Apr 6, 2018 - Moria, or Khazad-dûm, was founded by Durin the Deathless. Durin awoke at Mount Gundabad, in the Misty Mountains, in the period of time known as the Years of the Trees, and came upon a shimmering lake beneath the mountain Celebdil with a crown of stars reflected in its waters. He named it Kheled-zaram as it was known in Dwarvish tongue, the Mirrormere. Thereafter it remained a revered place amongst the Dwarves. In the caves above the lake, Durin's folk built Moria.
