The Unspeakable Oath is the second Mythos Pack in The Path to Carcosa
cycle for Arkham Horror: The Card Game, and it carries you deep into
the belly of Arkham’s asylum. You’ll find yourself behind locked doors,
wracked by Doubt, and surrounded by Lunatics. And, still, you’ll catch
hints of deeper and darker secrets. And while its scenario continues
and deepens the game’s exploration of the mystical realms between the
traditional roleplaying and card game experiences, its twenty-four player
cards (two copies each of twelve different cards) provide you access to a
number of wealthy Patrons and allow you to “learn” from your mistakes.
