It’s a pointless question in so many ways, but my relentless pursuit of detail drives me to ask where exactly in middle Europe this campaign is taking place. It is self defeating to attempt to nail it to a specific place because the genuine detail can clog up the fiction of the game campaign.
However, I’m pretty sure it is in the east, perhaps North East of Prague and South East of Dresden. Somewhere in the Carpathians. Bohemia. Perhaps the closest place might be Liberec. Perhaps these photos are typical of the area.
If nothing else, I now know that the place for inspiration for terrain can be found in the Czech Republic.
