Behemoths of steam gnaw at the sky, and the glow of magic burrows deep into the earth. This is an era that is torn apart, and it is also an epic that is reborn from the ashes.
In a world where phlogiston and magic are at odds with each other, Serafina Wilder carries a deadly secret. She is a rare "double-sensory person" who is born with the ability to sense and guide these two opposing forces at the same time. This is both a curse and a trump card for her survival as a mechanic in Rusty Iron Town.
However, the peaceful life was completely shattered by a "music box" from ancient ruins. This creation, which contains the secret of the perfect symbiosis of technology and magic, draws her into the huge whirlpool of the empire's new aristocracy and the ancient mage family's struggle for world dominance.
This is a majestic imagination that combines the hard-core romance of steampunk and epic fantasy, and is a stellar epic about the survival of civilization, class revolution and self-awakening.
