Nethirians

Nethirians are a fictional sapient species originating from the planet Xylos. They are characterized by their bioluminescent skin, which can change color and pattern to convey emotion and communicate complex ideas. This ability is central to their social structure and interpersonal interactions. Nethirians have a naturally high resistance to radiation and can survive in environments that would be lethal to most other known lifeforms.

Physically, Nethirians are tall and slender, with elongated limbs and large, multifaceted eyes that allow them to perceive a wider spectrum of light than humans. They possess a dual circulatory system, one for oxygen transport and another for nutrient distribution, which contributes to their resilience. Their diet consists primarily of crystalline growths found deep within Xylos's crust, which they process through a unique digestive system.

Nethirian society is highly communal, with individuals prioritizing the collective good over personal gain. Their technology is deeply integrated with biological engineering, focusing on symbiotic relationships with their environment rather than exploitation. They have developed advanced forms of bio-luminescent communication and energy generation. Nethirians are known for their philosophical outlook, often contemplating the interconnectedness of all life and the flow of cosmic energies. They have a long lifespan, often exceeding several centuries, and their culture emphasizes wisdom and experience.
