-Skyrim: Dawnguard Crossover-

Twilight Sparkle, an initiate of Princess Celestia's elite 'Dawnguard', is chosen by the divine pony as a leader for Equestria's future. Her first task is to train with a master Changeling hunter named Zecora. However, Zecora herself goes missing shortly before Twilight's arrival in Ponyville, leading to a chase that takes her deep into an underground ruin of the Everfree Forest. There, she interrupts the attempts of a previously unseen type of pony to resurrect one of their ancient kindred from a heavily sealed sarcophagus. History is quickly unravelling, with the young Twilight at the centre of an oncoming darkness.
