In the mirror universe, Rom was a Ferengi mercenary-for-hire during the latter half of the 24th century. He was the son of Ishka, the younger brother of Quark and the father of Nog. He lived in the Klingon-Cardassian Alliance underworld while Quark owned and operated a bar on Terok Nor. He often assisted his brother any way he could to free the station's captive Terran population. After his death, Quark's was inherited by his son Nog, who was killed by the Intendant in 2372.
