In the Eternal Night City driven by ether steam, huge brass gears slowly rotate on the track in the sky, and the cold metal moon shines on the Gothic spiers shrouded in thick fog and soot. This was a glorious era when humans used machinery and alchemy to move the world and thought they were the masters of all things.
However, beneath the surface of prosperity lies a long-forgotten taboo truth - the "source of spirituality" that drives the entire civilization is nothing but the unconscious breath of ancient gods sleeping in the abyss of time and space. Every technological leap forward by mankind and every deep absorption of spiritual energy push the entire world to the edge of madness and distortion.
Ye Linchen, a relic restorer living in Xiacheng District, was born with the ability to hear whispers from the other side of the starry sky. This was seen as an ominous "astropathology," a curse he had to hide for the rest of his life and a fate he couldn't escape. He repairs old objects that carry history and secrets, and just wants to live an ordinary life in this cold mechanical city.
Until a "star snail" from the sunken fleet was delivered to his workbench. When he tried to repair this relic that should not exist, he glimpsed the horrific history submerged in the long river of time, and awakened the ancient contract hidden deep in the bloodline.
The gears of fate are turning suddenly at this moment. The judges of the church, the alchemists who search for the truth, the aberrant monsters lurking in the shadows, and the secret cults that follow the guidance of the stars... All the forces stirred up the situation because of him.
