Valarinth understood what Tyr was saying, though as she returned to the classroom she realised that something was surfacing within the school that had the essence of her magic...no, it wasn't her magic...it was something that had been created by her darker side as a final insult before he'd been assimilated back to form her original self.  This wasn't a good sign, but there was little she could do except to wait it out until the end of class.  Maybe then she'd discover what was going on within her school.
