Emily's golems are finished and she has them sent back down as the turns to Agnar.
As I said before, the mages guild made a deal with Rhena they wouldn't oppose her. Teleporting you guys to stop her would definitely count as opposing her, which would then prompt Rhena to attack the guild. Vune believes that the guild would win in such a fight, but such a fight would weaken the guild and she wants to avoid that. That being said, she has no obligation to stop us from fighting her now that we broke free. Vune is a woman of her word-she promised her guild wouldn't fight Rhena, and to lock Valorim up and she did both.
