The Nosix are actually a splinter of the Twix, that goes back at least a hundred thousand years. Considerable interbreeding used to occur between the two races used to occur, though for the last several thousand years the Nosix had been thought to be extinct due to the events of the Fall of the League. Instead in recent years a former colony was discovered providing a new population of Nosix and many now explore the stars.
Much like the Twix, Nosix have head tails. However Nosix head tails are quite numerous. They also have small horns on their heads, and traditionally ritually tattoo and scar themselves.
