Mesidir

Mesidir is a fictional planet located in the fictional Xylos System, approximately 700 light-years from Earth. The planet is characterized by its arid climate, with vast deserts dominating its surface. Sparse vegetation exists primarily in subterranean oases, sustained by underground water sources. The atmosphere is thin and primarily composed of nitrogen and argon, with trace amounts of oxygen.

The dominant sentient species on Mesidir are the K'tharr, a silicon-based lifeform adapted to the planet's harsh conditions. They are known for their resilience and their ability to subsist on minimal resources. The K'tharr society is structured around nomadic tribes, each with their own traditions and territories within the desert. Their technology is focused on survival, including advanced water purification and energy generation systems.

Mesidir's geological makeup is rich in exotic minerals, making it a target of interest for off-world mining operations. However, the extreme environmental challenges and the presence of the K'tharr have made large-scale colonization difficult. Exploration of Mesidir has been limited to automated probes and small, specialized research teams. The planet's unique ecosystem and the K'tharr's survival strategies continue to be subjects of scientific study.
