In the world of Embri, one will find the ordinary and the extraordinary. The two superior species on the planet are human beings and revenants, a type of creature that manifests as a walking and sentient skeleton. Some are good; some are bad, but many have a story to tell.

Benjamin Cox lives in a lower-middle-class neighborhood in the town of Delgerryburg. After accidentally breaking a window, he is grounded. Tired of his parents and their rules, he runs away, stopping at the train station at the other end of town. There, he meets a mysterious station master. While waiting for his train, he encounters a beautiful luxury steam engine and is determined to board. What Benjamin does not realize is that this train could give him one hell of a ride.
