Serizit

Serizit is a fictional planet within the Andromeda Galaxy, notable for its unique geological composition and a single, dominant indigenous species. The planet's surface is characterized by vast crystalline formations that emit a soft, bioluminescent glow, particularly during the planet's extended twilight periods. These crystals are believed to be a result of extreme geological pressures and the presence of exotic minerals found only on Serizit. The atmosphere is thin but breathable for its native lifeforms, with a composition rich in inert gases.

The dominant species on Serizit, known as the Lumina, are sentient beings whose physiology is deeply intertwined with the planet's crystalline structures. They are silicon-based lifeforms, appearing as semi-translucent figures that can absorb and refract light. The Lumina communicate through complex patterns of light emission and subtle vibrational frequencies, a language that has proven difficult for off-world observers to fully decipher. Their society is communal and deeply attuned to the natural cycles of Serizit, with no discernible hierarchical structure. Their primary activities revolve around the maintenance and cultivation of the crystalline landscapes, which they consider sacred. Contact with external civilizations has been minimal, and the Lumina generally maintain a passive, observational stance towards visitors.
