Diinkarazan
Diinkarazan is the derro deity of vengeance. Twin of Diirinka.
Some believe him to be held in the Prison of the Mad God somewhere in the Abyss -- a plane thought to be a whirling vortex of gases and stones.
The adventurers encountered the undead Buppido who seemed to believe he was Diinkarazan incarnated.
From Dorhun, the adventurers learned of the twin derro gods Diirinka and Diinkarazan. They learned that the evil and chaotic Diinkarazan is the god of vengeance.
