I'd leave his age the same, myself. You've kind of got the "untested young commander vs. a somewhat older and more experienced team" thing going. A well-used trope, maybe, but a good one. Lots of comic/dramatic room to work with, so to speak.

Perhaps I will :)

Also Jim, you should probably know that Elemental Knights have the ability to control all four elements, and are not restricted to one. Of course, that doesn't mean you're not allowed to specialize (you can still keep your character fire-focused if you want). I'm just saying that Anna can learn other elements if she wishes.
