The monstrous iron creature plucked the flaming spear from the air, black smoke and spitting embers drifting from its eyes and mouth as it spun the weapon and aimed it at Fulgrim's heart.

Fulgrim grinned as he felt the thrill of combat pulsing through every fibre of his being. Here was a foe that would truly test his mettle, for what being had he ever fought that had truly challenged him? The Laer? The Diasporex? The greenskin?

No, this was a creature with a power to match his own, a terrible god-like being that bore the heart of its fading race within its iron breast. It would not be baited or riled with petty insults, it was a warrior creature with one purpose and one purpose alone: to kill.

Such a one-dimensional aspect made Fulgrim sick, for what was life and death but a series of sensations to be experienced one after another. Without sensation what was life?

A wild exultation filled him and his senses seemed to rise to the surface of his skin. He felt every tiny gust of wind as it wound past his body, the heat of the creature before him, the coolness of the planet's atmosphere and the softness of the grass beneath him.

He was truly alive and at the height of his powers!

'Come on then,' snarled Fulgrim. 'Come on and die.'

The two beings leapt towards each other, Fulgrim's sword slashing down to meet the mighty creature's blade, which he now saw resembled a great sword, where once it had been a spear. Both blades met with a tearing shriek that echoed in realms beyond those of the five senses and an explosion of unlight that left those who saw it blinded. The roaring eldar god recovered first and its molten sword arced for Fulgrim's head.

He ducked, and slammed his fist into its midriff, feeling the hard impact on iron and the blistering heat that seared the skin from his knuckles. Fulgrim laughed with the pain, and raised his sword to block a murderous slash towards his groin.

The eldar god attacked with wild, atavistic fury, its blows driven by racial hatred and the ferocious joy of unbound emotion. Flames wreathed its limbs, and dark tendrils of smoke enveloped the two combatants as they struggled. Silver sword and fiery blade sparked and clanged as they traded blows, neither able to penetrate the other's defences.

Fulgrim felt his anger at this blazing monstrosity surge in his veins, its inability to do more than simply fight and kill offending his refined sensibilities. Where was its appreciation of art and culture, beauty and grace? Such a thing did not deserve the boon of existence, and his limbs filled with renewed strength, as though a new-found power flowed from his sword arm and into his flesh.

He could hear the sounds of battle all around him: bolter fire, cries of pain, whickering razor-discs from alien weapons, and howling screams, like the cries of the banshees of legend. He paid them no heed, too focused on his own fight to the death. His sword pulsed with a silver glow, streamers of light and power rippling along its length as he swung it, every strike delivered with a roar of ecstasy. The gleam of purple light from the pommel stone was strong, and he could see that the fiery gaze of his foe's eyes was ever drawn to it.

A wild idea took root in his mind, and though a powerful surge of denial washed through him at the thought, he knew that it was the only way to defeat his enemy quickly. He stepped in close to the flaming eldar god and hurled his sword high into the air.

Instantly, its burning gaze snapped upwards, the coals of its eyes homing in on the spinning blade. It drew back its arm to hurl its spear at the sword, but before it could throw, Fulgrim leapt towards it and delivered a thunderous right hook to its face.

Every ounce of his power and rage powered the blow, and he let loose a bellowing cry of hate as he struck. Metal buckled and an eruption of red light exploded from the eldar monster's head. Fulgrim's fist hammered through its helmet and into the molten core of its skull, and he cried out in agony and pleasure as he felt the blow smash from the back of its head.

The wounded creature staggered, its head a twisted ruin of metal and flame. Spears of red light streamed from its helmet, and the molten rivers of its blood blazed like phosphor against its iron skin. Fulgrim felt the pain of his maimed hand, but savagely suppressed it as he stepped in again and wrapped his hands around its neck.

The heat of its molten skin seared his flesh, but Fulgrim was oblivious to the pain, too intent on his foe's destruction. Plumes of red light streamed from the eldar god's face, the sound like a manifestation of the combined rage and heart of its creators. An age of regret and lust flowed from the creature, and Fulgrim felt the aching sadness of the necessity of its existence pour into him even as it poured out of the dying monster.

His hands blackened as he crushed the life from his enemy, the metal cracking with the sound of a dying soul. Fulgrim forced the creature to its knees, laughing insanely as the pain of his wounds vied with the powerful elation he felt in crushing the life from another being with his own bare hands and watching as the life fled from its eyes.

The sound of a great and terrible thunder built, and Fulgrim looked up from his murder to see a graceful bird of fire carve its way across the heavens. He released his hold on the dying eldar creature and punched the heavens as the Firebird streaked overhead, followed by a host of Stormbirds and Thunderhawks.

Fulgrim returned his gaze to his defeated foe as whipping light and noise poured from it like the nuclear fire blazing at the heart of a star. The light of the creature's death flared, and its body exploded in a thunder of hot iron and molten metal. Fulgrim was hurled through the air by the screaming explosion, and he felt the touch of its power sear his armour and skin.

The released essence of a god surrounded him. He saw a whirling cosmos of stars, the death of a race and the birth of a bright new god, a dark prince of pleasure and pain.

A name formed from the raw sound of ages past, a bloody paean of birth and a wordless shout of unbound sensation building into a mighty roar that was a name and a concept all at once… Slaanesh!

Slaanesh! Slaanesh! Slaanesh! Slaanesh! Slaanesh! Slaanesh! Slaanesh! Slaanesh!

Even as the name formed, Fulgrim slammed into the ground and laughed as the Emperor's Children descended to Tarsus on wings of fire. He lay still, broken and burnt, but alive, oh, how he was alive! He felt hands upon him and heard voices begging him to speak, but he ignored them, suddenly feeling an aching longing seize him as he realised he was unarmed.

Fulgrim pushed himself unsteadily to his feet, knowing that his warriors surrounded him, but not seeing them or hearing their words. His hands throbbed and he could smell the scorched ruin of his flesh, but all his attention was fixed on the silver glow that split the night.

His sword stood upright in the grass, its blade having come down point first after he had hurled it into the air. It shimmered in the darkness, the silver blade reflecting the light of the Firebird and the descending assault craft. Fulgrim's hands itched to reach out and grip the sword once more, but a screaming portion of his mind begged him not to.

He took a faltering step towards the weapon, his hand outstretched, though he could not remember consciously ordering it to do so. His blackened fingers trembled and his muscles strained as though forcing their way through an invisible barrier. The siren song of the sword was strong, but so was his will, and what remained of his vision of the dark god's birth stayed his hand for the moment.

Only through me will you achieve perfection!

The words thundered in his head, and memories of the battle surged powerfully in his mind, the fire and the hunger to kill, and the wondrous elation of a god's death by his own hands.
