The cutscene appears to be stylised in nature, but she is describing what occurred after the first stage of sacrifices to forestall the Final Days. There was a second set, that took place after, to revive the star. That is what that scene appears to be referring to, seeing as the skies are still aflame.
Here is the established sequence of events. If I were to take it literally, it'd make an even greater mess of the story than it already is and imply outright retcons, on top of which it is utterly ludicrous to expect me to believe this change in sequence in events would not affect the future timeline at all... so I assume they're playing a game of fast-forward to slip her narrative justification for her mindset in. In either case, the timing appears to be before the second set.
I am not surprised that the ancients, still walking upon a star that had been eaten inside out, rejected the platitudes she's babbling about in that cutscene, while providing zero explanation for them.
