Vastinema

Vastinema is a fictional planet located in the Andromeda galaxy. It is characterized by its unique geological formations and diverse, albeit limited, ecosystem. The planet's surface is dominated by vast, crystalline plains that reflect the light of its twin suns, giving it a shimmering, almost ethereal appearance. These plains are interspersed with towering, obsidian-like spires that reach high into the thin atmosphere. The planet experiences extreme temperature fluctuations between its long days and nights, with the crystalline plains expanding and contracting audibly.

The ecosystem of Vastinema is sparse and highly adapted to the harsh conditions. The dominant life forms are silicon-based, appearing as slow-moving, rock-like creatures that absorb energy directly from the twin suns and the planet's geothermal activity. Plant life, if it can be called that, consists of metallic growths that extract minerals from the soil. Water is extremely rare, existing primarily in the form of subsurface ice or as vapor during brief, intense atmospheric events. The planet's atmosphere is primarily composed of nitrogen and argon, with trace amounts of methane. No indigenous sentient species have been discovered on Vastinema. Its primary scientific interest lies in its unique geological composition and the extreme resilience of its silicon-based life.
