[@WindsOfFate] Try to think about the interest of your character. It's perfectly okay to have a character that uses magic styles under all of the Aeons. Remember, try not to think of Aeons as a magic style, but rather a classification of use. Aeons are the simply put the root of all magic styles and therefore all magic are just branches from them - the more "perfect" a certain magic style gets, the closer it is to becoming an Aeon. Therefore, don't be afraid to just make a characters magic however you want. Discussion on whether it fits into the story is moot since the Aeon system is very, very flexible. The only thing that will necessitate discussion is the power level of your characters magic relative to their rank - it's perfectly reasonable to have a master-ranked mage with super complex and powerful magic, but the same can't be said for a journeyman.
