The oldest folk of the Dwarves. Durin's Folk were never as greedy as other clans became. They originally inhabited Khazad-Dum in Moria, for that was where Durin I awoke. They were forced out by an angry Balrog and orcs. They moved to the Lonely Mountain, where they were again removed. They then retreated to the Blue Mountains until they reclaimed the Lonely Mountain.
