The city of Edgewater is under attack, though few realize it. Most just assume the rats and other vermin in the sewers have started spreading a new form of plague. They’re partially right – rats are spreading a virulent new disease throughout the city. But the city’s sewer system holds many secrets, for those willing to plump their filthy depths. More is at play than just some filthy rats and a new strain of disease. Edgewater’s folly is a 7th level Pathfinder Roleplaying Game adventure of heroic proportions.
