Their Royal Highnesses Princess Twilight Sparkle, Princess Mi Amore Cadenza, Princess Celestia and Princess Luna gather for cake and tea with the living embodiment of chaos. Discord tells everything there is to tell about his past - when he came to Equestria, how he first met Celestia and Luna and how he attempted to make their lives harder - with some special emphasis on the parts that make Celestia vaguely uncomfortable. He loves those parts.
