Aryuihl inhabit the planet Humans call ‘Mars.’ They live underground, near to the core of the planet. Their cities surround the planet’s center. In the past, the Aryuihl had outposts on the surface, but the atmosphere and storms of their planet grew in successions, and it no longer was a rational use of resources.

Aryuihl are generally lithe, and their height is typically short. The outermost layer of an Aryuihl’s form radiates a neon green light. The majority of their layers of flesh are translucent, but the innermost layers obscure their internal organs and structure. Antennae sprout from the top of their heads.
