Rauru

Rauru, also known as Kaepora Gaebora when in his owl form, is a recurring character in The Legend of Zelda series. He is one of the ancient Sages of Hyrule, specifically the Sage of Light. During the Era of Chaos and shortly before the Kingdom of Hyrule was established by the royal descendants of the goddess Hylia's mortal incarnation, Rauru built the Temple of Time over the remains of the Sealed Temple that was located deep within the Faron Woods in the Faron Province. In doing this, he protected the Triforce from the chaotic Interloper War being fought over its ownership at the time. Rauru named the temple after the Temple of Time from the legends of the events of Skyward Sword about a hero who had wielded the Master Sword and traveled between two time periods. He chose to remain within the Temple of Light, situated in the center of the Sacred Realm, only leaving it in the form of the massive, wise and watchful owl known as Kaepora Gaebora. Knowledge of the Sacred Realm passed onto the Sheikah tribe and Rauru's name faded into obscurity. In the events of Ocarina of Time, after Link defeats Gohma in a failed attempt to save the Great Deku Tree, he leaves the Kokiri Forest and has his first encounter with Rauru, who awaits him in his owl form as Kaepora Gaebora at the edge of the woods. The owl gives him encouragement on the adventure the Great Deku Tree has tasked him with and advises him to visit Princess Zelda at Hyrule Castle before leaving with a promise that they will meet again.
