It was thought to be a Bajoran legend that told of false Prophets who were cast out of the Bajoran Celestial Temple. The Bajoran word Koss'moran came from the verb kosst that meant "to be," and amoran, which meant "banished." (DS9: "The Assignment") In 2374, the Kosst Amojan inhabited the body of Jake Sisko in order to bring forth the Reckoning. The possession was ended after Kai Winn Adami flooded the station with chroniton radiation. (DS9: "The Reckoning")
