An ominous premonition? (Slight spoiler for the Studium quests)

[KageTokage]

That observation rekindled a hope that maybe we'll eventually get to plumb the depths of the House of the Crooked Coin as a dungeon in interest of trying to figure out what this new potential problem could be, since that's what I assumed the place would be originally.

There's also the matter of that giant aetheric confluence at Carteneau that while brought up in 5.5, never really had its purpose ascertained.

It also brings up the possibility of bringing back into play on what's underneath Silvertear Lake. While one could say it doesn't matter, this dev team doesn't seem to be holding back anything when it comes to tying up loose ends, and what Midgardsormr is guarding is one gigantic loose end out in the open. The way he "stabbed" that airship into the lake was almost as if he was "driving a wedge" into something.

I assumed that must be to do with Bahamut? Similar to the confluences we explore during the Binding Coil raids.

It's a bit odd that Fandaniel never tried to attack or destroy (or harness for that matter) any of the others, so it does feel like a bit of a forgotten plot point.
