Kethendtir

Kethendtir was a brown dragon living in a cave in the Dawning Woods. He had amassed a number of kobold and dragonborn allies, and used them to raid caravans and travelers. Eventually, Tol Sigurn hired Tephra, Gryff, Nuraya, Ro, and Harthur Grai to slay him. Kethendtir put up a fight, but in the end he and his allies were killed.
