The Central Powers achieved victory over the Entente in the First World War, with that set, let me go 100 years into the future, more exactly the year 2033, the world entered a second space race, toggling the desire of humans to once again explore the skies, as the great Kaiserreich is going to endure a risky mission on sending astronauts into an unknown planet, setting off a new danger not only for this planet but for the whole multiverse.
The world of this story is influenced by the world of the Hearts of Iron IV mod Kaiserreich: the Legacy of the Weltkrieg.
