Palantír
A palantír (pl. palantíri) is a fictional magical artefact from J. R. R. Tolkien's fantasy legendarium. A palantír (sometimes translated as "Seeing Stone" but literally meaning "Farsighted" or "One that Sees from Afar"; cf. English television) is a crystal ball, used for both communication and as a means of seeing events in other parts of the world.
