The Void shows up and it’s big and scary and universe-ending. You know, the same as all the other expansions.
Yrel shows up with the Army of the Light to help but it turns out she’s “corrupted” by the Light or whatever. We have to ask Sargeras for help, continuing the Warcraft trend of bad guys becoming good guys (kind of) that help save the world.
Things start going sideways and we learn that the Void is a parasitic entity that sucks the life out of every planet it comes across or something contrived like that, so we have to go back to the Shadowlands and get Anduin and Sylvanas.
Sylvanas and Anduin establish a platonic Brooding Older Sister/Annoying Little Brother relationship, which pisses off all the weirdos who ship the two together on Twitter. They work together and find some ancient eldritch entity that reveals that Sylvanas is the Chosen One.
Kerrigan – I mean, Sylvanas then accepts her destiny with the help of Anduin and we help her banish the Void and she sacrifices herself except not really because no one ever dies in this clown fiesta of a fictional universe.
nzoth comes back and a void expac happens and it expands on the void elf story where it left off and introduces void elfs open up to a new class paladin ! then it leads us some how back to the giant sword and we try to heal azeroths wounds , i don’t know maybe illidan will come back somehow too and well catch up with him . who knows maybe sylvanas will comes back and say she is done doing the maw dallies .
and then somehow itll introduce san’layn , vrykul ARs somehow they’ll be apart of the story im not sure how but can only guess . Etcetc
Evil Future Yrel shows up and demands everybody join the Light, Turalyon agrees and invades the Horde, and we have to work with Anduin and Alleria to stop them from killing everybody. And then at the end of the expansion it’s revealed that it was all a setup organized by… I dunno… gnomes or something.
It’s probably the gnomes.
In fact, we’ll find a way to kill Arthas again, just for funsies.
