I like it, Pieh. I've introduced Faerie into my fantasy campaign and can use fae-created stuff for the PCs to find. I see the Fae as a dying race, and things that create more fae would be very useful to them.
Yeah, she does sound like a wild magic, chameleon mage that soaks up the magic around her and makes it hers, until the next bit of magic comes along. She would definitely be fae-touched pretty soon, much too interesting to leave alone!
