Isaac Robbins is a young man who has spent his entire life in the Commons District of Sanctum, a district analogous to Victorian Era Germany. He was raised an orphan until the age of fourteen when he was sold to the Ellwood Quarry. Through a strange series of events, Isaac comes to know Professor Bastion Kaufman, a professor of archaeology and even finds himself among a group of radicals known as the Red Dove Society that work towards the goal of overthrowing the royal families and bringing about a political revolution in the city. With the new allies and enemies Isaac makes, he begins to uncover something truly sinister looming over the city of Sanctum.
