Theralia

Theralia is a fictional planet located in the fictional Xylos system, approximately 40 light-years from Earth. It is described as a terrestrial world with a nitrogen-oxygen atmosphere, supporting a diverse range of flora and fauna. The planet's surface is characterized by vast oceans, dense forests, and mountain ranges, with a climate that varies from temperate to tropical. Theralia is known for its vibrant ecosystem, including bioluminescent plants and creatures adapted to low-light conditions.

The dominant intelligent species on Theralia are the Lumina, a sentient race with a silicon-based biology. The Lumina are known for their advanced understanding of bio-engineering and their harmonious relationship with their environment. Their society is structured around communal living and a deep respect for nature. They possess a unique form of telepathic communication, allowing for intricate and nuanced interactions.

Theralia has been a subject of interest for intergalactic explorers and xenobiologists due to its unique biological properties and the advanced civilization of the Lumina. Several expeditions have been documented, aiming to study the planet's biodiversity and to establish peaceful contact with its inhabitants. These interactions have been largely cooperative, fostering a mutual exchange of knowledge and cultural understanding. The Lumina have shared insights into sustainable living and advanced biological sciences, while off-world visitors have provided information on astrophysics and different societal models.
