At last, Fassbender's plan was almost complete. He had captured all the ponies of Equestria and imprisoned them on Demon Island. All was left to do was wait until his demon army were done demolishing and rebuilding every piece of land in Equestria for his own version of his kingdom, turn every pony into demon slaves, and make Princess Twilight his queen.
"My life-long dream is finally coming true after so many years." smiled Fassbender to his henchmen as he sat in his den on Demon Island and looked through a bunch of monitors showing his demon army crushing Equestria. "Once my minions are done turning Equestria into Demontopia, the capital of my empire, I can then marry Princess Twilight and make her my queen. After that, we'll begin our new life, turn all those ponies into our slaves, and then all our problems will be over."
Fassbender gets out of his chair and walks out of his den followed by his henchmen. Fassbender and his henchmen come to a hallway where prison cells are perched on each side. They are all filled with ponies yelling and bad-mouthing Fassbender.
"You three," said Fassbender. "See if you can tone down that noise these fools are making."
"Yes, sir." said Luther as he takes out a microphone and starts talking to the ponies with it. "Uh, attention, attention, may we please have your attention please. Mr. Fassbender requests that the noise you are making gets toned down a little."
The ponies don't listen and can't hear. They are making too much noise. Fassbender grabs the microphone away from Luther.
"Give me that!" snarls Fassbender "You're doing it all wrong. You need to do it more like this. ALL OF YOU, SHADDUP!"
Every pony becomes quiet.
"I like it when I do that." laughed Fasbender
"Fassbender, leave them alone!" shouted Twilight who was in none of the prison cells but in a cage that was hooked to the ceiling.
"Well then what are you going to do about it, Princess Twilight Sparkle?" chortled Fassbender "Have yourself and all these ponies use your magic against me? You know that's impossible since I've gotten rid of all the princesses of Equestria, and without them magic is unable to work in this world."
Fassbender laughs and laughs as he and his henchmen leave the prison cell hallway. After they have gone, Spike starts coughing uncontrollably. Twilight's friends step back a little except for Rainbow Dash who hits Spike on the back to help him with his coughing. Finally, Spike hacks out a small magical orb. It bounces on the floor, out of the prison cell, and floats upwards towards Twilight's cage. Twilight peers inside the orb and finds Princess Celestia and all the other princesses inside it in the Prison Lands of Utter Nothingness.
"Princess Celestia!" said Twilight "I'm sorry... I think this is my fault. My friends were looking for some information on the meaning of our friendship and while we were, we accidentally summoned "the Scoundrel" demon."
"It's nobody's fault, Twilight." said Princess Celestia "After Fassbender left Equestria as a pony a long time ago, and when I suspected that he was a demon in disguise, I put a spell on his island to make sure no other demon would escape. But I think Fassbender was being stubborn so he came up with a magic trick that was very dark of him."
"What kind of a magic trick?" asked Twilight
"He made a drawing of himself but didn't make it come out too good." explained Princess Celestia "He put a curse on it that whoever found the drawing would be able to summon him from his fog prison. He made the drawing disappear and sent it someplace where you, Twilight would might be able to find it. But I never thought it would end up in a file section in your castle."
"Princess Celestia, why didn't you tell me my ex was a demon for this whole time?" asked Twilight
"I thought it would shock you too much." explained Princess Celestia "Besides, by the time I found out, you had already moved on and thought you wouldn't care."
"Princess Celestia, who's going to save us?" asked Twilight
"I've already thought of somepony but I don't want to say who it is." said Princess Celestia
"No," cried Twilight. "Don't tell me. Please, don't make him do it, don't pick him!"
"I have to, Twilight. He's the only one who can save us. I have to go now."
"I understand." said Twilight sadly.
The magical orb disappears in front of Twilight.
At the Prison Lands, Princess Celestia begins making preparations for her plan.
"Princess Cadence, are you sure he's gone through all the training that Shining Armor gave him and that he will be able to defeat a demon such as 'the Scoundrel'?" asked Princess Celestia
"I have to say yes!" said Princess Cadence "He's our only chance."
"Sister Luna," Went on Princess Celestia. "Will you be able to send that kind of important message to him through a dream?"
"I've never done day-dreams before but I'll try as hard as I can." promised Princess Luna
Princess Luna raised her horn in the air as she got ready to send the valuable message to Flash Sentry while Princess Celestia and Cadence stepped back.
