FFX-3 Chat

I'm not sure I quite understand what point you were making there. Are you wondering if every aeon was created in a situation where there was one particular summoner who would benefit from its power more than others?

The Ultimania Omega for FFX isn't clear on that point. I do recall that it tells us some of the present aeons existed before Sin and some came after -- i.e., there were a few already in Zanarkand, which Bevelle then divided up among the temples for the purpose of the pilgrimage and then there were others made later when new temples were built. I would guess that the post-Sin fayth would be Yevon devotees who wanted to contribute, but whether they were close to any particular summoner, I would doubt -- otherwise they would have presumably been used as a final aeon at Bevelle's behest, in which case those fayth would no longer exist.
