Rakuks

Rakuks are a fictional species originating from the planet Xylos in the Andromeda galaxy. They are known for their distinctive bioluminescent skin, which emits a soft blue-green light that intensifies when they experience strong emotions. Physically, rakuks are tall and slender, with elongated limbs and large, multifaceted eyes that are highly sensitive to light. Their bodies are covered in fine, iridescent scales that provide a protective layer and contribute to their shimmering appearance.

The rakuks have a highly advanced society, characterized by their intricate cities built from crystalline materials that refract and amplify their natural bioluminescence. Their culture places a strong emphasis on communal living and the sharing of knowledge, with a complex system of telepathic communication that supplements their spoken language. They are known for their peaceful nature and their deep understanding of astrophysics, having developed sophisticated methods for interstellar travel and observation. Their diet consists primarily of nutrient-rich algae cultivated in subterranean hydroponic farms. Rakuks have a lifespan typically exceeding 500 Earth years, during which they dedicate themselves to exploration, scientific advancement, and the preservation of Xylos's unique ecosystem.
