Spoilers - plus help I don't understand the warriors of darkness storyline

[Cilia]

From the one line we get regarding the Warriors of Darkness' reason for formerly opposing the Ascians, it sounds like they just puppeteer history on the Reflections.

This day we reclaim the reins of history! This day we rid ourselves of the Ascians forever!

They would likely do this to maintain relative balance, lest a Reflection become drowned by Light or Dark and become a Void. We know so little about the Reflections that there isn't much to do but guess at this one, lol. Maybe they trigger Calamities on the Reflections... but I can't fathom why they'd do so, given the Reflection needs to survive to have its Shard Rejoined. (Again tying into why they don't want Voids of either flavor.)

Lahabrea mentions the aetheric imbalance, though what exactly he means remains unknown. He makes it sound like a natural disaster will occur if the aetheric imbalance is not mended by complete Rejoining, and may be correct; the Light seems weak on the Source, but we never do anything but banish the Dark. Elidibus also mentions the balance is tipping toward Light in the ending of Heavensward, so they may be right... though what exactly that means is the question. (I have no answers because there's still no evidence to draw a conclusion from; we now have most of the "how" behind the Ascians' actions, but the ultimate "why balance the Source?" remains.)

I struggle with Lahabrea's seeming inconsistency pretty regularly. It's such an important scene that I doubt they'd let it slide if it was less-than-accurate, which leaves only the possibility that it's less-than-clear, or that Lahabrea is less-than-thorough. The best guess I have (today) is that half of his speech is focused on the Praetorium-Present (we've been spreading Light and preventing a Rejoining) and the other half is focused more on the long-term goal (the Rejoinings must take place in order for Zodiark to be reborn). In the meantime, stopping the Rejoinings is, to the Ascians, the preservation of an aberration - and Hyadelyn's support of it a cancer on the fabric of the universe.

He seems pretty adamant that once Zodiark is reborn, however, Hydaelyn is going down - complete excision. Elidibus doesn't necessarily deny this, but he frames it prettier - lacking in Lahabrea's "Chaos shall reign forevermore!" and focusing on "Hydaelyn will regain Her original form." Unless Zodiark originally did have a dominant say in things...? We haven't really any hints that he used the power he took, though, or that he had it for very long. It might be too soon to be waving that flag around, lol.
