Middle-earth locations
In the Third Age, the dwarves woke a Balrog deep in the mines of Khazad-dûm. The Balrog killed King Durin VI and many Dwarves. The dwarves that were not killed were forced to leave Khazad-dûm and find other places to life. Khazad-dûm got a new name, Moria. In Sindarin. Moria means "dark pit".
