Who knew the 6.15 Omega Quests… (Spoilers)

[Iscah]

I seem to recall one such quote, but I can't seem to find it now. Do you have it around? It doesn't seem to be in Anamnesis.
As for your 1, not necessarily. Beings of similar aether density already exist in the world, namely the multitude of familiars.

I don't recall any indication that standard familiars have thin aether. Wasn't there a sidequest where researchers were concerned we were so aetherially thin and needed more aether?

Meteion proves that it's possible to build familiars differently, but that doesn't mean it's standard.

Well, we could still be that Azem - it just might not have happened yet (;

Regardless of if that wild theory comes to pass, we aren't Azem now, even if future-us could be.

Hyth has a rare aetheric talent for identifying souls that nobody other than Emet has. You would expect that his other qualities as an individual, least of which include his intellect, knowledge of tactics, and diplomacy would make him recognize his own value as a potential Convocation member. His inferiority complex is absolutely a reflection of his society's value system.

He acknowledges that he is the stronger in aetherial sight, but weaker in other fields. We simply haven't seen enough to confirm whether this is self-deprecation or an honest judgement of his abilities – which in any case are being applied well in a different role.

I don't get the impression that he "feels inferior", rather that he knows his limits and is comfortable in acknowledging them.

So... after Venat used almost all of Krile's corporeal aether...

I didn't get a sense that was the case. Teleporting put some strain on Krile, but my impression was that Hydaelyn used her power to relocate Krile.

At very least, using "almost all of her corporeal aether" doesn't sound like a phrase they used within the game, and doesn't sound particularly healthy given that the body itself it made of aether. So if anything, Hydaelyn drained whatever excess aether Krile normally has for spellcasting, but not "all of her aether".

I don't recall her being all that concerned at Raha collapsing after his spellcasting at Zot either. From memory, it's more "empty battery" than "brink of death".
