The Girl in Glass
The Gray Lord keeps a contingent of the hardiest Gray Knights at the fortress at all times and a powerfully armed dwarf battalion maintains a presence as well.
The fort is built atop a large mining operation that extends underground for miles and produces the finest iron ore in the region. Dwarf craftsmen forge weapons and armor from this iron and sell it at great profit to the outlying nations.
The city is largely off limits to travelers as the Dwarves are a secretive lot and fear for their monopoly of iron in the region. Their iron Caravans are heavily protected wagon trains commonly seen along the roads of Tanelorn.
