Twilight is the new princess of Equestria and lives in the Canterlot Palace with Spike to assist her, Rainbow Dash and Applejack have both met fine stallions and started families of their own, Rarity has moved to Canterlot to be closer to her business, Fluttershy continues to take care of her animal sanctuary with occasional help from Discord, and Pinkie Pie and Cheese Sandwich have started a relationship and work together as traveling party planners.
These are the journals of the highlights of their lives tying in with and eventually leading up to the beginning of "Flurry Heart's Story," a fanfiction idea I have had for a while now that takes place about 8 years after Twilight's coronation and the defeat of the villainous "Trio".
