The Eastemnet was a part of Rohan, and an area of wide, grassy plains found east of the river Entwash, between it and the Great River Anduin.
The region was bordered by the lands of Anórien in the southeast, the Emyn Muil, marked by the East Wall of Rohan, in the east, the Wold of Rohan in the north, and Westemnet in the west. The land consisted of short and tall grasslands.
History
The region was the site of the death of Eorl the Young in a battle with the Easterlings in the Wold. In the past many herdsman and horse-lords wandered freely throughout the Downs of this land in temporary tent camps, but during the War of the Ring Éomer had the population take refuge in the Eastfold from increasing Orc raids.
There were few fixed settlements here, but many of the herdsmen of the Rohirrim lived a nomadic existence on the fields of the Eastemnet, living out of temporary camps and driving their herds across the grasslands.
Etymology
The name Eastemnet comes from the language of Rohan: the word Eastemnet in that tongue means 'east-plain'.
