Derendil

Derendil was a quaggoth inhabiting the Underdark during the Rage of Demons.

Personality
Thank to the influence of the demon lord Fraz-Urb'luu, Derendil believed himself to be an elven prince of the Nelrindenvane kingdom in the High Forest who was polymorphed into a quaggoth by an evil wizard. Nobody could convince him that his story was false.

History
Derendil was captured by drow slavers of Velkynvelve during the Rage of Demons.
