Compendium Tributis

An ancient artifact, the Compendium Tributis was a tome crafted by the gods themselves after the end of the Origin Wars. After their tribulations in wresting control of the world from the fiends, the gods detailed their experiences and secrets in the Compendium Tributis. Many have tried to discover the ancient tome, but most have failed.
The rakshasa, Kabar used the artifact to release his master, Demon Lord Zoul. However, Zoul was defeated and the artifact was seemingly lost in the destruction.
