Nazgûl arrive in Isengard to confront Saruman
Event Type: General
Age: 3rd Age - Ring War
Date: September 18, 3018
[The] Lord of Morgul halted before the Gate of Isengard.... But [Saruman] was wary and cunning still, and he had ordered Isengard against just such an evil chance. The Circle of Isengard was too strong for even the Lord of Morgul and his company to assail without great force of war. Therefore to his challenge and demands he received only the answer of the voice of Saruman, that spoke by some art as though it came from the Gate itself.
