In The Pallid Mask scenario, you and your fellow investigators will enter these tunnels in search of a stranger whom you believe must be connected to the events surrounding the performance of The King in Yellow at the Ward Theatre in Arkham. The scenario from The Pallid Mask utilizes the game's locations in a novel way, bringing them into play only as you travel through them, and arranging them in a constantly shifting and unpredictable fashion. Each new step through these labyrinths could be your last.
