The Cosmic Empire, so called because they believe themselves to be the proper ruler of the Galaxy, conquers their neighbors and promptly vassalizes willing nations. Led by race of tentacled arthropods from the planet Odesion, which orbits the star Lacitra, they had a tense but ultimately friendly rivalry with the Terran Solidarity, who proved military might against them again and again, gaining their respect.

The Cosmic Empire consists of tentacled, squid or octopus-like rulers, and a more crab-like subservient people who provide labor and muscle, though their previously conquered territories have a wide variety of races.
