He is one of the five Istari, or Wizards, angelic spirits sent by the Lords of the West in human form to motivate the inhabitants of Middle-earth to resist the evil of Sauron. In the West he was the Maiar known as Olorin, and once served the Valar Manwe. To the Elves and Gondor he was known as Mithrandir, the Grey Pilgrim. To the east he goes not. At the conclusion of the War of the Ring he accompanied Frodo, Bilbo, Elrond, and Galadriel on a sea voyage to the Undying Lands.
