This roleplay is set during the pilgrimage of Yuna and her guardians. The only difference being there are only minor canons allowed.
This is about your characters travels during the time of Sin.

Perhaps your character is a summoner or guardian that Yuna and co, had not met? Are you a blitzball player trying to get into the big league? Perhaps your a crusader traveling to the Mushroom Rock Road?

Whatever you wish - within reason - This is your story.
