Where do you go for answers when your world is tilting into madness? The answer: Paris. A Phantom of Truth is the third Mythos Pack in "The Path to Carcosa" cycle for Arkham Horror: The Card Game. As you investigate the mysteries behind The King in Yellow, the Mythos Pack's new scenario introduces a new set of clues, along with supernatural terrors that play upon your growing Doubt or Conviction. Amid these horrors, you'll find twenty-two new player cards (two copies each of eleven different cards) to help you stay grounded and pursue the truth.
