Xirias

Xirias 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 luminescence and emits a low-frequency hum. The planet's surface is largely arid, with vast deserts of shimmering sand and scattered oases supporting sparse, hardy vegetation.

The atmosphere of Xirias is thin and primarily composed of nitrogen and argon, with trace amounts of an exotic gas that contributes to the sky's perpetual twilight. Two small moons orbit Xirias, casting shifting patterns of light and shadow across the landscape. The planet experiences extreme temperature fluctuations between day and night due to its slow rotation and lack of a significant magnetic field.

Life on Xirias is scarce and highly adapted to the harsh environment. The dominant life forms are silicon-based organisms, including crystalline flora and fauna that draw energy directly from geothermal vents and the planet's ambient radiation. These creatures exhibit a slow metabolism and often remain dormant for extended periods. No sentient civilization has been discovered on Xirias, though archaeological evidence suggests a past presence of advanced, though now extinct, beings. Their ruins, often found embedded within the crystal spires, hint at a sophisticated understanding of energy manipulation and crystal growth.
