米那斯魔窟
The so-called Watchful Peace began in , when Gandalf went to Dol Guldur and the evil dwelling there (later known to be Sauron) fled to the far east. It lasted until 2460 T.A., when Sauron returned with new strength. During this period Gondor strengthened its borders, keeping a watchful eye on the east, as Minas Morgul was still a threat on their flank and Mordor was still occupied with Orcs. There were minor skirmishes with Umbar. In the north, Arnor was long gone, but the Hobbits of the Shire prospered, getting their first Took Thain, and colonizing Buckland. The Dwarves of Durin's folk under Thorin I abandoned Erebor, and left for the Grey Mountains, where most of their kin now gathered. Meanwhile, Sauron created a strong alliance between the tribes of Easterlings, so that when he returned he had many Men in his service.
