>>612707The biggest risks would be
-People from the city (we are less than 20 miles away from a large city, and 50 miles away from London). Although most of them would starve anyway, there could be a few gangs of 10-20 people roaming about.
-Other factions springing up in the community. This isn't likely, as as I have said, most would die or join our community.
-Huge hoards of mad max lord humongous raiders, which are very unlikely.
Realisticlly, life would return to anglo saxon times, people farming and living off the land. Bandits and raiders would only ambush travellers on roads, they wouldn't attack well defended villages and settlements.
