Does Gawyn know how to use the blood rings?

Nope. Or at least, he hasn't figured it out yet on-screen.

I was wondering why he was carrying them. Who would he use one on? His mother has been avenged & he seems to have made peace with Rand in his head.

He will use it to assassinate the Seanchan empress, Fortuona. When he takes the blood rings from the bodies he thinks to himself that something must be done about the Seanchan. From Avi's trip through the pillars we know that Fortuona will be assassinated at some point in the future just before some compromise is reached. With all the security around the empress killing her won't be easy unless you have an advantage such as the blood rings. And killing Fortuona just before something can be worked out between the Seanchan and the Aiel seems like something Gwayn would do,

I don't know if it's possible to ward somebody else's dreams.

 

Moiranne offered to ward the boy's dreams pretty much through the first half of EotW

 

She didn't actually do it and we don't know that she actually could.

EotW depicts Moiraine displaying a lot of powers that are contradicted in later books - she blasts out a Waygate, unweaves, etc.

RJ worked out his "rules of OP" more carefully after EoTW and TGH. I'd be wary of accepting an EoTW reference without confirmation from later books / RJ quotes.

The supergirls using Moggy's own power to ward her off is an interesting suggestion - but it's never mentioned at all.

Not even a reference, from Moggy's PoV when has her repeated dream of rescue and abuse.

I know there is no evidence to say that the girls warded Mog's dreams. I only offered it as a suggestion as to why she doesn't enter TAR or talk to other forsaken in her dreams. This situation is just one of those plot holes that doesn't really have an answer.

Or they could have use Mog's own ability to ward her dreams with the a'dam.

Unrelated question.

Moggy is a Dreamwalker like Egwene. She has no need to use ter'angreal or to enter TAR in the flesh. Like Egwene when she's held captive in the WT, Moggy could communicate with whoever she chose to, and even to use OP in TAR, while being held in Salidar.

Even though the Supergirls know that, how could they cut her off? Did they even try? IIRC, there are no references to this.

Also, Moridin is a dreamwalker and so is Cyndane. Halima is a weak one but close enough physically to track her. Even if Moggy is too ashamed or fearful to contact them, why wouldn't they find Moggy's dreams and debrief her, forcibly if required, before she's rescued?

It makes the whole prisoner sequence in Salidar a little more difficult to believe.

 

I considered this, originally, just after tGS. I offered the unlikely scenario that Egwene could pull the captured Aes Sedai into the dream and sever them--severed they would be free of the a'dam, and the torture it brings. They would also no long risk the revelation of gateways, and they may well in time be healed.

 

And then a simple problem occured to me--what if the a'dam blocks acces to the dreams of its victims. Once this occured to me, I recalled exactly the situation you describe--Moghedien successful long term imprisonment under the a'dam despite her ability as a dreamwalker.

 

And that's what I offer back to you. Dunno if it helps.

 

May be worth asking Brandon? The a'dam is definitely a possibility and it would work - except that there are too many dreamwalkers who can't channel, hence immune to the a'dam. So it would have to be something convoluted like a channeler-dreamwalker can be blocked from TAR by using an a'dam while a non-channeler dreamwalker cannot!

 

 

It's actually possible that being in a link keeps you from touching the Dreamworld. As in the part of you that reachs to the Dream is instead reaching to clasp someone elses hand. Or is, you know, lock in a chain--if you get the gist.

There is no proof that the a'dam prevents access to TAR but wards can. In book 5, I believe, Egwene is trying to look in on Rands dream's trying to find a way around his wards and she speculates that would be able to touch TAR even accidentally though such strong wards. If the girls put an inverted ward on Mog every night to "protect" her dreams and keep the other Forsaken out so she would not be able to communicate with them this may have also stopped her from reaching TAR.

In an unrelated question, why did Egwene's AS apparently just forget about the Red's setting up False Dragons? I know is was a lie by Suian and that they stopped showing Logain off to other Nobels when he was healed. But this seemed to have been completely forgotten in the last few books and when the tower is reunited no one even mentions one of the main reasons for making the Salidar sisters march on Tar Valon. Then there is also the foreshadowing and implication that this may actually be true. From the first book Ish said that the Tower had used false dragons in the past and in later books, 8 or 9, when we are given a POV from the BA hunters one of them makes the comment of how some of the reds refuse to acknowledge the rumors of setting up false dragons but don't deny it.
