Frosty chuckled and turned away, taking a few steps towards the throne. “Alas, killing you would be rather unwise of me, as I still need you. You see: these ponies still hold you very dearly and it would be quite difficult to get them back under control if you were dead.” He explained. “So instead, I would like to keep you as the public face…”

“I will not become your puppet!” Celestia shouted. “I will destroy you as soon as I get the chance!”

“Tsk tsk tsk, Celestia, it seems you didn’t get the memo.” He mocked, turning back around and coming back towards her. “If you kill me, then everypony in Canterlot will die. If you defy me, then everypony in Canterlot will die, including you and your sister.” He threatened, taking a look at the still-unconscious Luna. “But if you do as I say, then Everypony will get to continue their lives as normal.”

Celestia didn’t say anything anymore and only let out a defiant growl.

When the Elements reached Canterlot, they found that indeed a large crowd had gathered. However, they didn’t seem to be rioting, but rather listening to something. It wasn’t long until they heard what they were listening to, as princess Celestia’s voice echoed over the plaza.

“… and therefore I have to thank every single one of you that you have helped free me from the daemons that possessed me.”

The Elements gasped as they heard this and rushed into the crowd.

“And as a sign of my utmost gratitude and as a precaution that something like this will never happen again, I have decided that I shall hereby formally appoint Sir Frozen Blood the position as Royal Advisor.”

The crowd cheered and Rainbow, Applejack and Pinkie joined in. “See, Twilight? Frosty wasn’t an evil character at all. The princess herself has said so.” Rarity said to Twilight, who was looking at the scene with disbelief.

“But… Celestia wasn’t corrupted… was she?”

Author's Note

The shortest Ending of the three... would also make for a more or less decent basis for a sequel, but I like the Chaos ending more.
