Kyrion

Kyrion is a fictional terrestrial planet that appears in science fiction settings within the imagined Lumen Expanse. It is described as the third planet orbiting a binary star system, with a year length close to 1.2 Earth years. The planet's biomes range from temperate forests and highland wetlands to extensive coastal archipelagos, creating diverse ecosystems.

Geography and climate: About 62 percent of Kyrion's surface is ocean. Its coastlines are irregular, forming numerous bays and lagoons that affect regional climate patterns. The atmosphere is broadly similar to Earth's, allowing breathable air for humans and many other species. Precipitation is common along western margins due to oceanic currents, with aridity increasing inland.

Biota and inhabitants: Kyrion hosts indigenous Kyrionite flora and fauna alongside human and hybrid colonists. The planet's sentient population, typically called Kyrions, is depicted as maritime-oriented, with regional communities that maintain strong ties to rivers and coasts. Several language groups are described, including a Kyrionic language family and a common trade language.

Governance and economy: Kyrion is governed as the Kyrion Republic, a constitutional federation within the broader Lumen Confederation. The economy combines sustainable fisheries, mineral extraction, and research-focused industry. Ecotourism and conservation programs target fragile coastal ecosystems and biodiversity.

History and legacy: In lore, exploration and colonization begin in the mid-22nd century, followed by integration into interstellar governance. Kyrion appears in novels, games, and media associated with the franchise, where it is used to explore themes of environmental stewardship, diplomacy, and frontier settlement.
