Appearance
The Thrennari are large and muscular, without a traditional layer of skin to cover their muscle fibers. They have a singular eye, and a vertical mouth placed on the lower half of their large head, which has an arrow-like shape.
Biology
Due to their planets complete lack of psionic energy, Thrennarans have developed a complete lack of any ability to interact with psionic energy.
Their large singular eye for sight, combines with many small imperceptible sonar pores on their face and hands allows for incredible depth perception at close distances, although it becomes much less usable at a distance.
Society
The Thrennari are an extremely Xenophobic race, but their hatred and fear of other races is multiplied by tenfold when interacting with races that have learned the arts of psionics.
Thrennari society is punctuated with extremely tight familial bonds. Despite their short lifespans, a large majority of a Thrennan’s life is spent with their family.
