The furthest inhabited point from the sun in the Centauri system is the Nordic federation of tribes. They eek out a meager living on frozen moons and underpowered space habitats. Their main source of economy comes from raiding other worlds when their orbits align. Most interesting about these people is that their homes orbit the ghost of a planet.
Unlike Oceanus or Germania, the planet of Fenrir (or what we can only assume was a planet) has collapsed into a black hole. The moons an stations of the Nordic federation eerily orbit around seemingly nothing at all.
There are many theories as to how Fenrir came to be in it’s present state ranging from the delusional (the Nordic worlds are actually held in orbit by a psychic alien at the center) to the more widely accepted ideas (Fenrir was artificially transformed into a black hole by the long gone Earth Empire)
