In the mirror universe, Rigel V was under the control of the Terran Empire prior to its mass evacuation in the 2260s. Originally considered to be the jewel of the Rigel system, experiments with a variety of artificial bloods forced the evacuation of the planet when these bloods developed sentience, mobility and a predatory nature. Select evacuees only had a few hours notice before being beamed to Rigel III by a series of ships operating a transporter relay.
