Khaine is distracted btw

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.
