Abaddon the Despoiler plots to find a way to force Kharn the Betrayer, the infamous Chosen of Khorne, to join his Thirteenth Black Crusade against the Imperium.

Kharn the Betrayer, the Chosen of Khorne, is a force unchained and unbowed. Leading a band of ferocious berzerkers, Kharn follows the Red Path, bringing battle and bloodshed to all who stand in his way. As Abaddon the Despoiler's Thirteenth Black Crusade grips the galaxy, the Warmaster seeks to yoke Kharn's strength and barbarity for his own ends, but it soon becomes clear that the champion of the Blood God will not kneel easily. In his defiance, Kharn takes a bloody path that will lead him into conflict not only with the Imperium but also the Black Legion - and none will escape the carnage that follows.
