"Magic in its purest form... it's a manipulation of a force, allowing you to do some wonderful things. Travel, create, help. Here with or without magic... being able to help is based on what you want to do. You don't need magic to do it but if you learned it you could use it to help in many forms."

All entirely Belle's own choice. Though along with the mages here she'd have a friend with her.
