So, the scenario of this is that after PC's and SA's wedding, QC came back, and thought she killed Cadence, and then shining brand back Cadencewith the power of love. Then, everypony grows up, SA and PC have Princess Skyla (yeah! I'm going with it!). So, Twily took over Celestia cause Tia died, so did Luna, so, Twily, since she's the rainbow princess now, is also taking over for Luna. Pinkie and cheese got married, and were silly and named their kids, filly, Pinkie Sandwich and foal Cheese Pie. (And never knew he was named after a shipname.) applejack now owns her own farm, Fluttershy lives sadly alone, rainbow dash is captain of the wonderbolts cause spitfire quit, rarity is now an official designer, spike moved away (but isn't sad like flutters) Derpy is a bakery worker. The CMC got their cutie marks and are still the best of friends.Because we start at the beginning, somepony is still Tia and Luna.
Note: you can be several ponies.
Pinkie sandwich: me
And a misquote:
LETS GO MARRY SHINING ARMOR!
No, it's just a joke.
