Ghost

Ghosts are the undead souls of humans,animals, and supernaturals.

The Afterlife
When any living human, animal, or supernatural dies they become a ghost and usually pass on to the netherworld. However, sometimes, ghosts can linger around the mortal plane after death.

Earthwalkers
Earthwalkers are ghosts whose souls are still tethered to the mortal plane. These ghosts can live their unlife among humans

Appearance
Ghosts keep their physical form from when they died. However, they are colorful and transparent. Any clothes a ghost wears become ghostly and transparent as well. Ghosts can take on the appearance of a human with a Ghost Vaccine.
