After your fateful investigation in Union and Disillusion, the state of the city continues to decay. Breaches in reality begin to rip through the fabric of the Earth, and a faint melody of discordant pipes can be heard throughout the streets of Arkham. In the Clutches of Chaos, doom does not accrue at the usual rate. Instead, breaches are made at various locations, marked by resource tokens. When enough breaches have been made a single location, an incursion occurs. Your goal is to prevent incursions by removing the breaches that cause them, but this can only be done by activating the action abilities on each location.
