In the year 2028, the rule of Celestia and Luna has ended, and taking their place is a large, red, cyborg pony named Equilarsous. The cities and towns have become steampunk ghettos, filled with death and tragedy. The main six, holders of the Elements of Harmony, have scattered. Twilight works as the librarian of Canterlot, enjoying her job immensely. Rainbow Dash has joined the Equestrian Guard after learning that the Wonderbolts had abandoned their jobs and disappeared. Applejack is a poor farmer, barely keeping herself and Applebloom alive. Fluttershy fled to the forest after hearing of the new ruler, saying that he is an evil pony that will bring darkness abound. Rarity makes dresses for the rich in Canterlot, and is able to speak with Twilight nearly every day. Pinkie Pie is a baker who still lives in Ponyville.
After spending ten years unaware of the evil that is spreading thoughout Equestria, the main six are brought together again by a mysterious pony named Stormfax, who claims to be the disowned son of Equilarsous. He tells them that the land has fallen into chaos, and only the Elements of Harmony can revive it. But, after hearing this, Equilarsous will do everything to stop them from succeeding... even if it means the death of hundreds.
