Oh interesting. Moiraine saw all of her potential futures when she went to Rhuidean. I wonder if that means that the three different rings DO do something different, with the one Moiraine went through showing the future and the one Rand went through showing memories of ancestors, or if men and women see different things stepping through them. If the former is true, I wonder what the third ring shows? I would think the present, since one shows the past and one the future, but that would seem odd.
