What I find quite interesting is the Cardassian side of this equation. Why did they build two seemingly identical stations? Terok Nor was supposedly optimized for controlling and strip-mining Bajor. Was Empok Nor supposed to augment Terok Nor at Bajor, but was abandoned in mid-tow for some reason? Or was it destined for another conquered planet very similar to Bajor?
OTOH, if its location in the middle of nowhere was its intended assignment, why was it of the exact same shape and design as a station intended to operate on fairly low planetary orbit?
Maybe the Cardassians use a really flexible station design that can be used for ore processing or whatever when in orbit of a planet or as a dedicated military resupply and repair facility (if Empok Nor was intended to be out in the middle of nowhere). It would make building the things a lot easier, since you'd only need to pick different modules for each role while keeping the same design and structure for all the stations.
