Across fog-shrouded coasts or endless ocean swells, an ominous drone sounded on a conch shell chills the blood of all who hear it. This is the sound of the sahuagin hunting horn-a call to raid and battle. Coastal settlers refer to sahuagin as "sea devils," for sahuagin have no compassion in them, slaughtering the crews of ships and decimating coastal villages.
