London. The winter of 1952. A mysterious and deadly Smog has enveloped the city leaving it in a panic. Crime is up, hospitals are overrun, businesses are closed and all travel is shut down.

It's the perfect cover for Dorothy Schafer to carry out her revenge plan against The Circle-an agency of mages and witches sworn to protect London from crime and disease since the Middle Ages.

Under The Circle's rules, Dorothy's husband, John, was unjustly found guilty of murder and the punishment was swift: a Demon was summoned and dragged him straight to Hell. To get vengeance for her husband, Dorothy undertakes a quest to craft a blade for battle against The Circle...and Hell itself.
