Surwiths

Surwiths are a fictional species that inhabit the planet Xylos. They are known for their bioluminescent skin, which they use for communication and navigation in their perpetually twilight environment. Surwiths are a sentient species with a complex social structure, typically organized into large family clans. Their diet consists primarily of fungi and subterranean roots, which they cultivate in elaborate underground farms.

Physically, Surwiths are bipedal with elongated limbs and large, multi-faceted eyes. Their skin color ranges from deep violet to vibrant blue, with intricate patterns of light that shift and pulse to convey emotions and ideas. They possess a mild telepathic ability, allowing for a degree of empathic connection within their clans.

The Surwith civilization has developed advanced bio-engineering techniques, allowing them to manipulate organic matter for tools, shelter, and even transportation. They are generally a peaceful species, prioritizing harmony with their environment and each other. Their technology is largely organic in nature, eschewing conventional metallurgy and electronics. Interaction with off-world species is rare, and their culture remains largely enigmatic to outsiders.
