Try not to let the word out, since I don’t want to cause a panic… but there have been reports of more humans nearby. This is an egregious betrayal of the peace that we negotiated with that miserable Jaina Proudmoore! We can’t allow humans here in Durotar, and especially not here in the Valley.

Kilrok, how did we lose Honor’s Stand?
It was a clever ruse, . Alliance forces streamed out of Northwatch and marched up the gold road, besieging Crossroads as dusk fell. Then, in the heart of the night, they force-marched southward, leaving their campfires burning behind.
Our meager forces at Honor’s Stand were caught unawares as the Alliance poured through the pass at dawn’s first light. Many of our bravest warriors fell before their blades.
Gossip This was before the Cataclysm?
Yes. We regrouped east of the pass and prepared a counter-attack, but the next day, the skies reddened and the land was cleaved in two, as easily as a child might split open a cactus apple. See how the devastation stretches from horizon to horizon?
During the Shattering Varian threatens war on the basis of the belief that the Horde was behind a Twilight’s Hammer attack in Ashenvale, and was only convinced not to do so on the condition that Thrall take responsibility for it and apologize. Not only did Thrall not do that, he made Garrosh, who Varian believed orchestrated the attack, the Warchief, at which point the Twilight’s Hammer slaughtered a gathering of Druids trying to establish peace, which Garrosh effectively took the fall for.
At the end of the book, Thrall boards a ship set to bring him to the Maelstrom to work with the Earthen Ring, and that same ship is the one which a Theramore fleet ambushes during the Goblin intro experience, seeking to capture Thrall.
The Horde didn’t attack her allies first. To be fair, she and the Alliance mistakenly believed they did.
My stating what happened there wasn’t meant as an attack on her actions in trying to drown Orgrimmar, it was to establish the way in which her character suddenly flipped from nonsensical peacenik to vengeance and back to nonsensical peacenik practically on a dime.
It was. Both of them purged a city on bare suspicions.
She killed multiple Blood Elves, herself, who weren’t resisting. No, I’m not referring to when she’s touring the city, which people like to claim was merely a bug. And the Sunreavers, as an organization, weren’t guilty. Arguably one Sunreaver helped, and Aethas stood aside and didn’t actively stop it because he was threatened. Which, in fact, is another parallel to Stratholme, because in insisting Aethas was complicit in a crime he didn’t stop, she’s also effectively admitting her own complicity in Arthas’ crimes, which she literally turned a blind eye to.
Regardless, the vast majority of the Sunreavers persecuted in the purge had absolutely nothing to do with the theft of the Divine Bell.
The point is that in WoD she helped, while in Legion, under much worse circumstances, she abandoned Dalaran.
Edit: I forgot, she also let go of her anger again at the end of War Crimes. So her still hating the Horde PC and ordering the Kirin Tor not to help them in WoD is another flip-flop.
There is no proof that was happening on the Broken Shore though.
Speculation.
Blatantly ignoring the reality of the situation.
Nobody ever blames Jaina for anything, that’s exactly my point. This is because she’s a terrible writer’s pet.
