The Men-i-Mithrin bisected the
dangerous highway linking northern Rhûn to the Witch- realm of Angmar. Called the Men Rhúnen (S. "Eastern Way") or the "Rhúnnish Road," this fifth major north- ern route was used by the Witch-king's Men and Orcs to carry supplies and fresh troops westward from Rhûn. It ran north of the Iron Hills and along the southern edge of the Ered Mithrin before meeting the Grey Road in the gap north of Mirkwood. Further west, it passed above the great forest, across the river Mithlin (Greylin), up the Langwell Valley, and through the Misty Mountains at Gundalok, eventually reaching Carn Dûm.
