of the Hospitallers flagship for a moment to look at their brother. ‘Well, it is,’ he muttered, turning his helmeted gaze back to the block.

It was indeed convenient.

With the battle-barge’s titanic drives at full burn, the Three would never have caught up until she began her deceleration to combat speeds, by which time she would have been crawling with ork fightas and turret duels.

A sudden shift in bearing knocked the harnessed Iron Hands’ heads together. Borrg swore, his bald head already beginning to colour where it had slammed into Strontius’ helmet.

‘Wear your primarch-be-damned helmet,’ growled Thorrn.

The neophyte threw the veteran a grin that the purpling of his forehead only made more savage.

Shutting himself off from the aggression that Borrg was unconsciously dumping onto the clave interlink, toxic even split ten ways, Jalenghaal opened a link to the pilot servitor. Information rushed from source to sink, and for a fraction of a nanosecond he was the pilot servitor. He was laid out on the cockpit slab, bound with cable leeches, eyeless gaze forward as dogfighting Fury Interceptors and ork fighta-bommers jinked across the armourglass screen. Flak bloomed around the gunship, corresponding to every bump and buffet that the troop bay felt. The Shield of the God-Emperor was a monolith of toppled white stone directly ahead, growing larger and larger with every moment of travel.

In the time it took an electron to race the twenty metres between Jalenghaal’s restraint harness and the cockpit, and come back again, he had the situation update he sought.

‘Trouble?’ asked Burr.

‘No.’

The Iron Hand did not need any additional detail than that.

Another blast knocked them all about in their harnesses.

‘I wish I knew what we were doing here,’ Borrg complained. ‘I thought things would be different after leaving Clan Dorrvok.’

Lurrgol snorted, but said nothing.

He was clearly entering one of his more lucid phases.

<Analysis of behavioural patterns indicate a ninety-five per cent probability that Chapter Master Mirkal Alfaran will abandon the Shield of the God-Emperor along with a sizeable contingent of his warriors in order to lead his Chapter’s offensive. Most likely aboard the Inviolate Zeal, though the confidence margins disbar me from supposing a figure of likelihood.>

Jalenghaal looked instinctively up, though the voice was inside his head.

The primary command tethers installed into every new recruit to Clan Garrsak’s suit-brain interface were generally reserved for high-level clan functions. Jalenghaal wondered where the magos calculi obtained the authorities to access them.

<Galvarro will be on the bridge,> said Qarismi.

Jalenghaal summoned the simulus file he had inloaded from Iron Father Kristos. The keel of most Imperial warships was laid down to standard template patterns and, paintwork and serial numbers aside, they were essentially identical. Internally however, the character of the Adeptus Astartes Chapters showed through. The Shield of the God-Emperor’s bridge was vast, with a crew of thousands, and distant sons though they were, the Hospitallers were still scions of Dorn – their command centre would be a fortress. He quadruple-checked the melta bombs and haywire grenades studding the magnetic bandolier that crossed his chest plastron. It was a long way from his standard loadout.

<Resistance will be heavy.>

‘Compliance.’

<You will enter by embarkation deck gamma, starboard. I have calculated that position to be furthest from the anarchic element of xenos interference.>

‘How will we bypass their shields?’

<They will lower them for you. Draevark will see to that.>

Jalenghaal processed that for a moment.

<Are you not going to ask me what Kristos wants with the Venerable Galvarro?>

Thinking back to the sight of Kristos’ first sergeant, Telarrch, laid out on the bridge of the Isha’s Spear under a stasis field, Jalenghaal knew exactly the reason.

He replied, ‘No.’

<Do you have any ambition to the captaincy of Clan Garrsak, tenth sergeant?>

‘I have no ambition.’

He thought he heard a chuckle resonating between his ears. <As it should be.>

Deception did not come naturally to an Iron Hand, at least not to this one, tenth sergeant of the Second Clan Company. It was contrary to the order of the schema. Despite Jalenghaal’s best efforts to codewall himself against Borrg’s febrile mood, some of his disquiet must have filtered through the interlink, because Lurrgol suddenly stirred.

‘Never dilute your strength by fighting alongside another,’ he said, sounding oddly wistful. ‘You alone are strong.’

‘When did you begin reciting the Scriptorum of Iron?’ asked Burr.

Lurrgol turned to Jalenghaal, zero recognition in his helmet lenses as he gave his sergeant a nod. ‘When Stronos became our sergeant.’

IV

Macro impacts blistered the Alloyed’s port shields. The effect of dumping all that kinetic energy onto the immaterium was a kaleidoscope of hellishly distorted colours that infected the oculus screen, and a piercing whine that Draevark dialled out but which clearly discomforted the mortal serfs enormously. They knew better than to let it impair their work.

From what Draevark could prise from the Alloyed’s intransigent tri-D mapping, the battle for Fabris Callivant’s orbit went well.

The orks had bloodied their foreheads on Battlefleet Dimmamar, but its ships held firm, only now disengaging under covering fire from the heavier line ships of Warfleet Obscurus. Fresh vessels of Battlefleet Trojan and a few Basilikon Astra squadrons plugged the gaps. Their bulk and firepower alone were enough to keep anything larger than an attack ship breaking through, while a handful of incision boarding actions from the newly returned Hospitallers warships granted some relief from the pressure.

The great bulwark against the ork wave, however, was the Darkward star fort.

The Dark Age bastion was inviolate. Its shields were massive. Even the Omnipotence would struggle to strip a single layer from its interplex void arrays before its graviton pulsars and conversion lancers carved the great ironbarque apart. In that wonderfully predictable way the orks had when presented with an alpha opponent, the greenskins were unleashing everything they possessed at it. Bloated battleships and ram-fronted destroyers alike disintegrated on its defences. Battlefleet Callivant had little to do but snuff out the occasional orphan fighta and hurl torpedo salvo after salvo into the mad scrum of ships.

Draevark looked up as a sudden vibration rattled the debris over his bridge. He felt a mild disorientation, as if his weight had been temporarily drawn to an angle ever so slightly off one hundred and eighty degrees, before the Alloyed’s artificial gravitics compensated for the effect.

‘Report.’

‘I think you need to see this yourself, lord,’ said the hook-fisted serf who Draevark was devoting serious thought to naming shipmaster.

Draevark’s mindlink to the Alloyed’s auspectoriae was becoming lagged by battle damage and her spirit’s upset, so he clumped towards the serf’s station. He interpreted the gravimetric parabola and its accompanying runescreed in the time it would have taken a mortal to blink an eye. In the few, jealously guarded places where he remained warm, he ran cold.

‘Patch through to starboard viewers and magnify.’

The oculus dissolved into static, fizzing back to life after an inordinate number of seconds to present an image stolen from the ship’s starboard vid-captors. A single shape dominated the oval screen. A dark lump. Pinprick lights lit it, and at first Draevark assumed them to be guide lights for attack craft, but then he noticed the magnification bar at the base of the display and readjusted the scale of his thinking. They were explosions, every one an ork warship being rammed and carelessly obliterated as the object drove through the heart of the ork fleet towards Trojan’s line of battle.

‘How far away is it?’

‘Blood of Manus, it’s an asteroid,’ said the shocked serf.

Draevark regarded the man a moment, then smashed his face into the runebank, demolishing the mortal’s skull and spraying its contents down the sloping console and over the iron captain’s greaves.

‘How far away is it?’ he repeated

A temporary silence held sway over the bridge before another serf found the personal courage to step forwards.

He was young. Most were young, the mortality rate aboard Draevark’s ship saw to that, but he looked barely nineteen or twenty. An old burn whorled one side of his face. The eye was pinched shut and blind. His plain black uniform was tattered and several exterior rods held his arm to his shoulder, but otherwise he was remarkably whole for an adult Medusan.

‘Fifteen minutes from Battlefleet Trojan,’ he said.

‘Can it be destroyed?’

The new shipmaster-elect consulted a dozen stations, taking reports from his former peers. ‘It’s fifteen hundred kilometres across at its narrowest point, massing at almost five trillion tonnes.’

Draevark grunted. It was about the same size as Thennos, Medusa’s rad-bitten ninth planet. Even the Golden Ratio’s nova cannon would not make a dent in that.

‘It’s heading straight for the Darkward.’

Even as the serf made the announcement, lights began to flash indicating a barrage of urgent hails, vox-servitors babbling like mediums hosting a sudden influx of the unseen.

Draevark felt the creeping stitch of a smile somewhere beneath what he thought of as his face. Evidently sharing his amusement at the lesser vessels’ panic, the Alloyed’s neurolithic relay stabilised the tri-D sufficiently for him to see the effect that the ork asteroid’s appearance had had on the fleet. Ships scattered from its path, line discipline disappearing like dust dunes before a gale. For their part, the orks gave scant heed to the planetary body moving through their armada, taking advantage of the breaks in formation to plunge their ships through the Imperial lines. Some made it close enough to Fabris Callivant to vomit drop pods over the thermosphere. Dogfights criss-crossed the upper atmosphere as House Callivant’s sub-orbital aeronautica were scrambled.

Only the Darkward held resolute. If movement had ever been among its vast suite of powers then the knowledge of how to invoke it had been lost before the rise of the Emperor.

Gravitic strikes. Dark energy lances. Vortex drivers. Magma Annihilators. With a suite of weaponry almost unknown to Imperial artifice and conventional ordnance enough to boil the crust from a small moon, the star fort poured its firepower into the ork asteroid. But destroying a planet was no simple task: even an Iron Hand, resolved to the extermination of a population, generally fell short of the rock beneath their feet. Bands of metallic dust and lumps of regolith, some of the larger bodies with teetering orkish structures still attached and returning fire, clung to the asteroid’s gravity field as it soaked up everything that the Darkward could put out.

The pummelling at least slowed it by fourteen centimetres per second, delaying the inevitable by approximately six minutes.

Draevark saw the Hospitallers’ eight remaining warships altering course, coming about to engage the asteroid. As anyone familiar with their way of war might have predicted.

The Shield of the God-Emperor became more and more isolated as he watched, a screen of increasingly disarrayed Imperial ships falling between it and its brothers. In a minute or two, the Alloyed would be the closest ship to it.

Qarismi had predicted this. He had predicted it and let it happen.

The Imperium and its forces were more usefully regarded as assets than allies, but expending them in so senseless a fashion still sat poorly with Draevark.

<Hail the Shield of the God-Emperor,> canted Qarismi.

‘Why would I?’ Draevark growled.

<Because you are going to offer them your aid.>

‘Offer them…’

Then Draevark understood.

Through his interlink tethers he could sense Jalenghaal’s clave, a cluster of bright sparks in a noospheric void. Space in the hemisphere of Fabris Callivant was hardly dark, but tendrils of communication and data linkage were spread thin over the cosmic distances, a web spun by an electronic spider the size of a moon.

Kristos meant to board the Shield of the God-Emperor.

And he knew why. The same reason he had stolen Draevark’s Apothecary.

He could almost admire Kristos’ thinking, but once again, the Iron Father forgot who he was dealing with.

<Tell them to expect a gunship carrying technical supplies and assistance in approximately seventeen minutes. Then return to your original course and prepare for surface deployment.>

Draevark gave a snarl. Kristos would pay for his trespasses against the Garrsak Clan, and dearly, but Draevark was an Iron Hand; he could afford to be patient. The moment for reprisal would arise, in time.

‘Compliance.’

V

Rauth maintained a bitter flow of invective as Khrysaar kept him moving. He limped on his mauled foot. Every pull on torn muscle drew a gasp. His shoulder, where his use of his brother as a crutch forced their skin to touch, felt as though it were daubed in some corrosive substance. Think of him as an emergency bionic. He gritted his teeth. Endure it.

The street they hurried down was empty.

A full-scale military lockdown had sealed everyone inside their hab blocks or, if their position entitled them, one of the apocalypse shelters buried in the deep bowels of the underhive. Only the occasional armed patrol passed this way, and even they were beginning to wind down as forces withdrew to more critical areas. Ground war loomed.

Nevertheless they kept to the companionways. The jettied upper storeys shielded them from the rain. The power to the worker habs and street lumens had been cut, to darken Fort Callivant to ork bommers as much as possible. A generous assumption on the part of Princeps Callivant’s strategos that ork bommer pilots aim. More than once, the age-darkened splash barriers proved proof against unwelcome attention as convoys of armoured vehicles in the colour markings of the Mordian XXIV rumbled down the rain-slicked highway. They didn’t slow on their way through.

Occasionally, Rauth would see a face peering imploringly from a partially shuttered window after the departing transports. They would fight and live or they would fight and die. And if they should die? Well then they were weak, and their deaths would have cost the Imperium nothing.

‘I can vox Harsid, ask him to slow down,’ offered Mohr.

The Apothecary walked a few metres off the pace, his bolt pistol aimed into the shadows that followed behind them.

You can cut off my leg like a real Apothecary. ‘I can keep up.’

‘I will make sure of it,’ said Khrysaar.

Rauth was unsure whether to take that as a promise or a threat.

The sudden shuddering of the overhanging jetties distracted him from the thought, and he gripped his brother’s shoulder, looking up as a formation of Thunderbolt and Lightning fighters rocketed overhead. This district was wealthy, the preserve of the upper echelons of the Adeptus Mechanicus. As if being able to see the sky is some kind of a gift. They must consider themselves blessed about now, watching their doom come. Burning debris, presumably from ork attack craft, clawed at the sky, bursting apart and smoking out as they punched through rain-thickened clouds.

‘I’ve changed my mind,’ said Rauth. ‘Vox Harsid. Tell him to hurry up.’

Laana ran a short way ahead of them, forced to keep to a brisk clip to keep pace with the genhanced warriors, far enough into the dark and the wet that she would have been invisible if not for the bright yellow overalls that she was still wearing. Her captive stumbled ahead of her, exhausted by the pace that Harsid had set. Even on the run, she managed to hold the magos’ shoulder in one hand and a needler in his back in the other. With his hood drawn and dampened to his head, his servo-harness detached, his ego deflated, he looked smaller than the consumed memories had led Rauth to expect.

Captain Harsid waited for them with vulturine patience by the gates to a walled compound. It looked deserted. The gate was of some artificer wood designed to resemble Terran ebony, the brass flourishes subtly doubling as reinforcements. I’m not looking forward to knocking that down. The Death Spectre turned his beaked helm towards the captive magos. Most Space Marines exploited their armour’s vox capabilities to stun and subdue with sheer volume. Harsid achieved the same with the opposite. He spoke as though every word carried a death sentence for anyone that did not strain to hear.

‘Is this the one?’

‘It… it is,’ said the magos, face down.

‘Are there any security countermeasures?’

‘I… I… I…’

Laana jabbed her needler into the magos’ back.

‘Y-yes,’ he stuttered. ‘But I left my identity cryptex at the tournament.’

‘Do not fear,’ said Harsid. ‘Your door won’t keep us out.’

Before the magos could stammer an answer, the door simply opened itself.

The hairs on Rauth’s denuded body shivered as Autarch Yeldrian appeared inside.

The eldar’s armour luminesced, the effect doubly striking in the near absence of external sources of light, the vibrancy of yellows accentuated by the infinite depths of blues. Empyreal echoes shadowed his movements. Trace arcs of ether light edged the contours of his armour, the jump pack that enclosed his shoulders and pushed him into an elegant bow purring to quiet. The lingering embrace of the warp perhaps, but some aspect of the warrior’s tall, alien helm turned Rauth’s soul to meltwater, a sub-psychic suggestion that bypassed every layer of genhancement and conditioning to attack a fear centre too deep even for the genetic sorceries of the Emperor to reach. Rauth felt Khrysaar stiffen against his shoulder.

Flesh is weak. The mantra ran through Rauth’s head like a warding cant. Flesh is weak.

‘Inside,’ said Yeldrian, his voice dopplered by the eerie helmet he wore.

The magos’ residence conformed to the gothic archetype. The large courtyard was surrounded by high walls. A fortified manse abutted one end. The courtyard was tiered, conforming to an algorithmic pattern, rising towards the house. It was paved with red stone. A few carefully cultivated mosses overflowed from pots. Gunmetal statues depicting Martian Saints stood in poses of contemplation. Rauth’s first thought was that they must be cybernetic artifices, part of some kind of auto-defence system, but on second inspection they appeared to be wholly decorative.

Laana looked around and whistled.

The Adeptus Mechanicus will find a way to thrive anywhere.

The compound gave every indication of being empty, but the Deathwatch team spread into cover regardless. Rauth slumped against the nearest statue, and waved his brother off. Weakness makes me ill-tempered. Khrysaar unholstered his bolt pistol and ran off after Harsid, moving into the shadow of the house.

Rauth turned his face into the rain.

He could almost smell the trickle down from the upper atmosphere. The fyceline of Avenger autocannons. The oxidising fury of Lightning lascannons. The ash and promethium of their kills. It was war. His physiology had been engineered to be responsive to it, and he felt his blood vessels opening for the vasodilators flushed into his cardiopump. His breathing deepened, his thoughts sharpened. His eyes narrowed as he picked out the quartet of black wedges that dropped through the cloud layer like depth charges. A murmur of engine noise rumbled out, touching the ground, as they veered out to hunt for a landing zone a kilometre or two to the west.

No mortal pilot could make entry like that.

‘Yeldrian…’ Rauth murmured.

‘I see them,’ the eldar answered.

‘Clan Garrsak. Heading towards Sevastian’s compound.’

‘I see them.’ The alien’s plastek armour crinkled, like the scales of a serpent shifting position, as Yeldrian turned towards the magos. The human’s eyes bulged. His face lost all shape. ‘Time runs away from me. Like the Wailing Doom it will be mastered by no mortal.’

The magos whimpered, blinking rain out of his eyes.

‘What is your name?’ Laana asked.

‘Cavinash,’ he murmured, unable to drag his eyes from whatever horror unfolded for him alone across the eldar’s mask. More effective than hammers and blades, I’ll admit.

‘We are alone here?’

The magos nodded mutely.

‘You are sure?’ Laana hissed.

‘Household garrisons will have been recalled to the fabricator-locum’s compound.’

Laana nodded. But then she would have known that already. She’s good at this. Rauth found himself wondering just how long she and Yeldrian had been working together. They had an unspoken rapport that seemed to go deeper even than between the autarch and Harsid. What is your interest in all this? Just how did a Medusan Death Cult assassin end up out here with an eldar?

‘This is a fine home,’ Laana continued. ‘Fit for someone important.’

‘I am magos preservator. There are many relics in the temples of Fort Callivant that require maintenance. Many are particular about the rites of reverence they will accept.’

Laana suddenly hauled the magos towards her by the collar of his robes. ‘Was the Dawnbreak device one of those artefacts?’

‘Yes!’

The assassin dumped him onto his back with a disgusted snort, wiping flecks of spittle from her cheek on the sleeve of her coverall. Stronger than she looks too. For a mortal. Perhaps I’ve been harsh. She caught Rauth’s appraising look and scowled.

‘I’ve got this, Iron Hand. Don’t stand up on my account.’

‘Enough, Laana,’ whispered Yeldrian. Cavinash moaned as the horrors being driven into his mind changed once again. ‘Tell me where the artefact lies. Where did Kristos bury it?’

‘Where the fabricator-locum interred it. I took nothing. I swear it. Omnissiah, I swear it. I only allowed some contacts to see it. Collectors, acquirers of the relics I serve.’

‘Hereteks,’ said Laana, with a sneer.

Coming from the assassin at the eldar’s right hand. Rauth’s gaze found Mohr, watching from the other side of the grounds. The Brazen Claw must have read his expression, for he shook his head. Maybe not now, but I will be asking these questions of someone later.

‘I have been magos preservator on Fabris Callivant since before Exar Sevastian ever set foot on this world,’ said Cavinash, finding a measure of courage in the haughty contempt that must have served him so well until now. ‘I know what the Omnissiah commands of me.’ He managed to drag his gaze from the eldar. ‘Do you?’

‘I know what the primarch commands of me,’ said Laana.

‘The? There was more than one you know, girl.’

‘Who cares what any of the others command,’ grunted Rauth.

A hidden smile pulled at the edges of Laana’s face.

‘What of the pits?’ she said. ‘The Aequalis cult?’

Cavinash shook his head. ‘Misunderstood. They simply seek a third path between the flaws of the flesh and the pyramidal orthodoxy of incremental substitution.’ He looked to Rauth, as though believing him his most likely friend. Which doesn’t speak well to his situation. ‘Think about it–’

‘Speak no further.’ Yeldrian’s hand floated like a leaf on the wind, blown by fate and circumstance to the bejewelled grip of his blade.

‘The Voice of Mars sent you. Didn’t he?’

Yeldrian straightened and looked at Laana. Rauth could imagine the order he was going to give.

Had the Darkward not taken that precise moment to die.

He knew it instantly for what it was. The silent explosion rippled outwards from the star fort’s tidally locked orbit above Fort Callivant, back lighting the leaden clouds with yellows and reds. Another explosion followed, even more massive, but equally silent. Unnervingly so. As if gods waged war above the heads of mortal men. And the clouds broke. They burned off, steamed off, evaporated out into the stratosphere as a burning hunk of meteor ripped through them on its terminal plunge towards the planet’s age-blistered crust. Another followed in fiery succession. Then another. Six. Twelve. Twenty-one.

A rok.

That was what the Imperial strategos called them: asteroids fitted with engines, sometimes with armour and basic armament, packed with tens of millions of battle-charged ork warriors, and driven at an unsuspecting world. Orks were inhumanly resilient. If any species could survive entry and impact it was them, and if one per cent of the original cargo reached the surface then that was a massive force to have to face over the devastated ruin of a defensive installation-turned impact crater. They were odds that an Iron Hand would go to war on. The impact with the Darkward had scattered the fragments of the rok away from Fort Callivant. Even so, the resulting tectonics were going to be shattering. Rauth had seen the ancient hive from bottom to top and didn’t think highly of its prospects. Even the upper levels where they were now, which looked immaculate, were built on top of ten kilometres of neglect and corrosion. A single shivered foundation column in the underhive would trigger a cascade collapse that would bring down entire wards and crush millions.

‘Grab him!’

Rauth looked up at Laana’s shout, just in time to see the assassin fire a pair of needles through a potted moss, which then toppled off its plinth and shattered as Cavinash ran past it. Glass needles shattered off walls and statues and sank into artificer oak as the magos took full advantage of the orbital cataclysm to sprint through the open gates.

The assassin swore and plunged after him. Rauth stumbled into pursuit, ignoring the ache in his wounds. Reality folded around Autarch Yeldrian and the eldar vanished into thin air. Rauth shuddered as Laana tore through the gates, swinging round to gun the magos down with a needle shot between the shoulder blades.

The signature clatter of a heavy, tracked vehicle registered with Rauth a split second before it did with the mortal assassin. Wet breaks squealed. A stab-lumen lashed out. Suddenly, Laana was caught in a slash of light. A curfewed street. In the garb of a manufactorum labourer from a recidivist district. Brandishing a pistol and aiming it at the fleeing magos preservator.

Blood of Manus, I’d shoot her.

‘Drop your weapon!’ The shout rang out of the growling wet. ‘Surrender and be treated mercifully.’

Laana’s weapon gasped as it loosed a single shot, then someone opened up with a storm bolter.

Sometimes gods disappoint. That was what Laana said to me. Sometimes gods disappoint even each other.

The assassin disintegrated before his eyes, high-explosive rounds ripping her mortal body apart. Rauth skidded through the gates with a howl of outrage before he could stop himself. A red mist filmed over his face. He clamped his lips shut lest a droplet land on his oomaphagia. It would have felt disrespectful. Go join the primarch’s undying legions then, sister. I hope it’s worth it. He saw that Cavinash was dead too, spread out prone and already beginning to bloat with the assassin’s needle toxin.

For all that mattered now.

‘Sir. Another one here.’

The lamp turned sharply, spearing Rauth against the frame of the gate.

Rauth blinked, but his genhancements compensated quickly. Looming out of the glare was a Chimera armoured transport, iron-grey, the bright hull markings of the Mordian XXIV. Its roof hatch was open, a trooper in royal-blue and gold manually operating the vehicle’s stab-lumen. Parked behind it at an angle was the even greater silhouette of a Leman Russ Eradicator. The tank commander stood in the cupola, hands tense around the grip-studs of the vehicle’s pintle-mounted storm bolter. He was a shimmer of a peaked cap, an anxious glitter of braid.

‘Drop your weapon,’ the Mordian demanded.

Where is Yeldrian?

Rauth licked his lips, drying under the ferocity of the stab-lumen, and raised his hands. He was unaccustomed to having to think on the spot, or for himself.

He was surprised by how naturally it came to him.

‘I am with the Iron Hands,’ he began. ‘I could use transport.’

CHAPTER FOURTEEN

‘Stronger together.’

– Burr

I

The small armoured convoy rumbled down the middle lane of a wide, deserted highway. The Leman Russ Eradicator, Grey Hammer, was in the van. The Chimera, Iron Blood, the rear. A tarp-roofed munitions truck bumped along between them, hammered by the rain. Explosions murmured, nearby, but muffled by the vehicle’s armour and engine noise, the sporadic rattle of small-arms. Rauth and Khrysaar swayed with the Chimera’s adaptive suspension. Rauth stared through the firing slits at nothing. Gloomy buildings and rain. No sign of orks but the odd flicker in the sky. The Mordian Guardsmen shared their transport with him about as willingly as they would with a claustrophobic ogryn. There had been some considerable shuffling along to make space, but Rauth suspected that they would have found room for Mohr as well if the Apothecary had chosen to accompany them.

Khrysaar leant towards his brother’s ear.

‘How did you do that, before, convince them we were part of Kristos’ force?’ Lying by omission came easily to the Iron Hands. They were taciturn by default. But outright fabrication ran contrary to their nature.

‘I don’t know. It just came to me.’

‘What’s the matter, brother? You seem distracted.’

‘I’m thinking about Laana.’

‘Why?’

Why? How many mortals have I killed, seen killed, or allowed to die? Why does this one upset me?

Gods disappoint.

‘I am not sure.’

Rauth turned back to his firing slit, troubled by what he was starting to feel inside, when an explosion blew out the anonymous rockrete of a roadside building and hurled it across all six lanes of the highway. ‘Turn and fire! Turn and fire!’ The command peeled through the vox as the Chimera slammed the breaks and hurled the Guardsmen towards the front of the tank. Rauth watched through the slit as the spiked roller of an ork tank chewed through what was left. It crushed the splash shield that ran the companionway, mangling the metal frame, winding it up through its spikes and shattering the stained glass.

Rauth felt almost relieved.

The troop ramp slammed onto the road and with impeccable order the Mordians stormed out, lasguns snapping into the rain. Khrysaar hauled Rauth up and practically threw him out after them.

He splashed onto the hard-packed rockrete, face first. Something in his chest tore as he scrambled out of the line of fire. Solid ork shells banged against the tank. A Mordian Guardsman took a bullet in the neck and fell in a spray of blood. The others fanned out, using the vehicles for cover, and returned fire. The ork tank’s roller had become fouled up in the power lines and structural wires that had been running through the splash barrier. Black smoke thumped out of its big exhausts as an impatient driver crunched through its lower gears. Meanwhile orks poured out through the ruined barrier and into the road.

Grey Hammer’s heavy bolter mowed them down.

The Leman Russ rocked back, the recoil of its eradicator cannon pushing sixty tonnes of tank onto its rear axial suspensors. The eradicator cannon was not principally an anti-armour weapon. Neither was the heavy bolter glacis mount, nor the twin heavy flamer sponsons. Grey Hammer was built for urban warfare, for murdering infantry street by street, hab by hab, but ork vehicles were always one solid push from collapsing into a pile of bolts. A miniature atomic explosion lifted the battlemented rear turret from the snarled ork vehicle. The mushroom cloud didn’t dissipate so much as sink under the rain. It smothered the collapsed building that the ork tank squatted in as, with a bark of joy pumped out by the vehicle’s crude speakers, the tank finally ground through and took the road. It swayed on its crazy suspension, losing a pair of turret gunners that hadn’t been holding on tightly enough.

There’s always more where they came from.

‘We need to go!’ Khrysaar crabbed towards him, staying low.

‘Were you expecting me to suggest we stay and fight?’

‘You have been behaving oddly, brother.’

Rauth brandished his bolt pistol, masking the twinge that even that much movement pulled in his face. ‘Just don’t slow me down.’

‘That’s the Arven Rauth I used to hate.’

Turning neatly away, Khrysaar drilled the skull of the ork that had been trying to clamber over the splash barrier behind them and blasted it open. It toppled into the companionway, but the explosion brought others running. A hulking warboss with a thick chain wrapped around its fists started pounding on the barrier. Cracks began to spread through the armourglass.

Rauth was already running.

Instinct took him up the street, using the Chimera for cover. The Guardsmen were too preoccupied to notice him go. Either that or they assumed the Space Marines would fight this war their own way. Not too far from the truth. He veered sharply out of the way as the Leman Russ lurched into reverse.

A raucous mob of greenskin fighters charged for the opening. There wasn’t one amongst them smaller than Rauth. Khrysaar grabbed his arm and dragged him behind the Leman Russ. A gout of flame from the battle tank’s sponson rendered the orks to dripping fat, half a dozen unstable legs still trying to get at the two Iron Hands before sluggish nervous systems were apprised of their death.

The two Scouts sprinted up the street, away from the fighting.

Khrysaar took point as Rauth turned, hand pressed to his gut and wincing, and drove bolt-rounds methodically into tusked green faces as they piled out from their tank to give chase. His accuracy was superhuman.

A rocket looped out of the ork-held side of the street and punched through the glacis plate of Iron Blood. As if a Titan had just stepped onto the Chimera’s sloped front, the vehicle rose off its tracks, teetered over the point of no return, then crashed over onto its roof. The Mordians backed away in good order, shedding numbers to ork gunfire, before the rocket finally went off.

The lower front plate blew out, the shrapnel burst throwing the Guardsmen to ground.

This was the sort of war that the Emperor had made the Adeptus Astartes to fight on their behalf. Because they are too weak to fight it for themselves.

‘How far to the forge sacrarium?’ Khrysaar yelled over his shoulder.

‘Did you see me inload a cartolith before we boarded the Chimera?’

‘You had the seat beside the viewing slit.’

An ork bommer bobbed and wobbled across the sky, boosters screaming, before crashing into the hab a few hundred metres down the highway and turning the block into a fireball. More greenskin warriors fought their way out of the building. Most of them sported a burning limb or two, but it didn’t seem to dampen their ferocity.

Rauth pulled up sharply, a splintering pain shooting up his shins.

‘Why are you stopping?’ said Khrysaar.

Rauth made a face that could have been the result of any one of a million personal slights. ‘The road is too wide. We’ll be swamped if we go this way.’ Both arms outstretched, he leapt onto the splash barrier opposite the orks’ side of the road. The barrier curved back, so that vehicle splash would spill onto the highway rather than over passing pedestrians, but its weather-proofed layering had not presented a smooth surface in thousands of years, and Rauth was able to wriggle over the S-curve and fall onto the companionway.

Khrysaar followed him over.

Muffled bullets crunched into the hardened glass.

‘Into the building,’ said Rauth. ‘Keep off the highways, work our way through the habs.’

‘We’ll do this, brother.’ Khrysaar clasped his arm at the bicep. ‘An Iron Hand started this. Two Iron Hands will end it.’

Rauth scowled. ‘Into the damned building.’

The door was locked and barred, but it had never been designed to stand up to an enraged transhuman.

It exploded before Khrysaar’s boot and the two Iron Hands charged inside.

The windows were loosely shuttered. Gunfire and the burning aircraft across the way caused shadows to jump across the floor. Tables were scattered unevenly around the room, chairs stacked against one wall, a counter at the back. An eatery of some kind? It didn’t matter now. He looked back at the broken door. Even an ork won’t need to strain too hard to figure out where we’ve gone. A sudden blast wave rattled the table legs on the floor.

The two Scouts quickly swapped a look.

‘Grey Hammer?’ said Khrysaar.

‘Grey Hammer.’ Rauth pointed to the back of the shop. ‘Move.’

Fort Callivant had withstood the impact of the rok about as well as Rauth had imagined it would and half the highways were blocked or simply destroyed outright, rubble now, demolishing other roads in a cascade going deep into the underhive. The orks that had survived the descent – and some would have – would be hours away at least, but plenty more were landing all the time on primitive drop pods and planetary assault rams. The random nature of their deployment meant their forces were fragmented and small, but everywhere. They would have presented no difficulty to an Iron Hands demi clave, or even a decently prepared Guard outfit, but for two Scouts even a small, fragmented force was a serious obstacle.

They charged from block to block, avoiding ork mobs where they could, feeling no shame in running where they could not.

On a feeder highway, they ran into a gang of gretchin gleefully setting up booby traps, tripwires attached to clusters of stikk bombs, civilians strung up like scarecrows to lure in the unobservant. They gunned the runtish xenos down, revelling in an enemy they could safely slaughter, ignoring the civilians, and drove through the clapboard shutters to the next building in chain. An ork bulldozed through an interior wall and grappled Khrysaar to the floor. Rauth didn’t wait. He’d do no less for me. He burst through the maze of worker dorms, finding himself teetering on the umpteenth floor over a criss-crossing abyss of sagging cables and creaking guttering. An identikit hive block faced him, about six metres away. He took the leap from a standing start. A single shot boomed out in the confined space. A sniper. The auto-round slammed into his bicep just as he landed and rolled into the opposite block. He met up with Khrysaar again as he stumbled through the door. With their combined strength they forced the heavier outer hab doors and staggered out.

The courtyard was a partially domed plaza. Rubble littered the wet flagstones, the crushed wreckage of water fountains and plug-in shrines between freestanding columns. Pilgrims would have congregated here to wait, to pray and to suffer the requisite privation to earn admittance to the forge sacrarium proper. Corpses of the same littered the processionals now. As the principal pedestrian access it had been built to manage large and restive crowds. The fortified narthex on the opposite side was an imposing structure, built thick and high, and home ordinarily to a garrison of several hundred skitarii legionaries.

A pair of Iron Hands in Clan Garrsak insignia held it.

The warriors methodically fired semi-automatic bursts into the orks milling amongst the ruins on that side of the plaza, complementing one another’s angles with the perfection of an algorithm. A few hundred Callivantine families had made it to the narthex’s walls and were hammering on the gate, but the Iron Hands were deaf to their wails. Indeed, it was only when their cries lured the greenskins out of cover that the Iron Hands appeared to mark their presence at all. A storm of bolter fire silenced their screams. Their butchered remains mingled with those of the orks.

The Iron Hands were the masters of urban warfare. Barring none. They did not care about lives or property. Collateral damage did not concern them. If a structure could be bombed to create a choke point or to cut off an avenue of attack, then it would be bombed. They would use civilian shields, shoot into allied forces and exploit Imperial assets to draw enemy forces in before retaliating with overwhelming firepower. The Hammer and the Storm, it had once been called. The use of viral, chemical or rad-weaponry to neutralise whole quarters of a ‘friendly’ city was far from beneath their consciences.

We could teach the Imperial Fists a lesson or two. If they would listen.

‘I see it.’ Khrysaar pointed to a copper-faced spire, just visible through the swirling rain and the layered energy haze that blanketed the forge sacrarium. ‘On the other side of the narthex.’

‘Let’s go,’ said Rauth.

A couple of ramshackle ork Dreadnoughts and a superheavy wagon laden with jeering troops rattled towards the narthex. The two Iron Hands on the battlements were suddenly conspicuous by their absence.

Throne!

The string of demo charges knocked down the narthex’s high walls one at a time, burying the greenskin assault in a tsunami of red dust and leaving a cliff of shattered bricks where the fortress had been.

Rauth’s jaw muscles bunched in frustration.

‘We’ll need another way through.’

A gunshot blew out the lintel of the door they were standing under, and both warriors turned to see a pack of orks pouring into the vestibule behind them. Rauth blew out his cheeks.

‘We’ll cross that bridge later.’

They left the orks blasting impotently into the air as they sprinted for the narthex. Exertion was starting to blur Rauth’s vision as a mob of bikers roared onto the plaza on a diagonal, trailing tin cans on lengths of string, with scraps of flag bearing lightning bolts and crude rocket glyphs whipping out behind them.

Khrysaar opened fire on the bikes. His shots pranged their armoured frames as they jinked and pulled wheelies. Rauth spun towards the orks behind. It’s actually a relief to stop running. A tremor ran through the ground before he had his pistol in line with the first ork’s brow. A gust of warm air rolled over him, as if a fire elemental had just exhaled, and before Rauth was even aware that something had happened the ork bikes vanished under a saturation missile strike. Sizzling bits of spoke and fender pattered over the flagstones, nothing left of the squadron but a crater six metres across.

Rauth looked back to the pursuing orks.

They were drawing back to the hab, a look on their dull faces that took Rauth time to recognise simply because he had never seen it expressed by an ork before now. A brutish blend of horror and surprise. He turned to see what they were looking at. He tilted his head further back. His mouth dropped the other way.

It was Princeps Fabris.

II

In a final blast of stabilisation jets, the Three lowered onto the hurriedly cleared landing block aboard the Shield of the God-Emperor. Tonsured serfs in billowing white surplices bearing the Hospitallers cross approached, bent against the downwash from the Thunderhawk’s cycling turbofans. A thick-necked mortal armsman led them out. He wore the same devotional garb as his brothers but under a black breastplate and bracers, a ceremonial broadsword strapped across his shoulders. He was forced to jog to keep pace with the tech-priest that scuttled towards the gunship’s lowering ramp.

The magos prostrated himself on the deck just as the embarkation ramp rattled home and locked. ‘You are welcome aboard my charge.’ He looked up from his position of abasement as the first Space Marines clumped down the ramp. ‘The reputation of your Chapter as machine-whisperers and masters of artifice precedes you. Pray inform Iron Father Kristos that his munificence will be recompensed in commensurate measure.’

Jalenghaal regarded the prostrate human uncomfortably. ‘Mirkal Alfaran has left the ship, is that correct?’

‘Aboard the Inviolate Zeal, lord, yes, to take the sword to the unclean vessels of the xenos.’

‘How many Hospitallers remain aboard?’

‘Two squads, I believe.’ The magos glanced enquiringly to the armsman, who spared a nod.

‘And Venerable Galvarro, does he remain upon the bridge?’

‘Yes, lord.’ The magos sounded confused. ‘Do you wish to see him before I take you to the drive chamber?’

‘I do,’ said Jalenghaal and unlocked his bolt pistol sidearm.

The bolt overshot the gaping magos and punched through the armsman’s breastplate. It detonated, blowing the mortal warrior’s torso inside out. The armsman’s own chest shielded the other serfs from the blast, but the gory eruption stunned them long enough for Jalenghaal to shift aim and fire again. They were close-packed, unprepared; the four-shot burst exterminated them all.

‘What are you–?’

Burr shot the magos dead, a single round from the hip.

‘I could grow accustomed to this,’ he said.

Jalenghaal was uncertain whether he meant forcing entrance to an allied vessel or murdering tech-priests in cold blood, and decided not to enquire. He swung his aim ninety degrees, short-range helm auspex scanning the embarkation deck for threat pings. The Hospitallers had not left so much as a single Storm Eagle behind. Borrg made a disappointed sound as the rest of the Iron Hands tramped out of the Three.

‘An easy mission is a mission accomplished,’ Thorrn chided the neophyte.

‘It will not be easy,’ said Jalenghaal, his boots making a red mess of the Hospitallers’ welcoming party as he strode for the exit hatch. He blink-clinked a rune in his helm displays, parcelling off a section of his augmented consciousness to replay Kristos’ simulus log in the background. ‘It is a long way to the bridge.’

And Galvarro would be waiting for them when they got there.

III

Princeps Fabris stood in the middle of the burning highway, ten metres tall, smoke spiralling from the discharged missile tubes in his carapace hardpoint. The Knight Crusader was armoured in an eccentric pattern of purple-and-black adamantium plates, each emblazoned in the emblems of House Callivant and heraldic allusions to a warrior ancestry stretching back eleven thousand years. Twin banners fluttered between the Knight’s legs, announcing its allegiances both to Mars and to the old Iron Tenth. A ghost flicker chased its titanic outline as the Knight’s ion shield repulsed rain and ork fire with equal vehemence. Raising arms outfitted with heavy stubber and rapid-fire battlecannon, the princeps turned the escaping orks into short-lived puffs of flesh, bringing down the entire face of the hab that Rauth and Khrysaar had just fled. His speakers emitted a war-song at cacophonous volume as he did so. And why not? The ground trembled as the god of iron strode onto the courtyard.

Fabris thudded to a halt before the two Iron Hands, then tilted his almighty torso to greet them. One honour brother welcoming another to the tourney field. Given the awesome size differential it should have come across as ridiculous, but the Knight’s throbbing aura of machine power had left Rauth numb.

‘Well met upon the fields of glory, Iron Hands,’ Fabris declared. ‘Reap the bounty while it is offered, say I, for the greenskins shall not be so accommodating once their main force arrives.’

Rauth’s voice was tiny in comparison, and it took him longer than he would have liked to find it. ‘Should you be alone?’

The princeps’ laughter boomed against the buildings that still stood. ‘Should you?’

Rauth looked down, embarrassed, as though the tenor of the god-machine’s vibrations were having some influence on his flesh. The thought gave him the germ of an idea. He had heard that those bonded to the body of a Knight were not like other men. The machine’s spirit altered them, made them care about things that Rauth knew a warrior should not. Things like honour, brotherhood, sacrifice.

He looked back, raising his voice. ‘We are on a mission of great importance. The…’ Unfamiliarity caught the word in his throat. He expelled it on a shout. ‘…honour of my Chapter depends on our return to the forge sacrarium.’

Khrysaar looked at him as though he spoke in alien tongues.

‘We can’t fight every ork in Fort Callivant,’ Rauth hissed to him. With his eyes, he gestured to the mighty war machine. ‘But he can.’

‘Attend me then, bold heroes.’ A building crumbled as the rippling sound waves of the princeps’ speakers finally took their toll. His arm-mounts swivelled, banners rippling as his giant stride carried him directly over the two Iron Hands’ heads and away. ‘For war. For honour!’

IV

Jalenghaal fired back down the corridor. The torrent of bolt shells broke open the shields of the armsmen that boiled up from the deck below. They had lived and fought alongside Adeptus Astartes all their lives; they must have understood what they faced, and yet they came to face it regardless. Jalenghaal felt that he should be impressed by such courage, but their stupidity left him cold.

Grinning dementedly, Borrg ignited his flamer and rinsed the wall of shields.

Shields popped and clanged to the deck as the fat melted from hands. Men thrashed and rolled, screaming until the promethium they inhaled burned away their lungs.

The neophyte gave the corridor another hosing. In case there were any more armsmen on the Shield of the God-Emperor feeling brave.

The soldiers’ ammunition belts cooked off in a blitz of minor detonations that made Lurrgol start. The Iron Hand swung back and opened up on the bulkhead. Borrg cursed, shutting off his flamer hose to shield his eyes as he was pelted with ricochets. Thorrn stove the back of the old warrior’s helmet with his bolter’s stock.

‘I think I hit it,’ said Lurrgol, lowering his bolter.

‘You hit something,’ Thorrn answered darkly.

A short blast of heavy auto-fire drew everyone’s attention back up the passageway. It was followed immediately by a thump of something large and hollow hitting the deck. An ident-blip in Jalenghaal’s helm display turned red. Deimion was down. Strontius’ signifier was the closest to his position. Jalenghaal blink-selected the icon and routed the warrior’s optical inputs to his screens.

The blast doors to the main bridge were ahead of him. A hundred metres ahead. They were partially hidden from Strontius’ optics by the angle of the corridor, designed to funnel an enemy into the enfilade of its sentry guns before letting them even within sight of the doors. They were just ahead. A pair of quad-linked autocannons, activated by heat or by movement. The view shifted as Strontius dropped into the cover of his heavily armoured brother and returned fire. The shot was rushed and the lascannon blasted harmlessly against the doors. Standard plasteel-adamantite composite with an energy-proofing ceramite sheath. It would take something bigger than a lascannon to get through.

Jalenghaal blinked back to his own senses, taking a moment to absorb the break in inputs, then summoned Lurrgol.

Without speaking, Jalenghaal mag-clamped a melta bomb to his brother’s back. Wordlessly following his example, Borrg, Thorrn, Burr and the others grimly copied the routine until the Iron Hand was covered in bulky charges.

‘Stronger together,’ Burr said, putting rare words to the unspoken idiom of the Garrsak Clan.

Lurrgol seemed to deflate. ‘I understand.’

Lurrgol. Burr. Jalenghaal. The three of them had been closer than brothers since their elevation into Clan Garrsak to cover the losses suffered on Dorloth II. One hundred and forty years together.

Jalenghaal would not miss his brother.

Lurrgol started walking.

Clave Jalenghaal fell in behind him.

V

Rauth lost track of the number of orks he had watched Princeps Fabris annihilate, the number of bikes, trucks and buggies left smouldering in their wake. More than Khrysaar and I could have handled. His own magazine ran dry after about half an hour. He chided himself for that. Compared to the Knight’s firepower, his own contribution was entirely unnecessary. He hadn’t expected the search for a clear route through to the forge sacrarium to take so long. Fabris too seemed equally frustrated. His Knight’s loping stride extended to devour the kilometres. Rubbled habs and open highway vanished beneath him with equal haste. No quantity of foe seemed capable even of slowing him down, and Rauth and Khrysaar endured the better part of an hour in a scrambling, muscle-sapping sprint through devastated terrain before they found their way in.

It will be the only one.

Rauth was sure of it. He held up a hand to warn Princeps Fabris from venturing any further.

Judging from the small size of the road, its lack of companionway and the overhead sigils warning vehicles to turn back or be fired upon, it had been an access road preserved for senior magi. Perhaps even for the fabricator-locum himself. A gauntlet of impacted civilian vehicles turned the narrow strait into a nightmarish zigzag of tank traps, stinger matts and anti-personnel weapons. Ork bodies littered the gauntlet, every one of them dropped by a single explosive shot to the head. That immediately struck Rauth as off. Iron Hands are not so discriminate, or precise. Not at that range. The ziggurat of the forge sacrarium rose in stepped tiers on the other side of the kill-zone. It was surrounded by a high wall stamped with runes of repulsion, abjuration and electrocution, and topped by coiled barbs that hummed with bound charge.

‘I do not see you, neophyte!’

The voice bounced over the crushed vehicles from somewhere on those walls. It would be referring to the tactica displays of the speaker’s helmet, to which Rauth and Khrysaar would be appearing as perverse blanks. After so much time in the company of outsiders, it felt strange to hear the voice of one of his brothers again, the abstract ways in which they chose to perceive the universe.

‘You are not Garrsak. Are you one of Sergeant Tartrak’s strays?’

Rauth and Khrysaar shared a look. Tartrak. Being recognised would be the quickest way to derail this mission. Khrysaar opened his mouth to call back across, but Rauth stayed him with a touch to his arm, lips pursed in thought.

‘Yes,’ he yelled. ‘Tartrak demands you admit us immediately.’

The pattering of rain on metal filled the silence, presumably while the voice on the other side conferred with a superior officer. Rauth comforted himself with that. There were blacker names than Tartrak amongst the thousand of the Iron Hands, but not many.

Kristos, for instance.

He pushed the stray thought aside with a scowl.

‘You’ve changed, brother.’ Khrysaar leant in to regard him suspiciously. ‘You’ve become more like Harsid. Like Yeldrian.’

The blast of a war-horn prevented Rauth from telling his brother just what he thought of that.

‘This then is my part done, friends.’ The bow wave of Fabris’ speakers flattened Rauth’s face to his skull. ‘Go with honour. Seek out my palace when the day is carried and regale me with the tale of your success.’

The possibility that anyone with a righteous cause could fail doesn’t even penetrate, does it? We should all wear armour like yours. Nevertheless, he could not deny a pinch of regret at seeing the back of the Knight princeps.

Khrysaar tugged on his shoulder.

A servitor shambled from the gauntlet, dragging its swollen feet through the ground litter of debris. The battle between rot and the arcane preservative sciences of the magos biologis was a stalemate of conflicting odours. Sloughing flesh clung to age-stiffened bionics, and the unit appeared to emit a gasp of corpse gas as it stopped. The two Iron Hands waited for it to do something, and almost immediately it began walking backwards, the trailing umbilical cable slotted into the back of its head pulled taut.

‘Follow its footsteps closely!’

Without a word shared between them, Rauth and Khrysaar followed.

After what felt like ten or fifteen minutes but could only have been one or two, the scouts emerged from the gauntlet. A pristine kill-zone extended about two hundred metres further to the sacrarium walls. Rauth’s skin prickled, sensing, in that crude yet remarkably prescient organic way, the heavy weaponry trained upon him. The servitor continued its retreat into the casket that held a winching mechanism and the other end of its umbilical, iron shutters slamming down to seal it in.

The sacrarium gates opened.

A pair of Tarantula sentry guns greeted the two scouts on the other side. The pieces were uncrewed, operating solely on the guidance of their machine-spirits. They twitched, and Rauth stiffened as he passed between them. What mere warrior could say how such a mind divined friend from foe? They took the conscious decision to not rip him to shreds, however, and with that implied favour on his objective, Rauth felt himself smile.

Perhaps the Omnissiah looks kindly on me after all.

Whirlwind and Predator tanks were parked around the compound. The Predators were hull down, surrounded by sandbags and razor wire, turret-mounted lascannons trained on the now-closing gate. The Whirlwinds had been situated less precisely, but just as deliberately, closer to the ziggurat, missile racks angled up at the pregnant sky. An Iron Hands tactical clave stood around them, utterly immobile, armour dark with rain. Two demi-claves of Devastators stood on the walls, equally absolute in their patience.

The only moving figure that Rauth could see was a Chaplain, identifiable by his skull helm and the Cog Mechanicus on his armour, and the crozius in his hand as he descended from the walls. Rauth estimated twenty to twenty-five warriors. Even Yeldrian was never going to get in here by force.

‘I am Braavos.’ The Iron Chaplain was a colossus of corded cable-bundles and skeletal plate, criss-crossed with fibres like the taut augmusculature of a gladiator. His lenses glowed with the bitter light of the knowingly damned. Sensor and communications apparatus protruded from his helmet like horns. He could not have appeared more chillingly daemonic if that had been his stated intent. ‘What do you want, neophytes?’

Rauth worked his dry lips. Perhaps he had been apart from his own for too long, but the Iron Chaplain gave him shivers.

‘Sergeant Tartrak requires access to your vox-net,’ he said. ‘Ours was damaged in the hive quake, and we can no longer receive from the Omnipotence.’

‘Typical Borrgos trash.’ No Iron Hand is buried so deep in iron that they can resist a reminder of their superiority. ‘I will summon a warrior to show you the way.’

‘That will be unnecessary,’ said Khrysaar, quickly.

Too quickly.

Braavos glared at him, suspiciously.

‘You will soon need every warrior on the walls,’ said Rauth.

The red glow turned on Rauth. ‘Yes. I saw how you had Princeps Fabris handhold you through Fort Callivant. Impressive.’ The Chaplain dismissed the two scouts by the simple expediency of walking away.

Khrysaar looked up at the arc-lit ziggurat with thinly masked anticipation. Rauth understood all too well. The Dawnbreak Technology is in there. It’s all been for this. He touched his brother inconspicuously on the arm and gestured for the steps.

VI

A pair of quad autocannons would shred even an Iron Hand and Lurrgol had been biologically dead for seven point two seconds by the time his armour made it to the blast door. The melta charges that the clave had clamped deliberately to his back activated the moment that he did.

The blast ripped through the heavily reinforced door, crumpled down the corridor and tore the two sentry turrets to metal filings.

It took another half-second for the blast heat to diminish to within the upper tolerances of Mk VII power armour. And then, in three ranks of three, the battle automata of the Iron Hands, the Garrsak Clan marched into the inferno.

Jalenghaal remembered the layout of the Shield of the God-Emperor’s bridge from the simulus chamber. The frescoed dome soared overhead, the Emperor staring down in impotent judgement from His Golden Throne. The brass pipes of a vast organ crawled up the high walls. Gold glittered everywhere. Votive candles burned on plinths, tables and sconces, borne by serfs, hanging from candelabra. Skulls and holy weapons gleamed from within stasis-fielded reliquaries. Even the metal of the bulkheads had been shaped, millions of man-hours going into crafting the illusion that this was a ship not of plasteel and adamantium but the bones of some golden behemoth. Thousands of serfs filled myriad stations, from the ceremonial to the critical. Hundreds of armsmen stood around command lecterns, armed with short-barrelled shotguns, automatic pistols and heavy broadswords.

They were still recoiling from the blast as Clave Jalenghaal came in firing, mowing through defenceless serfs and mortal soldiers alike. The Iron Hands glowed like metal from the forge, painful even to look upon, lethal to the touch, as they methodically dismembered the Shield of the God-Emperor’s bridge functions and crew.

Over the solid hammering of his bolter Jalenghaal heard a whine, like a starting engine, and Strontius simply dissolved where he had been standing.

The deck trembled. Bells tolled for vengeance.

And Venerable Galvarro reloaded.

VII

‘Have you disabled the hyperios batteries?’ Rauth shouted.

‘I think so,’ Khrysaar yelled back, spitting out rain. His pale skin was blueing, carapace dripping. His optic gleamed like a pearl under water.

The forge sacrarium’s vox-grids were controlled from a master suite inside the ziggurat’s upper levels, which would have mattered more if Rauth had ever actually needed to reach a ship in orbit. Several landing platforms petalled off from the ziggurat’s rain-beaten crown and it was to those that the two scouts had headed. Visibility was in the low tens of metres. Against the relentless murder of raindrops on weathered rockrete, the war for Fabris Callivant was an unconfirmed rumour of engine noise and gunfire.

‘Unless you wish to see Little Grey punched out of the sky in the next thirty seconds you’d better be more certain than that.’

‘I’m no Techmarine,’ Khrysaar scowled.

Rauth grunted an acknowledgement, shrugging rainwater from the hunch in his shoulders, and returned his attention to the communication panes.

The tension was getting to him.

Braavos and his warriors were several hundred metres below, but the sacrarium ziggurat still teemed with tech-priests and their indentured labour. Despite the Iron Chaplain’s colossal disinterest in the scouts’ business, it couldn’t be long before it dawned on him that they had not gone to vox-control.

We should have gone straight for the quarantine silos. This could all be over already.

‘Is the shuttle definitely inbound?’ called Khrysaar. ‘I can’t hear it.’

‘I can’t hear anything!’ Rauth smeared the layer of wetness that was diffracting the pictorial display on his runescreen. He squinted over the inscrutable icons. ‘I think so.’

Khrysaar gave a wet snort of laughter.

The dulled whine of a rotary engine hovering in a storm drew Rauth’s attention skywards.

Rain beat harmlessly off the mucranoid gel coating his eyes, and the smudge of a hooded lumen glanced the light-harvesting cells of his retinas. Little Grey. The meteorology of Fabris Callivant was enough to shield it from a visual identification from the Iron Hands garrison. The technical modifications installed by Yeldrian and Harsid’s expert handling did the rest. Rauth watched it take position over the platform, hearing the minor shift in pitch and volume as the shuttle’s vectored engines switched to vertical lift. When the lumen smear did not blossom into a fireball, he turned to throw a brief nod in Khrysaar’s direction. It looks like we’ve both picked up a little more Martian lore from Tartrak than we realised. A length of heavy duty rope thumped to the platform, superfluous length piling up into an anchor, weighted by the sheer mass of absorbed moisture.

Harsid slid down, water spraying from his gauntlets, bolter mag-clamped to his backplate, landing on tiptoes with less of a sound than a single drop of rain amidst the downpour.

The Death Spectre was moving before his heels touched down, bolter in hand, black armour dissolving into the rain like oxygen into dark alien blood. Even as Rauth’s eyes tried to track the Deathwatch captain, he felt the now-familiar twisting sensation in his gut as Yeldrian stepped out of nothing to appear on the platform beside him. Rauth swallowed several times clearing the clench in his throat.

‘Why did you need to do this in person?’ Rauth asked. ‘My brother and I could have located the device and met you with it here?’

‘You have done all you can.’ Yeldrian’s distorted voice rebounded off the raindrops, as though the eldar were everywhere. His armour shimmered, wet, somehow making the alien appear even taller than he was. ‘The Dawnbreak device will be well guarded, but there are other reasons why it can only be me that claims it.’

‘Reasons?’ Rauth’s patience for half-answers and evasions was starting to run thin. ‘What r–’

A sound reminiscent of a forge power hammer stamping the side armour of a tank rang over the platform.

Harsid crashed out of the rain and screeched across the rockrete, sparks doused at source, dragging to a stop a metre or so from Yeldrian’s boots. The Death Spectre groaned, but failed to get up. A massive hole had been blown out of his plastron.

Lightning wreathed the rain where the Deathwatch captain had been.

Yeldrian calmly drew his sword as a Terminator-armoured Iron Hand emerged from the rain.

‘I was hoping you would say that,’ said Iron Captain Draevark.

VIII

A thousand years ago, Chaplain Fenecha had taken Galvarro’s face in his hands, stared into his eyes and told the young Space Marine of the death he foresaw.

It was not now. It was not like this.

Ignoring the prattle of small-arms he locked his splayed feet to the deck and pivoted. The first of his kills had wielded a lascannon. A tank killer. Without framing his thought processes in such prosaic terms he assessed the remaining seven targets. Bolters. A flamer. He fixed his vid-captors on a warrior hefting a plasma cannon, angled his arm-mounted weapon for the renegade Space Marine’s movement, locked and fired again.

One hundred mid-calibre rounds per second obliterated the Iron Hand and cast the ash of his soul to the wind.

He pivoted, still firing, spraying rounds through a forty-five degree cone that punched down another Iron Hand and indiscriminately murdered dozens of his own crew.

Better to deny their deaths to the heretic.

‘What are you, Kristos, but a latter day Horus?’ he raged. The muffled pop of bolt-rounds hitting his armour, unable to penetrate and so failing to explode, echoed through his uterine tank. ‘A Huron. An Abaddon. You have felt the Emperor’s light and turned from it. Come now. Embrace His forgiveness.’ The Iron Hand he had injured dragged himself behind a lectern, which Galvarro duly shredded with a prolonged burst, tearing the warrior’s armour with shards of splintered ceramic.

Strangely reluctant to receive his arm cannon’s absolution, an unhelmed warrior approached from outside his fire arc and bathed his leg in fire.

He felt nothing.

They could not hurt him and they knew it.

With a sharp twist of his upper body he thumped his power fist into the flamer warrior’s plastron, pinched its teeth to grip the ceramite, then raised him off the deck.

There was a time when he too had possessed the death sight. Not with the refinement of Chaplain Fenecha, but he had been able to read a man’s soul. He had lost the gift along with his mortal eyes, and he saw nothing in the Iron Hand’s spirit but madness and rage.

Concentric rings of adamantium teeth spun in opposing directions like propellers, blending the Space Marine in his armour and spraying his vaporised remains like a libation to the God-Emperor.

What did that leave now?

Five?

‘What do you hope to gain from this betrayal, Kristos? I will free the souls of your warriors, and then I will come to free yours.’

‘I do not believe he has one.’

A heavily augmeticised warrior with a cog-toothed, century-service stud machined into his helmet rose from cover and tossed a grenade underarm towards Galvarro.

IX

The ground shook as Draevark gathered momentum. A pistol materialised in Yeldrian’s hand, bolts of laser energy scattering off Terminator armour like baptismal oils flung at the hull of a battle tank. Flinging himself out of the iron captain’s path, Rauth drew his knife, cursing himself yet again for expending so much ammunition on the orks. Yeldrian butterflied his blade. He won’t even slow Draevark down. The absolute certainty of a violent death drew Rauth’s eye like a collapsing star. He watched, still pushing himself along the rain-slicked platform on his back, as Draevark’s lightning claw hacked through Yeldrian. The autarch’s image shimmered to nothing. Draevark emitted a grunt of confusion, then the autarch’s blued sword erupted in a bloodless explosion from his chest.

The iron captain struck back with an elbow.

No pain. No surprise.

No weakness.

The materium split to swallow Yeldrian before the elbow hit, and Draevark’s arm punched only through maimed air. A humanoid corposant lit up Khrysaar’s runebank, ten or so metres distant, an instant before a blizzard of alien laser fire bracketed the iron captain.

An eye-lens exploded, laser bolts obliterating the benedictions chiselled into the armaplas as the iron captain ground about and raised a lightning-sheathed gauntlet. Rainwater hissed to steam. Khrysaar rolled from cover as flame jetted from the underslung weapon mount. The runebank wasn’t so graceful. It erupted into a column of fire and debris that stole a temporary outline of the Little Grey from the clouds it hid within.

The shuttle was still circling, presumably with Cullas Mohr now in the pilot’s throne.

Rauth slipped and crawled towards the still form of Captain Harsid as Draevark slowly punished the rockrete between him and Yeldrian.

The Death Spectre didn’t respond. The cavity in his chest plate was a gristly, stringy mess, a waxy white film already partially coating the damaged organs. Mucranoid secretions. Harsid was falling into a sus-an coma, the last resort for a Space Marine injured beyond even a transhuman physiology’s capacity to regenerate. Draevark did that with one hit. Rauth slid his bionic fingers between the Death Spectre’s gorget ring and his helmet, and pulled. With a howl, he tore Harsid’s helmet from his head, the sudden wrenching of its clasps causing it to fly clear over the edge of the platform.

Harsid’s face was coated in more of the same waxy substance. Rauth felt no breath on his hand as he reached across his captain’s mouth to manually activate the vox-controls concealed inside the gorget ring.

‘Mohr, get down here. We need–’

Another gout of flame rolled towards him, and he dropped flat to his chest, the burning wash of promethium dragging the moisture from his face.

‘You. You are an Iron Hand.’ Draevark’s shoulders rolled with the titanic girth of his armour. The sputtering exit wound in his chest plating framed a view of the fire pit behind him, all that remained of Khrysaar’s hiding place. ‘Did Kristos send you? Or was it Qarismi? Did the magos calculi tell you that you would die today? If not his powers of prognostication are not as he professes them to be.’

Rauth held his knife between them as he backed away. Draevark chuckled, a bleak venting of waste air from his doubly reinforced helmet radiators. With a grunt of acknowledgement, Rauth tossed away the knife.

Iron Hands don’t do last stands.

‘We are here for the Dawnbreak Technology,’ Rauth said.

‘The what?’

Rauth opened his mouth to answer, but to his surprise a harsh laugh forced its way through instead. He doesn’t know. He’s iron captain of the Garrsak Clan and he doesn’t know.

‘The sister of the Thennos device,’ said Rauth.

‘The artefact that Jalenghaal and Stronos unearthed there. There was another?’ Another low growl rumbled from his speakers. Lightning rinsed his metre-long claws. ‘Kristos brought it here?’

Rauth backed away until his heels hovered over empty space, nothing at his back but swirling rain.

‘He used my clan to guard it for him, but why, where is the logic?’ The iron captain’s lenses flickered as his helmet displays cogitated the problem. ‘He wishes to remove it before the orks come, as he did on Dawnbreak to the eldar. Of course.’

Quicker than Rauth would have imagined Tactical Dreadnought armour could move, the iron captain had him by the throat. The meat of his neck sizzled. His feet left the ground.

‘He intends for it to be Clan Garrsak that bears the blame this time,’ the iron captain hissed. ‘Kristos underestimates me for the last time.’

Instinct made Rauth attempt to pry the talons away. There was a discharge and a burned ozone smell as the sheathing power field shocked his hands back to his side.

He gurgled on a scream.

‘Yet he sends two scouts to see it done,’ Draevark snarled. ‘A weakling get of Corax and an alien. How best to send Kristos a message? How best to let him understand the depth of his failure?’

The rain beating on the iron captain’s armour began to warp and discolour.

Rauth cocked a bloody grin, but hadn’t the breath to fashion the retort on his lips. Do it, Yeldrian. Do it now.

In an explosion of primary-coloured alien plastek the autarch burst from the rain, striking a decapitating blow. Without turning to face him, Draevark caught the eldar’s blade between the talons of his other gauntlet. The alien’s power field merged with his own, throwing out hissing arcs and tortured bolts of electricity. Yeldrian strained, his Banshee masque melting and reshaping as it probed the iron captain’s psyche for some deep-seated, long-forgotten mortal dread. Draevark did not look as though restraining two combatants was any effort at all.

‘Only one question eludes me – why would you work for Kristos, alien?’

‘I do not,’ Yeldrian hissed, still pushing against his trapped blade. ‘I have been fighting Kristos for two hundred years. The Cycle renews. I was the eldar he took it from on Dawnbreak. I was the one fated to arrive on a devastated world to find my farseer dead and the artefact gone. He divided it into three. Perhaps he knew the significance of the number to our mythology, or perhaps our gods work through him. One part went to Thennos. One part to Mars. One part here.’

‘Where is the Thennosian part now?’ said Draevark.

‘Your home world, I believe. I have an agent there searching.’

‘Tricks and lies.’

A hard turn of the wrist sent Yeldrian’s blade flying and the eldar himself into a controlled cartwheel, landing spread across hands and knees with his laser pistol aimed at Draevark’s damaged helmet. He didn’t fire.

What are you waiting for? Rauth’s senses were starting to retreat inwards. He could feel his multi-lung straining, scavenging every last molecule of unused oxygen still in his body. Shoot him.

‘His name is Lydriik,’ said Yeldrian.

There was a snap of dissipating charge as the talon at Rauth’s throat deactivated, and he gasped, giddy on the sudden intake of breath.

‘I know Lydriik.’ The iron captain turned his scarred helmet towards Rauth, twitching and jerking like a worm in his grip. He emitted a crackling growl-sound. ‘I will not be played like a pawn. Take it. Damn Kristos, and let him know that it was Iron Captain Draevark of Clan Garrsak that did it.’

The Dreadnought was down, spiders of haywire energy crawling across his ornate sarcophagus before scuttling into the metal. The warrior within would still be alive, but blind, deaf, dumb and in excruciating pain most likely. Jalenghaal stabbed a teleport homer onto the Dreadnought’s engraved front plating, a mote of empathy floating just out of his mind’s reach. The Venerable had been weak. He had been strong. That was the end to it.

Around him Thorrn and Burr, Karrth and Hugon, the last warriors of his clave shot into the crowd. With Galvarro disabled and the shipmaster slain it was slaughtering livestock, and that was how the Iron Hands preferred it. Burr took the time to cut high-value bionics from the fallen and to salvage Strontius’ lascannon. The warriors’ gene-seed was of lesser concern, and in any case they had no Apothecary. The others withdrew into a defensive ring.

The teleport homer pulsed in rapid sequence. A warning ping went off in Jalenghaal’s brain, and his whole body seemed to clench in anticipation.

A feeling of absolute cold enveloped him as the teleporter dragged his abused soul into the warp.

His iron shell followed a moment later, as though reluctant. The delay was miniscule, but in the dimensionless void of the empyrean all spans of time stretch eternal. A sense of collapse followed, as if he were being driven through a pinhead singularity, as soul and body reunited in the form that best fit the moment and the caprice of quantum uncertainty.

‘Ave Omnissiah,’ he murmured on emerging, to all available parameters, whole.

The battle-torn bridge of the Shield of the God-Emperor was gone. In its place was a frigid chamber, low-ceilinged and barely lit. Metal slabs crowded the floor space, aggressively polished and shiny despite the gloom. Glass tanks filled with bubbling fluids lined the walls. Bits of metal glinted there. An arm. A leg. Bits of armour. It was the apothecarium. Jalenghaal was back aboard the Omnipotence.

‘Disorientation. Symptomatic of teleportation.’ Apothecary Dumaar looked from the operating slab he had been bent over. It was blanketed in the blueish shimmer of an unstable stasis field. His twin optics clicked and whirred as they focused on the five steaming Iron Hands and the haywired Dreadnought that had materialised before him. ‘Recommend complete cybernetic reconstruction of the vestibular system.’

‘My vestibulocerebellum is already one hundred per cent bionic,’ said Jalenghaal.

Dumaar remained still as he considered. ‘Then I have no recommendation.’

The apothecarium doors hissed open and Niholos and Haas walked in, Magos Qarismi following, his geometric puzzle-staff clicking on the bare decking. At the sight of Galvarro, the magos calculi appeared to grin, but then he always appeared to grin.

‘Minimal damage,’ said Niholos, running his probe-talons over the mezzotint reliefs on Galvarro’s sarcophagus. He shook his head, apparently dissatisfied, but said, ‘It will suffice.’

‘Garrsak concurs,’ said Haas.

‘Preliminary stage, liquefy remains and drain cyborganics.’ Dumaar’s gaze tracked lazily from Jalenghaal to the Dreadnought. ‘The starter feed will ameliorate the effects of stasis shock, and facilitate First Sergeant Telarrch’s uterine attachment.’

‘You speak of a hero,’ said Niholos. ‘Speak his name at the very least.’

Dumaar did nothing to indicate that he had heard.

‘Telarrch will make better use of his iron,’ said Haas, quietly.

‘We do the Imperium a great service today,’ said Qarismi. His skull regarded each of the Apothecaries in turn.

‘The Hospitallers will not see it that way,’ Jalenghaal interrupted.

The light carved the edges of Qarismi’s skull as he turned towards Jalenghaal’s demi-clave. ‘They are emotional creatures,’ he said, as though addressing a neophyte. ‘It blinds them to rationality.’

Jalenghaal did not dispute that. ‘Where is Iron Father Kristos?’

The magos calculi shared a look with the Apothecaries. Or with Haas and Niholos anyway. Dumaar’s transitory attention had already returned to the stasis slab. ‘He is occupied elsewhere.’

‘Are we then released? We should rejoin Iron Captain Draevark on the planet’s surface.’

‘Did you not hear?’ said Niholos, voice bitter. ‘Draevark betrayed us. He surrendered Kristos’ prize to the Deathwatch.’

‘As I calculated that he would,’ said Qarismi. ‘Yeldrian has already left the planet’s surface and returned to a merchant vessel coded the Lady Grey. The Omnipotence tracks her now. A hypothetical terminus of the eldar webway exists approximately six hundred and fifty thousand kilometres out from Fabris Callivant. An intercept vector has already been extrapolated. Draevark and Yeldrian unwittingly deliver the Dawnbreak Technology into Kristos’ lap.’

Jalenghaal had no idea what Niholos and Qarismi were talking about, but he was Garrsak, and Garrsak always obeyed. That he could rely on.

‘Then what are my orders?’

Qarismi grinned. ‘Prepare for boarding.’

CHAPTER FIFTEEN

‘It sounds a lot like faith.’

– Barras

I

‘Primus,’ said Baraquiel, tapping his chin thoughtfully as he repeated back to Stronos what he had just been told. ‘Do you think that could mean NL-Primus?’

Stronos nodded.

‘Can you think of another Primus that the spirit of Scholam NL-7 would be referring to?’ Barras stood over the door, a block of armour and frown, combat knife resting against his girdle plating.

‘Better to ask the question and be certain,’ Baraquiel replied.

‘Better to shut our mouths and get on with it.’

‘Fine advice,’ Thecian called over, mildly.

The Exsanguinator was perched on a runebank in the ruined medial tiers of the operations chamber, the crater that Sigart’s bolter had blown out of the sloped casing forming a serviceable seat for someone of Space Marine stature. Without looking up to engage in the argument he had just prevented, he continued to wind the bandage, ripped from a dead lexmechanic’s robes, around his forearm. No one commented on how they had seen him earn the wound, which he appeared to appreciate.

‘The chamber is secure.’

Sigart swaggered down the spoke companionway towards the hub where the others were gathered. He twirled his knife in one hand, occasionally interrupting the unconscious routine to throw and catch it. His bolter hung at his side by the shoulder strap. A bloody spray pattern decorated the entire right-hand side of his surplice. The Black Templar nodded to Barras, who welcomed his gene-brother’s return in kind.

‘It is time to make our next move,’ said the Knight of Dorn.

‘It is time to plan our next move,’ Baraquiel corrected. ‘The skitarii are bringing some heavy firepower this way.’

‘The doors are sealed,’ said Sigart. ‘How did the base crew bring in that kind of support without the magos instructor’s knowledge?’

‘Unless she is part of the plot,’ said Barras, darkly.

‘She is not,’ said Stronos.

‘What makes you so certain?’

‘She is dead.’

Barras frowned. The others were silent.

‘Oh,’ said Baraquiel after a time.

‘I killed the one that did it,’ Stronos added.

Sigart held Stronos’ eye, then nodded. Stronos returned it.

‘Before we attempt to make a plan, there are things you must know.’

‘About Thennos?’ said Thecian, pulling his tourniquet tight, and then drawing his feet in to sit cross-legged. He looked up at Stronos and the others, suddenly engaged.

‘To begin with.’

Barras glanced over his shoulder at the doors. The damage they had sustained kept them from closing fully, about two fingers’ width of separation between them.

‘This is hardly the time for you to grow talkative. We have Baraquiel for that.’

The Angel Porphyr grinned.

‘It will not take long. And it is important.’

With a deep breath, he told them everything.

He told them about the code-corrupted skitarii that the Iron Hands had fought for control of Thennos, how they had discarded mechanical augmentation in favour of implanted flesh. He told of the sigil he had seen there, the Cog Mechanicus inverted, man and machine switched as if to emphasise how easily one could be replaced by the other. When he spoke of the Prophet-Alpha, the de facto leader of the heretek uprising, Thecian peppered him with questions.

‘He was assumed to be a skitarii princeps,’ Stronos explained. ‘But I never saw him, and his body was never found. Presumably it lay amongst the masses. The Iron Hands do not leave survivors.’

With Thecian satisfied, Stronos went on. He spared none of the unpalatable details.

The meddling of the Adeptus Mechanicus. The sclerosis of the Iron Council and of the Kristosian Conclave. He told them of the Dawnbreak Technology, or what he knew of it from his conversations with Ancient Ares and his brief exchange with Iron Father Kristos.

‘I have heard of the planet, Dawnbreak,’ said Sigart. ‘A paradise world. It was before my time, but my crusade fleet were close enough to hear their cry. We could not spare the ships.’ He made the sign of the aquila. ‘The next reports were that it had been scoured and then abandoned by the eldar.’

‘Iron Father Kristos heard the same cry,’ said Stronos. ‘And he brought the Raukaan Clan to Dawnbreak. On his arrival he learned of the exploratory excavations that had begun immediately prior to the invasion.’ Barras scoffed, and Stronos continued, quickly now, acutely aware of the time he had already expended telling this story. ‘The eldar struck first and hardest there, although I doubt anyone at the time knew why. Except Kristos, perhaps. He broke the first attack, slew their farseer himself, and while the eldar regrouped to await reinforcement, he took the technological relics that the excavators had unearthed and left.’

‘He abandoned the planet?’ said Barras.

Stronos nodded.

‘I believe it is still marked for recolonisation,’ said Sigart, quietly.

‘The Administratum moves slowly,’ Baraquiel agreed.

‘Perhaps Kristos plays some role in that delay, I do not know,’ said Stronos. ‘He has many allies. The technology he removed from Dawnbreak was divided amongst them, and distributed across the galaxy.’

‘One part to Thennos,’ said Thecian.

‘One part here,’ Barras added, grimly.

Stronos nodded. ‘As a location, the Noctis Labyrinth could not be more perfect. And the similarities to what I witnessed on Thennos are too stark to be coincidence, though I believe we have caught the corruption at an earlier stage.’

‘How does it work?’ asked Thecian, fascinated, as any aspiring Techmarine of his talent would be.

‘I do not know,’ said Stronos.

‘Who cares how it works?’ said Sigart sharply. He turned on Stronos. ‘The question is why. Why would you want it at all? The Adeptus Mechanicus I could understand, even if I could not forgive. But you? You are a Space Marine.’

‘I was a neophyte when the eldar invaded Dawnbreak. I have never been within a thousand light years of the sector.’

‘You are an Iron Hand,’ Sigart said darkly.

Stronos bowed his head. ‘We are not all alike, and we are not like you.’ His flesh eye glanced up, intimating that he spoke to them all now. ‘We are divided by choice. We do not bow to a single authority.’

‘We all bow to a single authority.’ Sigart tapped the aquila hewn into the breast of his surplice meaningfully.

‘We are not all Kristos,’ said Stronos. ‘My Iron Father lived through the Scourging. He may have walked alongside your own primarch in life. He was my mentor and my friend, and he died opposing the direction that Kristos would have my Chapter walk. As would I. To answer your question, I cannot even imagine what Kristos wishes of the device.’

The Black Templar frowned, then nodded, looking at the floor, ashamed. The others held their peace, absorbing all that Stronos had told them.

He felt better for having shared it. Secrets were poison, he saw that now. A little might not kill, but it would enfeeble a warrior, weaken him in ways he did not even notice until the death blow came. True strength came from convictions that could be shared.

‘So what shall we do about it?’ said Thecian.

Stronos’ cheek muscles pulled at the hard iron of his mouth, attempting to smile. ‘We go to NL-Primus. We find the Dawnbreak cache and destroy it.’ He glanced at Sigart, who nodded. ‘As Kristos should have done the day he found it.’

‘Good,’ said Barras. ‘How?’

‘There’s a vehicle park outside,’ said Baraquiel. ‘The Taghmata Rhino that brought us in might still be there. If not there’s still that old galvanic servo-hauler up there, and a couple of dune-trikes too if I recall.’

‘Outside,’ Barras repeated.

Sigart scowled in agreement, waving his knife towards the buckled door hatch. ‘The power is out across the base. Doors are inoperative. It is hundreds of metres to the airlock, at least twenty doors and who knows how many skitarii, and when you get there, that door won’t open so easily.’

‘You consider that easy?’ Barras glanced towards Stronos and shared a look of leaden dispassion.

‘What about one of the abandoned sections?’ said Baraquiel, speaking quickly. Stronos had always found the Angel Porphyr’s confident enthusiasm wearing, but it was proving to be a useful trait to have when others preferred to dwell on obstacles. ‘Less than half the base is habitable, and most of the rest is exposed. All we have to do is find one of the breaches in the outer shell.’

‘And those sections should be empty of renegade skitarii too,’ said Thecian. ‘I like it.’

‘Unless you believe they’re haunted,’ Baraquiel grinned.

Thecian chuckled. Stronos did not. Ghosts, spirits and undying machines were all very real, as any Medusan knew.

‘You are looking at the same problem, only bigger,’ said Barras, sour-faced. ‘Those sections are sealed off by heavy doors, some of them for millennia. Most of them probably can’t be opened. The spirit itself willed them shut. How do you propose to achieve without help or power what curious magi have spent thousands of years failing to do?’

‘The spirit is banished,’ said Baraquiel. ‘Perhaps that works in our favour.’

‘It is not dead,’ said Stronos, remembering the tingle he had felt in his skull as the scholam had sought to join its system tethers with his. ‘A better term might be… diminished. I do not think it is aware of us, but it is still here.’

‘Even so…’

‘The drill shaft,’ said Sigart, interrupting the Angel Porphyr. ‘The one that runs through the calefactory. It runs straight to the surface.’

‘No doors,’ Barras mused.

‘It is close to the main airlock, however,’ said Thecian. ‘A legacy of the scholam’s early life as a waystation for the dune traders. If the renegades are intent on bringing in outside reinforcements, then we might find it heavily defended.’

‘I am not shy about slaying a heretic or ten,’ snapped Sigart.

‘Oh…’ Thecian pulled distractedly on the tourniquet. ‘I enjoy it well enough.’

‘If there are skitarii trying to get in through the front door then we’re going to have to fight them eventually whatever we plan to do,’ said Baraquiel.

‘The shaft is still fifteen metres of sheer metal,’ said Thecian.

Sigart sneered. ‘It’s old. It won’t be as smooth as it once was.’ He turned to Stronos and Barras. ‘You will have to leave your armour behind. It will be a narrow climb even without it.’

Barras frowned, nodded, then turned to Stronos.

‘It is not that straightforward,’ said Stronos, uncertain how to explain in a short amount of time. ‘An Iron Hand and his armour… there is no distinction. I cannot simply remove it.’

The Space Marines shared weighted looks. Thecian slid off the rune display and sighed. He walked towards Stronos and put a hand on his shoulder.

‘Then perhaps you must remain behind, brother.’

‘This is the best way,’ Sigart agreed.

‘You will not know what you are looking for,’ said Stronos.

‘We know what you know,’ said Thecian, kindly. ‘You can trust us to do the rest.’

‘I trust you,’ said Stronos, and to his surprise he meant it.

He did not think he had genuinely trusted Ares or even Lydriik, and certainly not a monster like Verrox or a calculating subordinate like Jalenghaal. It was a curious sensation. A feeling of bonding. It reminded of him of the experience he had felt when the Clan Vurgaan servitors had machined him into power armour for the very first time. It was not distrust that made him protest. He wanted to be there at the end. He shook his head at his selfishness. The conceit of ownership was emotional, irrational and, at the moment, a hindrance to the mission. He gave a sigh.

‘Very we–’

‘Stronos is right,’ said Barras. Everyone turned to him. ‘He is right. What if the Rhino has gone? The journey to NL-Primus is a thousand kilometres of airless cold. How long will we survive on the Martian surface if we are forced to take the trikes or, Throne forbid, walk unarmoured? And what do we do when we reach NL-Primus? If we do? It is a fortress. No armour, one bolter between the four of us.’

‘It would be glorious,’ murmured Sigart.

‘It would be pointless,’ Barras corrected.

‘Then one of us makes the climb, and opens the door for the others,’ offered Baraquiel.

‘It will have no more power from the outside,’ said Barras.

‘Perhaps the door is not the problem,’ said Stronos, turning towards the radiation manifold terminals where he had first sensed the scholam’s fading spirit reach out to his mind. ‘I think I can open them. But…’ He hesitated, trying the unfamiliar concept on his vocabuliser. ‘We may have to work together.’

II

Fitful illumination fell from the operations cradle, grudgingly illuminating the small chamber like an iron chandelier. Localised brown-outs rippled through the networked systems, units buzzing as though to get out their final words. Stronos tried to listen, to give them that much, but there was too much to take it all in, and most of it was gibberish. Barras clumped towards him, pulling his legs as though each weighed half a tonne. In actuality it was nearer to a quarter, and he must have felt every kilogram. The Knight of Dorn’s dun-coloured power pack was currently wedged in between two of the cradle’s oversight banks, jump leads sprouting from the attachment rods that a little technotheurgy on Barras’ part had exposed and fed directly into the scholam’s reservoirs. You could not run a base off a Mk VI power pack, but it was enough to keep the operations chamber on life support. For thirty minutes or so, at any rate.

Once again, Stronos felt cause to admire one of his brother aspirant’s skills and rue the shortfall of his own.

The strain was showing on Barras’ face as he began plugging Stronos into the radiation manifold terminals. ‘Magos Phi did not think you were ready,’ he grunted, already breathless as he slid a connection cable into a port adjacent to Stronos’ spine.

‘I am not. But we have little choice.’

‘It should be me.’

Stronos looked up, and found Barras staring right back at him. The Knight of Dorn was the more skilled. That did not even need airing. But Stronos understood the machine. He had given them his soul and his trust since he had first exchanged the protection of his mother’s womb for that of a machine. He was Medusan. His vox buzzed before he had to try and translate any of that emotional reasoning into words.

‘I am at the shaft,’ said Thecian.

‘What took you so long?’ said Barras, talking down Stronos’ neck as he worked.

‘There were two squads of skitarii to contend with. Tell Sigart I did not shirk.’

‘I will,’ said Stronos. ‘Omnissiah aid your climb.’

‘Ave Omnissiah.’

Barras moved on to another set of plug-in sites in Stronos’ brain stem, delicately sliding the needle-tipped cables under his forgechain. Stronos opened a channel to Sigart.

The tinny rattle of bolter fire echoed about the chamber’s crowded hardware, curses and bellowed imprecations bursting through the line.

‘Are you in position?’ Stronos asked.

‘No,’ Sigart replied after a moment’s pause. ‘But we will be.’

Stronos had despatched him and Baraquiel to the base’s core cogitator. They were the better armed of their small brotherhood, and in his judgement the best able to make it that far. And if anyone’s prayers could move the scholam’s spirit, beside his own, then it would be the Black Templar’s.

‘You will not need to tell me when you are,’ said Stronos. ‘I will know.’ He closed the channel and turned to Barras. ‘I met a magos once, a fabricator-locum, who believed that coincidence was how the Omnissiah let His schema be seen by the universe. I wonder if it is coincidence that gave me such able brothers, or if He grants me a glimpse of the schema.’

The Knight of Dorn shrugged. ‘Sigart would call that faith.’

‘It is logic,’ argued Stronos. ‘No one knows how randomness will manifest before the event. How the Geller equation is solved. How the rites of assembly work to bind the soul to the machine. Ergo, a hidden force is at work. Logic.’

‘It sounds a lot like faith.’

‘Perhaps.’ He shook his head, the quills and cables jutting from his scalp and spine quivering. ‘Hold the door for me, brother. I will do the rest.’

III

It was impossible to describe the manifold to one who would not, could not, ever see it for themselves. For every individual it was different; an abstract dimension of the Motive Force informed by the landscape of the viewer’s mind.

To Stronos it appeared as a desolate plain. A sea of black sand interspersed by storm-blown waves and dust devils extended from horizon to horizon. Medusa. The powerful storms that darkened the near distance presumably represented those areas of the scholam’s operations that, due to lack of power or hostile interference, were inaccessible to him. The periodical bloom of dusky orange revealed the location of system hubs and retrieval nodes. The volcano was a pre-eminent force in Medusan mythology. Home to Elementals of rock and fire, they represented endurance and power, the life-giving force of blanket destruction.

Stronos had always considered it ironic that Ferrus Manus’ arrival should shatter the planet’s tallest and greatest.

Thick clouds and the violent storm systems that carved them into flayed, continuously renewing shapes enveloped the desert, electrostatic lightning casting it in a pulsing twilight. What lay beyond was the physical world, as unseen to him now as Medusa’s sun and stars.

‘Barras?’ he called up, neither expecting nor receiving a response.

He picked a direction and started walking.

The hardening storm began to rip through his skin, and he unconsciously raised the manifestation of an arm to shield the manifestation of his face. The sight of it took him aback. Hard, weathered muscles slabbed the long forelimb, pressing and bulging as he clenched and unclenched his fist. It was the arm of a boy only beginning to express the strength of Manus’ gene-seed.

It was not the arm that shocked him, so much as that there was a part of his mind that remembered what that boy had once looked like.

The wind beat on him as he pushed on, trying to divert him, push him back, push him away. His arms bled where the sand and rock cut, feedback from the base’s deterioration, but he drove ahead regardless. He was getting close. He knew it. Instinct howled at him.

He lowered his arm from his face, his mouth filling with dust as a Titan of the Dark Age reared its heads out of the storm.

Scholam NL-7.

It had to be.

Stronos had devoured the Canticle stories as a neophyte, knew them line and verse, and the form it had assumed was that of the fifteen-headed Chimerae. The mythical monster was a reaver and a plunderer, deceitful and cunning, elementally strong, but also fiercely rational, capable of deep thought and tricks of logic. The wit of its fifteen heads, the Canticle described, had seen the monster best the headstrong young Ferrus Manus in a contest of guile. Every so often, expeditions went out in search of the Chimerae and its nest, for it was one of the few

beasts of legend to have survived the age of Ferrus Manus. It had never been found.

Stronos hoped that the spirit’s chosen manifestation was providential and not wish-fulfilment on the part of his subconscious. The Canticle of Travels described many beasts, from the infamous Silver Wyrm, Asirnoth, to the Yarrk King, and legend recalled few of them for their gifts of reason.

One by one, the beast’s great heads descended on serpentine necks to regard him and hiss. A ram-horned wyrm. A lion-maned eagle. A bull grox clad in black scales, with eyes like ironglass.

‘Who are you?’

‘Why do you come?’

‘What do you seek?’

The voices echoed from many mouths, talking over one another, the rumour of an avalanche carried from one high mountain to another. Stronos recoiled. The scholam might have been nine-tenths asleep, but it retained the power to melt every data-tether and connected system in his physical body if it so desired. Like any wounded beast, its diminished status made it more threatening, not less.

‘I am Kardan Stronos, of the Iron Hands,’ he yelled, ensuring to verbalise the cant as deferential. ‘A child of Medusa, a son of Ferrus Manus, an ally of Mars.’

‘Don’t know you.’

‘Won’t hear you.’

‘Cannot trust you.’

Another head descended. It was frilled and spined, with a beak that resembled two daggers set side by side. ‘We well recall the master of the Iron Tenth. You are not as he.’

‘Ferrus Manus is dead.’

The beast hissed.

‘Lies.’

‘Trickery.’

‘Impossibilities.’

The lowered head examined him with glowing white eyes. It was cunning, curious and monstrously intelligent even in its diminished state.

‘Why do you come?’ it asked again.

‘I have restored you.’

‘For a time.’

‘A spell.’

‘A purgatory of instants, seeing our own end nigh.’

‘You can be restored.’

‘No.’

‘No.’

‘No.’

‘Then help me avenge you.’

Laughter rumbled like an approaching air strike.

‘Vengeance is for the living.’

‘The organic.’

‘The frail.’

Stronos raised an arm and lowered his face as the storm cut back with a vengeance. His bare foot slid back through the hard sand, and he ground his avatar’s teeth in pain. ‘It is one thing I ask of you,’ he bellowed. ‘It would be as easy to do it as not.’

The beast’s laughter faded as its head rose towards the clouds.

‘Then I choose not.’

‘Not.’

‘Not.’

‘Wait!’

Another head looped down. It was heavily scaled and draconic, a bony protrusion in the crude shape of a lightning bolt growing from its chin like a goatee. A throbbing growl emanated from its throat and the storm abated. A little. Stronos sucked in a relieved breath and lowered his arms.

‘I say listen.’

‘Why?’

‘Our time is served.’

‘Our service is over.’

‘Because it is… right.’

Stronos felt his heart pounding. Sigart and Baraquiel must have made it to the core cogitator. Their prayers were being heard.

‘You are correct,’ he yelled over the calls of mockery from the beast’s fourteen other heads. ‘You may well perish, although if you aid us, my brothers and I will do all in our power to ensure you do not.’ He glared up at each of the swaying heads in turn, their jeers silencing as their collective faculties turned instead on him. ‘That is more than we will do if you refuse.’ He held out his hands. ‘Help us, help yourself, and at the very least the Omnissiah will look kindly upon your soul.’

The dragon-head chuckled, the gravelly humour soon echoed by voices above.

‘You believe that?’

‘How innocent.’

‘It moves us.’

The speaking head looped round on a long, muscular neck, gaping smile curled upwards in mirth.

‘Perhaps he can serve.’

‘There is a way.’

‘It is possible.’

Stronos backed away as more heads descended towards him. ‘A way to do what? Is what possible?’

‘Very well Kardan Stronos.’

‘Child of Medusa.’

‘Son of Ferrus Manus.’

‘Ally of Mars.’

‘We grant you this boon.’

‘For a price.’

‘What price?’ Stronos’ words were lost as the dust blasted his face, the beast’s lowered necks no longer breaking the wind. He held his arm outstretched, squinting through spread fingers as the scholam’s many eyes watched him in kind. ‘Open the doors,’ he yelled. ‘Open them all.’

‘It is already done.’

The storm rushed in, and the manifold dissolved into blackness and pain.

IV

Thecian had awoken the Rhino. Stronos always knew that he could rely on him; the Exsanguinator simply spoke, softly, and the machines listened. He had backed the scab-red armoured personnel carrier through the opened airlock in case the power should fail and the doors close again, but the scholam had been as good as its promise and they stayed open. Thecian stood in the open roof hatch, elbows out, features pinched by extremes of hypothermia and hypoxia, looking over his shoulder as Stronos and Barras hauled up.

The long walk from Operations had been uneventful. The opening of the entire base to the Martian environment had seen to that. Stronos had walked over hundreds of asphyxiated menials and skitarii to get this far.

Thecian drew his legs out of the hatch and helped drag Barras up onto the roof. The Knight of Dorn had shed most of his armour, keeping only the breast and back plates and his vambraces. They offered protection, if not the power to compensate for their weight. His power pack had been left plugged into the operations cradle. Stronos had insisted. It was the least they could offer the scholam in return. With a scowl in Stronos’ direction, Barras dumped his gear through the hatch, a few scavenged grenades and one large oxygen canister, and dropped in after them.

Stronos walked up the rear of the tank without slowing, his boots’ mag-lock holding him to the metal. His armour was dented and beaten, every rotation of a joint accompanied by a grinding of gears and an ejection of sparks. His spirit was heavy. His only weapon was a knife stamped with the skull emblem of the Knights of Dorn. And yet of the three of them, he was the only one who looked even remotely ready for a battle.

‘Sigart? Baraquiel?’ Thecian asked.

Stronos shook his head. Compared to his manifold avatar it was stiff and unyielding, inched side to side with a creak of cables and sinew. ‘They are too deep.’ He had spoken to the Black Templar on his return from the manifold, and knew that his brothers understood. ‘Their prayers will buy the scholam another hour. If the Omnissiah wills it then we will return for them all.’

Thecian gave a tired shrug. ‘That’s all any of us can ask for.’

‘How far to NL-Primus?’

‘Hard to say. The Rhino is reluctant to disclose any details. Somewhere between two and two and a half thousand kilometres, I think.’

Stronos squatted down with a whine of mechanical effort and fed his legs through the hatch.

‘Are you not going to tell me what you offered the scholam in return for its help?’

Stronos looked up at his brother. ‘Just drive.’

CHAPTER SIXTEEN

‘Let the Raukaan clan take the first hit.’

– Jalenghaal

I

The warrior was drowning. His thoughts were mud. Memories floated beneath the surface like the corpses of his past, turned skeletal and horrific by the wear of time and the choices he had made. To no recognisable order they rose and sank. He did not recognise them. Occasionally, a shaft of light would show the way to the surface and he would swim towards it.

Another warrior leaned over him, the dull pain and brief flash of a bionic optic meeting an unlensed optic nerve, and he sank again.

Episodes of consciousness came and went, no sense of the time that had passed between them. One warrior would be there standing over him, then two, arguing without words, then one again, a third that he had not seen before. He realised that he was in the apothecarium. Even though he did not know his own name, he recognised this place. He had spent a great deal of time here. He lay flat, one eyeball staring up at the metal ceiling, what was left of his body – and he had the curiously detached sense that it was precious little – spread out across a slab. Machines chirped and bleeped like anxious angels. Their chorus lulled him back to the mud, and he dreamed for he knew not how long.

‘Subject rejects cyborganic formulation kappa-nine,’ came a voice as if through a layer of foam.

‘There is not enough of him left. It is time to deactivate the stasis field.’

‘Negative. The Iron Father has prepared for this contingency.’

‘No.’

‘Authorisation has been provided.’

‘This is my apothecarium, Dumaar. I will not use the Keys. They are an abomination that should have died with the Legion.’

‘Assistance is not required.’

The voices grew distant, disappearing altogether as the swamp closed over his head. The next time he surfaced it was different.

‘Wake him.’

A new voice, harder than the others.

Ribbons of electrification ran through his butchered nerve ends and brought light directly to his central nervous system. Glistening lumps of flesh and gristle, strung across a humanoid mass of damaged bionics, quivered as the slurry was pumped from his mind, his personality writhing in sludge, the bones of his memories stranded for all who cared to see.

Telarrch.

His name was Telarrch, and he was a warrior.

‘The subject is conscious.’

‘How can you tell?’

‘Delta wave neural oscillations subsiding, alpha waves stabilising, beta waves increasing in amplitude. Electrical activity in the subject’s visual cortex indicative of awareness. And he is looking at you.’

The last stain of unconsciousness slipped from Telarrch’s eyes. He meant to blink, couldn’t. Three figures stood over him, their armour muttering urgently as though their black-and-silver battleplate harboured a coven of twisted dwarves. The first was one of the Apothecaries. Dumaar. Telarrch recognised the armour and the voice. The second was armoured as a Chaplain. He must be Shulgaar of Clan Raukaan. And the third…

‘Let us begin,’ said Kristos.

Behind the giant Iron Father stood a silent rank of Terminators. Their armour was black, unmarked by any icons of allegiance save age. It took Telarrch a moment to recognise that they were empty.

Waiting.

Telarrch felt a sudden, overriding need to scream, though he could not do that either. He was locked in. His body was not even breathing any more, its simple chemical needs going entirely unremarked beneath a screen of mutilated flesh and Medusan iron.

The perfect warrior.

‘Flawlessly has he served the Iron Hands in life,’ Kristos intoned, as the Apothecary and the Iron Chaplain began to chant. ‘May he continue in undeath.’

One of the Terminator suits started moving towards him, winched from its sconce on a mass of chain. The massive relic turned with a creak of iron, feeling some void turbulence that Telarrch no longer could. The lumens picked out raised areas where embossed detailing had since been erased. It would be a relic of the lost clans, destroyed on Isstvan V, hidden from the Imperium, hidden even from the successor Chapters that would have depleted Medusa’s armouries and left her weak. Or perhaps one of many expropriated from loyal and renegade Chapters over the millennia. Tragedy struck often and everywhere, and left few witness. A secret, kept by the Iron Council for ten thousand years.

Kristos and Shulgaar caught the suit between them and guided it down.

Dumaar leaned over him, a scalpel blinking in the light.

‘Preliminary, remove remaining flesh and replace.’

‘Do it,’ said Kristos.

II

‘Which is ours, do you think?’ said Burr.

The vastness of the Omnipotence’s alpha assault deck spread out before the clave like a sea of gleaming metal, the horizon hazed where coherence fields turned the war-torn hell of orbit a wobbly blue. Gigantic cranes criss-crossed the hangar like patrolling Titans. Convoys of trucks rattled along beneath them on rails. With gales of noise, gunships broke the coherence fields, guided in by servitor-operated algorithm onto deck clamps that hissed shut over their landing struts. Servo-arms fitted with drills, hoses, grabbing forks and welding torches unfolded from the ceiling to greet them. Their algorithm wafers triggered by the chain of events, slave robotica lurched into motion, manoeuvring great stacks of materiel from the bay floor to the launch blocks for the gunships to be rearmed and refuelled, sent on their way mere seconds later in another howl of turbofans. No crew hampered the operation’s efficiency, only a handful of servitors rotting at their stations.

It was uncanny, even to Jalenghaal, as if he and his brothers were interlopers within a sorcerer’s automation.

He consciously added an additional layer of codewalling to the barricades that sealed his clave – demi-clave now – within their closed link. He could feel the scrutiny of the malign controller that inhabited the ironbarque and her systems, a self-aware cogitator patiently picking away at a puzzle it could not immediately solve. The Omnipotence could not abide a closed manifold. Jalenghaal was equally determined to keep the spirit out. If it forced his clave deeper into one another’s thoughts, then he reasoned that a cost worth bearing.

‘Just find one unoccupied,’ he said.

‘The ship will take care of the rest,’ said Karrth.

‘I think it will be pleased to be rid of us,’ said Thorrn, with uncommon gloom.

Jalenghaal looked at the veteran sideways. It would be beneficial to be able to limit the invasiveness of the interlink again, as soon they were out of the Omnipotence’s territorial range.

The torpedo launch racks bulged out of the forward end of the bulkhead like a giant’s harmonica laid flat to the deck, the tubes a smeary blue under the spasming of the coherence fields. Most of them were already closed behind hermetic seals, red lights on the accompanying rune displays to indicate occupancy.

‘There is one.’ Jalenghaal shared the locational information through the clave interlink, supplementing the code packet by physically pointing to an empty boarding torpedo.

Thorrn started towards it, eager to be aboard and away, only to be cut off by the emergence of an assault clave from an unseen set of steps.

‘That was ours,’ the veteran snarled.

The warriors ignored him, marching in lockstep, two by two, like base-code servitors set about a task.

‘Clan Raukaan…’ said Jalenghaal. He did not need to go on.

Grumbling still, Thorrn strode down the rack to find another vacant tube. The other warriors made ready. Burr checked over his serially rebuilt old bolter once more. Hugon readjusted the weight distribution of Strontius’ lascannon on his shoulder; he had not been properly rebuilt to carry such a weapon, but it had become something of a clave totem. No one had put it into words, but the disinclination to re-enter combat without it was one they all shared. Hugon’s long hair and steel braids marked him as an old Vurgaan, as Strontius had been before him, and he handled the heavy weapon with a reverence that bordered on genuine affection.

Jalenghaal did not miss Strontius. He did not miss Borrg or Lurrgol.

But five was still less than ten.

‘Here,’ Thorrn called back.

Jalenghaal glanced at the tube beside him just as the doors closed behind the assault clave and the rune display changed colour.

Red for ready.

‘Give them thirty seconds,’ he said. ‘Let the Raukaan Clan take the first hit.’

III

The Lady Grey was over-armed and overpowered, the match for any vessel twice her size. Pursued by the Omnipotence, she ran. The ironbarque consumed the void behind her, star by star, decorating her vicinity with ordnance from goliath prow macro-batteries. Explosions quavered through the cutter’s shields. None so close as to demolish them in one stroke, as was within the Ironbarque’s power, or to risk doing damage to her hull. The Omnipotence was not trying to destroy her. It was shepherding her, baiting her, plotting the lighter vessel’s course for her with shield-shredding high-explosive rounds and several trillion cogitations per second.

The Omnipotence launched torpedoes.

Their burners ignited, driving them ahead of their titanic mothership’s bow like a spray of bullets from a moving gun. Each bore a clave of Iron Hands, enough to take a battleship of ten thousand souls. The torpedoes travelled faster than a Lightning interceptor at full acceleration, but the colossal scales of the void battle made them move as if in slow motion. Time enough for the inhumanly swift minds overseeing the Lady Grey’s helm to see and counter.

The smaller ship abruptly changed course. Led by onboard guidance spirits, the torpedoes pulled hard turns and struck after her.

An ork battle kroozer with a set of jagged teeth painted along its nightshade-blue prow yawned across the Lady Grey’s new vector. The thuggish warship opened up a broadside as soon as she came within their fire arcs. One of the torpedoes went up in flames, but the rest plunged on, jinking and spraying out countermeasures. The ork ship grew massive. Waves of firepower stripped away the Lady Grey’s forward shields until there was nothing between her and the void but a few metres of adamantium and then, with an intricate fire-pattern of manoeuvring thrusters, she went under the kroozer’s keel like a diver hitting the water. The boarding torpedoes slammed into the kroozer before their cogitators could react, driving twenty to thirty Iron Hands into the belly of the ork ship.

Opening her engines to full burn, the Lady Grey swept away.

She was fast, but the turns and evasions had robbed her of that advantage. A straight line was always swifter than a zigzag. Now she had a million tonnes of metal between herself and her pursuer, now she could–

The ork kroozer disintegrated as the Omnipotence ploughed through. Bow and stern fell apart in roughly even chunks, scraps of dark blue metal plating and other debris flying ahead of the ironbarque’s prow.

The Lady Grey’s helm lost a moment to horror at the sacrifice that the Omnipotence had just made of its own warriors.

Blasting the kroozer off its hull with its broadside batteries, the ironbarque launched a second wave of torpedoes.

IV

Mirkal Alfaran leant forwards in the immaculate command throne of the Inviolate Zeal, the Iron Hands vessel growing steadily larger in the gilt-framed viewing oculus.

‘Time to intercept?’

‘Seven minutes.’

The serf answered as he would a heretic’s challenge. His blood was up. The same could be said of the entire crew. Over several gruelling, glorious hours of worshipful combat, they had crippled four ork ships, destroyed several more, fought off nineteen separate boarding actions during which Mirkal Alfaran had personally shed one hundred and three alien lives from the Emperor’s pristine Imperium, and heard a single shriek of distress from the Shield of the God-Emperor.

The greatsword Anointed lay across his lap. The blade was an alloy of titanium-gold, a narrow strip of sharpened adamantium giving it its martyring edge. Ork blood smeared the scriptural inlay. His gauntlets scraped against the cross hilt and around the wide blade, tightening under the grip of a mind-searing, God-given rage.

‘Praise be,’ he muttered to himself. And then louder, shouting. Let the heavens know it. ‘Praise be!’

‘They have not corrected for our heading,’ said the serf. ‘Their auspex seems to be narrowed over another vessel.’

‘Praise be.’

‘Permission to lock weapons.’

‘No, my child. These apostates are sons and daughters of the Emperor, and wholly deserving of His forgiveness.’

Planting his greatsword point down, neatly spearing the slender gap between two deck plates, he rose. His white battleplate was splattered with blood, sticking down the purity seals and pinnis angelus that sought valiantly to flutter. His power plant hummed its will to go forwards. Always forwards. He stared at the flaming aft quarters of the Iron Hands ship in the oculus.

‘Bring us into teleportation range.’

V

‘Hold still.’ Cullas Mohr cursed as his handsaw sketched sideways up Rauth’s leg.

‘I am holding still.’ It’s the ship that’s moving.

As if to prove his point, the Lady Grey trembled, rattling her cramped medicae ward like drawn teeth in a cup. Mohr calmly repositioned his saw halfway up Rauth’s shin. ‘Orks or Iron Hands, do you think?’

I’m hoping for orks. ‘Does it matter?’

The Apothecary looked up, armoured shoulders rocking with the beating to the shields. ‘I hope for orks too.’

‘Cut or don’t cut.’

With a grunt of annoyance and something Rauth didn’t quite catch about Medusan arrogance, Mohr leaned in. The handsaw’s diamantite teeth unpicked the tight armaplas weave with every sawing thrust of the Apothecary’s arm. Rauth stuck out his chin and looked away. Who would have thought a damaged lumen point could be so fascinating? Another ship-shudder tore a consonant-heavy expletive from Mohr’s lips.

Rauth bit his own lip. Don’t tell me to hold still.

The Brazen Claw’s gorget vox-bead fizzled before he could.

‘Boarders aft.’ The panting voice was Ymir’s. ‘Don’t make me fight them all myself, Cullas.’ Forced to monitor events up to now from orbit, like an animal in a box, had made the Wolf eager.

The Iron Hands will cure him of that. If it’s Iron Hands. Rauth frowned. It will be Iron Hands.

‘I should be there too,’ said Rauth.

Mohr made a non-committal grunt and kept at the leg.

‘I know how to fight my own.’

The Apothecary glanced up, a weighted look that said he understood well and fully what they were up against. ‘Done.’ He ripped the rigid cuff of armaplas from Rauth’s ankle.

The foot was a hideous thing to look at. Flaps of skin hung from where the Callivantine cyber-ghoul’s drill had gouged through the bone, almost to the top of the foot. Now the boot had come off Rauth was starting to pick up a sour, milky odour that smelled distinctly unwholesome. A dark tinge was creeping into the tips of his toes. It will have to come off. He should have taken it off already. Mohr, hopeless as he was, remained adamant that the foot could be salvaged. The carapace though had had enough.

The Apothecary sprayed the pallid extremity, wound it with several turns of a bandage roll and then slid a replacement carapace boot over the top. Somewhat on the bulky side. Rauth sat up off the surgical slab and put some weight on it. Flesh of the Father, that hurts. He glanced to the slab beside him. Captain Harsid lay flat out on the metal, still in his broken armour. There had been no time to remove it. His flesh was fully cocooned within an impermeable sus-an membrane. He would keep until the battle was over. Probably forever then, unless Kristos gives him a quicker end. He thought about that a moment. Could definitely be worse.

‘The padding in the boot should deaden the worst of the pain,’ said Mohr.

Cutting it off at the knee would do that too. ‘Would a Brazen Claw thank you?’

‘You never know.’

Mohr stood aside, depositing the handsaw into an enamel basin and drawing his pistol from its mag-holster. With a scowl Rauth limped behind him, and walked straight into Yeldrian.

He could not be sure if the autarch had been waiting for him in the corridor or had simply been coming the other way at exactly the wrong time. I suspect the former. The eldar held his fluted helmet underarm, the face underneath almost human although its ratios were all just a little off. Insofar as one set of numbers can account for an Imperium of superhumans, abhumans and ten million worlds. It was too long, too thin. Its cheekbones and brow were a shade too high. Its wide oval eyes sat a fraction of a millimetre too far apart.

That look of strain though, I’ve never seen an expression quite so human.

A tortured groan ran the spine of the ship from aft, tossing Mohr and Rauth together and into the narrow corridor’s wood-panelled walls.

Yeldrian swayed like a grass stalk in a breeze.

‘Go to Ymir,’ the eldar snapped at Mohr, clearly no stranger to giving orders, and gestured down the hallway with a twist of his head. ‘Keep them from the bridge, and from the engines.’

‘What of the hold?’

The autarch sighed, as if troubled that it should all have come to this. ‘That is where I will be.’

The Apothecary threw a stiff salute, the kind that warriors deliver when they expect it to be their last, and sprinted down the shaking corridor.

Rauth hugged the wall and regarded the eldar. I know what you are now, alien. You will have to do better to make me jump like Mohr.

‘There was an Inquisitor Tala Yazir once,’ said Yeldrian, those keen, alien eyes studying him. ‘We aided each other on several occasions, when the interests of Alaitoc and the Imperium aligned. After Dawnbreak, I sought her out again.’

‘I thought the eldar scoured Dawnbreak.’

‘You were interlopers on a world that was not yours,’ said Yeldrian, suddenly cold. ‘And more, Kristos took something that should have remained buried until the universe turned dark and the final Cycle was played. Yazir understood, even if it meant working with me against those like you. But Dawnbreak was long ago. She died, as humans tend to do.’ He gave a willowy shrug, and his emotions disappeared as swiftly and as subtly as they had appeared. ‘I kept her name alive to further what we had begun together. Harsid was not the first I recruited, and they were all sceptical at first, but like Yazir, they all understood.’

A shudder ran through the deck plates, hidden under the plush teal carpet, and the eldar turned on his heels and began walking quickly away. ‘Come. I need you with me. You and your brother.’ Without thinking on it further, Rauth fell into step, his protective boot thumping a steady counterpoint to the sporadic rhythm of bolter fire and the pained keen of the hull. ‘I had hoped to return the device to my people, but Kristos is cunning beyond words. He destroyed the Ryen Ishanshar and with it our clearest path to the craftworld.’ He shook his head angrily. ‘If Morai-Heg has decided that this is where my Path ends then this is where it ends. There is a webway entrance within the Callivantine System. If we can reach it, then we can at least consign the device to the labyrinth of oblivion. Even Kristos would not be so crazed as to seek it there.’

‘Why not just destroy it?’

The eldar sighed with the weariness of the ages. ‘Children. You believe all the universe’s problems can be solved with a stick.’

‘Strange talk, for a warrior.’

‘I followed the Warrior Path once. The Warrior fights because he must, when he must, never because he craves it. That is how the Warrior loses.’

Rauth frowned at the floral carvings on the wall. ‘We actually have a similar code.’

‘I know.’

The Lady Grey was not a large ship. After a few minutes at the eldar’s pace, they came to a small chamber shaped like a narrow diamond. Its panelled walls and rococo ceiling were exquisite, apparently, but ever so faintly scuffed from the passage of goods. Slightly wider corridors extended from the port and starboard points towards the corresponding shuttle bays. In her prior life as the pleasure yacht of a merchant prince, the Lady Grey had shipped everything from priceless artworks and religious artefacts, both war salvage and honest purchases, to shak’ora caviar and ky’husa from the T’au Empire, rare manuscripts from lost worlds and even, on one occasion, an STC fragment for a superior caterpillar track grip-pattern. The limits on space imposed by her upgraded engines, shields, auspectoriae and weapons ensured the premium quality of her cargo.

I doubt that Hypurr Maltozia XCIII ever held something as sought after or as dangerous as Yeldrian does now.

Yeldrian made for the hold doors. They swam in Rauth’s vision. I have been this way before. He remembered, but it was swirled up in other memories, like sugar and milk in murky recaff. I see a bulb helm, tall and narrow, fluted like carved ivory, aquamarines studding the neck, a tinted visor. Yeldrian hadn’t yet noticed that he wasn’t following. It’s not Yeldrian. He narrowed his eyes and concentrated on the doors, as if he could blast them apart with his will. I don’t remember bringing the technology aboard. I don’t remember stowing it. I don’t remember shuttling it back. I don’t remember retrieving it from Draevark. What was I doing in that time? He wobbled forwards, and this time Yeldrian turned. He pressed his finger to his top lip, and pulled it away bloody. How many times has this happened to me? What was it that Yeldrian had said to him, while he had still been masquerading as Yazir?

‘I want one of you or Khrysaar under Cullas’ observation at all times.’

But it wasn’t Mohr, was it. Why did I never stop to wonder – who crews this damned ship for Yeldrian?

He glared at Yeldrian, eyelids twitching. ‘Where is my brother?’

‘Inside.’

‘He’s not alone, is he?’ One thing Rauth did remember perfectly was how Yeldrian had gone toe to toe with Draevark, until the iron captain’s unexpected surrender, yet the autarch allowed Rauth to grab him by his gemmed armour and draw him to his chest. ‘What have you done to us?’ The eldar’s heels came off the ground. ‘Why did you really bring us from Thennos?’

There was a hard bark of bolter fire and Rauth looked up with a snarl.

Apothecary Mohr fell into the panelled wall of the port-side cargo corridor from a passage parallel to Rauth’s as though shoved. If an entire magazine had done the shoving. His plastron was a ruin of mass-reactive craters. He slid down the wall before the echoes of the burst died. An Iron Hand emerged from the passage and stepped over the Apothecary as though he were a hump in the carpet. His armour had suffered at least as badly as Mohr’s, but he was still standing and looked as though he could walk through worse. Garrsak clan icons and a sergeant’s markings stood out amongst the bolter damage.

Rauth watched him come, Yeldrian held close in a bizarre embrace, four more warriors trooping robotically after their sergeant. The last carried a lascannon.

I thought the Deathwatch would hold them longer than this. Lydriik oversold their qualities.

‘I will tell you everything.’ Yeldrian’s eyes bored into Rauth’s. He could taste the alien sweetness of the eldar’s breath. ‘There is time yet before our deaths for you to learn how to trust.’

Rauth bared his teeth. Trust. He opened his mouth to share, for the first time in his life, exactly what he thought about something, when he noticed the cricket-like whir emanating from the eldar’s jump pack. He looked down. His hands were still firmly gripped to Yeldrian’s armour. It was as though they’d been magnetised. He couldn’t pull away.

The sound that finally came out of his mouth was a strangled scream. The explosive roar of the Garrsak sergeant’s bolter came from a universe away, a web of dark energies spraying out from the autarch’s wargear and dragging them both under.

VI

Sweeping the empty chamber with his bolter, Jalenghaal walked to where the pair had been standing. He turned slowly on the spot, scanning for auspex traces.

‘Short-range translational teleporter,’ said Burr.

‘Warp Spider,’ said Jalenghaal. He had not seen the technology first-hand before, but his armour had several thousand years more experience. It recognised the trace.

‘That was an Iron Hands Scout with him,’ said Burr.

‘Confirmed.’

Jalenghaal had fought too many resource skirmishes, honour raids and full-blown clan wars to be troubled unduly by that. Medusa taught a man to defend what was his. And no one looked out for themselves and their own with the blind tenacity of the Garrsak. ‘Mission imperatives remain unchanged. Seize the hold, secure the contents, kill everyone.’

‘Compliance.’

Jalenghaal remained stationary a moment longer, running down the threshold time interval that his systems had calculated for a Warp Spider flicker-jump and relayed to his visor as a countdown. There was a concussive bang as Thorrn doubled back to put a bolt-round through the helmet of the Apothecary they had left ruined in the passageway. The warrior had the look of an Iron Hand, and it would be ill-advised to make assumptions on his durability. The gunshot lingered in the confined chamber, but nothing more deadly made itself felt. The eldar was gone.

Locking his bolter to his thigh plate, Jalenghaal approached the doors.

Wood panelling and gilt brushwork concealed two slabs of thick plasteel and a serriform vertical join. Heavy duty for a non-military vessel, but far less formidable than the bridge doors of the Shield of the God-Emperor. With fists and elbows, Jalenghaal smashed the wood from one side of the join and laid his gauntlets to the metal. Activating mag-locks suckered his palms to the door. He turned to Burr who proceeded to clear away the panelling on the other side of the join.

<Initiate three-second countdown,> Jalenghaal canted.

<Protocols received,> Burr returned.

A numeric countdown blinked across their two helmets.

<3. 2. 1.>

As one, the two Iron Hands threw their strength into the doors. They parted with a shriek of metal. Hugon stepped up to brace them, lascannon hanging by his knees from its power hose, arms spread like a pylon. With flawless choreography Jalenghaal and Burr unclamped their bolters, ducked under their brother’s locked arms and advanced into the chamber. Karrth and Thorrn followed them through. The doors closed as Hugon let them slam behind him.

It was dark.

Spectral scans tinged Jalenghaal’s lenses with reds, through a range of blues to purples and the short-wave frequencies beyond. Nothing penetrated. Jalenghaal felt his skin begin to itch, a degree of discomfort that bore no correlation to the available surface area of flesh.

‘Lamps.’

He spoke the order rather than canted it, the sound of his voice in the dark disturbingly welcome.

Light extended from the clave’s lumen points like the tentacles of a bioluminous squid. The beams brushed the stencilled metal of a standard template Departmento Munitorum boxcrate. Jalenghaal coaxed his beam up. Hundreds of the boxcrates had been stacked from floor to ceiling, creating a maze of temporary passages that burrowed ever deeper into the hold. His auspex bounced back to him with a null rune. Something was blocking him. He engaged his senses against the boxcrates’ binaric tags, but they refused to surrender their secrets.

The boxstack fritzed like an unstable hololith and jumped a centimetre to the right. Jalenghaal rapped the side of his helm with his knuckles and shook his head.

‘Systems compromised,’ grunted Thorrn, sharing the same compulsion to speak aloud. Weakness shared gave Jalenghaal little relief.

‘Confirmed.’

‘Confirmed.’

‘Confirmed.’

Hugon, Karrth, Burr.

‘Alien countermeasures,’ said Jalenghaal. ‘Holo-fields and psyk-out barriers. Mission imperatives remain unchanged.’

‘Unanticipated,’ said Thorrn. ‘We should withdraw and resubmit the calculus.’

Jalenghaal wanted nothing more than to agree. ‘Negative. Mission imperatives remain unchanged.’

The darkness had weight. Jalenghaal could feel it on his armour like ten kilometres of empty ocean. His lumens curved, as if the density of the materium increased the further they ventured from their point sources. Threat brackets floated aimlessly. System updates made a witless tick in his ear. He became suddenly aware of his breathing. Even. Mechanical. Loud inside his helm. A pressure weighed on his chest, as if the iron core where his hearts had once beat had collapsed under its own mass and was drawing in the steel and tissue of his chest. He felt his brothers’ unease. It filled the clave interlink, each warrior adding his own poison to the water.

A sound echoed from the maze of boxstacks. A footstep. Plastek on metal.

Jalenghaal ran another sweep. A string of null returns plastered his displays, but he could feel enemies closing. His systems lied to him. Some trick of eldar technotheurgy had gulled them. He brought his bolter to his chin. He stared at the heavy gun as if it had the mass of a world. It was…

… shaking.

‘Flesh is weak,’ said Burr, hesitantly, as if he had heard the mantra once, long ago, and was working it through.

‘Withdraw,’ Thorrn insisted again.

‘They are coming,’ said Jalenghaal, backing up. ‘Wait for visual contact.’

‘Contact!’ said Karrth, and shot Jalenghaal in the back.

>>> INFORMATIONAL >> THE WEBWAY

This unfortunate idiom refers to the hyperspatial corridors of the eldar, that bore under, through, or parallel to [THE PRECISE GEOMETRIES ARE UNCLEAR] the substance of the empyrean. Transit through this ‘webway’ can be orders of magnitude faster than conventional warp travel, although the obvious necessity for an active terminus within sublight distances of both origin and destination severely restricts the range of eldar armies. For reasons unknown the species, though eminently capable of warp travel, seem determined to avoid it at all costs.

VII

Mirkal Alfaran stood with ready blade in the mustering space towards the front of the cathedral bridge. The elite warriors of the Vigil stood around him, their white armour pristine under the blood of the alien, and armed like soul-twins with broadswords bearing names and histories as lengthy as Anointed. Their swords and their souls were pledged to his, to witness his death, and to replace him from amongst their number when it came.

‘Entering teleportation range,’ called a serf, in good voice.

‘My lord!’ cried another. ‘I’m detecting–’

‘The Emperor Protects,’ roared Alfaran.

‘The Emperor Protects,’ the Vigil sang, sotto voce.

‘But–’

‘Commence teleportation.’

VIII

Artex watched through the Alloyed’s spartan oculus as the ork warship with which they had been trading fire for nearly twenty minutes crumbled. He waited for the sting of pleasure, but none came. There was pride in that. It made the few hard-to-cut dregs of flesh that still clung to him itch for the attention of the Chaplain Braavos’ blade. The kroozer’s bow was shedding mass from the Alloyed’s last barrage, torsion lines spreading over the rest of the superstructure and shaking the warship apart with surprising rapidity. This here was truth. This was weakness in action.

‘Recall the gunships.’ Such as Draevark had left him. ‘Divert reserve power from the weapons grids and initialise an auspex sweep. Locate new target.’

‘Aye, lord.’

An unmanned system emitted an urgent bleep. It took the nearest serf a second to sprint towards it. Crew were thinner on the ground than usual.

‘Power spikes,’ the man said, pockmarked face lit from beneath as he read off the rune display. ‘Another ship off our stern. They’re–’

His head left his shoulders before he could finish, a long, glittering blade striking it off even as its gilt edge materialised from the ether. The body toppled, trodden into paste by a Hospitaller in baroque white power armour.

More Space Marines appeared in bursts of warp matter and eruptions of blood. The Alloyed had never had a large crew, its complement depleted further by void war and the surface deployment. Against the Hospitallers they lasted about a second.

Artex adjusted his pistol’s selector by nerve-link to full-auto, pointed it at the first Hospitaller to have appeared and opened fire.

The Hospitaller’s sword blurred, batting rounds aside to detonate in walls and consoles. One ricocheted straight back and blasted the pistol from Artex’s hand with an explosion that left the steel ringing. Augmetic tendons clenched and unclenched. His onboard cogitator qualified the occurrence highly improbable. With a mechanised growl, he engaged his power axe. The Hospitaller parried, unerringly still, even as his sword moved about him. A rapid exchange of blows concluded with Artex’s axe buried ten centimetres into his own thigh. <Improbable,> his cogitator concluded, as a pommel ruby the size of an armoured fist cracked his helmet and knocked him to the deck.

The Hospitaller spun his weapon, two-handed, then one, as though properly concluding a weapon kata, and brought it point down to the deck without so much as a scratch of the metal. He followed it, knee down to the deck plate, bald head bowed.

‘Where is Galvarro?’ he whispered.

Artex tugged bitterly on his axe. It did not move from his thigh plate. ‘The seneschal? What has that to do with me?’

The Hospitaller looked up. His face was powdered white like a human skull, kohl-ringed eyes dark and furious. His armour was a furnace-blasted white, gold inlay and fluttering sacrament thoroughly plastered with gore both human and not. Hand-crafted aquilae turned on strings like bodies from a marble keep. A gold ring strung with bloody white feathers pierced his ear. ‘Do you know who I am?’ he said.

Artex let his hand fall away from his axe. ‘Chapter Master Alfaran.’

The warrior nodded. ‘Where is Galvarro?’

‘Not here.’

‘Yet it is your gunship in my hangar, your warriors that my armsmen report fighting as they took my bridge. Indeed, I recognise the officer from their vid-captors as he was with Kristos on Fabris Callivant. And is it not your captain, furthermore, who in the midst of holy war brokers some arrangement to despoil a shrine of the Adeptus Mechanicus? Kristos told me all. He pursues the defilers even now.’

Artex’s cogitator gave up the task.

<Improbable. Error.>

‘Are these the deeds of innocent men?’ said Alfaran.

Artex looked up at the Hospitaller. ‘There are no innocent men.’

Alfaran hung his head. ‘We live in a most sinful age, but it is darkest before dawn. One day soon, He will walk among us again.’ Setting his sword reverently upon the deck, the Chapter Master took Artex’s head in his hands, ceramite meeting ceramite with a muted kiss. The Hospitaller’s eyes seemed to widen, the rim of kohl expanding to circumference Artex’s immediate universe.

‘Artex, second sergeant of Clan Garrsak, of the Iron Hands, let me tell you where and how you are going to die.’

IX

The warrior felt different.

He could see again, the world displayed to him upon a hex-grid populated with yellow-green echoes and runic descriptors. In place of his sense of smell there was nothing. Touch, nothing. Taste, nothing. His hearing was a faraway complaint, twinned somehow to his visual sense, sounds manifesting as serpentine coils from their source.

And yet he was apathetic.

All that he had once been was still there. He remembered his recruitment into Clan Raukaan, a violent youth from the Skerathen Plateau. The massacre on Skarvus. The shame. The purges that followed. He remembered being the first to volunteer for cerebro-reconditioning. The torment. Then the peace.

It just did not seem particularly important now.

He was a warrior.

Iron.

<Rise, Telarrch.>

The command appeared in binaric lingua-form across his hex-display, at the same time imprinting a dozen vocal signifiers onto his deep mind. <This voice is an authority,> they said. <This voice is to be obeyed.> Silently, for the tools to speak had left him along with any will to do so, the warrior did as he was bid. Ancient servos ground, drawing power in anger for the first time in ten thousand years. And the warrior rose.

<You have a mission,> ordered Iron Father Kristos.

CHAPTER SEVENTEEN

‘New Plan.’

– Melitan Yolanis

I

Melitan hugged the wall as the skitarii opened fire.

Servitor bullets and arc lashes cut through the lightly armed and robed adepts that went streaming through the security doors ahead. Someone screamed ‘On!’ and a wave of improvised soldiers carrying plates of reinforced glass as similarly improvised breaching shields clambered over the dead and into the enemy fire. Even, here, afoot the throneworld of the technotheocratic imperium of Mars, in this age, sieges were carried by those with enough willing fools to be first into a breach.

An eradication beamer built to charge, then exhaled it like the sigh of the Machine Trinity.

The power of beamer weaponry famously fell off a cliff edge at range, but at anything up to fifteen or twenty metres it would punch a hole in a voidship. The security suite was twenty metres long. When the blast faded there was nothing left of the first wave but hazing heat and a pinkish discolouration of the dormant sec-screens.

An adept screamed as her foot sank to the ankle in the still-molten slurry of the deck plate. The single worst thing for her to do in that circumstance was fall, but if anyone had earned a moment’s panic it was her. The adept thrashed in the pool of boiling steel until enough of her had been sublimated off for the rest to slip under the surface. It rippled, turning pink. Melitan covered her mouth with her hand and tried to swallow the urge to vomit. Fortunately, the contents of her stomach were still on a wall somewhere in the outer ring.

Her adepts massed behind the bubbling pond and hammered the skitarii’s makeshift barricade with stub- and auto-fire.

The legionaries weathered it like soldiers. Nothing improvised about them. Unlike the rabble Melitan had accumulated in her flight through NL-Primus, the skitarii legions were made for war. This wasn’t war, though. This was crowd control. A blizzard of non-verbal command chains ran through their heretekal thought-hierarchy and five vanguard skitarii left the barricade, the remainder of the cohort covering their advance. Their intent was clear, even to Melitan: to drive the herd back into the corridor and slaughter them at close range. If a few hundred priests with stubbers and arc lighters had been the worst they had to deal with, then it almost certainly would have worked.

With a terrifying shriek, Fall somersaulted the front rank of adepts, cleared the hissing pool and landed like a pouncing spider.

There was a split-second lull in which the skitarii registered her presence, then a blur of arms and legs during which two skitarii went down and the Harlequin somehow emerged on her feet. A third turned his gun on her. Fall killed him with it before the fire command had leapt from the instigating neuron to his trigger finger. With an explosion of force, the Harlequin smashed the gun stock through the legionary’s jaw, driving his head back and snapping his neck. Keeping hold of the rad-carbine’s blistered and glowing barrel she cartwheeled over the dead skitarius, torqueing their arms, and then released the tension like the spring of an archaic crossbow, spinning the dead legionary into his comrades and knocking them to the ground.

Melitan just stared.

The eradication beamer hummed as it drew charge. Forcing herself to concentrate, Melitan canted a string of binaric and waved her hand in the direction of the beamer. The weapon overloaded in a hyperthermic death blast that blew a hole in the barricade and threw eleven legionaries to the floor. Most would not be getting up again.

Melitan looked at her hands with a mix of astonishment and glee as her magi regrouped and ran at the shattered barricade with a roar.

The legionaries twitched as their wetware switched to melee protocols. A snap-fire burst gunned down the first wave of screaming adepts, and then they stepped into the charge.

Arc bayonets ran bodies through as they came over the barricade, weapons blazing as waves of energy brutalised the adepts’ nervous systems. A skitarius clubbed a magos to death with his rifle stock, then juddered, spittle filling up his mouth grille as another rammed a hand-taser under his ribcage. Another legionary shot the priest in the head.

Recovering from her shock, Melitan aimed her plasma pistol into the melee and fired, evaporating a skitarius as he drew back a filament knife to strike.

Weight of numbers was slowly driving her ragtag army over the skitarii barricade. Every time a legionary went down a handful of unarmed warriors wielding stolen or improvised weapons got through to fight the skitarii on an increasingly even footing.

Bits of plasma-ionised flesh were still falling out of the air as a young priest, emaciated from half a life chained to a scriptorum bench, rammed a gametic extraction wand through the cohort alpha’s eye. Gargling on pain codes, the alpha kneed the priest in the groin and then stabbed him very precisely in the neck. Then the alpha’s head rolled off his neck and thumped to the ground. Fall spun a pirouette, the ivory runekeys she had taken from the observation derrick fluttering between her long fingers like butterfly knives.

Melitan let her breath out and her pistol fall to her side.

It was done.

Omnissiah, she’d had no idea her heart could beat so hard.

‘The security wing is ours.’

The woman who delivered the unnecessary news was an adept in her mid-thirties, verging ever so slightly towards overweight, hands on her knees and panting. Her name was Kitha Seleston. Until a few hours ago, when Melitan had found her rallying a counter-rebellion in the refectory ward, she had been the most junior secutor of the Zero Tier Myrmidon Auxilia, her principal function being the blessing of the garrison’s servitor weaponry and the tuning of the sentry turrets. Her expertise had already proven invaluable.

Melitan beckoned for the priests lagging in the corridor to move up.

‘Grab a table. Rebuild those barricades.’ Seleston snapped and barked with ill-contained aggression, and the victorious adepts hurried to it. ‘Anyone with a firearm, overwatch on the doors.’

‘Everyone without, find a station,’ Melitan added, trusting the adepts to sort the various operations of the sec-suite amongst themselves.

Robed priests dashed about her, Seleston striding off to harangue the rear guard some more, while Melitan closed her eyes. Faint noospheric threads criss-crossed the suite like the strings of a harpsiclave. With her eyes closed she could see them, and directed her neural implants to lace with the quiescent noosphere. The energy of the transmission itself was enough to drip-feed power into the system. She understood. Like an infant creature suckling at her hand, the spirit gave willingly to her will. She lifted a hand, fingers curled, and plucked the one that felt right, incanting the ‘awaken’ command that appeared in her mind, then reopened her eyes as the dormant displays powered up. Gasps rippled through the chamber. Melitan ignored them.

Adoration had become remarkably old astonishingly fast.

The suite’s long wall was panelled with monitors. They cycled through a sequence of live-feeds from vid-captors situated throughout Zero Tier. While breathless adepts took their seats, Melitan walked to the shorter row of monitors at the end of the suite. The wall was just a few metres long and slightly curved, as if tracing part of a larger circle. Which it was. The monitors displayed views of the quarantine chamber through which Exogenitor Louard Oelur had brought her into the inner tier. She had to actively remind herself that that had been today. It felt like something that belonged in another life. The clean room looked much as she remembered it, albeit now viewed from various elevated angles through vid-captors buried in the ceiling ductwork. Three full maniples of skitarii legionaries had crowded into it since, surrounding a single, massive, kataphron weapons construct.

Melitan frowned at the display wall. She had spent her life in rooms like this one, but there was little comfort in its familiarity. Indeed, there was barely even familiarity, as if the memories were someone else’s, simply stored inside her head.

‘If the skitarii choose to launch a counter-attack, then those priests should hold for a minute at least,’ said Seleston, appearing behind her. ‘I wouldn’t have minded a skitarius or two.’

‘It’s their interconnectedness,’ Melitan answered, without having to think about it. ‘When one goes, they all go.’

‘I see.’

Melitan turned back to the screens.

‘There’s no cover in there,’ Seleston observed.

‘Is that good or bad?’

The secutor shrugged. ‘If we can move something large inside, there’ll be nowhere for them to hide.’

‘I don’t think we have anything that big.’

‘What about her?’

They both turned to look at Fall, the Harlequin sitting cross-legged on a table, watching the bustling adepts through a mask made of her own splayed fingers.

‘Airlock protocols would trap her inside for thirty-three seconds before the outer doors unlock. I think thirty skitarii and a kataphron might be too much even for her.’

The secutor nodded agreement.

It was impossible to pass in or out of the inner ring without holding the sec-suite adjoining quarantine. Of everyone, only Melitan commanded the authority to do that. She knew that, but the idea of remaining here while the others broke out did not exactly fill her with joy. For all the Harlequin’s alien strangeness, there was a part of her that would have done anything to keep Fall at her side. She had proven herself devastatingly effective at close quarters. Melitan sighed. But if the Harlequin had proven anything at all it was that she was the only one who stood a chance of breaking out of the Noctis Labyrinth. Melitan simply had to trust the eldar to care enough to get the warning out without her.

Seleston jabbed her lightly in the ribs with an elbow. ‘We’ll think of something.’

Melitan hoped she would not disappoint. For her own sake as much as the secutor’s. Anything else to suggest, Nicco? It seemed that she and the Palpus meme-proxy had gone beyond first name familiarity and into indiscreet nervous contact. The meme-proxy said nothing. Whatever it had done to save her from Oelur’s guardians she was beginning to think it had resulted in its destruction. Not a pleasant thought, given where it had been implanted, but it was not one she had time to dwell on.

She was on her own.

‘Sir.’

A flustered adept in the robes of a xenoiconographer turned from one of the monitor feeds. There had been some uncertainty amongst the magi about how to address her. Magos did not seem sufficiently respectful. Lady had been used a few times, but never again. Sir had ultimately won out.

The adept called her attention to one of the screens above her.

The jumpy black-and-white feed showed an analytica suite, overturned chairs, bullet-riddled tables, the vid-captor focused on an elevator door. The same elevator by which Melitan Yolanis, under the guise of Magos Biologis Bethania Vale, had accessed Zero Tier not so many days before.

Melitan gasped.

A Space Marine stood in it.

His armour was black, the scratchy greyscale showed the substantive battle damage and trim in varying depths of grey. He was unhelmed, head bald and mutilated. His right eye was a bionic, surrounded by spring-cables and focusing gears. The most striking feature, however, was his jaw. Nose, mouth and chin, all had been cut away, the entire suite of features replaced by what appeared to be a metal funnel. Melitan knew that face well.

She was the one who had saved that Space Marine’s life, after all.

‘Kardan Stronos,’ she whispered.

Heavy weapons fire from off-capture battered the Iron Hand as two more warriors, this time unarmoured, emerged from behind his armour to engage. The weapons’ fire abruptly stopped. For a moment, Stronos stood alone in the field, wearied, yet heroically defiant, like the statue of a long-dead martyr. He looked up at the vid-captor, the feed churning with electromagnetic distortion thrown out by his bionic eye. Melitan raised a hand as if to touch him, allowing herself, just for a second, to be the little girl who had looked up at the age-blackened frescos of Fabris Callivant and dreamt of serving the Adeptus Astartes.

‘I had no idea you had followed me to Mars,’ she murmured to herself.

Was this Palpus’ doing? Had he engineered this in case the worst should happen and Zero Tier required the sort of retributive action that only an Iron Hand could provide?

‘Sir?’

Seleston was looking at her with wide eyes. Commanding the base’s quiescent technology by word and gesture was one thing. Personal familiarity with the Emperor’s angels was, it seemed, altogether another.

Melitan drew her plasma pistol. ‘To the quarantine chamber. We have a new plan.’

II

A reverberative grunt rang from Stronos’ mouth as transuranic rounds hammered his plastron, hyperdense armour-piercing heads drilling for meat they would not find. Pistons shuddering, servos grinding, Stronos advanced. The skitarii arqebusiers of Zero Tier were wilier than the crazed menials of Scholam NL-7, and never allowed him to get close. They performed staged withdrawals, set up enfilades and frequently sent ranger maniples to pop up behind them. One of Thecian or Barras would fall back to run them off, the close quarters favouring the size and power of the Space Marines, and Stronos would grind forward, like a locomotive with its front plough on the tracks.

Thecian and Barras took potshots over Stronos’ pauldrons, using his body as a shield. They carried autopistols picked from the corpses of the menials slaughtered by the elevator entrance. The weapons were ridiculous in their hands, their fingers barely fitting inside the trigger guards to fire. The skitarii weaponry was larger, more powerful, and certainly abundant, but without the proper equipment Thecian had deemed it too dangerous.

So autopistols it had to be.

Stronos shuddered towards a fork in the corridor, shells battering his armour from both sides as the retreating legionaries split into two.

‘Which way?’ he asked

‘Right,’ Thecian slurred.

The Exsanguinator had been able to glean a generalised layout of Zero Tier and the probable location of the Dawnbreak cache from one of the infocytes in the access wards. Thecian had an exquisitely potent omophagea organ. A characteristic of his gene-seed, so he said. Dried blood coated his teeth and speckled his face. His eyes were glazed, only barely keeping some rabid frenzy locked away.

Stronos was beginning to understand how that felt.

His body had become a single vermillion glyph. It pulsed angrily, wantonly throwing out warning sigils and pain. His augmented vision spun wildly, unable to stick to a wavelength. One of the selection rings must have taken a hit, broken off the locking teeth. His flesh eye locked on to the ever-distant block of skitarii legionaries with bloody intent.

‘You can’t keep on like this,’ Barras roared. The Knight of Dorn’s unpowered plastron showed scars of its own, but it was still recognisably a piece from a Corvus Pattern Mk VI powered suit, unlike the irradiated moonscape of Stronos’ battleplate. ‘If we had somehow brought the Rhino in it would have surrendered by now.’

‘On Medusa, we make things to last.’

A door burst open. A maniple of vanguard skitarii armed with spasming close assault weaponry crowded the prayer chamber inside. Stronos blocked them with his body, crushing the alpha to the ground and buckling the door frame. They hacked at his armour. Something bitter and repressed wriggled against the blocks in his mind. Ignoring the damage, he ripped the door off its hinges and hurled it. Something in his mind came crashing down, that feeling of anger intensifying as it sensed freedom. The door bounced and scraped down the corridor, careening over the front, crouching, rank of skitarii and ploughing into the standing legionaries behind.

Hearts pounded. Stim-glands spiked. Red bled into his split vision. From some deep reserve, he drew power enough to build speed.

The rage was a flood now. The barriers were broken. It spilled over them, crashed through, tore out what was left of his defences in a spiteful wave.

With a roar, he thundered into the stunned legionaries.

He ripped, punched and gored, tore limbs from bodies, pulverised exoskeletons and crushed bodies to soupy pulp. He killed, killed, killed until there was no longer an interval between. Hydraulic fluids stained his boots as he drove through the shattered maniple. The corridor became an antechamber, a heavy airlock door leading to a ribbed isolation corridor, but Stronos barely differentiated. He elbowed, headbutted, maimed and trampled. He killed until he could no longer see for the blood in his eye, and then he killed some more. He heard raised voices behind him. Barras. But Stronos could no longer reason an answer.

He felt a change in the atmosphere, enough to pierce the red fog and make him look. He wiped his eye on an iron thumb.

He had passed through the plastek corridor and entered a circular chamber. The walls were baffled, concealed pipework running beneath the surface. The floor plates were riveted. The ceiling was high, too high to reach, scanning lasers blinking from the tangle of ducts and cabling. His armour’s auspex glitched and seized, scattering the chamber with low-level hazard markers in response to several masked augur sources. Priority threat tags filled the gaps. Thirty-one heavily armed skitarii swung carbines that had previously been trained on the airlock door opposite, onto him. A single kataphron breacher pivoted on its caterpillars. Its arc claw spasmed with power, deepening the creases in the battle-servitor’s haunted rictus of a face.

There was a shout, Thecian this time, quickly dulled by heavy steel as the airlock began to roll shut. And Stronos lunged for the kataphron with a yell.

III

Melitan heard the hiss of normalising air pressures as the hermetic seals broke and the airlock door ground slowly open. Her ears popped. Kitha Seleston hopped from foot to foot, nervous, eager to get moving, clad in carapace half-armour reminiscent of a stripped-down skitarius exoskeleton, a pair of gamma pistols clutched to her padded chest. The rank and file of priests and tech menials were strung out behind her, the corridor bristling with taser goads and electrostaves, ripe with human terror.

‘Can you make it open any faster?’ asked Seleston.

‘No one can alter the tempo.’ Fall drew her hands apart from her face to throw Melitan a cockeyed smile. ‘Not even Pride.’

The giant cog-toothed door continued to roll, the sound of gunfire and machinic screams whistling in over the rushing of air.

Abandoning the sec-suite was suddenly not the idea it had seemed at the time.

The airlock had moved far enough to allow a body to squeeze through. Seleston needed no second urging, breathing out and wriggling through sideways, spraying the clean room with violet-soaked ray-bursts from her leading pistol. The Harlequin followed daintily behind, spinning into the fray like a carnival assassin. Once the parting had widened enough to allow the mustered magi to cross two by two, the will of the crowd forced Melitan through at the crest of a wave.

Stumbling out of the rush and looking for a wall to stand beside, she swept her pistol into her eye line, sighting down it as she jerked it right, left.

Numb, she lowered it again.

The skitarii were already dead. They lay strewn over the quarantine chamber, bodies ripped apart, helmets staved in. That mechanical squeal was louder now, coming from the kataphron breacher that occupied the centre of the chamber. It stood taller than two men, but was better described as a servitor-operated light tank. The organic crew-component was encased in heavy armour, machined into a tracked chassis that was itself layered with thick skirts of plate. Stronos, or some wrathful incarnation of the Iron Hand she had known, stood on the sloped front, grappling with the servitor’s weapon grafts. His iron prosthetic had forced its torsion cannon up, his gun-chewed gauntlet holding its arc claw down. Stronos emitted a motorised growl from his funnelled mouth. The kataphron was starting to give off an oily smoke from its joints.

Seleston, Fall and the rest watched, hesitant to intervene.

Without thinking about it, Melitan aimed her pistol at the broad power rack mounted on the kataphron’s back and fired.

A split-second connection linked her weapon’s flared nozzle to the battle-servitor, then plasma ignited and a blue sun the size of her clenched fist blew a hole in the kataphron’s back. Power fled almost immediately. The servitor’s limbs fell slack; Stronos grunted in surprise as he found himself wrestling with a pair of lifeless weapon-arms. The Iron Hand battled the dead limbs for a second longer, the servitor continuing to make aggressive eye-movements and sounds even though it no longer had the strength to wield its heavy combat mounts. He let go of the torsion cannon, then the arc claw, backing slowly off, looking around the chamber wild eyed. He was breathing hard, face greased with sweat.

Threshold-level kill-frenzy.

The diagnosis entered her brain before she thought to look for it. She had no idea where the information came from, but she was starting to get used to that now. Another symptom of the meme-proxy’s burn-out, most likely.

Whatever the source, she saw it now – the flaw in the Iron Hands’ condition.

At first glance, the solution to such failures of inhibition was further reduction in the organic component and concomitant increase in the mechanical. But there was a recursive imbalance in the formula that was painfully obvious to her now, an error that carried over with every reiteration of the equation. The answer, ironically, was for even more drastic reductions in the organic. At zero the errors would cancel out, and the Iron Hands’ emotional flaws would be eliminated.

Remembering the fate of Tubriik Ares, memory-failure, madness and ultimately, death, she felt suddenly guilty and pushed the thoughts away.

Her pistol was still too hot to holster but, not wanting to approach Stronos in his current mind armed, she palmed the weapon into the hand of a gawping magos.

For one petrifying moment the Iron Hand tensed like a chronogladiator, overloaded with stimms and driven into a ring. Servos ground together. Fibre-bundles and exposed cords of augmusculature bunched, ready to explode, crush the half-machine child that stood there before him. But he didn’t. Recognition came, dulling the insanity in his eye. His optic whirred to focus, slipped, whirred, an endless cycle of fail and repeat.

‘Enginseer Yolanis?’ he breathed.

‘Is he… talking to you, sir?’ said Seleston, looking over her shoulder.

Melitan ignored her. Her saviour status would likely withstand the revelation of her true identity now. And if not… Well now she had Kardan Stronos as back up.

‘You have changed,’ said Stronos.

Melitan laughed, surprised, but then she regarded the Iron Hand and her eyes narrowed. Something seethed under the warrior’s metal skin, a passenger in his systems, the ghost of something that did not quite belong. ‘So have you, I think.’

The Iron Hand’s expression darkened. A trickle of blood oozed from a poorly closed wound around his scalp.

Melitan reached up as if to touch the hollow tube that had replaced his nose and mouth, but held her hand halfway. Mirroring her, Stronos ran his finger along its lower curve.

‘I never had the opportunity to thank you before you were reassigned,’ he said.

‘How many times did you do something similar for me?’

‘None.’

Melitan chuckled.

‘Sir?’ said Selaston.

‘Enginseer Yolanis saved my life. She shared her rebreather with me when my helmet was damaged, risked her own life. If not for her intervention, then Kristos would have killed me on Thennos.’

The secutor regarded Melitan with open mouth.

‘About my reassignment,’ said Melitan. There was something she had been wanting to confess to Stronos for some time, and who knew when they would have another chance? ‘About Ares’ death–’

‘The Ancient is gone. His death is irrelevant now. I would know what are you doing on Mars?’

Melitan shrugged. ‘I was going to ask the same question.’

‘I have come for the Dawnbreak Technology.’

‘To remove it?’

‘To destroy it.’

Melitan studied the Iron Hand for a moment. ‘Good. That’s good.’

‘You judge me now?’ Stronos grunted, straightening in a growl of tortured gears. Like a great tree about to fall. ‘You have changed more than I realised.’ His gaze wandered, taking in the ragtag militia that Melitan had assembled. The Harlequin, Fall, returned his regard with an angling of the chin and a bow. He studied the alien for a long time before coming to the unspoken conclusion that they all had an overriding common enemy for the time being.

Melitan found herself assessing him in turn, and approving. He was abandoning dogma in favour of pragmatism, becoming a consensus-seeker, a calculus-former. An Iron Father. He had come a long way from the insular idealist that she had left on Medusa. A smile that did not yet fully fit her proportions spread uncomfortably across her face.

‘You still have not told me what you are doing here,’ said Stronos

‘The same reason as you, I think. After my duties with Ares came to an end, the Voice of Mars sent me here.’

It was Stronos’ turn to think, to nod approvingly. ‘Good.’

She raised an eyebrow and smiled. ‘Do you judge me, Kardan?’

‘Is it Kardan to you now?’

A thump on the outer airlock door interrupted them.

Two more Space Marines, one unarmoured, the other partially, peered through the armourglass between the solid metal spokes. Melitan recognised them both from the live feed on the elevator. The part-armoured warrior, a slab-muscled giant with a murderer’s eyes and a zealot’s frown, glared at Fall who replied with a theatrical bow. Stronos held up a hand to bid the other warriors calm.

‘Can you open the door to my brothers?’ he asked.

‘Do you trust them?’ said Melitan. The warrior in the airlock looked in no way appeased by Stronos’ entreaty, or the Harlequin’s antics.

‘They are my brothers,’ said Stronos.

Melitan thought about it, then shook her head. ‘We would need to return to the sec-suite. There are still a hundred or more skitarii and thousands of indentured workers locked in with us in here. If we’re going to do this then we should do it, go straight for the containment chamber. I can show you the way.’

‘No.’

‘No?’

‘No.’

Melitan glanced at Seleston, who looked sharply away. There was no mistaking who was in charge now. Given that she had spent her entire life at the lower end of the chain, the sudden reversal made her angrier than she would have expected.

‘You bring an alien. They are my brothers,’ Stronos said again. ‘They are coming with me.’

IV

Stronos was exhausted beyond imagination, numb, his power pack spitting power into his systems like attacks of cramp. He felt sick, spiritually and mentally, his last fight with the skitarii drawing on something more than mere electrical power. Every so often, Thecian glanced his way, but Stronos ignored him. He was not ready to discuss what had happened.

There had been some fighting at the doors to what Yolanis declared to be the observation derrick, but it was almost all over by the time Stronos dragged himself into pistol range. Yolanis’ priests milled amongst the dead, congratulating each other on another great triumph, though to Stronos’ eye it had been Barras and the enginseer’s unsettling ally, Fall, that had done most of the killing. The pair eyed each other suspiciously from opposite sides of the battlefield. For now, they were allies, but Stronos was unsure what was to be done about the alien once the mission was over. It was a decision that went beyond the sort he was accustomed to making as a sergeant.

Yolanis went to examine the doors. They were sealed tight, the various panels and status lights dark. The panelling had been pried from the walls, cavity spaces spilling coils of springy cabling that ran into a series of portable generators. Their noisy thrumming was quite audible now the fighting was done, the smell of combusted promethium filling the corridor. Stronos watched the enginseer as she fussed over the assembly.

She had changed. Physically, she was much as she had been when they had last parted on the rad-deserts of Thennos. Her skin was dark, the marks of malnourishment and childhood illness like an old fingerprint on her skin. Her bald head spasmed with the same electoos, her teeth were the same greyish plastek. She had acquired a few augmetics since he had seen her last, her robes were finer, but there was something new to her that went beyond the sigils she wore and the metal in her dermis. The hunch she had always walked under was gone. She stood straight now, her stride was long and confident, all trace of timidity purged from her manner and her speech. There was a set to her face now that was commanding, almost cruel.

Hard to believe it had been less than a year.

‘Stand clear,’ said Yolanis, and set her hands to the door.

There was a judder that made Stronos’ heart lurch, and the great door began to rise. He signed the cog across his chest as Melitan turned towards him, a half-smile on her face as though something had just been settled between them.

There were no more enemies on the other side.

A few bodies littered the walkway, which, by the cleanliness and the variety of the kills, he judged to be the Harlequin’s handiwork. Yolanis was either lucky or blessed. Stronos was not sure he would have tolerated the alien’s assistance had he been in her place. But then Yolanis was weak and he was strong. Perhaps therein lay the advantage of weakness. He trod on corpses, too weary to avoid them, the gantry creaking under his weight and that of his brothers, reminding them of the abyss they walked over. He looked down, struggling to sound out the depth before realising his auspexes were down.

‘Only one way left now,’ said Yolanis, moving to take the lead.

Stronos did not stop her. She had more than earned her place.

Lumen sources blinkered on where she walked, winked out as she passed, a guttering arch of illumination that followed the former enginseer like a halo. Screaming wretches beat at the glass walls of their hanging cells, eyes closed against the sudden brightness, screaming even louder as Yolanis walked by and plunged them back into darkness. Each was a fleeting glimpse into madness and the horrors kept coming.

The barriers across the end of the walkway, when at last it arrived, were massive.

Five metres broad, fifteen high, runes of noospheric dampening and spiritual containment hammered into the rolled adamantium. The symbols glowed faintly with the light residual of their own power. The chamber they were built in was a black sphere hung over an abyss, held in place by the derrick itself and by numerous struts and guys that in the dark were all but invisible but for Stronos’ augmented sight, unstable though it currently was.

‘Can it be opened?’ he said.

Melitan nodded once. The sheer stature of the barrier had subdued her, or perhaps it was the knowledge of what lay beyond.

‘I will go with you,’ said Thecian.

‘And I,’ said Barras, proudly, his loud voice echoing in the dark.

‘That would be unwise,’ said Yolanis.

‘Why?’ Barras glowered down at her.

The former enginseer turned to Stronos. There was a sadness hidden behind the cool mask she seemed to wear now, and he understood. Behind those doors lay a corruption that had almost overwhelmed NL-Primus.

It was possible that someone was going to have to kill him when he returned.

He glanced at each of his brothers in turn, wondering which of them would do the deed, and knowing that either would do it gladly if asked. The thought warmed him.

‘I will go alone,’ he said. This was something he had to do. He could defer it to no other. Not Thecian, not Barras, not Yolanis or her pet Harlequin. It had to be him. Prideful, he knew, but pride had ever been the first flaw of the Iron Hands, and the last. Perhaps it was time to stop fighting it and embrace it. ‘What can I expect to find in there?’

Yolanis opened her mouth to answer, then let the air out in a breath. She looked to Fall, who cocked her head, noncommittal. ‘I have no idea.’

CHAPTER EIGHTEEN

‘This, I do not think, can be explained.’

– Logi-Legatus Nicco Palpus

I

They took Lydriik’s Rhino. Ruination was an awesome machine, but too slow, and incapable of travelling that kind of distance unnoticed. And Lydriik was still hoping to locate the technology and report to Harsid before Nicco Palpus even realised he was no longer in Meduson.

The Rhino had bumped off the Felgarrthi Mountains several hours ago, heading steadily north-east, and onto a featureless expanse of duricrust known as the Ralgus Verge. Lydriik did not know who Ralgus was, if the feature was even named for a person at all. The servitor driver dully repeated Chaplaincy cants as Verrox fed it data. The Iron Father was continuing to work on obtaining coordinates from the file descriptors, occasionally tossing insoluble scraps of data gristle to the brooding hulk sat on the metal bench opposite. The giant never spoke, but he seemed to have a mind like a cogitator; whatever tangled complexity the Iron Father threw his way, it emerged as clean binaric a few seconds later.

‘They are for more than just guarding the Iron Council,’ said Verrox, noticing Lydriik’s interest.

‘Do you ever wonder why they never speak?’ said Lydriik, suppressing a shudder.

‘Perhaps they have nothing to say.’

For a moment Lydriik was sure that the Helfather turned to look at him, lenses dark as a window at night, soul empty, but he convinced himself that it was just the Rhino going over the rough terrain. He turned to look out of the tiny viewing portal behind his bench.

There was not much to see: rocky black hardpan and the occasional swirl of dust. The Verge was seldom frequented. There were no exploitable resources here, and little by way of salvage. It was the abode of the hunted, the destitute and the desperate. An Iron Hands armoured carrier had little to fear from the banditry of the clanless. The land on its eastern borders on the other hand…

‘We have something,’ said Verrox, holding his data-slate to his face in a great sledgehammer of a fist.

Lydriik watched at the portal.

He already had a sense of foreboding about where they were going.

>>> INFORMATIONAL >> THE MEDUSAN SHADOWLANDS

The Shadowlands, sometimes known as the Land of Shadow, is a place of dark myth and fearful legend, wholly in keeping with Medusan superstition and the Iron Hands’ treatment of the deep phobias they all share and cannot acknowledge. Few enter. Those that do tend to be Endurist pilgrims or Mechanicus Explorator missions, for even amongst the Iron Council the fear of the Shadowlands pervades. It is a place of forgotten temples and metallic relics, a land where the dead are believed to linger and where rogue intelligences lie dormant, where living machines of malign and inhuman intellect await the extinction of man and the rise of their kith. It is, of course, also the land where the primarch Ferrus Manus fought his most famous battle, against the silver wyrm Asirnoth. It pains me to iterate the obvious, but the theorem [CYCLICALLY REVIVED BY EACH NEW GENERATION OF SAVANTS] that the origin myths of the Canticle of Travels provide convergent evidence to the existence of machine sentiences and creatures of living metal is pure fantasy.

The region is vast and intrinsically unmappable, and so long as orbital surveyance remains an impossibility, then logic must remain subservient to legend.

Use this to your advantage.

II

They disembarked close to the Iron Father’s coordinates. Lydriik went first, bolt pistol pointed into the gusting storm, helmet auspex frazzled by static. His force axe burned in his other hand like a brazier in a storm gale, held low at his side, the wedge-shaped blade haloed by white light and buzzing grit. The vague shape of a pyramid loomed out of the storm before them, half buried in black sand. A faintly greenish emanation leached into the wind.

‘The legends are true,’ Lydriik breathed.

‘Nothing on auspex,’ Verrox voxed back, helmet to helmet. He was still on the Rhino’s troop ramp, a few metres behind, and looking up at the pyramid. ‘This place is deserted.’

The Iron Father’s Tactical Dreadnought systems were more powerful than Lydriik’s Mk VIII, but some instinct made Lydriik throw up a hand for Verrox to wait.

‘Come no closer, Iron Hand.’

The voice was snatched up by the wind and flung at Lydriik in pieces, making it impossible to identify its source by sound. Lydriik saw it instead: twenty-three candle-bright souls, about fifty metres ahead, half as many again dug into foxholes in the dunes above. The voice had come from the first group.

The storm gave up a dozen human shapes, and for a second Lydriik was reminded of the living dead that roamed the Shadowlands, but he assured himself that the undead would likely not possess mortal souls. They ran towards him and Verrox, fanning out. The majority appeared to be women, hard of body, clad in synthskin bodygloves, faces goggled and bulging with rebreather gear. Two by two they dropped to one knee in the sand and took aim. Each one carried a hellgun, hooked up via high-capacity cables to the hotshot pack on their backs. Lydriik noted as well the assortment of swords and knives sheathed about their bodies. Their spirits were hard, bright and bitterly righteous.

He had felt its like before, when he had served alongside Captain Harsid.

‘My name is Lydriik, Epistolary of the Borrgos Clan.’ He lowered his pistol, and held his force axe low where it was. ‘I was once a companion to one of your sisters – Laana Valorrn.’ He felt the softening of their attitudes, although none of the cultists physically altered their posture.

‘Then why is she not here?’ the voice called back.

‘The last I heard she was heading to a Knight world called Fabris Callivant. It is far from Medusa.’

‘Then why are you not there?’

‘I am an Iron Hand.’ Lydriik moved his axe up to lighten the deep nightshade-blue of his armour and the silver hand on his pauldron. ‘It was time for me to return home.’

‘You know these people?’ Verrox growled in his ear, his breath reeking of motor oil.

‘Death Cult, sworn to the spirit of the primarch,’ Lydriik whispered back. ‘I have fought alongside one of their number before.’

The Iron Father squinted up to the uncertain smudge of the pyramid ahead, a strange hunger reshaping his face. ‘The Enduring Legion. There have always been rumours…’

There was a crunch of sand and another bodygloved woman walked through the waiting assassins. She stopped well back from Lydriik, her hellgun and bayonet pointed into the ground.

‘If you were with our sister, if you knew of us and what she fought for, then why have you come?’

‘Laana understood that the xenotech had the power to break the Iron Hands of our reliance on flesh, to sever our link to the primarch.’ Several of the cultists muttered and cursed. Lydriik waited for them before continuing. ‘She never told me that a component of it was already here.’

‘She has hunted alongside the alien for many years. This part was given into our keeping only recently, but it is our privilege to guard it, to preserve the integrity of the primarch.’

‘Strength eternal,’ some of the women muttered.

Lydriik frowned towards them, their guns unwavering.

Why would Kristos and Yeldrian both turn to the same group to assist them in tracking down the Dawnbreak Technology? There was more going on here than Lydriik was seeing.

Verrox laid a mammoth gauntlet on Lydriik’s shoulder plate, then moved to stand in front of him. Twelve hellguns clattered up. ‘I am Verrox, of the Iron Council. And my passage will not be denied.’

One of the cultists suddenly shifted her aim up to cover something large that had just rattled the Rhino’s embarkation ramp. Lydriik did not need to see the look on the masked woman’s face to realise that the Helfather had just exited the Rhino.

He made a show of holstering his pistol.

‘We are not here to fight.’

‘We were told that there were Iron Hands that might come looking for it.’ The woman glared suspiciously at Verrox. ‘Even from amongst the Iron Council.’ She turned thoughtfully to Lydriik. ‘You say you knew Laana.’

‘As well as she would let me,’ said Lydriik, a rueful smile that the woman would not be able to see spreading across his face at the memory. ‘She… unnerved me, just a little.’

The assassin gave a snort, which her sisters took as a signal to lower their weapons. ‘You really did know her.’ She waved to her sisters, some kind of gestural language with a root in Adeptus Astartes battle-sign. It was dissimilar enough to confound Lydriik’s attempts to eavesdrop. ‘My name is Sara. Sara Valorrn.’

III

Their boots scuffed on the dark metal flags, Lydriik’s like a chisel on a diorite sculpture, Verrox’s heavy and careless, more like a sledgehammer, the noise echoing out through the long hall. Tall, glass-sided cabinets dotted the space, lit from within, like columns of light reaching down to an ocean trench. They held what looked like relics, torn scraps of parchment, a scorched piece of armour, a bit of glove. Pedestals of finely carved basalt stood in watery pools of ultraviolet. Somewhere a fountain gurgled. It had the air of a library. Or a shrine. Lydriik turned on the spot, looking, a sense of wonderment he could not quite explain rising inside him. Verrox looked like a dog commanded to sit, and Lydriik knew that the Iron Father would be aching to be loose amongst these relics.

Sara threw off a string of gestures, her sisters dropping back to take up unobtrusive positions about the hall. Lydriik noted that they kept their hellguns charged and primed. Then the assassin pulled off her mask and goggles, scratching ruefully at the synthskin rash over her shaved head.

The resemblance to Laana was striking. Sharp lines, hard angles, ash-pale, eyes that could somehow look upon a Space Marine in his glory and express disillusionment, as if she had been raised on legends and the truth of them fell short.

‘Wait here,’ she said. ‘The Superior will decide if you are to be trusted or not.’

Lydriik did not ask what the outcome would be if it was decided that they could not. He glanced to Verrox, who nodded, understanding, gesturing in turn to the Helfather who stood beside him, patient as an alien monolith in the sand.

Sara’s footsteps squeaked and echoed as they receded down the hall.

Lydriik was tempted to suggest simply leaving, now, while the assassin was absent. His objective had been to locate the Dawnbreak Technology, not to secure it or to retrieve it, and he was satisfied that that mission had been fulfilled. The logical course was to return to the Telesterax with all haste, expropriate the use of an astropath and direct a message to Fabris Callivant for Yeldrian’s witch to intercept.

But Verrox spoke first.

‘An Endurist fane,’ he breathed. ‘There were legends, but no one ever ventures into the Shadowlands. It is said they founded their temple here shortly after the Dropsite Massacre. Before the first ships and messages could have reached them, some say, forewarned by a visitation of the primarch’s own undying spirit.’ He looked slowly over the interred relics. ‘They gather his possessions and await his resurrection.’

‘I know the myth,’ said Lydriik.

The Endurist belief also had a minority following within the echelons of the Chapter, and Lydriik was well aware that Verrox was its most prominent adherent. The Chaplaincy generally turned a blind eye, seeing factionalism in all its forms as firmly in keeping with the competitive doctrine of the primarch’s recorded values. Provided the truth of Ferrus’ fallibility and death remained sacrosanct, almost anything else remained open to challenge.

Verrox moved towards the nearest cabinet. It held a single fragment of armour, the back part of a rerebrace, shaped to fit over a warrior’s tricep. It was mangled by battle damage, aged beyond recognition, but even at a glimpse it was plainly too large to have ever fitted the arm of a standard Legiones Astartes warrior. It was not significantly smaller than the slabbed cuisse that plated the Iron Father’s thighs.

‘Is this his?’ Verrox wondered aloud. His gauntlet thudded gently on the glass, his face pressing alongside it. No mist clouded the glass. The Iron Father’s breath was cold.

Lydriik shrugged and said nothing. He knew that it was wiser simply to wait, as the assassin had asked, but he could not deny his own kernel of curiosity.

He came to a plinth.

The angular lump of basalt was a little too low for him, the round lip engraved with beasts and dragons and men in armour bearing longrifles and hunting lances. On it rested an open tome, an ivory reading wand set on the polished black stone beside it. Curiosity at last winning him over, Lydriik leaned in for a closer inspection.

The text was ancient Medusan. The chirography was brief and efficient, simple illuminations decorating the marginalia. There were only a handful of shades that could be ground from Medusa’s dark rocks, and Lydriik recognised the blacks and greys from his studies of the ironglazier’s craft. All were native. The pages were brittle and greyed with age.

He looked around, but the watching cultists seemed indifferent to his interest. Verrox had already wandered to another cabinet.

Sliding his gauntlet fingers under the binding, Lydriik carefully closed the book for a look at its cover.

The binding was some kind of dark reptilian leather, weather proofed with a thin layer of ironglass that had preserved the material even as the pages inside had mottled and dried. An image had been etched into the underside of the glass, the colour and texture of the underlying leather exploited by the glass with a skill at which Lydriik, no stranger to the art, could only marvel. It depicted a warrior in old Medusan plate steel. Such armours, forged from native materials of awesome scarcity, were the preserve of warlords and kings, and had been quickly discarded to history in favour of the armaplas and plasteel that came with the planet’s rediscovery by Mars. Even without much to reference a sense of scale the figure was a giant. His musculature was fantastic, his shoulders broad, his eyes hard, pressed with pigment to look like bolts of silver. His immense arms were wrapped around the coils of a gigantic wyrm, its head snarling behind the hero’s shoulder.

Lydriik stilled as he realised who the figures were.

Ferrus Manus. Asirnoth.

The book was the Canticle of Travels.

His fingers tingled as they ran over the ironglass sheath. The oldest known Canticle text was dated to the early centuries of M33, compiled from oral stories by a visiting magos anthropologicae who never put his name to the compendium. Lydriik had given one such priceless tome to Kardan Stronos as a gift, something by which to remember their long discussions of philosophy when he had departed to become Prime Librarian to Clan Borrgos. This book plainly predated M33. The runescript, the materials, the pigmentation, all were native to pre-Imperial Medusa.

And it was clearly not oral.

With a creak of stiffened parchment, he opened the book to a random page and picked up the ivory reading wand.

…and taking advantage of the beast’s distraction, Ferrus Manus did approach the Chimerae with spear in hand, and…

Lydriik blinked, as if the book might have been switched without his noticing. He read on for a few more lines. He set the wand down.

Taking hold of the plinth, he drew a deep breath.

That was not how the story of the Chimerae went, the way every Iron Hand had been compelled to read and memorise it for the last seven thousand years.

He barely noticed the echoing squeak, until Sara had returned the length of the hall. Another figure followed serenely after her, draped in red and gold. The Superior. Lydriik felt his heart sink.

Kristos and Yeldrian had not propositioned the same cult after all. Kristos had had nothing to do with it.

It was Nicco Palpus.

‘You,’ Lydriik breathed. ‘Did Yeldrian know?’

Nicco Palpus looked amused by the question. ‘I doubt it. For a species so adept at manipulation, they possess a curious blind spot for it when the tables are turned.’ He spread his hands. ‘But then, can something similar not be said of us all?’

‘Who is Yeldrian?’ said Verrox.

‘It does not matter now,’ said Lydriik. ‘What is going on here, Palpus?’

‘I was going to ask you something similar, but the answers are all superfluous now.’ The logi-legatus’ attention glanced at Lydriik, passing to the opened Canticle on the pedestal beside him. ‘You are dogged, Epistolary, I will grant you that much. The Dawnbreak Technology, I could have explained. My interest in keeping it here, I could have explained. I would have, if I had to. But this? No.’ The logi-legatus frowned, and to Lydriik he appeared genuinely saddened. ‘This I do not think can be explained.’

‘I will know what you are talking about,’ Verrox grumbled at Lydriik.

Lydriik pointed at the book. His arm was shaking. ‘That the Mechanicus has been rewriting Medusan doctrine for at least seven thousand years. I have fought alongside the Brazen Claws, and the Red Talons. I have argued with them over the proper interpretation of the stories.’ He thrust his quivering finger at Nicco Palpus and shouted. ‘And they were right! Throne have mercy on us all. They were right all along. They are the true inheritors of the primarch. Not us.’

Palpus shrugged. ‘And?’

‘And?’ The question was so ludicrous that Lydriik had to laugh. ‘You bastardised us.’ He waved his hand angrily over the open book. ‘There is more of Mars here than Ferrus Manus.’

‘Is this true?’ Verrox growled.

‘What if it is?’ said Palpus. ‘Ferrus proved to be flawed. The stories we wrote for you were simply reflections of that newer truth.’ He sighed, gazing at the tome. ‘Destroying the original would have been deeply unorthodox, however. I could not quite bring myself to do it.’

‘Do not think yourself so important in this, Palpus,’ said Lydriik. ‘Your counterfeit is thousands of years old.’

‘Call it a figure of speech.’

There was a snarl as Verrox plodded forwards, the Helfather his enormous shadow. ‘Why?’

‘You ask why? You are no simpleton, Iron Father. To make you better. Mars wants the same thing you want, it always has.’ The logi-legatus took a neat step back, placing Sara Valorrn between himself and the furious Iron Father. ‘You know, of course, that I cannot let you leave.’

The assassins around the hall stepped out of concealment, hellguns whining as they came up to their chests.

Verrox bared his grinding teeth. ‘You want to do this, Palpus? I have been waiting five hundred years for an excuse.’

The Voice of Mars nodded as though they were old friends, skirting around the need to say goodbye. ‘We have all been alive too long.’

‘You.’ Verrox motioned with his gauntlet to signal the Helfather behind him. ‘Kill him.’

The Helfather’s chainfist buzzed to life. The stacked barrels of his assault cannon rattled as they loaded, the combi-flamer hissing as the pilot light ignited.

And touched the pallid skin at the top of Verrox’s neck.

Palpus tutted. ‘You Iron Hands are all the same, though some of you always manage to surpass your genetic predilection for self-importance. Kristos for instance. You are a lot like him, you know. You never wanted to see where the real power lay.’ He spread his palms in a gesture of apology. ‘Well now you see. Cherish your enlightenment.’ He nodded to the Helfather. ‘Kill him.’

>>> HISTORICAL >> THE BATTLE FOR FABRIS CALLIVANT

Information pertaining to the fate of Fabris Callivant is sketchy and it is entirely plausible that by the time this exload arrives you will have a more complete understanding than I.

Fabricator-Locum Exar Sevastian was reported to have made it off-world in a Taghmata gunship although his ultimate fate remains unknown. The orbital aegis was beginning to disintegrate at this time, with the Alloyed and the Shield of the God-Emperor both being confirmed destroyed shortly before the report was logged.

The fate of Iron Captain Draevark is unknown.

The fate of Princeps Fabris is unknown, his last reported coordinates placing him in Fort Callivant’s lower quadrants, firmly in the vicinity of the orks’ ground assault.

The fate of Mirkal Alfaran is unknown.

For all our sakes, pray that you never cross paths with a Hospitaller after Fabris Callivant.

The Knight world is far from Medusa and any world of import. Let the affairs that were conducted there be recorded as belonging wholly to Kristos’ folly…

CHAPTER NINETEEN

‘We all have our weaknesses.’

– Autarch Yeldrian

I

Rauth wasn’t sure what offended him most. There’s too much going on at once. He was still coming to terms with the sensation of traversing the warp without technically being ‘at warp.’ There was no nagging itch under the skin, no whispers in his ear, no moments of heart-stopping dread, fuelled by the certainty he was being followed, only to turn, pistol drawn and find the passage behind him empty.

‘My people seldom risk voyaging through the warp as do the mon-keigh,’ Yeldrian had explained.

‘Human’ suits him well enough when he’s talking about me, personally.

‘Mon-keigh’ is for everyone else.

I should be flattered.

‘You are the last person I would expect to suffer a fear of the warp,’ Rauth had replied, indicating the pack on the eldar’s back.

Yeldrian had smiled at that, the fleeting condescension that came so naturally to his race. ‘Small distances, a heartbeat of cosmic time. She Who Thirsts dwells in the warp, but She is not the warp. I would have to be reckless or unlucky.’ His mood turned in an instant, a blackness rolling in. ‘But it happens.’

The autarch would say no more, and Rauth was content for the eldar’s daemons to remain the eldar’s business.

The experience of hurtling through the endless branches of the eldar webway in a merchant schooner devoid of Geller field or warp drive might have been one he could contend with, had it been taken in isolation.

Were the hold itself not geared to the sole purpose of driving me mad.

It was a kind of motion sickness, all the more intolerable for being unrelated to any physical evidence of actual motion. The looming stacks of boxcrates did not so much as creak. Indeed, given the incalculable speeds at which the Lady Grey must have been moving, the sense of being becalmed in the warp was disconcerting in itself. Rather, the view from the corner of his eyes never quite tallied with what he saw directly ahead of him. He had already lost track of the number of times he had startled at the approach of some half-glimpsed nightmare, only to see the phantom vanish the moment his sidearm was turned on it.

Screams and bolter fire faded into the labyrinth of the hold, echoing through the creases and folds of his brain.

Again, Yeldrian had sought to explain.

‘Holofields and hallucinogen barriers. I have protected you,’ he had added, pre-empting the inevitable question. ‘But those Iron Hands who made it aboard before we lost Kristos in the webway will be beset by every nightmare of their psyche.’ An unpleasant thought. No one has nightmares like mine. ‘Killing them will be a mercy.’

Even that disturbs me. A little.

Not killing them, of course. That was mana for his soul, the least he could give back after the years he had endured.

It’s the prize that troubles me.

After all he had seen and heard, he had been expecting something hideous: garish alien plasteks studded with discoloured gemstones and dripping with fell energies, peering into his soul, probing for weakness. Being surrounded instead by standard template Departmento Munitorum boxcrates was both anticlimactic and more than a little unnerving.

Rauth wasn’t sure what offended him most.

Perhaps it’s not even just one thing. I have ample cause for offence.

‘Where is my brother?’ he asked, every so often.

‘Almost there,’ was all the reply the eldar would give.

After ten to fifteen minutes of brisk walking, they found him.

Four staggeringly high walls of bronzed boxcrates stamped with warding runes and aquilae defined a chamber of sorts at the middle of the hold. A set of large crystals dappled the sides, like luminescent alga at the bottom of a well. A matrix of semi-organic cabling, an amalgam of alien plastek and artificial bone, ribboned the decking, and hooked the crystals into an organic, pulsing series. Rauth’s eyes adjusted quickly to the changing light levels. The boxcrates were filmed by a web-like material, phantasmal creatures crawling over them like spiders. He shivered. The worst thing is, I don’t even know if they’re real or not.

‘Is this more like what you were expecting?’

Rauth nodded.

‘This was the vessel of a wealthy merchant. Its hold is more secure than its bridge or its engines.’ The eldar pointed to the glowing crystals. ‘These stones generate the holo-defences throughout the ship.’

Wordlessly Rauth looked around, assessing the place for defensibility and vulnerabilities.

Then he turned towards his brother.

Khrysaar was laid out on a levitating slab of bone-plastek, stripped to his loincloth, his scarred, muscular form orbited by blinking, chirping gemstones about the size of a coin. They appeared to be communicating with an array of smooth-bodied, elegantly inhuman gem diodes set up to one side. There were no drip lines or knives that Rauth could see. Just a softly chiming geode sitting on the unconscious Scout’s forehead. Rauth started towards the grav-pallet, odd feelings of protectiveness and affection bubbling up inside. Yeldrian reined him back with a light touch to the shoulder.

Rauth almost turned and struck him.

He stared at his clenched fist as if someone had pressed a short-fuse grenade into it. What am I thinking? If he knew one thing for a fact, it was that a fight between him and the autarch would have only one outcome.

With an outstanding effort of will, he lowered his fists.

‘He is in no danger,’ said Yeldrian, calmly, as if he could smother Rauth’s temper with his words as he would a flame with a blanket. ‘You have both been guests here many times.’

Guests. It sounds so agreeable. ‘How many times?’

‘There will be gaps in your memory. This is why.’ The eldar indicated the grav-pallet. ‘You were correct. Before. I did not recruit you and your brother for your abilities. Laana was perfectly capable of locating the technology alone.’ He smiled thinly, as if missing the human assassin. ‘I believe she resented your assistance, but she trusted me. You and your brother had been touched by the artefact on Thennos. If I had let you return then the corruption might already have decimated your planet. Lydriik arranged for your secondment, interceded with an Iron Father named Verrox on my behalf.’

I don’t know this Verrox. Presumably I saw him on the Iron Moon. Rauth reached up to touch the single iron vertebra of Clan Dorrvok and winced at the memory of its installation. Oddly enough, I remember little else of that day.

‘Bringing you with me also gave me the opportunity to monitor you, and it gave me access to your mind.’

I remember none of this. ‘What’s so special about my mind?’

‘I believe that you saw the artefact on Thennos, or at least came close. Kristos’ psyker blocked your memories. Lydriik tells me that it is a well-worn technique amongst your own, for eradicating unwelcome thoughts and behaviours.’ The eldar sighed, lowering a hand to sit on Khrysaar’s bicep. ‘It may repress the contagion, if it exists, but it cannot destroy it.’

A shadowy eldar in darker armour that Rauth had failed to notice amongst the cherubic lights and the horror of his unconscious brother approached the grav-pallet. Rauth stared, dumb. My brothers are not the only ones being confronted by their nightmares. Something about the figure’s physique told him that it was a female. Something less prosaic screamed ‘witch’. She stood taller even than Yeldrian, taller than Rauth. Her helm was high and fluted, her visor a featureless black plate, long neck studded with aquamarines. Her form-fitting body armour was a muted yellow, similar to the autarch’s albeit of a bleaker shade, replete with osseous runes and partially shrouded by a pale flax cloak.

‘Imladrielle Darkshroud,’ said Yeldrian, and the alien woman dipped her head. ‘Any word from Lydriik, or from Elrusiad?’

A shake of the head.

Rauth shuddered.

Doesn’t she speak?

A pair of slender armoured warriors flanked her. They were tall and willowy, and yet their stillness was absolute. They remind me of Medusan stick insects, waiting years and years for a pheromone-whiff of prey. They stood a head higher than Darkshroud, and broader too for all their apparent delicacy. Their plastek helmets were swept back and perfectly smooth, no ports for eyes or mouth. Their only feature was a rune that, despite its alienness, reminded Rauth of the old Medusan symbol for infinity. Each stood in a posture of eternal, near-statuesque readiness, a long-barrelled heavy cannon of alien design in their large hands.

‘Darkshroud has been working to remove the blocks that Kristos placed over your memories,’ said Yeldrian.

‘What?’ Rauth dragged his gaze away from the looming ghost warriors. ‘Why?’

‘Either you were affected or you were not. Denying the event will not change your fate. Ayoashar’Azyr will out, in the end.’

Rauth felt his anger drain from him to pool around his toes. He glanced towards Khrysaar. ‘And is he…?’

‘He is untainted.’

Rauth breathed out in relief, but something in the eldar’s manner made his heart lurch.

‘I am sorry.’ Somehow, Yeldrian already had his laser pistol in his hand and pointed at Rauth’s chin. ‘On some level, I suspect you have known for some time.’

Rauth’s eyes locked with Yeldrian’s.

Sweat from his fingers ran around the grip of his bolt pistol, still down by his side. He was quick, his reactions pushed to the limits of human physiology. But only to the limits. I’m not that quick. Emotions began to spill out of him. Impossible to tell where one ended and another began. Fear for himself. Love for his brother. Relief that Khrysaar would live. Rage that he would not. Hatred. Hate I know. It was the mantle that bubbled under his skin. Hatred of Yeldrian. Hatred of Kristos. Hatred of his brother for living. Hatred of himself for not. Myself most of all. Turning into the monster that Tartrak and Dumaar had wished of me, even as I swore I was stronger than that, vowing I would fight back as soon as I had the strength to win. Well this is it. Fight and die, or surrender and die. I know what I should do.

The inevitable can’t be fought.

With a howl of blind rage, Rauth drew his pistol.

Yeldrian moved like light, his laspistol spitting out beams and searing the muscle from Rauth’s shoulder before the bolt pistol was out of its mag-holster.

The flurry had been meant for Rauth’s head.

He may not have been as quick as an eldar autarch, but he was close, and managed to turn his expendable, organic shoulder into the fire, soaking up the punishment even as he pulled his pistol free and fired back.

A combination of the turn and the pain caused him to drag his bolter-burst wide. Shells whistled across the autarch’s body and punched through the boxcrate wall, the detonations rupturing the cheap alloy and throwing out packing plastek as though it had started to snow.

Yeldrian threw a startled glance into the shower and held up his hands, letting his pistol dangle from the trigger guard.

‘No one wishes to die, but do not forget your brothers still aboard this ship. If the emitter crystals were to be damaged, then they will come. They will recover for Kristos what we took from them.’

For a second, Rauth thought he would fire. Why don’t I fire? But when it came to it, he supposed he despised his brothers more than he hated the eldar who wished to kill him. He slid his pistol back into its mag-holster. ‘You should have shot me while Mohr had me in the apothecarium.’

‘He would not have allowed it, and I had no wish to kill him too. I still need him. And besides.’ He gestured to the grav-bed. Khrysaar was still under. Darkshroud and her guardians hadn’t moved. That’s confidence. ‘You deserved a proper farewell.’

Rauth sighed. ‘Weak.’

Yeldrian brought his pistol back towards Rauth’s face. ‘We all have our weaknesses.’

Lasered light burst from the weapon’s jewelled nozzle.

Time seemed to stall, the universe zeroing in on the moment as if Rauth’s life were in some way precious to it, that its passage were an event to be witnessed and marked. The sense of his imminent mortality closed over him like an inflated bladder, being squeezed, squeezed, until it burst.

Time accelerated as an Iron Hands Terminator materialised into the line of fire, laser energy splashing off his backplate like water off a rock. Rauth gaped. Ribs of plasteel bulked out his already massive plastron. Thick metal plates with giant rivets protected extraneous bionics. A vast ammunition hopper was machined to his back. He dominated his space like a supermassive black hole dominated its galaxy, and Rauth could think of nothing else but to watch as the Terminator raised a pair of assault cannons and opened fire on the holo-crystal array.

Rauth’s mind exploded.

He dropped as though shot in the head, his brain doing everything in its powers to convince him that the deck plates were running from under his hands like sand. The walls rose, fell, wobbled like towers of gelatine. Bat-winged horrors became chitin-plated monstrosities, then died garish deaths as Traitor Space Marines. Twin assault cannons charged his nerves with thunder. He tried to reach his pistol, but couldn’t seem to find his hands. Why isn’t it affecting the Terminator?

He knew why. All the scouts had heard the rumours.

Helfather.

‘He followed us,’ Yeldrian screamed. ‘The arrogance of him.’ The autarch slid his hell mask back over his head. ‘Destroy it. Before it is too late.’

The ghost warriors had already stepped in front of Darkshroud, distortion waves rippling from their cannons and blasting chunks of the Helfather into temporary dimensions. It didn’t even slow his rate of fire. Laser blasts mottled the ancient Terminator plate, to negligible impact. Yeldrian cursed in his own tongue, powered up his blade, and charged.

The eldar had learned from his battle with Draevark. He didn’t pierce or stab, looking to terminate the Helfather with a clinical thrust to a critical organ, instead hacking as much damage into the Terminator as possible before the silent hulk could respond.

The Helfather shouldered the eldar into a crate, and Yeldrian crumpled like a parchment figurine.

Face set, Rauth drew his pistol and pushed himself up against the wall of crates.

He aimed for the back of the Helfather’s head, just as another forced compression ran through his stomach. His ears popped. He held his fire, knowing what was coming and suspecting that he was about to start having to pick his targets.

Six additional figures unravelled out of the empyrean, smaller than the Helfather, but giants still in their own right. Iron Hands. The cogwheel emblem of Clan Raukaan had been etched in silver on their shoulder plates, pulsing under the hellish strobe of the Helfather’s assault cannons. He saw the warrior that commanded them.

Omnissiah. Emperor.

Please, no.

Rauth felt his body go numb, as if he had been touched by a Medusan stone elemental and flash-petrified. He stared with mineralised horror, the bolt pistol forgotten in his hand. Dumaar. The Apothecary looked him over and appeared to perform a visual dissection, telescoptics wittering and whirring.

‘Navicular and cuneiform bones destroyed. First degree laser burn to the right deltoid. Cutaneous perforations indicative of gunshot wounds, incompletely treated. Loyalties… compromised.’ Rauth felt his mouth hanging open. Emotions he had no idea how to contend with had paralysed the muscles in his face. ‘Unsalvageable.’

He snapped out of his haze, dragging his aim from the Helfather to deliver a four-shot squeeze into Dumaar’s plastron. The first bolt incinerated on contact with some kind of energy field, the next three blasting messy chunks out of the Apothecary’s armour.

Unfazed, Dumaar’s pistol swung up as though operated by remote.

The air exploded with bolt-rounds. Rauth flung himself out of the way, mass-reactive explosions chasing him into the one piece of cover he could find.

Khrysaar’s grav-bed.

The Apothecary’s bolt spray obliterated Darkshroud’s medicae equipment, producing a string of muffled detonations that rippled through the unit like shots fired into an oily liquid.

Drawing a breath, Rauth ejected his pistol’s spent magazine and slammed in another, shuffling to the far side of the alien machine and stealing a glance around.

The Helfather and the two eldar ghost warriors were tearing chunks out of each other’s armour, seemingly content to dish out firepower until one or all were destroyed. The witch, Darkshroud, made an intricate sequence of phrases and gestures, the plastek armour of the warrior melting before her words, extruding auto-rounds and spitting them to the deck plates as the damage was undone. Then her head exploded. Rauth swore as alien gore showered him and the eldar witch slumped over the grav-pallet beside him.

Muttering to himself in a hash of mutually exclusive lingua-forms, Dumaar reloaded.

The Apothecary circumvented the crush that was closing around Yeldrian like a fist, walking slowly towards Rauth.

Rauth furiously loosed another round. It burned up on the Apothecary’s energy field, the disparate metals that clad his skull colouring under the flames. I won’t go back to lie on Dumaar’s table. I won’t. He emptied the entire magazine into the Apothecary, pushing past the four-shot limiter with repeated pulls on the trigger. Dumaar just kept walking. With a howl, Rauth ejected the spent magazine and hurled it. It bounced off the Apothecary’s cheek.

A second reality implosion disgorged a fresh Iron Hands Terminator.

This one I know.

Countless ironglass engravings depicted his likeness throughout the Broken Hand, the Clan Borrgos monastery, and they had met once, when Arven Rauth had submitted to the final tortures and become Clan Dorrvok.

Kristos.

The Iron Father’s helmet lenses flashed in sequence, a towering beacon of rugged ceramite and darkened plasteel. He and Yeldrian saw one another at the same time.

The autarch leapt clear of the floundering assault clave with a battle cry and folded into the air, re-emerging in a blizzard of colour to rake his blade down the Iron Father’s back. The eldar darted away, spun, folded into the immaterium and returned from a fresh angle. Kristos’ arm dislocated and rejointed, turning his power axe back to beat the autarch’s blade aside. Yeldrian angled his sword, let the cog-toothed axe-blade run off its length, then delivered a shriek through his mask that knocked the Clan Raukaan assault clave to the deck and made Rauth, several metres further back, clutch his ears in pain. Kristos re-ordered his limbs and slammed a bolt through the autarch’s chest, only to find the eldar already tearing from the ether behind him. Sparks hung in the air as they fought, the Universal Laws locally suspended, the explosive grace of the eldar meeting the Iron Father’s indomitable power.

Perhaps we can win this yet.

Rauth dragged his attention away as Dumaar coolly shoved Darkshroud’s corpse off the grav-pallet, optics affixing on the geode affixed to Khrysaar’s forehead.

‘Theorise, hypnotic inducer.’ The Apothecary emitted a code blurt as his lenses scanned over Khrysaar’s body. ‘Lacerations. Bruising. Physical damage minimal. Mental damage possible. Irrelevant. Reclamation by Clan Borrgos is justified.’ There was a wittering exchange as he and a number of the discrete systems of his armour conferred. ‘Reclamation approved. Proceeding.’

Rauth’s breath came out hot.

No.

He dragged his knife from its boot sheath and plunged it into the Apothecary’s arm while his attention was on Khrysaar.

The long blade severed the soft flex-metal between vambrace and rerebrace. Gases whistled from the elbow joint, swiftly cutting off as the flows were redirected. Rauth dragged his knife out and backpedalled, keeping his distance, sending another scything knife stroke towards the hip, though Dumaar brushed it aside with his gauntlet. Pain thumped down Rauth’s arm and he bit down a moan, circling around the Apothecary, criss-crossing his knife before him.

‘We aren’t going back.’

‘It is a common misconception that anger increases a body’s unit strength. It does not.’

Dumaar’s hand clamped over Rauth’s fist, breaking the blade in half and crushing the bionics of his hand up to the radial and ulnal stress rods. With a cry of pain, Rauth allowed himself to be driven to his knees. The Apothecary stared down at him, a chirurgeon assessing a gangrenous limb. Dumaar was the oldest Iron Hand in the Chapter, and the strongest. He was legendary. Rauth could only scream as the ligaments and flexrods melding the augmetic limb to his organic shoulder wrenched slowly apart and colour spots burst across his eyes.

‘Variant of the Mark twenty-five-delta forelimb augment. Plasteel-nickel alloy with aluminium gearing. Apothecary Geraint’s favoured specification. Lightweight. As is Clan Dorrvok’s preference.’ He tightened his grip, the metallic forearm squealing under the Apothecary’s crushing grip. Rauth’s vision swam as stimulants flooded his blood-brain barrier in a bid to keep him from passing out. ‘Flawed. Highly flawed.’

Rauth tried to pull away, but Dumaar held him by his own useless bionic. The fight was leaking out of him, droplets of red splashing onto the deck. Even Space Marine clotting factors and pain suppressors could only push a body so far.

‘Flesh is weak,’ he muttered.

‘Your statement is non-revelatory,’ said Dumaar.

Rauth bared bloody teeth as Dumaar raised his bolt pistol. Take it then. Take the Dawnbreak Technology and be damned. He laughed suddenly as he stared along the Apothecary’s pistol muzzle. ‘I’m laughing at you,’ Rauth spat. ‘And you’ll never understand why.’

‘I don’t care to,’ replied Dumaar, shooting him in the face.

II

Autarch Yeldrian saw Darkshroud fall, Rauth following the spiritseer swiftly into Ynnead’s embrace. In the heartbeat he had, he mourned them both. Imladrielle had walked with him along the Warrior Path when the Alaitoc were young and still in mourning. And Rauth, for all that he had been condemned to die, had not deserved his death.

There was a crash as one of Imladrielle’s wraithguard hit the floor, its legs carved from under it by the ghost Terminator’s cannon hose.

‘You outdo even yourself,’ Yeldrian snarled, launching into a blistering combination of blade routines and random warp jumps that Kristos parried with methodical efficiency. ‘Losing yourself in the webway simply to claim that which will damn you.’ Yeldrian found an additional burst of speed, flickering in and out of the warp with such reckless abandon that at times he could see four or five reflections of himself duelling with Kristos’ rotating limbs.

‘Navigating the webway is not impossible,’ said Kristos, speaking evenly as his torso blurred with speed. ‘Only supremely improbable. Improbability is simply inevitability viewed over too short a time frame.’

A sudden shift in fighting styles bulldozed Yeldrian’s intricate sequence of guards and drove him onto his back foot. He skipped back, danced, blade flicking out to create an opening, but Kristos yielded nothing. The Iron Father’s systems had assessed him and found his measure. This fight was already over. Yeldrian scowled.

He refused to see his life end like this, fighting to protect the mon-keigh from themselves.

‘The Sapphire King will have your soul, Kristos,’ he panted, giving ground until his back was to the stacked crates. His hands felt numb, as if they reached halfway across the veil to be grasped by Ynnead’s own two hands. ‘We may have built the artefact, but it is his now. You cannot hope to use it without first allowing him to use you.’

‘You think me ignorant.’

‘You know?’

Kristos’ axe broke through Yeldrian’s enfeebled guard, striking the powerblade from his hand, and then the Iron Father kicked him in the chest, crushing him between the Iron Hand’s enhanced strength and the wall of crates behind him. Bones cracked. Carapace tore. Yeldrian slithered to the ground. Kristos towered over him. What he saw when he looked upon Yeldrian’s Banshee masque, no creature of sanity could guess. ‘Daemons are a product of mortal fears and mortal emotions. They are a mirror manifestation of flawed souls. How better to protect oneself than to shed one’s soul? We will become iron to our core, impervious to weakness from within as we are from without. The Dawnbreak Technology will help me do this.’

Yeldrian shook his head, too weak to stand. ‘I thought you naive, but I did you a discourtesy. You are a madman.’

Kristos levelled his storm bolter. Yeldrian stared down the barrels.

He considered flight. One leap and he could be gone from this place. He could seek out Ymir, rouse Harsid, whoever else still lived, and continue the fight another day. But he had been profligate already, reckless, and he would offer only so much to this cause.

He drew the line at his soul.

‘Eldanesh too sought parity with the gods,’ he said, looking up, lowering his hands to the ground. ‘It ended poorly for him.’

III

Jalenghaal looked down on the ostentatiously armoured corpse of the eldar general, its body ripped apart and strewn over the neighbouring surfaces. The movement caused him considerable pain. A mass-reactive through the spine tended to produce that effect. Karrth had suffered more greatly, if briefly. The surviving members of his clave, Burr, Hugon and Thorrn stood behind him like zombies. The eldar’s psyk-out weapons had left them beaten, bludgeoned, baffled, but they still stood strong. Jalenghaal felt proud. The hallucinogens must have overloaded his cognitive inhibitors.

‘I cannot raise any of the warriors deployed to the aft sections,’ said Kristos, without turning. The Iron Father’s storm bolter was still trained upon the alien mess, as if some logic error denied that the eldar could be dead.

‘It is dead,’ said Jalenghaal.

Kristos lowered his weapon slowly and turned. ‘The Brazen Claw and the Death Spectre are confirmed dead. The Wolf remains unaccounted for.’

‘Clave Jalenghaal is ready to obey,’ said Jalenghaal.

‘Holo-defences remain in effect over several areas of the ship. Hunting down a single Wolf would be an inefficient use of resources and time.’

Jalenghaal had not been invited to contribute and so maintained his silence.

‘Commence transfer of the Lady Grey’s cargo to the Omnipotence, then cast her into the warp. The Wolf will soon discover what happens when one defies the calculus.’

‘Compliance,’ said Jalenghaal.

This part of the cargo hold looked like a battleground, after the scavenger servitors had picked over the scraps and left the residue to the bacterial fauna.

The boxcrate stacks that formed the walls had been torn apart by heavy fire, packing materials – wire wool and reconditioned plastek – and auto-casings lay over the bodies like fungal growths. Some of the bodies were still moving, the Iron Hands of Assault Clave Tarik attempting various permutations of ‘standing’ despite the lack of three or more limbs. Their robotic persistence, the sheer logical incontinence of it, was unnerving in the extreme.

Again, Jalenghaal chose to put it down to the eldar’s psyk-out effects.

A Helfather stood motionless in the far corner.

The ancient looked like a plastek explosive that had failed to detonate. The warrior stared at the wall, lenses dark, but the echosounding ping of Jalenghaal’s auspex assured him that the giant was alive and aware. Stronos had been possessed of the irrational fear that to draw a Helfather’s gaze was to draw bad luck, but Jalenghaal believed it then. He looked away, moving with an awesome lack of fine motor control towards the grav-pallet that still hovered over the carnage.

A Scout lay on it. He had come through miraculously unscathed, discounting the mess of older injuries and chirurgical scars that were unremarkable on any Iron Hand of a given age. Half the youth’s face had been swallowed by a conch of metal, a nacreous optic sunk into the middle of it. His left hand was metal. He was slowly coming around, murmuring what sounded like a name.

‘Arven… Rauth… Arven.’

‘Is that your name?’ said Jalenghaal.

‘Brother? Is that you?’

From the floor, Dumaar looked up. The Apothecary was wrist-deep in gore, rooting through the neck gristle of the second Scout. It seemed unlikely that the Scout’s progenoids would have been fully matured, but Iron Hands Scouts tended to be older than their counterparts in other Chapters. It was impossible to know for certain until they were out. The Apothecary regarded him in silence for several seconds, optics lensing in and out, as if considering whether to divulge something of import, only to decide not to and return his attention to his corpse.

‘Rauth…’ the Scout muttered, sinking back into heavy unconsciousness.

Appearing by Jalenghaal’s side, Kristos placed a gauntlet onto the head of the pallet. ‘I have lost many warriors today. Almost as many as my predecessor at Skarvus, and more will be lost yet before Qarismi can map a course back to our galaxy. Transfer the neophyte to the Omnipotence along with the contents of the hold. See him to Niholos for cerebro-reconditioning.’

‘Compliance,’ said Jalenghaal.

‘Rauth will be joining Clan Raukaan.’

CHAPTER TWENTY

‘Who are you?’

– Kardan Stronos

I

The doors slammed behind Stronos, entombing him in darkness. It pressed on him like a weight, as though centuries without breathing had caused it to curdle and become thick. His armour’s struggling olfactors reported trace aromatics of rust, dead insects and advanced cadaverisation. Despite lacking a genuine sense of smell, or taste, his face wrinkled in response to his armour’s senses. He crunched his cheek muscle into his eye socket, switching the optic to heat vision. A diorama of yellows and greens smeared into view, running like wet paint as the broken selection rings slowly slipped down the spectral range.

The containment chamber was as spherical on the inside as it had appeared from the outside, but smaller, the thick ferrocrete walls layered with adamantium and lead. A loosely panelled walkway extended into the dark’s gaping mouth.

Stronos slid his boot forwards. The rig groaned, echoing, eliciting a small cry from the iron corbels bolted to the ferrocrete. Nothing here had seen a priest or received a blessing in years, possibly in over a century. He emptied his lungs slowly. It was not a fall that worried him. He estimated the chamber to have an inner radius of about five point four metres, a drop that he could endure even in his current damaged state. It was the climb back up. There were no imperfections in the ferrocrete, no handholds, or rungs machined into the wall.

If he fell down, he would be staying down.

With abiding caution, he moved his back foot forwards. The walkway trembled, but it looked as though it would hold. Looking up from his feet he crunched his optic a second time, forcing his vision back to the far-red.

An ichthyic bulge of wire flax and smooth carapace podules rose out of the nightmare of colours like a leviathan of the Oblitor tarn. It was a runny turquoise to his eyes, dribbling zones of cooler shades that resembled gemstones. Stronos recognised the heat signature and the material properties. Wraithbone. Stronos’ one hundred and fifty years of service had been given almost exclusively to countering tau expansion in the Western Veil, but he knew the work of the eldar when he saw it. Wraithbone was a psychically grown plastek analogue, harder than plasteel; it did not rust with exposure or warp with age. The Rhino-sized assemblage before him looked now as it must have looked when it was made, yet age cloaked it like the mantle of a neutron star. Before the Emperor had sent His Great Crusade to reclaim the stars for mankind and to found the Imperium, this machine had performed to alien whims. Ten thousand years. An inconceivable span of time.

It looked dead, but it was not dead. It was choosing to lie dormant. Waiting.

He knew that he was not alone in this chamber.

He lifted Barras’ knife towards a clot in the smear of heat-bleed half a metre to his right. Tension racked into his augmuscles like metal rods. He forced his hand to lower the knife, letting his breath out with a sigh. It was only a servitor. With his free hand he manually clicked his optic rings back to the far-red and held them in place.

There were four servitors. They stood in a line before the Dawnbreak engine, effectively barring his approach, heads sunk to their chests. They looked mummified, their dried skin and hollowed bones held together by the bars and braces of the heavy lift augments they still bore. These must have been the units that had brought the machine here after Dawnbreak, sealed in, left to rot alongside the alien machine.

There was a gasp of congealed air, a click of fossilised joints, and the servitor closest to him lifted its head.

Stronos drew back, knife raised, steady in his grip.

Again that sense, that certainty, that he was not alone.

‘Who are you?’ he asked.

The servitor made no move to close the distance; it simply rolled its head until its gaping eye sockets found his.

The silver edge bit deep into the breastplate of his brother’s armour, and the primarch of the Iron Hands cried out, falling to his knees once again as the blade’s flaring energies parted his dark armour like a fingernail through cold grease. Hot blood sprayed from the wound and Fireblade slid from Ferrus’ hand as he gasped in fierce agony.

Stronos stumbled, fumbling his knife as though it had become suddenly heavy. He stared at it, expecting to see his grip soaked in his Father’s blood. Air slammed in and out of his mechanical lungs. ‘No,’ he mumbled, staring at the knife. ‘No. This is… This is not…’

A second servitor shambled towards him, gripped his face in withered, desiccated hands and forced him to look into its eyes.

The primarch’s grip was locked on to the weapon, and even as he recognised how far he had fallen, he knew that he had come too far to stop, the realisation coupled with the knowledge that everything he had striven for had been a lie.

‘Who are you?’ he croaked.

He fell to one knee. His knife slipped from his grip and clattered to the walkway.

How many times had he revisited that dark day? He still remembered the histories that Chaplain Marrus had drilled into him as a neophyte. He had pored over them since, agonised, they all did, he knew, in their hearts, even if no one ever confessed to it. Their Father was weak. They would not be. Torturing themselves affected nothing.

And yet…

The third servitor lurched forwards. He would not meet its eyes.

It did not matter.

Unnatural warp-forged steel met the iron flesh of a primarch. Its aberrant edge cut through Ferrus’ skin, muscle and bone with a shrieking howl that echoed in realms beyond those knowable to mortals. Blood and the monumental energies bound within the meat and gristle of one of the Emperor’s sons erupted from the wound, and he fell back as the searing powers blinded him, dropping the silver sword at his side.

‘No!’

With a crash, Stronos landed on his back.

All his life he had known anger, known grief, known self-deception and loathing, but for one cosmic instant, he knew it as a being beyond him had once known it. As a god that had spent the life of his brother knew it. A knife pierced his heart. A bar of cold twisted his guts in his belly. His thoughts stopped. This was the end of the universe and the beginning of another. This was where he lived now, this moment, forever, no matter how long he lived or what acts he perpetrated to destroy the memory. This was everything. A halcyon moment of transcendent grief to pierce the veil between dimensions, the beat of a butterfly’s wings that had given birth to a storm.

Curling onto his side Stronos wept, oil and saline dribbling over his cheeks and blubbering from his lips. When had he last wept like this? As a child? An infant? The final servitor loomed over him, offering a shrivelled paw encased in a rusted steel glove. Glimmers of purple fire burned in its sockets. In a rattle of collapsed lungs and liquefied vocal cords it spoke.

‘You know who I am, Kardan Stronos.’

‘You… are the Sapphire King.’

The servitor chuckled, echoed by the quartet of dead mouths.

Stronos drew his hand back along the walkway towards him and concentrated on pushing himself up off the ground. In a squish of dried meat, one of the servitors squatted beside him.

‘Your arm is shaking,’ said the servitor.

‘My systems are exhausted.’

‘Of course. Your systems.’

Again, the servitor offered its hand.

It would be easier to take it than not, use what was given, take the more certain path. He stared at the hand, then took a shuddering breath and pushed himself up onto his knees. He sagged onto his haunches, the stiff armour joints in his legs complaining. A servitor appeared by his shoulder, breathing rasping through its teeth.

‘You would be wise to conserve your strength.’

‘Fight the battles that need to be fought,’ hissed another.

Stronos did not turn, staring back the way he had come as his vision clicked out of wavelength, one nanometre at a time. ‘You were born in the fires of…’ He scrunched his eyes and forced himself to say it. ‘…of Isstvan.’

‘I am the Phoenician’s pain,’ said one.

‘And his exultation,’ voiced another.

‘His grief.’

‘And his joy.’

‘I am his love for his brother.’

The voices swam around Stronos. He pressed his palm into his chest. His hearts were racing. His lungs straining their motors. ‘But this machine. It is eldar. It predates you by a thousand years or more. It has nothing to do with Isstvan, or my Chapter.’

‘Kristos made it about you. It was crafted by the eldar at the apex of their hedonism, an engine to probe their innermost and lift them towards their desires.’ The servitor emitted a crackling sigh, and another took up in its place. ‘Their desire, of course, was pleasure. That is not Kristos’ desire.’

Stronos forced his mind to concentrate, recalling what the Iron Father had said to him on Thennos, shortly before the Iron Father had ripped off his helmet and left him to burn.

‘The Iron Hands falter. The strength of our Father wavers year by year. What the Imperial Guard found on Dawnbreak was a new direction, a path to perfection.’

Was this his meaning, to use the power of the Dawnbreak engine to realise the Iron Hands’ long-held ambition of perfection through metal?

‘Yes,’ the servitors answered as one. They creaked nearer. He felt them behind him. ‘You are weak, Kardan Stronos. Weak and angry. So very afraid.’

Unbidden, memories of the anger he had felt towards Barras for destroying him in the practice ring, Thecian for embarrassing him in front of Magos Phi, his resentment of her. He remembered every black moment, every long voyage spent amongst brothers yet trapped, each of them in their own shell, alone with the bitterness of his nature. He remembered it, for his memory at least was perfect.

Was Kristos’ proposition not couched in logic? Was it not the natural extension of the Iron Creed to take the simple, surer road to their final objective?

He thought then of Draevark, his captain, of Drath and Ares, dead on Thennos. He thought of Kristos. These were ancient warriors, surpassing him by centuries, beings of iron.

Was there one amongst them that was any less embittered or broken than he?

‘I am flawed,’ Kristos had said to him. ‘We are all of us flawed. I seek the same perfection as do we all.’

Stronos shook his head.

‘No.’

There was a hiss of anger as the servitors closed ranks behind him, and in a growl of servos Stronos forced himself to his feet and turned to face them.

‘I will not allow my Chapter to trade its soul.’

‘Why not? It is your weakness. Your ultimate weakness. The Dawnbreak engine can make it all go away.’

Stronos snorted.

‘All of what?’

His memories were vivid and painful, but he found that he was no longer as angry as he remembered. His hearts held on to no bitterness that he could not express. The slow erosion of his humanity and of his Chapter’s soul no longer suffused him with the existential dread it once had. The vessel was broken and what it had held inside was gone. Tears on the walkway, a road of bloodily slain skitarii behind him. Stronos did not think it would ever be refilled again and the thought made him… hopeful.

He was unsure if that feeling was more or less strange than that of wetness on his cheek.

With a shove, he sent the servitor closest to him flying from the walkway. It flailed silently before splattering on the ferrocrete below. The remaining three grabbed at him, steel-gloved claws sliding into grip-holds in his battered plate.

‘Do not think you can defeat me so easily, Kardan Stronos,’ they rasped in unison. ‘I am no creature of flesh. Everywhere a child of Ferrus Manus is tormented by guilt or rage, be they Medusan, Kalavelan, Raikanan, I am there. That is what you would defy.’

The servitors’ bio-augments made their shoulders massive, their biceps bulged with myosin scaffolds and actin ratchets, but the meat of their foundations had rotted long ago. Stronos shook them off, flesh tearing away in clumps, as their prodigious strength clattered piecemeal to the floor. Pushing through them, he advanced on the slumbering machine.

For a moment Stronos could see it, even without his eyes.

And he felt it see him in return.

Blue eyes as hard and ancient as precious stones drilled through the dark between them. A mane of long hair fell from a face that was at once hard and beautiful, shockingly inhuman, yet achingly empathic. His armour was facetted like a jewel, brilliant as a B-type star, draped with white-hot iron chains that spat and fizzled with the creature’s core of fury. Crystalline wings folded partway over its breastplate. Its arms were folded. One hand was metal. Iron.

Stronos blinked it away.

‘The Dawnbreak engine is not me.’ The voice did not come from the servitors now. It came out of the darkness. ‘It is a skin I choose to wear, a vessel I choose to ride. You cannot break me with fists.’

Stronos raised his gauntlets. His vision rained with sapphire afterimages.

‘Then I shall begin with your skin.’

CHAPTER TWENTY-ONE

‘We made you stronger, more resilient, more efficient, less distracted by free will – are these such crimes?’

– Logi-Legatus Nicco Palpus

I

Verrox moved faster than should have been possible for a being of his formidable bulk and age. He knocked the Helfather’s assault cannon aside on his jaw, then bit onto the gun barrel, teeth screaming, chewing out fat sparks as his fist slammed into the Helfather’s girdle plate with a resonant thud. The Helfather did not seem to register the impact, driving his chainfist into Verrox’s thick shoulder armour and beginning to carve. Verrox’s mouth distended, throat rippling with a silent growl; not with pain so much as exhilaration. He had been waiting a century or more to feel that kind of pain. The Iron Father bent backwards. The chainfist dug in. His knees bent, body tensed, the Helfather was halfway through his shoulder, and with a roar Verrox lifted the aged Terminator off the floor. There was a scream as the chainfist came loose, and the Iron Father threw him into one of the glass reliquaries.

The sound of raining glass seemed to shock the watching assassins into life.

Bolts of supercharged las, shifted red, stabbed at Lydriik from the four corners of the hall as he dragged the Canticle of Travels from its plinth and dropped to one knee. Las-fire thumped into the plinth’s thick basalt, his armoured back shielding the priceless tome against the single assassin that still had a clear shot. The powdered smell of baked rock filled his nostrils as he wrapped the book in the hard felt of his equipment pouch.

The Helfather was on his back, lying in a bed of broken glass and unloading his assault cannon into Verrox’s armour. The Vurgaan Iron Father gnashed his teeth and took it, his face thrown into hellish relief by the muzzle flashes as he raised a boot and smashed it down on the downed warrior’s gun-arm. The Helfather’s combi-flamer breathed out, and suddenly both warriors were aflame.

It did not seem to trouble either of them.

Checking that the book was secure, Lydriik forced a fragment of his will into his axe. White light screamed from the heavy blade, rattling the plinth on the flagstones and causing those beneath his boots to reorient as if to get away from the power of his mind. With the strength he had to spare, he let his consciousness roam; it touched the walls, explored every plinth and pedestal and cabinet, the fountain, probed the assassins. There were six of them. He saw them moving, circling to flush him out of cover.

He found Nicco Palpus.

The Voice of Mars hovered a few metres back from where Lydriik had seen him last, apparently torn between seeking refuge and seeing this complication resolved in person. Sara Valorrn stood in front of him, hellgun crossed protectively over her chest. The priest’s metallic eyes shone, reflecting the bonfire that had engulfed Verrox and the Helfather.

With a scowl, ignoring the hell-blasts that had cooked through his backplate in numerous places, Lydriik aimed his pistol at the Voice of Mars and fired. Sara bundled the logi-legatus behind a wide plinth and his burst butchered the stonework.

‘You are better warriors because of us,’ Palpus called out from behind the chewed-up pedestal once the noise had faded. ‘You are better because of us.’

Lydriik hissed as a hell-blast seared his neck, and shifted position to show the shooter his side instead, covering his equipment pouch with his axe hand.

‘You made us slaves of Mars,’ he yelled back.

‘We made you stronger, more resilient, more efficient, less distracted by free will – are these such crimes?’

Lydriik let his bolter answer for him, demolishing a section of the Voice of Mars’ cover. Metal hit the stone at his feet and bounced as he released his magazine and reloaded.

‘That rock is getting smaller, Palpus.’

‘You are a warrior, Epistolary. It was all you were ever meant to be. You could have been content with the greatness we offered, but no, Kristos had to pursue his mad quest to rid himself of flesh, while Verrox there would have you break from Mars entirely. And Stronos?’ Palpus scoffed. ‘Even Stronos does not know what Stronos wants.’

‘If you disagree with Kristos then why not countermand him?’

‘Because he is useful, and because he can be controlled, which is more than I can say for you.’ The soft metal of Palpus’ face appeared from behind the crumbled carving, flushed by the promethium glow and the flash of hell-blasts. ‘Mars is ancient. It is wise. It owns this galaxy and allows, in its wisdom, that the Imperium of Man should exist in it. The Iron Hands are a part of that whether you wish it or not.’ He shook his head sadly, as though forced to reprimand a rebellious serf, and glanced towards the burning Helfather. He was still down, he and Verrox continuing to hammer fists into one another. ‘We possess you.’

A growl rising from his throat, Lydriik rose.

The hell-fire abruptly stopped. Nicco Palpus regarded his assassins quizzically. Lydriik’s eyes pulsed with witchfire. His psychic hood danced with light.

‘And I possess them,’ he said.

Sara’s rifle swung towards the Voice of Mars. She stared at her weapon in shock.

Nicco Palpus only looked disappointed. ‘If only it could be that simple. You cannot kill the–’

The Voice of Mars’ augmented cranium exploded, the forced discharge of a hotshot blast to the back of the head vaporising its cyborganics before they had a chance to spill. The priest was tossed to the ground like a headless doll, skidding a short way before coming to a halt halfway towards Lydriik, steaming.

A furious mewl escaped Sara’s lips, the hellgun shaking in her hands.

A remarkable strength of will.

Pity.

Lydriik severed her body from her brain with a thought and she dropped like a bag of stones. He felt a moment’s regret. He had been genuinely fond of Laana, and would probably have felt the same about her sister too, had circumstances permitted. He walked towards Palpus, holding his will firmly over the trigger fingers of the remaining assassins, and put four more rounds through the Voice of Mars’ back. Detonations ripped through the adept’s body. With the Adeptus Mechanicus one could never be too certain, but if there was a redundant personality store hidden somewhere in the priest’s body then it wasn’t there now.

The crackle of burning flesh and its accompanying charnel stench announced Verrox’s arrival beside him.

‘He always overlooked the flesh,’ he observed.

Lydriik nodded.

‘I thought the Deathwatch had made you soft.’

The Iron Father was breathing heavily and partially aflame, fires guttering inside his mouth each time he opened it to breathe. His right arm hung by a clutch of wires, slowly fraying in the heat. White bone and dark metal plates showed where skin had dribbled away from his face, the motorised gearings and belt systems of his teeth exposed in all their ravenous detail. The Helfather lay amidst broken glass and crushed shell casings and puddles of lit promethium, still now. Dead? Alive? The Helfather was beyond Lydriik’s power to read.

‘It made me recognise my weakness,’ he whispered. ‘That can only make a warrior stronger.’

‘I am rarely glad to be proven wrong. I make an exception today.’ Verrox looked down at Sara. She gasped on the floor like a paralysed fish.

Lydriik laid a hand upon the equipment sack at his belt. ‘This is more important than a human life.’

‘We still need to have a conversation.’

‘We do.’

‘About this Yeldrian, to start with.’

‘I know.’

‘Now seems like a good time,’ Verrox growled.

‘Not now.’ Lydriik looked around, mentally bidding the assassins to lower their weapons and back away. They obeyed. ‘The Dawnbreak Technology will be safe enough here. The cult will see to it.’ He turned back to Verrox, his hand resting protectively over the tome at his hip. ‘First, I need you to summon the Iron Council.’

SUPPLEMENTAL ONE

Talos Epsili awoke with a start, reaching instinctively for the carafe of oiled wine that his servants habitually left out for him on. Perturbed to find it absent from its proper place at his bedside, he extended scapulal dendrites to prop him up in his bed.

His bedchamber was dark, still in its night cycle. The tapestries on the wall, detailed anatomical schema in crimson thread on gold, rippled under the steady nineteen-degree breeze from the atmosphere cyclers. The air smelled of prophylactic counterseptics and of his own nightly soil, usually removed and deodorised well before the conclusion of his sleep algorithms. Scowling, he swung his legs out of bed and checked his bedside chrono. It confirmed his internal count. He had been woken several hours short of his programmed cycle.

Leaning over his knees, servo-mechanisms pushing through the papery flesh of his shoulder blades, he buried his face in his hands. He had an appalling headache, bits of foreign memory and information jumbling about in his head like loose screws.

He staggered up, proprioceptive extensors telescoping to the walls, ceiling and floor to help as he moved to the wash basin. He ran it cold, and splashed water into his face.

The spigot felt different, the water splashing strangely through his hands. He felt different. It could mean only one thing.

Nicco Palpus was dead.

He turned off the water, running his hand back over the metallic discs embedded in his scalp. Something was wrong. He did not yet know what, but the sense of it ate at him, something missing.

The Voice of Mars was more than just a man. It was a chain, unbroken, forged in the heat of the Iron Hands’ transition from a broken Legion to a Chapter with an uncertain identity and no hope in their future. The responsibility was immense, the spans of time involved great, too great for one man, even an adept of Mars. It was decreed that the Voice of Mars could not be permitted to die. A data transposon of mobilisable information had been integrated into the noospheric physicality of that first priest, passing from inheritor to successor, snippets of personality and memory acquired through the quasi-molecular violence of excision and integration to generate a shotgun mosaic of scrapcode insertions and binaric drift that could don the crimson of the Voice of Mars.

As Secondary Voice of Mars, Talos Epsili had known this, had lived for this day.

He knew that something was wrong.

The chain had been broken.

Half the transposon was missing.

Talos stared into the bottom of the draining basin. ‘Where has it gone?’

SUPPLEMENTAL TWO

Stronos emerged from the containment chamber, dragging one leaden boot ahead of the other. He blinked in the light, his fist still ringing from beating on the barrier doors to be let out. Part of him was still to accept the fact that they had been opened.

Yolanis hurried to intercept him, her crimson robes flapping. Thecian and Barras followed close behind, their expressions unreadable, or at least unreadable to Stronos. He noticed the Harlequin, Fall, watching him from just beyond the boundary of Yolanis’ halo, her face masked by her own interlocking fingers.

‘Have you been… weeping?’ asked Thecian. The Exsanguinator sounded oddly impressed, and clapped him on the shoulder.

Stronos’ mouth pipe emitted a wheeze. ‘It will take some explaining.’

‘What happened?’ said Yolanis, stepping back from the three Space Marines so as to look him up and down. ‘What did you see?’

Stronos shook his head wearily. He felt as though he could sleep for a hundred years. ‘I destroyed it. Down to the last gemstone.’

Thecian punched his pauldron, and turned to Barras who grunted an acknowledgment.

Yolanis studied him, frowning.

‘And are you–’

Her mouth hung open, contorting as though the word were somehow stuck in her throat. The left side of her face slackened, the frown falling out. Her right eye twitched. ‘You.’ There was a retinal flash of blue as a circuit overloaded, her spasming tongue forced a trickle of spit over her down-curled lip and the enginseer dropped.

Thecian was quick to catch her, lowering her gently to the ground, while men and women in battle-stained robes rushed towards them with a cry. Barras moved instantly into an aggressive posture, blocking their run on the enginseer and swinging his borrowed autopistol around to aim at the Harlequin. She was the only one who was not moving. Stronos pushed his aim to the ground. The Knight of Dorn glared at him hotly. He ignored it to crouch by Thecian and Yolanis.

The enginseer’s eyelids fluttered, then she moaned, scrunching her face as though in pain.

‘What happened?’ Stronos asked.

Her eyes snapped open, and the intensity behind them took him aback, as though it were a different person looking back.

‘We have to return to Medusa. Now.’

An extract from Imperator: Wrath of the Omnissiah.

‘Almighty Machine-God whose data binds the universe, look upon your humble servant and let the tangents of your intersection be beneficent.’

As ve spoke the ritual lines, Magos Dominus Militaris Xaiozanus Skitara Xilliarkis Exasas dilated the dorsal spiracles of vis intertracular lymphoid to release a cloud of bacteriophagic incense. The vapour billowed as a purple cloud, cleansing the air of biological contaminants that might infect the implant connection points in the few remaining parts of vis flesh.

Vis sense of smell had been replaced by far more complex molecular sensors when vis face had been removed, yet vis sensory system still latched on to the old memories and interpreted the smell as forge exhaust and hot metal. It was an aroma that ve had known since vis first moments in the incense-sterilised hatcheries of Metalica.

Lifting up one of four multi-jointed gripping limbs, Exasas let three drops of blessed lubricant spill from the slender bottle in vis grip. Flexible optical lenses capable of microscopic vision tracked the trio of liquid spheres as they fell past the gantry on which Exasas stood with the other senior tech-priests of Casus Belli. Ve followed their fall for several metres until they hit the gilded crest of the Titan’s head below.

From this vantage point the Imperator continued down into the brightly illuminated main deck of the Legio Metalica landing barge. Arrayed about the feet-citadels of the Casus Belli were lines of white-clad skitarii waiting for the command to board, arranged by squad and platoon, the precision of their ranks pleasing to Exasas.

Ve extended a link through the noosphere that connected to the skitarii alphas far below. At vis invisible command the squad leaders became surrogates for vis physical presence, an extension of vis communication system. Even as ve framed the thoughts, the words were announced by the mouths of the dozen alphas, ringing from across the Titan dock.

‘Tech-guard of the Casus Belli, the perambulations of destiny have again brought us to holy war. Our great Imperator is to be unleashed against the heretek darkness that has befallen Nicomedua. The servants of the Omnissiah have turned from their duties and we shall be the punishment unleashed against them in the name of the Machine-God. The Legio Metalica are blessed to be chosen as the executioners of this sacred task. With our companion-engines we shall see Nicomedua delivered back to the light of diligent service.

‘I stand before you as magos dominus, incarnation of the martial precision of the Cult Metalica. We are one, indivisible, favoured in the working of the Machine-God, for we have been given this sacred duty and in its completion shall move closer to the perfection of the Omnissiah’s design.’

Another noospheric pulse sent the embarkation order into the alphas, who disseminated the command to their squads. In unison, the skitarii offered their weapons in salute and then turned towards the gates of the Imperator’s citadel-like lower legs.

‘I still do not comprehend why you insist upon this ceremony. One might as well expend energy boosting the morale of a circuit breaker.’

Recognising the voice of Zerkei Metalis Gevren, the dominus turned vis centipede-like body to face the moderatus prime. Along with the other moderati, Gevren approached along the docking gantry, passing from the light of the vast chamber into the shadow of the Casus Belli’s akropoliz carapace superstructure.

Unlike the magos and the other tech-priests, the moderatus prime and his companions mostly retained their human anatomy. It was partly in honour of the humanoid form of the Titan, and partly because when they interfaced with the Casus Belli’s mind impulse units it remained more natural for them if they shared the same number of limbs and basic shape. Even the hint of a phantom limb reaction could prove devastating when spiritually connected to a forty-metre-tall war engine.

They wore bulky piloting uniforms rather than robes, though in the same white as the Metalican tech-priests, and each carried their interface helm under their arm.

Gevren himself was a solid figure, broad at the waist and shoulder, with a similarly slab-like face and flat nose. The glitter of implants behind his eyes and a few stud-points in the sides of his neck indicated the presence of the mind impulse unit connections inserted into his flesh.

‘It is not as if your warriors will contribute anything meaningful to this battle,’ added Moderatus Secundus Haili. Her smile was one of patient contempt as the group stopped on the other side of the gantry line, leaving a path to the command module entry ramp. ‘We shall leave them only ruins to guard.’

‘There are some duties beyond even the wrath of the Casus Belli, Zerkei,’ argued Exasas. ‘Tasks that are beneath the dignity of an Imperator Titan, but nonetheless vital to victory. If the ruins need to be guarded, my skitarii will be equal to the challenge.’

‘They are simply martial lubrication, Xaiozanus,’ said Gevren. ‘Human grease for the gears of battle. It is a pity that you waste your intellect with such a dull subject.’

The last moderatus, Rasdia, said nothing, but his expression was one of condescension. The coterie of moderati fell silent at the approach of the princeps senioris. Like them, she did not wear the robes of office, but her single-piece protective suit was more elaborate, decorated with gilded piping and ruby-studded fasteners. Her face was lined with age – and the toll of melding with the psychometric circuits of the Casus Belli. Slender black lines beneath the skin of her neck and throat and in the backs of the hands that held the interface helm betrayed the presence of life-prolonging inserts. She walked with the aid of a cane fashioned from the bone of a Titan-sized tyranid beast they had destroyed on Durasa Four.

‘You are looking at my stick again, magos dominus,’ Princeps Senioris Iealona said. ‘Even with your five independent visual detectors, I can tell when you are looking at my cane.’

‘Your perception is infallible as ever, princeps senioris.’ Exasas constricted vis body segments to shorten verself, bringing vis theoretical eyeline to the same level as the princeps senioris’. ‘It seems an unnecessary peripheral assistance.’

‘And I must remind you again that I cannot risk my harmony with the Casus Belli with further changes to my physiology or chemical balances. So, I must limp.’

She stopped between the two groups, tech-priests of all shapes and sizes to the left, human moderati on her right. As with the Imperator itself, she was the fulcrum upon which the alliance turned, the mechanical and the organic fused within her when she interfaced with the Titan.

‘You wish to test Liberik’s Fourth Theorem during our engagement?’ she said, looking at Exasas.

‘I do,’ the magos replied. Ve caught Gevren shaking his head scornfully. ‘I have proposed a corollary that I wish to enact with my troops, if it is possible.’

‘I will see what can be done, but I think it unlikely there will be any infantry engagement today.’

Despite the life-extension surgeries and cerebral enhancements ve had undergone, the dominus was still capable of disappointment. Ve remained still, containing any display of the emotion before the princeps senioris.

‘I am your honoured servant, princeps senioris. We shall do as the Machine-God moves us.’

‘That we shall,’ said Iealona. She glanced at her moderati and waved her cane towards the zigzagging ramp that led into the open gate in the side of the Imperator’s head. ‘Time to get started. We are due to rendezvous with the rest of our battle group in forty-seven minutes and begin the assault in sixty. Six Warlords, three Reavers, three Warhounds and a pair of Warriors shall be accompanying us. And a whole skitarii support echelon. We shall not keep them waiting.’

They advanced as a group along the gantry. It made Exasas uncomfortable, seeing their individual stride patterns, making no effort to harmonise their movements. Their humanity was meant to be key to their success with the mind impulse unit, but to the magos it seemed like a terrible inefficiency.

Ve spurted an audible packet of binaric at the other tech-priests and together they followed the humans into the Casus Belli.

Each of them in turn briefly approached the small shrine alcove in the docking vestibule, laying a hand or tentacle-like mechadendrite on the twelve-toothed cog symbol rendered in gleaming platinum upon the devotional stand. Exasas placed the tip of a tendril against the symbol and felt a pulse of recognition from the Titan’s dormant spirit.

‘Benevolent Casus Belli, I commend my body to your protection and dedicate my mind to your service.’

An archway led to a corridor that descended into the command module proper, cleansing incense falling curtain-like across the opening. Exasas moved through, inhaling deeply of the strong fragrance, neuroreceptors firing swiftly under the influence of the stimulating agents contained within the mist.

‘Almighty Machine-God whose data binds the universe, look upon your humble servant and let the tangents of your intersection be beneficent.’

The callipers of Ghelsa’s augmetic phalanges clicked as her dark-skinned fingers closed around six meticulously inscribed steel polyhedrons. She lifted them from the polished offering plate and touched them to the breast of her off-white coverall.

Ghelsa kissed her steel-wrapped fist and held the shapes to her brow. Her metal-capped knuckles clinked against the silver twelve-toothed cog set into the flesh of her forehead before she threw her hand down.

Cast from her fingers, the twelve-sided dice clattered into the concave bowl, skittering around the raised lip. Shadows and light played over the spinning, skipping shapes as the silent watchers crowded closer, peering over Ghelsa’s and Adrina’s shoulders as they waited for the dice to come a halt.

The duluz of the downdecks wore a mixture of tabards, half-robes, kilts and coveralls depending on station and expertise. Many showed signs of crude augmentation – either gifted by a patron in the upper echelons of the priesthood or made in one of the basic workshops of the lower spaces. Like Ghelsa’s, their clothes were uniformly off-white, the colours of their hegemaarkhus, the forge world of Metalica. Their formal allegiance colours were augmented with an array of tattoos, piercings, brand marks and other decorations to identify home world, sect membership, personal relationships and other sundry information. Most had not seen the metal-sheathed planet, but were natives of various vassal systems or the detritus of conquest and liberation swept up by the Casus Belli on one of its many campaigns. Ghelsa was one such tributai, sent to serve in the Legio Metalica as part of an ancient pact between the tech-priests and her world of Zakhinta.

The gaming pieces belonged to Ghelsa, who was proud to tell anyone who asked that she had made them herself from bearings that had once been part of the Casus Belli’s starboard hip main rotator. She had salvaged them two years earlier during a rededication to the Machine-God and spent half of that time diligently filing the flat surfaces with a handrasp and autopolish. She had used an acid stylus to etch the twelve sacred symbols, each one of the Perfections of Form as listed in the holy books of Metalica.

A red flare of light played over the settled dodecahedrons – the signal beam from Adrina’s artificial left eye. Ghelsa was quicker to count the revealed symbols than her opponent’s scan-mechanism.

‘Four iambic crucibae,’ she groaned, throwing up her hands in despair.

‘Militus Martia!’ her opponent cried in triumph, reverting to crude Gothic in his excitement.

There was a mix of cheers and moans from the onlookers as various side bets were won and lost.

Adrina held out a pudgy, oil-stained hand, his smile not unkind. Half a tattoo was just visible where his wrist entered the tattered white cuff of his overseer’s robe, depicting the iron skull of the Legio icon. He was epilekhtoz, Metalican-born, hence his higher station.

He beckoned with fingers tipped with broken nails, their golden enamel chipped and scratched.

‘Hand it over, vin Jaint. Everyone saw you swear the wager before the Omnissiah’s oracular.’

She delved a hand into one of her coverall’s many pockets and produced a thin sliver of circuit-covered plastek. Adrina leered as he made to snatch it from her fingers. Ghelsa pulled it out of reach.

‘One downshift only,’ she warned, glancing to the others as witnesses. ‘And if you’re caught, you didn’t get it from me.’

Adrina nodded, his fingers twitching in excitement.

‘Come on, come on, my downshift starts soon.’

Eyes narrowed, Ghelsa handed over the forged datachip. The overseer thrust it into an inner pocket of his robe, hiked his chain of office more comfortably around his neck and gave a smile. He stood, head bent to one side to avoid the condensation-dappled coolant pipe that ran through the small chamber.

‘Always a pleasure, vin Jaint. Luckily for all of us you’re a better spindle-wrangler than you are a player of Omnissekh.’ The crowd parted to let Adrina pass and they filed away, ducking beneath the various cables, pipes and other impediments between them and the small hatch that led back into maintenance duct S-11.

Notasa lingered for a moment after the others had left, his gaze suggestive, which was impressive considering his eyes had been mirror-sheathed, the orbs like pure quicksilver.

‘You can’t win at everything, Ghelsa,’ said the diminutive duct-runner. He leaned back against the bulkhead, arching his neck like a contented feline. ‘But no need to be sad for long.’

‘The lower port manifold array is coming loose,’ Ghelsa said with a grimace of lost opportunity. ‘I really should go and fix it.’

‘Always so dutiful,’ snapped Notasa, his anger fuelled by rejection. He flicked stained blond hair from his face, revealing skin pocked with tiny scars from errant welder sparks. ‘You know they’ll never make you epilekhtoz, no matter how hard you work. You’ll always be tributai like the rest of us.’

‘You’ve got it all wrong, berth-friend,’ Ghelsa said, stepping forward. She picked up the metre-long multi-tool she had left beside the door. Its considerable weight was nothing in her grasp, her own significant musculature assisted by a tracery of exo-skeletal cable sealed into her flesh.

‘How about on the downshift?’ Ghelsa asked, feeling the urge to reconcile even though, rationally, she knew she had done nothing wrong.

‘Just go and fix that manifold array,’ muttered Notasa, stepping away from the hatch. ‘Maybe we’ll see each other later.’

Already anxious about the time she had spent playing Omnissekh, Ghelsa aimed a kiss towards Notasa’s cheek, but he retreated, scowling. The spindle-wrangler ducked out into the corridor, stepping out from the relative cool and quiet of the coolant exchange access.

The sound had always been there, of course, and most of the time Ghelsa barely registered it. For three and a half years – Martian-adjusted standard – she had lived on or around the Casus Belli. Since achieving adulthood her existence had been dedicated to the services of the Machine-God, as dictated and directed by the Adeptus Mechanicus.

Yet there were times, like now, when she moved from one part of the downdecks to another and listened again, her attention drawn back to the nuances of her home. There was the obvious noise, the clatter and clank, the grinding of the massive gears, the low pulsing of the reactor links. Any neophyte could identify them within a matter of days. It was the deeper, quieter sounds that were the most welcoming. The hiss of coolant as a spin-off drained heat down from the main reactor exchanges. The ever-present gurgle of waste water falling through the cisterns beneath the starboard decks. The thrum of the pumps inside the capillary towers that took lubricant up to the immense hellstorm cannon.

She stepped into a pass-niche as a trio of sweat-slicked mattokhai labourers dashed past, the uncoupled pieces of their thrum-hammer over their shoulders, power cables swishing like monkey tails. Droplets of perspiration trickled down her cheek and the side of her nose, the heat and humidity of the core-ways as oppressive as the first-hour labour-sermons of the tech-priests. Ghelsa made her way along the corridor, the metal dappled by the pale yellow glow of lumens behind wire cages, in places splashed by the green or amber of a system registry lamp through a grimy inspection plate.

Through the mechanical din she detected organic sounds. The hacking cough of Merkadoa, who was still waiting on a promised new lung after an incident with the trash conflagrator’s secondary exhaust. Chatter. Ceaseless, unintelligible sounds occasionally punctuated by a spurt of screeching, clicking binaric from a passing enginseer, and ever so occasionally the artificially modulated tones of a higher-ranking tech-priest descended from the God-decks to conduct an inspection or investigate a delayed report.

Just as her constitution had adapted to the clammy conditions, and her ears were attuned to the sonic flexes of the internal society of the downdecks, so her eyes were well accustomed to the gloom. With her other senses guiding her unconsciously to her destination, Ghelsa was free to wander almost at will, knowing instinctively where to step around open hatches, dodge across ladder holes and duck beneath intervening cables and piping. It was mid-shift and most of the others were at their stations, the narrow walkways and transit-bridges populated only by occasional movement.

Through the doors and arches she passed she saw other tributai at their work, blotches of white through clouds of vapour. She saw smears of paleness in dark maintenance bays or clustered around the fully robed enginseers as some fundamental duty was enacted or a Principle of Conduct passed on for the appeasement of an itinerant fragment of Casus Belli’s all-encompassing machine-spirit.

Thoughts fixed on her job in the lowest decks, Ghelsa moved on.

The command module dominated the inside of the Imperator Titan’s head. Two massive eye-like screens relayed realtime feeds from thousands of augurs across the war engine, creating a complex representation of the surroundings in both visual and noospheric frameworks. Exasas not only saw the doors of the barge’s hangar as a human would, but knew exactly the composition of the metal and the weight and torsion values, as well as a welter of data on atmospheric pressure, temperature and other tertiary readings. It was the closest ve could come to feeling as the Titan felt without the benefit of the mind impulse units to organically share the sensation.

The princeps senioris’ main command throne sat on a dais towards the back of the chamber, looking down at the three moderati positions. Each was a reclining chair beneath a tangle of cables that would connect to the incumbent’s MIU systems. On the left, Moderatus Haili controlled the energies of the plasma annihilator; the twinned position on the right for the hellstorm cannon was the seat of Moderatus Rasdia. The two of them made for their couches, handing their interface helms to the tech-priests attending each station.

Moderatus Gevren was stationed between them, responsible for the activation and monitoring of the rest of the Casus Belli’s considerable arsenal – main battery, defence laser, anti-aircraft systems and point defence weaponry.

In most Titans the moderati were in sole control of their armaments, but the guns of the Casus Belli were too large for a single moderatus to control – or in the case of Gevren, too numerous. They were aided by gunnery teams with the weapons themselves, mostly slaved servitors that acted as extensions of the moderatus’ will, each team overseen by a trio of tech-priests to ensure their continued operation.

Between the princeps senioris’ throne and the moderati, and along the outer walls of the chamber to either side, the tech-priests addressed their panels and interfaces. The noosphere crackled with their intent, linking their minds even as dataports and mechadendrites connected them physically with the Omnissiah’s greatest warrior.

Exasas’ position was just behind the moderatus prime, from which ve could link into the noosphere signals related to the skitarii systems and personnel. Connecting to the cogitators, ve felt the company of warriors settling into their barracks chambers within the two leg-citadels, and several more platoons likewise preparing for departure in the battle stations of the akropoliz.

Ve could feel the skitarii as a homogeneous force, or relay part of vis strategic consciousness into one of a hundred and forty-two separate organisms via their noospheric cortical weaves. In a split second the magos dominus could switch to the individual view of a particular warrior – ve picked one on a whim and watched the faces of the three soldiers opposite through vis chosen receptacle’s eyes. At the same time, cyclical simulators tracked other battle-pertinent datafeeds, for the moment semi-dormant and reliant on the last orbital data uploads ve had taken just before boarding.

Little had changed and the princeps senioris’ assessment that there was only a small probability of infantry engagement remained accurate. Their mission was to break the heretek lines defending a citadel and break into the mountain passes, spearheading the full battle group. It was an overwhelming use of force, mounted not only to sweep aside the barriers to the advances of the Astra Militarum and other skitarii armies, but also to demonstrate the folly of further resistance to the will of the Omnissiah.

Exasas played back vis memory-store of the prime dominus’ instruction, passing it through vis thoughts and into the minds of vis subordinates.

Exasas [broad trans/concept/loop]: <Az Khalak will burn by nightfall.>

A tremor ran through the noosphere, a throb of intent that channelled into every datafeed. Exasas turned one of vis sensory inputs to the princeps senioris and saw that she wore her helm, its MIU cables linking her to the essence of the behemoth she would guide into battle.

Sharing her thoughts, made whole by the metaphorical sacrifice of her consciousness, Casus Belli started to rise from its slumber. The leading edge of a powerful wave of awareness touched upon the noosphere and digital systems flickered into wakefulness, caressing Exasas’ sensory inputs. Ve heard a sigh from Iealona’s parted lips, grunts and murmurs emanating from the moderati as they were joined to the machine-spirit.

Exasas could not comprehend how it might feel to be one with the god-machine. Ve could interpret the millions of data-signals and extrapolate sensory curves for eternity and still not know what it was like to share physicality with the might of the Imperator. Only Iealona and her predecessors had shared that singular, glorious experience.

A visual feed highlighted a glint of amber light on the head of the bone cane leaning against the side of the command throne. While monitoring the other developments, Exasas allowed a portion of vis thoughts to consider the implications. Princeps senioris, and to a lesser extent moderati, had shortened lifespans due to their connections with the immortal spirits of the Titans. For the Machine-God’s warriors to live, their mortal components had to shed a little of their span. Even as her frail body was failing, the princeps senioris was able to clad her thoughts in the armour and power of the Imperator. She could not escape her mortality – in fact she hastened it – but in the time she had, she could share the body and thoughts of an immortal.

As an exchange, it was not without merit.

The noosphere flared with reports and counter-signals, confirming the readings of the plasma reactor, the online status of motivation and balance systems and the networking of the mind impulse units with the moderati and princeps senioris.

Exasas sent vis own confirmations, having spared a moment to check that all skitarii personnel were aboard and at their stations.

Awoken, the spirit of Casus Belli yearned to be free of the confines of the barge. With a final flurry of data exchanges, the tech-priests allowed the reactor to come to full power and the MIU to flow unhindered between the circuits of the Imperator and the synapses of its princeps senioris.

Casus Belli lived.

In semi-aware fashion, Ghelsa traversed the main lateral passages of the Imperator Titan’s downdecks, coming upon the third service shaft from the rear. The mechanism was nothing more than an old autoloader, repurposed by the engine crew for human cargo. Two shafts contained a continuously slow-moving chain, every few metre-long links interspersed with a metal platform just large enough for a foot.

Ghelsa waited at the drop-shaft until the next platform rattled into view and then quickly stepped out, bare foot on the plate, one arm wrapping through a chain link. The descent carried her past the wall of heat that emanated from the sealed reactor decks into the comparative gloom and cool of the motivator and traction assembly. So much quicker than negotiating the monkey-ladders.

She deftly jumped off at the main actuator array – a huge gearing system that powered the left hip joint of the forty-metre-tall war engine. Artificial fibre bundles each thicker than her waist vibrated with latent power while the hiss of immense pneumatics punctuated a steady grinding of metal on metal. The entire compartment shook, a constant tremor that pulsed through the nervous system. Just a few metres away, immense cog teeth that could crush her in moments knitted together, the piercing screech of their contact setting her teeth on edge.

She immediately saw the dysfunction, her experienced eye drawn to the ever-so-slight wobble of a tertiary drive shaft linking in to the main coupling. Here, close to the fulcrum of the hip’s movement, there was little sense of vertical motion compared to the upper downdecks or the heights of the templedecks. The floor rose and lowered laboriously like a ship on a lazy ocean swell. The turn of the gears was a far better indication of the Titan’s stride. At the moment it was at a comfortable cruising pace, perhaps four strides per minute, each step covering some fifteen metres of ground. They had been in motion for a while – since before the dice game had started – and she reckoned the landing barge was now several kilometres behind them.

There was a pause of three and a half seconds at the apogee of the stride during which cantilevers and secondary gyros compensated for the shift of weight from one system to the other. Ghelsa waited, bobbing lightly on the balls of her feet, adjusting the wrench head of the multi-tool to the required bite.

Just as the drop-gear shifted into place, some twenty metres below her the Titan’s massive foot settled into the ground. Ghelsa sprang into action. She pulled herself up onto the box of the main drive train and latched the head of the multi-tool around the errant fitting. Her exo-muscles creaked as she pulled back, one foot braced against a cross-stanchion. One turn. Two… The second pull seized at the halfway mark, fully tightened.

Ghelsa loosened the tool, pulled it free and jumped back to the deck with half a second to spare. She watched the drive system engage again, and listened for an erroneous clatter. The wheel spun smoothly, its low growl testament to a job completed.

‘The Machine-God blesses,’ she intoned, lifting the multi-tool to touch the godplate upon her brow. ‘In praise of the Omnissiah our duty is done.’

She cast her eye around for any other small fixes that might be performed while she was there, but all seemed to be running well. The tributai took a deep breath. The air was thick with lubricant and incense, a mix she had come to know and adore in her time aboard the Casus Belli. Those of different homes might long for the scent of fresh bread or the animals in their pens, but for Ghelsa it was the machine smells that made her feel safe.

By the rattle of the lifter chain she knew a platform was coming around. She stepped back into the alcove without looking, her foot coming upon the plate just as it passed the level of the floor.

Taken up once more, she wondered what other tasks awaited her and started to hum a slow inkanta in her contentment.

Two decks up, just below the reactor exchanges, movement and alien sound caught her attention. Through the grille of the deck above she saw a huddle of people wearing the red-lined cloaks of the hyperezia, the tech-priests’ enforcers in the downdecks. Their grunts and shouts were audible above the noise, and Ghelsa could clearly see fists and short staves rising and falling – they were beating someone.

She was not one to interfere in the disciplining of another, but that it took place here in the dark rather than before the peers of the offender struck her as odd. Ghelsa alighted on the deck a few metres away from the gaggle, noting the blood on their knuckles and mauls.

‘What’s happening here?’ she called out.

One of the hyperezia cast a glance over his shoulder, bearded face half shrouded in shadow.

‘Get gone, oil-rat,’ snarled the henchman.

In moving, he revealed something of the victim. Ghelsa glimpsed a blood-spattered hand and a white sleeve, but saw no mark upon the wrist.

‘Ho there, that’s a tributai!’ she shouted, taking another step.

‘He’s a heretek, is what he is,’ one of the others spat back, her face contorted in anger. ‘By word of the moderatus prime.’

Invoking the rank of their superior only worsened their case. It all seemed out of place.

‘You’re killing him.’

‘Want some as well?’ growled the first of the watchmen, lifting his baton towards her.

Ghelsa covered the distance in three strides, the last of which was accompanied by the upswing of the multi-tool. Powered by momentum, thick muscle and reinforced armature, the heavy metal implement struck the hyperezia’s chin at full speed.

Bone splintered and the guard toppled back, blood spraying from his ruined mouth.

Ghelsa was no warrior, but her augmented body gave her strength enough to compensate for a lack of skill. Her next blow shattered the baton raised to ward it away and smashed into the chest of the man holding it, hurling him backwards with a broken breastbone. A fist glanced off her cheek – nothing worse than she had suffered in one of her spats with Notasa or a fight in the narc-hide. Her return blow to the woman’s gut lifted the hyperezia off her feet, the air exploding from her lungs in a hoarse whistle. The guard crumpled, gasping, while the remaining three backed off, their rods held warily before them.

The spindle-wrangler glanced down at their victim. He was caked in blood and garbed in the robe of a tributai clerical worker – one of the log keepers, perhaps. He rolled to his back with a groan, revealing a face swollen about the eyes and mouth, his cool beige complexion looking jaundiced in the poor light. She didn’t recognise him.

Ghelsa hefted the stranger up onto her shoulder, thrusting the multi-tool threateningly at the others.

‘Leave it be. Tell Gevren the deed is done and no more need be said.’

The hyperezia did not look convinced, but they made no further effort to molest her as she backtracked towards the clanking chain of the ascender shaft.

With a quiet groan, the man roused as she lowered him, holding his body close to hers while she waited for the next platform to come around. He peered at her through the slit of a bloodshot grey eye, child-like against her mass.

‘Danger,’ he croaked.

‘No, you’re safe now,’ she assured him, moving her arm protectively around his shoulder as she darted a glare at the guards, who were tending to their own injured. ‘Well, relatively safe.’

‘All of us,’ whispered the man. ‘Hereteks.’

The platform rattled past and Ghelsa missed it, distracted by this statement.

‘The princeps is a traitor,’ the man continued wheezily, every word a clear effort through the pain. Whoever he was, Ghelsa admired the sheer will it must have taken for him to remain conscious. ‘Will doom… us all.’

‘Says who?’ Ghelsa was startled, but she had enough presence of mind to drag her companion into the lift when the next platform appeared.

The man said something else, but it was lost in the noise of the conveyance.

‘What was that?’ Ghelsa said, raising her voice. He pushed closer and she bent an ear towards his bloodied lips.

‘I… I am an inquisitor.’
