The Fyernor are a sentient serpentine species. They are a nomadic species, living in patriarchal tribes of up to fifteen individuals. They have little civilization and no permanent structures. The Fyernor were venomous, preferring to paralyze their prey before eating them live. They are covered in jagged scales, and are often patterned in stripes or spots. They have milky-white translucent eyelids, through which they were able to see; this adaption protected their eyes from sand frequently whipped up by strong winds on their desert moon.
