Kyelni

Kyelni is a fictional planet located in the Andromeda Galaxy. It is known for its unique geological formations, characterized by towering crystal spires that reach into the atmosphere. These spires are composed of a mineral unknown on Earth, which exhibits a faint bioluminescence during the planet's long nights. The atmosphere of Kyelni is rich in nitrogen and oxygen, with trace amounts of inert gases, making it breathable for many known lifeforms, though long-term exposure without proper adaptation is not recommended.

The planet's surface is largely arid, with vast deserts punctuated by deep canyons. However, scattered throughout these deserts are oases fed by underground rivers. These oases support a surprisingly diverse ecosystem, with hardy, silicon-based plant life and small, multi-limbed creatures that have adapted to the harsh conditions. The dominant lifeform on Kyelni, the Kylari, are sentient beings who have developed a sophisticated society centered around the preservation of their crystalline environment. They are known for their advanced understanding of crystallography and their ability to harness the energy emitted by the planet's crystal spires. Their cities are built into the sides of the canyons, blending seamlessly with the natural landscape.
