The Ered Lómin was the grey mountain range that marched north to south between the land of Hithlum to the east and the lands of Lammoth and Nevrast to the west. At its southern end the Ered Lómin met the range of the Ered Wethrin and so walled off Hithlum and its lesser lands from Beleriand to the south. The Ered Lómin was broken by the inlet of the Firth of Drengist.
It was through the Firth of Drengist in these mountains that Fëanor led his followers among the Noldor back into Middle-earth.
