One mare was forgotten in the tales of King Sombra, but her presence none the less brought terror in it's own right. That mare has returned, but can she earn redemption under the guise of the moon? Princess Luna takes a chance on a mare that had disappeared from the Crystal Empire 1000 years ago, and assigns her under the Head of the Lunar guard.

This is Bloodstone's story, and there is much she will have to learn under the laws of the Equestria Nation.
