Mithram

The Mithram (Sindarin for Grey Wall) is a mountain range in the southwestern Plateau of Gorgoroth, separating it from Nurn in the south. The Ennyn Ûr is set into this range, barring passage between the two regions. The dungeon of Nargroth was delved in this range, and it was here that Borangos the Horror awoke when Urudanî Stonemaiden delved too deeply.
