Zeridian

Zeridian is a fictional planet located in the Andromeda galaxy. It is known for its unusual crystalline flora and fauna, which are bioluminescent and exhibit a unique form of slow, rhythmic movement. The planet's atmosphere is rich in argon and neon, giving its skies a perpetual twilight hue. The dominant lifeforms are the Lumina, sentient beings composed of silicate-based structures. They communicate through complex patterns of light emission and sonic vibrations.

The Lumina have developed a sophisticated understanding of their planet's geology and energy fields, utilizing the abundant geothermal activity for their societal needs. Their civilization is characterized by its deep connection to the natural world and a philosophy centered on harmony and interconnectedness. While not technologically advanced in the conventional sense, they possess an intricate mastery of bio-engineering and energy manipulation. Explorers from other star systems have noted the Lumina's peaceful disposition and their complex, yet subtle, social structures. The planet itself is geologically active, with periodic crystalline growth spurts and subterranean energy surges that shape its surface.
