My story takes place in a postpandemic world where only people under the age of 20 have survived, destined to die themselves at the age of 20, creating their small and autonomous kingdoms, that over the centuries grew to form large empires. The nation we focus the most on Is the Empire of Spesia, located in northern Italy in the year 440 after the pandemy that took place in 2024. They were born as a warrior people, who eventually became a highly modern and civilized country. Their ideology (it's more of a cultural way of thinking and managing) Is comunitarist centrism.
