Nargil Pass

Nargil Pass (or Cirith Núrn) (S. ’Fire Pass’). This pass was the origin of the Nargil river, and was one of the few ways that Southron troops could enter Mordor, and the main pass into Núrn. The other side of the pass was the headwaters of the Harnen River flowing south, the southern side was thus sometimes referred to as Cirith Núrn.
