The Sun tribe is a group of stranded xenophobic creatures who live in a secluded village deep in the Sahara desert. The moniker "Sun tribe" comes from local legends which depict them as hideous monsters that feed on lost children, although scholars today generally hold such tales as pure myth. The large, vein-like protuberances which cover the skin are part of an intricate organ system designed to capture water from the air. They tend to shun outsiders, and have very limited contact with humans. It has been theorized that they are extraterrestrial.
