The stone was aligned westwards towards the Master-stone in the Tower of Avallonë, along the length of the Straight Road; because of this, it could not communicate with the other six of Middle-earth. Only Elendil was able to use it to look west across the Sea and see the Undying Lands; but he could not see Númenor for it was covered by the bent seas for ever.
Even after the fall of Arnor, Wandering Companies of Elves made pilgrimages to visit the Towers and see the Stone, in order to catch a glimpse of Varda. One such company, led by Gildor Inglorion just returning from Elostirion, was encountered by Frodo, Sam and Pippin on September 24, T.A. 3018.
