The Story of the First Generation I

  (spoilers for people who read Age of Heroes)

It is the name of the Empire that Azief himself took

When he returns back to his world and build a small kingdom (though it could be likened even more to a state instead of a kingdom) he took the name Eden as the name of the force that he had created in the Fake World

The stint was quite short since he had decided to return back to Earth Prime and destroy the Fake World and release the beast that is chained with the Fake World

However, even though he was not in this time when he appears in Earth X in the past, he knows what this period of time is called

This is what the later generation of this world would called the era of the Sky People. 

And Aero, Zeus, Amanda, Kyle, Dan and many others that is from Earth two would leave an indelible mark in this world

'And of course, there are the Gods' Azief said to himself.
