To those who walk the dreams of others, there are three rules to follow. First the dreamwalker must avoid most, if not all, contact with the dreamer. Second, the dreamwalker must not alter the dreamscape in any major way. Third and most important, the dreamwalker must not lose grip on what is real and what is not. As long as the dreamwalker is roaming in another's dream, neither can be woken no matter what is done to them. Luna lived by these rules her whole life. Or so she thought.
