So, bearing in mind what I said above in my "spoilers so hiding this" post... well, I can see how your (OP's) premise could be entertaining, but it definitely wrecks a whole lot of story, and negates that entire "maturation process," so no---I don't think I'd enjoy it. Glad you enjoy speculating on it, but nope: to me it's fanfic I'd rather not see turned into canon. (I wasn't very happy with the "Tales" story that created the "branching timeline" for the G'raha past, either.)

Now, on what Arkhyna said, sure: it would be fun to find out a bit more what Azem did after the Sundering, and also, I do want us to get to check out Meracydia... but present day version of it, for sure. There's also plenty of worlds out there to explore if we ever get this Cosmic Exploration thing off the ground, lol.
