I don't believe it's discussed enough how Venat/Hydaelyn has no downsides.

We have the unsundered Ascians on one hand who are depicted as struggling emotionally and psychologically with everything from the end of their world to their laborious efforts to restore it over the course of several millennia. This eventually leads them to making missteps by the time the WoL encounters them resulting in their deaths and failure of duty.

Meanwhile, supposedly Venat had suffered for the same amount of time, but displays no ill effects from it. On the contrary, she is the picture of mental clarity and purpose. At most she says she had bouts of despair, but was able to overcome them thinking about the WoL.

She's also singularly the only primal to have no consequences of being one. She doesn't require aether beyond her original sacrifices and she doesn't temper. Conversely, even though the first part is also true for Zodiark, there are still numerous people who insist by nature of being a primal he was some sort of blood god who demanded endless sacrifices. This mentality is never applied to Hydaelyn who, as a primal, should be no different using that logic.

I suppose I should just chalk this up to the rules don't apply to the "protagonists" because that seems to be how the writing for this game has operated since HW.
