Pact of the Ancients
Horn of Geryon
During the reign of the empire of Bael Turath this covert, tiefling, military order and dark cult worshiped the arch-devil Geryon, who had been previously and inexplicably exiled from hell by Asmodues. The horn were dedicated to working on the fringe of the empire as Geryon is forced to operate outside of the hierarchy of hell. They performed assassination and sabotage against their sworn enemies the dragonborn of Arkhosia.
