Shadowmen
this was the common name used to describe the race of beings that inhabited the planet Nivek. The Shadowmen were a race of rail-thin, insectile humanoids who resembled walking skeletons. They evolved unique adaptations to living in the near-total darkness of Nivek's environment, and had incredibly sensitive night-vision. As a people, the Shadowmen were known as skilled hunters and trackers. During the height of the Clone Wars, the Shadowmen sided with the Separatists, and allowed a weapons facility to be erected on the surface of Nivek.
