Let The Galaxy Burn

by Marc

  Castus shook his head slightly, but whether he was refuting the monster or agreeing with it Aescarion could not tell.

  ‘I can give you flesh that will not wither, only change and become home to a civilisation of pestilence. Do not follow the Imperium when it falls. With my help you can crash it beneath your heel, and become an Imperium yourself, my boy! I can show you what secrets this dark little universe contains. I can show you what it really means to exist in a world your Imperium is blind to.’

  Castus’s face was set but uncertainty flickered in his eyes like lightning. Aescarion could sense the insidious psychic worming that would even now be burrowing for his soul, but the Ultramarine was fighting it, trusting in the Emperor, refusing to bow before Parmenides’s strength.

  Castus tried to hold his hands up to his face and block out the sights and sounds that were trying to change him, but he was pinned by great chains of psychic energy, to the rock where he stood, utterly immobile, held wide open and totally vulnerable to the mental ambush. He tried to remember the years of training and conditioning in the temple of his fortress-monastery. He felt himself getting more and more desperate as he tried to recall all those words of steel that had been spoken to him by the Chaplains ever since he had first set foot in the Chapter’s aedificium. But they were all slipping away, as his mind was dissolved by Parmenides’s will.

  ‘Nnnoo… nnnnn…’ the Space Marine grimaced as he tried to form the words of defiance spinning in his mind.

  It was a new type of fear he felt now. He had known what it was like to feel the air shredded by bolter shells and laser fire, to anticipate, every second, the hot bloom of pain. And he had become used to it over the years, until it was not a real fear, but an understanding of the constant danger that accompanied a sacred duty to defend the Imperium.

  This was so different. Here, his body was not at stake. His mind was the prize, his spirit, his very soul. A Space Marine should never feel fear. But Castus felt it now, a fear of change to the part of him that had always remained the same, a part of him that was as sacred to him, in its own way, as the Imperium itself.

  ‘Domina, salve nos…’ he hissed through his teeth, grimacing, a thin trickle of blood running from one nostril.

  With a mental shrug, Parmenides cast a dark psychic mantle around Castus’s soul – a vast, terrifying emptiness, crushing, draining his spirit.

  Castus knew that if he had ever been strong enough to earn the armour of a Marine, he would have to be stronger now. ‘Imperator, in perpetuum, in omnipotens, in umbrae…’

  Aescarion tried to drag herself towards him but the very air was drenched with power and she, too, could barely move – she felt as if she were entombed in rock. Her ears buzzed with a low, savage laughter, and the abhorrent image before her was shot through with red flecks as her head pounded. ‘Never break!’ she yelled at the top of her voice, unsure if Castus could hear her. ‘Never break!’

  From between Parmenides’s eyes a shimmering psychic lance leapt out and transfixed Castus, laying him open, white arcs of energy leaping off his armour to the rock, lighting him up like a beacon in the darkness. Every fiendish trick the prince could muster was poured into Castus’s disintegrating soul.

  The crashing power smashed Castus to his knees with an involuntary scream of panic. Deep in his mind he scrabbled madly, grasping for the memories that were stripped from him and were incinerated by the force of Parmenides’s malice. Endless hours of battle blistered and died. The liturgies of the Ultramarines were blasted from his memory. And below even that, a past, a childhood, all were flayed away and burned. The threads of personality that had held him together melted in the psychic fire until all that was left were the most base instincts. The flame left him seared clean of all that had made him a Space Marine of the Emperor. Castus was reduced to an animal with no morals, no duty, no memory of the almighty Imperium that had borne him.

  And no faith.

  A tide of cold horror rose in Aescarion’s heart. Castus was limp, swaying where he knelt, his skin pale, blood running from his nose and ears. All his mental defences had been peeled away and the shrill scream that she could hear in her soul was the sound of Parmenides’s foul mind savaging the Marine’s spirit like a predator tearing apart its prey. Castus had been strong – but this foul Chaos filth had been stronger.

  ‘Do you join me? Do you belong, fleshy little ignorant man?’ the daemon prince’s voice rose amidst a screeching psychic crescendo. Answer! Answer! Do you embrace knowledge, and the plague, and the true path of humanity? Do you transcend your sad little species? Will you watch them fall beneath you, while you walk the stars?

  ‘Do you join me?’

  In a heartbeat the mental chains shattered, and Aescarion could move again. But she knew that this was the worst sign, because it meant that Castus had succumbed.

  ‘Yes!’ Castus yelled in a monstrous, throaty voice that was not his, throwing his arms wide apart as if offering himself to sacrifice. ‘Oh yes!’

  Parmenides laughed, and great walls of flesh pounded against the walls of the promontory, sending debris crashing around them. Aescarion was not going to die here. She was not going to join the Emperor, not just yet. The moment Castus gave himself to Chaos, he had given her something to avenge.

  She swung her power axe above her head and rushed at Castus, smashing the blade down amidst its howling blue power field. Castus blocked it with his forearm and his hand was severed in a waterfall of sparks. He looked back at her, not with the eyes of a man, but with the same black, filmy, liquid eyes of the Daemon prince, and smiled at her with Parmenides’s malevolent grin. His skin was scarred and pockmarked by the heat generated by the daemon prince’s invasion, his teeth were cracked and shattered. His body had been wracked and broken enough – but that was nothing compared to the mutilation of his soul.

  He did not bother to draw his combat knife or raise his gun. He simply drove the heel of his remaining hand into Aescarion’s breastbone and sent her sprawling across the rock with a strength not even a Space Marine should have.

  The Sororitas clung to the rock and saw the waves of filth rising towards her. She drew her stiletto combat knife from its sheath, but instead of rushing at her new nemesis and dying a good death, she drove it into the casing of her own jump pack. In two strokes the fuel inhibitor was sliced out, clear fuel spurting onto the stone.

  ‘Damnation tuum.’ she growled through clenched teeth. A heartbeat passed and her jump pack erupted into life. She rocketed into the air on a plume of flame as all the fuel was ignited at once. Her ears were filled with the roar of superheated air. The savage heat slammed against her and knocked her half-unconscious. The pack fused solid. The armour on her back began to melt and her hair caught fire.

  As she soared upwards and prayed that she would be immolated before falling back into the cavern, far below her the enfolding waves of Parmenides’s corrupt flesh covered Castus. In the darkness below Saafir, a new champion of Chaos was born.

  AS THEY WITHDREW from the burning ruins of the city of Saafir, the Imperial forces found Sister Aescarion, broken and shattered. Her fellow Sororitas had taken her from the rubble and transported her to the Order Hospitaller in the Ecclesiarchal Palace on Terra. In the dark majesty of that most ancient of worlds, the priests and apothecaries grafted new skin on to her back and furnished her with a new suit of black power armour and white dalmatic from her Order’s vaults. They gave her back her hair, so her red-brown ponytail hung between her shoulder blades as if it had never been seared away. But she still had her scars, tiny scorches around her hairline, like hundreds of toothmarks.

  When she gained consciousness in one of the wards of the Order of the Cleansing Water, they told her a story she already knew. They told her how the Ultramarines and the Sisters of the Ebon Chalice had been selected to support the Imperial Guard in assaulting and recovering the heretic city of Saafir. About how the cultists they found there were cut down in hails of bolter fire until suddenly a
tide of foulness had bubbled up from below the streets, carrying daemons of the Plague God with it: grinning, one-eyed abominations carrying swords of venomous black metal, tank-sized beasts that killed with a touch of their bestial tentacles, and millions of tiny, pestilent abominations, which giggled insanities as they swarmed into armoured vehicles and even between the joints of power armour. Aescarion was familiar with the way the Marines and Sisters had been forced back, selling every inch of ground for a few drops of daemons’ blood, but were finally forced to abandon the city to its fate as the forces of Nurgle grew overwhelming in number and ferocity.

  Aescarion answered with a tale of her own, telling how her Seraphim squad had been cut down in mid-air by the poisoned blades of the Plaguebearers and vast thunderheads of fat, purple flies. How she and Castus had found themselves alone in the carnage, facing an assault that oozed straight up from hell. And finally, how the streets had given way beneath them and delivered them into the underground chamber containing the vilest creature imaginable.

  She told them of Castus’s fall from the Emperor’s light, and they hung their heads in shame.

  AT ONCE THE Ultramarine armour had been fused to his muscular frame. The blue surface and white Chapter symbol blistered off and the plasteel plates transformed into a living metal which thickened and split, drawing itself into biological curves which oozed dark fluid at the joints. Sometimes he could catch scenes reflected in the dull surface – a darkness descending from the skies, the tear that splits reality in two, Nurgle himself emerging laughing from the shattered remains of the galaxy.

  The Plaguebearers that attended to him brought him a morningstar. The haft was cut from the leg bone of some monstrous beast, and the head had been hacked from a stone so black it drank hungrily at the light, and a dark halo played about it constantly. To hold it, he had a new hand made of overlapping plates of dark purple crystal, which flexed and gripped with a cold, alien strength.

  On his other arm was a shield as tall as he was, bound in layers of human skin. The varying shades had been wrought into the triple-orbed symbol of Nurgle, and it was drenched in such sorcerous elixirs that it could turn the blows of gods.

  The helm they placed on his head had a single eye-slit through which he seemed to see better than with any auto-senses. This was just as well because his implants had soon fled him, wriggling out of his new flesh like metallic maggots.

  The Plaguebearers looked upon him with approval in their single glowing eyes, their ever-grinning mouths stretching wider. Castus held his new arms high above him and screamed a never-ending scream, so that even Nurgle on his throne of decay would hear him in the warp and perhaps smile a little at the dedication of his new servant.

  THE CULTISTS HAD no time to react as the circle of angels dropped around them from the ceiling of the space hulk’s dormant engine room, stitching vermilion threads through their bodies with twin bolt pistols. The cultists were naked to the waist, their bodies and faces daubed with crude symbols in woad of strange colours, their skin white and tarnished by the touch of decay, their eyes black and empty. But armour would have helped them little here, as the concentrated fire cut them down before they could hope to fight back.

  The graceful black Sororitas armour flashed in the light of Sister Johannes’s hand flamer as it spat a gout of blue-hot flame into the centre of the circle, carving a charred canyon through the torso of one and setting two others alight. The cultists howled, spinning like madmen as the blazing chemical adhering to their skin tore its way into their muscles and organs, until their unholy life was burned from them. They slumped to the ground, skeletons of smouldering ash.

  Aescarion’s axe-head sliced down into one cultist’s shoulder, severing the left side of his body to leave him staggering, almost comically lopsided as his organs spilled out onto the floor. Canoness Tasmander had wanted to present Aescarion with an ancient power sword, in recognition of her famous strength of faith beneath Saafir. But she had refused it: it was too elegant a weapon with which to despatch heretics – they should be slaughtered like animals and pounded into the very earth. That had been a long time ago now – now she was in command of a new Seraphim squad who had become her sisters – but the axe remained beside her just the same. And it was that axe which descended upon the hulk’s ill-prepared defenders, lopping off limbs and splitting carcasses like a butcher’s cleaver.

  A spattering of lasgun fire broke against the walls; one impacted on Aescarion’s greave. ‘By sections!’ she yelled and the Seraphim broke their killing circle, their jump packs hauling them into the air from where they swooped down onto the remaining cultists. The last heretics died so quickly they didn’t even have time to scream.

  The hulk seemed to have been built by giants. In itself it was the size of a hive city, and everything inside it was immense. In the engine room, ornate turbines as big as city blocks loomed above, too high for their crenellated tops to be visible, and immense pistons bridged the shadows. Everywhere had been daubed with the primitive slogans and symbols of the Plague God, and a reek of death and despair hung in the fetid air. This was a dark, terrible place. But for Aescarion, that was good – because it meant she must be close.

  The majority of the hulk had been deserted, and they had spent days picking off the few lifeforms on the scanner. This squad was now as familiar to her, after years of missions, as the Sisters she had lost on Saafir, and they were good, even for the chosen Seraphim.

  She was good, too, she knew, for she had learned a great deal of warfare since Saafir. There was a new purpose to her, beyond the service of the Ecclesiarchy. It had driven her to pursue Castus across the stars for almost longer than she could recall, and now her nerves were on fire, because she had found him.

  ‘How far now, Ismene?’ she asked.

  ‘Not far, my sister.’ Ismene said, the ancient scanning device’s pale green glow lighting her face. It showed that she was no longer a young maiden, fresh from the Schola Progenium – they had been hunting darkness for a long time now together. Strong, but not young.

  ‘Then follow.’ Aescarion strode through the darkness towards the corridor leading to the ship’s control centres.

  Sister Johannes looked up from examining the smoking corpses she had created. While Aescarion’s scars were unobtrusive, Johannes’s formed a web of chewed-up skin spread across her face. They were a relic of a past mission to a hive city and an altercation with a chainsword, and made her look like a savage. ‘Forgive me, Sister Superior, but how can you be sure it is him?’

  ‘I do not know him well.’ Aescarion replied, fixing her Seraphim with a cool gaze, ‘but I know him well enough. Follow.’

  The rest of the squad checked their ammunition and marched into the corridor. The walls were streaked with foulness, blood and viscera. Scraps of skin clung to the edges of the metal. The passage grew narrower and narrower, until finally they came to a bulkhead that blocked their way. The symbol of Nurgle was smeared on it, in blood both human and otherwise.

  ‘Grenades.’ Aescarion commanded, and hacked the door off its hinges.

  The Sisters threw their krak grenades into the space beyond. Aescarion’s auto-senses snapped her pupils shut in front of the sudden light.

  She was not afraid. She just wanted to see if he really was here, at last.

  The flare died down and the captain’s suite was revealed in tatters, its elaborate hangings and fine furnishings first defiled by the presence of corruption, then scoured clean by the armour-piercing shrapnel. The intricate murals on the ceiling could just be made out under the filth and scorching, and at the far end a huge, ornate window looked out into space, a black velvet tapestry studded with a billion points of light.

  The quartet of blasts had not killed him. Aescarion had not expected them to.

  He stood in the flickering wreckage, a standing stone of a warrior, his bright armour twisted beyond recognition and corroded gunmetal grey. One hand was composed of dark amethyst cut into a thousand facets, catchin
g the starlight in sinister forms. The eye-slit of his helmet pulsed with a sickly yellow glow, and his hands bore a full bodyshield and a monstrous ball and chain. He swung the morningstar slowly above his head, thrumming in the air and leaving an eldritch trail of reeking black fire behind it.

  Aescarion felt a cold shadow of the horror she had felt many years ago. But that was not all. There was some pride, sinner that she was, that she had managed to track him down even though he had been sowing decay across the galaxy since he had first been turned. And most of all she felt that most wonderful thing: the blank hate of the Sisters of Battle, the refusal to accept that such an enemy could exist, the absolute certainty that to kill him would be right. Aescarion unholstered her bolt pistol and levelled it at Castus’s face.

  ‘Damnatio tuum.’ she cried, and the Sisters fired in unison.

  Castus took most of the shots on his shield, the rest going wide or ricocheting from his armour. Two penetrated and raised sprays of blood, but he stood firm. The champion of Nurgle swung his morningstar once and drove it downwards, shattering the face of the nearest Seraphim in a shower of bone. The next he drove to the ground with his shield. Instinctively she flipped her jump pack switch and hurtled away from him, hitting the far wall and tearing like a fly against glass.

  Aescarion yelled with rage and dropped the pistol, taking her axe in both hands and rushing at her nemesis. Castus turned to catch her on his great shield, flipping her over with her own momentum. She hit the ground hard and felt something break.

  A cataract of flame caught the champion off balance. Johannes’s mutilated face was twisted into a grimace – she made ready to sell her life dearly, drawing the hulking warrior away from her Sister Superior. Castus covered his face from the heat and swung the morningstar into her midriff, flinging her across the room, still trailing flames. A staccato burst of pistol fire from Ismene lasted only as long as it took Castus to behead her with a swipe of his shield.
