Carathumpian of Tethys
The outer most colonised dwarf planet.
The Eris colony is mostly made up of scientists and researchers, but a few hardened frontier-loving people have also made their home on this distant outpost of humanity.
The main spaceport is located in Aphelion, the arguably largest settlement on Eris. Aphelion is a large domed city with high docking towers, the city is also partly carved out in the ground. It is in Aphelion that what is passes as trade and entertainment is most available. Agenor, the second larges settlement is mostly an underground complex, visible on the surface only due to one docking tower and a small dome in the side of a cliff. There are several other smaller settlements and installations, but these are mostly automated, or crewed on rotation.
