A Sha-Dar is a fictional type of person in David Eddings' series The Belgariad and The Malloreon. A Sha-Dar is sometimes called the Clan Chief of the horses.
A Sha-Dar (plural Sha-Darim) is a person with the rare ability to telepathically communicate with horses. They can sense what a horse is thinking as well as being able to calm them down and do many other things as well. A Sha-Dar is hailed as almost royalty in Algaria and the person gains instant nobility and riches when their gift is discovered. In Algaria celebrations go on for weeks at the discovery of a Sha-Dar.
The only Sha-Dar named in The Belgariad and The Malloreon is Hettar.
