Etaarir Hegemony: Dozens of worlds are ruled by the Etaarir, who control their space with powerful warships and soul crushing fear. Inhabitants of these worlds must obey the Etaarir and their strict laws, or become fodder for their genetipools where unspeakable experiments are conducted in a quest for the race to better control their constantly mutating genetic code. Dozens of races live under their claws, little better than slaves.
Galactic Confederacy: Despite it's impressive name, the GalCon does not span the entire Milky Way galaxy but only a fraction of it. Numerous aliens have combined together for financial stability and military protection since many of these races home planets or colonies are disturbingly close to the Etaarir Hegemony.
There are many humans in the GalCon, as well as Wrin, Falimore, Benzo, Corburu, Ghilabos, Axaousar, and Xur.
Ylir Empire:
The Ylir are even more xenophobic than the Etaarir. Their "empire"
consists of a dense sector of resource rich worlds that provide the race
with plenty of resources. Many of these worlds, it is believed, had
been inhabited, but due to Ylir hatred of all things not Ylir, but now
only the Ylir remain.
