Copied and pasted from a Reddit post I made, but here's what I think will be the rough order.

- I think the Amaurot/Anamnesis stuff comes first. Y'shtola is still there at the end of 5.2, and we go to meet her after she summons us (rather than her leaving and going back there again, which seems a little pointless). These scenes do seem to have a slower/calmer feel to them which makes me think they take place before all hell breaks loose. I think we could see Y'shtola have her first bout of aether sickness here.

- There's a bit of a "blind spot" here as to how we get from there to Eulmore, but since the end of 5.0 shows us ending up on the shore of Kholusia after we leave that area, that could be a possibility. Not exactly sure how or when Thancred comes back from his scouting either, but at some point we all end up in Eulmore together. Either way, that's where I think we're going next.

- Here we see the starshower/Amaurot rising out of the sea and realise that something is going wrong at the Crystarium (the scene where the Exarch gets stabbed looks to be reasonably early in the patch given that none of his clothes are crystalised at that point - I'm guessing the stabbing accentuates the crystalisation). The plan is to go to the Crystarium to investigate/notify the Exarch, but after another bout of aether sickness, it's decided that the adults will stay behind as it's too dangerous for them (I'd LOVE Ryne to stand up for herself here and assert that she is able to go alone - they've foreshadowed twice to us that she hates it when Thancred gets hurt or is ill, and wouldn't want him to risk his safety. They also need to show her independence in the MSQ for people who haven't played Eden and this would be a good way to do it). The Twins, due to their shorter time on the First, are also able to go as they are not yet experiencing the dizziness.

- We secure a Eulmoran airship and the kids head off in the direction of the Crystarium. Shortly afterward, the WoLs attack both Eulmore and the airship at once. Urianger tells the Warrior of Light to go and find where the airship went down and make sure the kids are OK (it seems we stay with the adults at first? The scene where Thancred gets attacked seems to have us standing next to him on the walkway).

- We find the airship crashed around the border of Il Mheg and Lakeland, and everyone is safe; this is where we potentially run into an escaping Exarch (not in a very good condition) and possibly Lyna. This is where the dungeon takes place, where we're fighting through an enemy-infested Il Mheg and Lakeland to get back to the Crystarium. I think it's clear the adult Scions will not be available for the dungeon and that the Exarch will be the tank for it, at least.
