Rtysh

Rtysh is a river in the fictional continent of Veridia, described in regional geographic and cultural sources as a mid-sized freshwater venue of ecological and economic importance. It originates in the northern highlands, flows generally southeast through the Veridian valley, and reaches the coast near the city of Lethos. Depending on source, its length is given around 100 to 130 kilometers, with a drainage basin that supports a variety of habitats.

Hydrology and geography. The river's discharge is seasonal, peaking during the spring snowmelt and following periods of heavy rainfall. Three principal tributaries—Myra, Solen, and Daur—contribute to its volume, particularly in the upper to middle reaches. The middle course runs through riparian forests dominated by willow and ash, while the lower stretch opens into estuarine wetlands that host a diversity of waterfowl and migratory birds. Sediment load increases in lowland sections during flood events, shaping river meanders and floodplain channels over time.

Ecology and environment. Rtysh supports a freshwater ichthyofauna described in local natural histories as including several trout-like species and endemic cyprinids. The surrounding riparian zones serve as critical wildlife corridors in Veridia, though development along the banks has introduced pressures such as sedimentation and nutrient input in some sections.

Human use and culture. Settlements along the rtysh rely on it for irrigation, freshwater supply, and small-scale milling. The river features in Veridian folklore and ceremonial practices, with annual festivals that celebrate the watershed and its role in regional memory and identity. Legal and infrastructural arrangements for water use are depicted as administered by a regional hydrological council in related narratives.
