Belpheron

Belpheron is an ancient lich of great magical power referred to in Neverwinter Nights: Shadows of Undrentide as a villain who once tried to destroy Faerûn. He is the mentor of Heurodis and the original owner of the mummified hand, one of the four artifacts assigned to Master Drogan's guardianship by the Harpers and the only part of Belpheron's body that remained after he was destroyed.

In Neverwinter Nights: Hordes of the Underdark, the hero encounters Belpheron in Cania as one of Grimgnaw's followers and is forced to defeat him.
