For questions about magical seeing stones called "palantíri" from JRR Tolkien's Lord of the Rings books. The palantíri, also known as the Seeing Stones, are objects used for both communication and as a means of seeing events in other parts of the world. Always use in conjunction with the [tolkiens-legendarium] tag.
The palantíri (sometimes translated as "Seeing Stones") were stones that could be used in communication with one another, and also to see many things across the face of the world. When its master looked in it, he could communicate with other Stones and anyone who might be looking into them; people of great power can manipulate the Stones to see virtually any part of the world.
