During a friendly, casual visit to Canterlot Palace, Twilight asks Celestia a question many ponies have likely pondered for years.

Why is she a Princess and not a Queen?

And Twilight receives her answer in the form of a story, long lost to the passage of time. A story about the true Queen of Equestria, an alicorn known to be as the first ever created. Her name, Queen Athena, the Queen of Harmony.

Have you ever wondered "Where did Spike come from? Where did Celestia get his egg?" Well, what if that question was a mystery no longer? When visiting Princess Cadence, Shining armor and their little baby, Flurry heart, Spike stumbles across a particular crystal statue in a closet in the Crystal castle. When he asks about it he discovers something that prompts him to run into the arctic north without telling Twilight.

There he meets a stranger, someone he never thought he would in the ruins of the Dragon's Quarry.
