There's more than one dome. Quite a few infact. (I'm bad at conveying the size of the thing, but there's at least a million people on board, so the ship is probably several kilometers long).
So a bit more worked out:
The passengers( Not a completly correct name, since there are lower class people on board to, choved into modules and other crappy habitation thingies)
Holdings: 3 biodomes
Population: Low-Medium
Tech: Well-equiped
Resources: Decent
Other:
- Relies on external power supply, as the domes solar pannels no longer provide enough solar energy this far from the sun
- This faction contains most of the better of people of this ship, and as such they want to have a descent amount of luxury
Problems expected:
-Power cuts
-People being unhappy
-Possible food shortage after expansion
-Being overrun
Stowaways()
Holdings: Several Habitation modules, one farm module
Population: High
Tech: Non-existent
Resources: Barely, though they can probably salvage quite a bit from the modules
Other:
-When the security forces retreated, the people surged up and united themselves. They managed to liberate one farm and quite a lot of terrain, thanks to their ability to move through the maintenance corridors.
Problems expected:
-Breakdown of modules
-Power cuts (The modules have only emergency generators, and none in decent shape)
Crewmen
Holdings: -Crew quarters ship part. (State of the art, and highly defensible) rather small though
Population: average
Tech: Mostly weaponry
Resources: none
Other: Militaristic, and depends on raids of other parts of the ship to supply themselves
Problems expected:
-Food and resource shortages
Space dogs
Holdings: -Docking bay delta, several small ships
Population: Small
Tech: Good
Weaponry: Decent
Resources: Decent
Other: All trained pilots, and most of their gear is loaded in the ships and mobile. This allows them to quickly move between ship parts.
-They posses decent supply stocks, but no means of resupplying if they run out.
Problems expected:
-Fuel shortage, being overrun
-No real assests: No farms, just a small dock. Need to rely trade or raiding.
The Power alliance
Holdings: Secundary Fusion generator (Blast doors and such, highly defensible)
Population: Few
Tech: Exceptional
Weaponry: Non existent
Resources: Few
Other: Scientists and technicians operating the generator locked themselves in when problems arose. Now their food supply is running out, so they'll have to open the doors once more
Problems:
-Military threat
-Food shortage
