The great brass pipes of New Britannia's industrial district sang their familiar morning song, a symphony of steam and pressure that had awakened Engineer First Class Arabella Fairfax every day for the past three years. She stood at her workshop window, watching the dirigibles drift between the towering smokestacks like mechanical whales navigating an urban ocean. The year was 1887, but this was not the 1887 that history books would remember. This was a world where steam had conquered more than just locomotives and factories.
Arabella's fingers traced the intricate gears of her latest invention, a mechanical chronometer that could predict steam pressure fluctuations across the entire city's network. Her workshop, perched high in the Clock Tower District, overlooked the sprawling metropolis of New Britannia, where brass and copper gleamed alongside traditional stone and brick. Steam-powered automatons walked the streets beside horse-drawn carriages, and overhead, the sky lanes buzzed with personal flying machines powered by compressed air and ingenuity.
