Setarans were a type of sentient species characterized by their unique physical features, including domed heads with ridges, light-colored skin, deeply positioned eyes, and gills that stretched from their necks to their prominent cheekbones. Lacking a mouth, Setarans used telepathy to communicate with other sentient beings. They were particularly recognized for their skill in tracking using the Force. One example of a Setaran is Calar, who was connected to the Path of the Open Hand.
