Amorion

Amorion is a fictional terrestrial planet used as a setting in science fiction literature, media franchises, and tabletop role-playing games. In most canons, it orbits a sunlike star in the Amorion system and is described as Earth-sized with diverse biomes and a long history of exploration.

The planet features several continents separated by wide temperate and tropical seas. Its climate is mediated by a large ocean, producing mild to warm temperatures and distinct wet and dry seasons. The atmosphere is typically described as nitrogen-oxygen with trace argon, supporting a breathable air and moderate surface pressure.

Geologically, Amorion is considered relatively young compared with Earth, with active tectonics, mountain belts, volcanic arcs, and deep ocean basins. The surface hosts forests, savannas, mangroves, and alpine regions; notable geographic features include the Tiara Trench and the Shard Mountain range.

In-universe narratives describe early robotic surveys, followed by human colonization and later cultural exchange with resident populations and visiting fleets. The planet has been a focal point for discussions about resource use, environmental stewardship, and planetary governance within its fictional setting.

Amorion appears in multiple works and game lines, with varying depictions of its ecology and civilizations. Some portrayals emphasize scientific plausibility, while others emphasize space opera diplomacy and frontier exploration.
