Trcaia

Trcaia is a fictional planet within the Andromeda galaxy. It is known for its distinctive crystalline flora that absorbs and re-emits ambient light, creating a constantly shifting, iridescent landscape. The planet's atmosphere is rich in nitrogen and argon, with trace amounts of an unknown gas that scientists believe contributes to the unique bioluminescent properties of its native fauna.

The dominant intelligent species on Trcaia, the Lumina, are a silicon-based lifeform. They possess a complex social structure centered around communal energy harvesting from the crystalline forests. Their communication is a combination of sonic frequencies and light patterns emitted from specialized organs. Lumina society is highly technologically advanced, particularly in the fields of energy manipulation and bio-engineering.

Trcaia orbits a binary star system, resulting in distinct day and night cycles that are further influenced by the planet's axial tilt. This creates varied climates across its surface, from frigid polar regions dominated by ice crystals to equatorial zones where the crystalline forests grow most intensely. The planet's geological makeup is characterized by large, geologically stable plateaus and deep, mineral-rich canyons. Research indicates that Trcaia has a relatively young geological history, with significant volcanic activity in its past shaping its current topography.
