Necromancy

Necromancy is the practice of magic involving communication with the dead – either by summoning their spirits as apparitions, visions or raising them bodily – for the purpose of divination, imparting the means to foretell future events, discover hidden knowledge, to bring someone back from the dead, or to use the dead as a weapon. Sometimes referred to as "Death Magic", the term may also sometimes be used in a more general sense to refer to black magic or witchcraft.
