Strange disappearances haunt the city of Arkham, Massachusetts. With each object, building, or person that vanishes, they are erased not just from physical existence, but from history and memory as well. Only a select few investigators remember those that vanished—or so they believe. Before long, the mystery unravels into an international conspiracy, and our wary investigators find themselves recruited by a shadowy government agency whose sole purpose is the collection and research of paradimensional implements they call “Keys.” However, they aren’t the only ones searching for them…

This pair of separate-but-related expansions take the game around the world, and we mean that literally! Six new investigators from The Scarlet Keys Investigator Expansion embark on a globetrotting adventure in The Scarlet Keys Campaign Expansion. Just like with Edge of the Earth, you will find only player cards in the Investigator Expansion and only scenario cards within the Campaign Expansion. Whether you want one expansion or both, the world of Arkham Horror just got bigger!
