World
Aero Empire is set in a world where the majority of the landmass lies below a thick layer of clouds called the “Twilisphere.” Scarce, tall mountains peak through the Twilisphere, creating what little landmass lies above. Below the Twilisphere, the climate is not earth-like, and cannot support life as we know it. The Twilisphere is really a permanent artifact of the boundary between the two different climates of the planet – the alien one below, and the earth-like one above. Because of this, the Twilisphere is perpetually turbulent and stormy, with frequent lighting strikes. Venturing into the Twilisphere is akin to committing suicide; even if you survive the Twilisphere itself, the inhabitable climate below would kill a person in a matter of minutes.
In this world, all human life evolved on the tops of mountains above the Twilisphere. Tribes formed on the different mountaintops, isolated and without knowledge or concern for the other tribes. Even as the first airships were developed, and travel between mountains became possible, the difficulty of travel kept interactions between the nations to a minimum. However, this all changed with the invention of the steam engine, which facilitated air travel and allowed the nations to expand and interact with each other. A great war broke out, almost resulting in complete domination by the nation that first militarized the steam engine and put it to use on airships. The game takes place 100 years later, where the world is once again on the brink of war, locked in a power struggle.
