@epistomai @selzero The Palantíri are seeing stones that were originally a gift from the elves and installed all over the kingdoms of Gondor and Arnor as communication devices. Sauron got his hands on one of them after taking Minas Ithil/Minas Morgul. He then used it to spy on others, and drive Denethor insane. But the Palantír is not the Eye of Sauron.
