We have now come to the River Hoarwell, that the Elves call Mitheithel. It flows down out of the Ettenmoors, the troll-fells north of Rivendell, and joins the Loudwater in the South.

–Aragorn in The Fellowship of the Ring, Flight to the Ford

The Ettenmoors is a biome in Middle-earth far to the north. It is bordered to the north by a stretch of the Misty Mountains as well as Angmar, to the west by the Lone-lands, to the east by the Misty Mountains, and to the south by the Coldfells. It has a climate and flora much like that of the Northern Forests. The landscape is dominated by rolling hills, scattered boulders and evergreen trees.

This rugged area has two faces, both saddening to any adventurous Hobbit or Elf. The day is ruled by the savage hillmen of the Rhudaur, who seem to be capable of not only surviving in this harsh realm, but also to coexist with the rulers of the night. Animals are less abundant and anything fluffy or cuddly seems to have left the area. The remaining elk and wolves benefit from lack of competition. At night, more sinister creatures rule. As soon as the thin sun sets, orcs, wargs, trolls, and hill-trolls take over.

Troll hoards and ruined towers hold treasure for the adventurous. But beware, as the Ettenmoors is frequently invaded by forces of Angmar, Gundabad and the Dúnedain of the North.

Upon entering this biome, the player earns the achievement "The Troll-fells".


The Ettenmoors is defined as a 'mountains' biome variant which includes the following biome variants:

  • Standard - Normal mountaineous Ettenmoors biome. This has high elevation differences and results in a 'rolling hill' landsscape. As the climate is cold, snow can be found covering hills and treetops at relatively low altitude.
  • Forested mountains - Forest covered mountaneous rolling hills.
  • Lightly forested mountains - Lightly forested mountaneous rolling hills.

Structures Edit

The Ettenmoors are a barren land, yet the occurence of non-natural structures is striking. Among many towering remnants of old ruined structures of Arnorian, Angmarian and undefined origin, the following structures can be found:

Mobs Edit

Not very many mobs spawn during the day, but the following spawn during the night:

Conquest Edit

Ettenmoors can be conquered by Dúnedain of the North, High Elves, Gundabad and Angmar. The conquest rate is 0.75.

Vegetation Edit

Wolf Trio

A lone trio of Wolves wanders among a field of boulders.

The Ettenmoors have a taiga-like, boreal, coniferous vegetation, which is covered with snow at higher altitudes. Because of the cold climate, vegetation, like in most frigid areas, is fairly limited to a select few, hardy species, including spruce, fir and pine trees dominate the landscape, regardless of elevation. Very rarely, the player may be able to find athelas, a hint at the occupation of Rhudaur. Flowers are more rare in this harsh climate than in most, but grass growth is generally average.

Trivia Edit

As of Public Beta 28 the terrain generation of this biome creates a more rugged terrain. This biome is generated using the same routine as the Emyn Winion, but in a little less extreme manner.
