In the mirror universe, General Kor was a Klingon male who lived during the 23rd century. In 2282, Kor met with a Ferengi black marketeer named Lorp on Cestus III to order to obtain information regarding a top secret project being run by the Imperial Starfleet aboard the supposedly abandoned Regula I Space Laboratory at the edge of the Mutara Nebula. Lorp's payment was a complete set of holographic schematics for a cloaking device. However, after reviewing the data, Kor's guards Gejh and K'mdek killed Lorp and his two henchmen using their disruptors. (TOS - Mirror Universe novel: The Sorrows of Empire)
