River Qaro (pronounced KAH-roh) is a major river in Ishtar. Together with River Qes, these twin rivers are the primary geographical distinguishing features of the region, critical not only in an ecological sense but also culturally, historically, and religiously.
Both rivers begin in the east, fed by rainfall and melting snowpack from the mountains of the Zakros, joined by smaller tributaries as they flow west. For most of their courses, both rivers are quite wide and flow languidly across the landscape, turning into an expansive marshland near the coast. River Qaro is the northern of the two rivers, flowing through eastern Thadria before reaching the Chaska Sea. Many smaller tributaries join the river on its route.
The lands surrounding the river are highly productive, and many cities have grown up along its banks.
