There might not be a lot to discuss here. I noticed there is nothing new about Moghedien and Balthamel (a.k.a. Halima/Aran'gar) in The Gathering Storm.

Any speculation on what Moridin has Moghedien doing for him?

Any idea where Halima/Aran'gar fled to? My guess is she would want to try to reestablish an area of strength, but where could she go?

With Semirhage gone, nobody is guiding Fortuona, may she live forever, and I do not see the Forsaken leaving someone with the power that Fortuona has alone for very long. My guess is that someone among the Forsaken will attempt to control Fortuona in the near future.

By the way, is General Galgan actually Demandred?
