>The void has been shown to be repelled/afraid of the realm of death

an answer to the person who was saddened to see Shadowlands increasingly confirmed and used in the lore now. And this is just the beginning, since, as our good old Sargeras and Jailer thought, only death magic can truly affect the Void; the former injected death magic into the Order (Argus) and the latter wanted to inject Order magic (Azeroth) into death, both with the goal of defeating the Void and saving reality.

Add to this the fact that Miss Shadowlands (Sylvanas) will no doubt be back for Midnight, and that Anduin (Mister Shadowlands) is almost cured of his depression, and we'll be hearing a lot more Shadowlands.

Whether you like it or not, Shadowlands has been one of the most important lore and world-building expansions since perhaps MoP.
