[Ongoing Thread] Endwalker Lore Questions [Spoilers]

[Loggos]

My main concern after the MSQ:

What's gonna be going on with hydael- er.. Eitherys's aether, and the environment that relied on it, after we directly tapped into the mothercrystal several times to get to the literal end of the universe? Was killing hydaelyn/zodiark enough to replace some of that aether? Is dynamis/akasa going to be a more prominent feature to the world? (in a less apocalyptic way) Is this how we're going to reset the power levels?

I don't know just how much of the crystal was used, but burning enough to get two "vehicles" to the edge of the universe in such a short time could not have been insignificant.

I can't answer these questions directly but I might have some interesting points regarding

Dynamis.

My friend speculates that Dynamis is essentially the magical equivalent of dark matter/dark energy: Not only is it a magical force that is most prominent "between the stars", the MSQ dialgoue also states that 68% of space consists of Dynamis. It is also very mystical/hardly understood and difficult to pick up for aether-based beings.

These are exact parallels to dark energy.

See NASA:

"Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 68% of the universe is dark energy. "

Aether on the other hand seems to be the magical equivalent to matter, considering that it flows through everything consisting of physical matter (living beings, plants, food, the planet itself).

Of course both have their magical properties that go beyond the physical forces (Dynamis reacting to thoughts and feelings and Aether extending to the soul...which should also include thoughts and feelings I guess?).

But because of these parallels I wonder if Dynamis can ever really replace Aether in its fullest form, just like dark matter can't just replace matter. The question is how analogous to their physical counterparts they are supposed to be or to what extend magic makes them different from their physical inspirations.

Of course we have seen that Dynamis can create "matter-based" beings like the monsters or Meteion but at the same time it also seems to be a force that is elusive and hard to control, so a world that is still originally based on aether/is built to funamentally tun on aether might have a hard time just completely "switching" to Dynamis as a new source.
On the other hand, Hermes has also found a way to control it, so well even that he was able to create life from it. Maybe scholars and scientists like those from Radz-at-Han can ultimately find ways to use Dynamis as an aether replacement and channel it into the world.
