(coexisting on another dimensional plane)
Bareil Antos was a thief from the mirror universe who was sent by Intendant Kira to steal the Orb of Prophecy and Change and return to the mirror universe to start a new religion to unite Bajor against the Klingon-Cardassian Alliance.
Bareil came to Deep Space 9 using a multidimensional transporter device, and promptly took Major Kira Nerys hostage, but released her shortly thereafter, beginning a brief romance. Kira introduced him to the many differences between the parallel Bajors, including different foods and the Bajoran religion. Kira arranged for Bareil to have an Orb experience, which appeared to deeply affect him.
Many Bajorans stared at Bareil because of his identical resemblance to his counterpart, the late vedek, which puzzled Antos before his orb experience and caused deep consternation within him thereafter, as he wondered if he really could take the role of a spiritual leader.
He began to bristle against the Intendant, though he continued with the plot to steal the Orb, believing himself to be truly irredeemable. However, while confronting both Kiras at the last minute, Bareil chose to stun the Intendant and return both her and himself to the mirror universe, without the Orb, forfeiting the prophecy of his Orb vision - a happy life with Major Kira.
