  I think you are as wedded to a Mirror World connection as I am to ter'angreals built with a single mode of operation. :D  Quite possibly, lol. However, you are much more wedded to never allowing for Mirror World input in regards to these ter'angreal, which is odd, because it's such a fruitful source of data.  Egwene is a Dreamer. Dreamers and Dreamwalkers can tell the future from T'A'R alone. Egwene has never knowingly or deliberately sought the interface between T'A'R and a Mirror World, but she has had Prophetic Dreams.  This is such a confusing statement. T'A'R is a third constant present in ALL WORLDS.
