In the mirror universe, Tekeny Ghemor was the director of the Obsidian Order for the Klingon-Cardassian Alliance for almost 25 years during the 24th century. He was married to Kaleen Ghemor, with whom he had a daughter named Iliana Ghemor.
His daughter would herself join the organization, but subsequently defected to the Terran Rebellion under Miles "Smiley" O'Brien. She would later describe him as a cold, heartless man. (DS9 novel: Fearful Symmetry)
