- For the primary universe counterpart, see Empok Nor.
In the mirror universe, Empok Nor was a Cardassian-built Nor-class space station, located in the Trivas system, that was stripped of technology and abandoned by its Klingon-Cardassian Alliance controllers. However, three Cardassian soldiers were left as sentries and would alert the Alliance should anyone illegally access the station. Others in the Alliance however referred it as "punishment detail" for unimportant or disgraced soldiers and ignored Empok Nor completely. (DS9 - Mirror Universe novel: Saturn's Children)
History
In 2375, soldiers of the Terran Rebellion boarded the station and, with no answer from their distress call to Terok Nor (which had been in rebel hands since 2372) the sentries were killed and the station captured. Rebellion Generals Zek and Julian Bashir, defying orders from their leader, General Miles "Smiley" O'Brien, to construct twelve individual ship-contruction facilities, instead turned Empok Nor's docking ring into a massive shipyard for the purpose of making Defiant-class warships for a future attack on the Alliance homeworlds' of Cardassia and Qo'noS. However, the Rebels drastically overestimated the station's structural integrity as it had neither weapon arrays or defensive screens to protect itself against an attack. Furthermore, the station's power core was taxed to the limit to power the industrial replicators being used to construct the warships, making it dangerously unstable. When the IKS Ya'Vang, under the command of Captain Kurn attacked the station, the fusion core exploded, destroying the station, the warships and many rebels.
