Norr-Dûm

While it was neither the oldest or the largest of the Grey Mountain colonies, Norr-dûm was the capital of Durin's folk.Chosen because of its central location in relation to the other Settlements, Norr-dum was the center of Dwarvish industry.The larger mining colonies, such as Thundercleft and Silver-pit, transported their ore overland to Norr-dum for smelting.Almost all of the forging of products was carried out here.Norr-dum sprawled over three levels,the lowest of which consisted almost entirely of mining tunnels.The second level was the main working area, although there were some Dwarf-lodgings, and the  Halls of Smithing were located here.The upper level consisted mostly of residential and administration areas.
