Scrying
Scrying is an ancient art of divination by gazing into a crystal ball, a black mirror or even a still dark body of water any dark refelctive surface can be used. The word scrying means seeing. The "seer" is then supposed to see images that then must be interpreted by the scryer. In the 16th century most nobles had their own scryers. They were depended on to see the future.
