For many years, the Sirahna were in possession of the paghvaram, a fragment of one of the orbs of the Prophets. They used the artifact to create a creature called the Dal'Rok and make the Sidau's inhabitants join together in order to repel it. In 2369, the present Sirah made Miles O'Brien his successor when he realised his chosen successor Ke Hovath was not yet ready to assume the role. After O'Brien was unable to focus the inhabitants with his storytellng, Hovath stepped in and the Dal'Rok was driven away. (DS9 episode: "The Storyteller")
