This slow-burn psychological horror campaign focuses on investigation and roleplay as players uncover the dark secrets of Berghaus Weisshorn through daily interactions with patients and staff. The central mystery revolves around Dr. Zimmer's experimental treatments and their connection to something ancient sleeping within the mountain—are patients being cured or transformed into something inhuman? Players will navigate the rigid sanatorium routine while secretly investigating shared dreams among patients, unexplained architectural impossibilities, staff disappearances, and the facility's true purpose. Exploration paths include building alliances with other patients to share information, infiltrating restricted medical areas, researching the mountain's pre-sanatorium history, deciphering the symbolism in patient artwork and writings, and ultimately deciding whether to expose the truth, attempt escape, or submit to the mysterious cure. Success depends on careful observation, managing your cover identity, and making difficult moral choices as the line between healing and horror becomes increasingly blurred, with multiple possible endings ranging from heroic escape to willing transformation.
