The spirit of a person who died violently or left a task unfulfilled in its lifetime. These spirits are fated to haunt the location of their death forever unless they are somehow laid to rest (by either salting and burning the spirit’s bodily remains, avenging its death, giving the remains a proper burial, or exorcism). Sometimes, a ghost is visible, but most of the time it isn’t. However, the spirit is able to affect the material world and may be sensed by sensitive individuals. Many ghosts can become quite malicious, because their predicament has either driven them insane or they desire revenge for wrongs that were done to them in their lifetime. It is able to pass through walls, drain the lifeforce of a living being with a touch, or to create poltergeist effects.
