London, 1851. Strange forces – faerie, magic, and the more bizarre inventions of science, are everywhere, and barely secret. The infamous Kerberos Club is both a shelter for those touched by the Strangeness, and is at the same time dedicated to protecting Queen and Country from the threats offered by the Strange.
It is the time of the Great Exhibition, held in the newly built Crystal Palace. The heroes of the Kerberos Club have received complimentary tickets for the opening day. All manner of exotic curiosities and wonders are on display, and visitors have come from far and wide.
Then events occur requiring the intervention of the heroes, and their peculiar talents.
