In Call of Cthulhu: The Card Game - Spawn of Madness, chaos explodes through a series of powerful events and support cards. "The Sleeper Awakens!" for the Cthulhu faction will clear the board of characters while Yog-Sothoth's "Revelation of the Spheres" will steal characters before opponents have a chance to play them. Madness, Disasters, Monsters, and Servitors lurk in Spawn of Madness!
Spawn of Madness first appeared as an Asylum pack when that game was being published in a CCG format. In 2011, Fantasy Flight Games revised Spawn of Madness to fit its Living Card Game format, with three copies each of twenty different cards. The card text has been updated to reflect the most recent FAQ and errata.
