Norine was greedy for power and hated Alviarin for it but more than anything thinking like a forsaken, would Mesaana ever bow to Alviarin? also Norine is no one really in the tower, shes not in a position to pull strings, Mesaana as a character would have to be in a place where she can sway people to what the dark one wants, I bet shes a sitter and one of the new ones, a position of power left open and taken in or the same way as Semirhage took hers! im sure of it and most likely the one i mentioned, Norine is a nobody who thinks she should have power but cant! In short Juilaine is in a position of power and only got it recently by a very unusual route while norine...well shes a white who has no power what so ever! to place her in the white makes no sence unless she just wants to hide and only hide....is mesaana not trying to cause chaos? I don't believe for a second Norine is the one.
