I wanted to keep most of the usual aeons the same, such as Ifrit, Shiva and Bahamut.
It just seemed right to have them keep their proper name.
However I didn't mind so much about renaming aeons that I hadn't seen before...

Valefor = Garnet. Cos I'd recently finished FFIX and wanted to name something after her

Ixion = Morpheus. Cos it sounds cooler.

Yojimbo = Yo!Jimbo. It's a bit funnier ^^

Didnt have the others...

Oh and I called Tidus, Xander...after me!
