Emyn Arnen was a cluster of hills located within South Ithilien across the Anduin from Minas Tirith.
Description
The hills, being an outlier of the Ephel Dúath, were situated south of Osgiliath, on the east bank of the Anduin, which made a loop around their feet.
The cartographic representation of Emyn Arnen has changed between the General Map of Middle-earth published in the The Lord of the Rings, where the hills are depicted in clear black lines, and the map of Unfinished Tales, where the hills are depicted as a dark silhouette with three peaks.
Old records preserved in Gondor indicate that Arnen was once used for the larger part of the region later known as Ithilien.
Emyn Arnen was home to a family of Númenórean nobles, and from them came Húrin of Emyn Arnen, who became steward to King Minardil of Gondor and later founded the line of the House of Húrin.
After the events of the War of the Ring, Faramir son of Steward Denethor II became the Prince of Ithilien and the Lord of Emyn Arnen, which became the dwelling-place of the White Company.
Many years into the Fourth Age, Pen-arduin, the home of Borlas, was located within Emyn Arnen.
