Edit: I've decided to shelve the "Environment as Encounter" Series to do something a bit more conventional. It wasn't turning out the way I wanted. I'm going to go back to regular adventures and revisit the concept at a later date.
The Vengeful Dead
Synopsis: A man is constantly being pursued by zombies which hunt him relentlessly. Even in broad daylight, they go after him. But strangely, they ignore everyone else they encounter.
Background: The man, Alann, is a serial killer. The zombies in question are the reanimated corpses of all of his victims. They pursue him in search of justice for the horrible crimes he committed against them. Despite being walking abominations of life, the zombies are not seeking to kill Alann, but to subdue him and bring him to the proper authorities. The local constabulary knows that there have been a rash of killings, but not who the guilty party is. There is a chance that someone may recognize one or more of the zombies as murder victims, shedding light on why they are chasing Alann.
