Qu

The Qu were an ancient, highly advanced and evil alien species that split humanity as it was known into various new species with varying levels of sapience and ability.

Biology
The Qu were four-winged insectoid creatures, bearing a slight resemblance to dragonflies, with a single tail-like tentacle for manipulating objects. Their heads bear two eye stalks, one protruding from each side, and they have two long mandibles. While their main torso appears about as big as a Human torso, their tentacle makes their full body length about twice that of Humans. Their life cycle involved an aquatic larval stage, although their lifespan is unknown. Other elements of their native environment and physiology, such as what gases they breathe, their native gravity, and their diet, are also unknown.

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 genetic and nanotech manipulations, they constantly improved themselves and remade the worlds they visited. They were most likely the ones who created Panderavis from Earth 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 was eventually 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 descendants of humanity.

Many millions of years later, the human descendants in the form of the Asteromorphs, the Terrestrials and the Subjects formed a vast empire spanning the Milky Way, united with other galaxies such as the Amphicephali's, and finally avenged their ancestors by subduing the Qu, possibly rendering the Qu extinct.
