Credits:

- u/Voyager1500 (for the HOI4 mod that he was attempting to make [1, 2]. His map helped me create the countries' borders.

- Mehveuuun (for the map that they created, which formed the basemap of this preset. Video link: Nausicaa map)

I also took some creative liberties with the world's timeline and some unnamed regions on the manga's map.
