I'm sorry if this has already been asked and answered. I'm new here but I searched through the archives and didn't find an answer. My question concerns Dilaf's wife and the spell that disfigured her. We know that Dilaf has something in him that causes AonDor to go wrong. Is it possible that his proximity (possibly even being in contact with his wife) during the invocation of the spell caused it to fail in such a spectacular way? Both the transformation of Dilaf's wife and the Shaod seem to be alteration spells (although one is based on the wisdom aon and the other on the change aon) that went wrong. Actually, because we never see what causes the Shaod it may also be or have an aspect of the wisdom aon in it. Wisdom, after all, is a famed trait of the Elantrians. It may even be possible that Dilaf's interference caused some kind of buildup in the Dor (like the one that Raoden experiences), a buildup that eventually caused the earthquake which in turn caused the chasm and the Reod. I understand that Brandon Sanderson has already stated the the chasm was not natural and this is the best theory I can come up with.
