Mordor

Mordor is a dark land which Frodo and his friend Sam Gamgee travelled to. They had to pass the tower of Cirith Ungol in Mordor. Guarded by the black Watchers, Sam and Frodo were able to pass when Sam held up the elven-glass of Galadriel to them. the glass counteracted the deadly force of the glittering eyes, and the great gate, and the Watchers, were destroyed.
