A Lunatic takes over Equestria and it's not Discord or Pinkie Pie but has very powerful magic that rivals both Celestia's and Luna's magic

Trixie is somehow an Alicorn now

Celestia is missing and her sister Luna has been kicked out of Canterlot by somepony she knows

oh also somthing is wrong with Ranbow Dash Rarity and AppleJack which was caused by the CMC's
