The Master Stone; The great Seeing Stone that stood beneath the Dome of Stars in Osgiliath. It was the chief of the palantíri of Middle-earth, and had power over the other Stones (it is known, for example, that it had the unique ability to observe conversations between the users of other palantíri). When Osgiliath was besieged by Castamir in III 1437, the Tower that held the Stone of Osgiliath was broken, and the Master Stone was lost in the Anduin. #palantíri # Osgiliath #lotr #tolkien#letstalkarda
