The Unliving

"Oh, I hate the undead, running around all dead but alive."
--Grim Reaper (from Billy & Mandy) stating his hatred for the undead.
The Unliving (also called the Undead, Zombies, Ghosts, Spirits, the Dead, Demons, etc.) are beings who have entered their "Negative Limbo" phase and refuse to go to Heaven or Hell and refuse to leave the world and sometimes their own bodies.
==Zombies==
Zombies are made when a being makes a spiritual chain that links it's soul to it's body.  This makes it possible for the being to return as a zombie and eat everyone's brains.  Usually the chain is located on the head (and usllay it IS the head) and therefore, shooting off the head breaks the link and kills the body whil sending the soul to Hell for it's use of dark magic while it was alive.
==Ghosts and Spirits==
Ghosts and Spirits are usually made when a being makes a spiritual chain that links it's soul to a fixed location in the universe.  This makes it possible for a spirit to manifest in certain locations.  Usually exorcisms break the chain and send the spirit to Hell for it's use of black magic while it was alive.
==Demons==
Demons are usually made when spirits of beings make a deal with the Devil and gain a new, more powerful body.  this means that they can do even more harm as an Unliving being than as a Living being.  Usually, as with spirits, exorcisms break the temporary chain between the soul and the demon body, sending the soul to Hell where it belongs and destroying the demon body.
