Nahkriin is an ancient Dragon Priest and the former high priest of the Dragon Cult as Alduin's personal prelate. Partway through the storyline, his ghost possesses a character's body after an ambush in his tomb, and he finally returns in the flesh for the Skuldafn arc after being empowered and resurrected by Alduin. He is a major villain and the principal antagonist from the Dragon Cult faction. As the ruling religious leader from "a time of unimaginable cruelty," Nahkriin is a fairly cut-and-dry villain character, though his motivations are explored somewhat towards the end of the storyline.

Voice should be deep and menacing with an American or Nordic accent. Voice actors should be able to match some of their lines to prerecorded audio to create a "possession" overlay effect. Must be able to pronounce dragon-language words. Tone is cruel and intelligent; speech is archaic and slightly unsteady due to Nahkriin's lack of proficiency in modern language.
