"I'm afraid I can't do that. Not unless, of course, Circle Daybreak were to change what they define as dark magic."

Something that won't happen, nor is she asking for that consideration. It is merely a line in the sand. So long as the thing she needs to survive -- and that others may yet need as well -- is considered to be forbidden magic, she cannot renounce what Circle Midnight stands for. They may have much to do within, but she won't abandon them.

Especially not without far better reason.

"They have stood by me, even when I have been wrong. I will not abandon those in my Circle."
