Once upon a time, ponies had friendships. Once upon a time, they cared for and cherished each other and strove to follow the virtues of it. Once upon a time, the Elements of Harmony were united under the flag of the Royal Sisters, Celestia and Luna.

Once upon a time, that all existed. Now, all that's left of that time is a raging, brutal war led by the six mares who once brought peace and unity to Equestria, the virtues they once valued lost in the blood.

Set in the universe of Equestria Divided.
