That's my take. Forested ranges like the Black Forest, Harz, or the Swabian Mountains are mostly connected to dwarf tales.Anyone ever think of maybe the old worn down ranges like the appalachians? Like the dwarves have been in the mountain so long it's worn down around them.
And Dwarves as Tibetan/Nepalese. Only because I haven't mined those cultures for role-playing purposes yet.
