The Dnieper is a major river in Eastern Europe. It flows through Russia, Belarus, and the Ukraine before emptying into the Black Sea.
In Mount&Blade: With Fire and Sword, the Dnieper flows past several major fortresses and towns of the Cossack Hetmanate and the Crimean Khanate, including Chernigov, Kiev, Cherkassy, Sich, and Kyzykermen.
In real life, the line of the Dnieper would begin much further north through Smolensk, but the geography is changed in game.
