Note: This article is about the uncorrupted region of Mirkwood, the Woodland Realm. You may be looking for Mirkwood Corrupted instead.
Mirkwood is a large forest in the north of Middle-earth that spans over much of Rhovanion.
It was once a vast and beautiful forest known as Greenwood the Great, or Eryn Galen, but was given its current name after nearly all of the region fell under Sauron's shadow over the course of the Third Age. Only a small portion in the north of the forest remained uncorrupted, which is known as the Woodland Realm.
This uncorrupted region is a sanctuary for the Wood-elves of Middle-earth, their ruler being King Thranduil, father of Legolas Greenleaf.
The area is heavily forested with Mirk-oaks (including the variation with red leaves) and various other trees from Vanilla and the mod, making it the ideal home for the nature-loving Wood-elves.
Upon entering this region of Mirkwood, you gain the achievement "Guest of the Elvenking".
Structures
Three structures spawn in Mirkwood.
Wood-elven Houses - Houses of the Wood-elves that spawn on the ground. A Mirk-oak grows through the center of the house. On the first floor is a chest plus bows and/or arrows that hang in item frames. On the basement floor, there are bookshelves and a Wood-elven bed.
Wood-elven Platforms - Small lookout platforms that spawn on the trunks of larger Mirk-oaks in Mirkwood. They are also called "Wood-elven Flets".
Wood-elven Towers - Towers of Wood-elven brick in the Mirkwood biome. A thin but tall Mirk-oak grows through the center of these towers. A staircase goes all the way up, and on each floor are four small balconies. On the top floor is a set of Wood-elven Scout Armor and a Wood-elf Captain. The staircase goes down to a basement floor, which has food, Wood-elven wine, tables, and a trapdoor to the dungeon, which contains three cells; occasionally, unarmed Gundabad Orcs or rarely some of Durin's Folk will spawn here.
Wood-elven Smithies - Circular structures that contain several Elven Forges, a crafting table, a Wood-elven Crafting Table, a chest full of loot, and two anvils. A Wood-elf Smith spawns inside.
Mobs
This biome is populated with Wood-elves, Wood-elf scouts, Wood-elf warriors, and Wood-elf captains (which spawn atop Wood-elven towers). Apart from NPCs, the black butterflies of Mirkwood spawn here, as well as cows, sheep, chickens, and pigs. No evil mobs spawn within the Woodland Realm, except for the Orcs in the cells in the dungeons of Wood-elven Towers..
Wood-elves - Male or Female, Wood-elves are Silvan Elves that spawn in Mirkwood and Wood-elf Houses.
Wood-elf Scouts - Wood-elf Warriors with bows and Wood-elven Scout Armor, which gives them a permanent Speed II effect.
Wood-elf Captain - Captains of the Wood-elves that reside in Wood-elven Towers. You can hire all of the above from them.
Mordor Orc - These Orcs spawn only in the dungeon cells of Wood-elven Towers in Mirkwood, and you do not have to worry about them here.
Dol Guldur Orc - Like the Mordor Orc, it too spawns only in the dungeon cells of the Wood-elven Towers.
Wood-elven Smiths - Smiths that spawn in Wood-elven Smithies, they sell weapons and armor and buy minerals.
Vegetation
Mirkwood is less densly forested than Mirkwood Corrupted. It contains Mirk-oaks, Red Mirk-oaks, Beeches, Vanilla oaks and Larches. Green Mirk-oaks can be of normal size or huge (these ones have Wood-elven platforms on them)..
