Gandalf

One of Tolkien’s most iconic characters, Gandalf the Grey (later Gandalf the White), known to the elves as Olórin or Mithrandir, is an angelic Maiar or Istar (Wizard), dispatched to Middle-earth from the undying lands in the Third Age to combat the threat of Sauron. Olórin told the Valar that he feared Sauron too much to to go, but Manwë said that was all the more reason to go: that he might conquer fear. Olórin took the form of an old man with a grey beard named Gandalf. Ancient and wise, Gandalf loves elves, and has sent them beautiful visions to instill wisdom in their hearts. He joined Thorin and his company to reclaim the Lonely Mountain from Smaug, helped form the Fellowship of the Ring to destroy the One Ring, and led the Free Peoples in the final campaign of the War of the Ring. To the hobbits, however, he’s just an eccentric, troublemaking old man.
