End Times of the Ghouls
Extremely illegal to illegal to possess or read, End Times of the Ghouls is one of the "bone books" that open the Bone Room of the Understacks. It is made from plates of bone that have been bound together into a book with pieces of sinew. The book is written in an unfamiliar language that is scratched into the bone itself, although the spine has a label translating the title into Common.
