Larua

Larua is a fictional planet located in the Cygnus Arm of the Milky Way galaxy. It is primarily known for its unique bioluminescent flora and fauna, which illuminate the planet's surface during its extended periods of twilight. The planet's atmosphere is rich in oxygen, with trace amounts of inert gases, making it breathable for many known life forms, though certain atmospheric compounds can cause mild disorientation in non-native species.

The dominant life form on Larua is the Lumina, a sentient species characterized by their crystalline exoskeletons and their ability to communicate through complex light patterns. The Lumina have developed a sophisticated, albeit non-technological, society focused on ecological harmony and the study of stellar phenomena. Their settlements are often found integrated into the natural landscape, utilizing the planet's geological formations and bioluminescent plants for shelter and energy.

Larua's geological makeup is largely volcanic, with vast plains of obsidian and mountains of silicate rock. Several large, shallow oceans cover a significant portion of the planet's surface, teeming with phosphorescent marine life. The planet experiences a relatively stable climate, with mild temperatures year-round, though seasonal variations in bioluminescence intensity are observed. Exploration of Larua has been limited due to its remote location and the Lumina's preference for isolation, though scientific outposts have been established in orbit for observational purposes.
