What is scrying?
Scrying (also called crystal gazing, crystal seeing, seeing, or peeping) is a magic practice that involves seeing things supernaturally in a medium, usually for purposes of divination or fortune-telling. The media used are most commonly reflective, translucent, or luminescent substances such as crystals, stones, glass, mirrors, water, fire, or smoke. Scrying has been used in many cultures as a means of divining the past, present, or future.
