Rassroen

Rassroen is a fictional planet located in the Andromeda galaxy. It is known for its unique atmospheric composition, which allows for vibrant, bioluminescent flora to thrive across its surface. The planet experiences a dual-sun system, resulting in extended periods of twilight and a complex ecosystem adapted to fluctuating light levels.

The dominant sentient species on Rassroen are the Lumina, a silicon-based lifeform with crystalline exoskeletons. The Lumina communicate through a combination of light pulses and resonant frequencies. Their society is organized into communal enclaves, each focused on the preservation of specific bioluminescent species. They possess advanced knowledge of bio-engineering and have developed symbiotic relationships with many of the planet's native organisms.

Rassroen's economy is based on the cultivation and trade of rare bioluminescent spores, which are highly sought after for their medicinal and energy-producing properties. The planet has a relatively stable climate, though occasional extreme atmospheric disturbances can occur, causing widespread luminescent displays. Exploration of Rassroen is heavily regulated by the Lumina to protect its delicate ecosystem.
