MSQ Spoilers/Thoughts/Inquiry

I really enjoyed this patch overall, happy to be moving forward with the next story arc too. The dungeon and trial were enjoyable, I liked seeing more of the 9th I assumed was still down there, and we even got another roleplay segment (as Krile no less!) Without going into wild speculations about our unintentional use of the key moving forward, I have the sneaking suspicion Azem had set this plan in motion long ago and we're the latest in the link to be fulfilling whatever it is, but I could easily see them taking this in many directions.

One thing has been bothering me though, and I'm hoping someone can help explain because maybe I'm just confused, but does Miyali still being alive not present a huge contradiction in the timeline? When she was presented as Krile's aunt I was instantly confused because I wasn't expecting her to find any living relatives there that weren't descendants.

Afaik Krile's parents (Robor and Alayla) were around during the Storm Surge, which we know from several accounts was 400 years ago, so how exactly would Miyali have known her sister, and still be around now? I was under the impression time flowed much quicker in the 9th, but maybe I'm missing something so any clarity would help a lot here, thank you!
