The Book of Kaza is a famed tome written by the lich, Kaza. It is said to deal with the darkest secrets of necromancy, though the pages appear to be blank when you look at it. Kaza was destroyed during the upheaval of Nethril's final days. The book was brought to what is now Amn by Kaza's disciples. How it has come to its present location after so many years is anyone's guess.
