The tunnels behind the iron mines above Rudbay on the East side of Faroth lead to a community of Forge Dwarves and Forge Gnomes. Their workshops produce meticulous magical works.
The Forge Domain of clerics (see Xanathar’s) is a good fit for the community of crafters below Faroth mountain. Their study of metallurgy is spiritual and highly disciplined.
