In Patricia Briggs - Mercy Thompson series - the supernatural world has always
been there but has been staying hidden but now because there are a LOT of humans
it's a lot harder. So the Fae came out first and now most of them live on reservations
of some type. The werewolves are also coming out because, I believe, they were
going to be outed if they didn't come out on their own.
They have a far harder time of it than the Fae because they are big and a rogue one
can be very dangerous.
The vampires don't dare come out - werewolves look downright cudley next to a vampire.
You could look at the supernatural world as the shadow plane of this world.
