During the War of the Ring, the watchtower of Cirith Ungol on the border of Mordor, is manned by a mixed trooper of Uruk-hai and small Orcs. Between the two kindred is bad blood and the tower is plagued with unrest. Gorbag is one of the Orcs patrolling the tower when Frodo and Sam attempt to pass that way. In the skirmish that follows Frodo's capture, Gorbag seeks to ensure that the Hobbit's confiscated possessions make their way safely to his Lord Sauron.
