Vissian
The Vissians are a highly advanced (by human standards in the 2150s) humanoid species native to the planet Vissia in the Vissia system.
Physiology
Vissians are distinguishable by crescent-shaped, segmented ridges circling the eye at the temple. Unusually the Vissians had three genders: the third gender, the cogenitors, made up only 3% of the population and were treated as inferior, existing only for facilitating reproduction between males and females.
Vissians are able to read, learn, and retain large amounts of new information much more quickly and easily than Humans.
History and Technology
The Vissians claimed to have developed Warp drive more than a millennium before Earth. In the 2150s, Vissian space travel utilized superior warp core and sensory technology compared with Humans. They were also using photonic weapons, rechargeable with sarium microcells.
The Vissians claimed to have developed a polymer composed of over 200 natural elements. At that time Humans were only aware of 92.
At least one ship type was capable of withstanding temperatures higher than 1100 degrees to withstand exploration within a stellar corona. Their stratopods were able to pass through the hydrogen layer of a hypergiant. The Vissians offered to modify NX-01 Enterprise's sensors to detect nucleosynthesis.
Culture and Philosophy
Vissian appreciation of food is based on aroma rather than taste. Of Human foods tried, they tend to like varieties of cheese.
Vissians are more forward and liberal than Humans are with regards to copulating. They prefer to have sexual intercourse first before continuing a relationship.
Vissians tended not to travel far, believing that there was sufficient exploration close to their homeworld: this is the reason why they had not expanded particularly far from their homeworld, despite possessing warp drive far longer than humans had. Their primary goal was to meet new species. They were willing to share their technology with the Enterprise. (ENT: "Cogenitor")
