He is [[Fulgrim]]'s champion, the Soulthief, and the Scion of [[Chemos]]. His name is whispered and cursed across both time and space, a peerless blademaster who even death cannot threaten. He is [[Lucius the Eternal]], blessed by [[Slaanesh]] and the greatest swordsman of all the [[Traitor Legion|fell Legions ]] imprisoned within the [[Eye of Terror]]. With his armies exhausted by unending war and consumed by their own twisted iniquities, Lucius turns to an erstwhile brother of the [[Emperor's Children]] to rebuild his strength. Faced with betrayal from without and even from within his own flesh, will Lucius discover something that even one who cannot know death should fear?{{Fn|1}}
