In Rivers of London: the Roleplaying Game, players take on the roles of newly recruited members of the London Metropolitan Police Service’s special magic branch, aka “the Folly.” You will solve mysteries, catch criminals, and come to grips with the “demi-monde”—those who have been irreversibly changed by magic.

The Rivers of London: the Roleplaying Game core book contains everything you need to start exploring Ben Aaronovitch's magical version of London.

This single, epic volume is for both players and Game Moderators alike! The tome comprises all the rules you need for fully-fledged Rivers of London campaigns.

Build your group of freshly-recruited officers of the Folly with character creation, expand and grow those characters with the complete rules for character advancement, and enjoy extensive advice for running tabletop RPGs—and Rivers of London specifically—provided for the Game Moderator.
