návtvníky

návtvníky are a fictional species native to the planet Xylos in the Andromeda galaxy. They are a silicon-based lifeform, characterized by their crystalline exoskeletons that shimmer with a spectrum of colors depending on their mood and ambient light. Their physiology is remarkably different from carbon-based life; they derive energy through a process of geothermic absorption and photosynthesis, drawing sustenance from the unique mineral composition of Xylos.

The average návtvník stands approximately two meters tall and possesses four prehensile limbs, each ending in three sharp, obsidian-like digits. Their heads are multifaceted, with numerous simple eyes that provide a panoramic view of their surroundings. They communicate through a complex series of resonating clicks and harmonic vibrations, which can be perceived by other návtvníky over considerable distances.

návtvníky are known for their highly communal societal structure. They live in vast underground crystalline cities, meticulously carved and grown over millennia. Their society is organized into guilds, each specializing in a particular craft or knowledge base, such as geology, energy manipulation, or crystal artistry. Individual návtvníky are not born but rather "grown" from specialized seed crystals nurtured within communal incubation chambers. Their lifespan is exceptionally long, often spanning several Xylosian centuries. While generally peaceful and introspective, they are fiercely protective of their homeworld and its unique ecosystems.
