Firmor

Firmor is a fictional planet located in the Andromeda galaxy. It is known for its unusual atmospheric composition, which gives its sky a perpetual twilight hue of deep purple and orange. The planet's surface is characterized by vast, crystalline deserts and towering, bioluminescent fungi that dominate the landscape. These fungi are the primary source of light and sustenance for the planet's indigenous lifeforms.

The dominant sentient species on Firmor are the Lumina. They are a silicon-based lifeform with translucent bodies that absorb and re-emit light. The Lumina communicate through complex patterns of bioluminescence and subtle sonic vibrations. Their society is deeply intertwined with the planet's fungal ecosystems, relying on them for shelter, food, and spiritual practices.

Firmor's climate is generally stable, with moderate temperatures and low humidity. However, the planet experiences occasional "light storms," where the bioluminescent fungi intensify their glow, creating dazzling but disorienting visual displays. These storms are believed to be a form of planetary communication or energy release.

Exploration of Firmor by off-world civilizations has been limited due to the planet's remote location and the challenges posed by its unique environment. However, preliminary studies suggest the presence of rare mineral deposits and unusual energy signatures, making it a subject of interest for xenobiologists and resource prospectors. The Lumina have shown little interest in external contact, preferring to maintain their reclusive existence in harmony with their radiant world.
