|Region:||The Plateau of Gorgoroth|
Though only this part of the Ered Lithui is labelled as such, this mountain range actually forms the entire northern border of Mordor, and extends to Udûn and the Wastes to the west and Agarnaith and the Mokál Rukh to the east.
Two staircases provide access to the fortified lower slopes of the mountains. These slopes are haunted by many shadowy beings, and are watched over by three towers. Shadowed Pages for Lost Lore of Gorgoroth: Dor Amarth can be found at each of these towers.
