Equilibrium must needs be restored [heavy sppoiler]

[Anonymoose]

Another thing that bothers me about their obsession with "balance" is they teach people how to summon primals, which sucks up the aether from the world and puts everything in danger. How is that bringing balance back?

Only Lahabrea and Elidibus, the two who were "of this world," have spoken anything of balance thus far. Nabriales specifically stated that Darkness should consume the Light and return all that is to nothingness, a la the Cloud of Darkness. This, however, is (at least on the surface) in direct contrast to what they have in common with the transmigratory Ascians, that they seek to sow chaos so that Zodiark will be reborn.

There's gotta be truth hidden in properly understanding what that even means (including the possibility that it's a smokescreen), otherwise Lahabrea's plan is to stop the unraveling of the laws governing the aetherial and corporeal realms (literally replacing all order with pure chaos) by ... sowing chaos. And now we have Elidibus trying to clean up the mess of Lahabrea's failed papal-primal project by slaying primals to stop the awakening of eikons because there'd be too much destruction. Did they only want a specific type of chaos? A specific amount?

If Zodiark returns and Hydaelyn is burned out, what balance is gained that isn't also immediately lost?

Urianger said that balance is always sort of present, even if it hangs in the balance of a swinging pendulum...

is where is that aether going?

From the primals? Do we have any reason to believe that it's going anywhere aside from being torn from the land and then returned to it?
