In the giant city of Asrium built of steam and brass, every precise meshing of gears maintains the memories and thoughts of millions of citizens. Kyle, a young gear technician, is the most loyal guardian of this city of order.
However, when a "whisper" comes from the depths of the "great axis" that maintains everything, a plague of memory begins to spread. Family members become strangers, history begins to fade, and Kyle's world collapses. He reported it to the higher-ups, but received silence and warning.
In order to pursue the truth, he was forced to step into the darkest underbelly of the city and join forces with the exiled mysterious "Memory Weaver" Elari. They discovered that this city of perfect order was built on a cruel lie. What they worship is a cage; what they firmly believe in is a scam.
When the truth of the entire world is about to rust and collapse, Kyle must make a choice: maintain the hypocritical and stable order, or ring the freedom bell that may bring destruction? Every choice he makes will redefine the weight of memory and existence.
