(Spoiler) About amaurots downfall

[Riastrad]

It sounds oddly enough like the villain of another Square title. Lavos from the Chrono series. With time being a central plot point of the story, I can see the story team using old references to past titles as needed. Time compression is for sure going to have some effect on the story coming up. Heck, we even see past expansion CGI in the opening to this expansion. Why show any of that if certain events are not going to be brought up and possibly changed, time is not as rigid as it seems.

I use the song lyrics for Shadowbringers for a fair amount of my theories (and because it is so freaking cool). But, I think they have a lot of relevance to the story.

Authors of our fates
Orchestrate our fall from grace
Poorest players on the stage
Our defiance drives us straight to the edge
A reflection in the glass
Recollections of our past
Swift as darkness, cold as ash
Far beyond this dream of paradise lost

To me that last bit means that after we dealt with the shades of Amaurot, old failures are going to be brought up again. If we can change our fate, why can't we change others?

Want for nothing, nothing denied
Wand'ring ended, futures aligned

*pulls a certain knight to safety and stops a betrayal before it even happens* One can dream.

Unspoiled Mor Dhona actually features in the opening CGI for 1.0, where the Warrior of Light fights along companions in an Echo vision against a morbol moments before the Empire invades and does battle with the wyrm.

Unsupported theory here for a second, but what if that CGI took place in the First? We are led to believe that the Source of the First and Silvertear Lake of the Source (confusing I know) are linked. During the trailer for 1.0 when the derplander (really Ardbert, we just didn't know at the time) gathers guildleves for his group and sees that vision, it didn't really happen to them, but to the WoL on the Source. So Ardbert accidentally sees what was going on in the Source during the Battle of Silvertear.

I understand the story was not planned that far ahead, but they did reuse the Crystarium, Cylva, and many other project "Rapture" ideas. It can not be understated as having some affect on the current story as Yoshida has always been active in using the original dev teams work as a basis for the story he wants to tell. Dalamud being a prime example.
