Qu

The Qu (pronounced: Koo) were an ancient, nomadic, highly advanced alien species that split Humanity as it was known into various new species with varying levels of sapience and ability.
The Qu were four-winged insectoid creatures, bearing a slight resemblance to dragonflies, with a single tail-like tentacle for grabbing and using objects. Their heads bore two eye stalks, one protruding from each side, and two long mandibles. While their main torso appears to be similar in size to a Human torso, their prehensile tentacle makes their full body length five or more times 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. It is likely that their known form is not the true appearance of the Qu, but rather the result of genetic alterations of their species at some point in the past, akin to the alterations that turned Humans and Martians into Star People.
