In a society where conflict exists between Posthumanism and Transhumanism, where the Sol System was dying, humans have left behind their mortal forms for ones that can survive in this hostile, unwelcoming solar system. Neo Terrans—post-human beings with android shells and uploaded human minds—rule the Alpha Avior System in a stagnant, artificial society, heavily separated between might, wealth, and learning. Divided onto four planets and their moons, they remain surrounded by the rings of asteroids around their system, of which secret groups of Transhumans forming the True Terran Society gather and plot.
