The River of the Serpent is in central Nyissa, and empties into the Sea of Winds. Due to its sinuous nature and sluggish current, a ship can sail for three days before reaching the capital of Sthiss Tor. "The River of the Serpent had a hundred mouths, each creeping sluggishly through the jellied muck of the delta as if reluctant to join the boisterous waves of the sea" - Queen of Sorcery
