Dunwater River

The Dunwater River meanders its way into the Azure Sea. It is a broad, slow-moving body of water. choked with reeds and too shallow in many spots to allow boats other than rafts to traverse it.
The Dunwater 's nature makes it an ideal stalking ground for bandits. Outlaws and evil humanoids build temporary forts along the river, keeping a watch out for anyone trying to make their way along i ts length. Some gangs stretch chains across the water to impede the pat h of a boat or raft, leaving it vulnerable to an attack.
Somewhere along the river (accounts vary as to the exact location) stand the overgrown ruins of a tower that once housed an order of alchemists. The alchemists came to an explosive end when an experiment caused the tower's upper level to explode and several vats of chemical s to burst and Rood the tower's basement. The resulting mixture attained a vague sentience, transforming into a great number of oozes that now plague the river. The oozes encountered in the river have swimming speeds equal to their normal speeds and can breathe both air and water.
