Aery Evenfall is part of the Fright-Mares line, which featured characters that were half monster and half centaur/horse. These dolls are smaller (about 15.24cm) and have a distinct four-legged body sculpt, making them stand out in a collection. The Fright-Mares line, along with the rest of G1 Monster High, is retired, which provides a baseline of collectible value.
