Ghosts

Ghosts are the disembodied spirits of a person or animal that is incapable of moving beyond the mortal world into the afterlife. There are many reasons why a ghost might linger behind. Some stay in order to complete and unfulfilled task. More malign spirits may remain behind in order to mete out vengeance or some other dark pathos against members of the living. Ghosts are usually invisible and are capable of only minimal physical interaction with the corporeal world, though some, such as poltergeists, are capable of making physical contact with the world of the living. Some ghosts are even capable of maintaining some form of visual perception to living humans, though their appearances may vary depending upon their personality.
