Vaetus

Vaetus is a fictional planet located in the Cygnus Arm of the Milky Way galaxy. It is known for its unique ecosystem, characterized by a high concentration of bioluminescent flora and fauna. The planet's atmosphere is rich in nitrogen and oxygen, with trace amounts of methane, giving the sky a perpetual twilight hue. The dominant species on Vaetus are the Lumina, sentient beings whose translucent skin allows their internal organs to emit a soft, pulsating light. They have developed a symbiotic relationship with the planet's flora, utilizing the bioluminescent properties for communication and navigation.

The geography of Vaetus is diverse, featuring vast, glowing forests, crystalline caves, and shallow, luminescent seas. The planet experiences a mild climate year-round, with no significant seasonal variations. The Lumina have built their settlements within the giant, glowing trees, integrating their structures seamlessly with the natural environment. Their society is largely communal, with a strong emphasis on ecological balance and spiritual connection to their world.

Exploration of Vaetus has been limited due to its remote location and the Lumina's cautious approach to outsiders. However, initial scientific expeditions have revealed a complex and interconnected biosphere, where light plays a crucial role in every aspect of life. The planet's unique energy signatures have also attracted the attention of off-world research organizations, though any significant interaction remains in its early stages.
