and the location of the Zamoyos
The Zamoyos is a river in Sothoryos which flows into the Summer Sea at a large delta. It is known for its green waters, quicksands, and rotting, half-submerged trees. The river contains crocodiles, schools of carnivorous fish, and worms which lay eggs in swimmers.
Now in ruins, Zamettar was a colony established by the Old Empire of Ghis at the mouth of the Zamoyos. Upriver are the ancient cyclopean ruins of Yeen.
After fleeing Essos, some of the Rhoynar briefly settled along the Zamoyos.
