Anchimayen
The Anchimayen is a mythical creature in Mapuche mythology. Anchimayens are described as little creatures that take the form of small children, and can transform into flying fireballs that emit bright light. They are the servants of a kalku.
According to some sources, the goddess was originally conceived of as the moon goddess, married to the sun, but later developed into a fuego fatuo type being that frightens and unhorses travelers.
Anchimayens are sometimes confused with Kueyen, because she also produces a bright light.
