Welcome to late 19th century London. In this time of rapid technological and societal change the old world is pushing back. Spirts are no longer resting easy in their graves, beasts have begun clawing up from the depths, and the dark tendrils of madness machinate evil. Only a few brave souls stand against these forces. Sword, gun, spellbook, and cross work together in the shadows to keep the city, and indeed the world, safe.
