Arkham Horror: The Card Game – The Scarlet Keys: Campaign Expansion

A wave of mysterious disappearances spreads through Arkham, erasing people, animals and objects from memory while a few investigators retain the truth. An enigmatic letter claiming shared memory draws investigators into a globe-spanning investigation against a secretive cabal known as the Red Coterie. The expansion provides a non-linear campaign structure: after a fixed prologue and finale, players choose which scenarios to pursue and in what order, with time and the choices made determining which episodes are experienced in a given playthrough. The set adds large-scale campaign content and new scenario cards that expand narrative scope and challenge players to manage limited time while unraveling a sprawling mystery.
