It got odder still, though. There was, close to a thousand years before this book had been written, some sort of war between the two sisters over the throne. One of them, Luna, had started calling herself "Nightmare Moon". Apparently, she wasn't getting enough attention on the night shift, or something. Erin sympathized a little, and gave the princess points for picking an awesome-sounding super villain name. The book certainly had no trouble branding her as "Wicked" and "Evil", proving once again that history was written by the victors.
