Gandalf learns Saruman is in control of a mysterious black orb referred to as a palantíri in The Lord of the Rings. These stones were utilized for connection among all those who had one, with Sauron utilizing his to secretly communicate with Sauron. However, based on how they impacted Pippin when he grabbed one, it’s clear that the palantíri are up to something far more terrible.
The palantíri (also called Seeing Stones) permitted their bearer to see a glimpse of people who held the other and converse with them across enormous distances, as depicted in The Lord of the Rings films. These stones were especially powerful in a world without electronics, but Gandalf disapproved of them since some palantíri were unaccounted for, implying that anybody in Middle-earth may be spying on them.
J. R. R. Tolkien elaborated on them through various notes and supplements, as he did with many other items in the realm of Middle-earth. The palantíri are claimed to have been fashioned by Elves in the early eras of Middle-earth and subsequently given to the race of Men. To make the most of their communication abilities, the Seven Stones were housed far apart across the land from one another. Many of the stones were lost or destroyed throughout time as a result of battles and natural disasters until just two existed in Middle-earth.
In terms of palantíri characteristics, the stones were unable to send an exact image to the others. Instead of having audible discussions, they would exhibit visuals in the users’ heads and transmit thoughts. And only two users may communicate with each other at the same time. Much larger Master Stones, on the other hand, might listen in on other people’s talks, however, nothing is recorded about their whereabouts. This is why, in The Lord of the Rings, Pippin saw a sight of Minas Tirith while holding one, as Sauron was fixated on planning the attack on the city. Fortunately, the palantíri and their users were unable to force their way into the brains of others. However, it was also hard for users to create fictitious sights, which was why Gandalf was concerned about what Pippin said to Sauron. Pippin may have unintentionally thought of Frodo and their intentions, which Sauron may have seen and used against them.
While some artifacts in Middle-earth could be either good or evil by nature, the palantíri took no sides. For a while, they were utilized for good, as a means of communication between Men’s rulers. They were, however, just as potent in the hands of an evil force like Sauron. The palantíri suffering was caused by seeing into Sauron’s thoughts, but it turned out to be a major benefit for the Fellowship because they knew Sauron’s next battle plan.
