I was always under the impression that they’d never make a branching storyline with separate outcomes in the horde rebellion arc. At most, it’d be this situation where you play along with the traitors to expose them but then Sylvanas is toppled in the end with separate rewards and achievements for being rebel or loyal with loyalists being grudgingly pardoned in the same speech where newly crowned Warchief [censored] praises those who stood beside him in ending the tyrant.
I’ve predicted plots before and this won’t surprise me.
Usually it’s the old god critters who vaugely allude to future events since they’re beyond space, time and death but I suspect Chronicle 6 will include a small aside about how Varimathras was actually the Legion’s spymaster or prophet equivalent, using a scrying pool ritual to see the future back in Wrath and mocked us with the truth in Antorus;
"So, your Alliance still endures. Longer than I expected, though she has already planted the seeds of its downfall. She is patient, that one.
When your thrones run red with betrayal… when your holy places burn and the shattered mask hangs above your hearth… only then you will know. And it will be too late.
It matters not. You are blind to the true darkness closing in around you."
"So, she found me at last. Sent her underlings to finish the job.
Tell me, when she seized your throne of hides and bones, was your allegiance forced? No… I’d wager you surrendered it willingly… or were convinced you did.
It matters not. You are blind to the darkness in your midst."
And the stinger: “Better that you died here, where she cannot claim you.”
The ultimate plot twist is that Varimathras was a good lad all along and that the whole siege of undercity situation in Wrath was about him trying to stop Sylvanas early on, his vision informing him of her long term plan and of what she’d become without Arthas to distract her from the darkness inside herself.
