Dol Guldur, the infamous Hill of Dark Sorcery, was the hidden stronghold of Sauron as he secretly rebuilt his strength under the guise of The Necromancer. Located deep in the southern reaches of Mirkwood, this dark fortress stood as a bastion of evil for nearly two thousand years of the Third Age. It not only served as Sauron’s base of operations but also as a stronghold for countless Orcs, looming over the forest as a symbol of fear and shadow.
