A mysterious and controversial prophet. His real name never became known.
He claimed to see visions of the past, present and future, which he wrote; but never knowing when they belonged. The Watcher spent his life on secret, secluded Ages. In 4500 he wrote down his visions in he work called "Words". It was believed that the queen consort of King Ji was his daughter. In any case, she was very interested in his writings and convinced Ji to do the same.
His prophecies didn't catch on well, but after some events, he became more and more popular, depending on how accurate his followers viewed his visions. Over the course of time a large number of his books were printed, and remained throughout all he D'ni City.
It is said that King Jaron was motivated by the prophecies of the Watcher ("because of tunnels D'ni has changed forever") and was obsessed with expansion and exploration of the cavern, never explaining his drive.
By the time of King Asemlef, the people were confused and divided among the teachings of the Watcher, Nemiya, Gish, Tevahr and others. By the time of Kerath, the original beliefs of Ri'neref had been forgotten.
