This leaves me to wonder about Louisoix. I mean, he talks your ears off. He knows an awful lot about primals and lore, even for a sholar. During the battle with Bahamut he wields incredible power, just look at the size and strength of his shield. He is even able to rebuild the shield while he is getting hit.

Then there is sheer power and MP required for the spell to rip all the adventurers from time itself.

Another thing that puzzles me: When the twelve start to respond to the prayers and their "keys" begin to appear, it looks like Louisoix casts a big glowing "key" into the sky himself.

Who exactly is Louisoix? Can it be that he is a manifestation of Thaliak?
