We all love to tell stories of a hero triumphing over evil. According to those stories, Mario has defeated Bowser and rescued the princess again and again, without fail. But anyone who has actually played the platformers those stories are based on knows that most runs don’t end in victory for the hero. It usually takes many tries, and many Mario lives, before one finally makes it to the end.
This is a story of the failed attempts: the countless Marios who fell in bottomless pits, whose heroic journeys were never finished. Really, this is the story of just a few of those fallen Marios, trapped in a forgotten dimension of darkness, faced with the end of their own stories, and wondering if any faint hope might remain for themselves, or for the worlds they left behind.

His pinky tapped against his cheek, and he crossed his wrists above his chest before touching her belly again. If I loved her… His hands shook as he signed, and she could see the desperation growing in his face. He held up four fingers and tapped his index against his chin. I would speak.
