I have a feeling that your argument is moot. Whether or not Mesaana could be healed to regain her sanity, the Aes Sedai will probably execute her for her crimes. It is tower law after all. In addtion, lots of the storylines in the Brandon Sanderson books are a little out of sequence due to...
Who's to say exactly how powerful the Chodan Kal actually were. I believe that when they destroyed an entire city in the age of legends with balefire... it was multiple channellers using multiple balefire streams. (at least that's the impression I got) It wasn't like one massive column of...
We'll just have to disagree on that one I guess. Killing darkhounds and Chosen with balefire seems worth the risk to me.
It brings up an interesting question tho.
When there are several packs of Darkhounds showing up at the last battle, how will the forces of light deal with them...
Possibly, yet the point is that I'm pretty sure the amount of power used to destroy Graendal's entire fortress in one shot was more powerful than what the circle of Aes Sedai that I proposed could produce.
That horrifying amount of power and the large number of targets affected by it was...
A single column large enough to encompass Graendal's entire fortress? I'm not certain if he used ALL the power at the Chodan Kal's calling ability, but he certainly used alot.
Henry, he's not saying that it isn't possible. I think he just really hates the idea of messing with time.
It's taking a chance, but I think erasing a Chosen for a few days, possibly close to a week would be more of a gain than any potential loss. Balefiring Graendal's entire fortress with...
How about get together the most powerful circle of Aes Sedai they can with the best sa'angreal available, then balefire her with the biggest stream of balefire they can possibly make.
Perhaps some evils will be undone over the past day or two.
