Hmmm so on that point, the French one is a bit vague as well, referring to "new lives" or "young shoots of life", so it is leaving it rather unclear, but it does leave me wondering if the newer souls were indeed less potent than the ancient ones and in particular, less/not capable of creation magicks - therefore, less capable of replicating their "doom". It would tie it all together then.
I suspect they will strive towards equilibrium so long as the world isn't already flooded, but then again Elidibus busied himself about on the Source to ensure the balance did not tip too much in one or the other direction, so it's not really clear how correct she is on that point; it does probably occur naturally, as with the 6th Umbral Calamity, but once you've gone into Flood territory, the aether becomes too corrupted to re-balance. For their purposes, the world needs to be close to but not at flooding levels, so I imagine it needs more precise fiddling to be achieved. Anyway, I imagine we will hear more about the Blessing in due course, but to me it does seem fairly clear that attunement to the Crystals of Light achieves alignment to it, and therefore allows for those champions to spread it.
Hydealyn had way less people to summon or fuel her. (Maybe even only those original summoners) What if that makes it so that they could resist it? And because she was much weaker she needed the power of sundering to even be able to try at all?
I think what we need to consider here is that it's not so much the summoners being tempered which is relevant here - although I don't doubt they would be (and again, the intention behind both of these primals was not to summon them as gods, but as instruments to achieve specific goals, so similar to Bahamut's summoning that very likely results in a different kind of tempering.) The question is how the sundered life forms stack up to her. Her summoners are gone; either sundered, or part of her. It is the sundered life forms she enlists which we're talking about. Though she may not be a primal on the order of power of Zodiark, she is nonetheless more powerful than almost any other Primal we know of. There is also the fact that they co-existed (whether peacefully, or not) for a time, and I am guessing they may well have shared an auracite before the Sundering. With the caveat that these are paintings by the sundered life forms, driven by memory of the ancient world, the cave paintings from Rak'tika do suggest she emerged all the stronger from the conflict. Once he was weakened and removed, that power would, presumably, remain for her to draw on. It's not too important, though, because even at a base level, she is more than potent enough to temper a sundered life form.
He definitely isn't - Fandaniel confirms as much.I also wonder if Zodiark or Hydealyn even count as active right now? Other primals always need huge amount of aether that they take from the land to be able to exist. Hydealyn alone should have kinda destroyed the star by now if she really needed aether all the time, the same with Zodiark when he was active. (They only talked about new sacrifices to get old ones back not to keep Zodiark "alive") What if those two simply can exist without hurting the land because the aether that the Ancients used was so massive that they are using this? What if her silence is her simply being so weak because she truly just used up most of the fuel that was given to her at the time of creation and she does not want to take from the world?
She is a more open question. We'll find out, I suppose.Homme à la robe blanche : Notre éventuelle proie est encore endormie, mais une férocité sans pareille bout en elle depuis des millénaires…

On your other point, which is something I've also pondered, the best answer I've come across is that it's in auracites (apparently, the Heart of Sabik is referred to as a black auracite.) I need to re-order that album properly at some point, but 5 follows 9. Their lore is such that they could probably limit how much of the Primal's own aspected aether flowed out while also limiting the need to draw on the Lifestream. Even if they had need to draw on its immaterial aether from time to time, it seems that much like the RDM focus, the auracites can amplify its effects. Even if they weaken over time, we know from the Crystal Tower that they're also re-chargeable. Unukalhai mentions they had a "flaw" in that they would bleed Primal energies, but I think that is intentional - Zodiark's darkness would speed up recovery of the planet. It does make them exceptionally poor prisons for a Primal, but if they work as I suspect, they're a very clever device, that can regulate the outflow of Primal energy into the Aetherial Sea while also limiting their need to draw on it for power. They can also be used to emit a message, like we found out Hydaelyn does in 5.2. Ultimately, very good Primal batteries.
On another note, there is Fandaniel. Assuming tempering survives the sundering for the sundered Overlords (there's some indications it does, albeit memory seems to be the most important driver for them as per 5.4 Eden and the memory crystals in 5.3), with:
-a dormant Primal for which there is now a story route for him not to enslave his tempered summoners
-a flawed/weak memory crystal that is not sufficient to awaken the memories of ancient Fandaniel (assuming he is even the original shard of the office-holder), and therefore commit him to the cause of the Ascians
-quite possibly a plan to just use Zodiark's energy to fuel a new Primal, summoned by already-tempered minions
...he can just go on a wild rampage. Zodiark's return could throw a spanner in that if he were to use any tempering to halt Fandaniel, which is an interesting point.
Indeed, and I think that can't be stressed enough. There are general principles that apply to all Primals, but we don't know the full catalog of them, nor do we fully understand them (aka the writers are leaving open sufficient room so as not to be constrained by existing lore on how they implement Zodiark and Hydaelyn and their final arc - recent stuff helped us understand a fair deal more about why their tempering does not appear to enslave in the usual way.)
A plausible interpretation of it could be to do with the aetheric balance of the Underworld/Aetherial Sea. Granted, the very use of auracites might serve to ensure that any outflows from the primal aren't excessive, and thus contain the influence, but at least some must've been intentional, since the dark alignment is linked to a more active polarity of aether and therefore expedited growth. Zodiark wasn't really there to act as a replacement for the Convocation as the star's governing body and even Elidibus's intention was to aid them via mediation, rather than tell them what to do. All the same, I can't help but think that Venat's main concern really was just to prevent him from reviving the ancients, in order for their preferred outcome (ceding the world to the "new life") to take place.
