Leoric's Journal

 is a five-part tome in Act I of Diablo III. The parts are scattered between the Cathedral and the Halls of Agony.

The parts read as follows:

Part 1
Location: Cathedral, Level 3 and beyond, in any scribe's lectern

Quest: Reign of the Black King

"We have just arrived in Tristram, and I must say I'm a bit dismayed. This place is a backwater filled with serfs and an ancient, broken-down monastery, hardly fit for the king of Khanduras! I cannot fathom why Lazarus was so intent on this becoming our new seat of power."

Part 2
Location: Cathedral, Level 3 and beyond, in any scribe's lectern

Quest: Reign of the Black King

"A fetid, pallid malaise has fallen over the manor we now call home. Young Albrecht seems to be enjoying himself in our new home, however. Perhaps I am simply suffering from an imbalance of humors brought on by the recent change of clime."

Part 3
Location: Cathedral, Level 3 and beyond, or the Halls of Agony, any scribe's lectern

Quest: Reign of the Black King or The Imprisoned Angel

"I am convinced that some malevolent being is attempting to wrest control of my thoughts away from me. Voices direct me to horrendous acts, and there are times when I seem unable to control my body. Lazarus knows; this is certain. He looks at me strangely when he thinks me otherwise disposed."

Part 4
Location: The Halls of Agony, any scribe's lectern

Quest: The Imprisoned Angel

"Though my council begs me to reconsider, I will continue with the executions of those I find guilty of plotting against the kingdom. Perhaps they fear my eye will fall on them and discover their heinous, treasonous plans as well. Lazarus is the only one I can still trust."

Part 5
Location: The Halls of Agony, any scribe's lectern

Quest: The Imprisoned Angel

"I have finally rid myself of the dark influence seeking to subdue me, and now I see things as they truly are. This conspiracy among the insolent townsfolk to weaken me by stealing Albrecht away will not stand! Perhaps the heads of their women and children on pikes will bring them clarity..."
