Triton

A proud race originating from the Elemental Plane of Water, brought to the Material Plane by an ancient being long forgotten by the mortals. They live somewhere deep below the oceans, in a location unknown to man.
The Tritons civilization, known as Thun'Zol can be found far below the The Haunted Isles, where they are ruled by their Kraken Overlord. They are tasked with guarding the seas, as well as to protect the Kraken's cavern, where a great mystery lies deep within. Even unknown to the Triton themselves.
