The Black King is a tome found on the 12th level of the caves in the original Diablo. It tells the tale of Archbishop Lazarus, the presumed author, who released Diablo from his soulstone and kidnapped Prince Albrecht. It also tells the tale of King Leoric and his descent into utter madness.
It reads as follows:
- "Hail and sacrifice to Diablo, Lord of Terror and Destroyer of Souls. When I awoke my Master from his sleep, he attempted to posses a mortal's form. Diablo attempted to claim the body of King Leoric, but my Master was too weak from his imprisonment. My Lord required a simple and innocent anchor to this world, and so found the boy Albrecht perfect for the task. While the good King Leoric was left maddened by Diablo's unsuccessful possession, I kidnapped his son, Albrecht, and brought him before my Master. I now await Diablo's call and pray that I will be rewarded when he at last emerges as the Lord of this world."
