Tolkien Trewsday Week 162: Realms: Orcs
“Still far away, forty miles at least, they saw Mount Doom, its feet founded in ashen ruin, its huge cone rising to a great height, where its reeking head was swathed in cloud. Its fires were now dimmed, and it stood in smouldering slumber, as threatening and dangerous as a sleeping beast.”
“Behind it there hung a vast shadow, ominous as a thunder-cloud, the veils of Barad-dûr that was reared far away upon a long spur of the Ashen Mountains thrust down from the North. The Dark Power was deep in thought, and the Eye turned inward, pondering tidings of doubt and danger: a bright sword, and a stern and kingly face it saw, and for a while it gave little thought to other things; and all its great stronghold, gate on gate, and on tower on tower, was wrapped in brooding gloom.”
“Frodo and Sam gazed out in mingled loathing and wonder on this hateful land. Between them and the smoking mountain, and about it north and south, all seemed ruinous and dead, a desert burned and choked.”
“They wondered how the Lord of this realm maintained and fed his slaves and his armies. Yet armies he had. As far as their eyes could reach, along the skirts of the Morgai and away southward, there were camps, some of tents, some ordered like small town. One of the largest of these was right below them.”
Mordor, the Land of Shadow.
