In the mirror universe, Prynn Tenmei was a Terran female who lived during the 24th century. She was born in 2350 to the Terran slaves Elias Vaughn and Ruriko Tenmei. Her father had been an officer in the Imperial Starfleet prior to the conquest of the Terran Republic, the successor state of the Terran Empire, by the Klingon-Cardassian Alliance in 2295. Her father eventually ended up on Bajor as the property of Jaro Essa's family. As Jaro was a member of the Bajoran dissident movement which sought the withdrawal of Bajor from the Alliance, he was treated humanely and was eventually given his freedom. However, the pretense that he was Jaro's slave was maintained in order to prevent the Alliance growing suspicious.
