The world got their first taste of a supernatural experience in 1967 when zombies were attacking Seattle. This spawned an actual government responsive unit known as the Department for the Research and Apprehension of Paranormal Entities. Also known as DRAPE. This agency has been operating for the last 50 years or so to stop the supernatural element from ever seeing the light of day. While they work along side Hunters, they do not support them. After all, killing the creatures stops additional experimentation and possible military applications.
Hunters and creatures still operate in secret, though DRAPE does come along and clean up all their massive messes. After all, someone has to keep the general public from knowing what is happening around them. The mass panic could destroy the very fabric of life as we know it. So while hunters attempt to keep the creatures in check, DRAPE cleans the mess; thus leaving very little room to be an actual supernatural being. Staying hidden has never been more paramount to their survival.
Though there are those few that want to take over the earth in their own right. Destroy the humans or beat them into submission. Who knows who's going to win the war, it's really just a matter of time before someone starts to figure it all out. Isn't' it?
