About the game
Years ago, a mysterious structure known as the "Jail" appeared out of nowhere and dragged an entire city deep underground. Sitting 666 meters below the surface, this sealed, living prison ruled over unsettling beings known as the "Marchen." Trapped within its walls, young Jack endured constant suffering. Idea Factory developed this RPG blending adventure and strategy elements, and Ghostlight LTD published it in 2018.
