Telepathic Communication in Middle-earth

[Ancalagon'sFire]

One must not forget the use of the Palantirs as a method of telepathic communication.

Quote: These stones were gifts of the Eldar to Amandil, father of Elendil, for the comfort of the Faithful of Númenor in their dark days, when the Elves might come no longer to that land under the shadow of Sauron. They were called the Palantíri, those that watch from afar; but all those that were brought to Middle-earth long ago were lost.

Remember that Sauron used this to communicate his commands with Saruman, and with Pippin and wrestled with Aragorn. Though they had been used in the past for exactly this purpose, not solely as a seeing-stone.
