Changeling

A changeling, also historically referred to as an auf or oaf, is a human-like creature found in folklore and folk religion throughout Europe. A changeling was believed to be a fairy that had been left in place of a human stolen by the fairies.

Changelings are largely equine in appearance but possess insect-like characteristics. They have black, carapace-like, furless exteriors, webbed manes and tails, blue non-reflective eyes (unlike their queen's), fangs, bent horns, jagged ears, insect-like wings, and holes in their legs
