Númeriador

Númeriador or more properly Dúneriador is the region between the river Lune and the Blue Mountains. The largest settlement is the Dwarvish mines of the Nan-i-Naugrim, to which the refugees from the destruction of Belegost and Nogrod came early in the Second Age.

Númeriador is a corrupted form that appears on many maps, it is a mix of Sindarin and Quenya, Dúneriador is the actual correct sindarin form.
