Thanks to the absurdly rich resources of various metal ores from the surrounding mountains, this city boasted a highly developed mining and metallurgy industry.
Moreover, due to its ruler, the Great Duke "Dispater's" fervent pursuit of high-end technology and military might, the myriad manufacturing workshops and armories made Steel City the most renowned production hub of munitions in the Multiverse, supplying military weapons ceaselessly to war enthusiasts of all kinds.
