For the regular universe counterpart, see Mogh.

In the mirror universe, Mogh was the Klingon father of Worf and Kurn. Although his family had many influential allies, Duras was an enemy of the House of Mogh.

After Worf's capture by the Terran Rebellion in 2375, the House of Mogh was disgraced, although it was allowed to keep its lands and titles thanks to its allies' influence. The house's honor may have been restored after Kurn scored a massive victory by destroying eleven Defiant-class starships at the Rebel shipyard Empok Nor. (DS9 novel: Saturn's Children)
