The Zodine river drains through the interior of the United Free Nations, historically supplying fresh water to several member city-states. Its course runs past what was once the settlement of Donokasi and through the tributary branches where Erdel's dye industry processed jungle plants into textile pigments.
Erdel's processors discharged decades of unregulated effluent into the Zodine, completely poisoning it. Donokasi, dependent on Zodine water for drinking and farming, could no longer sustain its population and was evacuated. The ruins remain along the river's banks; the water remains undrinkable.
The Zodine crisis is the confederation's sharpest ongoing political wound. Alacayir and Kalemeydani have repeatedly demanded reparations from Erdel, whose delegates argue the dye trade's revenue funds the shared road network that benefits every member city. Periodic Federal Council resolutions to fund remediation and resettlement have not passed.
