The Blue Wizards (or the Ithryn Luin) were two notoriously mysterious characters of Middle-earth; so-named because they both wore sea-blue robes. These Istari were only hinted at in The Hobbit and The Lord of the Rings, where Gandalf and Saruman, respectively, mention that there are five Wizards. However, other writings of Tolkien have more to say: In Tolkien's Of the Rings of Power and the Third Age we are told that aside from Curunír (Saruman), Mithrandir (Gandalf), and Radagast, there were "others of the Istari who went into the east of Middle-earth, and do not come into these tales." Tolkien also writes in Unfinished Tales that the two Wizards were sent to the East. Their names in Valinor were Alatar and Pallando, and they were Maiar of the Vala Oromë.
