Triton

Originally from the Elemental Plane of Water, many tritons entered the Material Plane centuries ago in response to the growing threat of evil elementals. Those tritons spread across the worlds’ oceans, protecting the surface from terrors in the deep. Over time, triton have extended their stewardship over the seafloor to the ocean’s surface. Tritons have webbed hands and feet, small fins on their calves, gills on their necks, and coloration that favors blues and greens. 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. Nowadays finding a civilization of tritons living on a series of incredibly large boats and rafts sailing together as one across the ocean’s surface isn’t an unnatural sight. Tritons have a very stoic and poised personality, seeing themselves are protectors and destroyers of evil. Tritons are incredibly skilled sailors.
