The Imsogrek mountains are extensively honeycombed with mine shafts, tunnels, and cavern complexes. During the Horgon Era, the region was mined by Râpha-Sûn, then extensively exploited by the Tinnanguth Republic (340 - 817). They followed remarkably rich copper veins, with Imsogrek Copper found thousands of miles east in fledgling settlements like Ing-Serold. Before nationalist interests took hold, they stamped the copper with a mountain motif, coining the term Imsogreks for these prized copper coins.
Until the Year 400, Imsogrek mining was slow and often costly. The miners were primarily Sussgurd, now free people in Tinnanguth. Some were descendants of those who had toiled in the mines as slaves under Abâthigûr. In the fifth century, this dynamic began to shift with advancements in conjuration magic within Tinnanguth. Thereafter, the labor-intensive work became the domain of races adept at excavation, such as the Dao and earth elementals, who were brought in to perform the arduous tasks.
After the Dao Civil War, Tinnanguth's former slaves had become the new overlords of upper Karnegmoth. By that time, the mountains as far as Glascis had been thoroughly exhausted. This had left behind countless abandoned mines, tunnels, and former settlements. Currently, some of these regions serve as bases for Greenland guerrilla units.
