Rygir

Rygir is a fictional planet located in the Andromeda Galaxy. It is known for its unique geological formations, characterized by towering crystal spires and vast underground cave systems. The planet's atmosphere is rich in methane, giving its skies a perpetual orange hue. Rygir's primary inhabitants are the Lumina, a sentient species that has adapted to the planet's low-light conditions. The Lumina are known for their bioluminescent properties and their advanced understanding of crystal manipulation, which they use for both construction and energy production.

The planet experiences extreme temperature fluctuations, with the surface reaching scorching temperatures during its dual-sun days and plummeting to frigid levels during its extended nights. This harsh environment has led to the evolution of a diverse, albeit sparse, ecosystem. Life on Rygir primarily exists in the subterranean cave networks, where geothermal vents provide warmth and stable conditions. Flora in these caves often exhibits bioluminescent qualities, mirroring the Lumina themselves.

Rygir's history is largely unrecorded, with the Lumina relying on oral traditions and crystalline memory storage. Early Lumina history suggests a period of nomadic existence, followed by the development of complex underground cities. The Lumina are a peaceful species, focused on scientific advancement and the harmonious integration of their society with Rygir's environment. Their interactions with off-world species are rare, due to the planet's remote location and Rygir's challenging atmospheric and climatic conditions.
