2.8   DYBBUK Sometime the soul resists the pull of the afterlife.   The evil spirit fights against the unrelenting draw of Tartarus, knowing that only pain and suffering await it in the hereafter.  But once a soul has been released from its body, it cannot return to the dead flesh.   Instead, it latches on to a nearby living being, piggybacking on the soul that already resides there.   Such a sprit is known as a Dybbuk. A Dybbuk, literally meaning "a clinging soul", is a rarity.   The conditions must be just right for it to occur.  Firstly, the released soul must have led an exceedingly evil existence.  Secondly, there must be a child of clay host nearby, one who is very ill or is at extremely diminished capacity. As the evil soul leaves its dead husk, it feels the presence of a human body that cannot resist its intrusion.  It rushes toward the host burrowing itself into the living matter. But the human body is not designed to hold two souls.  Conflict arises between the two immortal spirits, and in the end a type of melding occurs. This melding will, over time, cause the host soul to become warped by the intruder.  The child of clay will begin to taken on the attributes and desires of the Dybbuk.  Were these intruder souls benevolent spirits then all might be well, but their evil nature will inevitably lead the child of clay down a path of depravity and destruction. Once a soul becomes a dybbuk, psychopomps are no longer able to use their sense death force to detect them.  In fact, these vile spirits are extraordinarily hard to find.   Even if there are hints that a dybbuk has invaded a child of clay, there is no way to know for sure. Dybbuk possession and demonic possession should not be confused.  They are completely different occurrences.   The dybbuk does not subvert the original soul as it grows strong (the way a demon might).   Rather it corrupts the host soul, which remains conscious and in control at all time.   Likewise, the right of exorcism that many faith proclaim will have no effect on these spirits, though many faiths have separate rituals that deal with this issue.   Children of fire can attempt to use Purest Spirit, one of the forces of protection, to expel the dybbuk, but such use is much harder, and the user's contested roll will be reduced by five.
