Pandaemonium's Current Whereabouts (Anabaseious Spoilers)

[shadowclasper]

Nope, was outright confirmed that Athena ripped out a chunk of Azys Lla (specifically the Aetherochemical Research Facility, a.k.a. where Lahabrea died), transformed it into Pandaemonium, and slammed it down into the Aetherial Sea.

You could make an argument that she picked the Aitiascope because that was near where Pandaemonium was, though--narratively it's there because it's the part of the Aetherial Sea we have easy access to, but Athena doesn't have any stated reason she slapped it down in that part of the Aetherial Sea, so that reason's as good as any.

She plopped it down there cause it was near to us and she wanted ti study us remember? Also near all those souls she needed

Isn't the original Pandaemonium kind of in its own pocket dimension? That teleporter we take to get to it from Elpis seemed to take us into another reality where the very air was different from that of Elpis, after all. The sky there was dark stifling. My money would be on it being subterranean or in the Interdimensional Rift somewhere.

It's definitely a loose thread the writers are leaving themselves when they need a cheap and easy filler.

I thought that it was under the islands hidden in the clouds and behind seals, thus hidden deep in the... mawlstrom... below ishgard... fuuuuuuuu
