Dr Quinn created a Sustainable medical life support called “Quinn-sin” through the wisdom of Azazel . This Quinn-sin retains a ghost to be visible in the physical realm, it will  help the dead whom did not complete their graph of existence to co-exist with their love once again. The said Quinn-sin can only be preserve through human blood and then injected to any shadowed Ghost. So he choses to eject it into his two children Jesse and Jason. But then the unrighteous ghost; those who died with wickedness, has come after them to have a taste of their blood to re-exist and rewrite their wrongs. This will bring the defilement of the aged Boundaries between the spirit realm and the earth realm, as it was against the will of God for the secret mysteries of the world of the dead to be made know to mere mortal before their death. Michael had warn Maureen and other righteous fellows to war against Azazel and his co-hunts in other to prevent the defilement of the spirit boundary so that the recompense of the Just will not be jeopardized. Welcome to the ghost world.
