She sends Elminster to stabilize the orb that she herself destabilised just prior to that. My point being, how could the weave eating mechanism of the orb have begun to falter, when it was Mystra that had put it all in place ? Was her original work so sloppy that it would "wear off" in time ?
Maybe something potentially significant happened to Gale. Like, being implanted with a magically altered illithid tadpole, which is then subdued by a magical alien trapped inside a box that is being manipulated by an illithid mastermind.
But what are the chances of that?
