In my world, magic isn't dangerous so long as you use it properly, but there are sorts that can be dangerous. My country was steeped in Free magic at one time, and that kind of magic, necromancers still use. It is dangerous and unpredictable, and can transform its user into the sort of dark thing you might call a demon. But a long time ago, magic was bound to the Charter by... I suppose by the sorts of things they would call Gods, in this world. Charter magic is safe to use, and orderly. That's the sort I'm trained in.
