RTF is a global modification that replaces all towns in the game.

For the mages from the Academy, I think we could make Void Mages, Liches, and Necromancers. Besides, I don't think mages would look very good with the Elementals.

Let the Elementals have Djinns instead. By the way, who will be created based on the Lich model? (if you are going to remove the magical Elementals)
