Predatory & piscine best describes the sahuagin, a cross between human & fish is another, and temperament of a shark. They worship shark gods, and a common god is Sekolah. Only their females are worthy to become clerics of Sekolah, and hold tremendous authority in their communities.
They dwell in the deepest parts of the oceans, rising to attack other species, especially Elves (in particular Sea Elves). When carrying out an attack they use a sea horn to call others to battle, especially on land. Each raid, and community even, is generally led by a warlord with four arms instead of two, and as a race they are driven into a frenzy when there is the smell of blood.
