Annulment

Princess Cadance and Shining Armor stood happily at the alter as Princess Celestia performed the wedding vows that would unite the two lovers for the rest of their lives. Oh how long each of them had waited for this wonderful day to be upon them and with a few more words, Cadance and Shining Armor would be husband and wife!

Princess Celestia smiled fondly at the two lovers in front of her. She had been looking forward to this day almost as long as the two of them had and now that it was here, she couldn't be happier. Her niece was marrying her most trusted guard and she knew that it was a match made from perfection and it was one that she foresaw bringing a lot of happiness to each of them. She opened her mouth to say the fateful words that would unite the two forever.

"I now pronounce you Mare and Colt," she said. "You may now kiss the bride."

Shining Armor walked forward and gave Cadance a quick peck on the lips. Celestia frowned a bit. It didn't seem like a very passionate first kiss for a new husband and wife but...no; it didn't make total sense for her.

The crowd of ponies cheered and behind them all, a Sonic Rainboom exploded from outside. Rainbow Dash had done her job well and it perfectly completed the image of the happy couple. Things were going pretty...

"STOP!" said a loud voice at the end of the room, close to the door.

The crowd looked on to see a very angry looking Twilight Sparkle walking into the room.

"You can't do this!" she said. "You can't marry this imposter!" The crowd gasped. Imposter? What was Twilight talking about? This was Princess Cadance, there was no way that she was an imposter. Twilight's friends looked around uncomfortably and Princess Celestia gave Twilight a sad look. She should have just stayed in her room until the wedding was over; this wasn't the best place for her to be right now.

Princess Cadance gave Twilight a smug smile.

"You're too late Twilight," she said in an unsettlingly happy way. "Aunty Tia already pronounced us mare and colt. Shining Armor is officially my husband now which means that you didn't ruin my special day!"

"It's not your special day, it's mine!" said another familiar voice. The crowd gasped once more as a disheveled Princess Cadance walked into the room behind Twilight Sparkle.

"Two Cadances?" said Applejack confusedly. "How can there be two of 'em?"

"She's a Changeling!" said Cadance, pointing an accusatory hoof at the other Cadance. "She takes the form of somepony you love and feeds off their love for you!"

The crowd was silent for a moment before Cadance two began laughing evilly. Suddenly, her body began to glow and it was almost as if her skin began to melt away, revealing a black sort of exoskeleton underneath. Cadance two continued to laugh evilly as the exoskeleton spread all over her body. Her wings turned from feathery ones to insectoid wings and her mane turned into a sort of teal color.

With one last flash, Cadance two completely finished transforming and she stood in front of the entire crowd of ponies. They all gasped at how hideous this new creature looked.

"Right you are, Princess. And as queen of the Changelings, it is my job to find food for my subjects! Equestria has more love than--"

Suddenly, a large crashing noise filled the room and the sounds of hundreds of hooves and wings echoed throughout the hall. Anypony who wondered what the heck was going on soon got their answer as hundreds of Lunar Stallions filled the room, charging directly towards the Queen. The Queen gave a yelp of shock and flew up into the air, hoping to escape the mob of Lunar Guards but before she could, a dark blue glow enveloped her and she was frozen to the spot.

Everypony in the room backed away from the alter as a very angry Princess Luna walked into the hall. Her anger combined with her generally intimidating presence made everypony do their best to stay out of her way. Even Princess Celestia looked a tad unnerved.

Luna walked up to the Queen and stared deep into her green eyes as if trying to gouge them out by the sheer force of her anger.

"Chrissy, what in the name of my sister are you doing here!?" asked Luna angrily. The hall became so silent that anypony could hear a pin drop. To Twilight's surprise, the Queen smiled at Luna.

"Oh, just staging my most recent invasion Lulu. What are you doing here?" she said.

"Okay, first off, don't call me 'Lulu' I prefer going by my actual name. Secondly, I live here and I showed up to come to my niece's wedding!" said Luna. The Queen's smile widened.

"Yes about that, your sister pronounced me and Shining Armor here as Mare and Colt already. Him and I are very much husband and wife now and there's nothing you can do about it!" she said smugly. Luna's mouth dropped open in shock and she turned to Celestia.

"TIA!" she said. "What the Tartarus!?" Celestia quickly recovered from the shock of the reveal of the Queen as well as Luna's arrival.

"Well she was disguised as Cadie at the time! How in Equestria was I supposed to know that she was actually Chrissy in disguise?"

"Because I told you that she was evil!" said Twilight. Celestia rolled her eyes.

"Okay, besides that. What were the odds that she was actually Crissy?"

"Has she been acting like Cadie lately?" said an irate Luna. Celestia looked down uncomfortably.

"Well...no. According to Twilight, she's been downright unpleasant lately," said Celestia. Luna sighed and facehooved Celestia. She then turned to the Queen.

"I assume he's brainwashed?" she said, pointing at Shining Armor. The Queen laughed.

"You know me too well," she said happily. "Ever since I gained control of him, his protection spell has become weaker and weaker! Even now my minions are chipping away at it!"

"You mean the minions that three battalions of my Lunar Army just drove off?" asked Luna smugly. At this, both Celestia and the Queen's mouths dropped open in shock.

"They drove my babies off?" said the Queen in horror.

"You still have your Lunar Army!?" said Celestia in shock.

"How could you do that to my precious children?"

"I thought that they disbanded when I banished you to the moon!"

"If you hurt one little inch of their precious forms them, I'll destroy you all!"

"Why didn't you bother to inform me of this?"

"Can somepony please explain what is going on?" asked Twilight but she was ignored.

"You didn't hurt them, right? You wouldn't dare!"

"How am I supposed to trust you if you can't trust me enough to tell me that the Lunar Army has formed once more!?"

"SHUT UP!" said Luna angrily. Celestia and the Queen stopped talking and stared at Luna in shock. Luna took a deep breath. "Now, I didn't hurt your children, I just scared them off." The Queen breathed a sigh of relief and seemed to go back to her relaxed demeanor. "As for why I didn't tell you about the Lunar Army, we shall discuss that later! Right now, we have a prisoner to take care of," said Luna. The Queen smiled once more.

"I suppose it was my turn anyway," she said.

"That and we have a wedding to annul!" said Luna. Celestia sighed and rubbed her temple.

"Very well," she said. "You are right; this is not the time or place to deal with these matters. Guards! Take Chri...I mean, Queen Chrysalis away and put her in the high-security cell. Do not let her escape!"

"Why would I escape now?" asked Chrysalis mockingly. "I wouldn't dare leave without my new husband!" Luna and Celestia gave grunts of anger and they both followed the guards who led Chrysalis away.

The hall was silent once more. Shining Armor still stood at the alter, a blank look on his face. Cadance and Twilight looked at him confusedly as did the rest of the ponies.

At that moment, Princess Luna burst back into the room and fired a beam of magic that hit Shining Armor directly in the head before promptly leaving the room once more. Shining Armor fell the the ground and Cadance rushed over to him worriedly.

"Are you okay!?" she asked worriedly as she helped him to his hooves.

"Uh...I think so. Is the wedding over? Are we married now?" asked the disoriented unicorn. Cadance's eyes filled with tears and she hugged her would-be husband and cried into his shoulder. Shining Armor looked around confusedly. Everypony in the room had a look of shock and confusion on their faces, something that worried him very much. "Can somepony please explain to me why my wife is crying like this?" he asked. The term only made Cadance cry even harder.

Twilight stared at the couple, her mind still reeling from what she had seen only a few minutes ago. She felt that she needed to say something, but she wasn't quite sure what to say. What does one say when their brother is tricked into marrying an evil insect queen who was only using him to basically eat love? She opened her mouth and said the first thing that came into her mind.

"What just happened?"
