Space is the thing you see above Eorzea when you're walking around outside with your head tilted back right? I dunno I think I'd get agoraphobic and scream "Wanna go home! Wanna go home! Wanna go home! Too much space! It's too big! Wanna go home!" And besides! Bahamut came from space! I don't wanna get eated by space dragons! @.@
