Origin: Bajoran wormhole
According to Bajoran religious doctrines, the prophets are the spiritual protectors and guides to the Bajoran peoples.
Throughout Bajoran history, several unusual objects referred to as "Orbs" have found their way to Bajor, where they are traditionally considered to be messages of wisdom from the prophets to the Bajoran people. There have been nine orbs total, each associated with a unique and important aspect of the Bajoran belief-system.
