Corbie considered that question. Not because she hadn't been taught this, but because it had been so ingrained in her education that it was hard to pick out. "I was taught some about defending myself against spirits. But I ain't aethereal, so it's not a problem for me like it is for Felix. Not as much anyway. What I understand, I'll still do if a spirit's mad enough. But mostly... I was taught to keep myself safe from other wizards."
