1st Grey Seer Thanquol appearance (in a novel).
In his introductions of the 2013 Trollslayer(Black Library Classics) and 2019 Trollslayer (Black Library 20th Anniversary Edition) William King revealed that :
He wrote Geheimnisnacht as a one-off story, in 1988, in which Gotrek was meant to die at the end, but later revised it based on his liking for the characters (Gotrek’s fake death in the story was initially written as permanent.). The story led to the commissioning of another by Games Workshop, and then another, which led to Wolf Riders and The Dark Beneath the World. The success of these three stories led to King being commissioned to write a full-length novel, which he approached by writing three novella-length stories in episodic format, which became The Mark of Slaanesh, Blood and Darkness, and Skaven’s Claw.
However, Games Workshop Books closed unexpectedly, and the publication of the novel was delayed until 1999, when it also included The Mutant Master and Ulric’s Children, which had previously been published in Inferno! magazine. The novel also added the prefacing excerpts from Felix’s journal.
