Daryth

Daryth is a fictional terrestrial planet used in speculative fiction and role-playing contexts. In in-universe lore, it belongs to the Caelus star system and orbits a mid-sized K-type star, completing a planetary year of approximately 365.6 days. The name is said to derive from the Darythi language, meaning “bright valley,” a reference to sunlit lowlands described in early maps.

Geography and geology: Daryth measures about 12,000 kilometers in diameter with a surface gravity near 0.95 g. The planet features three major continents connected by extensive river networks, including the large Lyris Basin. The terrain ranges from lowland floodplains to highlands such as the Sigha uplands in the southern hemisphere, where tectonic activity periodically reshapes coastlines and floodplains.

Climate and biosphere: The climate varies from tropical in the equatorial belt to temperate and subpolar zones toward the poles. The global average temperature is around 14 degrees Celsius. Daryth supports diverse biomes, including broadleaf forests, savannas, and alpine grasslands, with a suite of endemic flora and fauna described in in-universe field guides and compendia.

Society and culture: The planet is inhabited by humans and several near-human communities collectively referred to as the Darythians. Political organization is a federal republic known as the Assembly of Daryth, with major urban centers such as the capital city Hara and the coastal hub Veyla. The economy blends agriculture, mineral mining, and light sector manufacturing, underpinned by a developing research and technology sector.

Technology and space exploration: Daryth hosts a modest space program focused on satellite networks, atmospheric research, and fusion power development. Orbital stations and a central cargo port enable intersystem trade, while in-fiction narratives explore ecological ethics, governance, and the challenges of colonization.
