Midnight Sparkle, Nightmare Moon, Daybreaker. Every one has a dark side. Everyone has a piece of themselves that they bury, but with Princesses, these personas are given form, and life, and minds of their own. Powerful Magic has a will of its own, and the Princesses are more powerful than anyone else. Our Princesses must face these darker selves, if they don't... Cadence fears for the future of Equestria.

But she's just the Princess of love. Against the might of the sun, and the moon, and the stars, what could she possibly do to help?

Well, a little self-love can go a long way.
