(I see the desert has no one...screw it.)
The Marauders
Location: Eastern Desert (Farther within than the position of where the other city-state's location could be)
Military: (Exceptionally High) All members of the civilization carry their own weapons, and are highly trained in combat. Their weapons are of moderate quality, but some families have discovered a few working relics from before the war that are used for extreme situations.
Government: Bordering total anarchy. Structure only really exists from the Guardian Organization, which only protects the settlement from highly dangerous creatures mutated by radiation that come from beyond the farthest east.
Peoples: Humans (and Khajiit) whose bunker collapsed long ago, but within a region of the desert that possessed a lower radiation level than the norm of the time, allowing them to survive.
Laws: Mild to Nonexistent, as prejudices and violent tendencies have been eroded by their situation to nil, causing the people to have little to no animosity towards another.
Religion: While the religion followed is entirely up to the individual, people near unilaterally follow the teachings of "the Foundation of Society", which has one teaching:
(The creatures) are our greatest foe. We must not go back to hiding in fear that plagued our early days. No one else will protect us. We must stand up for ourselves. We are to be the shield, in the hopes that civilization shall rise again. Failure is not an option.
