Kostaleets

Kostaleets is a fictional species originating from the planet Xylos in the Andromeda galaxy. They are characterized by their bioluminescent skin, which glows in various hues depending on their mood and the surrounding environment. This bioluminescence serves as a form of communication, with specific patterns and colors conveying complex emotions and information within their society.

Physically, Kostaleets are tall and slender, with long, prehensile limbs and large, multifaceted eyes that grant them exceptional vision in low-light conditions. Their diet consists primarily of Xylosian flora, which is rich in phosphorescent compounds, contributing to their natural luminescence.

The Kostaleets have a highly communal society, living in interconnected subterranean cities carved into the planet's crystalline structures. Their culture emphasizes harmony, cooperation, and a deep respect for nature. They possess an advanced understanding of bio-engineering and energy manipulation, which they use to sustain their civilization and interact with their ecosystem. Their social structure is meritocratic, with leadership roles assigned based on wisdom and contribution to the collective good. Interactions with other species are rare, as they prefer to remain isolated on Xylos, focusing on their own societal development and the preservation of their unique way of life.
