You could include a sub-genre of horror/rural legends like: Sleepy Hollow, Rural Ghost Stories, Children of the Corn, etc. That would be pretty cool.
Like a part of the Farmpunk world from the Wrong side of the Tracks? That could get creepy. I also see a Paladin-esque class, or maybe a Hobo-esque class that roams the boarder-tracks Keeping the Creepy on the Creepy side, and the Non-Creepy on the Non-Creepy side.
Barbarian-esque Loggers... this sort of setting would be fantastic.
It would be based on DnD 3.5, yes?
Or it's own system?
