The Vampires of the Old World claim dominion over the mortal remains of all earthly creatures. To die is to surrender oneself to their power. Patient, cunning, devious, the Vampires work to conquer the lands of the living with ancient and corrupt sorcery. Should they succeed in their dreaded goals, the rays of the sun shall be forever suffocated by the night, and the age of men will be replaced by an age of the dead.

Set deep in the tunnels beneath the great city of Nuln, a dark evil has been unveiled. The foul skaven ratmen will stop at nothing to bring chaos to the world above and fulfill the prophecies of their dark god. Having enlisted as sewer–jacks in the vain hope of keeping a low profile, Gotrek and Felix find themselves thrust into the thick of the action as they battle to foil the skaven’s dark schemes.

Now back in the Empire following their sojourn overseas, Gotrek and Felix head north, to aid the men of the Empire in their fight against the invading Chaos hordes. Stopping off in Nuln, they meet up with dwarf engineer Malakai Makaisson, who is helping the Imperial war effort by transporting cannons to the frontline on his airship, the Spirit of Grugni. After a series of nasty accidents, it becomes clear that saboteurs are at work – can our heroes find the villains in time to save the day?
