The Pinnacle of evil.

Pinkie Pie was enjoying her latest party, well, more of an after-funeral-party but it was fun nonetheless. It was on such a grand scale that it could even rival the Grand Galloping Gala! Of course she couldn’t have managed it on her own; she had the help of her favourite party pony, Cheese Sandwich, and the princesses as well!

Meanwhile, a certain princess had just returned from her duty of raising the moon, and was just about to re-embrace the party, when a guard charged up to her.

“Your highness!” The guard uttered through his fear. He presented a black envelope. Luna recoiled as it was thrust into her face; she recognised it. After a few moments of trying to remember the more recent things (not being banished to the moon) she remembered that Fluttershy had written to her about a similar one her friend Discord had received. She turned and read the letter, before dashing off to her room to sob.

A while later Princess Celestia noticed the disappearance of her sister and went looking. Several members of the royal guard, including Shining Armor himself insisted she was accompanied, but she declined every request, it might be something personal. She started down the corridor when she heard sobbing from her sister’s bedroom. She pushed open the door to see Luna face down on her bed, wings folded, room darkened. Only the light of the door lit them both, before the faint blue glow came from the younger.

“Luna?”

Luna screamed.

“Luna?” Celestia repeated, more urgently this time.

Luna extended her wings, spun, and let the room fill with more blue light. Celestia slammed the door shut just in time for the bolt of blue magic to miss her skull, and ran. The door burst open and a blue blur knocked her to the side, which soon went on to terrorise the rest of the party. Celestia got up and followed the princess, and were soon fighting above Canterlot Castle as they had done thousands of years ago.
