  Also, it is clear that Egwene's trips involved information she did not bring in with her:  TITLE: Dragon Reborn CHAPTER: 00 - The Price of The Ring There was an Aes Sedai at her elbow, a woman with Sheriam's high cheekbones but dark hair and concerned brown eyes, and the hand-wide stole of the Keeper on her shoulders. Not Sheriam, though. Egwene had never seen her before; she was sure she knew her as well as she knew herself. Haltingly, she put a name to the woman. Beldeine.  It's obvious that this information came from a future mirror world through T'A'R connection to MW's.
