After escaping the decaying inner world Segis finds himself in the real world; a place he knows nothing about. He sets out to find Stal's whereabouts with the help of a mysterious girl named Delphy. The problem is that the world is nothing like the world he is used to live in: no sky, no dirt, no stars; just endless corridors, chambers and cities completely cut off from each other where it is forbidden to go outside. The truth behind the Magna Maquina is a secret kept by the ages, long since forgotten by humankind and that without him knowing is deeply tied to his fate.
