Anglor's Ghost was a Bosmer conjurer who resided in the Shivering Isles in the ruined city Vitharn. His ghost can be found in the chapel preaching to a small number of the residents, when the Hero is searching for the Dagger of Depletion.
Years ago, the fortress of Vitharn was attacked and overrun by invading fanatics. Upon his death, Count Cirion was visited by Sheogorath who cursed him and the rest of the fort's inhabitants for their cowardice and miserably poor defense. Lord Sheogorath forced them to relive their last moments forever.
