Triton

Tritons guard the ocean depths, building small settlements beside deep trenches, portals to the elemental planes, and other dangerous spots far from the eyes of land-bound folk. Long-established guardians of the deep ocean floor, the noble tritons have gradually become increasingly active in the world above.
