Rauaks

Rauaks are a fictional species native to the planet Xylos in the Andromeda galaxy. They are a sentient, silicon-based lifeform characterized by their crystalline exoskeletons and bioluminescent internal organs. Rauaks communicate through a complex series of light pulses and subtle sonic vibrations emitted from their bodies. They possess a hive-like social structure, with individuals serving specific roles within their colonies, such as workers, defenders, and thinkers.

Physically, adult Rauaks typically stand between 1.5 and 2 meters tall. Their bodies are segmented, allowing for a surprising degree of flexibility despite their rigid outer shells. They have multiple limbs, usually four to six, which they use for locomotion and manipulation. Their sensory organs are integrated into their crystalline structure, allowing them to perceive a wide spectrum of light and vibrational frequencies. Rauaks are known for their advanced understanding of geology and crystal manipulation, which they use to construct their subterranean habitats and develop sophisticated tools. Their diet consists of mineral deposits and specific forms of Xylosian flora. Reproduction is a communal process involving the merging of genetic material from several individuals to form a new crystalline matrix, from which young Rauaks slowly develop. Their lifespan is estimated to be several centuries.
