[Source] The Unseen Elder, whose true name is never revealed, is one of the unseen elders, very old higher vampires that have inconceivable powers and serve as a sort of leader figure for their brethren. The Unseen Elder of Toussaint is guarding the gate between the realm of the vampires and the human world. He is extremely aggressive towards everything that enters his domain, and even other higher vampires must have a very good reason to disturb him.
