This is one of a handful of worlds we’ve come across where there doesn’t seem to be any kind of Native American influence in North America, and Asian traders from the South Pacific stopped and settled instead. Likewise, Europe has yet to colonize to the West Coast, although we’ve heard rumors of white men to the East, so it’s coming soon.
The result is a relatively unspoiled region that’s fun to visit… provided you avoid the natives. They aren’t terribly friendly.
