"This is the thing that troubles me, for I cannot forget Carcosa where black stars hang in the heavens; where the shadows of men's thoughts lengthen in the afternoon, when the twin suns sink into the lake of Hali; and my mind will bear for ever the memory of the Pallid Mask."
     –Robert W. Chambers, The King in Yellow

Echoes of the Past is the first Mythos Pack in The Path to Carcosa cycle for Arkham Horror: The Card Game.

The King in Yellow has come to Arkham, you caught the performance, and now you find yourself drawn into the maddening web of powerful forces and sinister event that seems to surround the mysterious play. So how do you proceed? Where do you continue your investigations? How you do hold onto the tattered threads of your limited sanity? If there are ties between the play and Arkham, there's one place where you might uncover them—the Arkham Historical Society, a landmark building that holds age-old secrets even its curator doesn’t know…

Even as it introduces a new scenario through which you can explore the Society’s hidden secrets—and the many terrors with which they are associated—Echoes of the Past introduces a wealth of player cards driven by two major themes that allow you to refine your investigator’s practiced Talent and Composure.

This is not a standalone product. It requires the Arkham Horror: The Card Game Core Set and The Path to Carcosa deluxe expansion to play.
