Tooting my own horn..A few years ago I ran a D&D game in a setting called
Northern Crown A alternate history kind of mish mash of the Tales of Alvin Maker novels and steampunk.
Now I'm worked on a Pathfinder version of it. The
Northern Crown for Pathfinder Kickstarter went live today.
It should be pretty easy to update for 5th edition if you're using that rules set.
