I dont know if it has been discussed before, but recently I was re-reading the Eye of the World and came across the instance in the Blight where it seems that Moiraine was able to unravel a weave as Aviendha is able to do later in the series.

(Moiraine opened her eyes and started down the hill. “For me to remove the last vestige of what I did here last night. The residues would have dissipated on their own in a day, but I will not take any risk I can avoid now. We are too close, and the Shadow is too strong here. Lan?”)

Is this an ability that she has that is unique in the White Tower?

Discuss!
