The silver-headed city of Amnibus is bustling with life. Airships decorated with Egyptian symbols fly past the emerald domes of the Cathedral of Osiris, the gendarmerie catches criminals, merchants sell mechanical models and more, barbers shave their beards. In general, everything is as always - and no one remembers that once upon a time the city was called St. Petersburg. Before Egypt returned to the world. But one visit of a certain gentleman to the barber Alexis Osmius, whose hands are more like steel rollers, begins a series of life-altering events and reveals a lot of new things. For starters, it reveals that soon people will be fired up with a new idea. And along with this, the skies of Amnibus will also burn.
