Once upon a time, in the magical land of Equestria, there were two regal sisters who ruled together and created harmony for all the land. To do this, the eldest founded an order of knights, with the youngest as their leader.

The Order of the Holy Knights, as they were called, each member possessed the strength to match an army and amazing magic powers. Even after the loss of their leader a thousand years ago and to this day, they continue to carry on their duties without fail.

For the Holy Knight apprentice Twilight Sparkle, what started as her first official mission will soon become a war against dark forces that threaten to devour all of Equestria.

A humanized retelling of MLP: FiM borrowing several elements from Nakaba Suzuki's "Seven Deadly Sins" manga.

Twilight Sparkle is the personal student of Princess Celestia, principal and founder of the Eos Dueling School. After her warnings about the possible return of an ancient, evil being are dismissed, Twilight is instructed to go to Ponyville and evaluate a potential Duel Monsters school. There she will meet an unlikely bunch of duelists.

Applejack, a farmer with high level dueling skills. Rainbow Dash, who doesn't know the meaning of the word "defeat". Rarity, who wants to dazzle the world with her dueling skills. Fluttershy, a timid girl who can see more than she lets on and Pinkie Pie, an energetic girl who wants to make others smile with her dueling. They will all have to work together to face the return of the Maiden in the Moon.
