This article is about the biome. For the faction, see here.

It is clad in a forest of dark fir, where the trees strive one against another and their branches rot and wither. In the midst upon a stony height stands Dol Guldur, where long the hidden Enemy had his dwelling. We fear that now it is inhabited again, and with power sevenfold. A black cloud lies often over it of late.

–Haldir, The Fellowship of the Ring

Dol Guldur (Sindarin for Hill of Dark Magic/Sorcery) is the realm in Mirkwood from which the evil festers. Sauron himself resided here (then under the alias of The Necromancer) before moving his stronghold to Barad-dûr in Mordor. It was afterward ruled by Khamul, one of the Nazgûl.

It would be unwise for players with a negative Dol Guldur alignment to set foot unprepared (and if you think you are prepared, you likely are not) in this biome. A murky fog covers the land, making it possible for all manner of evil creatures to spawn both day and night. Mirkwood spiders are not the only mobs that dwell here; there are also Orcs and trolls as well (see below), making this place even more inhospitable than Mirkwood

Webs of Ungoliant can be seen everywhere, and stepping into the poisoned water will give the player Slowness II, Weakness, Mining Fatigue II, and Blindness for 30 seconds. 

Entering this region will earn the player the achievement "Hill of Sorcery".

Structures Edit

The following structures spawn in Dol Guldur among the piles of Dol Guldur bricks:

Hill of Dol Guldur.

Hill of Dol Guldur.

The hill of Dol Guldur can be found at the Dol Guldur waypoint. It peaks at about y:120 and structures can spawn here, as well as a road that ends at the top. This is an excellent place to build the fortress of Dol Guldur.

Mining Edit

Dol Guldur has the same ores as the rest of Middle-Earth, and underground there also generates Morgul Iron and Gulduril ore. This ore is in stone, like in Angmar, not in Mordor Rock, like in Mordor. Morgul Iron is smelted into Orc Steel, which is used in Dol Guldur equipment, and Gulduril can be alloyed with it to make Morgul Steel.


Apart from the grass and occasional fallen leaves, only dark green Mirk-oak trees thrive here. Many are dead, however, and grow no leaves. The corruption caused by the Necromancer in Mirkwood is strongest here, and the dark forest cedes from the hill of Amon Lanc. Along rivers, however, pines find a way to grow in the blight of Dol Guldur. The grass is scrubby and a murky green-grey. Flowers refuse to grow.

Lore Edit

Dol Guldur was Sauron's fastness after returning to Middle Earth after War of the Last Alliance. At this time, (TA 1000) Sauron's identity was hidden, and was known as the Necromancer. The original name of the Hill upon which it was built was Amon Lanc, the ancient dwelling of the Mirkwood. After Sauron captured the Fortress, the Elves fled over the river, where they remained. Even after Gandalf told the White Council about his suspicions, Saruman continued not to approve an assault. Gandalf later went to Dol Guldur himself, where he discovered that the Necromancer was indeed Sauron. The White Council then banished Sauron from Mirkwood, after which he fled to Mordor, where he remained until the War of the Ring.

In 2951 Dol Guldur was reoccupied by Khamûl, the second chief, and two other Nazgûl. In the following decades Dol Guldur must have rebuilt some of its power until the War of the Ring, during which its forces made assaults upon the Woodland Realm and Lórien, causing grievous damage to the outlying woodlands. Dol Guldur was finally destroyed and cleansed by the Elves of Lórien, led by Galadriel, after Sauron's fall.
