Fulgrim - Apotheosis of Fulgrim: The Primarch of the Emperor’s Children hurled his brother aside, and Perturabo fell in a languid arc to land with a crunch of metal and crystal at the edge of the shaft. Blood trailed the air in a streaming red arc from Perturabo’s chest. The Lord of Iron lay unmoving, his body broken and lifeless. The attention of every Astartes within the chamber was irrevocably drawn towards the Primarch, for they recognised that an event of great moment was in the offing. The Phoenician was no longer the same being as had descended into the planet. He floated in the air above the shaft, which no longer poured its green torrent up to the restless darkness above, but simply radiated a fading glow of dying light. Fulgrim’s armour was shimmering with vitality, as though the light of a thousand suns were contained within him and strained to break free. The Primarch’s dark, doll-like eyes were twin black holes, doorways to heights of experience and sensation the likes of which could only be dreamed by madmen and those willing to go to any lengths to taste them.Just as Fulgrim was about to achieve his ultimate desire, Perturabo had regained enough of his former strength and rose to his feet, the maugetar stone in his hand. Perturabo walked towards Fulgrim, keeping the hand holding the maugetar stone extended over the shaft in the center of the chamber. Perturabo looked his brother in the eye for some hint of remorse, a sign that he regretted that things had come to this, something to show he felt even a moment of shame at plotting to murder his brother. He saw nothing, and his heart broke to know that the Fulgrim he had known long ago was gone, never to return. He had not thought it possible that anyone could plunge so far as to be beyond redemption. Perturabo knew that Fulgrim no longer wanted to be an angel, he wanted to be a god. He informed the Phoenician that Mankind had outgrown such beings a long time ago. Disgusted by Fulgrim's desires, Perturabo hurled the maugetar stone into the deep shaft.Suddenly, a barrage of Bolter fire erupted and a handful of Emperor's Children Astartes were pitched from their feet. Black-armoured Space Marines bearing a mailed fist upon their shoulder guards charged towards the Traitors. It was the Astartes of the X Legion, the Iron Tenth -- the Iron Hands. Soon the battle was joined, as Loyalist fought Traitor within the expansive chamber. The noose of battle was closing on the two Primarchs at its centre -- Perturabo locked on his knees, and Fulgrim hovering in the air as though bound to his brother by ties not even the call of war could break. The Iron Hands were mired in battle with the Emperor’s Children and Iron Warriors, zipping streams of fire blasting back and forth between them. During the battle, one of the Loyalist Astartes, the Raven Guard named Sharrowkyn, had acquired the fallen maugetar stone. He instinctively knew that if this stone was desired by Fulgrim, then it had to be destroyed. Taking a Bolter from a fallen Emperor's Children Astartes, he aimed the muzzle at the strange gold and black stone and pulled the trigger.The weakened Perturabo was renewed with the sudden release of his lifeforce from the Chaotic relic. Fulgrim’s body arched in sympathetic resonance, for the maugetar stone contained more than just the strength stolen from Perturabo by Fulgrim. It contained their mingled essences, a power greater than the sum of its parts, a power to fuel an ascent so brutal that only the combined life-force of two Primarchs could achieve it. Armour burned from Fulgrim’s body, flaking away like golden dust in a hurricane, leaving his monstrously swollen body naked and his flesh blazing with furnace heat. Spectral flames of shimmering pink and purple licked around his body, a hungry fire waiting to consume him the moment his focus slipped. As the Lord of Iron finally pushed himself upright and stood fully erect, he lifted Forgebreaker onto his shoulder. Fulgrim saw his death in Perturabo's eyes and grinned, knowing that his brother had to do it. Perturabo hefted Forgebreaker like a headsman at an execution and swung the mighty hammer in a wide arc, splitting the Phoenician's body wide open. It was done.Fulgrim’s body exploded under the impact of Perturabo’s warhammer, and the cry of release was a shrieking birth scream. An explosion of pure force ripped from the Phoenician’s destroyed flesh, filling the chamber of towers with a blinding light that was too bright to look upon, too radiant to ignore. Like a newborn sun, the wondrous incandescence was the centre of all things, a rebirth in fire, new flesh crafted from the ashes of the old. Every eye in the chamber was turned to the light, though it would surely blind them or drive them to madness. Through slitted fingers and shimmering reflections, the survivors of the fighting bore witness to something magnificent and terrible, an agonising death and violent birth combined. A figure floated in the midst of the light, and it took a moment for Perturabo to recognise the impossibility of what he was seeing. It was Fulgrim, naked and pristine, his body unsullied by any of the mawkish ornamentations with which he had defaced his flesh, as perfect as the day the Emperor had first conceived him. Fulgrim’s back arched and his bones split with gunshot cracks. His flesh, once so perfect, now ran fluid and malleable, his form moulding and remoulding as though an invisible sculptor pressed and worked him like clay upon a wheel. Fulgrim’s legs, extended like the man of Vitruvius, ran and lengthened, fusing together in a writhing serpent’s tail, the skin thickening and sheening with reptilian scales and segmented plates of chitinous armour. Perturabo took a step towards this thing being born from the death of his brother, all the while despairing that this was his brother.Perturabo had destroyed Fulgrim’s mortal shell. This was an immaterial avatar of light and energy, of soul and desire. What was being done here was an act of will, a creature birthing itself through its own desire to exist. Fulgrim’s face was a mask of agonised rapture, a pain endured for the pleasure it promised. Two obsidian horns erupted from Fulgrim’s brow, curling back over his skull, leaving his perfect face as unsullied as the most innocent child. Fulgrim ascended into Chaos, a prince of the Neverborn, a lord of the Ruinous Powers, the chosen and beloved Champion of Slaanesh. As the newborn Daemon Prince departed, the first of the Traitor Primarchs to achieve daemonic apotheosis, he left his brother with a cryptic message that they would one day meet again, and both brothers would yet renew their bonds. Lifting his hands into the air, a curtain of light rose up from the ground and Fulgrim and all of his Emperor's Children Chaos Space Marines disappeared in a flare of arcane teleportation energy.With the disappearance of the Emperor's Children, the Crone World of Iydris began to tear itself apart. The force at the heart of the world was no more. The strength of the lifeforces of the dead Eldar that had kept it safe was failing, and soon this planet would be swallowed by the unimaginable force of the supermassive black hole that lay at the heart of the Eye of Terror. Across the chasm, the remaining Iron Hands gathered up their wounded and fell back from the spreading fissures and heaving ruptures opening in the floor. They looked upon Perturabo with hatred, but decided to make their way off-world from the doomed planet. They knew that they could not fight the Lord of Iron and live through the encounter. Perturabo let the Iron Hands depart. Then he led his warriors out of the crumbling citadel. Once aboard his flagship the Iron Blood, Perturabo watched the final death throes of the Eldar Crone World.The Iron Blood strained to break orbit, but the force at the heart of the Eye of Terror was reasserting its grip on reality with a vengeance. Many of the smaller vessels of the Iron Warriors survivor fleet that had followed the Sisypheum had already been dragged within its embrace, swallowed by the black hole’s powerful energies. Only the capital ships had engines large enough to resist the inexorable pull, but even they were only delaying the inevitable. Perturabo's Triarchs stood patiently around their lord, awaiting his orders. The Lord of Iron informed them that he always moved forward, never backwards. They would go into the black hole. Though his senior commanders believed that it was suicide, the Lord of Iron informed them that Fulgrim had promised that the two brothers would meet again. The Iron Warriors were not meant to die within the Eye, and there was only one way onwards. His men moved to carry out his order, and the Iron Warriors fleet plunged deep into the heart of Terror.
