Necromancy is a form of magic involving communication with the deceased—either by summoning their spirit as an apparition or raising them bodily—for the purpose of divination, imparting the means to foretell future events or discover hidden knowledge. The term may sometimes be used in a more general sense to refer to black magic or witchcraft.
