One thousand years ago there were six pony races: The Earth, the Pegasi, the Unicorns, the Crystal, the Shadhavar... and the Dragonponies, the Longma. With bat wings, draconic eyes, and reptillain frills these creatures were told about in myth and legend as tricksters and monsters. The demonic minions of the bogeymare Nightmare Moon. But this lost race has returned, a menacing force appearing far to the north. Twilight Sparkle decides to investigate and ask the Princesses about the details, but she soon finds herself responsible for an empire of monsters, worshipping Twilight as the successor to the Mare in the Moon. How will she handle the pressure?

Percy Jackson and Annabeth Chase have gone through a lot. They fought the Minotaur, Medusa, a Manticore, the Chimera, Kronos, and even Arachne, the Spider Queen. It was during this last fight that they recovered the Athena Parthenos, a sacred statue that would help secure the demigods' victory over Gaea and the Giants, but the unexpected happened: the floor gave away, and the pair fell all the way down to Tartarus. The first thing they noticed, was that a large mirror, that no monster would approach, not even for some tasty demigod blood. They were trapped, and the only way to save themselves, was through that mirror. What was on the other side, however, was even wilder than they ever thought possible.

(Added romance tag and made story "Teen" for planning on future chapters, and romance mostly in post-story Extras section.)

(Being a big Percy Jackson & The Olympians fan, I couldn't help but notice that Tartarus existed in Equestria, according to Twilight. This story recounts the events of Percy and Annabeth's journey into the other side of the Pit, and beyond.)

Twilight has discovered a new spell to use in tandem with the Elements of Harmony. Its intent is to reveal more of the mysteries behind the artifacts. Yet once the spell is cast will the mane six be able to deal with the consequences? What will they learn when they come face to face with the very virtues they claim to embody? The Mane six will have to face their greatest challenge yet. The Elements of Harmony themselves.
