Game description from the publisher:
Some secrets should never be brought to light... Murder, madness, and terrible realities haunt the pages of Abdul Alhazred's horrifying tome, the dread Necronomicon.
The "Revelations" cycle for Call of Cthulhu: The Card Game moves to its penultimate Asylum Pack, The Unspeakable Pages. The game's rival factions delve into four versions of the Necronomicon, and a host of new characters seek to gain power from its secrets. Meanwhile, the ignorant masses continue their mundane routines, blissfully unaware of the Ancient Ones, monsters, and magicians who seek this dark knowledge to manipulate reality itself. While the key to the fate of the world may lie in Abdul Alhazred's dread tome, the "Revelations" cycle moves toward its climactic finale. Sixty new cards (three copies each of twenty different cards) deepen the game's eerie Lovecraftian horror as cultists, lunatics, and investigators all delve into The Unspeakable Pages!
