Eridor

Eridor is a fictional Earth-like planet used as a setting in science fiction literature and interactive media. It orbits a sun-like star in a distant galactic frontier and is typically portrayed as habitable to humans, with a diverse biosphere and a complex human settlement history.

The planet features two major landmasses separated by a broad ocean, with temperate to subtropical climates across its coastlines. Mountain ranges run along the western fringe, while extensive river systems foster rich wetlands and fertile plains. Its atmosphere is breathable, and weather patterns favor biodiversity.

Eridor was first mapped by orbital scouts during the early spacefaring era and became an active colony world shortly thereafter. It evolved into a federated polity, combining orbital settlements with urban centers on the planet's continents. Local government incorporates planetary councils and corporate guilds that influence policy.

Economic activity centers on sustainable mining, agriculture, and ecotourism, alongside spaceport-oriented services. Eridor's culture blends maritime heritage with frontier pragmatism; common languages include the native Eridori tongue alongside colonial dialects. Education emphasizes environmental stewardship and frontier sciences.

In fiction, Eridor serves as a stage for diplomacy, exploration, and ecological storytelling. Notable fictional features include the Blue Spine mountain range and the Azure Lagoons, which appear in various novels and role-playing games.
