To the north the armies of Chaos stand united under the direction of Tzeentch, the lord of change, rallying together with the Dark Elves and Orcs to plunge the old world into war. Guided by the god Loec, Lynian Shadowspear is coerced into helping a servant of Sigmar to stop an evil plot perpetrated by the forces of Chaos. Along with a mysterious Knight and an old dwarf the following gets entangled in the great Chaos incursion.

On the other side of the old world the legendary Druchii assassin Ravor Vileblade and his unwilling servant make their way toward Kislev under orders of the Witch King himself to hunt down and kill Lynian at all costs, but are sidetracked by an ambitious Orc and a cryptic follower of Tzeentch who become determined to use their new allies to their own ends.
