I thought people still lived there and tried to fix up the world, but i haven't played the second game in a long time, so I might be mis-remembering things. I just imagined the character was born there, but has moved around since. Actually, maybe she returned to try and help the committee there. If that's the case though, than where really, is fine.

Don't forget Rule #4:

4. Canon story events from Chain of Memories and onward are to be considered irrelevant.

Sora, Riku, Donald, Goofy, and Mickey never returned from sealing Door to Darkness. As such, future events were affected. Though now that I think of if the Hollow Bastion Restoration Committee can still easily be founded without any input from Sora and crew, so I'll concede that to be an error on my part. Even so, Hollow Bastion restoration wouldn't have lasted long before the Committee was run off by the Empire forming.
