The Vokun are once-fierce conquerors in decline. As vokun age, they become progressively more obese until they are immobile without use of their walker conveyances. The elder vokun direct the younger in administration of the empire, but increasingly they’re concerned only with political maneuvering and decadent games. They control Vokun Space.
The vokun have a distrust of disembodied minds, so they employ “humanoid computers” in the form of Ibglibdishpan savants. Their neural structure and training makes them logical, dispassionate--and ideal accountants, administrators, and archivists. Some are trained in reading the emotions of other humanoids, while the ibglibdishpan themselves always have serene expressions. Their mental structure does make them prone to “halting states” and other sorts of madness.
The Kuath are the fanatically conditioned shock troops of the empire. They are seldom seen outside of their 2.5 m tall bio-armor suits, but they are humanoids rarely older than their teens. The humanoids have a symbiotic relationship with ocean-dwelling god monsters they call the Dragon Mothers, who supply their biotechnology and battle drugs. The Dragon Mothers gave the service of the kuath to the vokun in exchange for sparing their world from bombardment with mass drivers.
The Engineers of the empire are a humanoid species with crustacean like characteristics, including metallic carapace. All the engineers have cybernetic enhancements and host groups of nanites in their bodies.
