Auron

Auron is a playable character in Final Fantasy X. He is a former warrior monk of Yevon, guardian of High Summoner Braska, and is Tidus's caretaker. He is, in many ways, the mentor of the Final Fantasy X main party as party members will often come to him for advice or ask for his permission.
Auron's complex and mysterious past, revealed in pieces during the game, directly ties into the stories of Braska and Tidus's father Jecht, and helps set the stage for the game's events. In the English localization of Final Fantasy X, Auron is pronounced [ˈɔː.ɹən] (or-run).
