Auru is one of the members of "The Group" in The Legend of Zelda: Twilight Princess, and could be called the oldest out of them. He is fairly knowledgeable about the desert and the evils that it used to house (or, indeed, still does), and appears to have known the sages who guard the Mirror of Twilight at some point; aside from knowing that they once tutored the young Princess Zelda, it was apparently they who first told him of the mirror and its location. It could be inferred that he himself has had links to the Royal Family at some point: aside from his name bearing a strange resemblance to Rauru (which could also be said to be on account of his wise and elderly nature), the emblem of the Triforce is visible on the front of his clothing.
