Ning, Ely, and Emma went on a trip around the world.
Their trip included going to every single place, every single city in the entire world, and staying there for a couple of days at least.
That would take them years to complete, but what else could they really do?
The trip started from the nearest place to where they were right now. Japan. Or at least, what was remaining of it.
In the last hundred thousand years, the country Japan no longer existed, and in its stead was a new land that was way too divided to have a name.
That was the case for every single country and location all over the world. Humans had died to almost nothing and went back to repopulating the planet so many times that the knowledge of the old world no longer existed.
No one remembered when the planet didn't have Qi or Mana. No one remembered when the sky wasn't always dark, but rather had stars.
