Hey, wanna ask something since I can't really see it from your post.

How is the setting of this? As in, what time period? What kind of technology is already around? Are there electric lights? Vehicles? You mentioned magic-powered technology, but is this more like steampunk magitek, or pre-industrial, or?

I'm thinking of making a student who's a musician, and might be able to do magic with music. I suppose that makes her element air?
