So about the five years between the Calamity

[Ameela]

So since I couldn't log in on PS4 I decided that the best use of my time would be watching the intro movies again since they're pretty cool and well animated.

But the ARR one got me thinking: the adventurers from 1.0 were transported 5 years into the future, which explains how they survived Eorzea being reduced to ashes by Bahamut, but apparently the other NPCs have been around in the "realm reborn" from minute 1 after Bahamut's attack? How did they manage to survive without also being transported into the future, am I missing something?

EDIT: wew just noticed I forgot to finish the title, it's supposed to be "between the Calamity and the start of ARR" but ah well, that's what happens when you go on the forums right after waking up lol
