The killers, mostly serial murderers, or victims of terrible tragedy, are pulled out of reality by it and convinced or forced to do its bidding. In order to maintain its existence, the Entity requires sacrifices, and demands that they hunt and kill the survivors so it can feed off their hope and steal a piece of their souls upon death. In order to continue this hunt, The Entity blocks off the Gateways of death and puts the dead into a dreamlike state that leads the survivors back to The Entity's world to get hunted again.
