I was part of a post-alien invasion society. It was a sort of authoritarian village system run on the inside of a highschool in the middle of the country. I don’t think we were even allowed outside. Village gathering places were the gymnasium, cafeteria, assembly hall etc. The alien masters were never seen but gave orders through the class of human collaborators that oversaw the village and ensured productivity and adherence to rules; they were either thugs or insufferable bossy control freaks (one reminded me of the girl in charge of yearbook I had the misfortune of working with at T-School). All the villagers had a job to do, sometimes several, but instructions could come from the top at any time changing this or giving special assignments.
