Wrnach did little spying and rarely left Isengard, save under the most extreme of circumstances. Instead, he served as a clerk, coordinating Saruman’s reconnaissance activities. Working from a small chamber in the fifth portion of the ring-wall, Wrnach wrote reports that consolidated scraps of information from the spies, messengers, envoys, and message-birds from afar. Wrnach also listened carefully to the words of the informants who maintained discipline in Isengard, and used them to weed out any betrayal from within.
