The Seventh Astral has a big thing of 'standing on the shoulders of giants', a lot of the leading minds and civilizations are building on departed people; mostly Allag, but others contribute too. But if those giants just didn't die, they'd be perfectly well-suited. Immediately I can look at Allag and say they definitely had everything needed to pull off Plan 'Punch Meteion In The Snout', and I wouldn't scoff at someone saying that Mhach had a chance either.
What I'm saying is that Hydaelyn definitely tried to stop those Calamities, failed, and was reassured by 'well, at least the Seventh Astral Era has good odds'. That's not saying that others wouldn't have had a chance if she'd protected them--and also not saying that later Eras would've been totally lost--but is saying that we are her reassurance. If we die, she doesn't even have a prayer.
