Arien

The Arien species, known scientifically as "Homo Lariena", are a species of sapients who are a distant descendant of the Ancestors. As such, they share many similarities with the Common Human (Homo Sapiens), such as two manipulables, two movementaples, an upright posture and similar sensory organs. Unlike the Common Human, they have a distinct red skin pigment, wider eyes, an inverted olfactory organ and an overall shorter height. These changes are the result of thousands of years of natural selection through various generations of Ancestors on the Arien's homeworld of Jula'va, where the conditions on the surface are not suitable for long-term exposed habitation.

Jula'va itself is a desert world 7,103 kilometers in diameter and a gravitational acceleration of 0.45g. Its atmosphere was 40% oxygen, 52% carbon dioxide, and 8% trace gasses including neon, water vapor and carbon monoxide. Jula'va's star was a B-type blue star, which produced excess red light. When a population of Ancestors settled on Jula'va in the distant past, its is likely they only lived in domes or deep beneath the ground.
