Okay, so I've got two options, one of which is a bit out of pocket, but the system could handle it.
Terminus is the first one.
The second would be modern day, with magic. You'd be part of a group that's sent to investigate some strange reports in New England when you get caught up into things that are even more out of the ordinary than you expect. (This one borrows heavily from a not-very-popular video game, so if you recognize it, then best to skip this one.)
