He looked about, and then within the shadow of the gate he saw the Two Watchers.... They seemed to be carved out of huge blocks of stone, immovable, and yet they were aware: some dreadful spirit of evil vigilance abode in them. They knew an enemy. Visible or invisible none could pass unheeded. They would forbid his entry, or his escape. The Return of the King, Book VI, Ch. 1 The Tower of Cirith Ungol
Statues throughout Middle-earth are not always what they seem. The very stone of some statues hold the trapped spirit of malice within, crafted by the Dark Lord long ago with skilled workmanship and dark ritual. These ominous statues act as sentries and alarms within the realm of Angmar and throughout the lands corrupted by the shadow. Within many of the ruins throughout Eriador and Arnor, in lands once controlled by the darkness of Mordor's reach, these watchers remain, ever-vigilant even after centuries of abandonment.
Inspired by the Two Watchers at Cirith Ungol in
The Return of the King, watcher statues can be found throughout LOTRO. Cautious adventurers will be wary of any statue, for there is little outward difference between a Watching Stone and common statues found throughout the ruins of Angmar.
