1890. At the height of the Industrial Revolution, the Great Empire is about to take delivery of many secret crates from its colonies. These crates contain all the Emperor needs to strengthen his rule on the Empire: steel, coal, ore, and above all: gold! For security reasons, the Emperor himself has hand-picked the crew of the Nostria, one of the armoured zeppelins of the imperial fleet. However, neighbouring nations are organizing the resistance, and traitors are secretly boarding the airship to thwart the Emperor's plans.
