Above the giant city "Rusty Bell City" built of steam and bones, there is a thick gray-black fog that permeates the sky all year round. The huge brass bell tower is like a tombstone of a god, overlooking the mechanical creation driven by Aetherium (etheric crystal) lingering on.
Every corner of the city-state echoed with the whisper of gears biting, as if it was the breathing of this mechanical behemoth. However, no one knows that beneath this never-ending rhythm lies an ancient will from beyond the sea of stars.
Su Yelin, the apprentice of the clockkeeper, is a mortal chosen by fate. He can hear the "singing" deep in the machine that should not exist. This song is both a gift and a curse, leading him to glimpse the reality of the world - behind the precise gears and steam pipes, there is twisted flesh and crazy geometry.
When the fateful bell rang, Su Yelin was forced to embark on a road of no return. In order to resist the preset fate of the "container", he must constantly accept the forbidden knowledge that can drive anyone crazy, reshape his body with brass and gears, and control the power of the abyss with the heart of a mortal.
Every strengthening is a farewell to "people". Every choice is swinging on the tightrope of "redemption" and "destruction".
This is a tragic song about a mortal "gear heart" trying to move the entire chessboard of fate in a cold and desperate universe. When the truth of the world is peeled away, when the steam dissipates, will he be crowned a new god, or will he become a sacrifice for the return of the Old Ones?
