After some sort of horrible apocalypse, the world is left with only one type of energy: steam. There are also left two kinds of people: those who can afford to buy the factories and run them, and those who can't. Once such family is the Vaughn family. Lord Vaugh and his wife are blessed with only one child, a daughter, Spencer. She is the apple of her fathers eye, and he only wanted what was best for his little princess.

Jedediah Guerin, on the other hand, was nothing more than a common thief. His talents included stealing and running from the law. He wasn't exactly the type to be stuck in a factory all day, working under the whip of an overseer. However, one day Jedediah decided to try and steal from Lord Vaughn. He took pity on the young man and decided to offer him a choice: jail or become personal body guard to his daughter. As Jedediah wasn't one for a job, he chose jail. That is, until he was beaten within an inch of his life.

Again, Lord Vaughn approached him, offering him the same deal. This time, Jedediah took it. He was thrown into work with wounds that would still bleed, a broken body, but a strong soul. If this was his fate, he would do whatever he could to protect the girl. Even if it meant his own life.
