I had some thoughts so forgive me if theyre all kind of unorganized.
So the entire 1.0-6.0 we defined the laws of Eorzea by Aether. How Aether works into the machinisms of everyday living. While there is discussion that Dynamis sounds like a cheap dues ex machina; I feel like this will be the new set up for possibly 6.0 and onwards.
Everything is Aether, but what if, Aether completely disappeared?
What about Dynamis?
There are some things we know of Dynamis:
Our current world is able to be affected by Dynamis because sundered peoples are reduced to a fraction of their unsundered counterpart. This explained why the people of Eorzea became Blasphemies in Our Final Days as compared to the Ancient's.
One of the major themes of our later quests is that Everything Is Finite. I believe this ALSO includes Aether. Zodiark and Hydaelyn are dead gods of an old world, and it's suggested even Zenos "gorged upon the mother crystal"; what does this mean for Eorzea?
There's a possibility as this Saga coming to a close; our companions will come to face issues with Aether shortages and they might have to come and resolve issues concerning Dynamis--which is also the alleged reason as to why people are becoming Blasphemies( They turn during stagnant currents of Aether; and Meteoin draws off despair to put the pin in).
The ascians goals are null; Zodiark is dead; Hydaelyn has sacrificed herself; The Mothercystal has been "devoured". They were all beings of Aether and consumed it--- and perhaps too much of it.
(Also I don't recall our stagnation of aether being resolved so let me know if it has, I stormed through MSQ when twitter spammed with spoilers.)
It will be exciting to see how Dynamis will play into this as a "anti-matter" to Aether; it's almost synomous with dark aether; but dark aether STILL is aether, no? I also adore that it shares the name with FFXI dynamis; a shadowrealm where beastmen and nations got sucked into--corrupted by nightmares.
All job classes use aether to work; but if SE were to rework any designs; I'd be curious to see if Dynamis will become a main factor in energy consumption. It also makes me wonder if there will be correlation between the ?13th shard and Dynamis.
