The First Heretic Read online

  ‘I am cognizant of the details, Sergeant Dagotal.’

  Xi-Nu 73 was a stick-thin being, human only in the loosest sense. His red robe flapped in the heated wind, revealing an augmented body of lustreless iron bound together by industrial cabling. His arms, which he now raised in order to lower his hood, were a skeleton’s limbs constructed from contoured armour plating, ending in bronze hands with too many fingers. His face, such as it was, appeared from the lowered hood as a mess of thin wires and a noisy respiration mask, with no other discernible features beyond the green eye lenses that formed a triangle’s cardinal points.

  Xi-Nu 73 had been human once – almost a century ago in the short, fragile two decades after his birth. Like all of the Mechanicum of Mars, he’d had to endure those early years living in a shell of warm meat and wet blood, until he gained the skill to purify himself.

  He’d improved himself a great deal since then.

  The tech-priest stood by the Mechanicum lander’s cargo ramp, overseeing the ungainly march of several towering figures. Each one was clad in dense armour plating painted in chipped coats of crimson. They stood almost five metres tall, their mechanical joints not even attempting to mimic human motion. The first two down the clanging ramp were gangly Crusaders, their long bladed arms swinging as their shoulders rocked side to side in awkward motion. Circuitry, thick and crude, was etched along the arm-swords’ edges, linking the blades to power generators in the robots’ bodies.

  –Sanguine– said the first, vocalising in tinny machine tones, –standing ready–.

  –Alizarin– the second intoned, –standing ready–.

  The third figure to stomp down the ramp was twice the width of the first two, bulky where the Crusaders were gangly, great fists of riveted metal fused to form siege hammers. Even more than its kin, it reeked of greased machine parts and the earthy scent of lubricating oils. The Cataphract-class machine was hunched, made dense by sloping armour, and moved with even less claim to grace than the others.

  –Vermillion– it droned as it clanked in line with the Crusaders, –standing ready–.

  Xi-Nu 73 turned his eye lenses to regard the last machine emerging from the lander’s hold. This one seemed a compromise between its construct-kin, almost human in its posture and gait, armoured with thick plating and bearing weapons for arms. A third cannon rose from its shoulder, with ammunition belts trailing down its back, dreadlocks of bronze shells rattling with each step. Dagotal knew each of Xi-Nu’s wards, familiar with them from twelve years of sharing battlefields. This last was a Conqueror, and the primus unit of the group. It wore a Legion banner over its shoulder, and its armour plating was etched with Colchisian runes.

  Several of the Word Bearers saluted this last robotic warrior. It didn’t acknowledge them.

  –Incarnadine– the Conqueror declared in a voice devoid of personality, –standing ready–.

  Xi-Nu 73 turned to the gathered Word Bearers, his eyes refocusing yet again. ‘Greetings, sergeant. Ninth Maniple of the Carthage Cohort, awaiting orders.’

  Argel Tal hit the ground running, the boosters on his back cycling down as he ran. Both blades were sheathed; in his fists, a richly-inscribed bolter bucked with each fired shell. He took refuge with several of his warriors in the lowest level of a glass tower, shooting out of the stained glass windows. Whatever patterns the coloured glass once held were gone, smashed through by Word Bearers needing clear lines of fire.

  The Obsidian in the street outside dwarfed them all, liberally blasting the road with streams of electrical force from its featureless face. Argel Tal reloaded, and as he slammed a fresh magazine home, he had a momentary glance of a glass shard by his boot – a fragment of the stained glass window showing a figure in golden armour.

  Dagotal Squad was running interference, weaving between the artificial’s insect-legs, veering and jinking to avoid its lethal arcs of fire. Bolter shells hammered into its joints from where Torgal’s men took what cover they could find, but their efforts were little more than an irritant.

  ‘Xi-Nu 73,’ Argel Tal voxed. ‘We’re in position. Make this fast.’

  ‘Acknowledged, Seventh Captain.’

  They came from behind the construct, emerging from a subsidiary road. Sanguine and Alizarin stalked forward first with all the grace of stumbling beggars, their movements a stark contrast to the liquid grace of the enemy machine. Lascannon fire streamed from the shoulder mounts of both Crusaders, carving searing scars into the Obsidian’s skin, the sludge-gleam of melted glass bright against the black. Their arm-blades came up on clanking, motorised hinge joints, slicing down to chop at the construct’s legs.

  Recognising this new threat, the Obsidian span to face the Mechanicum war machines. It turned into a barrage of gunfire, shoulder-mounted heavy bolters punching shards from the construct’s face and torso with a torrent of explosive shells. Incarnadine, regal in form compared to its brothers, tracked every movement made by the enemy machine. It didn’t cease fire, even for a second. Nor did a single shot go wide.

  The Obsidian’s storm-stream wasted itself, blasting up at the sky as the Mechanicum robotics knocked it off-balance.

  The Cataphract-class Vermillion, as bulky as an Astartes Dreadnought, was an altogether more ponderous engine. Stocky and lumbering, it closed the distance as the Obsidian sought to right itself on its four remaining legs. Siege hammers swung in, meeting alien glass with a thunderclap’s refrain. Four legs became three – the glass machine crashed to the knees it had left.

  ‘Finish it,’ said Argel Tal. His jump pack burned again, groaning as the engines drew breath.

  ‘By your word,’ came the vox-replies.

  The swords came free in smooth pulls, and Argel Tal let a short burst of thrust carry him skyward. Even prone, the Obsidian offered no purchase. As the Word Bearers came down in its back, most elected to hover, burning their jump jets rather than standing upon the thing’s body. Swords clashed and carved, but only Argel Tal’s empowered blades inflicted significant damage, sending shards of dark glass flying with each hack.

  Even as it died, the Obsidian dragged itself across the street, a grasping hand reaching for the closest true threat. Incarnadine stepped back, autocannons laying into the outstretched hand, shearing fingers from the fist. Behind the Imperial war machine, Xi-Nu watched with unwavering attention, occasionally adjusting dials on his chestplate for reasons none of the Word Bearers had ever discerned, despite a decade of fighting by his side.

  When the Obsidian lay still at last, Argel Tal and Dagotal came over to the tech-priest. The downed enemy construct had a shapeless resemblance to a melting ice statue, its body ruined by a thousand bullet impacts, blade cuts and lascannon beams. Both Word Bearers crunched closer on the glass shards lining the road.

  ‘Greetings, captain,’ said Xi-Nu 73. ‘Ninth Maniple of the Carthage Cohort, awaiting orders.’

  Cyrene paused Argel Tal’s retelling with a hand on his forearm.

  ‘You used artificials yourself?’

  He’d been expecting this. ‘The Legio Cybernetica is a treasured facet of the Mechanicum. The Great Crusade leans heaviest on the Legio Titanicus for their war engines, but Cybernetica plays its role among the noblest Astartes Legions. Their artificials are robotic shells housing machine-spirits. Cybernetica tech-priests engineer organic-synthetic minds from biological components.’

  Cyrene reached for the glass of water on her bedside table. Her fingers slid across the metal surface, bumping the glass gently before she got a grip. When she drank, it was in little swallows, and she seemed in no rush to speak again.

  ‘You don’t see the difference,’ Argel Tal said, not quite asking.

  She lowered the glass, facing him without seeing him. ‘Is there a difference?’

  ‘Do not ask that question to Xi-Nu 73, should your paths ever cross. He’d be insulted enough to kill you, and I would be vexed enough to kill him in return. Suffice to say, the difference is in the mind. Organic intelligence, even synt
hetic in nature, is still tied to the perfection of humanity. Artificial intelligence is not. That’s a lesson many cultures only learn when their machine slaves rise up against them, as the Obsidians would have done one day, to the people of Forty-Seven Sixteen.’

  ‘You always say we are perfect. Humans, I mean.’

  ‘So it is written in the Word.’

  ‘But the Word changes over time. Xaphen tells me it’s changing even now. Are humans really perfect?’

  ‘We‘re conquering the galaxy, aren’t we? The evidence of our purity and manifest destiny is clear.’

  ‘Other races conquered it all before we did.’ She took another sip of the room-temperature water. ‘Perhaps others will conquer it after we do something wrong.’ Then she smiled, brushing a lock of hair back from her face. ‘You are so certain in everything you do. I envy you for that.’

  ‘Were you not sure of your own life’s path back in Monarchia?’

  She tilted her head, and he read a faint tension in her body language – the slight curl of her bare toes, the fingers gently clutching her grey robe. ‘I don’t wish to speak of that,’ she said. ‘I just find it curious that you have no regrets. No doubts.’

  The Astartes wasn’t sure how to answer. ‘It’s not confidence. It’s... duty. I live by the Word. What is written must come to be, else all will come to nothing.’

  ‘That sounds like a great sacrifice to me. Fate shaped you into a weapon.’ Cyrene’s smile was tinged with an expression somewhere between amusement and melancholy. ‘The Speakers would say such things in their dawn prayers across the perfect city. “Walk the one true way, for all other paths lead to destruction”.’

  ‘That‘s from the Word,’ said Argel Tal. ‘Part of the primarch’s wisdom we left to guide your people.’

  She waved a hand, batting aside his devotion to every detail. ‘I know, I know. Will you tell me the rest of the story? I want to know more of the city. Did the primarch fight with you?’

  The captain took a breath. The girl’s mind moved with fleeting touches between subjects.

  ‘No. But we saw him at dawn. Before we reached his side, we crossed paths with Aquillon.’

  ‘Tell me what happened,’ said Cyrene. She lay down on her bed, making a pillow of her joined hands. For what use they were, her eyes remained open. ‘I’m not sleeping. Please, go on. Who is Aquillon?’

  ‘His title is Occuli Imperator,’ Argel Tal replied. ‘The Emperor’s Eyes. We encountered him as the sun set, while most of the city burned.’

  At the Heart of a Fallen City

  As dusk fell over the city’s remains, Argel Tal stood in battered armour, watching the amber disc sink beneath the horizon. It was a beautiful sunset, putting him in mind of Colchis, of home, of the world he’d not seen in almost seven decades. To his recollection, which bordered on eidetic, Argel Tal had seen the sun set on twenty-nine worlds. This was the thirtieth, and as lovely as the first.

  The sky darkened in shades of blue and violet, heralding the coming night.

  ‘Chaplain,’ he said, ‘to me.’

  Xaphen left the regrouping Word Bearers, walking to the captain at the end of the street.

  ‘Brother,’ Xaphen greeted him. Without his helm, the Chaplain watched the setting sun with naked eyes. ‘What do you need?’

  Argel Tal nodded to the fading heavens. ‘Reminds me of home.’

  He heard the faint growl of armour joints as Xaphen moved. A shrug, perhaps.

  ‘Where is Torgal and the Assault Squad?’

  ‘Scouting along the spire-tops,’ the captain said. ‘I will be glad when this world is at compliance, Xaphen. Despite the need to see battle, this is a hollow war.’

  ‘As you say, brother. What do you need?’ the Chaplain repeated.

  Argel Tal refused eye contact.

  ‘Answers,’ he said, ‘before we return to orbit. The primarch remains away from us for a month, and the Legion’s warrior-priests gather in silence. What happens at the gatherings of those who wear the Black?’

  Xaphen snorted, already turning away. ‘Now is hardly the time. We’ve a world to bring to compliance.’

  ‘Do not walk away from me, Chaplain.’

  Their gazes met – the captain’s slanted eye lenses locked to the Chaplain’s narrowed eyes. ‘What is it?’ asked Xaphen. ‘What has you so unfocused?’ His tone mellowed, conciliatory despite its sternness. Argel Tal knew the voice well. It was how Xaphen spoke when warriors brought their doubts to him. Without knowing why, Argel Tal found it tainting his temper.

  The captain aimed his sword down the street, where two squads were tending to their wounded. Much of the roadway was taken up by the corpse of another Obsidian, and Dagotal’s bikes undergoing battlefield repair by Xi-Nu 73.

  ‘We are all blind,’ said the captain, ‘except you. We are fighting as ordered, exterminating a heretic culture. And Aurelian was right – it is a purge of the past, and good for the blood. The Legion needed to stand in victory after gathering to commemorate failure. But after a month of silence since the perfect city’s grave, we are still blind.’

  ‘What would you have me say?’ Xaphen approached again, his gauntlet lifted as calculating indecision played across his features. He withdrew the hand, sensing if he rested it on Argel Tal’s shoulder, it would aggravate the captain, not remind him of kinship.

  ‘I would have you answer the question and enlighten your brothers, as your duty demands.’

  Xaphen exhaled, and his patience left with his breath. ‘The gatherings of those in Black are inviolate and sacrosanct. None of us may speak of what transpires. You know this, yet still you ask? What of tradition, brother?’

  Argel Tal lowered the sword. ‘What tradition?’ he laughed. ‘What of a Legion kneeling in the dust, and our primarch offering us nothing but silence for a month? The rest of us need answers, Xaphen. I need answers.’

  ‘By your word, captain. But all I may say are words I’ve spoken before. We look to the Word, and seek a new path. The Legion is lost, and we seek the answers to guide it again. Do you begrudge us that? Should we linger, lost in the void, cast from the Emperor’s light?’

  Argel Tal felt acidic saliva stinging under his tongue. ‘Meanwhile, the Legion waits and wages war, equally blind in both states. Do the Chaplains have the answers they sought?’

  ‘Yes, brother. We believe so.’

  ‘And when did you plan to share these truths with us?’

  Xaphen drew his crozius, clutching it in both hands as he turned back to the gathered squads. ‘Why do you think we came here? Purely to end these miserable blasphemers? To wipe this pathetic empire of one lonely world from the face of history?’

  ‘If you find my insight lacking,’ the captain spoke through clenched teeth, ‘then enlighten me.’

  ‘Peace, my brother. Lorgar knows the value of symbolism, and the purity of purpose. We followed a false path that ended in a city of ashes. In another city of ashes, we will take the first steps on the true path. He will show us the way, and we will perform the Rite of Remembrance as it should be performed, with honour and sincerity. Not collared by the Emperor and abused like disloyal hounds.’

  This was, and wasn’t, a surprise to Argel Tal. It didn’t take a prophet to predict the primarch would speak after this compliance, but to have it framed as some first step on a new odyssey was both captivating and unnerving.

  ‘I lament that the Chaplain brotherhood kept this from us, but I thank you for speaking at last.’

  ‘There was little to tell before the primarch’s return today. It‘s no secret, in truth.’ Warmth returned to Xaphen’s craggy face as he smiled. ‘I expect word is filtering through the Legion even now. Aurelian will meet us in the heart of the city, once we’ve extinguished the last of this world’s unholy life. And this time, when the Legion kneels in the dust of a dead city, it will be because that city died in righteous flame.’


  The vox chose that moment to crackle back to life.

  ‘Sir? Sir?’

  ‘This is Argel Tal. Speak, Torgal.’

  ‘Captain, I apologise for another unpleasant surprise, but you won’t believe what I’m looking at.’

  Argel Tal swore under his breath, the clipped Colchisian syllables not carrying over the vox. He was growing tired of hearing those words on this world.

  The five warriors killed in silence, their glaives spinning with the force and speed of turbine rotors, lashing through limbs and torsos with the ease of knives through mist. At last, with the Legion breaching deep into the city, Imperial forces encountered human resistance. The army of constructs seemed defeated, reduced to scattered pockets. It fell to the militia and the civilian population to die fighting, taking to the streets armed with weapons that would prove useless, seeking to squander their lives rather than surrender them.

  Small-arms fire clattered from the warriors’ gold-wrought armour as they battled through the crowded street. The militia squads against them carried rifles that spat a solid shot not far removed from the smallest-calibre bolter shells. The culture’s ancestral connection to humanity’s pre-Imperial era was proven beyond dispute – and yet they were damned by their deviance.

  Despite their worthless weaponry, they stood their ground in cover or arrayed in firing lines until they were overwhelmed. Their planet was finished and their final city was aflame. With nowhere to run, most simply didn’t try. They died in their uniforms, which were the same grey as the city’s architecture. Faceplates of clear glass shattered under stabbing blades as the spear-bearing warriors scythed into another phalanx of human militia.

  The Custodes leader was obvious as he led the advance, his conic helm crested with a plume of red horsehair. In his hands, an immense two-handed sword span in blurring arcs, rising and falling, stabbing and carving. People tumbled away from him, some of them screaming, all of them falling to pieces in his wake. He killed and killed and killed, never missing a lethal strike, never slowing in his advance. Beneath his feet, the road ran red – the beginnings of a sick river, sourced by blood.
