Game description from the publisher:
That Which Consumes is the sixth and final exciting Asylum Pack in The Rituals of the Order expansion cycle for Call of Cthulhu: The Card Game. It introduces three copies each of 20 never-before-seen cards to the vibrant Call of Cthulhu metagame, expanding the deck-building options of all factions, including the new Order of the Silver Twilight faction.
The sudden surprise of the ground giving way is the theme of That Which Consumes, in which a variety of new event and support cards will be introduced into the arsenal of each faction. From Hastur's Final Note which destroys all insane characters, to Yog-Sothoth's A Gift of Knowledge which trades wounds for success tokens, That Which Consumes will keep your opponents guessing what explosive event will come next.
With the element of surprise looming dangerously, no one is safe from That Which Consumes!
