Dalmuo

Dalmuo 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 emits a soft, bioluminescent glow, illuminating the planet's surface even during its long periods of darkness.

The atmosphere of Dalmuo is primarily composed of nitrogen and argon, with trace amounts of methane. This composition results in a thin, breathable atmosphere for native life forms, though it is not suitable for human respiration without augmentation. The planet experiences extreme temperature fluctuations between its day and night cycles, with temperatures soaring during the day and plummeting to near-absolute zero during the night.

Life on Dalmuo has adapted to these harsh conditions. The dominant species are silicon-based organisms, known as the Xylos. They possess crystalline exoskeletons that protect them from the temperature extremes and the low atmospheric pressure. The Xylos are known for their telepathic abilities and their deep connection to the planet's crystalline structures, which they believe hold the collective consciousness of their ancestors.

Dalmuo's ecosystem is sparse, with only a few specialized flora and fauna surviving. The most notable flora are the 'glow mosses' that thrive in the perpetual twilight zones created by the crystal spires, and the fauna consists of small, rock-dwelling creatures that feed on these mosses. Exploratory missions from Earth have shown a keen interest in Dalmuo's unique mineral composition and the Xylos' advanced biological and psionic capabilities.
