Ohhh, I'm rereading Mystra's entry in the Sword Coast Adventurer's Guide... and this detail:
This means Gale was punished for trying to restore and preserve what he thought was a lost piece of Mystra's magic. Gale being Mystra's ex-lover put aside. He as her follower, she his goddess, was punished for attempting to do the one foundational rule of her faith.
I'm seething and so sad at the same time.
Edit: I used the word punish loosely, as in, toxic/abusive people will take any small mistake or action and twist it into something they can take advantage of. This post was also largely from the stand point of a toxic deity rather than a toxic partner, but both takes are valid here. Especially with the, “you didn’t stay compliant so now I’m giving you the silent treatment” part of it—from a god and a partner perspective.
