This was the northern wedge of Gorgoroth, which stretched from Udun to the foot of Orodruin, and from the Morgai in the west to the Gates of Barad-dûr in the east. It was a barren waste that consisted of broken rock and burnt stone, and the constant eruptions of Orodruin tended to go into this area, covering the plain in ash and dust, with many pits filled with foul fumes.
