In the mirror universe, Kestra Troi (2329-2371) was a Betazoid / Terran hybrid who lived during the 24th century. She was the daughter of Lwaxana and Ian Troi and the elder sister of Deanna Troi. As a child, Kestra tried to teach Deanna methods of creating mental shields that would keep their mother out of her mind. Once she was older, she ran away from Betazed to find her father, but by the year 2371, she had not been able to do so.
