Can't answer that. Never really had a world.

[Spira hadn't been his home. Zanarkand had just been dreams. Hell, how's he even standing here right now?]

...World I came from was called Spira. Hell of a place. Back in my day it wasn't like it was recently... fewer fiends, not anywhere near as rough a trip if you were heading across it all. But always one big, ugly thing called Sin lurking around, smashing up the place and killing people wherever it could. Got to be a guardian for a Summoner for a bit, so yeah. That's what I'm used to.
