Now the Eldar were beyond all other peoples skilled in tongues; and Felagund discovered also that he could read in the minds of Men such thoughts as they wished to reveal in speech, so that their words were easily interpreted.- Silmarillion; Of the Coming of Men into the West
Soon Celeborn and Galadriel and their folk would turn eastward, and so pass by the Redhorn Gate and down the Dimrill Stair to the Silverlode and to their own country. They had journeyed thus far by the west-ways, for they had much to speak of with Elrond and with Gandalf, and here they lingered still in converse with their friends. Often long after the hobbits were wrapped in sleep they would sit together under the stars, recalling the ages that were gone and all their joys and labours in the world, or holding council, concerning the days to come. If any wanderer had chanced to pass, little would he have seen or heard, and it would have seemed to him only that he saw grey figures, carved in stone, memorials of forgotten things now lost in unpeopled lands. For they did not move or speak with mouth, looking from mind to mind; and only their shining eyes stirred and kindled as their thoughts went to and fro.
