Kelpies
Kelpies are a type of Scottish fairy horse and this breed is theorized to have escaped their fae masters to live in the wild. They are very loving and prefer to be in a herd lest they die from loneliness. Unfixed stallions tend to be aggressive and have been known to fight over mares, people, and territory. Both stallions and mares have long manes and tails, are typically naturally colored, and have feathered fur on their hooves. Height does not differ much between sexes, with mares typically being between 14 and 16 hh and stallions between 15 and 18 hh. They are a dead species.
