An All-New Case File for Rivers of London!
Foulness in the Fog is a stand-alone scenario for Rivers of London: the Roleplaying Game based on the novels by Ben Aaronovitch. This 46 page scenario can be used as a one shot, or played as part of a larger, ongoing, Rivers of London campaign.
There’s Something Rotten in the District of Hammersmith...
Saturday 20th August, 2016: a boring afternoon cataloguing the Folly’s mundane library is thankfully interrupted by a call from Hammersmith Police Station. Three people were found unconscious in the street, and the first responding officer suspects this is a Falcon case.
Can you figure out what happened to the casualties? And what does their predicament have to do with a strange fog seen in the area at the time of their collapse?
