Also commonly called “sea devils” and the terror of many coastal settlements, sahuagin are found in the world’s oceans. They are also a constant threat for sailors, along with pirates, for they will board passing vessels to drag crew overboard to feed to their pet sharks. They do this kind of thing supposedly whenever a ship passes through sahuagin territory. Which is in the ocean. And unmarked. Areas known to be prowled by sahuagin are avoided by ships, but those areas are also mutable.
