Spring, 1776. Boston is free. The Second Continental Congress works to create a new nation. But as they debate, shadowy forces prepare to strike back.
Welcome to Philadelphia.
William Penn's model city is one of the richest in the Thirteen Colonies. It stands at the heart of the Revolution. Home to book shops, thinkers, and a growing intellectual class, the city hides those with knowledge of a more questionable nature. With the leadership of the Revolution here, the city is awash with plots, and dangers. It is here that many plots are about to meet - and it is far from certain who will stand the winner.
The Philadelphia Affair is the second volume in the epic Flames of Freedom campaign for Colonial Gothic. In this book you will find our guide to the great city and a ready-to-play adventure which takes up the Heroes' story after the events of Boston Besieged. As Congress works, the Heroes scour the City of Brotherly Love for a friend's missing son. Not all is as it appears, and soon their simple assignment turns into a race against time - to prevent a tragedy that could kill the American independence before it has even begun.
Written by Richard Iorio II and maps by Gabriel Brouillard (Colonial Gothic: New France and Under Pashuvanam's Lush), The Philadelphia Affair is your guide to the colonies most important city.
