Orodruin, a volcano in Mordor, was the destination of the film series The Lord of the Rings in the quest to destroy the One Ring. Mordor, Shadow and flame, Sindarin Black Land and Quenya Land of Shadow was the region occupied and controlled by the Dark Lord Sauron. One does not simply walk into Mordor, its Black Gates are guarded by more than just Orcs, there is evil there that does not sleep, it is a barren wasteland, riddled with fire, ash and dust. the very air you breathe is a poisonous fume. Full of darkness and danger they were.
The Eye of Sauron, the Great Eye is ever-watchful, it is implied that Sauron has a physical body, a gigantic eyeball composed of energy.
But in the end, it’s only a passing thing, this shadow, even darkness must pass, a new day will come, and when the sun shines, it will shine out the clearer.
