Grennig River
The pure waters of the Grennig River tumble out of the Rheuthengage Mountains only to be befouled almost immediately by the ore smelting in Caladon. As they flow southward, they pick up the stench and waste from the vast herds of cattle raised on the Rheuthen Basin. Finally, as they enter the Sea of Storms they pass Grennig, one of Tariens most populous cities. By this point the water is almost black, though a few streaks of irradiance seem to lighten its color.
