N ecromancy is the act of conjuring the dead for divination. It dates back to Persia, Greece and Rome, and in the Middle Ages was widely practiced by magicians, sorcerers, and witches. Necromancy is not to be confused with conjuring devils or demons for help.
Necromancy is the seeking of the spirits of the dead.
The spirits are sought because they, being without physical bodies, are no longer limited by the earthly plane. Therefore, it is thought these spirits have access to information of the past and future which is not available to the living. It has been used to help find sunken or buried treasure, and whether or not a person was murdered or died from other causes. The practice of necromancy has been compared by some to modern mediumistic or practiced spiritualism. Many consider it a dangerous and repugnant practice.
