The Silika River (pronounced sill-EE-kah) is a major river in the Western Coast. The river begins in the Kheldezir Hills near Avaz before eventually flowing into the Ludo River.
Due both to the scale of their operations and new methods they have pioneered, the mines and refineries of the dwarven nation of Barat Tor produce large amounts of toxic waste as a byproduct. Slag is deposited back underground in vast caverns, while liquid waste is dumped into the Silika River. By doing so, the dwarves keep their operations running yet poison the river for those that live downstream. The town of Isto is now uninhabited as a result, as the waters they relied upon have become poisonous. The Torri have regularly butted heads with druids who have attempted to protect the river, thus far unsuccessfully. By the time the Silika joins the Ludo River the toxic runoff is usually diluted enough to not pose a significant issue to communities farther downstream.
