Ulcaster's Dusty History Book is a special copy of the History of the Sisters of Light and Darkness found in the Ulcaster Dungeon in the Baldur's Gate: Enhanced Edition version of the game. In this version, it is the only book that will complete the Tomes of Magic side quest. It is found in a large pile of bodies at the heart of the dungeon (1400, 1050), protected by a Vampiric Wolf.
