Empok Nor (mirror)

In the mirror universe, Empok Nor was a $𝜇$-built 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 referred it as "punishment detail" for unimportant or disgraced soldiers and ignored Empok Nor completely. (DS9 - Mirror Universe novel: Saturn's Children)

History
In the year 2375, soldiers of the Terran Rebellion boarded the station and, with no answer from their distress call to $𝜇$ (which had been in rebel hands since 2372, the sentries were killed and the station captured. Rebellion Generals $𝜇$ and $𝜇$, 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 warships for a future attack on the Alliance homeworlds of $𝜇$ and $𝜇$. 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, under the command of Captain $𝜇$ attacked the station, the fusion core exploded, destroying the station, the warships and many rebels. (DS9 - Mirror Universe novel: Saturn's Children)

In a permutation of the mirror universe where the rebels' plan succeeded, Empok Nor was controlled by the resurgent Terran Empire in the early 25th century. From 2410 onwards, Empok Nor was one of the Terran starbases transported to the Badlands of the primary universe to build a staging point. The attacks were led by Admiral $𝜇$ from the. The Alpha Quadrant Alliance succeeded in pushing the Terrans back into their own realm. (STO mission: "Badlands Battlezone")
