I haven't got much in my head so far, but I have a few ideas.  A small, scrawny young man from Ergiland, a pure magic user who is questioning his faith and unsure of his abilities and his place in the world.  I don't think he would be an orphan.  Possibly the youngest in a family of powerful mages, of strong and stout Ergilanders, and thinking himself unfit to be a part of them, he journeys to the Academy to become a real sorcerer.

That's it so far.  I'd like to hear more about the magic system, about the difference between wizards and mages, and about what other religions there are.
