I'm still cheesed off that Robert Jordan invented Balefire which erases people from existance only for these 'dead' forsaken to come back thanks to the Dark Lord's intervention.
Massive, massive cop-out there and completely devalues his series IMO
I don't know of any Forsaken that have been returned after being singed with Balefire off-hand, but I can see how that may work.
The Chosen, I believe, were stuck in a limbo like state until freed by the Dark Lord. Unless the Balefire was strong enough to wipe them from all existance, unlikely as they are quite ancient now, all that it would have done is erase thier involvement in this current Age.
The Dark Lord would then be able to release them upon the world again, or rather the first time again.
Could be wrong, but that is just a thought.
