Rhovanion, or the Wilderland, was a large region of northeastern part of Middle-earth. The Great River Anduin flowed through it, and the immense forest of Greenwood the Great was a part of it. It was once known for being an organized realm of Northmen under name of the Kingdom of Rhovanion which fell in the wars with Easterling tribes, but the name was used for all of Wilderland by the late Third Age. Major features of this region were the forest of Mirkwood, the temporary desolation of Smaug, the rivers Anduin, River Running, and Redwater, and the Long Lake of Lake-town.
