The Spacers are the last sapient descendants of the Star People who escaped the oppression of Qu. Living in giant habitats carved out of the interiors of comets and asteroids, the Spacers are heavily modified as a result of living in zero gravity. Their limbs and hands have become long and spindly, and their circulatory systems are pressurized so to prevent clotting. To move about through the vacuum they expel air through a modified anus. After the departure of the Qu, they began to build more hollow habitats around interstellar systems because they could no longer re-colonize a terrestrial planet--their species was adapted to zero gravity. These creatures eventually evolved into the Asteromorphs.
