Not much is known about the Merfolks at this time.
The common mistake
Most landfolk say merfolk for anything with scales, hair, and bad intentions. That’s lazy, and in Aetheris it gets people hurt. The beings usually meant by the term are not Nerali gone wrong, nor some misunderstood coastal tribe hiding from the world. They are a separate thing altogether, and the surface habit of conflating them with the Nerali has caused more than one frightened settlement to point blame in the wrong direction.`
