Velolk

Velolk is a fictional planet located in the Cygnus X-1 system. It is known for its unique bioluminescent flora and fauna that illuminate the planet's surface during its extended nights. The atmosphere of Velolk is rich in nitrogen and oxygen, with trace amounts of methane, which contributes to its peculiar greenish sky. The planet's gravity is approximately 0.8 Earth standard.

The dominant life forms on Velolk are silicon-based, a departure from the carbon-based life prevalent on Earth. These beings, often referred to as the "Silicates," have developed a complex societal structure and a rudimentary understanding of interdimensional physics. Their cities are carved into crystalline formations, blending seamlessly with the natural landscape.

Velolk's geography is characterized by vast, crystal deserts, deep subterranean oceans, and towering, iridescent mountain ranges. The planet experiences extreme temperature fluctuations between its day and night cycles, with daytime temperatures reaching scorching highs and nighttime temperatures plummeting to sub-zero levels. Water exists primarily in liquid form in subterranean reservoirs, shielded from the extreme surface conditions.

Exploration of Velolk has been limited due to the challenging environmental conditions and the elusive nature of its native inhabitants. However, initial findings suggest a rich ecosystem and potential for further scientific discovery. The planet remains a subject of interest for xenobiologists and astrophysicists alike.
