Zodiark's Codex entry what do we think about it?

[SilversLyu]

Endwalker really went too far with the othering of the Ancients and then pushing the idea that they didn't deserve to exist as they were both culturally and biologically wrong, it's therefore a good thing they were replaced with the correct races. It's a really heinous plot and the amount of praise it heaps on the people that did it is pretty vile

What Venat did was in essence eugenics, replacement of the race for a stronger and "better" race. The only other type of person who tops her in this regard is Athena, the very epitome of evil. Regardless if Venat had good faith or not, was fully aware of all the implications of the sundering or not. The devs paint a more or less onesided picture, they may not have noticed it until it was too late but these discussions are testament that the ancients had more potential to survive than is let on.
