"If she's a healer of course she's grey." Lara smiled. "Using light magic on cancer or parasites is just bad. And that would be wonderful. I'm having to work it all out as I'm going along." She paused. "But I'd say about half of what's written in those books of yours about light magic is deliberate misinformation by light witches to make sure dark ones try to fight them in the least effective ways possible. With just enough in there that's true to both be misleading and give pointers for light witches."

She laughed. "Especially the advice to break a light witch by destroying them in front of as big an audience as possible. Or to neutralise them by taking them to somewhere chaotic like a waterfall or an active volcano."
