Atlanteans are the inhabitants of all city-states of Atlantis.
Atlanteans were forced to adapt to life under the ocean surface when their continent sank. They used sorcery and science to allow for underwater breathing.
Over millennia, inhabitants of each city-state evolved further, with many of them evolving features similar to those of aquatic animals such as fish, cetaceans and squid. Atlanteans refer to themselves as "water-breathers". The variety of the people of Atlantis led to racial tensions between "skin and scales" and "flesh and fins" in the form of the purists, led by Ocean-Master. They considered themselves pure descendants of the original Atlanteans: fully human, without visible fish features. They hoped to cleanse Poseidonis of its diversity.
