Skarbrand

Skarbrand the Exiled One was Khorne's favourite Bloodthirster until Tzeentch whispered him into swinging at the throne. He chipped the Blood God's armour. Khorne throttled the personality out of him, hauled him to the Brass Citadel's peak, and threw him for eight days across the Warp.

What landed was rage without a chain of command. Slaughter and Carnage are the axes. The wings are shredded souvenirs. He wrecks palaces of other gods as readily as mortal worlds, which is the closest thing Khorne has to a performance review for an exile.

He boarded Biel-Tan and lost to its Avatar, then tried to take Guilliman's head off Kairos's Blackstone until the Terran Crusade forced a temporary truce. Banishment did not make him smaller. It made him simpler.
