Mordenkainen Presents: Monsters of the Multiverse

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 sea floor to the ocean’s surface.

Tritons have webbed hands and feet, small fins on their calves, and coloration that favors blues and greens.

Volo's Guide to Monsters

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.
