By the late 19th century, Great Britain had risen to become the most powerful empire in history. Yet, beneath this prosperity lay a rigid economic hierarchy that determined a person's worth strictly by their status and wealth. Unsurprisingly, this system privileged the aristocracy at the top, making it impossible for the working class to climb the social ladder. William James Moriarty, the second son of the Moriarty family, lives as a typical nobleman while also serving as a consultant for ordinary people, helping them solve their problems. However, deep within him burns a desire to dismantle the corrupt structure that dominates British society and those who profit from it. Together with his brothers Albert and Louis, William is willing to do whatever it takes to change the filthy world he inhabits—even if it means shedding blood.
