Horro was a khal who lived during the Century of Blood. He was the last great khal to command the allegiance of all Dothraki.
Horro slew Khal Moro and took control of his khalasar. He also took Moro's daughter, who had married the King of Gornath in an alliance between him and Moro, for himself. Three years later he was slain by a rival, and his great khalasar separated into a dozen lesser hordes.
