Kurr

Kurr was a fang of Yeenoghu in the Labyrinth during the Rage of Demons in the 14 century DR.

Personality
Kurr suffered from a peculiar form of demon lord–spread madness: he felt guilty for all the people he had killed. He hoped to find someone who could kill him and his pack.

History
At the start of the Rage of Demons, Kurr led his pack of hyenas into the Labyrinth searching for Yeenoghu. He had them feast on the corpses of his slain victims, transforming them into gnolls. They wandered the area and Kurr succumbed to madness.
