For those who haven’t heard of the term before, a ‘maiar’ is basically a powerful being or spirit with Tolkien’s legendarium. The maiar have been around for thousands of years, and some of them even chose to take physical form and come across to Middle Earth. There are many characters in the Lord of the Rings trilogy who are actually mair, including the 5 wizards, of whom the audience can see Saruman the White, Gandalf the Grey and Radagast the Brown in Peter Jackson’s film adaptations, and Shadowfax the white steed, lord of all horses.
