The Cult of the Watchers are a mysterious group that worship entities they refer to as the Watchers. The Cult was formed after the death of the Intoners in A.D. 1000 by One, in honor of his sister and the watcher Gabriel. The symbol of the Cult are the Three-Eyed Twins, One and his sister together as one.
The cult is responsible for the creation of the Seal and Goddess system that protects the world from the Seeds that would bring destruction upon it. It was led by One until he was exiled. Later, his children and their descendants would lead the cult, as High Priests or Priestesses. The followers of the cult are infected by the Red Eye disease, which eventually turns them into mindless drones, robbed of any free will, with their only purpose being to do the Watchers' bidding. The cult itself is composed of mages with abilities that draw upon the powers of the dark arts.
