The late 19th century saw Great Britain become the world's most powerful empire, but its economic hierarchy remains inflexible and still values status and wealth over all else. This leads to a social structure that heavily favors the aristocracy at the top and leaves little room for social mobility for the working class. William James Moriarty, a typical noble and second son of the Moriarty family, works as a consultant to the common folk, aiding them in solving their problems. However, he is also driven by a fervent desire to dismantle the broken societal structure that currently dominates British society. Together with his brothers Albert and Louis, William is determined to fully overhaul their stagnant world, even if it requires extreme measures such as bloodshed.
