The large sword that hit the ground, I bet will be in the fight with Bahamut. If it is, we will need to pray to it to help defeat Bahamut. Why pray? The video shows them rising back up after Y'shtola, Thancred, Papalymo, and Yda prayed at the shrines.

It will mostly likely cause an anmesia effect on him with a gravity effect.
That's not the same keys, it's the twelve attempting to seal him. Y'shtola, Thanacred, Papalymo and Yda had to pray at the shrines for Louisoix to summon the twelve, the light rising from them was showing him that he could summon the twelve.

There's still a lot they could do, what if the keys contain monsters that drop items needed to weaken him, or we have to break them open to get something, of course there is the pray at them. SE could add them in so many ways.
