Rhovanion, also known as the Woodland Realm, is a region in J.R.R. Tolkien's Middle-earth, primarily featured in The Lord of the Rings and The Hobbit. It is located east of the Anduin River and north of Mirkwood, characterized by vast forests and rolling hills. This area is home to various races, including Men, Elves, and Dwarves. The region plays a significant role in the history of Middle-earth, particularly during the events of the War of the Ring. Rhovanion includes important locations such as Lake-town and the Lonely Mountain, which are central to the quests of characters like Bilbo Baggins and Thorin Oakenshield.
