Neither [Sam] nor Frodo knew anything of the great slave-worked fields away south in this wide realm, beyond the fumes of the Mountain by the dark sad waters of Lake Núrnen[.]

The Return of the King, The Land of Shadow

Núrn is a biome in the southern half of Sauron's realm Mordor, where his slaves grow crops. A large portion of Núrn is taken up by the Sea of Núrnen. There is grass here, and trees as well. This is the only place where Slaves of Núrn can be found, and they can be purchased here from Orc slavers.

The sky in Mordor is darkened by the ash and dust clouds coming from Mount Doom. This protects Orcs from debuffs during the day and trolls from turning into stone (though no normal trolls spawn here). In addition, evil mobs can spawn anytime, not only at night. Like the rest of Mordor, Núrn is not a good place for good-aligned players to be.

The roads in Núrn are made of Mordor Dirt, like the rest of Mordor.

Upon entering this region, the player earns the achievement "Slaves and Slavers".

Sub-biomes Edit

Sea of Núrnen Edit

The Sea of Núrnen, or Lake Núrnen, is a large sea located in the center of Núrn, in the south of Mordor. Its appearance is similar to the normal Ocean biome, but the water is brown like all water in Núrn. Four rivers (the Culduin, Sirlith, Caranduin, And Guthrant) flow down from the mountains into this sea. There can be small islands found in the sea as well.

Núrn Marshes Edit

The Núrn Marshes are a series of marshlands to the northeast of the Sea of Núrnen. There are two variants here: the uplands and the lowlands. The uplands are hillier and similar to a normal Minecraft swamp biome, albeit with less water. The lowlands are very flat, and made of many boggy pools.

Variants Edit

There are several biome variants of Núrn. They include:

  • Flowers - A version of Nurn with an abundance of flowers.
  • Forest - A more forested version of Nurn.
  • Steppe - A very flat version of Nurn.
  • Barren Steppe - A steppe, but with no trees. Structures generate here very commonly.
  • Hills - A hillier version of Nurn.
  • Mountain - A mountain that rises from the surrounding terrain.
  • Núrn swamp uplands (swamp only) - A forested and higher version of the marshes, with less water.
  • Núrn swamp lowlands (swamp only) - An almost flat portion of the marshes, full of quagmire and boggy pools.

Structures Edit

Mobs Edit

Note: Orcs and wargs do not spawn here as often as in Mordor itself, and there are no Olog-hai.

Mining Edit

Three ores are exclusive to Mordor, although no other ores spawn here as Mordor is made of Mordor StoneDurnaur ore spawns here, and is used for Orc torches among other uses. Morgul Iron is also exclusive to Mordor, and can be smelted into Orc SteelGulduril ore also spawns here, and is used (among other uses) for making Morgul portals back to the Overworld.

Vegetation Edit

Núrn is far more fertile than the rest of Mordor, due to ash blown over from Mount Doom. There is grass, sugar cane, stunted but living trees, and wheat in slave farms. It also contains the charred trees found in the rest of Mordor.

History Edit

When it was first added (in Public Beta 14), the Núrn biome had dark black-brown grass, very little vegetation, and stunted trees.

In Public Beta 23 it was redesigned to better fit the description of a fertile land. The water is still a dark, sad brown, but the grass now has a more healthy green colour. Stunted and charred trees still spawn in the biome, but now alongside more normal trees.
