Vaelori

Vaelori is a fictional planet within the Andromeda galaxy, known for its unique bioluminescent flora and fauna. The planet orbits a binary star system, resulting in distinct diurnal cycles and a perpetual twilight in certain regions. Its atmosphere is rich in nitrogen and oxygen, with trace amounts of noble gases that contribute to the planet's vibrant auroras.

The dominant intelligent species on Vaelori are the Lumina, a sentient race characterized by their crystalline exoskeletons and their ability to manipulate ambient light. The Lumina have a sophisticated, albeit enigmatic, society that is deeply intertwined with the planet's natural rhythms. Their cities are often constructed from living, bioluminescent coral and integrated seamlessly into the natural landscape.

Vaelori's ecosystems are diverse, ranging from vast, glowing underground caverns to floating islands sustained by atmospheric currents. The planet is also home to a variety of exotic creatures, many of which possess their own bioluminescent properties, creating a dazzling spectacle during the planet's extended night cycles. Scientific expeditions have noted the planet's remarkable biodiversity and the complex interdependencies between its life forms. The Lumina are generally peaceful but have a policy of strict non-interference with off-world species, making direct diplomatic relations challenging.
