The Qu were a sapient species and the first extraterrestrial civilization that made contact to the posthumans called the Star People.
Biology
The Qu were four-winged insectoid creatures with a single tentacle for manipulating objects.
Their life cycle involved an aquatic larval stage.
History
At the time of the first contact between Qu and Star People, the Qu were almost a billion years old, constantly travelling the galaxy from one spiral arm to the next, in giant, epoch-spanning mass-migrations. As masters of genetical and nanotechnological manipulations, they constantly improved themselves and remade the worlds they visited. They were most likely the ones who created Panderavis from earhly Therizinosaurs.
Their religion demanded them to remake the universe as they saw fit and they saw themselves as gods. This dogma was rooted in what had been a benevolent attempt to protect the race from its own power, but is now blindly followed by them without any question.
Humanity was only a small obstacle to them. The Qu were offended that there was another species that remade the worlds they visited, and they remade the star people into many different creatures.
One day, the Qu left the spiral arm that was once populated by the star people, leaving behind hundreds of worlds inhabited by the remade decendants of humanity.
