If that's the case it's possible the seal existed even before the Calamity or was even created at the moment when it was used to channel the Power of the Twelve during Bahamut's rampage.
I did check for that before making the topic, because I was also curious. Tupsimati is still in the room when Elidibus shows up. In fact, Nabriales tells us that the seal had no effect on Elidibus or Lahabrea. Elidibus just completely ignored Tupsimati, though, which I have to assume is because he's playing more of a long game, hoping that as we more fully manifest our Echo we'll sway to the Ascian side.

Though, now I have to wonder what would keep Lahabrea from going after Tupsimati. . .

Also, do we know when Ramuh was first summoned? I get the impression it was around the time of the Calamity, but I don't think I've seen anything definite.
