The Fairfield Sanitarium holds a dark secret. If the investigators hope to learn it, they must infiltrate the institute to see what the nefarious conspirators are doing late at night to an innocent patient. No matter how much they discover before they delve into the sanitarium, they will never be prepared for what they find. The horrors from beyond beckon!
The investigators have found that the new Fairfield Sanitarium is most unusual. A missing woman apparently resides there as a patient, undergoing strange treatments. The wealthy heir who finances it visits late at night through a secret underground tunnel. What does it all mean? Deeper the team goes into the dark, the more truth they shall find…at a cost.
The cryptic document, apparently written by Dr. Armitage, references a sanitarium, recently built. The patients and staff have secrets worth investigating. There is also a yacht club in nearby Kingsport, which might have information about this strange case. The investigators begin their work, but even a cursory amount of research is not without its risks.
The investigators have solved the mystery of the book only to find a more vexing document-based enigma. Dr. Henry Armitage has produced a letter, seemingly written by him, that he has no memory of writing. The letter warns of an apocalyptic future for humanity, a disaster that might still be averted. The investigators must determine if it is a hoax, the result of a latent madness in Dr. Armitage, or something supernatural. The references it makes are vague yet still connected to Arkham country. The hunt for the truth is on!
