Perhaps the Warmaster’s words had been intended as a balm for Perturabo’s tortured soul, but so dark a benediction had only driven him deeper into abyssal guilt. What might once have appeared as the basest of treacheries now seemed like the only logical course, and Perturabo had reaffirmed his oaths of loyalty to Horus.
No one knew what else had passed between these two demigods, but when the Iron Warriors had set foot on Isstvan V, it was with a murderous rage that could only be quenched in the blood of those they had once called brothers.
Berossus floated through the chaos of the massacre on the black sand, the savage joy he had taken in the shock of betrayal on the faces of every midnight-skinned Salamander and ivory-faced Raven Guard. Of the Iron Hands, he had seen little, for the Phoenician’s warriors were making sport of them, their debaucheries unseemly but effective.
He remembered killing a Salamanders captain with a close-range blast of his meltagun, relishing the irony of ending his life with fire. The warrior’s helmet had run molten from his face, leaving the skull exposed and as black as the skin that sloughed from the bone like hot oil. Even as he died, the warrior had cursed him in a bubbling series of liquid gasps that made no sense. He’d left the Salamander to choke on his own liquidised flesh, dismissing the curse as a vestigial remnant of his upbringing on a feral world of savage-born reptile hunters.
Drifting in this timeless limbo of pain and isolation, the Salamander’s molten visage returned to haunt his nightmares, a leering skull with coal-red eyes that bored into him with accusatory force. The screaming skull never left him, braying meaningless static and pressing close to his awareness, forcing him to relive the agonies it had known in its final moments.
Behind the skull was another face, a bitter granite-carved mask with cold, blue-steel eyes and a voice before which all else was white noise. It commanded the blackened bone of the Salamander, telling it that Berossus would not die as everything else had died. Even in his disembodied state, Berossus knew these were commands that could not be ignored.
The Salamander’s skull brought life, but most of all it brought pain, its red eyes reducing him to scraps with chanted evocations. Berossus tried to retreat from its calls, but it had strength beyond what was left to him and a hunger for his suffering.
He felt a jolt of screaming agony course around his body, a shuddering paroxysm of electric rebirth, and even as dimensions of space and form coalesced around him he loosed a shuddering roar as he felt the immense power in his limbs.
The world of darkness in which he had existed for what felt like an eternity was washed away in a cascade of painful colours that made him want to close his eyes. The colours bled away, but not his rage, and he shook as he saw the Salamander’s red-eyed skull before him.
Except it wasn’t a Salamander and it wasn’t a skull.
The Techmarine’s eye lenses were whirring optics, enlarged orbs of clicking armatures and rotating ruby lenses mounted on a bulbous apparatus of bronze and silver. His helm was blackened iron and a trio of hissing pneumatics crouched at his shoulders like obedient stingers of metal and dripping fluids.
‘Who are you?’ he said, his voice a grating bark that sounded nothing like he remembered.
‘I am Galian Carron, and you are in my war-forge,’ said the Tech-marine, who stepped back with a wary flinch as Berossus shook in the unbreakable fetters that bound him. Carron was looking up at him, for he was taller by far than the Techmarine. Grey-fleshed servitors and heavy lifter gear stood around him, some before him, some behind him – though how he could see them was, at present, a mystery. A host of robed acolytes bearing oiled platters, upon which were a variety of cogs, gear and machine parts knelt behind Carron; the Techmarine’s devotees.
No, not Carron’s devotees.
His.
‘Why am I here?’ asked Berossus, feeling unfamiliar walls of cold iron pressing in around him, a life-preserving womb and a sarcophagus all in one. Claustrophobic madness extended a tendril into his mind, and found itself welcome.
‘You are here because the Lord of Iron willed it so,’ said Carron.
‘You lie,’ said Berossus, desperate and yet hopeful. ‘He killed me.’
‘No, he has transformed you.’
‘I don’t understand,’ said Berossus.
‘By his own hand he has remade you in his image,’ said Carron as one of his wheezing pneumatics reached up and took hold of a rubberised control box. At the press of a button, the fetters binding Berossus’s limbs unclamped with a mechanised sound of grinding metal. His legs, twin columns of iron, steel and fibre-bundle muscles were his again to command, and he took a ponderous step forwards, knowing, with his first, that there would be no release from this entombment in an iron coffin.
The sound of his splay-clawed footfalls rang from the floor plates of the war-forge with a boom of metal on metal. His arms, a monumental hammer and a heavy-barrelled rotor cannon spun in time with his thoughts.
‘I am alive?’ asked Berossus, not yet ready to believe it.
‘Better,’ said Carron. ‘You are a Dreadnought.’
Holding the citadel had never been a possibility, Captain Felix Cassander of the Imperial Fists knew, but that had never been the point. The Iron Warriors were the enemy, and though his thoughts still balked at the thought of the Legiones Astartes turning upon one another, the enemy had to be fought.
Yes, the citadel must eventually fall, but Cassander did not hold with the notion of the unwinnable fight, the noble last stand or poetic notions of self-sacrifice. There was always a way to win or at least a way to cheat death, but even he had to admit that there was only the faintest hope of them surviving much longer.
Cassander was not a man to whom pessimism came easily, but it was taking considerable effort of will to keep its dark touch from infecting his thoughts.
When the Iron Warriors finally overcame the citadel’s ancient defences and broke open its walls they would run amok. They would slaughter his warriors, the heroic men and women of this world that had chosen to stand with them, and the refugees from the murder fields below. Fifty-two Imperial Fists and thirteen thousand men, women and children were crammed within the citadel’s walls.
When the end came, their deaths would not be quick and they would not be painless, but there was no talk of surrender or terms, no seditious mutterings to erode morale and no thought other than resisting these bastard invaders.
The Iron Warriors… our brothers…
No history told who had built this marvel atop the mountain, though the engineers and artisans who had raised its living walls must surely have been the greatest minds of their age. Wrought from stone and rock unknown to this world and laced with technologies whose secrets not even the Mechanicum could fathom, its walls reacted to damage like living tissue. Shell impacts would scab over with liquid silicates, and moments later the wall beneath would be whole again. Only when the hurt was so sustained and so catastrophic would any site of damage be irreparable. Attackers found the wall reacting to them with spiked extrusions of living rock, or were swallowed whole as the stonework opened up beneath them. Against any conventional foe, the fortress would have been, for all intents and purposes, impregnable and indestructible.
But the Iron Warriors were not conventional foes.
Lord Dorn had chosen the living citadel as the site upon which to plant the Aquila, not as a symbol of Imperial dominance, but a seat of governance to be shared by all. He had brought the planet’s former rulers into the establishment of an ordered government, allowing the people to choose their own planetary governor, a respected civic leader named Endric Cadmus. Cassander smiled at the memory, thinking that perhaps some of the philosophy of the XIII Legion’s primarch had permeated the Imperial Fists after all.
Cassander and his fellow Imperial Fists had escorted the expeditionary iterators and remembrancers as they went from cities to far-flung townships, spreading word of the Emperor to a people ripe to embrace the Imperial Truth. It had b
een a glorious time, and when Lord Dorn announced that he was to lead the VII Legion to fresh campaigns, the populace had mourned his departure like the loss of a loved one.
He remembered the pride that filled him when the primarch had given him the solemn duty of standing with his battle company as sentinels to the newly compliant world, a potent sign that this was a world under the protection of the Imperial Fists. But that honourable gesture was to have consequences that not even Lord Dorn could have foreseen.
Cassander wiped dust from his scarred face and spat a mouthful of the wretched stuff to the ground, where it bubbled with a chemical hiss. His helmet was long gone; a bolt-round had punched through the faceplate and blown out in a spray of blood, bone and ceramite. Techmarine Scanion had died early in the fight, and without his direction the forge-servitors were of only limited use when it came to repair work. A few Mechanicum adepts remained, but they spent their days in the heart of the citadel, plumbing its secrets as though there were still a chance they might live to relay anything they might find.
Cassander’s features were careworn, as though abraded by the constant winds that scoured every smooth surface on this planet and gave it the texture of coarse sand. Eyes of deep brown that had seen the order of the galaxy overturned without any power to change it were deep-set and melancholic, his cheeks scar-blackened with the explosive passage of the bolt-round that had taken his helm.
When the order came to return to Terra, Cassander began preparations to depart immediately, but the sudden death of his vessel’s Navigator had left them stranded until a replacement could be despatched. The following day, word of the Warmaster’s treachery and the massacre on Isstvan V reached them, throwing Cassander’s world into free-fall.
Pride in an honourable assignment was replaced by frustration and bitter disappointment that they could not fight alongside their brothers, could not call Horus to account for his perfidy and punish those who had trampled their oaths of loyalty into the dust.
But the chance to make war on the traitorous allies of Horus had come soon enough.
The Iron Warriors made planetfall in the wake of a saturation bombardment that reduced the valley and the agri-settlements filling its fertile deltas to ash. Magma bombs and mass drivers boiled away the rivers and reduced fecund earth to arid dust. The Cadmean Citadel was left untouched, and Cassander still found it difficult to believe that such a precise bombardment was possible.
He knew why, of course.
The Iron Warriors could not pass up this chance to humble the sons of Dorn, and Cassander had rallied his men with grim certitude as the bulk landers of the IV Legion descended on towering columns of firelight.
The technological cunning of the ancient fortress builders, married to the artfully wrought geography and the courage of the defenders, had kept the Iron Warriors at bay for almost three months, but now Cassander’s defiance was almost at an end. With three-quarters of his Company slain, and thousands of mortal soldiers dead, he was running out of ways to fight. The citadel had few heavy guns remaining to keep the Iron Warriors from bringing their artillery superiority to bear and overwhelming the citadel’s inbuilt defence mechanisms.
The traitors could not be denied for much longer, but every day Cassander’s warriors stayed alive kept the enemy from redeploying and bringing their strength to bear elsewhere.
A poor measure of success, but it was all Cassander had left.
He shook off such pessimism, knowing it did not become a warrior of the Imperial Fists to wallow in self pity, and moved to the edge of the northernmost bastion. Once its gleaming ramparts had been a proud example of the military engineer’s art. Now they were chewed up ruins-in-waiting. Locris and Kastor crouched behind the largest nubs of dusty stone, golden giants amid the hundreds of dusty ochre-clad local militiamen. Cassander had broken up his few remaining squads, deploying his men throughout the defence to bolster each section of wall and provide strength of heart to the thousands of soldiers who fought alongside them.
The sky strobed with concussive impacts that buckled the air with their force. High explosives on ballistic trajectories flashed and screeched as their impact violence was dissipated by the void-umbra. The shields on the southern approaches were close to failing, but thankfully the enemy wasn’t concentrating fire there.
Locris looked up as Cassander hunkered down in the lee of the rampart, and Kastor gave him a nod of acknowledgement.
‘They’re eager today,’ said Kastor, as a thunderous detonation rocked the base of the wall. Kinetic dampers in the citadel’s plunging foundations transferred the power of the blast deep into the bedrock of the mountain and the smell of metal shavings and oily secretions wafted up from the silicate scabs forming over the craters. Rock fragments rained down onto the ramparts, blanketing the long line of soldiers in yet more red dust.
‘Too eager,’ agreed Locris. ‘Something’s happening, the pace has changed.’
Like Cassander, Locris went bareheaded; the same shrapnel fragment that split his battle helm in two had given him the long scar down his cheek and taken his left eye. The scar made him roguish, the eye piratical. Both were wounds to be avenged.
The plastron, pauldrons and greaves of Kastor’s armour were scorched black where the firestorm of an incendiary projectile had peeled the paint from its plates as he shielded a group of wounded soldiers with his body.
‘What do you think, captain? The Digger?’ asked Kastor.
‘I told you, Symeon’s squad spotted the Digger in the east today,’ said Locris. ‘This feels like Scrapper’s men.’
Cassander gripped the hilt of his sword and peered through a split in the rampart, where webs of connective stone tissue had failed to set, watching the uphill avalanche of burnished iron plate through a haze of dust. Smoke-wreathed artillery pits in sheltered batteries far below hurled high-velocity projectiles ahead of the climbing Iron Warriors, while mobile guns on walker platforms struggled to keep up with the assault force. This fresh attack was a salutatory reminder that Perturabo’s sons were warriors first and foremost, siege specialists second. Cassander watched their movements, fluid and aggressive, disciplined yet driven by core-deep fury.
Where had such raw hate come from?
They had taken to distinguishing between the Iron Warriors detachments by giving their commanders derogatory appellations based on their most apparent characteristics. The Digger’s men were bent-backed shovellers, methodical, precise and unstinting in their labours, the Malingerer kept his men in their dugouts as his artillery dropped tonnes of munitions on the citadel, the Voyeur liked to watch proceedings from a spike-topped blockhouse in the centre of the valley.
‘I think you’re right, Locris,’ said Cassander.
Unlike his fellow commanders, Scrapper liked to throw his men at the walls if so much as a sniff of an assault opportunity presented itself. Where other Iron Warriors displayed a measure of caution towards the citadel’s defences and an appreciation for the careful, step-by-step methodology of siege warfare, Scrapper liked to get his legionaries bloody in the swirling crucible of combat.
Cassander dropped back into cover as a whining solid slug zipped overhead.
‘Makes it easier, I suppose,’ noted Kastor. ‘His men have no fire discipline worth a damn.’
‘Maybe not, but they’re hard fighters,’ said Cassander. ‘We give them insulting names, but don’t ever underestimate them.’
‘Duly noted, captain,’ said Kastor, placing a fist in the centre of his scorched breastplate.
Locris held up a spoon-handled detonator trigger and said, ‘You want the pleasure of these ones, captain?’
Cassander risked another glance through the rampart as the citadel’s artillery pieces opened up on the advancing Iron Warriors. Those guns alone weren’t going to make much of a dent in the assault force, but any thinning of the ranks could only be a good thing.
‘You do it,’ he said. ‘You’ve more than earned it.’
Locris grinned
and mashed the trigger, detonating the last of the seismic mines dug into the northern slopes at the forefront of the Iron Warriors attack. Mushrooming blasts of tectonic shockwaves ripped a three-hundred-metre section of the mountain away and sent it tumbling downhill in a storm of pulverised rock.
Cassander relished the sight of scores of split-open bodies carried downhill in the raging avalanche, and pressed the throat bead of his borrowed vox.
‘All Fists – any movement in your sectors?’
Each of his section leaders replied in the negative, lending further credence to his growing certainty that this was Scrapper’s latest attempt to break the citadel open with a surprise assault. The tempo of the unequal artillery duel picked up as the Iron Warriors drew ever closer, climbing through the deep ditch carved by the seismic mines.
‘Symeon, Esdras, Phyros,’ said Cassander into his throat mic. ‘Re-deploy your men to the northern bastion immediately.’
The enemy artillery shifted their aim as the Iron Warriors closed the last hundred metres between them and the wall. Shells screamed on direct flight paths, slamming into the wall with pounding hammerblows that shook the foundations of the mountain itself. A pressure wave of impact blew up and over the wall and the heat of incendiaries burned at the silicate scabs fighting to resist the detonations.
Cassander knew this was the last chance he would have to blunt the assault force before the Iron Warriors were tearing at the defenders.
‘Wait until they reach the closest markers,’ he ordered, bellowing in a voice that could reach from one end of the Phalanx’s training halls to the other. ‘Make every shot count or it won’t be Perturabo’s whelps you need to worry about!’

The Trident Remade
Rubble and impact craters had made the wall scaleable, but the damned self-repair mechanisms were already remaking what the artillery had put asunder. From previous attempts at storming the citadel, Kroeger knew the wall would be flat and featureless in moments, so wasted no time in hurling himself onto the nearest hideously organic wound at the base of its structure.
