We are developing a setting for a series of novels and a tabletop role playing game. This story universe is called SublightRPG. The stories take place in an alternate timeline where humanity evacuated the Earth in 1920 following a magical Cataclysm. The story uses realistic rocket physics, rotational gravity on space stations. Most of the spacecraft are fusion powered, and use either water or crushed up rock (regolith) as propellant. Humans in this timeline developed nuclear power in the 1800s, but never developed the internal combustion engine. Thus vehicles like tanks, cars, and airplanes are unknown to them. The height of their civilization was the Victorian era, and decor and tastes reflect that. The magical cataclysm in 1920 was caused by the Great War of 1904. By 1920 the war had been stuck in a stalemate for a decade, and the world powers were trying anything to overcome the deadlock. Some powers utilized necromancy to raise the dead in order to maintain their lines in the trenches. Some powers unleashed radiation hungry kaiju behind enemy lines to lay waste to their cities. Some powers unleashed auxons: robots that replicate themselves using local materials. Auxons would scavenge for parts wherever they were released, dismantling infrastructure from power grids, to bridges, to water systems. Condense this information into a summary that could be used by an AI.
