Final Crisis of Equestria

The king's energy passed through the world's natural gems and everything started to glow brighter. His highness looked at the Pony who summoned him "Princess Twilight Sparkle, the world is yours." and then the King vanished.

As all the ponies breathed a sigh of relief, Rainbow Dash was the first to speak up, "Whatever happened to Gilda? It was her who put Trixie under enough duress that she became the host for Tirek (or Nightmare?) but I don't think she had any idea what she was doing, none of us even knew this kind of evil was possible."

Celestia had an answer, "Gilda and Trixie will be fine. I considered banishing them to the moon, but honestly I think I'll let the Sea Ponies serve as their wardens.

Spike, returned to his typical stature, gazed up at the sky, the entire sky was a repeating pattern of rainbow from horizon to horizon, and hundreds of nobel dragons filled the air, "Look, the dragon horde are taking the King's Energy too the source of Magic." And as Equestria was left to rebuild, the kingdom never would never know that kind of corruption ever again.
