I suspect Verin was concerned about what Rand would do to the people in the tower. With a ta'veren downstairs, the AS would suddenly have found themselves unexpectedly spouting secrets and the like. Imagine the chaos if Elaida were to suddenly start speaking the full truth about everything for example. Now imagine that happening to every AS.

I think if Moridin put Rand in a cave with no people, and contained him well enough (Cuendillar chains for instance), even ta'veren would find it VERY difficult to free him.

If ta'veren could do anything, there would be no point in the shadow trying to win afterall. It is a big help for Rand certainly, but its not the ultimate answer to everything.



Assuming the male a'dam is released the same way. Though I admit the point is moot. With so many AS and Asha'man, Rand would have been shielded and Semirhage recaptured if she had actually tried to use Rand to fight.



It is true that the bond would have revealed where Rand is, or atleast his general direction. But there is a big difference between that and actually freeing him. If Moridin got his hands on Rand, he would certainly arrange for him to be well contained. Freeing him would not be easy.

And that is assuming that nothing permanent had been done in the meantime. What if he had been mind-trapped. Or forcibly turned. Or if Moridin had decided to hack of his other hand (and legs too) to make him less of a threat while still keeping him alive. Or something.

Rand channeling TP was bad. But if he had been taken to the blight, it would have potentially been much MUCH worse.
