Idea for a plot point

[ObsidianFire]

Heh... Koji got asked again why Gaius stopped invading after the Battle of Silvertear Skies at the last fan-fest. This is what he had to say about it...

GE: Speaking of stuff we talked about before that may have fallen through the cracks… Do you have any updates on the so-called mysterious primal? There was the idea that right after Gaius took Ala Mhigo, he was going to keep going, but a primal halted his advance. It could have happened in ’57; could have happened in ’62.

Koji: That was related to the whole, “What lies deep beneath Silvertear!?” Yes, something stopped his advance. And then there was the trailer beam, tons of primals shooting out. And then there was the seal. What is it sealing? What was going on in there? A lot of this is where the 1.0 story was supposed to go, and there’s a lore reason for that.

When the Calamity happened, it caused a lot of changes to Hydaelyn. Whether that was enough to seal off something that was already sealed, but the seal was getting weak, or… That I don’t know. There could be something like that. The hint was that Gaius was stopped for a reason, and that it was a powerful force. There’s a presence. It wasn’t just Midgardsormr there, it was more of a force, and I can’t say anything more, for now.

So... Gaius didn't just stop invading Eorzea for fifteen years because he didn't want Primals not to be summoned. Something was preventing him from doing so. What that might be? *shrug*
