Nefarious Grey Seer Thanquol, skaven sorcerer and arch-enemy of Gotrek & Felix, embarks on his own adventure to recover the deadly artefact known only as Wormstone. With this dread substance, he plots to poison the city of Altdorf and rise to power in the eyes of his masters amongst the Council of the Thirteen.



After a series of failures, Grey Seer Thanquol is offered a chance to redeem himself by going to the island of Lustria to kill the Prophet of Sotek. Dogged by assassins and stranded in a foreign land of giant lizards, temple cities and endless jungle, Thanquol must use all of his cunning and magic if he is to come out alive.



Upon his return to the Old World, the ambitious Grey Seer Thanquol is coerced into leading an army against the dwarfs of Karak Angkul. Renowned for its engineer clans, this city will not fall easily, but the true object of Thanquol’s fascination is their secret artefact of incredible power which he believes will assure his ascension to the Council of Thirteen. His efforts are thrown into disarray when the infamous skaven Ikit Claw usurps control of the army for his own nefarious schemes, and so Thanquol must act quickly before the warlock can unleash his ultimate weapon – the Doomsphere.



Grey Seer Thanquol commands a mighty skaven army in conquest of his foes (leading from the rear, of course). Victory is at hand... nothing can go wrong. Can it?
