Triton and Mer

The Triton and Mer are cousin races. Both resemble humans from the waist up, with fish-like tails from the waist down. The only true difference is that the Mer are capable of shedding these fish-like tails, and growing human like legs, distinguished from humans only by remaining fish scales upon those legs and gills upon their necks. The Mer can breath air and water and are the Ocean races only connection to the land races, acting as traders and occasionally diplomats to coastal nations. The Triton and Mer live in two kingdoms, Pelagia, the coastal Priest-Kings who are the land dwellers only point of contact with the Ocean dwellers, and Oceania, a shattered kingdom that lives on only through refugees and its remaining Pearl Kings

The Atlantians are, as described by the Mer, a cross between a frog, a fish and a human who rule the Deep Oceans. They fight a war with an unknown race that has lasted hundreds of years, after a fallen star shattered the Basalt City of Atlantis. The Atlantians also destroyed the kingdom of Oceania in their conquest of the Deep Oceans, driving them out of the waves and to the shore kingdom of Pelagia.
