Before the Servants of Shadow, before the Night Guard, there was one pony who took it upon themselves to protect and serve Princess Luna. This pony was an extension of Princess Luna, completely loyal and devout; carrying out all of Princess Luna's orders without question nor hesitation. This pony operated in the shadows with surgical precision and unstoppable force. This pony's identity is known only by the diarchs. To the rest of the world, the pony was simply 'The Darkside of the Moon," an enigma, legend, a story told to bad colts and fillies to keep them in check.

Much thanks to RarityEQM for allowing me to use her OC's from Moon Unit Zappa.
