Ok, i know that at least one other person here has played it(if memory serves me right) so there's one thing I hafta ask that has been bugging me for the past 6 months

Raven's heart is a blastia core right? At the end of the game, all blastia in the world were removed or lost power (can't remember, 6 months was too long) so anyways how did Raven survive that I mean he still appeared in the epiloge
