Ten years ago, a summoner named Braska chose three guardian.One man from Zanarkand named Jecht, another a warrior monk named Auron, and the youngest an orphan named Leon.
The journey to Zanarkand was long and hard, and during that time a strong bond formed between the four.
Finally they arrived in Zanarkand to find the truth about the final battle and Jecht became the final aeon. Sin was killed and the calm started but the two guardians they choose a different path.
Auron left for Zanarkand to take of Tidus because of the promise he made to Jecht, and Leon changed his name and left to Besaid Island to look after Yuna for Braska.
No one in spira knew where they went to, while in Besaid Leon began a new life as Seth yuna's best friend.
