thanks a lot ijimonji, but your answers make me think about a couple more questions.

- Why Sin keeps atacking towns, he was summoned to destroy bebelle but it keeps damaging everyone.is sin an aeon , or a yevon armor to live forever ?, what are the reason of yeavon to keep killing ?
- Why bevelle created that Yeavon teachng things like the "fobidden machina ", they were repent to destroy zanarkand , why use the name of the enemy yevon ?, I think is pretty funny to see how everyone is saying all the way to zanrkand "yevon this, yevon that" and when they get to yunalesca and she says "yu Yevon" they say, Who is that one ? Who is yu yevon ?.
- what is the main porpuse of faith dreaming a new zanarkand.

what a big story for a game, everytime I finish a FF it´s the same glorious thing.
