The Wisp is an atmospheric species from Hesperia. They are a mostly gaseous bag covered in a constantly shifting membrane that glow and appears to be on fire. Wisps can change their color to camouflage themselves among the rainbow clouds of their native world. Wisp underbellies have dozens of thin tendrils that are used to grasp objects. Some of these tendrils have additional glowing points that were historically used to deceive prey animals into coming closer.
Wisps use their internal gases to float and propel themselves. Though they have eyes around their circumference have very limited sight, and no sense of smell. The mouth is located at the center of the underside, hidden by the tendrils. Wisps average about half a meter in diameter, not counting the tendrils.
