You can't assume that Mana Clash even exists anymore. It hasn't appeared since DAO. Combat mechanics have changed.
The purpose of feeding the saarebas lyrium was to supercharge their abilities. Based on the saarebas we saw in Trespasser, I would say they were at least partly successful.
That didn't even happen in Orlais with Corypheus and the Breach.
Why, do spells suddenly vanish from existence from game to game?
Yes, which we see with all mages who use lyrium as an item. So what? That doesn't mean Par Vollen authorized it, and it doesn't mean they will allow it after Viddasala tried it.
Sure it did. They just didn't bother negotiating for real until after Corypheus made an actual move. Before that it was all positioning and secrecy. They weren't even aware of the threat. When the threat was revealed, the real talks began, and the Inquisitor can broker a peace deal between all three people for the purpose of stopping Corypheus.
This is part of our previous discussion about my belief that it was a type of CC. Therefore, Viddasala would recognize how she came into possession of the documents with accompanying documents - most likely by messenger. She knows what they are and I don't think she prevented any intended delivery for Josephine.
Yet, all the information is not available or clear.
So Josephine's letter was the original, and there was a reply addressed to Josephine with it, and Viddasala somehow knew that the Triumvirate's response was a carbon copy sent to her? For that to work, the original letter should be a carbon copy as well. Josephine should get her original letter back with response, should she not? So why would they send the original Inquisition letter to Viddasala? Why not send her carbon copies of both? And again, why did they send Viddasala a message giving to Josephine? Why not give Viddasala direct instructions in this case? Why send Viddasala any written message, for that matter? Why not just have the messenger deliver a simple order by word of mouth?
What I mean is, if the scenario in which it was authorized is to exist as a possibility, BioWare isn't going to withhold evidence that it is possible, or not show it to you. If the evidence exist, then it should be there. They would present it and let you draw a conclusion from it. As it stands, the evidence indicates that it wasn't authorized. BioWare isn't going to leave evidence out of this that would indicate that it was authorized. They aren't going to take evidence out and then leave it to the players to fill in the blank, because how can they fill in the blank with any kind of accuracy?
Solas isn't confused about who he's battling with in Trespasser.
Assumption. Other dialogue responses show that Solas is confused about quite a few things.
Here's what he says right before he turns the Viddi to stone and begins the ending dialogue with our Quizzy.
"Your forces have failed. Leave now, and tell the Qunari to trouble me no further."
So what? That may have even been a taunt. Telling her to return to her homeland, knowing full well that she can't. Thus goading her into attacking.
In any case, there is no evidence that Solas knows if Viddasala was authorized or not.
Viddasala's papers show us that what started was their plan to research the Veil. From that, the rest was born, including Dragon's Breath. Nevertheless, three years instead of two isn't a big difference, so my point stands.
But Viddasala lied. She claimed the decision was made when the Breach appeared. So my point stands. Viddasala was lying.
Also, her note to those questioning her in the Vir Dirthara was of course brainwashing to get those dissenters back in line.
Because the Inquisitor can always say 'no' and you can't gamble the entire fate of the world on thinking you will be able to turn someone.
Then it could be said that you can't gamble with such power staying in the hand of bas. Better to convert this bas to the Qun to ensure that the world is saved from the Breach and Corypheus, and also the South is brought under the Qun. No reason to wait, except that the South can't be taken because of a lack of forces.
If you consider the option of forcing them to, first you will have to take care of the Inquisiton's very big army and agents that would rush to defend their boss. It would be very un-Qunari to waste lives and resources senselessly when you can let the Inquisitor do their thing before you kill them all.
So why not lure the Inquisitor into a trap, capture him, hold him, and then provide reeducation? The Inquisitor often went out with a party of four including himself. Why wait for the Inquisitor's army to build up even more?
No, it wasn't. The South is weak, but as you say it's still strong enough to face an invasion. But if you had a way to make that weakness bigger? To tip the scales so much that total victory is possible? That's the point of Dragon's Breath, a chance you don't see in several lifetimes.
But Viddasala said the invasion would happen anyway. Dragon's Breath was only to be the opening attack. She said the way of blades was coming. She lied. There was never any invasion set up. Par Vollen would have needed warships waiting off the coasts. They would need basecamps and supply lines. They would need to move in fast before any generals could take over command of the courts that were attacked. That's assuming everything works. But at no time was any such force observed by anyone in the game. At the end it seems that the South accepts the official story that Par Vollen did not authorize anything. Most seemed to blame the Inquisition and Solas for provoking the Qunari.
With no changes in the scenario, the best way to take advantage of that is to focus everything on Tevinter to make it finally fall, knowing very well that the South is neither interested nor has the energies now to help them... which is exactly what they decide at the end of Tresspasser.
Toppling Tevinter has been the plan for ages. It was the plan in Trespasser. It will be the plan in DA4. Viddasala was trying to start a war with the South as well, without the Triumvirate's authorization. The Triumvirate on the other hand wants to beat Tevinter first, build back up, and then take the South one country at a time until they work their way down the board. It makes no sense to spread all your forces over the entire South before your main enemy is beaten. The Qunari need to take the land first before marching south.
No. The mages will always be divided between the Circle and the College in Trespasser's epilogue, either because they were already at the end of DA:I or because the differences they had weren't solved at all. So much for choices.
Divine Vivienne keeps the College in line, and the College itself is just a group of clubs within the Circles. Equitarian, Isolationist, Libertarian, Lucrosian, Loyalist. I think under Divine Vivienne there is never any "Bright Hand", and especially not if you side with templars. So the Circles can be restored. Full strength? Probably not. But again, those who fought now have more experience. And with the rebellion out of the way, they can focus on more productive endeavors. And in any case, there are young mages discovering their powers all the time. Within those three years, the ranks could have increased by the hundreds across all of the South.
