I am Rauru, one of the ancient Sages... Ages ago, we ancient Sages built the Temple of Time to protect the entrance to the Sacred Realm... This is the Chamber of Sages, inside the Temple of Light... The Temple of Light, situated in the very center of the Sacred Realm, is the last stronghold against Ganondorf's evil forces. The Master Sword--the evil-destroying sword that you pulled out of the Pedestal of Time--was the final key to the Sacred Realm.
