Triton

Tritons resemble aquatic elves in their upper half, but their lower halves are more fish-like, with scaly legs and webbed feet. They favor tridents over other weapons. Tritons are of the outsider type but native to the Material Plane, though they are thought to originate from the Elemental Plane of Water. Tritons are able to magically summon water elementals and other creatures of the sea to come to their aid.
