Chamber of Blood is located inside Temple of Atal'Hakkar. It is divided into two separated sections, each accessed by a different doorway. The chamber works as an unholy church of sorts, where Atal'ai worshippers sit on rows of pews in the lower section and the upper section contains a blood altar, where Kazkaz the Unholy presides. Countless offerings of blood have been made here to the trolls' vile god, Hakkar the Soulflayer. Chamber of Blood is a dead-end room connected to the Hall of Masks, Den of the Caller, and The Butchery via narrow passages.
