I still wonder, how exactly Egwene and the Seanchan will work together, as Egwene's Dreams suggest. In my view, the Prophecies could convince Egwene to make a truce with the Seanchan.

In TGS, ch. 16, Egwene cites the Prophecies of the Dragon:

"The Karaethon Cycle, Elaida, [...] When you had Rand locked away to be kept 'secure,' had he yet taken Illian? Had he yet worn what he was to name the Crown of Swords? [... ]And how did you expect him to fulfill the prophecies if he was hidden away in the White Tower?[...] How was he to cause war, as the prophecies say he must? How was he to break the nations and bind them to him? How could he 'slay his people with the sword of peace' or 'bind the nine moons to serve him' if he was locked away? Do the prophecies say that he will be 'unfettered'? Do they not speak of the 'chaos of his passing?' How can anything pass at all if he is kept in chains?"

This scene shall certainly remind the readers of those Prophecies, probably in particular the importance of the Tinkers and that Rand will bind the Nine Moons to him.

But it also demonstrates that Egwene knows the Prophecies quite well and thinks that they have to be fulfilled. Considering this, isn't it possible that Egwene will try to make peace with the Seanchan, if she learns that the "Nine Moons" actually refer to the Seanchan Empress and that it is apparently important that Rand binds her to him.

It would be similar to Rand's aim, after he learned that Tuon is the Daughter of the Nine Moons in KoD:
"The Prophecies say I have to bind the nine moons to me. I only understood what that meant a few days ago. As soon as Bashere returns, I'll know when and where I'm to meet the Daughter of the Nine Moons. The only question now is how do I bind her, and she'll have to answer that."

Plus, Egwene actually knows from her Dreams that she has to work together with the Seanchan:
"Rand confronting her [Egwene], and the women with her, and one of them was a Seanchan.

And:
"She [Egwene] was struggling up a narrow, rocky path along the face of a towering cliff. Clouds surrounded her, hiding the ground below and the crest above, yet she knew that both were very far away. [...] Abruptly, the ledge dropped away from under her with the crack of crumbling stone, and she caught frantically at the cliff, fingers scrabbling to find a hold. [...] Suddenly a woman appeared, clambering down the sheer side of the cliff out of the clouds, making her way as deftly as if she were walking down stairs. There was a sword strapped to her back. Her face wavered, never settling clearly, but the sword seemed as solid as the stone. The woman reached Egwene's level and held out one hand. 'We can reach the top together,' she said in a familiar drawling accent."

Since Egwene knows that her Dreams come true, this could convince her to try to make peace with the Seanchan before TG.

On the other hand, Tuon might also get a Foretelling from Elaida to convince her that she has to make peace with Rand & the WT in order to defeat the Shadow. Besides that, the Seanchan will probably soon realize that sul'dam (and thus Tuon herself) are channelers as well. This should fundamentally change their society.

What do you think will convince the Seanchan and the Aes Sedai to make peace?
