Taevastian

Taevastian is a fictional planet within the Andromeda Galaxy, notable for its unique atmospheric composition and the enigmatic civilization that calls it home. The planet is characterized by its exceptionally dense atmosphere, rich in argon and trace amounts of an unknown noble gas, which refracts light in peculiar ways, often creating spectacular auroral displays visible even during daylight. Surface temperatures are generally mild, with large oceanic regions interspersed with continents featuring unusual crystalline flora.

The dominant sentient species, known as the Lumina, are bioluminescent beings with a complex societal structure centered around communal energy harvesting and philosophical contemplation. They possess a non-corporeal aspect to their existence, able to project consciousness and interact with their environment through psionic means, though they also maintain physical forms. Their technology is advanced but largely organic in nature, grown rather than manufactured, and integrated seamlessly with their planet's ecosystem. Taevastian's Lumina are known for their peaceful disposition and their profound understanding of cosmic energies, which they believe connects all life in the universe. Limited contact has been established with off-world species, primarily for the exchange of knowledge and philosophical discourse.
