In the "End of an Era" trailer we see Bahamut break free of Dalamund, which we now know was constructed by the Allagan. Shortly after, the Scions attempt to recapture Bahamut in another spherical prison.
We're led to believe that the power used to materialize this contraption was of The Twelve, summoned by the Scions. Is this accurate?
If so, had they succeeded in completing the cast, would the prison have been the same as the former, a "Dalamund II" if you will?
Assuming that outcome, is it not safe to assume also that there is a connection between The Twelve and the Allagan?
What can you reveal about this event?
