Cardewn

Cardewn is a fictional planet located in the Andromeda Galaxy. It is known for its unique geological formations and a singular, large moon. The planet's surface is predominantly composed of crystalline structures that refract light, giving the atmosphere a shimmering, iridescent quality. This phenomenon is most pronounced during the planet's twin sunrise, when two stars on opposite sides of the horizon illuminate the landscape simultaneously.

The atmosphere of Cardewn is rich in a gas that, while breathable for native lifeforms, is highly corrosive to most known terrestrial materials. This has limited extensive exploration by off-world entities. The native flora consists of bioluminescent fungi and silicon-based plants that draw energy directly from the planet's crystalline bedrock.

Cardewn is home to a sentient species known as the Lumina. They are a non-corporeal lifeform that exists as a collective consciousness within the planet's electromagnetic field. The Lumina communicate through complex light patterns and are believed to have a deep, symbiotic relationship with the planet's unique ecosystem. Their existence is largely theoretical for external observers, as direct interaction is exceptionally difficult. Scientific interest in Cardewn primarily stems from the potential for understanding non-carbon-based life and the physics behind its crystalline geology.
