In the year 2410, the Torhne led a squadron of Keldon- and other Hideki-class ships in defense of the interdimensional portal in the Badlands, leading to the mirror universe, against an Alpha Quadrant Alliance vessel and the USS Defiant. The AQA ships destroyed all True Way vessels, and the former AQA vessel journeyed to the mirror universe while the Defiant stayed behind. (STO - "Cardassian Struggle" mission: "Jabberwocky")
