Hollin

The barren, once-populous region west of the Misty Mountains formerly known as Eregion, featuring ruined walls, stoneworks, and the approach to the West-gate of Moria. It is overlooked by the peak of Caradhras.

Hollin, the ancient elven realm of Eregion west of the Misty Mountains, stands as a poignant reminder of faded glory in The Fellowship of the Ring, its ruined walls and stoneworks evoking the craftsmanship of Celebrimbor's people before Sauron's corruption. The Fellowship traverses this barren landscape, wary of its exposure, before pressing on to the perilous West-gate of Moria under the shadow of Caradhras. Though it appears only briefly in the series, Hollin symbolizes the enduring scars of elven history amid the quest to destroy the One Ring, with no further evolution or events in later books.
