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.
In the Second Age, Noldorin Elves lived here due to the land and the West Gate of Moria. It was these Elves, led by Celebrimbor, son of Curufin (who was a son of Fëanor), 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. Now, it is an empty land.
Upon entering Eregion you gain the achievement "Faded Splendour".
Only two structures spawn here (not counting random, scattered blocks of Elven Brick).
Ruined Elven Turret- Ruined versions of the High Elven Turret. They can be pillars of Elven Brick or more like decayed versions of the High Elven Turrets. They are composed of Elven Brick. Note: The completed High Elven Turret does not generate here, or anywhere for that matter, but instead can only be generated by a structure spawner from creative mode.
Ruined Eregion Smithy - Ancient smithies of the elven-folk of Celebrimbor, all destroyed. But, in some, there still remains to be found forges and loot from the Second Age.
Eregion is in truth a fair land, despite the fact that only Orcs spawn here. It is mostly covered with trees, which are more concentrated in the forest. Eregion generally consists of oak and holly trees, although other trees grow as well. Larch is the only coniferous species here, albeit deciduous, and chestnut, birch, willow, apple, and pear are among the other broadleaf species. Holly trees can only be found in Eregion, and gave this land its nickname, Hollin, as well as the Elvish name, as ereg is the Sindarin term for holly. Apart from the trees, there are the average Minecraft flowers and grass growth, along with a few boulders of stone.
