Rotbavs

Rotbavs are a fictional species originating from the planet Xylos in the K'tharr Nebula. They are known for their unique biological adaptation, possessing a crystalline exoskeleton that provides both protection and a means of communication through bioluminescent patterns. These patterns change color and intensity to convey emotions, warnings, and social status.

Physically, Rotbavs are bipedal, standing approximately 1.8 meters tall. They have four limbs, with the upper two ending in dexterous, multi-jointed appendages. Their sensory organs are concentrated in a head-like structure featuring compound eyes that can perceive a wider spectrum of light than humans. Their diet consists primarily of mineral-rich subterranean flora, which contributes to the growth and maintenance of their crystalline shells.

Rotbav society is highly communal, with individuals often working in tandem to achieve common goals. They have developed a sophisticated understanding of Xylos's geological formations, which they utilize for shelter and resource extraction. Their technology is deeply intertwined with their biology, focusing on bio-engineering and crystal manipulation. They have a deep respect for their environment and a long-standing tradition of ecological preservation. While generally peaceful, Rotbavs are fiercely protective of their home world and their way of life.
