In the steam city "Aittelburg" where absolute rationality and mechanical order are the highest creed, clock master Elias Thorne was appointed by the supreme governor to build the "heart" of the city - a giant precision clock "Cronos Core" that can synchronize the work and rest of all machines and residents in the city. However, there is a pain buried deep in Elias's heart that cannot be erased by order: his late wife who was "calibrated" by playing "disordered" music. Between the cold gears and the precise drawings, he decided to implement a secret rebellious plan - to quietly implant his wife's memory and melody into this mechanical heart like an indelible program. He wants this city that has forgotten emotions to hear the whispers of the soul again.
