While there's plenty information on cities and even some towns or single homesteads in official sources, I haven't been able to find much info about villages.
Medieval ones are rather spacious settlements surrounded by farming fields, orchards, pastures and whatever else. However, given the dangers of the Old World, I'd imagine villages here to be really dense and cramped, surrounded by a palisade to protect its inhabitants from beastmen, mutants and everything else that roams local wilderness.
So, is there some official answer in WFRP sources about how villages look?
