The place that is modeled after is a real place called Centralia in Pennsylvania. It’s a town largely knocked down due to unstable grounds due to the coal fire that has been going on underground for years. Because of this toxic gasses and smoke bellow out of people’s basements and house foundations. There are several venting pipes as well. If I recall there is maybe a dozen hold out residents left in the town and possibly a handful of vampires or something. I got bored watching a documentary about it.
