Scrying, also known by various names such as "seeing" or "peeping", is the practice of looking into a suitable medium in the hope of detecting significant messages or visions. The objective might be personal guidance, prophecy, revelation, or inspiration, but down the ages, scrying in various forms also has been a prominent means of divination or fortune-telling.
Scrying mirrors are a divination tool for looking into past lives, and past, present, and future events.
The black scrying mirror, also known as the "magic mirror" is a powerful metaphysical tool. It can reveal to the user secret hidden knowledge and clairvoyant ability and can act as a portal to other planes of existence in our universe.
One of its most famous known users was Nostradamus, who could tell by staring into the mirror events far into the future.
