Arkham Horror Roleplaying Game Core Rulebook

In the heart of 1920s New England, nestled among the rolling hills of the Miskatonic River Valley, lies Arkham, Massachusetts. Caught in the midst of the tides of change and progress, the city struggles to shrug off the myths of its past and step into a shining future. But too many of those myths have a kernel of truth at their core, and the eldritch horrors that haunt Arkham’s past still lurk just beyond the threshold of our understanding. Nothing can stand against the monsters that stalk the darkness... except you.
