Ghosts (sometimes known as a Spirits or Souls), are the spirits of a deceased individual who has return from the dead due to an unfinished goal they failed to accomplish in life. Some ghosts are mischievous, sometimes even villainous, but others are benevolent and helpful.
Ghosts are described as being frightening in appearance, but otherwise harmless. Many have a tendency to haunt the living, whether it be intentionally (as a prank), or unintentionally (for more serious matters).
Unlike other undead creatures, such as vampires, skeletons, mummies, and zombies, ghosts are not physical, rather noncorporal.
Some ghost may present themselves as guardians, though these cases tend to be associated more with Angels. While many ghosts take on the form of humans, others have been described as resembling animals, or even objects, such as trains, cars or ships.
Heroic ghosts tend to differentiate themselves from their more mischievous counterparts by often times contacting the living for help in trying to complete a task that they failed to accomplish in life. In some cases, they will even help the living individual(s) by providing assistance in some form (often times though paranormal means).
