Can you shed a bit of light on how people are organized for living? The deadly fog background suggests that most people are grouped up in relatively safe enclaves and that those will be defended at all cost since being homeless is, or was, effectively a death sentence. Is the rest of the land mostly just deserted or have people had enough time to form new established routes between places like markets etc? My current interpretation is that mostly you find no people at all, unless you find an enclave where there would be quite a lot of people, living quite cramped.
I ran our test session in the cliché roadside tavern that was just there for no good reason at all. That's fine for toying with the rules. But since it was such a success we will continue playing this as a campaign and so it'd be good to have some idea of what to expect in the published books.
