Shadowbringer trailer question

[Daralii]

We don't know. Yoshida and everyone else have kept very tight-lipped about when and where ShB is taking place, and we probably won't find out until Tokyo.

The trailer has thancred mentioning about changing the past.Miniflia is a younger age.The place you see thancred looks like possibly the first boss room in ampador keep.Mentions that the place has changed.
It looks like we're going back in time to undo the calamity by traveling back even further before the events that made it happen.

If that's the case, we should see some old zones "revamped" since the Calamity greatly changed the aspect of Mor Dhona and Coerthas.

The West Shroud was also completely destroyed by a chunk of Dalamud.

The West Shroud was also completely destroyed by a chunk of Dalamud.

The West Shroud is not actually destroyed, it's just never been made accessible in ARR (an early Gridanian ARR quest mentions about a Wood Wailer unit that had recently returned from patrol in the West Shroud, meaning it's at least intact). Presumedly it's closed off to outsiders to allow the forest to recover more, or something. The chunk of Dalamud you're referring to is actually in the North Shroud (it's where the Second Coil of Bahamut is located). Either way, that quest at least proves it's still intact.

You can see it in the distance in North Shroud. The entire area has been turned into a mountainous mass of corrupted crystal, and while it's partially accessible as per that quest and the Feast map, it's probably safe to assume that most of it beyond the border isn't.
