Well this strange object was mentioned way back in the prologue to book 1. It is also the namesake of our most gracious host. I believe that this mysterious object is still in the story today. Let me explain. Shortly after Egwene receives her twisted stone ring she is looking at it in her room with Ny and Elayne, when Lanfear, masked as Else Grinwell, is caught gaping at the object in her hand. Now I've read the books a few times and I've always glazed over this passage, because so much other stuff was going on. But what in the world could cause one of the forsaken to gawk? Not, much. Now why hasn't she taken it, maybe it does some thing completely different for men (no male channeler has ever had it in the books) The only other clue I have to this is that Elayne, the modern day master of ter'angreal, can't copy it exactly. Which means that perhaps it was made by a male and a female in the AoL. this is a really far out theory I think but I don't think that RJ would throw insomething like the Nine Rods of Dominion, and the Ring of the Tamyrlin, and not use them again, especially if he introduces to us a strange ring ter'angreal... BTW I think the one of the 9RoD is in the WT (Siuan used apowerful sa'angreal when she healed Mat, and I think that's one of them) Peace favor your swords.
