I want to ask something (SPOILERS FOR EW MSQ)

My question is that though. How do they halt or prevent final days if it is caused by Metetion? It is not logical to think she just sits at ultima thule and waits for Zodiark to die. She could have killed them herself since she really wants every existence to die (or rather not born). But we don't get an explanation why summoning these primals prevents final days. Like what is their deal to prevent dynamis?

I'd suggest getting up to the final boss to understand more of Metetion's reason for inaction, but I'll point to a vague trope of the overconfident villain.
