Letzea

Letzea is a fictional terrestrial planet commonly featured in science fiction settings. In most continuities it orbits a mid-type star in the Letzean system, several light-years from Earth. The planet is described as having a temperate to warm climate, extensive coastlines, and a mix of large continents and archipelagos.

Geography comprises three major landmasses—Aurora, Nivea, and Solis—separated by broad seas and linked by archipelago chains. The climate ranges from tropical coastal zones to temperate interiors, with strong monsoon systems near the equator and seasonal polar cycles.

Letzea's ecosystems are noted for bioluminescent flora, expansive mangrove-like wetlands, and a diverse megafauna adapted to island and coastal habitats. The planet hosts a shallow biosphere that interacts with human activity in agriculture, logging, and mining.

In fiction, Letzea is home to several polities often organized as federations of city-states. A recurring theme is the Letzean Compact, a treaty that established environmental stewardship, resource sharing, and a framework for cooperative offworld exploration.

Societies on Letzea combine maritime traditions with advanced science. The primary offworld language is Letzean, and the economy emphasizes mining, aquaculture, energy production, and orbital services. Researchers study climate dynamics, ecology, and terraforming methods.

Letzea appears across novels, games, and media as a setting for ecological and geopolitical narratives, illustrating frontier governance and the challenges of sustaining planetary systems.
