The Backup Plan
"Your spell! Perform your spell!"
As soon as Shining Armor and Cadence were together, Chrysalis knew it was that she was finished.
She kept up her "arrogant, evil invading queen" façade, but she knew the current invasion was doomed. The force field Shining Armor could create could force out all her changelings from the city, and there was practically nothing she could do about it. At least she had enjoyed the last bars of her song.
"What good would that do? My changelings already roam free!"
Misdirection- a changeling's forte. Breaking her opponents' resolve would be her only chance at stopping the force field from forcibly removing all her changelings from the city. But there was a very small chance of that happening- from what she had learned of Shining Armor during her stay at the castle, he was determined to succeed, no matter the odds. So she needed to form a backup plan. What could she do...?
"My power is useless now! I don't have the strength to repel them..."
"My love will give you strength."
Ah. She had it.
Chrysalis strode over to the window. "Ah ha ha! What a lovely, but absolutely ridiculous sentiment." After she finished the sentence, she bent over, running over her plan and preparing her illusion.
As the two lovers rose up into the air, Chrysalis charged her horn, focusing on the glow not being visible. She opened her mouth to gasp, in mock shock. She already knew what would happen- the power of love would overcome the villain. Or at least, that's what everyone else in attendance thought...
As the force field began to expand, Chrysalis made herself invisible, and left an illusory copy of herself in her place. "No! "NOOOOOOOO!" the illusory Chrysalis shouted, flying out the window as the forcefield hit her. The real Chrysalis, on the other hand, enjoyed a light tickling sensation, the power she had absorbed from Shining Armor and Celestia overcoming that of the force field. She felt a twinge of regret when she saw her changelings fly out of the city, but quickly dismissed it. They would have their chance again, later. For now, she had work to do.
Chrysalis sneaked out through the open door as the lovers descended to the floor. As soon as she was out of earshot from the room where the Bearers, Shining Armor and Cadence were, she began to gallop to Princess Luna's room...
Chrysalis opened the door to Luna's room. She didn't want to wake Luna prematurely, or she would have an angry moon goddess on her hands. For now, though, she was just snoozing, having somehow slept through the commotion of the invasion.
Chrysalis crept to Luna's bedside and muttered a spell. The beam of magic hit Luna in the face, ensuring that she would be sleeping for many months to come. Chrysalis looked Luna over, nodded a few times in preparation, and disguised herself.
"Oh, sister, I missed thou sooo much!" she mocked, in a perfect imitation of Luna's voice, before letting out a cackle. She then unceremoniously teleported Luna to a cave, in a mountain several miles from Canterlot. She would not be foolish enough to teleport another victim to the same place as Luna- after all, the same mistake she had made with Twilight might happen again.
Now she had to wait for a while- Luna was nocturnal, and she still had a while to wait before going down to check if there was any suspicion that she had escaped. After all, she couldn't risk having a future invasion be ruined due to her own incompetence.
"Hello, everypony. Did I miss anything?" "Luna" asked the bearers and Celestia. They simply smiled awkwardly in response, not quite knowing what to say to her, before breaking out into a ridiculous song about how "love was in bloom." At least there was no suspicion here, which was good. Chrysalis broke out in a grin. She had a lot of planning to do for the next invasion...
Changelings streamed into the city, in tight formations. Ponies ran around in absolute hysteria as the chittering horde descended upon them, ready to feast upon their love. "RUN FOR YOUR LIVES!" a blue pony with lighter blue streaks in her mane screamed in panic, as ten changelings descended upon the sound, quickly gluing the pony in place with their... secretions.
A small group of changelings was not in Canterlot, but instead in Ponyville, dealing with the Bearers and the newly ascended Princess Sparkle.
"HAY! Let us go, ya varmint!" Applejack hollered, straining with all her considerable might against the glue-like substance that bound her. "Yeah! If you don't, Princess Celestia will blast you into Changeling dust!" Rainbow Dash yelled. "Ssso ssssory, but Princesssss Celessstia won't be ssssaving you. Sssshe hassss her own presssing problemssss at the moment. Sssssssscared yet? And yessss, I am usssing "ssssss" wordsssss on purposssse." A changeling taunted. This only made them all strain harder against their constraints, to no avail.
Back in Canterlot (ssssssssssss)...
"Shining Armor! Guard Platoon Solar Seven! Subdue them!" Princess Celestia commanded, looking nervously at the sixty changelings that had just buzzed into the room. But as long as her sister was by her side, she was sure that the changelings would be defeated again- especially since there was no sign of their queen. Perhaps she had... died?
"Oh, I don't think they'll be needing to do that, Princess..."
Speak of Discord...
"Chrysalis," growled Celestia. "Where are you?"
"Oh, I'm right here. Can you not see me?"
Celestia whipped her head around, looking for any trace of her, but could find none. There was only...
"Luna," she whispered, as it finally dawned on her.
"Finally. Thank you."
The last thing she saw was her "sister's" grinning face. Then everything went black.
