Eight dark realms. Eight holy kingdoms. Each has its opposite, but who can truthfully say which ones are evil? Yoji is a child of the shadows, a demon of the darkness, and a prince. He wants to live free from responsibility but can't as long as he is the son of royalty. One day, on a diplomatic trip, his father discovers that changelings are amidst an allied kingdom. From there, Yoji travels to foreign lands and broken kingdoms, always ready to do what's right.
