There is a forest that likes to pretend that it's ordinary. It isn't, it's quite bizarre. Every night, in fact, zombies and other horrible monsters swarm this place, looking for people to kill. Not that they've found anyone, the forest itself is quite empty of residents. But they search anyway, during the night, shambling and groaning and occasionally leaving body parts lying around. Those disappear pretty quickly, but it still happens. Then the day comes, and they depart to who knows where, swearing (if mindless monsters could think, or in fact swear to anything in particular) that they'l be back the next night. Repeat ad nauseum.
It's currently in the day portion of this cycle of directionless attempts at violence. Maybe this day will be different from all of the others.
But then, probably not, it's a very boring island without anyone here.
