-Etherion is just like a Nuke. The place it's shot at is wiped out, so it is definately NOT an option, seeing as how the Dragons attack the very capital of Fiore. -We don't know how long Etherion needs to fire. The one hour period before the attack could just have been a decision of the council. -Jellal can't possibly stop Etherion, no matter how much Nakama power he's charged with (at least not without another giant Lacrima... which would stand out quite a bit. -Etherion can be stopped, as long as it hasn't been fired already.

So much for the purely technical issues.... I won't even comment on what I think about the rest.
