Auru

Auru is a character from The Legend of Zelda: Twilight Princess. A member of the The Group, Auru and his companions aided Link during the Twili invasion of Hyrule. Auru is a senior, but still possesses the strength and guile that he did in his younger years.

Biography
Many years prior to the invasion, he was the tutor to the Royal Family, and ultimately Princess Zelda. However, as he started to age, he retired and kept his distance from Hyrule. However, when the Twilight began to descend, he sensed something was amiss and chose to return to aid however he could. He was one of the few people in the kingdom that knew the full history of the Royal Family and their never-ending struggle against the evil known as Ganondorf.

Auru helps Link by calling in an old debt. He gives Link a note for Fyer, who agrees to shoot Link to the closed-off Gerudo Desert with his cannon. During Link's assault on Hyrule Castle, Auru defeats several Lizalfoses with a bazooka-like weapon, likely using technology similar to that of Bombs.

Possible connection to Rauru
Auru shares some similarities with Rauru, the sage from The Legend of Zelda: Ocarina of Time. Their names are similar and their appearance is somewhat alike, although Auru is noticeably thinner than Rauru. Both have also aided the Royal Family and their messenger. It is possible that Auru may be a descendant of Rauru, but no conclusive information has been obtained.
