It's complicated. But there are monsters called the Creatures of Grimm. As far as I know they've been around forever but they've gotten worse as time goes by. Outside of four kingdoms and a few other scattered villages or cities they pretty much have run over the world.

It's just kind of how things are where I'm from.
