Game description from the publisher:
The quest for a deeper understanding of reality permeates Written and Bound, the first Asylum Pack from the upcoming "Revelations" cycle for Call of Cthulhu: The Card Game.
While a few sensitive minds shudder at the darker powers they perceive, the bulk of humanity goes about its daily business blissfully unaware of the terrible powers that slowly dig their claws into the very heart of society. Cultists and servitors worship the dread Ancient Ones and seek to extend their influence on earth. Secret societies conduct dark rituals in hidden chambers beneath public notice, criminals buy and sell eldritch relics on the black market, and otherworldly creatures flit through the dimensions, existing beyond the realm of human perception.
Written and Bound introduces 60 new cards (three copies each of 20 cards) that reinforce the power of knowledge and the importance of knowledge seekers in the Call of Cthulhu mythos. New Tome cards, a Library, Criminals, Scientists, Investigators, and Relic Hunters all provide the different factions powerful new ways to use knowledge to manipulate the world to their own ends – or to liberate it from the Ancient One's ever-tightening grasp.
