Kossolax the Ravager

Kossolax the Ravager is a Chaos leader of the Foresworn, formerly Sergeant Solax of the World Eaters’ 3rd Assault. His transformation was completed by the nails, after which he repudiated the name Solax. He treats its use as an offence and answers it with violence.

The Foresworn embody his response to the structure of a Legion. They combine mutants, who handle logistics, with berzerkers, who lead the charge, under a lord who believes he can draw on Khorne without being overwhelmed. Kossolax attacked Agripinaa during the 13th Black Crusade and returned after Cadia burned. He later styled himself Lord Regent of the XII. The Conqueror instead answered Angron, and Kossolax withdrew while his lieutenants died on the bridge.

At Hyades he lost an army. He retains his ship and his title, and he has survived encounters with primarchs on more than one occasion.
