Hm, I kinda of feel like I"m the only one that feels a little dissapointed that it was actually a spell to send them into the future. Though I think I just have issues with stories that use said "deus ex machinas" to handle a situation. Since then it enters my mind, well if he had the power to send thousands of adventuers into the future and stop them from getting hurt, then why couldn't he send the white raven into the future, one entity, or bahamut himself into the future and give them more time to prep for the attack or even Dalamud itself into the future to give them more time to crash into eorzea.

Rather than do that though he uses the last of his magic to send thousands of adventurers which I imagine is a lot more stresfful then the other ways he could have used it lol.

It is what it is though, perhaps there will be an explanation as to why he couldn't use this spell for the other entities and only the adventurers, I would have really rather have it where the adventurer's themselves become part of the seal that trapped Bahamut and then awaken years later once the seal itself was strong enough to contain Bahamut as well as revealing what will be known as the labyrinth of bahamut.

Though I also guess this is where the mystery as to what exactly did stop Bahamut then, he pretty much sent the only hope away into protection so now there is only the GC, Cid, the rebels and a bunch of NPCs to handle the situation. So it does make you wonder what exactly occurred in those 5yrs that actually stopped the chaos from continuing since something had to save the world from Bahamut.
