Black Pit

One of several possible translations for the Elvish name Moria, given to the Dwarf-realm of Khazad-dûm after its people were driven out by the Balrog known as Durin's Bane. The name Moria comes from two Elvish words, mor meaning 'dark' or 'black', and iâ, which literally means 'gulf' or 'abyss'. The form 'Black Pit' was used by Gimli when he spied the Mountains of Moria as the Fellowship of the Ring journeyed southwards, but the alternative translation 'Black Chasm' is also sometimes used.

The Black Pit of darkened Khazad-dûm is not to be confused with the Black Pits, the dungeons that lay beneath Sauron's Dark Tower of Barad-dûr in Mordor.
