Necromancers are individuals who practice necromancy, a form of magic that involves communicating with the dead. They are often depicted in folklore and fantasy as having the ability to summon spirits or raise the deceased from their graves. This practice is typically associated with dark or forbidden arts, and necromancers are frequently portrayed as villains in stories. In various cultures, necromancers may be linked to rituals or ceremonies aimed at gaining knowledge from the afterlife. They often appear in literature, games, and movies, where they wield powers that can manipulate life and death. Common themes include the use of skeletons, zombies, or ghosts as part of their magical practices.
