Since the end of the Horus Heresy, Khârn has been an unstoppable and bloody avatar of Khorne. After the Battle of Skalathrax where he shattered his own Legion's unity, Khârn hunted the Eye of Terror as the head of a World Eaters warband, slaughtering any worthy enough to be killed in Khorne's name. Ten millennia later, during the 13th Black Crusade in 999.M41, his wrath was unleashed upon the Imperium of Man once more, as Khârn joined a few of the most insane of the Khornate Berserkers, battling those legions of the Emperor's warriors flocking to the defence of Cadia.
