The last airborne citadel, Gearhold, runs on steam and leftover magic crystals. It is split into the floating Upper City and the sunless Lower City, a dumping ground of refuse. On a stormy, thunder-lashed night, a burning aristocratic airship crashes into the junkyards of the Lower City. Karen, a reclusive mechanic, stumbles upon a dying young girl named Ella. To his horror, a glow seeps from a rupture on her chest—the cerulean radiance of a long-extinct Living Origin Magic Crystal. Before he can process what he sees, mechanical hounds dispatched by Lord Veyne, who schemes to seize power, surround the scene. Drawing on the instincts forged during his days as an elite Holy Guardian, Karen detonates the steam pipelines. He flees into the underground black market, dragging this glowing enigma along with him.
