My theory is Gale is getting sacrificed at the fist possible opportunity and if I get the orb to maybe to anything with fine, if not then also fine. End of Gale's story. And frankly, imo he deserves nothing better. Mystra is not an evil deity and no valid reason is provided for his betrayal other than he was greedy and thought he could replace her. I definitely wouldn't trust him and have no intent to help him.
