The Mane six clash (No Longer Updating)

When Kadence does a dark spell supervised by Luna and Celestia on holiday, the mane six find themselves. Then a new pony comes to town. What will happen? A/N:Im really sorry about not updating it. Ive been busy with school and family related topics. Also sorry if this is childish. I came up with the idea when i was ten. Also if you just started reading this is might be finished depending when you read it because this authors note has been put up the 30/10/18 and the last time i wrote in it 13/12/17.
