After Nightmare Moon and Celestia disappeared during their fight the void of power needed to be filled, so who better to do that than the noble ponies that were already governing over regular ponies. After all, it's only till Celestia or Nightmare Moon returns, that was almost a thousand years ago. A lot has changed. the elements of harmony and what they represent have become objects of myth. Due to the lack of harmony in Equestria, a changeling myth has reawakened and he has a plan. Granted he doesn't have a good plan but it's a start. With help, King Chrysilix The Scarred King of the Changelings might just be able to save Equestria before all of the Changelings starve.
