Now, let's start the final chapter.
Twilight darted her eyes back and forth, making sure everything was going right. She wouldn't let anything go wrong in the biggest wedding in decades. She wouldn't let anything spoil the wedding of her mentor. Ponies from all around Equestria had attended, including Cheese Sandwich, and Steve Magnet, who was attending with only his torso stretching inside from one of the hall's windows.
"Howdy there, Twi!" Applejack greeted. "Everything is goin' alright?"
"Yes, everything is fine! Nothing is going wrong. NOTHING must go wrong! Everything must be PERFECT!" Twilight said hysterically.
"Whoa! Calm down, Sugarcube. I'm sure everything will be dandy."
"Hi there, Twilight!" Pinkie jumped in the scene. "Oh, that cake looks sooooo delicious!"
"What? You and Mrs. Cake baked it, and now you realize it's delicious?!" Applejack said.
"Whatever, I can't hold myself!" Pinkie drooled, then took a small bite from the cake's bottom.
"PINKIE!" Twilight used her magic to extract the bite out of Pinkie's mouth, then she placed it back where it was previously, making sure to fix its shape as much as possible. "Out of all the occasions, you chose Celestia's wedding to do this?!"
"But, it was just a small nibble!" Pinkie smiled sheepishly.
"No nibbles at all!" Twilight inhaled and exhaled slowly to calm herself down.
"Don't get so nervous, darling," Rarity said. "I mean, if you are that nervous, then imagine how much Celestia must be?!"
"Rarity is right, Twilight," Spike said.
"I don't know about Celestia, but..." Twilight glanced around her. "Where are Derpy and Roseluck? I'm not going to be the only Bridesmare, am I?!"
"Geez, Twilight! It's not the end of Equestria!" Rainbow Dash said, hovering near Twilight.
"Hey, Rainbow Dash, give me a little bit of your awesomeness!" Sunset said, holding her phone to take a photo of Rainbow Dash.
"You got it!" Rainbow Dash happily made a superhero pose, then Cheese Sandwich jumped high, placing himself in the photo, before Sunset's phone gave a white flash and made a photo taking click.
"Yes! I'm sure Rainbow Dash back in the other world will be excited to see her pony self!" Sunset said, looking at the photo she had just taken. Then, she faced the cake. "Oh, the cake! Of course." She began to snap photos of the cake. "Sorry, Twilight, but I promised the girls that I would make them feel like they attended the wedding for real."
"It's okay, Sunset..."
"Oh, Fluttershy!" Sunset saw Fluttershy trotting side by side with Danny the Changeling, and galloped towards her. "Here, just a photo. The other Fluttershy will blush to death when I show her this!" Sunset stood in front of Fluttershy and Danny, then took a selfie with them.
"Hey! Doesn't the human me want to see his pony self, too?!" Flash Sentry asked.
"Sure he does!" Sunset rushed towards Flash.
Twilight sighed. "I'll go check on Princess Celestia." She turned around and left the hall.
Twilight reached Celestia's dressing room and knocked on the door. "Princess Celestia, it's me, Twilight. I came here to...well, I don't know, I just wanted to talk to you."
"Okay, Twilight, I'm almost done," came Celestia's voice from behind the door.
When Celestia came out of the room, Twilight's eyes opened widely. Celestia was wearing a wonderful white dress with golden embellishment.
Celestia fixed the dress' shoulder and faced Twilight nervously. "Wh...what? Do I look good?"
"Good?! Try 'Astounding'!" Twilight said, gaining a warm smile from Celestia. "I'm sure Sombra will melt once he sees you."
"Oh, thanks, Twilight." Celestia blushed. "So...what did you want to talk about?"
"Honestly, there's nothing specific. I just though that it would be nice to talk to my mentor before the biggest moment in her life. I mean, you literally fought in order to reach this moment."
"Twilight, we all fought to reach this moment. Actually, you gave me this moment. You and your friends made it possible. I'm in your debt forever."
Twilight smiled broadly. "Anything for you, Princess Celestia. You were my mentor and if it weren't for you, I would have never been able to reassemble the mirror."
"What can I say, the student has surpassed the mentor." Celestia patted Twilight on the shoulder. "You didn't only just reassemble the mirror, you also reassembled my heart. Just like the mirror, my heart feels like it has never been broken before, and it's all thanks to you. Now, go and prepare yourself with Derpy and Roseluck."
"Oh, of course! I'll go check them right now." With that, Twilight galloped back to the wedding hall.
In the wedding hall, Twilight found Sunset Shimmer taking photos with Derpy and Roseluck.
"Derpy! Roseluck! Where have you been?!" Twilight asked.
"Oh, we were just hanging around," Roseluck replied, smiling sheepishly.
"We aren't late, are we?" Derpy asked.
"No, not at all. But I was just worried and nervous, that's the whole thing," Twilight replied.
"How is Princess Celestia doing?" Sunset asked, after she had taken a photo of Pinkie and Cheese Sandwich.
"She's better than I expected! You can thank Rarity for the dress," Twilight replied.
"Oh, I sure had to put all my effort to make the wedding dress for our beloved Princess!" Rarity said.
"And your effort showed, Rarity, believe me." Twilight faced Derpy and Roseluck. "Come on, girls, we don't wanna be late. Princess Celestia may arrive at any moment." Twilight, Roseluck and Derpy headed to the stage and stood opposite to Sombra.
A few minutes later, everyone in the hall stopped talking and stood in the shape of two crowds on the sides of the long, red carpet that led to the wedding stage, where the Bridesmares, Luna, and Sombra were standing. Sunset immediately began to to record a video with her phone. Finally, the doors opened, and Apple Bloom, Scootaloo and Sweetie Belle entered with baskets in their mouths, spreading flower petals in their way. Then, Celestia entered right behind, a small group of birds levitating her long dress off the ground.
Shining Armor was crying his eyes out, when Cadance nudged him.
"What?" Shining asked.
"You're Sombra's Bestcolt!" Cadance replied.
Shining widened his eyes and gasped. "Oh! You're right!" He rushed out of the crowd, but tripped and fell on the ground face first. He stood up quickly, smiling sheepishly, than hurried to the wedding stage.
Cadance face hoofed.
Celestia stood on the stage and faced Sombra, Luna standing between them.
Luna cleared her throat before speaking. "Mares and Gentelcolts, we are gathered here today for the union of Princess Celestia and King Sombra. This is no ordinary wedding, Mares and Gentlecolts. This is a victory. A victory for love. These two lovers have fought and suffered in order to stand in front of us today, on this blissful night, and they deserve to finally celebrate their victory with us." Luna faced Sombra. "Sombra, do you take Celestia to be your lawfully wedded wife?"
"I do," Sombra replied, smiling widely.
Luna then faced Celestia. "Celestia, do you take Sombra to be your lawfully wedded husband?"
Celestia stared at Sombra for a moment, a teary smile on her face. "I do."
Luna couldn't stop a wide smile from forming on her face, for she struggled to hold herself from jumping in happiness or crying in joy for her sister. She levitated two golden rings and placed them around Celestia and Sombra's horns, as she said the following words, "Now I pronounce you, Mare and Colt." Luna face Sombra. "Now, you can kiss the bride."
Immediately, Celestia and Sombra locked their lips together. As they did so, everyone began to cheer loudly, and Luna finally jumped high in the air, unable to contain her happiness anymore.
Soon, the dance began. Everyone picked a dancing partner and began to dance.
"Pinkie, can I say something crazy?" Cheese Sandwich asked.
Pinkie stuffed her hoof in his mouth to silence him. "No, you can't. You can do something crazy! Come on!"
"Alright!" Cheese and Pinkie danced energetically, as energetic as Pinkie and Cheese can get.
"Hey, Rainbow Dash, would you like to dance with me?" Soarin asked, stretching his foreleg for Rainbow Dash.
Rainbow Dash widened her eyes. "Yo...You want me to dance with you?!" she asked; Soarin nodded. This is the awesomest day in my life! she thought. "Of course I would!"
"Great!" Soarin took Rainbow's hoof in his and began dancing, but Rainbow was finding a problem keeping up with the dance style.
Rarity saw Blueblood approaching, smiling sheepishly. She frowned and rushed towards Spike. "Oh, Spike? Would you be a dear and dance with me?"
Spike spit the drink he had been drinking. "Wh..wh..what?! I...I..."
"You do? Oh, thank you so much, Spikey-Wikey!" Rarity held Spike in her forelegs and danced in front of Blueblood, showing him how she already had a dancing partner.
Thanks for your...existence, Blueblood! Spike thought.
Rarity danced towards Applejack and stood beside her. "Aren't you going to dance, dear? I know you haven't danced with somepony before, but there's a first time to everything."
"Me? Oh, no, thanks. I'm doin' just..."
"Hey, Applejack! I was wondering if you would dance with me, if you don't already have a dancing partner?" Caramel asked, blushing lightly.
Applejack was taken aback, but didn't blush. "What? Me? Well, I think..." Applejack took a glance to her left, and saw Trenderhoof from afar, waving his foreleg for her. She widened her eyes and immediately decided to answer Caramel. "I say why not, Sugarcube?! I would absolutely dance with ya!"
"Really? That's great! Now..."
"What are we waitin' for?! Let's get dancin'!" Applejack grabbed Caramel by his foreleg and dragged him into a dance.
Rarity giggled. "I hope Caramel can keep up with her."
"Uh, shoot!" Trenderhoof cursed sadly. He then glanced around him and found Sunset taking photos of everything. "Wow! Who's that?! Well, let's try my luck with her!"
As Fluttershy and Danny were dancing, Danny began to glow a light blue, gaining Twilight's attention.
"What's wrong with him, Fluttershy?" Twilight asked.
"Oh, there's nothing wrong, Twilight! This is what happens when a Changeling feels love instead of draining it," Fluttershy answered, smiling with slightly red cheeks.
Danny jumped high in the air, glowing brighter. "I LOVE WEDDINGS!"
Luna slowly approached Big Mac and talked to him shyly. "Umm, greetings, Big Macintosh!" She cleared her throat. "Can I ask you something?
Big Mac raised an eyebrow. "Eeyup."
"Well, would you be my dancing partner?"
Big Mac froze in shock. "E...E..."
Yes! Say it! I know I told you to try other words, but this time, just say it! Luna thought.
"...Eeyup!"
"YAY!" Luna carried Big Mac and flew.
"Hey, AJ! Look what's your brother doing!" Rainbow Dash said, as she and Soarin passed by Applejack and Caramel.
Applejack glanced upwards, staring in shock at her brother and Luna. "Oh, Big Mac! I never knew you were aiming for royalty!" She and Caramel laughed.
As Derpy and Dr. Whooves took two pieces of cake to eat, Dr. Whooves happened to take the piece of cake that had been chewed by Pinkie Pie.
"Hmm, this is..." Dr. Whooves said, after he took a chomp of the cake. "This is great! It tastes like cotton candy! I love it!"
Discord stood alone, scratching his chin, watching everyone having a dancing partner but him. "Hmmm, seems like everypony is busy now. Even Fluttershy and Applejack are busy. Who am I gonna dance with? I mean, I would've danced with Celestia had she not been the bride!" Discord laughed. "Oh, Discord, you laughed at your own joke!"
A mare approached Discord from behind and nudged him gently. "Excuse me, Mister Discord?"
Discord turned to face the mare, widening his eyes in admiration. It was Trixie, wearing a beautiful purple dress, her hair styled in the most beautiful way Discord has ever seen.
"I...I noticed that you don't have anypony to dance with...just like me! Hehe! So...I was wondering, would you..."
"Of course I would dance with you!" Discord carried Trixie by her waist.
"Th...Thanks!"
"Now, get ready for a Discord-styled dance!"
"A Discord wh-whoaaaaaa?!"
Discord twirled Trixie in the air, and when she fell back between his arms, he was wearing a tuxedo and carrying a red rose in his mouth.
"Like it so far?" Discord asked, spitting the rose in Trixie's forelegs.
"I LOVE it!"
"Great! Then we shall move to the next level!" With that, Discord continued with a rather dizzying and stunt-filled dance.
Twilight trotted towards Vinyl Scratch's turntable set and whispered something to her, then picked up a microphone and trotted back towards her friends. The music changed and Twilight began singing her favorite wedding song, 'Love Is In Bloom', and Flash Sentry decided to join her in singing.
Sunset managed to escape Trenderhoof after taking a few photos with him, then moved forward to covering the other things. She recorded a video of Flash and Twilight singing, then a video of them dancing Twilight's awkward dance. And finally, she managed to take a selfie with Rainbow Dash, with Celestia and Sombra kissing in the background.
Celestia stood with a huge group of mares behind her, then threw a bouquet of flowers behind her. The bouquet hit Twilight in the face, and she grabbed it.
"That's not fair! We were prepared to grab it, and she takes it without any effort!" Rarity said, causing all her friends to laugh.
Finally, after the dance was over, Celestia and Sombra headed to the carriage that will take them to their first honeymoon destination. Sombra entered first, then Celestia, but she quickly moved out of it.
"I remembered something," she said. "Twilight!"
Twilight hurried towards her mentor. "What is it, Princess?"
Celestia took Twilight in a tight embrace, crying into her shoulder; Sombra smiled warmly. "Thank you, Twilight! Thank you for everything! For all of this! You gave me what I thought I would never have!"
"Princess, you also gave me what I thought I would never have. You raised me as your student after I was just a nervous filly in a magic test," Twilight replied with a teary smile. "Now, go and start your life."
Celestia let go of Twilight and entered the carriage again, closing the door behind her.
As the carriage departed, Twilight nudged Rainbow Dash. "Do it now, Rainbow Dash!"
"Sure!" Rainbow Dash immediately took to the sky and performed a Sonic Rainboom. "I'm sorry, Cadance, but this is the best wedding ever!"
In the carriage, Celestia and Sombra smiled at the scene of the Sonic Rainboom. Everything was fine. Everyone was happy. There was nothing left, except...
"Sombra?" Celestia face Sombra.
"What?"
"Will you be my mirror?"
Sombra smiled and locked his nose with Celestia's. "Always."
"Always."
-The End-
