Grey Seer Thanquol is without a doubt (in his mind) the greatest nemesis of the Slayer, Gotrek Gurnisson and his companion Felix Jaeger. He, and his stalwart Rat Ogre bodyguard, Boneripper, have engaged in innumerable nefarious schemes and adventures across the World-That-Was, including...

Claiming the deadly artefact known only as Wormstone to poison the city of Altdorf; the assassination of the Prophet of Sotek in a foreign land of giant lizards and endless jungle; leading an army against the dwarfs of Karak Angkul; and unintentionally finding themselves body-swapped.

Will Thanquol find victory at long last, or will the incompetence of his underlings hold him back yet again?

This omnibus contains three novels: Grey Seer, Temple of the Serpent and Thanquol's Doom, and two short stories: 'Mind-Stealer' and 'Thanquol Triumphant'.
