The Cthons were the name of a subhuman race which inhabited the underbelly of Coruscant. They were genetically albino, having lived for generations out of the sunlight. They were also genetically blind, with their eyes having been bred out because of their uselessness in the dark underground levels of the cityworld. In place of eyes, the Cthons had egg-shaped organs which moved constantly just below the skin which covered their eyesockets. This skin covering seemed to change color, as subdermal membranes moved and shifted. Those who reported on the existence of the Cthons were considered doubly lucky, because Cthons were incredibly strong and were known to cannibalistic.
