On the eastern slopes of
Lornar's Pass, north of
Camp Rankor rests the deep, slag-strewn expanse of
Grenth's Footprint. Once a sacred place for the
dwarves of Deldrimor, the peak itself has been completely dismantled, and the land torn open to get at the precious metals beneath the soil. The
Stone Summit have dug deep into the
Shiverpeak Mountains. Underneath the stripped, barren land, are the all-but-depleted mining shafts of
Sorrow's Furnace.
