I know that Kefka and Celes were infused with magic at some point in time before the start of the game, thus their magical abilities. Celes handled her magic infusions fine but Kefka finally went off the deep end from his.
I'm assuming that they enlisted in service for the Empire and then recieved their magic infusions along they way, similar to Cloud in FFVII. Is this true or did they recieve it when they were much much younger, perhaps when they were children? Celes mentions that Cid is like a grandfather to her and calls him such, but there is never any mention in the script that I can recall that would point to the fact that she grew up around him, only that she viewed him as a grandfatherly figure while she was working for the Empire. This would make sense as Cid would have probably looked over her during her magic infusion and thus some sort or nurturing relationship would have been born with Cid watching over her and her looking to Cid for support.
Anyways, thoughts?
