Esrolan

Esrolan is a fictional planet that appears in science fiction and worldbuilding communities as a shared setting for stories and games. It is typically described as an Earth-like world with temperate biomes, multiple continents, and a breathable atmosphere, orbiting a yellow-orange star. Its climate features distinct seasons and a moderate axial tilt, supporting forests, highlands, and coastal ecosystems.

In its common lore, Esrolan was settled in antiquity by agrarian and seafaring cultures. The planet has seen several political arrangements, including coastal republics and inland confederations, often centered on river valleys and port cities. A recurring feature is the Oracle Cities, ancient ruins that are said to preserve astronomical and ecological knowledge.

Economy and technology vary by region but usually blend agriculture with early industrial capabilities and burgeoning spaceflight infrastructure. Trade routes along rivers and sea lanes connect inland settlements to orbital outposts and spaceports.

Culture and society are diverse, with languages, customs, and belief systems reflecting the planet's geographic breadth. Environmental stewardship is a common theme in modern interpretations, with many works portraying a society grappling with resource management and sustainable development.

In fictional media, Esrolan serves as a flexible backdrop rather than a fixed canon, allowing authors to adapt its geography, history, and culture to fit different narratives. Some interpretations treat it as a standalone world, while others place it within a wider stellar setting.
