The Avenging Angel

In the city of Ashgrove there exists many social ills which ravage the rest of the world. Poverty is skyrocketing, crime is through the roof, the poor get poorer as the rich grow more powerful. Most puzzlingly of all, women are disappearing off the streets seemingly at random. Gangs control most of the city, with the police and other state institutions either complicit or apathetic to the damage being caused. On the surface life can sometimes appears normal, but underneath there is rot.
Beyond this danger however something even more sinister is occurring. A war between Demons and Angels which has been carried out under humanities nose for millennia has spilled out onto the streets.
