Though your characters are free to roam the world—and I’ve made a big effort to make the PC races be non-specific to Western cultures—we’ll be starting off the campaign somewhere in Europe, specifically at Bad Aachen, a hot springs resort town-turned-Early Modern “Babylon North” near the border between what’s now Germany and Belgium.
That’s just an easy jumping-off point, though, and while there’s plenty of adventure hooks in the area, including the setting of the playtest adventure we’ll be trying for our first meetup, it’s not like your characters are chained up there. (At least not yet!)
Which is to say, if you folks feel eager to have your characters wander off to parts unknown? All the better… and I have some ideas about places where fruitful adventures might be had. (See A Little Weird World Geography for some hints about those locales.) Here’s some info about the general area.
