I've been thinking about the recurring theme of "death comes for the soul of Azeroth" that has been present in this expansion.
From the pre-release media describing the theme/story, to the Jailer proclaiming it during the escape from the Maw scenario (Death comes for the soul of your world!), to the Primus repeating that same line (Death comes for the soul of your world, mortal. But together, we may yet save it.)... and now for official descriptions of the next patch by Blizzard themselves uses the same line: the soul of Azeroth depends on it!
So thinking about this while also thinking about what we know about the world-soul of Azeroth since Legion and BfA, I can't help but think the Chamber of Heart and Sargeras' sword coming into play.
The Jailer so fixated on getting to the Sepulcher of the First Ones in order to "rewrite the rules of reality" yet he still wants the "soul of Azeroth" at the same time.
What could Azeroth's world-soul have to do with the desire to change the laws of reality? Do you think one will have to do with the other? Do you think the Jailer needs to first "rewrite these laws of reality" in order to gain access to Azeroth's world-soul? Do you even care at this point?
EDIT: Yes, this question came about after seeing this post on the WoW Reddit: https://www.reddit.com/r/wow/comment...tory_is_going/
