So I'm getting near the end of the book and I still don't understand how Nynaeve got Moghedien to her. At the end of book 5 they fought in Tel'aran'rhiod and Nynaeve made an a'dam and captured Moghedien. And now at the beginning of book 6 Moghedien is in an a'dam with Nynaeve. How did she get there? Wasn't Moghedien with the black Aes Sedai? And I thought they said that whatever is made in Tel'aran'rhiod can't be brought into the real world?
