I have an interesting addition. It's not as good as -3- but it's something.
1000 YEARS ago. A type of magic was discovered. At first this magic was allowed freely. Until a public descision made it illegal. This type of magic called Cursed Magic has been lost through the ages. As the only magic that could make people go oof, everyone deemed it dangerous. What other things is it capable of? No one knows. Cursed magic users have been banished from the world and sent to a different realm where magic does not exist. Rendering them powerless. Nothing else is known of this magic. If it is used by anyone they will also be banished.
It's not too interesting but I gotta make something real quick.
