In Arkheim, the "City of Eternal Fog" shrouded in eternal industrial fog, huge brass gears slowly rotate in the heart of the city, and steam pipes are entangled in the steel jungle like giant pythons. People believed in the "Father of Steam" who brought prosperity, but no one knew that what drove the city was not fire, but the hot breath exhaled by an ancient god sleeping deep underground.
Ye Lin, an orphan living in the Lower Gear District, makes a living by repairing precision clocks. He has an innate curse or talent - he can see the "thread of fate" that ordinary people cannot see, and the "rust" attached to it, which represents decay and distortion. He carefully hid this secret until a bizarre "shadow theft" broke his peaceful life.
When strange whispers began to echo in his ears, and when crazy geometric illusions invaded his dreams, Ye Lin was forced to embark on a path to pursue the truth. He discovered that every corner of the city, from the glorious upper domes to the filthy lower waterways, was full of cracks from the abyss. And he himself is the most critical pawn in a grand destiny script that has already been written about the life and death of the world.
Embrace madness and become an apostle of the new god? Or burn out your sanity and become a martyr of the old world? In the symphony of gears and tentacles, entangled in steam and secret words, Ye Lin's choice will determine the final fate of this rusty world.
