Well, you who have read POD knows what happened to Faile and Berelain. If you go back to when Morgase was a prisoner in the fortress of light(or what it name now was), then you know that Pedron Niall said to Morgase that her step son Galad was in the north Amadesia. One of mins viewings said that Berelain would fall to a man in white so it all point on that at least Berelain will be saved by Galad and the Children of light.
