Rivermouth is a dense city built in northeast Rivermouth Marsh. Its buildings are stone and pine wood, built close together in the manner reminiscent of a maze. It is the Byasvonde capital city, small but strong. The city is also rumored to be the headquarters of Thauver, but that is mere speculation, and most think that Thauver has to central base.
The buildings all have two floors, each with an egde of shingles that reach out over the streets, blocking the sunlight and strengthening the dank roads below. The buildings are all stone and pine, built close in the manner of a maze.
Rivermouth is the capital city for the Empire Byasvonde. The former capital was New Alexandria, but Alexandria has become a factionally neutral city, a sort of safe haven. Rivermouth is strictly Imperial.
