Rauru

Rauru is an old Hylian man who is the Sage of Light and an architect of the Temple of Time. He is the last remaining Ancient Sage. Rauru shares his name with a town in The Adventure of Link. Rauru is introduced to the player when Link awakens from his seven-year slumber in the Chamber of the Sages deep within the Sacred Realm. Rauru explains to Link where he is, what has happened while he was asleep, and gives him the Light Medallion, a symbol of Rauru's power. In the manga, it is revealed that Rauru was only a spirit who lived on in the Chamber of the Sages. This trait seems to be shared with the other Sages.
