Description
A chevall is a creature which can change at will between two forms: an intelligent horse, and a powerful centaur.
Chevalls concern themselves with striving for the good of all horses. They often go about in horse form, checking on the welfare of horses in the service of humans, demi-humans and humanoids. If a chevall finds a horse which is unhappy with its lot it will not rest until it has freed the animal.
