Body Jumper

Body Jumpers are evil spirits who were cast out of heaven ages ago by God, and so get back at The Almighty by taking over the flesh of the sinful. Body Jumpers are similar to Possessing Spirits in that they can take over a creature, however they are not bound to a specific person but instead can move from host to host via physical contact.
Body Jumpers are rare, they usually try to keep a low profile (most of the time) but they will not hesitate to harm or even kill their host or anyone else if their life is threatened. 
== Order of Exorcists: ==
The Order of Exorcists and the Body Jumpers have long been at war. The Exorcists are fully aware of the Body Jumpers, their nature and weaknesses, and have succeeded at banishing many of them permanently from this world or trapping them in spectral prisons. 
However, the Body Jumpers are fully aware of the Exorcists, and have been waging a counter-war all their own. They target those close to Exorcists and try to take control of them, using them against their hated Adept enemies.
