When an injury at work forces Hongjoong to hunt down the elusive mechanist capable of outfitting him with a new limb and- unbeknownst to both of them- unlocking the secrets to a treasured design of his own, a series of undercover meetings in the dark becomes a quest to unite eight boys with a single dream.

Or, Joseon's new Ministry of Technology pushes the nation relentlessly into a steam-powered future. It's adapt or face the consequences, but being left behind costs far more than even Hongjoong could have predicted.
