Rhea

One of the frontiers of human civilization, Rhea is only just large enough for a colony, and primarily composed of water, ice, and rock. The only thing the moon has to offer the rest of the system is Helium-3 deposits, and some small mineral mining operations.
Rhea’s several small underground habitats provide all the living space required for its population, mostly comprised of miners and workers in the Helium-3 refineries. Most of their food must be imported from Titan, increasing costs, and mineral and Helium-3 exports do not bring much money into the local economy.
The fact that anyone lives on Rhea at all is a testament to human stubbornness and determination. Humanity will try to live and thrive just about anywhere.
