About a century after the Elves awoke in Cuiviénen, the Seven Fathers of the Dwarves were roused. Of them, only the name of one is known, Durin I, who was called "the deathless". Each of Seven Fathers became a king of his own clan, and each built his own great hall. Three major holds are known to have been built in this period. Belegost and Nogrod were built in the Blue Mountains, and the Dwarves of these holds formed alliances with the Ñoldor and fought in their wars. Durin I, on the other hand, wandered into a vale in the Misty Mountains which he named Azanulbizar. In a still pool in that vale, he saw a reflection of himself with a crown of seven stars. Ever after, the constellation of stars that the Elves called Valacirca was called by the Dwarves Durin’s Crown, and it could be seen reflected in the water at any time of the day, though only Durin could see his own reflection. Durin I named the lake Kheled-zâram and proceeded to build his great halls of Khazad-dûm within the mountains above.
