Yilneh

They live in the T'Vienor Expanse, they don't tend to get along well with the Vienaran Sect, and they exist alongside the Vrixid and the Tiwethi.
They are telepathic and will only eat what they have killed themselves to avoid the flavor of old fear making the meat bad. Which came from a random generator but I like it because most telepath races tend to be vegetarian and yet these guys are like naw imma eat it anyway but do it humanely.
The Yilneh have four eyes on their head which stick out a bit (not on stalks just protruding a bit) and blue skin that is fairly tough.
They are capable of space travel and definitely warp drive but the Vienaran Sect goes to great lengths to prevent them from making use of it.
Living within T'Vienor is odd enough, but their particular moon has some unusual characteristics in terms of gravitational anomalies and the sheer amount of telepathy enhancing crystalline rock structures around mean that while they are the only fully telepathic race, they are used to contact from the other species. They travel back and forth between the various moons as do the other two.
Intermarriage is allowed, but interbreeding does not work and produces sterile offspring. They share no common evolutionary ancestor with the other two species.
They are the dominant species on their world, presiding somewhat over the other two. None of them seem to mind this as they have come to largely equitable arrangements.
In general, culturally they are diplomatic and great farmers and hunters. Their medical sciences are very advanced due to a rich herbal wildlife available. Their ships tend to be fairly small and compact, simply for travel between moons.
