If laughter, kindness, generosity, honesty, loyalty, and magic are elements, what is Harmony?
Years of peace is suddenly shattered by what seems like an invincible power that arrives seeking an individual whom he makes clear, is actually the aspect of harmony. Giving a brief nugget or two of knowledge on the subject of aspects and elements, he offers Equestria a chance to rid itself of him, but should they fail he promises to kill every last thing that draws breath on their world as he continues to seek the aspect of Harmony. Can anypony stop this strange newcomer or will everypony have to pass his tests and complete his game to save all of Equestria?
