During the days when Mirkwood was known as Greenwood the Great, the mountains were known as Emyn Duir or the Dark Mountains and were probably inhabited by Silvan Elves. The Giant Spiders of Mirkwood, and goblins have made their home here. The goblins were mainly newcomers to the mountains, fleeing into them after the Battle of Five Armies, where they built dwellings amongst the steep slopes.
