Wilderland is a massive biome that spawns between Mirkwood and Rhûn, south of the Iron Hills and North of the Brown Lands. It is the eastern part of the lands known as Rhovanion. The land is split in two parts by the area controlled by the Kingdom of Dale. Wilderland is vast and empty. Most of the lands are vast plains dotted with occasional trees. There are also small Wilderland Forest variants (which can also be Dense Wilderland Forests) and, bordering the Sea of Rhûn, the Wilderland Hills. Upon entering Wilderland, the player earns the achievement "Eastward Bound"
