What if the Titans realized long ago that Azeroth was so strong they had no way to actually manipulate her into becoming a titan and so they built the facilities to instead teleport her out and into a different timeline where she can’t interfere with their plans? It would explain why they helped create the emerald dream as a sort of back up to Azeroth.
If this is a legit question… it might be better in the “Story Forums” which deals with those sorts of questions of questions and speculations.
That out of the way… as far as I’m aware the Emerald Dream wasn’t so much created as coopted by the Titans.
So far all of the logs support their intentions to manipulate Azeroth into becoming something they wanted her to be while she resisted and fought back even demonstrating the ability to “infect” the Earthen, probably others as well, with the desire, and the power, to resist the Titans and protect her.
I was thinking about Aman’thul, the guy who literally can create and see through timelines. I am not sure that our timeline is the prime timeline so much as it has been entirely cultivated by him. I was thinking about the Titans we have. He could have seen all the technologies, found one that allowed him to manipulate world souls, planted it into world souls of the different cosmological origins (Eonar being an Arcane being is weird… same goes for others), forced those souls into being what he wanted and created his pantheon.
Now he is trying to prune away all the stuff he doesn’t like. The problem is that the players don’t flow in the same time. As Elisande said " Time eddies about you fits and starts. Nothing is certain!" We don’t fit his timeline, we are the factor he can’t control but we seem to have great influence on the main story. If Azeroth is convinced by the players to keep fighting him, will he let her be?
What happens if the other Titans realize that Aman’thul has been manipulating them from being what they should be? Would they abandon him and leave him to be the Last Titan? Maybe he killed the original titans and he wasn’t alone to start? Maybe they wanted the universe to be free to do what it does and he wanted order because the chaos of the timeways was too much?
