Not necessarily… a few possibilities(some got here in this thread):
a) The sleepers. By some reason(be it a lab experiment, weird event or just getting into New England only now) they started now their lifes in the Cataclysm.
They won’t live long, probably.
b) The hunters. Ten years at the wild, hunting monsters to eat… they are self-sufficient and efficient in what they do. I just don’t know about their mental stability or trust in others.
c) The farmers. Valuable members of communities(because having enough to eat for months will take space and work) or lucky people in technological plants, they know everything about the wild plants in the region. Don’t leave much, since are not that good in fighting and are afraid of leaving the safety of their lifes. With good reason.
d) The lost minds. The mutations and cibernetics helped in survival, but the effects of each change plus no one to talk with… being alone… left only a memory of sanity. They can handle the Cataclysm, the question is… WHO can handle them? And what they will be once their minds find stability again?
e) The converted. They chose to fight in the winning side, and IT’S NOT THE HUMAN SIDE. And survived to keep doing it so. Their enemies? Take a guess…
f) The traders. Humans are great at adapting, and even with all the dangers, some managed to create communities. Communities need stuff. Then someone decided to help in the process…
Traders are survivors masters in bargain, speech and basically avoid bad situations for themselves and their cargo. They are very suspicious, but don’t use excessive force, since each bullet and arrow counts at the end of the day.
