World Collapse, could be something big happening. It could be just because Acnologia is in that ravine of time... he's somehow resistant to it and trying to get out...

But haven't gone out yet, everyone assuming or thinking it might be the world collapsing. No one has entered Ravine of Time i assume, so they don't know what the effect of it might be until now. Maybe they never expect to have a crack in time and space if someone that big is in there.
