Greed of the Great Pumpkin: Learn to Play CAIN (1-Shot)

About the adventure

You are an Exorcist, an individual graced with psychic powers manifested from the darkest depths of the collective psyche. Your powers, and your self, have been honed by CAIN, an extra-governmental agency with international reach. Under CAIN's careful watch you have been transformed into a weapon. Be thankful. Those graced with powers who are not subjected to CAIN's strict regime more often than not find their powers manifesting as Sins. Sins are living psychic entities birthed of trauma, tragedy, and pain. Most ordinary humans are blind to these manifestations of humanities failures, but you do not have that luxury. Your life has been devoted to the hunt and destruction of Sins. Today, October 31st, a new Sin has emerged. 1 hr, 12 mins ago, witnesses began reporting a group of armed adult humans in grotesque masks "trick or treating" at gunpoint. They arrived at the door to a residential neighborhood in a group of four, pointed a gun at the occupant and demanded candy. Any resistance to their demand was met with immediate and unrestrained violence. If given sufficient candy, the individuals left for the next house. If they were given insufficient candy, they retaliated with immediate and unrestrained violence. Several squads with this modus operandi have been identified already, and they seem to be acting in coordinated raids. Behavioral analysis suggests they are under the influence of a Toad, but no one with sufficient grace to maintain memories of the Sin has reported on it. Toads are Sins born of extreme material want, and are known for acquiring material wealth. That this toad is focused on candy is anomalous, but make no mistake the Toad is dangerous. There has been one fatality already, and we have not sighted the beast itself. Your task is simple. You will be dispatched to the area. Investigate the crimes, find the Sin, destroy it. Once deployed you will be on your own. No mortal authority recognizes CAIN, but your authority exceeds the mortal. Execute CAIN doctrine. Show no mercy.
