With all of the back-patches highlighted like that, I wonder if 4.x is going to give us some more insight into Hydaelyn/shards/primals/aether. It's been woven in since 2.0, and I'd like to see them continue that story, too, since it's very clear that "Garlemald/the Empire" isn't our endgame enemy, the Ascians are (and possibly more that we're unaware of/not expecting.)
