The world of Contagion is a dark and terrifying place. On the surface, it looks much like the world you and I live in. Just beneath that surface, in the shadows, rages an ancient conflict between supernatural factions who all seek dominion over the Earth and control over the souls of humanity. A new type of creature has been born from the escalated conflicts of the war. Angels caught in the midst of a fall and enslaved through blasphemous rituals are being recruited by a faction of desperate Arcanists. These enslaved angels are called the chabash.
