Kathutet (Oblivion)

Quest
Kathulet is only in Oblivion for two reasons, to aid you on your way to defeating Mankar Kamoran, and to let you know that Deadra aren't just mindless killers. The quest he asks you to preform is simple, so it is advised that you simply do as he says instead of killing him, the fight against him is difficult.

Her appears as a helmetless deadra and speaks in a raspy tone.
