So I’ve kind of collected my thoughts after that wild ride of an MSQ. I put most of them in a Reddit thread that implied Zodiark represented Free Will and Hydaelyn was more controlling. I generally believe the opposite is the case. From what we know, I think we can infer a lot about what happened. I’m sure a lot of it may be redundant with what has been discussed here but I thought to post it anyway.
There’s a lot to talk about here, but there’s one thing I completely disagree with - Zodiark is aligned with free will while Hydaelyn imposes her will.
Zodiark tempered his followers, Emet-Selch says it himself that he is tempered. Zodiark is the creation of the Ascians before they were Ascians, so all the Primals we have dealt with are an indiciation of his nature since the Ascians taught it to the beast tribes.
Now the question of why they would create a tempering Deity is an interesting one and I have my own theories (though I’m open to others). I believe it was done to keep people in order, so as to avoid the confusion of rampant thoughts. The Calamity they faced was of their own making, of their own mind. It’s a dangerous thing that their thoughts beget creation, so Zodiark was their solution. He has the power of tempering because as the term “temper” implies, he’s there to keep things balanced and in check.
Hydaelyn is, quite frankly, the opposite. She did not let anyone know she even existed until recently. She required no worship and never asked to be summoned or used. She stays in the background, trying to keep things running.
Her main words are “Hear. Feel. Think.” If you look at “Answers” and at most of her dialogue in game, she has one main philosophy. She wants her creation to think for themselves and experience things in their own way.
I’m not saying Hydaelyn is some perfect god. Just that she represents the remaining Amaurotine’s desire to live freely. Originally, she may simply have been as they said in-game, a check and balance for Zodiark. Basically, Zodiark was given executive power, she Hydaelyn was made as a voice for the people so that their interests would not be forgotten. Inevitably, they clashed. Emet says they fought many times, it wasn’t that Hydaelyn simply roflstomped Zodiark upon entering the arena.
Both entities are just built to fulfill their programming, like a machine. There may come a time when we are at odds with Hydaelyn and we have a lot to learn about her conditions for summoning (i.e. her initial programming). But I think we can infer some things:
1) She is a Primal that doesn’t Temper. (Inc “We’re tempered by Hydaelyn”). She was built specifically to counteract that nature of Zodiark.
2) Hydaelyn’s ability to Sunder is as Tempering is to Zodiark. This is their special ability and their equivalent solution to stopping a repeat of the previous Calamity. Sundering stopped the use of Creation magic which was volatile and potentially Apocalyptic.
However, in any case, all we know about Hydaelyn points to her being a huge proponent for free will and diversity of belief/thought (hence creating differences in people). Zodiark is the opposite, he’s there to create order through control.
