It is a time of legend.

The galaxy is in flames. The Emperor’s glorious vision for humanity is in ruins. His favoured son, Horus, has turned from his father’s light and embraced Chaos.

His armies, the mighty and redoubtable Space Marines, are locked in a brutal civil war. Once, these ultimate warriors fought side by side as brothers, protecting the galaxy and bringing mankind back into the Emperor’s light. Now they are divided.

Some remain loyal to the Emperor, whilst others have sided with the Warmaster. Pre-eminent amongst them, the leaders of their thousands-strong Legions are the primarchs. Magnificent, superhuman beings, they are the crowning achievement of the Emperor’s genetic science. Thrust into battle against one another, victory is uncertain for either side.

Worlds are burning. At Isstvan V, Horus dealt a vicious blow and three loyal Legions were all but destroyed. War was begun, a conflict that will engulf all mankind in fire. Treachery and betrayal have usurped honour and nobility. Assassins lurk in every shadow. Armies are gathering. All must choose a side or die.

Horus musters his armada, Terra itself the object of his wrath. Seated upon the Golden Throne, the Emperor waits for his wayward son to return. But his true enemy is Chaos, a primordial force that seeks to enslave mankind to its capricious whims.

The screams of the innocent, the pleas of the righteous resound to the cruel laughter of Dark Gods. Suffering and damnation await all should the Emperor fail and the war be lost.

The age of knowledge and enlightenment has ended.
The Age of Darkness has begun.

Peace. The word was meaningless to him. As far back as Loken could remember, he had never known any state of being that could equate to the concept as it was now explained to him. The word had served as a talisman once, back when the universe made sense, an ideal for which to strive. An end of war and the fulfilment of the task for which he and his brothers had been created. He was of the Legiones Astartes, a warrior born and bred, wrought in the Emperor’s gene-labs with forgotten alchemy and unknown science.

What could a being who knew only how to kill understand of peace?

Yet here in the garden, Loken felt something close to it.

Warm sunlight shone in a flickering blue sky, entoptically rendered on the curved inner face of the dome, yet no less pleasing for its artifice. Pictographic clouds drifted in a non-existent breeze, and birdsong chirped from artfully concealed vox-grilles worked into the garden’s structure.

The garden was composed of rough ouslite slabs laid like giant flagstones, arranged around a series of square, shallow basins of crystal-clear water. Lilies and bright flowers flourished in rock pools fed by a branch system hived from the brass tower’s reservoirs. Ferns and weeping trees caressed the water’s edge, and something in their placement stirred a long-buried memory, though one Loken found himself unwilling to examine too closely.

He made his way through the garden, enjoying the quiet and the warm scents of living things. Water gurgled over an ornamented arrangement of smooth rocks, and fell in a spuming waterfall that tumbled into a miniature lake of glitter-gold koi. Curved steps led down to neat rows of planting beds, where the seeds Loken had planted were already beginning to grow.

Clad in a long chiton of unadorned grey over a tan bodyglove with plastek-seals over his armour interface sockets, he was armed only with a few gardening tools hanging from a leather work belt. Loken walked with the heavy steps of a mourner at a memorial, his shoulders broad, but hunched, as though they carried the weight of the world upon them. His features were broad and flat, made blunt by war and drained of joy by betrayal.

Yet as he surveyed the green shoots pushing their way out of the dark soil to the light above, the thinnest trace of a smile came to his lips. Bred to kill, not to care, it gave Loken a sense of the wonder of creation. By his hand was this universe in miniature flourishing.

His eyes narrowed as he saw one corner of the planting beds green with an altogether unwelcome growth of weeds and enveloped with a spun sugar gleam of gossamer-fine spider webs. Loken unhooked a trowel from his belt, one that was entirely too small for his grip, but which he handled with surprising delicacy. He could have asked for tools better suited to his transhuman scale, but the forges of the brass tower were tasked with the production of more important things than mere gardening implements.

Like any warrior, he learned to make do with what he had.

Loken knelt on the corner slab and swept away the spider webs with his hands. Arachnids emerged from hiding at the disturbance, and he flinched at the sight of them. The multi-limbed creatures sparked a memory fragment in Loken: a war of gruelling attrition, hard-fought victories and a glorious time when gods did not make war on one another.

He couldn’t place the memory, but that was nothing unusual. The madness that almost consumed him on Isstvan III had left scars that were slow to heal and quick to flare in jagged pain. The spiders contented themselves with baring their fangs then retreating into their subterranean lairs, and Loken felt an irrational hatred of the creatures swell in his heart.

He dug into the soil with vicious jabs, laying the weed-roots on the slab beside him and seeking to drive the spiders out. This section was particularly overgrown with parasitic plant matter, which was in the process of draining the goodness from the soil and choking the life out of the crop growing here. The seeds had been sown before he had found the garden, and had withered once already, but with his patient attention, the garden had bloomed once again, brighter and more vital than ever.

The previous custodian of this biodome had allowed it to grow wild, neglecting the task of prudent weeding and maintenance. He had since learned that Sister Elliana was long dead on Prospero, and no one had taken up her duties in the biodome. An understandable lapse. The maintenance of a space that existed for purely aesthetic reasons would be seen as wasteful.

And in times of war, nothing wasteful could be tolerated.

Loken had found the biodome by chance, staring vacantly through the armourglass window of the orbital shuttle bringing him back to Luna. He had spent the journey back from the Caliban fiasco in contemplative silence, isolating himself from the crew of the nameless vessel that crept into the Dark Angels domain before slinking away like a thwarted thief.

The abject failure of the mission weighed heavily on Loken, and he had struggled with his part in it through the long, cold nights in the dark heart of the vessel. He was a warrior who had turned his back on war, a man without colours or a Legion to call his own. In the depths of his despair, he had believed himself to be a Legion of one.

Nathaniel Garro had shown him that was no longer the case.

He no longer fought alone, but he cared nothing for the warriors who stood with him. The brotherhood of his former life was no more than a ghost memory now. None of the easy banter he’d shared with Vipus and Torgaddon leavened the times between engagements, only cold hard mission briefings and grim talk of their shadow war.

A shadow war in which he no longer wished any part.

Seated in the back of the shuttle with Iacton Qruze, Loken had felt cramped and claustrophobic, deeply uncomfortable at sharing so confined a space with another refugee from his Legion. Qruze had sensed his discomfort and known enough not to intrude on Loken’s solitude. Only as the shuttle banked during its crossing of the Sinus Honoris did Loken notice the glinting diamond of the biodome on the edge of the Mare Tranquillitatis. No sooner had he blink-clicked the selenographic coordinates than the dome was lost to sight as the shuttle spiralled in on its final approach to the Somnus Citadel.

Built on the haunches of the Palus Somni, the fortress of the Silent Sisterhood rose from the uneven, rocky terrain on the north-eastern edge of the great basin. A soaring tower of brass and crystal, its myriad docking bays were arranged one atop the other like the lairs of undersea creatures in a spire of coral. Their scale was impossible to judge, but Loken knew each was large enough to accommodate the sisterhood’s nigh-invisible black ships. Unlike the rest of Luna’s surface, the surface of the Palus Somni was the shade of bleached tan, its hue different from any of the moon’s other plains or mountain regions.

Dorn had been waiting for them.

Already appraised of the mission’s outcome by astropathic means, the primarch of the Imperial Fists had, nevertheless, taken time from the dismantling of his father’s bejewelled palace to hear the ill news from Caliban first-hand. Loken had seen Lord Dorn’s hope that the imperfect medium of astropathic communication had missed some subtle nuance to Qruze’s report, some sign that the Lion’s warriors of Caliban could be counted on to rally to the Emperor’s banner.

Dorn would return to Terra none the wiser, and Loken’s heart had broken at disappointing him.

Loken remembered the first time he had seen Rogal Dorn, deep in conversation with the Warmaster. He had seemed titanic then, a demigod built to match the strength and prowess of Horus himself; no small admission for a warrior of the Luna Wolves to make. Clad in golden plate and seemingly carved from the solid core of a mountain, the primarch had made Loken feel like a specimen pinned to an examination table, scrutinised by a being who understood everything about him in a heartbeat.

Dorn was still that demigod, but Loken saw he was somehow… diminished, as though the burden he took upon his shoulders was growing heavier by infinitesimal fractions every second. Like the trickle of water that over millions of years splits the mountain, Dorn’s role as Terra’s Praetorian was one that would already have crushed a lesser being.

How long might it take to crush a warrior like Dorn?

That debriefing had been kinder than the first to which he had been subjected. He had been brought to the Somnus Citadel as a broken, wretched thing; a madman Nathaniel Garro had dug out of the ruins of Isstvan III. Loken now understood that he had been closer to death during that interrogation than any other time in his life, though those who wished him gone did not come with blades, bolts or orbital bombardments; they came with doubts and fear and suspicion.

Was he to be trusted? Could anyone – even a Space Marine – have survived what he survived? Had he been left in the ruins by their enemies for Garro to find? Was Garviel Loken a ticking time bomb left by Horus, primed to inveigle himself into the Imperial ranks only to wreak untold havoc in the days to come?

No one knew for certain, but powerful men had spoken for him: Garro and Malcador for certain, and – Loken suspected – Lord Dorn himself. But others – he never knew their identities – declared him a danger, a potential spy or worse. What followed was an indeterminate period of pain and misery, inflicted on his body and the depths of his mind to seek answers to those questions.

That he still lived was not seen as definitive; merely that his interlocutors hadn’t found anything damning enough to go against the wishes of the Regent of Terra and the Emperor’s golden-armoured Praetorian.

The Caliban mission had been authorised by Lord Dorn and was… what? Penance? A test of his loyalty? At every stage of that mission, Loken had the sense of a pistol being aimed at his head. He had understood in the way that only men of violence know, that Qruze was to be his executioner if his fealty proved false.

With statements delivered to Dorn and numerous faceless functionaries, Loken had followed his snapshot coordinates to the biodome, taking the rusting hulk of a Cargo-5 onto the Lunar surface, past ancient ruins of the first colonies to spring up on Terra’s moon and a site marked with an eagle banner that commemorated some great achievement of a distant age.

That the dome was still functional was Loken’s first surprise. That life still flourished within was his second. Overgrown to the point of needing a slash and burn campaign to return it to any form of order, Loken had felt a measure of calm in the flickering light of the glitching entoptics. Blue skies shimmered above, broken by portions of starlight and tantalising hints of the iron-clad world above. The riotous foliage grown to gigantic size reminded him of a world he had once trod, a place of blistered skies and thick-bladed stalks of fibrous material. It was a world that bore a name of violent death, but he found he could no longer remember it.

Loken had taken it upon himself to restore the garden to its former grandeur.

Kill for the living and kill for the dead…

Those had once been the words by which he had lived.

He thought he might even have sworn an oath to that effect once. He’d seen that moment as if from the point of view of an observer, though he didn’t know how that could be possible. Had he experienced that moment at all or was it a phantom pseudo-memory?

A name sighed upwards into his consciousness at the thought of that moment – Keeler – but it held no meaning for him any more. Was it a person or a place?

Loken no longer knew and, in truth, no longer cared.

Once a killer, now he would be a custodian of living things.

Spiders crawled from the dark earth, and Loken crushed them where he saw them. Some, the smarter ones, kept out of the light and dug down deeper, but Loken’s trowel scooped them from their hiding places and killed them anyway. There would be nests beneath the soil, and he needed to kill the offspring of the spiders too. Anything less than total extermination would simply allow the canker beneath the surface to grow unseen until it was too late to stop.

‘You know that if you kill all the spiders, you’ll just inherit their work, yes?’ said a voice drifting across the koi lake.

Loken looked up, instantly alert. The speaker stood thirty metres away in the shadow of the weeping trees at the lakeside, but his powerful voice had not diminished in the intervening distance.

‘Why do you say that?’ he asked.

The figure stepped from the shadows to kneel at the water’s edge, and Loken saw he had the bulk of a legionary, though not one he recognised. These days, most faces were a blur to him, an assemblage of features that held no meaning, bereft of the visual cues that could differentiate them. He had taught himself mnemonics to recall the people that now mattered in his limited sphere of existence, but this warrior conformed to none of his self-imprinted memes.

And yet there was something maddeningly familiar to this figure.

The entoptics woven into the dome’s structure flickered and a perfectly circular reflection of Terra glimmered in the black mirror of the water. Loken felt his hostility at this intrusion into his domain lessen at the sight of the planetary bauble, as though it reminded him of a once perfect moment never to come again.

‘Spiders kill the aphids and other pests that devour the plants,’ said the man, skipping a flat stone across the lake and grinning broadly as it smacked on a rock on the other side. The reflected image in the water broke into splinters of pale light. ‘You might not like the look of them – they’re not too pretty after all – but they’re waging a war for you even if you can’t see it.’

The man’s tone was laconic, but Loken saw past it to the dangerous core beneath, though, oddly, he felt no threat from him.

‘Do I know you?’ asked Loken, rising from his labours and wiping his knees of dirt.

‘You don’t recognise me?’

Loken hesitated before answering. ‘I might if you came closer.’

‘I think I’m fine as close as we are for now,’ said the man, circling around the pool. He bent to choose another flattened stone from the lakeside and turned it over in his hands. Satisfied with its heft, he skimmed it across the water towards Loken. The stone bounced and skipped across the surface of the lake before striking an angled rock and arcing into the air.

Loken reached up to catch the stone, but it smacked into his palm and bounced away before he could close his fingers over it. The pain was momentary, but it galled him that he’d failed such an easy feat of dexterity. A dirty purple bruise formed on his skin.

‘You used to be quicker,’ said the man.

‘I used to be a lot of things,’ replied Loken.

‘Very true,’ agreed the stranger.

‘You know me, but you still haven’t told me who you are,’ said Loken. ‘If you’re another of Malcador’s “counsellors” then you should turn around and leave. I owed it to Lord Dorn to go to Caliban, but I’ve no time for the Sigillite’s half-truths and subterfuge. I no longer want a part in his schemes within schemes, so he should stop sending his lackeys for me. Though I should be grateful that at least he’s sent a legionary this time.’

‘He sends mortals to try and understand the mind of a legionary?’ said the man, with a shake of the head that conveyed his amusement at such an idea. ‘They really don’t understand us at all, do they? But to set your mind at ease, I’m not here to summon you and I’m no counsellor, though I’ve dispensed my share of battlefield wisdom. Bolter bon-mots, you might call them.’

The quip seemed to amuse the man and he laughed aloud, though Loken was beginning to tire of the stranger’s obtuse answers. He hooked the trowel to his belt and followed the path that led to the steps cut into the rocks by the waterfall.

‘Leaving already?’ asked the man, moving along a parallel path.

‘If you won’t even tell me your name then I have no interest in continuing this discussion.’

‘Is my name really that important?’

Loken paused at the bottom of the steps. He felt that he should know this man’s name, and that, yes, it was important he know it. It felt as though much depended upon that revelation.

‘How can I trust you if I don’t know your name?’

‘You already know it. Why should I tell you it again?’

‘I don’t know it,’ spat Loken, his hands curling into fists. He was unarmed, but a warrior of the Legions had no need of weapons when it came to killing.

‘You do,’ said the man. ‘You’ve just forgotten it.’

‘Then I’ve forgotten it for a good reason.’

‘No,’ said the man. ‘For all the wrong reasons. It was the only way to survive on Isstvan Three, but you’re not on Isstvan Three any more. The Warmaster tried to kill us there, but he failed. Well, for one of us at least.’

The entoptics flickered again, and something on the underside of the dome’s cupola blew out in a shower of sparks. They rained down onto the water, fading as they fell, and once again the reflected image of Terra appeared on the lake’s surface as the skin of the dome became transparent.

‘You were on Isstvan Three?’ said Loken as the figure emerged into the glow from the lake’s surface.

A cold hand clenched his heart as the man’s previously unknowable features resolved into those of a brother from a previous life.

‘I still am,’ said Tarik Torgaddon.

They sat on the ridge overlooking the lake, two brothers separated by a yawning gulf of regret and mortality, yet Loken felt as if no time at all had passed since last they had spoken. Torgaddon reclined upon an upright flat stone topped with a crescent arch and toyed with a loose thread on his robes that frayed the more he pulled at it.

‘How are you here?’ asked Loken.

Torgaddon shrugged. ‘You tell me.’

‘I saw you… I saw you die,’ said Loken. ‘Little Horus killed you.’

‘Aye, I think he did,’ said Torgaddon, pulling down the collar of his robes and probing his neck with his other hand. The fingertips came away red, and Torgaddon licked the blood away. ‘Still, could be worse.’

Loken wanted to laugh at such a ridiculous statement.

‘How,’ he said, ‘could it be worse?’

‘Well, I’m here, aren’t I?’ said Torgaddon. ‘Talking to you.’

‘And how exactly is that possible? The dead don’t rise from their graves.’

‘I seem to recall something of that on Davin’s moon,’ pointed out Torgaddon.

‘I suppose,’ agreed Loken. ‘In fact I seem to remember hauling your sorry arse out of a swamp as a bunch of dead men were dragging you down.’

‘You see? These days, death isn’t the handicap it used to be.’

‘Don’t be glib,’ said Loken. ‘I don’t know what caused the dead of the plague moon to fight. A pathogen, or some cerebral parasite maybe.’

‘Come on, you don’t really believe that,’ said Torgaddon. ‘You’ve been reading too many of Sindermann’s old books again, haven’t you?’

‘Maybe I don’t believe that, but I know people who had their heads cut off don’t get up and start walking around and talking to old friends.’

‘I’ll admit it’s a puzzler,’ agreed Torgaddon.

Loken reached out to touch Torgaddon’s arm, and the limb he grasped felt as real and as solid as his own. He felt the rough fabric of his brother’s sackcloth robes and the steel-trap strength in the musculature beneath. His hand came away black with ash, and he rubbed it clean on the grass.

‘Am I still on Isstvan Three?’ asked Loken. ‘Did I die there too? Did Garro kill me, or am I still alone, still Cerberus?’

‘Cerberus?’

Loken shook his head, embarrassed. ‘A war name I think I took for myself.’

‘Guardian of the underworld,’ said Torgaddon. ‘Appropriate enough, I suppose.’

‘I thought you’d know that.’

‘I know just what you know,’ said Torgaddon. ‘And what you know is… patchy, shall we say?’

Understanding dawned on Loken. ‘Ah, so you’re a figment of my imagination? Some memory my damaged mind has conjured up.’

‘Maybe,’ agreed Torgaddon. ‘You straight up and down types do like to punish yourselves.’

‘Punish?’

Torgaddon nodded and leaned forwards. Loken caught the pungent reek of his brother’s blood and the choking dust of smashed building parts mixed with the chemical stink of explosives and the burned metal smell of war. He gasped as he relived the moment of his awakening, trapped beneath thousands of tonnes of debris and wondering how he was still alive.

‘Why else would you think of me except to punish yourself?’ asked Torgaddon, staring right into the heart of him. ‘You let me die. You watched Aximand take my head, and you didn’t stop him. He killed your closest battle-brother and you didn’t hunt him down and kill him for what he did. How can you call yourself my friend while that treacherous bastard still breathes?’

Loken pushed himself to his feet and walked away from Torgaddon, standing at the edge of the waterfall and staring down into the water forty metres below. The fall might not kill him, but the rocks at the bottom were like the sharpened teeth of a half-submerged leviathan and would certainly break a good many of his bones. How long would it be before anyone came to find him here? Long enough for the water to turn red with his blood? Long enough for him to die?

‘I wanted to hunt them all down. I wanted to kill every last one of them,’ he said at last. ‘But… there was no way off Isstvan. Everyone was dead. I was trapped on a world of death.’

‘The dead who rose up, I might point out,’ said Torgaddon.

‘I… I lost my way for a time,’ continued Loken as if he hadn’t heard Torgaddon. ‘I was so consumed by the need to kill that I lost sight of what it was I needed to kill.’

‘Then Garro came and brought you back.’

Loken nodded. ‘He convinced me I still had a duty, a debt to pay, but this isn’t the fight I was made for. I can’t fight in the shadows, Tarik. If we’re going to beat the Warmaster, then it has to be out in the open. He has to be seen to be defeated, so that everyone knows it.’

Torgaddon got up and smoothed down his robes, the fraying thread still hanging from his sleeve.

‘You said “if” you beat the Warmaster,’ said Torgaddon. ‘You don’t think it can be done?’

‘You were a Luna Wolf, Tarik,’ said Loken, rubbing a hand across his face as a tremendous wave of weariness swept through him. ‘You know as well as I do that he’s the most dangerous man in the galaxy. There’s a reason Horus was made Warmaster and not any of the others. He’s the best at what he does, and what he does is make corpses of his enemies.’

‘So that means you shouldn’t fight him?’

Loken shook his head. ‘No, of course he has to be fought.’

‘Just not by you?’

‘What do you mean?’

Torgaddon ignored Loken’s question and spread his arms, turning on the spot to encompass the entirety of the garden.

‘You’ve worked wonders here, Garvi,’ said Torgaddon. ‘It’s just like I remember it.’

‘What is?’

Torgaddon cocked his head to one side and stared quizzically at him. ‘You really don’t see it?’

‘See what?’ said Loken, growing tired of Torgaddon’s constant evasion.

‘This place? You don’t recognise what you’ve built here?’

‘No.’

‘Sixty-Three Nineteen?’ said Torgaddon as though teasing the memory out, like a timorous animal coaxed from its burrow by soft words and the promise of food. Loken looked down at the garden, now seeing it for what it was: the square shallow basins surrounded by flagstone pathways, the weeping trees and the bright flowers gathered at the water’s edge. Memory surged, and he gasped as the full force of it tore into the fractured synapses of his mind.

When he’d first come here, none of this had existed. The enclosed biodome had been a tangled, overgrown mess that looked like it needed a flamer team or a destroyer cadre to tame it. But Loken had rebuilt it, hacking away the fibrous masses of dying flora and dumping it outside the dome. Working in his battle armour for days at a time, he’d fought the unwinnable fight against the rampant overgrowth of weeds and uncontrolled expansion of climbing plants. And he had brought the garden back to life, using a well-borer drill to cut giant flagstones from the Mare Tranquillitatis and hauling them inside to lay the paths around the pools he’d dug.

Everything that now existed within this dome had been wrought by his hand, and now he saw that, he understood why every little thing was freighted with familiarity.

‘The water garden,’ said Loken, tears misting his eyes. ‘This is where I took the Mournival Oath.’

‘And do you remember what you swore?’ said Torgaddon, putting a hand on Loken’s shoulder. ‘You pledged to serve the Emperor above all primarchs. To uphold the truth of the Imperium of Mankind, no matter what evil might assail it. To stand firm against all enemies, alien and domestic.’

‘I remember,’ said Loken.

‘You swore to be true to the Mournival to the end of your life,’ said Torgaddon.

‘The Mournival is broken,’ said Loken. ‘Ezekyle and Aximand saw to that.’

‘Very well, to the ideals of the Mournival then.’

Loken nodded. ‘This was the last moment I felt we were on the verge of something incredible.’

Torgaddon. ‘Aye, it was. And now you know that, you know you can’t stay here.’

Loken’s mind was afire with all that came after that moment: the war on Murder; the blood spilled from misunderstanding upon the home world of the interex; the horror of Davin; the slaughter of the Auretian Technocracy; and the final, monstrous betrayal on Isstvan III. He’d known all this, he’d always known it, but had found a way to keep it locked away in the depths of his mind.

Loken dropped to one knee, overwhelmed by the surge of suppressed memory.

‘I remember it all,’ he whispered. ‘I didn’t want to. I tried to forget, but it looks like I can’t.’

‘It’s like the dead things at the bottom of the sea,’ said Torgaddon. ‘Maybe they were tied to anchors or boulders, but somehow things got rotted up and those dead things are floating up to the surface. We never knew they were there all along, but we’re seeing them now.’

Loken looked up at Torgaddon, who held out a hand to him.

‘You’ve hidden here and lied to yourself for too long, Garvi. It’s time you got back in this war, whether you fight in the shadows or the light of day. Right now, the Imperium has foes in both. You’re going to have to go down the hole and see how dark it gets, and I warn you it’s going to get very dark indeed before this is over.’

Loken took Torgaddon’s hand and let the big man pull him to his feet.

‘I told you, I’m not built for this kind of fight,’ he said.

‘You’re built for every kind of fight,’ said Torgaddon. ‘You know this and you need to stop thinking as if the Imperium is on the back foot. You’re a Luna Wolf, and nothing is more dangerous than a cornered wolf.’

‘So you think we’re cornered?’

‘All right, maybe that wasn’t the best expression,’ admitted Torgaddon. ‘But you know what I mean. Strong enemies know when you’re weak. That makes them hungry, and that’s when they come for you. So what do you do?’

‘Don’t let them know you’re weak.’

‘Or better yet, don’t be weak,’ said Torgaddon. ‘Be strong. I remember something the Warmaster said back in the day, you know, back before everything went to shit. He said that man has control of action alone, never the fruits of the action. Take control of your actions, Garvi. Remember that when things look their worst, you can only do what you think is right at the time.’

Loken heard the clatter of the airlocks on the far side of the dome.

‘I have to go now,’ said Torgaddon, holding out his hand again.

Loken looked at the proffered hand, but didn’t yet take it.

‘Are you really here or is this just my mind’s way of convincing me to do something I know I have to do?’

‘I don’t know,’ confessed Torgaddon. ‘Either explanation sounds unbelievable, but what do I know? I had my head cut off.’

‘Don’t joke, Tarik,’ said Loken. ‘Not now.’

‘I don’t know what to tell you, Garvi,’ said Torgaddon, suddenly serious, and the transformation was as unsettling as anything else Loken had experienced recently. ‘I don’t have a neat explanation all tied up with a bow. I feel real, but I think something terrible happened to me after I died.’

‘After you died?’ said Loken. ‘What could be worse than dying?’

‘I don’t know yet,’ said Torgaddon. ‘But I think you’re the only one who can undo it.’

Loken heard footsteps drawing near, the harsh ring of armoured boots telling him that another legionary was approaching. He looked back along the path, seeing a long, broad-shouldered shadow thrown out over the flagstones, and closed his eyes. He wanted this all to be a dream, but knew it was all too real and all too hideous to be so easily dismissed.

When he opened his eyes, Torgaddon was gone, if he had ever really existed.

Loken let out a breath that felt as if it had been caught in his chest for an eternity, as a warrior armoured in steeldust war-plate without Legion markings rounded the corner. Iacton Qruze, once known as the half-heard of the Luna Wolves, now one of Malcador’s Knights Errant, nodded in respect to Loken and held up a hand in greeting.

Loken returned the gesture and said, ‘Qruze, what brings you to the garden?’

‘You are summoned,’ said Qruze. ‘And this time you need to answer.’

‘Who summons me?’

‘Malcador,’ said Qruze, as though there could be no other summoner.

‘Then I will come,’ said Loken.

‘You will?’ said Qruze, apparently surprised by Loken’s answer.

‘Yes,’ said Loken, bending to lift a flattened stone from the waterfall’s edge. ‘Give me a moment.’

He hurled the stone out over the lake, smiling in satisfaction as it skipped and bounced over the water, before ricocheting back into the centre of the pool to land in the reflected image of the Solar System’s precious third planet.

Qruze watched the stone’s trajectory with a curious expression.

‘What was that all about?’ he asked at last.

‘Something Torgaddon and I did on the shores of a water garden’s lake one time,’ said Loken. ‘He could never master it, but I always managed to get stones further than anyone else.’

Qruze nodded, though Loken’s answer was plainly meaningless to him.

‘What’s that on your hand?’ asked the half-heard.

Loken looked down and smiled as he saw a bruise turning to yellow in the shape of a gibbous moon on the palm of his hand.

‘A reminder,’ said Loken.

‘A reminder of what?’

‘Something I still have to do,’ said Loken.

Garviel Loken, now in service to the Sigillite

An extract from Garro: Vow of Faith.

As he waited for the dawn glow to rise higher, the man turned in a slow circle and passed the time reading the history in the landscape around him. Some of it he gathered from his own instincts, more he took from flashes of mnemon-implants fed into his brain by the hypnogoges, long before he had come to Terra.

The forest of tall, mutated fir trees filled a valley that had once been a bay bordered by city sprawls now long-dead and lost. The iron-hard trunks, grey-green like ancient jade, ranged away in all directions beyond the clearing where he had landed the cargo lighter. He could see former islands that were now stubby mesas protruding from the valley floor, even pick out the distant shapes of old buildings swallowed by the tree line. But to the east, the clearest of the decrepit monuments to the dead city were the towers of a long-vanished highway bridge. Only the twisted remains of two narrow gates remained, rust-chewed and thousands of years old. Beyond them, in the time before the Fall of Night, there had been a great ocean; now, the strange forest petered out and became the endless desert of the Mendocine Plains.

The bleakness of that thought was somehow comforting. Entropy is eternal, it said. Whatever we do today, it will matter not in centuries to come. Forests anew will rise and engulf all deeds.

He turned and walked back to the lighter. The snow on the ground hissed beneath his footfalls as he came around to the drop ramp at the rear, open like a fallen drawbridge. Inside the flyer’s otherwise empty hold, a man in a maintenance worker’s oversuit looked up at his approach and pulled listlessly at the magnetic cuff tethering him to a support frame. The two of them were similarly dressed, alike in average height and nondescript aspect, but the chained man’s face was swollen and florid.

‘Haln,’ he began, his words emerging in puffs of vapour, ‘Look, comrade, this has gone far enough! I’m freezing my balls off–’

His real name was not Haln, but it was who he was today. He stepped in and punched the worker in the face three times to stop him talking. Then, while the man was dazed and reeling, Haln released the mag-cuff and used it to lead his captive out of the lighter. He chanced a look up into the cloudy sky. Not long now.

The worker tried to speak, but all that came out was a wet, breathy noise.

Perhaps he had thought they were friends. Perhaps the fiction that was Haln had been so good that the worker bought its reality without question. People usually did. Haln was a well-trained, highly accomplished liar.

He wanted to strike the worker again, but it was important that the man not bleed, not yet. With his free hand, Haln pulled a metallic spider from one of the deep pockets of his overcoat and clamped it around the worker’s throat. His captive whimpered and then cried out in pain as the neurodendrite probes that were the spider’s legs entered his flesh, and found their way through meat and bone to nerve clusters and brain tissue.

Haln released him, but not before giving the worker another item – an Imperial soldier’s battle knife. It was old, blackened by disuse and corrosion. There were stories in it, but they would not be heard today.

The worker accepted the blade, wide-eyed and confused. Wondering why he had been handed a weapon.

Haln didn’t give him time to think too long about it. He pulled back the sleeve of his coat to reveal a control panel with hologlyph keys, secured around his wrist. Haln placed the fingers of his other hand on the panel and slid them around, feeling for the right position. In synchrony, the worker cried out and began a sudden, spastic series of motions. The spider device accepted the signals from the control and made him a puppet. He staggered back and forth as Haln got a sense of the range of motion. He began to weep, and through coughing sobs, the worker begged for his life.

Haln ignored his slurred entreaties, walking him away into the middle of the large clearing where the chem-stained snow was still virgin. When he was satisfied, Haln looked again at the oncoming dawn and nodded once.

Highlighting two glyphs made the worker bring the old knife to his throat and draw it across. Manipulating other symbols forced his legs to work, walking him around in a perfect circle as blood jetted from the widening wound. Haln watched the spurts of crimson form jagged, steaming lines in the snowfall. Each wet red axis pointed away to the horizon.

Eventually, the cut killed the worker and he dropped, sprawled across the mark of his own making. Haln felt a change in the air, a grotesquely familiar acidity that was alien and uncanny. It was good, he decided.

He saw the object before he heard it. A hole melted through the low clouds and a flickering meteoric form fell from the sky. A heartbeat later, a supersonic scream came with it – although he knew no-one else beyond the valley would hear it, walled in and smothered as it was by the magicks the spilled blood provided.

The object slammed into the earth with enough shock force to toss Haln back ten yards, and rock the cargo lighter on its landing skids. When he rose to his feet, Haln saw that a shallow pit had been dug by the impact, revealing black dirt beneath the bloodstained snow. The worker’s corpse had been directly beneath the fall, the very point upon which it was targeted – and if any of the man now remained, it was only shreds and rags.

In the pit was a capsule not unlike those used to eject the bodies of the dead into stars for solar cremation. Hot and sizzling, it creaked and shuddered as something moved inside. Haln looked up again and saw the hole in the cloud sealing up once more. He allowed himself a moment to wonder where the pod had come from – dropped by a ship from orbit, dragged from the immaterium itself, conjured out of a dream? – and then forgot his own question. It wasn’t important. Only the mission mattered.

Heat seared him, even through his heavy gloves, but Haln found the seam of the capsule and pulled on it. A wash of thick air dense with human smells assaulted him, and fingers of fire-burned flesh emerged through the widening gap. Then presently a hand, an arm, a torso. A figure stepped onto Terran soil – a tall man with unkempt hair, a hawkish face and haunted, wild eyes – and glared at him.

‘It worked,’ he growled. ‘Each time, I think it will not. I shouldn’t. Should not doubt.’ The words he spoke were rough and scratchy. The new arrival’s tone made Haln imagine a feral animal taught to walk upright and speak like a person.

Haln gestured at the pod interior. ‘You need to kill your pathfinder, before it–’

The other man’s dark eyes flashed. ‘I know. I’ve done this before.’ He hesitated. ‘Haven’t I?’ He shook off his own question and reached into the capsule. With a wet tearing noise, he ripped a bulb of gelatinous, oily flesh from where it had been nestled in among the pod’s inner workings. It writhed and squealed, trying to squirm out of his grip.

Haln was going to offer the man another of his many knives with which to finish the task, but when he looked back the new arrival had a pistol in his fist. Haln had not seen him draw it, had not even seen a holster for the gun. Even the weapon itself seemed strange – he didn’t really see it, it was more like he saw the impression of it. Something murderous and accursed made of chromed parts moving with no mechanical logic; or was it assembled out of glassy crystal and ruby-red liquid? He had no time to really understand, because it fired and his vision went purple with the afterimage.

Even the proscribed mech-enhancements of Haln’s vision didn’t stop the retina burn, and he blinked furiously. After a moment, his sight returned and there was only grey ash where the pathfinder-thing had been. The pistol had vanished.

He said nothing of it. These things, these moments of not-understanding, they were not new to Haln. He kept himself above them by remembering – once again – the mission, the mission, always the mission.

‘Were you briefed?’ said the man. His manner shifted like the winds. Now he was cold and professional.

‘A basic summary. I am to provide operational support for the duration of your assignment,’ he replied. ‘My name is Haln, for the interim.’

‘How long have you served Horus?’

Haln hesitated, glancing around. Even here in the deep wilds, far from the nearest settlement, he was reluctant to speak the Warmaster’s name aloud. ‘Longer than I have been aware,’ he said, at length. A more honest answer to that question would be lengthy and complex.

That seemed to amuse the other man. ‘Truth in that,’ he allowed, and started for the cargo lighter. ‘There are several avenues to follow but only one target. You’ll help me locate it.’

Haln nodded and reached inside his coat for a melta grenade, priming the timer and radius so it would obliterate all trace of the pod and the sacrifice. ‘As you wish,’ he told the assassin.

Half a world away, a sky of artificial night made the wastes of Albia seem like a sketch in charcoal and slate. Miles above the ground, the aertropolis of Kolob cast a massive shadow as it floated on a ring of colossal antigravs, causing microclimate veils of hard, cold rain to race across the stony hillsides.

The warrior had been walking for the better part of a day. His Stormbird had climbed away and left him on a twisted crag somewhere in the northern sinks, just as ordered. He climbed down and started on a southerly path, his pace careful and the solid clanks and hisses of his power armour a steady metronome. He walked, waiting for the great emptiness of the landscape to clear his thoughts. It had not happened yet.

This place was home to him, or it would have been if that word held any true meaning for the legionary. His past was a gossamer thing, faint and ephemeral, so delicate that he wondered if looking too closely upon it would make it fade forever. The memories of the time before he took on oath and armour in service to the Imperium of Man were strange to him. In many ways, they were a fiction he had been told more than a chain of events he had actually experienced.

Had he ever really been the ragged youth that lurked in his deep recollection? The one that was sallow of face and always cold? If he reached for it, if he dug in and tried hard, he could pull some fragments back to the surface. Sensations, mostly. Pieces so small and dislocated that they hardly deserved to be thought of as memories. Warmth in the embrace of a parent. The sight of shooting stars crossing the sky. A lake of captured sunlight, as gold as coin.

Those events were centuries old. The outlines of the faces he saw there belonged to people long since dead and turned to dust, their voices lost to him. Wiped away by the bio-programming and hardwiring of his brain that made him a superlative warrior. Like all of his kind, the forgetting was required to reforge him into what he had become.

These grains of his old self were all that remained, trapped in the cracks of his newer nature, the one carved out of the body he was born in and built anew with implants, techno-organs and powerful genetic modifications. He carried a special, quiet apprehension that one day he would look for these grains and they would be gone. The legionary knew brothers like that, who had lost whatever had made them human.

He looked up into the sky, watching the orbital plate’s slow progress, thinking of those men. Some of them were like him, holding on to the threads of their better selves in silent desperation, but more – far too many more – had willingly opened their hands and let go of any ties to Terra, to the past, to who they had once been.

Once, he would not have had the words to describe these events, but ever since the insurrection, he did. He thought of his battle-brothers as having given up their souls, if there were such a thing.

The warrior halted at the edge of a crumbling ridge, surrounding a vast pit that resembled a volcanic caldera. There had been a city here long ago, assembled atop a network of tunnels and caverns, but wars had washed over it and torn it away. Remnants of the ancient caves were visible down there, laid bare by forces that had shredded mountains. He knew this place, the spectre of it trapped in one of the memory-pieces. Perhaps he had lived in the shanty-towns that clustered down along the walls of the pit, or ventured from one of the hive towers in the far distance. He did not know. The content of the memory was gone, only its empty vessel capable of bringing him to this place.

Another hard pulse of rain lashed over him, and he glimpsed his own flickering reflection in an elongated puddle. A hulking shape in ghost-grey wargear, face hidden behind a beaked, cold-eyed battle helm. A cuirass about his shoulders with golden detail, rendered dull and lifeless by the bleak sky. A great sword in the scabbard on his back, a master-crafted bolter clamped to his hip.

He reached up and removed the helmet, mag-locking it to a thigh plate, taking a breath of damp air laced with heavy pollutants. He met his own gaze on the water’s surface.

The Knight Errant Nathaniel Garro looked back at himself, measuring the scars that were the map of his war record. He felt old and empty, a sensation that had been banished from him for a long while but now returned in full effect. The last time he had experienced such a thing, it had been as the madness unfolded over Isstvan V. As he stood aboard the frigate Eisenstein and slowly came to the shattering conclusion that his legion had betrayed him. As the Warmaster Horus’ rebellion had been birthed before him, the very personal treachery of his brethren and his primarch Lord Mortarion hollowed him out.

Perhaps, if he had been without courage and honour, Garro might have faltered in that moment, might never have recovered from what he witnessed. But instead, he found a new kind of strength. Emboldened by the singular truth laid bare before him – that of his unswerving loyalty to Terra and the Emperor of Mankind – Garro defied the traitors and set upon a flight into danger, racing back to the Solar System with word of warning.

Had he been without focus, Garro’s future and that of the refugees he brought with him might have ended with that deed. But his loyalty found reward, of a sort. The Emperor’s right hand, the great psyker and Regent of Terra Malcador the Sigillite, took the reins of Garro’s purpose. The former Battle-Captain of the Death Guard became Agentia Primus of the Sigillite’s clandestine task force. He became a Knight Errant, legionless but charged with great deeds.

Or so he had believed. After years of working to Malcador’s byzantine orders, recruiting others like himself, chasing down Horus’ spies, secretly crisscrossing the stars beneath the shroud of a tormented galaxy, Garro’s certainty of purpose became clouded. More and more, he was coming to believe that fate had spared him at Isstvan for something larger than just the Sigillite’s enigmatic designs. Already he had openly challenged Malcador’s commands, in the Somnus Citadel on Luna and in the halls of an unfinished fortress on distant Titan. How long would it be before he spoke his doubts aloud and in the fullest? Garro could not hold to silence forever. It simply was not in his character.

His craggy face twisted in a scowl, annoyance flaring. He had been foolish to come here. Some sentimental part of his spirit hoped that walking these lands would take him to a calmer place, where he could quiet his uncertainties and find a measure of peace. But that was not happening, and he knew it would never come. He resented the lack of answers, the directionless unawareness that pushed and pulled at him whenever his thoughts should have been at rest. More than anything, he wanted to come to a place of tranquillity and in it, find understanding. Garro was a legionary, a soldier born to duty, but the one before him was not right. It was not enough.

Everyone in the galaxy had been changed by Horus’ sedition, if they knew it or not. Garro knew with great clarity how he had been altered. Something had broken free inside him as his Legion’s sworn oaths had blackened and disintegrated. He was more than just a weapon of war, to be directed at a target and told to fight or perish. A heavier mantle had fallen upon him, a champion’s duty.

Have faith, Nathaniel. You are of purpose.

The words echoed in his thoughts. The woman Keeler, she had opened his mind to that truth. She understood. Perhaps for Garro to understand too, he would need to find her again and–

On the wet breeze he sensed the stale odour of animals, and froze. Garro listened and picked out the footfalls of two quadrupeds, stalking him across the shale and mud. He turned his head and picked them out against the dark stone.

Lupenate forms, the pair of them. Predators evolved from the wolves that had once stalked the woodlands of this region, in the times before the trees had died off, never to return. Their large bodies were long and sinuous, their fur slick with secreted oils that sloughed off the toxic rains and made their thermal aspects harder to see. Arrow-shaped ears twitched and stiffened as they tracked Garro’s smallest movement, while narrow eyes fixed him with a gelid, hungry gaze.

Normally, lupenates stayed away from the edges of human-habited zones, preferring to prey on the odd unwary traveller caught out alone. That a hunting pair had come so close to the shanty towns in the pit could only mean their life cycle was being disrupted as well as everyone else’s on Terra. The global day-and-night preparations for Horus’ inevitable invasion trickled down to even the most insignificant of the planet’s creatures.

Garro had drawn his sword without being aware of it. The power blade Libertas, his stalwart war companion for a hundred years and a thousand conflicts, could slice through tank armour when fully charged. His lip curled. These animals were not worth that expenditure of energy.

‘Go!’ he barked at them, planting the sword in the ground with its hilt facing the sky. Garro took a menacing step toward the predators. ‘Be gone!’

But the lupenates were starving and agitated beyond rationality. They attacked, flashing forward in a glistening arc of motion. Both leapt at him, smelling his breath, claws and teeth aiming to gain purchase on the bare flesh of his face.

The legionary’s arm blurred and he snatched the closest of the creatures from the air at the top of its arc, grabbing it by the throat. The second he batted away with the back of his gauntlet – he saw it crash into the rocks with a furious yelp.

The lupenate in his grip spat venom at him, missing his face but spattering on his chest plate. The droplets sizzled where they landed, scorching the slate-coloured armour. Garro’s lips thinned and he threw the creature in the direction of the standing sword. His aim was true enough, and the blade so sharp even in its inactive state, that the force of the throw bifurcated the creature and sent its parts tumbling over the edge of the pit. He stalked across to the second, wounded animal and stamped down on its head, crushing its skull beneath his heavy ceramite boot before it could rise.

Grim-faced, Garro returned to recover Libertas. If he had believed in omens, the appearance of the lupenates would mean ill portent.

‘A wolf,’ said a careful voice, ‘attacking out of blind hate and savagery. That reminds me of someone.’

Garro withdrew his sword and replaced it in the scabbard, noting that the rain had suddenly stopped. ‘Horus is not a savage. Unless he needs to be.’

He turned and found Malcador studying the dead animal with mild disdain. Quite how the Sigillite was able to approach him without sound or signal, the legionary did not know. Garro had learned not to ask such questions, as there were never any answers that satisfied him.

‘Was it necessary to kill them?’ said the other man, rolling back the cloak that concealed his gaunt features. Pale, silver hair fell to his shoulders. ‘The beasts have as much right to be here as you.’

‘I gave them the chance to withdraw,’ said the warrior. ‘I would grant the same to any foe.’

‘Honourable in all things.’ Malcador gave a small shrug and looked away, dismissing the moment.

Is he actually here, Garro wondered? I could be perceiving some fragment of him projected by a psyker’s might… It was very possible that in all the times Garro had stood before the Sigillite, he had in fact never stood before him, at least not in the most literal sense. The Regent of Terra’s psionic power was said to be second only to that of the Emperor himself, and the Emperor…

Divine was not a word that Garro would have used, but there were few others that could encompass the power of the Master of Mankind. If the Emperor were not a god, then he was as near to it as had ever existed. The image of a golden icon, of a two-headed aquila dancing on the end of a chain, flitted through his thoughts and he pushed it away.

The Sigillite looked toward him, as if he could smell the memory just as the wolf-things had caught Garro’s scent. ‘You have not found what you are looking for, Nathaniel,’ he said. ‘This has become troubling to me.’

‘I perform my duties to your order,’ said the legionary.

Malcador smiled. ‘There’s more to it than that. Don’t deflect. I chose you to serve because of your honesty, your… simplicity. But as time passes, the clear view I have becomes more clouded.’ The smile faded. ‘Duty turns to burden. Obedience chafes and eventually becomes defiance. It was this way with the Luna Wolf.’ He nodded toward the dead lupenate. ‘I did not see it until it was too late. And so I am watchful for the same patterns now, closer to home.’

Garro stiffened. ‘After I tallied all the things I lost in order to prove my allegiance,’ he began, ‘my legion, my brotherhood… I told myself that the next man who dared to suggest I was disloyal would bleed for it.’

‘Ah, but your promise contains a fatal flaw,’ Malcador replied, ignoring the threat. ‘You begin from the assumption that loyalty is a fixed point, immutable once established…’ The Sigillite broke off, and turned to look eastward, his eyes narrowing as if attracted by something only he could perceive. After a moment he turned away and continued, speaking as if nothing had happened. ‘But it is a flag planted in sand, Nathaniel. It can and will drift under the action of outside forces you may never see, until you are challenged. You were loyal to Mortarion, until the moment you were not. You were loyal to the Warmaster, until you were not. You are loyal to me–’

‘I am loyal to the Emperor,’ Garro corrected him, ‘and on my life, that flag will never fall.’

‘I believe you,’ said the Sigillite. ‘But my point still stands. Your missions, the whole reason why I gave you the grey and my mark to carry…’ He gestured to Garro’s armour, where the small icon of a stylized letter ‘I’ was barely visible. ‘They have been obscured of late by other issues.’

Garro looked away. ‘You speak of what I glimpsed on Saturn’s moon.’

Malcador shook his head. ‘It began long before you ventured to places that are outside your purview.’ The Sigillite wandered to the edge of the pit and looked down, taking in the gloomy settlement far below. ‘You went to the Riga orbital plate at your own bidding. You have been casting out feelers in the time between your missions, looking for something. Someone.’

Garro became very still. Of course Malcador knows, he told himself. How could I have believed he would not see the pattern?

‘Yes,’ continued the Sigillite. ‘I am aware of the Lectitio Divinitatus and the believers who have read Lorgar’s book.’

‘Lord Aurelian? The Word Bearer…?’ Garro’s brow furrowed, unsure if he had heard Malcador correctly.

The Sigillite went on. ‘I know they think of our Emperor as a living deity, despite all his words to the contrary.’ He took a step back. ‘And I know of the woman, Euphrati Keeler. The mere remembrancer who is now revered as a living saint.’

The question slipped out of Garro’s mouth before he could stop himself from uttering it. ‘Where is she?’

Malcador gave a rueful smile. ‘Not everything is clear to me, Nathaniel. Even if that is the image I like to project. Some things…’ The smile became brittle. ‘Some places, even I cannot reach. As curious as that is.’

‘But if you know of them, why do you allow the gatherings to go on unchecked?’

‘There are so many, and more with each passing month.’ The Sigillite opened his arms to the sky. ‘But perhaps you have forgotten that we are embroiled in a war that threatens to consume the galaxy? There are many things of far greater import before me. They are not like the lodges that Horus used to suborn the legions. These believers are little more than groups of worried people drawing solace from the pages of a fanatic’s scribblings.’ He paused, thinking. ‘That book proves my earlier point, when I spoke of malleable loyalty. Lorgar Aurelian was so very faithful when he wrote it. And look at him now.’

Garro nodded. ‘I saw the XVII Legion before Ullanor, and then after Isstvan. Like day and night, they were – but still a commonality of mad zeal in each incarnation.’ He paused, marshalling his words. ‘But I am not a Word Bearer. I am not even a Death Guard any more. I am only the Emperor’s sword, and that I will remain until the day I die.’

‘I believe you,’ Malcador repeated. ‘But even the best of blades can become blunted and careworn if left untended. It is clear that you cannot function fully as my Agentia Primus while you remain distracted by other concerns.’ The Sigillite’s tone hardened, and Garro found himself unconsciously taking up a combat stance.

His war-implants flexed and came alive, as they would if he were about to engage a foe. The very real possibility that Malcador was going to end him sang through Garro’s nerves.

‘You are of no use to me if you are preoccupied. I need agents who are here, in the moment. I need weapons and tools, if I am to end the war before it blackens Terra’s skies.’

‘Speak plainly, then,’ Garro demanded. If the worst were to come, he would meet it head on; this was not the first time he had been ready for such an outcome.

Malcador sighed. ‘After much consideration, I have decided to grant you a leave of absence, of a sort.’ He gestured at the sky, the floating city still blotting out the weak sun above them. ‘Go and find your answers, Nathaniel. Wherever they may lie.’

It was the last thing Garro had expected from the Sigillite. Censure and reprimand, indeed… But not permission. ‘You would allow that?’

‘I spoke the words. I have granted it.’ Malcador eyed him. ‘But there are certain conditions. You will leave behind your wargear, your power armour, your weapons. And more importantly, you will go without the authority I have conferred upon you. In this, you will be only Nathaniel Garro, late of the Death Guard Legiones Astartes. Whatever you want, you will find it on your own.’

In the distance, Garro heard the sound of powerful engines on a fast approach. A dropship was coming in. The warrior reached for his sword and removed it, scabbard and all, from his armour. ‘I will not leave Libertas in the hands of another,’ he intoned. ‘All else, I agree to.’

‘And still you challenge me, even in this…’ Malcador folded his arms. ‘Very well. Keep the sword. Perhaps you will need it.’

A Thunderhawk in unadorned grey livery crested the far ridgeline and tore over the pit, slowing to a hover on jets of flame. It pivoted in place as the pilot looked for somewhere to set down. Garro had done nothing to summon the dropship, nor seen Malcador do likewise, and yet here it was.

‘They will take you where you want to go,’ said the Sigillite, his words carrying over the howl of the engines. Garro raised a hand to shield his face as the Thunderhawk settled on the wide crag, the down-draft blasting a spray of rainwater up and about him. ‘But do not tarry. Horus is coming and we must be ready. I will array every servant of the Emperor in preparation to resist him, and you are counted in that number. Am I clear?’

Garro nodded as the Thunderhawk’s thrusters fell to an idling growl. ‘Aye,’ he replied, turning back to look at the Sigillite. ‘It is–’

He stood alone on the ridge, as the rain began to fall once again.
