"What better way is there? We only got where we were before the Fall by working together, and it's the only way we'll get back there. Yeah, sure, some of my neighbors are assholes, and I have to tithe nine-tenths of my production to the leaders, but it's a small sacrifice... I think."
While the apocalypse was an immensely destructive event, humanity did survive, and human nature is to band together in groups and try to survive as a community. It also has been a significant period of time, and real communities have sprung up all over Sokal and other more distant parts of the world. While these communities do attract the more peacefully minded, they have become favorite targets of roving Bandit groups.
When they meet in the Wastes only one of two things can happen. The Bandits will extract what they can from the community until it's bled dry and dies out — a fate that has happened all over Sokal — or the community can put up enough of a fight that the Bandits will decide it isn't worth it. Any community that has lasted more than a decade in Sokal has thus become sufficiently militarized or come up with some other means of defending themselves from the Bandit threat.
Every community, however, fears the sweeping threat of Raiders more than anything. While Bandits can be deterred or negotiated with in most cases, Raiders simply seek to destroy all in their path. They will wipe out entire communities for no reason other than the sheer joy of destruction.
The Bako Commonwealth
"I love the Commonwealth. It's nice, peaceful, safe, and everyone knows their place. Some people say I'm naive, but I've never known anything else."
Bako itself may be a haunted mess, but on the outskirts of it lives the largest community of Settlers in all of Sokal. Fenced off from Bako's dangers and with enough infrastructure of its own, the Commonwealth has flourished into one of Sokal's few proper civilizations.
Keepers
"What's old is new again...Hehe, get it?"
Keepers are those, often settlers, who work on finding, restoring, and keeping the old world working. They might focus on books, machines, items, or just random facts. They are essentially historians and antiquarians in the wastes, working to preserve and maybe someday resurrect the world before.
The Ojai Grahla
"Well, we ain't all free love and good vibes. Sometimes we gotta get our hands dirty. But if you wanna trade, welcome friend."
One of the few stable communities in the area. Ojai Grahla (called the OG by most) sits where a major crossroads between the major cities of old met. Before the Fall the land was remarkably fertile and verdant compared to it's surroundings, a condition that persists to this day, making it a viable center for agriculture and trade.
