Vi barely noticed when her whispering classmates suddenly quieted. A squat Sister tut-tutted and the wall shimmered, becoming opaque white like the others in seconds. Without preliminaries, Sister Gizadin began: “There are three reasons glamours should be used sparingly. Anyone?” Not a girl made a move. “First, glamours are unpredictable. Second, glamours are unnatural. Third, glamours are unappreciated.

“Unpredictable. First, a glamour may affect only men or only women or only children. Second, a glamour may affect some people much more strongly than others. Third, a glamour will attract people according to their own predispositions. It may impart, particularly in men, an overwhelming sexual desire for the caster. Or it may impart a slavish servitude, where the person finds in you every good thing they could imagine. Or it may impart a simple attractiveness and persuasiveness.

“Unnatural. First, a glamour can operate by exaggerating a quality you already have. That could be exaggerating your inherent attractiveness, or it could exaggerate people’s perception of your courage or honor or strength, or it could exaggerate a bond such as friendship that you share with the glamour’s target. Second, a glamour may feign the attractive features of another person. Third and most powerfully, a glamour may tap the subject’s mind for what he finds most attractive. One man might say the caster was blonde and blue-eyed whilst the man beside him would swear she was buxom and green-eyed. But this type of glamour is unusual and challenging to use. And obviously, if the two men talk after that maja leaves, they will notice the discrepancy.

“That leads us to the third reason glamours should be used sparingly: Glamours are unappreciated. First—” she stopped, irritated. “Viridiana, stop fidgeting. You have a question?”

“What if you can control all that?” Vi asked, standing up and putting her arms behind her back, feeling like a child. “It’s not that hard.”

All the girls in the class looked at Vi as if they couldn’t believe she’d dared speak.

“Do you really wish me to believe that you have natural mastery of one of the more difficult relational spells?”

“I didn’t say mastery,” Vi said defensively. The truth was, she was still off-kilter, the thought of having to go talk to Elene hanging over her like a death sentence—which, she realized, it might actually be.

“Unless you’ve actually cast this spell, sit and be silent.”

Vi paused, then scowled. “I have.”

“Oh? Pray tell.” Sister Gizadin gave a condescending smirk.
