This name generator will give you 10 names which will generally fit the tritons of the Dungeons & Dragons universe.
Tritons are aquatic humanoids with webbed feet, webbed hands, blue skins, and colorful hair. They're the protectors of not just the ocean depths, but, if you asked them, of the entire world.
While there is some arrogance at play, much of which comes from living such isolated lives, they are genuinely protective of those in need, and of the entire world. Their arrogant and sometimes self-righteous behavior can be off putting to some, but the tritons mean well. They're simply not used to the way life works outside of their deep sea homes.
Triton names are melodic, but do have some harsher tones as well. Female names always end in -yn, and male names always end in -s. Their surnames always end in -ath, and tend to be much longer and complex than their personal names. Male names also seem to always be 2 syllables long, while female names can be 2 to 3 syllables long.
