This betrayal would stain forever the honour of the Astartes, no matter the outcome.
Men will fear us from this day onwards, and they will be right to, thought Ferrus.
He heard the cries of jubilation behind him, but it was some moments before their substance penetrated his killing rage. He crashed the skull of a warrior of the Sons of Horus in his mighty fist and turned to see the welcome sight of an aerial armada of gunships dropping from orbit.
'My brothers!' he yelled triumphantly as he recognised the familiar iconography of his fellow loyalists. Alpha Legion Thunderhawks screamed over the battlefield, and the midnight-skinned vessels of the Night Lords swooped in to take position on the flanks to envelop the Warmaster's forces. Word Bearer Stormbirds howled in on screaming jets, the gold wings on the glacis of their craft shimmering as though afire in the glow of battle. Heavy transports of the Iron Warriors slammed into the Urgall Depression and disgorged thousands of warriors, who immediately began fortifying the landing zones with armoured barricades and looping coils of razor wire.
Tens of thousands of his fellow Astartes poured onto the surface of Isstvan V, and in a single stroke, the loyalist force was more than doubled in size. Ferrus punched the air in righteous vindication as he watched the power and might of his brothers' Legions fill the black desert behind him, their warriors, fresh meat for the battle.
His vox-unit chimed urgently as a ripple of fear visibly passed along the traitor lines at the sight of such a terrifying display of martial power. His practiced eye could see that the traitor forces had lost their stomach for the slaughter, entire cohorts pulling back from their prepared positions in dismay. Even the Dies Irae was retreating, the mighty Titan cowed in the face of such overwhelming force.
Ferrus saw the distant form of Mortarion ushering his warriors back towards the rained fortress, and even Angron was retreating, his bloodstained World Eaters like some monstrous, bloody tribe of head-hunters. But the Emperor's Children…
The smoke parted before him, and Ferrus saw what he had been looking for ever since he had set foot on this damned planet.
Clad in shimmering armour of purple and gold, he saw Fulgrim.
His former brother drew his most debased followers to him, waving them back to the black walls with long sweeps of a glittering silver blade. A long haft of ebony, worked with silver and gold extended behind his shoulder, and Ferrus smiled grimly as he realised that his brother had also understood that the fates had ordained this duel must take place upon the blasted plain of Isstvan V.
Twisted freaks in flesh-covered armour surrounded the Primarch of the Emperor's Children, and a monster with red, seared flesh attended at his right hand. Only now, at the end, did Fulgrim dare to reveal himself.
Even as Ferrus finally saw Fulgrim, he knew that his brother too was aware of him. He felt hate and betrayal rise in him like a suffocating wave.
The traitors were falling back from the loyalists with increasing speed, leaving thousands of corpses behind them, both friend and foe. The scale of the slaughter was not lost on Ferrus, and though his blood sang with this victory and his imminent confrontation with Fulgrim, he was not blind to the fact that the loyalist Legions had suffered appalling casualties to win it.
He watched the enemy line melt before him, the loyalist warriors exhausted by the furious battle, stumbling as their enemy fled before them. He called his Morlocks to him before opening a channel to Corax and Vulkan.
'The enemy is beaten!' he shouted. 'See how they run from us! Now we push on, let none escape our vengeance!'
Grainy static washed through the reply, Corax's words almost lost amid the rambling thunder of explosions and the descent of yet more allied drop-ships.
'Hold, Ferrus! The victory may yet be ours, but let our allies earn their share of honour in this battle. We have achieved a great victory, but not without cost. My Legion is bloodied and torn, as is Vulkan's. I cannot imagine yours has not shed a great deal of blood to carry us this far.'
'We are bloodied, but unbowed,' snarled Ferrus, watching as the distant figure of the fabulously bedecked Fulgrim climbed to the top of a jagged spur of black rock and spread his arms in blatant challenge. Even from hundreds of metres away, the mocking smile twisting his features was clearly visible.
'As are we all,' put in Vulkan. 'We should take a moment to catch our breath and bind our wounds before again diving headlong into such a terrible battle. We must consolidate what we have won and let our newly arrived brothers continue the fight while we regroup.'
'No!' shouted Ferrus. 'The traitors are beaten and all it will take is one final push to destroy them utterly!'
'Ferrus,' warned Corax, 'do not do anything foolish! We have already won!'
Ferrus snapped off the vox-channel and turned to face the surviving Morlocks of his bodyguard. A half century of Terminators surrounded him, their clawed gauntlets crackling with blue arcs of energy and their proud stances telling him they would follow whatever order he gave, whether it be to retreat or to march into the hell of battle once more.
'Let our brothers rest and lick their wounds!' he yelled. 'The Iron Hands will let no others have the satisfaction of settling our affairs with the Emperor's Children!'
Fulgrim smiled as Ferrus Manus renewed his attack into the heart of the defensive lines atop the Urgall Depression. Backlit by the flaring strobe of battle, his brother was a magnificent figure of vengeance, his silver hands and eyes reflecting the fires of slaughter with a brilliant gleam. For the briefest second, Fulgrim had been sure that Ferrus would pause to muster with the Raven Guard and Salamanders, but after his daring challenge atop the rock, there would be no restraining his brother.
Around him, the last of the Phoenix Guard awaited the blunt wedge of the Iron Hands, their golden halberds held low and aimed towards their foes. Marius and his wailing sonic weapon howled in anticipation of the combat, and Julius, almost unrecognisable with his skin burnt from his bones, ran a blistered tongue around the lipless ruin of his mouth.
Ferrus Manus and his Morlocks charged through the shattered ruin of the defences, his black armour and their burnished plates scarred and stained with the blood of enemies. Fulgrim's fixed smile faltered as he truly appreciated the depths of hatred his brother held for him and wondered again how they had come to this point, knowing that any chance for brotherhood was lost.
Only in death could this end.
The retreat of the Warmaster's forces appeared ragged and faltering, exactly as Horus had planned it. Warriors streamed back from the front lines of battle in determined groups, their spirits apparently broken, but gathering in knots of resistance behind shelled ruins and fire-blackened craters.
The Iron Hands pushed through the defences, the bulky Terminators unstoppable in their relentless advance. Lightning crackled from the claws of their gauntlets and their red eyes shone with anger. The Phoenix Guard braced themselves to meet the charge, fully aware of the power of such mighty suits of armour.
Marius released a howl of ecstatic joy, and his bizarre weapon amplified it into a screeching wail of deadly harmonics that ripped through the ground in a roaring sonic wave to explode amongst the front ranks of the Morlocks.
The giant warriors were torn apart in a clashing shriek of aural power as the apocalyptic noise made play of their armour and butter of their flesh. The Emperor's Children screamed in pleasure at the sound, their enhanced senses and augmented brain paths rendering the discordant sounds into the most vivid sensations imaginable.
'When they come,' shouted Fulgrim, 'leave Ferrus Manus to me!'
The Phoenix Guard answered with a terrible war cry and leapt to meet the Morlocks in a searing clash of blades. Electric fire leapt from the golden edges of the halberds and claws of the warriors, and a storm of light and sound flared from each life and death struggle. The battle engulfed the Primarch of the Emperor's Children, but he stood above it, awaiting the dark armoured giant who strode inviolate through the lightning shot carnage
as brothers hacked at one another in hatred.
Fulgrim nodded in greeting as Ferrus reached towards a sword belted at his waist, and he smiled as he recognised Fireblade's hilt.
'You remade my sword,' said Fulgrim, his voice cutting through the atrocious din of fighting. Though the ferocious battle between the Morlocks and the Phoenix Guard surrounded them, neither primarch's praetorians dared approach them, as though aware that to transgress this fateful confrontation would be a heinous crime.
'Only to see you dead by a weapon forged by my own hand,' spat Ferrus.
In response, Fulgrim sheathed his silver sword and reached behind him to unlimber the great warhammer held at his back. 'Then I shall do likewise.'
The great weight of Forgebreaker, the weapon his own skill and energies had crafted beneath the peaks of Mount Narodnya, felt good in his hands as he descended the rock to face his erstwhile brother.
'It is fitting we face one another with the weapons we forged long ago,' said Fulgrim.
'I have long waited for this moment, Fulgrim,' replied Ferrus, 'ever since you came to me with betrayal in your heart. For months I have dreamt of this reckoning. Only one of us will walk away from this, you know that.'
'I know that,' agreed Fulgrim.
'You betrayed the Emperor and you betrayed me,' said Ferrus, and Fulgrim was surprised to hear genuine emotion in his brother's voice.
'I came to you because of our friendship, not despite it,' answered Fulgrim. 'The universe is changing, the old order upset and a new dawn approaching. I offered you the chance to be part of the new order, but you threw it back at me.'
'You sought to make me a traitor!' snarled Ferrus. 'Horus is mad. Look at all this death! How can this be right? You will hang from Traitor's Gibbet for this sedition, for I am the Emperor's loyal servant and through me his will and vengeance will be done.'
'The Emperor is a spent force,' snapped Fulgrim. 'Even now he whittles away on some trivia in the dungeons of Terra while his realm is in flames. Are those the actions of a being fit to rule the galaxy?'
'Do not think you can win me to your cause, Fulgrim. You failed once and you will not get a second chance.'
Fulgrim shook his head. 'I am not offering you a second chance, Ferrus. It is already too late for you and your warriors.'
Ferrus laughed at him, but he could sense the despair in it. 'Are you mad, Fulgrim? It's over. You and the Warmaster are defeated. Your forces are routed and the power of another four Legions will soon crush your attempt at rebellion utterly.'
Fulgrim was unable to keep the sensations seething in his head contained any longer and he shook his head as he savoured his next words. 'My brother, how naive you are. Do you really think Horus would be foolish enough to trap himself like this? Look to the north and you will see that it is you who are undone.'
The forces of the Raven Guard and Salamanders fell back in good order to the drop zone, where their reinforcements were deploying to join the fight. The drop-ships of the Iron Warriors, armoured bastions connected by high walls of spiked barricades, formed an unbroken line of grim fortifications on the northern slopes of the Urgall Depression.
A force larger than that which had first begun the assault on Isstvan mustered in the landing zone, armed and ready for battle, unbloodied and fresh.
Corax and Vulkan led their forces back to regroup and to allow the warriors of their brother primarchs a measure of the glory in defeating Horus, dragging their wounded and dead with them. The victory had been won, but the cost had been steep indeed, with thousands of all three Legions lost to the betrayal of the Warmaster. Horus's forces were in retreat, but there would be no celebration of the slaughter, no joyous victory feasts or glorious days of remembrance, only another sad scroll added to a banner that would never again see the light of day.
Scorched tanks rumbled alongside the Astartes, their ammunition expended and their hulls battered by the impact of shot and shell.
Unanswered vox hails requested medical aid and supply, but the line of Astartes at the top of the north ridge was grimly silent as the exhausted warriors of the Raven Guard and Salamanders came to within a hundred metres of their allies.
A lone flare shot skyward from inside the black fortress where Horus had made his lair, exploding in a hellish red glow that lit the battlefield below like a madman's vision of the end of the world.
And the fire of betrayal roared from the barrels of a thousand guns.
Fulgrim laughed at the stunned look on Ferrus's face as the forces of his ''allies'' opened fire upon the Salamanders and Raven Guard. Hundreds died in the fury of the first moments, hundreds more in the seconds following, as volley after volley of bolter fire and missiles scythed through their unsuspecting ranks. Explosions flashed to life in their midst, vaporising warriors and tearing through tanks as the force of four Legions ripped the beating heart from the first wave of loyalists.
Ferrus Manus watched in mute horror as he saw a storm of fire engulf Corax, and a titanic explosion mushroom skyward from where Vulkan stood in astonished outrage at what was happening.
Even as terrifying carnage was being wreaked upon the loyalists below, the retreating forces of the Warmaster turned and brought their weapons to bear on the enemy warriors within their midst. Hundreds of World Eaters, Sons of Horus and the Death Guard fell upon the veteran companies of the Iron Hands, and though the warriors of the X Legion continued to fight gallantly, they were hopelessly outnumbered and would soon be hacked to pieces.
Ferrus Manus turned to face Fulgrim, and the Primarch of the Emperor's Children could see the despair etched into his brother's features, his silver eyes dull and lifeless. To have so great a victory snatched away in an instant must be the most sublime sensation. Fulgrim almost wished to switch places with his brother just to taste that feeling for himself.
'Only dismal defeat and death await you, Ferrus,' said Fulgrim. 'Horus has commanded your death, but for the sake of our past friendship I shall plead your case to him if you throw down your arms. You have to surrender, Ferrus. There is no escape.'
Ferrus Manus tore his eyes from the slaughter of the loyalist forces, his teeth bared with the volcanic fury of his home world.
'Maybe not, traitor, but only dishonour holds any terror for me,' spat Ferrus. 'The Emperor's loyal warriors will not surrender to you, not now, not ever. You will have to kill every last one of us!'
'So be it,' said Fulgrim, launching himself towards Ferrus Manus, swinging his mighty warhammer. The primarchs' weapons, forged in brotherhood, but wielded in vengeance, met in a blazing plume of energy, and the battlefield was illuminated for hundreds of metres by their ferocious energies.
The two primarchs traded blows with their monstrously powerful weapons, the strength to defeat armies and topple mountains unleashed as they fought like gods forced to end their dispute in the realm of mortals. Ferrus Manus wielded his flaming blade in fiery slashes, his every blow defeated by the ebony hafted hammer he had borne in countless campaigns.
Fulgrim swung his hammer in great, looping arcs, its heavy head powerful enough to crush the armour of a Titan to paste. Both warriors fought with the hatred only brothers divided can muster, their armour dented, torn and blackened by the fury of their conflict.
To fight an opponent of such magnificence was a privilege, and Fulgrim savoured every clash of hammer and sword, every fiery line cut across his flesh and every grunt of pain torn from his brother's mouth as Forgebreaker glanced his armour. They circled in the midst of cries of pain and roaring savage glee, the Morlocks of Ferrus Manus slain, but for a last few desperate heroes.
Ferrus cut the shoulder guard from Fulgrim's armour and spun inside his guard to deliver a lethal thrust towards his groin. Fulgrim stepped to meet the blow, batting aside the tip of the fiery sword with the haft of Forgebreaker, and hammering the warham-mer's head towards Ferrus's skull.
The Primarch of the Iron Hands took the blow, dropping to one knee and lashing out with his blade as blood str
eamed from the terrible wound in his temple. The sword's fiery tip cut across Fulgrim's stomach, opening his armour and tearing through his flesh. The pain was indescribable, and Fulgrim fell back, dropping his hammer as his hands sought to stem the blood pouring from his body.
Both primarchs faced each other on their knees through a haze of pain and blood, and Fulgrim once again felt an ache of sadness well within him. The pain of his wounds, and the sight of his brother's broken skull coated in blood, tore a window into his mind. The sensation was like a powerful gust of fresh mountain air, clearing away the fog that had wrapped him in a suffocating embrace for so long that he no longer noticed it until it was gone.
'My brother,' he whispered, 'my friend.'
'You have long since lost the right to call me friend,' snarled Ferrus, pushing himself to his feet and staggering towards Fulgrim with Fireblade raised to smite him.
Fulgrim cried out, and his hand leapt unbidden to his waist as the flaming blade carved a burning path towards his neck. Silver steel flashed as he drew the sword he had taken from the Laer temple and blocked the descending weapon. Ferrus's sword hissed and spat as it bit into the silver blade, the Primarch of the Iron Hands' strength forcing the blazing metal, centimetre by centimetre, towards Fulgrim's face.
'No!' cried Fulgrim. 'This is not right!'
The amethyst stone at the hilt of Fulgrim's sword pulsed with an evil light, bathing Ferrus Manus's face in a leering purple glare. Energy streamed from the blade, and musky smoke billowed around them, deadening sounds and obscuring sight. Fulgrim felt a monstrous presence swell around him, its power and nameless essence more intoxicating and dreadful than anything he could ever have imagined.
Diabolical strength flooded his limbs and he pushed against the power of Ferrus Manus, feeling his brother's surprise at his resistance. With a cry of animal rage, he surged to his feet and hurled Ferrus Manus back, spinning and lashing out with his sword.
