In the mirror universe Deanna Troi was security chief on the ISS Enterprise-D during the Terran Empire's final days of its war with the Klingon-Cardassian Alliance. She and Jean-Luc Picard murdered Beverly Crusher. They wanted to dispose of Wesley as well, but the war left a shortage of all officers, and someone with Wesley's talents was considered indispensable (The Final Days).
