Crana

Crana is a fictional planet located in the fictional Orion Arm of the Milky Way galaxy. It is primarily known for its unusual atmospheric composition, which gives its skies a distinct emerald hue. The planet's surface is characterized by vast, crystalline forests and deep, geothermally active canyons. Its primary inhabitants, the Crani, are a sentient species with a silicon-based biology, allowing them to thrive in the planet's unique environmental conditions. The Crani are known for their intricate social structures and their advanced understanding of geology and planetary engineering.

The economy of Crana is heavily reliant on the extraction and refinement of rare minerals found deep within its crust. These minerals are crucial for various interstellar technologies. The Crani have developed a sophisticated system of subterranean transit and resource management. While generally reclusive, the Crani have engaged in limited trade with select off-world civilizations, primarily for advanced energy sources and specialized biological components not found on their own world. Their culture emphasizes patience, resilience, and a deep connection to their planet. Research into Crana's unique geological formations and the Crani's biological adaptations is ongoing by various xeno-biological and geological organizations.
