Zyns have evolved on ocean moon of Ctalul, the single major moon of gas giant Darstan which orbits the orange dwarf Verrstbirt. Ctalul was once an icy planet with an unstable orbit until it was captured by its parent gravity and when the gas giant has migrated in habitable zone, the world has become molten.
Ctalul orbits its parent in 38.793 earth days and has a local solar day of 35h53m39s.36. Ctalulian atmosphere is thiner than earth (0.99 atm) and it composed of nitrogen, oxygen,argon and water vapours. The climate of this world is eternal spring-like and is a low gravity (0.25374 g). Being a waterworld without any solid surface, Ctalul has abundant floating vegetation which function as a food and shelter for native flying fauna.
Zyns are an aquatic race resembling earth cephalopods. Zyns have twelve tentacles which all can be used to manipulate objects. Zyns have the best eyesight of all sentient species, they are capable to see visible spectrum to humans and different frequencies of radio waves,infrared spectrum,ultraviolet rays and X-rays and because of this they are formidable enemies able to shoot their weapons with a very high precision.
Unlike their earth counterparts, Zyns have a very centralized nervous system. Zyns are able to generate and sustain electric fields used to attack prey or to defend against predators. The electric fields can be also used to generate bioluminescence which can be used as form of long range communication.
Society and government
Zyn are an hive minded species, the queens aren't leaders, they are just the female reproductive system of the hive. Barons, fertile males, form the governing bodies and male reproduvtive system of Zyns. Workers are infertile females who do all manual labour,scientific research and engineering for the hive. Soldiers are infertile males which form the military of Zyns, they are strongest of all Zyns and come in two flavours, aquatic and aerial.
Zyn workers have symbotic relationship with plants from Cenpolla genus. The plants offer room for metalurgy and a liquid that strenghten the electric field generated by Zyns, while the Zyns offer the plants the minerals from metalurgy waste and help them by making pollination of their flowers.
Zyns curently suffer from a mysterious disease that severly reduce the number of workers born. Since Zyn robotics aren't as efficient as those of other species, the only logical solution to compesate for the small number of workers was enslavement of other sentient species.
Zyns implement control chips in their slaves in order to keep them in line, these chips are known to cause severe headaches when a wearer display some rebellious feeling, the migraines can lead to mental illness and suicide. Slaves are given the right to keep their native technology.
