Asteromorph

The Asteromorphs were a posthuman species that evolved from the Spacers.

After the spacers joined all of their arks into one giant world built from gravity-free bubbles, their bodies became even more spindly and single digits evolved into whole appendages, but none of those were used for locomotion because their specialized sphincters propelled them through their worlds.

Most of all, their brains evolved. Free from the burden of weight and gravity, their brains expanded beyond the limits of terrestrial organisms and they started to think in concepts totally alien to their posthuman relatives and human ancestors, which led to them developing philosophy and science far superior to that of their ancestors.

The Asteromorphs expanded by building smaller sub-arks and colonized stellar systems to build a new empire of man, but this time they didn't colonize any planets and only lingered in the outer realms of star systems, silently watching their primitive relatives.

When the Second Empire of Man, founded by the Satyriacs and the Killer Folk and by now completely aware of their history with the Qu, encountered the Asteromorphs, they feared the worst. But after the Asteromorphs turned out to not be interested in the Second Empire, the were accepted as incomprehensible, omnipotent forces of nature and left alone.
