Sirah was a Bajoran word for the leader and storyteller of Faren Kag's village. The first Sirah, seeing that the people of the village fought constantly, used a fragment of an Orb to channel the people's feelings into the Dal'Rok. Each year, the Dal'Rok would appear for five nights and threaten to destroy the village unless the people united. Whenever it appeared, the people believed the Sirah accomplished this by "telling the story" of how the village was stronger than the Dal'Rok, thus giving the impression that he controlled it when in fact the people themselves did so.
For a brief time in 2369, Miles O'Brien, a Starfleet officer stationed aboard Deep Space 9, was appointed Sirah. This angered Hovath, the previous Sirah's apprentice and hand-picked successor, as well as O'Brien, who did not want the job. However, O'Brien was not meant to be the Sirah; rather, Hovath had failed to unite the people and control the Dal'Rok previously, and by saving the village when O'Brien failed, he was able to prove himself capable in the eyes of the villagers. This was necessary, as they could not unite behind someone they did not trust. (DS9: "The Storyteller")
