Scaven are very large manta-ray looking creatures that live in several different deserts around Celestia. They make helium within their bodies that they store in large bladders, these are used to increase their mobility by allowing them to skim over the surface of the desert while they are active. When they rest the burrow under the surface of the desert, covering themselves with sand.
Variations of the Scaven exist in Deserts.
Scaven are total omnivores. They are willing to eat anything to survive.
Scaven are loners. Adults meet exclusively to mate and then part again. The only time they are found in groups are children still with their mothers.
