"Equal opposites"

The Phoenix encountered something that they would never thought they would see – an exact replica of their ship which had entered through a rift in front of them. The other vessel was the ISS Phoenix which had travelled through from the Mirror Universe in an attempt to capture the Prime Universe’s ship and take it back with them. The Mirror raiders boarded the Phoenix and attempted to take over, but were thwarted by officers O’Hannon and K’Lang once they made it to the bridge. The Mirror ship was handed over to the Galactic Commonwealth who came looking for them; a group of people dedicated to turning the Mirror Universe into a ‘safer’ place.
