[Spoilers] The Device in DT msq

[SkankyRoe]

The business with Alexander only seemed to involve Travanchet giving Mide a horn, and that was able to "draw vast quantities of aether from the bearer's surroundings" apparently on its own, so where (and what) is the tablet, and what is the tablet's purpose?

Was the Enigma Codex functionally a tablet?

Are the tablets related to the explanation of how electrope works, with arcane engravings to direct aether to do a particular thing?

Well there is this:



I feel like it may not be coincidence that the Enigma Codex looks like it's made of electrope, or rather, that electrope looks like material that makes up the Enigma Codex.

[Iscah]

Well there is this:

Well yes there is that, which is why I mentioned it in my list of questions...

But anyway. It definitely has the look of electrope, and also the lorebook illustration of the tablet found on Seal Rock (paired with the horn eventually given to Mide) is a black fragment with arcane writing on it that looks rather like a fragment of the Codex.

I felt this when the comment was made about the regulators allowed souls to merged and only remember the memories of the person who was being resurrected, and someone points out that it is similar to what happens in the 13th except the original "person isn't erased". And in my minds eye I see the quest to Solution 9 to get a regulator, to give it to a scion to reprogram it, and then give it to Zero to save some new character. Like a relative new problem to the main plot has already got a solution waiting in the wings for when we're ready to redeem the 13th.

…I wonder if we could convert a Memoria into a form that a regulator could interpret as a soul?

…I wonder if we could convert a Memoria into a form that a regulator could interpret as a soul?

Yes, but now they wouldn't turn into monsters.

With everything we know so far, I'm fairly confident that Azem is the maker of the key, or at the very least heavily involved in its creation.

While its implied that the key was made post-sundering (thus making it seemingly dubious that Azem could've created it), its worth remembering that they have some form of precognitive abilities, as they were able to foretell the WoL's return to Elpis and their meeting with Elidibus. Seeing how the pre-existing magic of Azem's crystal seem to work regardless if it's being used on another shard or the literal edge of the universe, I don't think Azem would need to understand the exact mechanics of the sundering for the device to work.

Assuming this is the case, then the more interesting question would be why? Why did Azem construct the key, and to what end? Moreover, did they create the device, knowing it would eventually come into the WoL's possession?

In the beginning;
After, Sundering there was 3 Tribes, Lalafell, Rogedyn and Elvan who lived on Eorzea later inhabited by Hyur & Miqote.

Before, the Sundering,
Ancients talk about Volcano and it's settlers and decided to not Intervene with eruption possibility of their losing civilization, implying that outside Elpis there was Tribes of people on Island that is confirmed. We don't know who these people on Island were, but they could be the "Forgotten People" mentioned in Aloha Island dungeon same South Sea ilse settled by Millala and later resettled by lalafell.

These Forgotten People Boss seen with the World Tree, and Emerges from the Wood to fight you with the Sphere Relic, with many symbolism worn on their body as shown in the Facility in Living Memory, who was much larger in Size, almost Amouratine like.
These same race were keen on Arcane Arts, who later helped infuse Stone to create Electrop and Construction Prototype Gate of Golden City In Living Memory, these Orbs are seen in Facility in Living Memory and possibly same orb seen in Aloha Island.

The Seat of the Speaker is in Aylse Volcano in Living Memory, where the Facility that was not made by Millala according to NPCs. Living Memory dates back Calamity of Lightning where Alexandria hailed from.

Millala Ancestors used the Relic to Escape the Calamity of Ice, dates back Thousands of years future AFTER Calamity of Lightning, Fire, Earth.

Azem constructed the Key of interdimensional fusion before the sundering, Speculation Azem might of helped of the Island Settlers whom may have been descendants of Llalafell,
prior to Sundering and Given them they key, Could the Settlers transported their home and Alyse Volcano to the Future Source, like Crystal Tower arrived to 1st but in reverse?
just like when Alexandria Merged with Source in future? despite thousands years past since Calamity of Lightning.

Are the South Sea isle itself from the pre-sundered world? When they used the key again on Source to escape Calamity of Ice, did they also again transported Alyse Volcano to Alexandria, to Living Memory?

Another question if Gate of Golden City exists in Source, and Reflection in Living Memory, would it be possible this same Golden City Gate is in First? or every Reflection? Just covered hidden under the Light Ice of the Empty, this gate connects every Reflection?

What if the Cup is the new Tupsimati of DawnTrail, as it was for us in ARR. as Tupsimati had Etched of Thaliak Scholar, the cup bears Enchanted Mark of Azem, through Prayer, and harnesses the Power of Dyanmis of heighten Emotion and in your Hearts Fervent Desires, possibly through Dreams of Creation, and Memories of Azem housed within the Soul Crystal, etched markings calling upon Celestial Aether to gather mass amounts of Aether for spell casting strong enough to Open Gate of 7th Heaven (Phantom Realm?) to escapes the Sundering as Sundering only affects world, not Universe, this is the loophole in Sundering regardless of what world you are in, the Star in Skys remain the same across all Reflections for ever shinning their light towards us across all Time. Yshtola only needs to keep her head held high towards the Stars and with Relic for her Dreams of Traveling across the Rift to become Reality, with a friend whos Archon, User of Astrolgian arts, and G'raha many others expertise, she's in good company.

Possibly through Goddess of Fate Nymeia. Both are water element. Were they able to channel energy of Stars of Omega & Alexander Celestia Aether to Interdimensional Time Travel through these Gates in Soul & Memories with Power of Echo.
