Death is not the end. When the shell ceases to live, the soul is released. Some go to eternal paradise, others find damnation, doomed to forever suffer in agony. However, there are those who refuse to move on. It could be that they fear judgment, or perhaps they have unfinished business. Either way, they stay behind using the emotions and energy of humans to keep their souls on earth.
That feeling of someone watching, an inexplicable yet overwhelming sadness, a sudden cold chill, the strong need to flee in terror when an inanimate object seems to move on its own. A lost soul could be nearby. Or possibly another being. It could be a soul collector.
When a soul faces judgment but hasn't done enough good to go to heaven or enough bad to go to hell, they are given an important job back on earth. These are the soul collectors. Some of them are fortunate enough to keep their bodies, but it all depends on how they died. The soul collectors who perished in such a way that their bodies were too badly damaged are assigned new freshly deceased shells. Though the body is only a vessel to carry them through the physical realm. In order to collect a soul, they must project.
Projection is the act of allowing one's soul to leave the body and move freely through the astral plane. This also allows them to battle and capture the lost spirits haunting this world. Unfortunately, a body left unattended is vulnerable to attack and even possession. A projection can pull an unwelcome specter from a shell, but if the shell is destroyed, the soul collector becomes a lost spirit themselves.
Projections, like souls, don't have discernible features unless whoever is viewing the apparition knows what they look like in their bodies. At that point, the brain assigns those same features to the projection or soul. Also, knowing how a bounty died will place images of those injuries on the specter. It's just a trick of the mind to help identify familiar ghostly forms. Otherwise, projections or souls just look like glowing ambiguous humanly forms.
Projections, like lost souls, can be beaten. At that point, souls have the ability to absorb them and become more powerful. If the projection isn't absorbed, it can return to its body once it has awoken or has been carried there by another projection or soul.
Soul collectors are just like humans except for one key factor; their body was once dead and with each bounty obtained, they can keep it from decaying. The more powerful the collected soul, the longer it can sustain the shell. If the soul collector doesn't do their job, they will rot until they can't move any longer. Then they are just a spirit trapped in a pile of reeking meat.
All around the world, groups of soul collectors are split into sections and assigned an angel who informs each of them about a bounty. Because of humans' free will, the heavenly beings cannot track where the fugitive spirits are, nor can they apprehend them. All the angels can do is give the collectors a name and the time of death. It's up to the bounty hunter to do the rest. This often calls for a bit of investigation, and time is a factor. The longer a specter goes uncollected, the more powerful they can become. Some souls avoid capture for so long, they gain the ability to absorb projections and other spirits, thus becoming stronger apparitions.
For the most part, soul collectors don't have a choice about existence, but they do have a choice about which side they collect for. Everyone starts the job with an angel as an informant, but if they so choose, they can collect for the Fallen ones. Sure, demons are evil, but they still have to abide by the same rules as the angels. The difference is they offer great perks: a different set of projection abilities, wealth, the satisfaction of their carnal desires, and any other want the collector has is fulfilled. There is a catch; if and when the collector meets his or her end, they are sentenced to an eternity under the rule of Lucifer. Bounty hunting for the Kingdom of Heaven will eventually earn a collector a place in paradise at the time of their demise, but life on earth won't be easy for them. They still need a job to afford food, shelter, and whatever else they need.
A Bounty of Souls offers an endless amount of stories and adventures. Although this book is full of rules, the only limit is the imagination of the players and the Narrator. So gather around, and prepare to participate in the ultimate struggle for good and evil.
