Johdyns

Johdyns are a fictional species originating from the planet Xylos in the Andromeda galaxy. They are a sentient, bipedal race known for their unique biological adaptation to extreme environments. Johdyns possess a silicon-based exoskeleton that provides exceptional resistance to radiation and high temperatures, allowing them to thrive in Xylos's harsh volcanic landscapes.

Physically, Johdyns typically stand around two meters tall with a broad, sturdy build. Their heads are characterized by a cluster of bioluminescent organs that serve as sensory arrays, detecting heat, seismic activity, and subtle atmospheric changes. They communicate through a complex series of infrasonic vibrations and pheromonal signals, which are difficult for other species to perceive or interpret.

The Johdyn society is communal and deeply connected to their planet's geological cycles. They have developed advanced geothermal energy harnessing technologies and possess a rich oral tradition that recounts the formation of Xylos and their own evolution. While generally peaceful and introspective, they are fiercely protective of their homeworld and its delicate ecosystem. Interstellar contact with the Johdyns is rare, as they prefer to remain isolated, focusing on the internal development of their civilization and their understanding of the cosmos through direct observation of stellar phenomena.
