According to the traditions of the Dwarves, Durin was set to sleep alone beneath Mount Gundabad in the northern Misty Mountains; Gundabad remained a sacred place to them ever after. He awakened some time after the creation of the Elves in Y.T. 1050, and according to an early version of the story[3] travelled great distances to other Dwarf kindreds, where other Dwarves joined him. He arrived at the Mirrormere, a marvellous lake in a great valley in the central Misty Mountains. In caves at the base of Celebdil, a massive peak that formed the western wall of the valley, Durin founded what became the greatest and richest of the Mansions of the Dwarves: Khazad-dûm (the Dwarrowdelf), afterward called Moria. Durin I was the first King of Khazad-dûm.
