Here's how I see it: my character was in Limsa when the Calamity happened (which is true, that's the last place I logged out.) But, she then traveled through Ul'dah to fight the empire when they attacked the city. She has no memory of this (as it was unsaved content after Nov. 1.) However, her spirit, along with many others was already absorbed by whatever magic it was that we see in the end of an era movie, which is why she has no memory for a short time. In my own story she traveled home for five years to recover. She remembers things from the world before. It's everyone else who doesn't remember her, and even if she tells them they won't remember. That's part of the magic that made everyone forget.
