Word of the Day: Palantir (pl. palantirí) are the ‘seven stars and seven stones’ , and its name meant, ‘which links far away.’
It came from Eldamar, beyond Westernessë, and was made by the Noldor. It is most commonly believed to have been made by Fëanor during his time in Aman. While Saruman could take anything to evil uses, it was his downfall.
Men used it to see and converse with one another, guarding the realm of Gondor. There are stones at Minas Anor, Minas Ithil, and at Orthanc (in the ring of Isengard).
Each stone replied to one another, and in Elrond’s house they were at Annúminas and Amon Sûl. Elendil’s stone was on the Tower Hills near Mothlonf in the Gulf of Lune with the grey ships. [Return of the King, ch. 11]
