Obsessed with the desire to rid himself of the Fire Slayer Rune hidden in his chest, Gotrek Gurnisson, the greatest Slayer who ever lived, ventures deep into the strange alchemical domain of Hamon. Using their mysterious science of the aether, the Kharadron overlords of Barak-Urbaz propose to put an end to Gotrek's quest. But when the Ominous Moon rises and bloodthirsty, darkly evil bastards threaten to destroy the sky port, Gotrek stands against the most ancient enemy of his people - the greenskins. As his Alvian companion, Maleneth Witchblade, struggles to keep the Slayer alive, Gotrek plunges headlong into a bloody battle for survival that will take him into the dank, fungus-covered heart of Skragfang's hideout.
