In the mirror universe, T'Lara was an elderly Vulcan woman in the late 24th century. She was a member of Memory Omega and trained the Terran operatives Keiko Ishikawa and Tasha Yar. Prior to 2375, T'Lara had shown Keiko holovid footage of Grand Admiral Spock's usurpation of the throne of the Terran Empire in 2277, which he accomplished by making his predecessor Hoshi Sato III vanish into thin air.
