If it helps, the impression I've gotten from Iobaria is that it's the most "Irish/Scottish" region. The art in the section on human ethnicities in Inner Sea Races was the big kicker there.
That actually does help, thank you. I had been thinking they were more Russian/Slavic-inspired.
I'm really hoping we'll see some current day Azlant settlements/towns (cities?) in the upcoming Ruins of Azlant AP.
That'd be cool! I wasn't sure how much of the AP would tilt in the direction of currently-inhabited cities and Azlant-based nations versus how much would be dealing with ruins, dungeons, and aboleths.
