Orb of Prophecy and Change
The Orb of Prophecy and Change was an Orb of the Prophets, also occasionally referred to as the Orb of Change or the Orb of Prophecy. It is considered to be very powerful, causing intense encounters that prove draining even for healthy people. Bajoran Religion holds that the orbs were sent by the Prophets of the Celestial Temple to guide the people of Bajor.
The orb was the third of nine orbs that appeared on or near Bajor, approximately 10,000 years ago. It has influenced many religious figures including the spiritual writer Trakor, who encountered the orb some 3,000 years ago, and later wrote a series of prophecies concerning the Emissary of the Prophets.
