After your fateful investigation in Union and Disillusion, the state of the city is still decaying. Breaches in reality start to rip through the fabric of the Earth, and a faint melody of discordant pipes can be heard in the streets of Arkham. Scared citizens have sealed themselves in their homes, yet you continue to patrol the streets, desperate for a solution to end the chaos. The 5th Mythos Pack in The Circle Undone cycle for Arkham Horror: The Card Game has 60 new cards to expand your adventures in the Arkham Horror Files universe. In the Clutches of Chaos, doom does not arise at the usual rate. Instead, breaches are made at multiple locations, marked by resource tokens. When enough breaches have been made in a single location, an attack occurs. Bring some new allies and spells to your arsenal.
