Evria

Evria is a fictional planet located in the fictional Andromeda Galaxy. It is known for its unique biosphere, characterized by luminescent flora and fauna that thrive in the planet's low-light conditions. The atmosphere of Evria is a mixture of nitrogen, oxygen, and trace amounts of an unknown gas that contributes to its distinctive atmospheric phenomena.

The dominant intelligent species on Evria are the Xylos, a bipedal race with crystalline exoskeletons that absorb and refract light, aiding in their camouflage and communication. The Xylos society is organized into decentralized, nomadic tribes, each with a deep spiritual connection to the planet's natural cycles. Their technology is bio-integrated, focusing on harnessing the planet's organic energy sources and manipulating its flora.

Evria's terrain consists of vast, phosphorescent forests, deep, shimmering caverns, and oceans of liquid methane. The planet experiences a long, dim twilight period and a short, intensely bright "aurora season" where its two small moons align, causing spectacular light displays. Scientific study of Evria has been limited due to its remote location and the Xylos' cautious approach to outsiders. Early observations suggest a complex ecosystem with intricate symbiotic relationships between species.
