Eregion

"Gandalf stood at Frodo's side and looked out under his hand. 'We have done well,' he said. 'We have reached the borders of the country that Men call Hollin; many Elves lived here in happier days, when Eregion was its name."

- The Fellowship of The Ring, The Ring Goes South

Eregion (also known as Hollin) was a great kingdom of the Noldorin Elves in Eriador during the Second Age. Orcs spawn here at night. Eregion is full of ancient structures such as Elven ruins and Ruined Elven Turrets. Holly trees are exclusive to this biome.

In the Second Age, Noldorin Elves lived here due to the land and the West Gate of Moria. It was these Elves, l ed by Celebrimbor, son of Curufin (who was a son of F ë anor), who made the Rings of Power. The survivors were led out of Eregion by Elrond when Sauron invaded the land, and from then onward lived in Rivendell.

Upon entering Eregion you gain the achievement "Faded Splendour."

Sub-biomes
There are two sub-biomes in Eregion.

Eregion Forest
The Eregion Forest sub-biome is similar to normal the Eregion biome, but it has a denser concentration of holly and oak trees.

Eregion Hills
The Eregion Hills is a more mountainous sub-biome of Eregion. It is like Eregion, but is more mountainous.

Structures
Only one structure spawns here (not counting random, scattered blocks of Elven Brick).
 * Ruined Elven Turret- Ruined versions of the Elven Turret. They can be pillars of Elven Brick or more like decayed versions of the Elven Turrets. They are composed of Elven Brick. Note: The completed Elven Turret does not generate here, or anywhere for that matter, but instead can only be generated by a structure spawner from Creative Mode.

Mobs
The only NPC mobs here are the foul creatures of Gundabad, which spawn at night or underground. Otherwise, the land is populated with passive animals such as cows, rabbits, and sheep.
 * Gundabad Orc- Orcs from Mount Gundabad in the Misty Mountains allied only to themselves.
 * Gundabad Orc Archer- Gundabad Orcs with bows and arrows.
 * Gundabad Wargs- Wargs allied with Gundabad (can spawn with a Gundabad Orc or Orc Archer mounted on them)

Vegetation
Eregion is in truth a fair land, despite the fact that only Orcs spawn here. It is covered with trees (more concentrated in the Eregion forest) of two types: chesnut trees and holly trees. Holly trees can only be found in Eregion, and gave this land its nickname, Hollin. Apart from the trees are the normal Minecraft flowers and grass, along with a few boulders of stone.
