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

One does not simply walk into Mordor. Its black gates are guarded by more than just Orcs. There is evil there that does not sleep. The great Eye is ever watchful. It is a barren wasteland, riddled with fire, ash, and dust. The very air you breathe is a poisonous fume.

The Fellowship of the Ring (film)

Mordor (Sindarin for Black/Dark Land) is a biome that spawns to the east of Gondor, to the west of Rhûn, north of Harad, and south of Wilderland. The biome is dark and evil and the homeland of the Mordor Orcs, Black Uruks and Olog-hai. There are lava lakes, ravines, and rivers, making these lands dangerous for both good and evil. The ground is made completely out of black Mordor Rock, with patches of Mordor Dirt and Mordor Gravel, which adds to the dark atmosphere of Mordor. Scattered across the landscape, large dark boulders and large amounts of lava bear witness of frequent volcanic eruptions. Only "evil" plants grow here: thorns, Morgul-shrooms and Withered Moss. As reminders of a long-forgotten past, charred trees can be found throughout these lands.

The sky in Mordor is darkened by the ash and dust clouds coming from Mount Doom, and blots out both the Sun and Moon. This protects Orcs from debuffs during the day. In addition, these mobs can spawn at any time, not only in the night. Because of this, Mordor is not a good place for good players to be unless you are very well prepared and want to get some alignment.

The roads in the Black Land are made of Mordor Dirt.

Upon walking into Mordor, the player earns the achievement "One Does Not Simply..."


Mordor MountainsEdit


The towering mountain-borders of Mordor.

These Mountains exist all around Mordor except at the east border. They are actually three mountain ranges: the Ered Lithui (Ash Mountains) to the north, the Ephel Duath (Mountains of Shadow) to the west and southwest, and the unnamed extension of the Ephel Duath to the southeast, but are the same sub-biome in the mod. They consist of Mordor Stone and form an nearly impassable wall that protects the heartland of Mordor. Mordor Towers are the only structures that generate here. 



The Udûn Road runs through a knot of camps.

Udûn is a valley in the northwest of Mordor. The ground there is rough and jagged, and there are more structures than the normal Mordor biome - especially camps. If the countless Orcs were not dangerous enough, there are many lava-filled ravines in Udûn, which lead many to their deaths.


Gorgoroth (Sindarin for Deadly Fear) is a plateau that makes up most of the northwestern region of the Black Land. The ground here is higher and is significantly flatter than the rest of Mordor, and as with Udûn all Mordor mobs and structures are more common than normal. However, the flatness of the ground means that there is no cover for good players - making it all the more deadly. In the very center of this dreadful place is Mount Doom, a fearsome volcano that is the center of Sauron's power, the forging place of the One Ring, and the only place where that Ring can be unmade.

Morgul ValeEdit

PB29 preview - new flowers in Morgul Vale

The 'fertile' Morgul Vale.

The Morgul Vale is the accursed vale where the Nazgûl make their home. The sky in the Vale is a greenish hue. The soil is moderately fertile and supports green grasses and trees. Normal, desert and dead oak trees grown here on the sickly green grass. In addition, Morgul-flowers grow abundantly here; these are no ordinary flowers indeed, for they give nausea, slowness, weakness, and blindness to anyone with under +250 Mordor alignment simply by being near them them. Stepping on them gives those and poison.

Gulduril Ore is more common here, and generates starting at Y = 60 as opposed to Y = 32.


The Morgulduin is a cursed river that flows through the Morgul Vale. Although Morgulduin is the name of a major river in Mordor, the sub-biome also randomly generates throughout the Morgul Vale in place of the Mordor River variant. Entering the waters give you the status effects Slowness II, Mining Fatigue II, Poison, and Weakness, unless you have 100 Mordor alignment, in which case you are immune.

Nan UngolEdit

Also called the "Valley of Spiders," Nan Ungol is located in the south-west corner of Mordor. Exclusive to this region are the Mordor Spiders, that can be ridden by Orcs. Mordor Spiders can be bought from Mordor Spider Keepers in Spider Pits. Webs of Ungoliant are scattered all over, and there are more trees here than normal - though all are charred and dead.

Mordor RiverEdit

Mordor once had a different river biome which had black water, though now the normal river biome generates here in the same manner. Four rivers are automatically generated by the map to flow down into the Sea of Núrnen; two from the Ash Mountains, one from the western Mountains of Shadow, and one from the southern mountains. Apart from reed and cane, there are no larger plant species present to suggest that the river waters are feeding any life significant life forms ... until they reach Núrn.


Núrn (Sindarin for Sad) is the only fertile region of Mordor and is located around the Sea of Núrnen in the south of Mordor. There grows grass and other plants. The land is fertile because of the rich ash that is blown by wind from Mount Doom. In Núrn live thousands of human slaves, working on farms to produce food for the thousands of Orcs in Mordor. You can purchase Slaves of Núrn from Orc Slavers found in Orc Slaver Towers. Small forests and swamps can occasionally generate here as well. Occasionally patches of Núrn Forest will generate, and Núrn Swampland generates around the points where the various rivers in Núrn empties into the Sea of Núrnen. The fertility of Núrn is only skin-deep, as directly under the topsoil layer is yet more Mordor Rock.

Sea of NúrnenEdit

This sea is located in the center of Núrn, in the south of Mordor. Its appearance is similar to the normal Ocean biome, but the water is a dead brown like all water in Núrn. Four rivers flow down from the mountains into this sea. There can be small islands in the sea.

Eastern DesolationEdit

The Eastern Desolation is a strip of land that makes up the eastern border of Mordor. The Eastern Desolation is a flat plain of Mordor dirt and gravel. Dry grass is more abundant here than elsewhere in Mordor, and there are more charred trees signaling this was once a different place, before some calamity destroyed it in ages past.


Mordor itself is unique in that it has no biome variants. The sub-biome of Núrn does, but those are listed on that respective page.


Several structures spawn in Mordor. They are listed below.


Sauron has many evil servants living in his realm of Mordor.

Mobs spawning throughout all of Mordor Edit

Mobs spawning only in Nan Ungol Edit

  • Mordor Spider - Large spiders that spawn in Nan Ungol. They come in different sizes and inflict poison on enemies. They can be ridden by Mordor Orcs and archers. They can be bought from Mordor Orc Spider Keepers. These spiders can be tamed and ridden by evil players only.
  • Mordor Orc Spider Keeper - Mordor traders that spawn in Mordor Spider Pits from whom you can hire Mordor Spiders. They hold a silver coin in their hand to show that they are traders.

Mobs spawning only in Núrn Edit

Fixed StructuresEdit

Mount Doom Edit

Mount Doom, otherwise known as Orodruin, the great Mountain of Fire, is the one place in Middle-Earth where the One Ring can be destroyed and Sauron ended forever. However, its location in the middle of Gorgoroth makes this hard to achieve.

In the mod, Mount Doom generates just south of the waypoint of the same name. It is a great mountain of Mordor Rock, with a volcanic crater at the top.


Three ores are exclusive to Mordor, although no other ores spawn here as Mordor is made of Mordor Rock. Durnaur Ore spawns here, and is used for Orc Torches among other uses. Morgul Iron is exclusive to Mordor, Angmar, and Dol Guldur, and can be smelted into Orc Steel. Gulduril ore also spawns here, and is used (among other uses) for making Morgul portals back to the Overworld.


Only a few plants grow in Mordor. Trees are usually dead and the vegetation forms a very hostile environment as some plants will try to harm you. There are, however, mysterious reports of a giant cherry-like tree in the biome.

Plants found in the main biome are:

  • Burnt trees (trees without leaves, so you can't get saplings from them).
  • Stabbing Thorns, which deal damage to players who walk through them.
  • Withered Moss, brownish and dead vegetation.
  • Morgul-shrooms (at orc camps) which can be used as a food source by evil players and are required for brewing orc draught.

The land of Núrn is more fertile, so it has dry grass, trees, sugar cane and even wheat at the slave farms.
