from the designer's blog: The Caverns of None Shall Pass is a gamebook akin to the Fighting Fantasy and Lone Wolf series, or to a lesser extent, the Choose Your Own Adventure series. The game system utilizes a single six-sided die. Your character’s race and skills play an important role in the outcome of numerous challenges. Randomized encounters add replayability. Created in 2013. From the book’s introduction: “A succession of apocalyptic cataclysms vastly altered the surface of Urth. Its strange and fearsome denizens struggle to survive amid acidic lava marshes, crystalline vacuum jungles, and desolate fortress metropolises. You lived among the clone priests of the Sentient Sun Chapel until your unorthodox beliefs led to your exile. Now you must travel to Sanctuary, the city of outcasts, to find a new home. Between you and Sanctuary are the endless caverns of None Shall Pass. Your trek will take you through gleaming alloy tunnels choked with toxic fungi and inhabited by treacherous creatures. Crossing None Shall Pass is a test of your toughness, wits, luck, and desire to survive.”
