The Great Book of Grudges (also known as the Dammaz Kron in the Dwarf language) is an ancient book passed down through the ages from one Dwarfen High King to the next. It is currently held by the reigning High King, Thorgrim Grudgebearer. The Great Book of Grudges is essentially a record of all the terrible wrongs and treacherous deeds ever perpetrated against the Dwarf race. The book is written in the blood of High Kings and only they have the authority to add new grudges or strike out grudges that have been avenged. Essentially, the Book of Grudges amounts to a very detailed recorded history of the Dwarfs. Being a symbol of the absolute lordship of the Dwarf High Kings, it is kept secret from the eyes of other races. In fact, few members of the outside world have even seen the tome, save for a small number of scribes from the Empire, only allowed access because of the longstanding alliance between the Empire and the Dwarfs.
