Far to the north of the Empire lies the dreaded Chaos Wastes, home of the Dark Powers and their mutated servants. The frozen city of Kislev is all that stands between this gateway to hell and the civilised world. Two brothers in arms find their destinies thrown into turmoil as their fight against the hordes of Chaos rips them apart. Such is the mutating power of this fell land that the strongest of friends can soon turn to the most bitter of enemies. No quarter is asked and none is given as they race towards a final cataclysmic showdown.
