^yes but zodiarks barricade is failing and it didn’t protect the ancients properly, so if she didn’t sunder the ancients then the final days would have consumed them and then the rest of intelligent life would have failed when zodiark’s barrier failed

Venat sundering bought the source 10,000 years for humans to recover enough to stop Meteion before zodiarks barrier failed

This is not to say that venat was responsible for the barrier of zodiark but the ancients were still at a dead end, they couldn’t stop anything and their only plan was to keep sacrificing more to bring back people they had already sacrificed

Venat was the only way forward even if that way was through an ocean of blood
