Tilaén

Tilaén is a fictional planet located in the Andromeda Galaxy. It is known for its unique geological formations and diverse, albeit sparsely populated, ecosystem. The planet's surface is characterized by vast, crystalline deserts that shimmer with an iridescent light under its twin suns. Towering rock spires, carved by centuries of atmospheric erosion, punctuate the landscape, often housing small, bioluminescent flora.

The atmosphere of Tilaén is thin and composed primarily of nitrogen and argon, with trace amounts of oxygen. This makes it largely inhospitable to most known life forms without specialized protective gear. The temperature fluctuates dramatically between day and night due to the lack of a significant atmospheric blanket.

Life on Tilaén, while rare, has adapted to these harsh conditions. The dominant life forms are silicon-based organisms, often resembling mineral growths or slow-moving crystalline entities. These organisms derive energy from geothermal vents and the unique radiation emitted by the planet's core. No sentient civilization has been discovered on Tilaén, though evidence suggests a primitive, microbial stage of life may exist beneath the surface. Exploration of Tilaén has been limited due to its remoteness and the challenges posed by its environment.
