Your investigation into the mysterious play The King in Yellow has led you through a maddening series of events, from the darkest corners of Arkham Historical Society, to twisted halls of the asylum, and even the catacombs of Paris.

In the distance, a murky lake reflects the glare of two suns. This is Carcosa—the realm of madness in the stars, where Hastur reigns supreme.
