Happy Hearths warming, Sunset

"WH-what!? No! We can't meet with the changelings!" Cried Twilight frantically. "They tried to take over Equestria!"

"Well, all we know is that they tried to invade Canterlot, not all of Equestria" explained Sunset quickly. Twilight glared at her sternly. "Well, I already told them that we'd meet. In two days" she added. Twilight snapped back to glare.

"You what?" She hissed.

"We can't just have the changeling princess following us around. What if we get so weak, that we can't do our part in defending Equestria!?" Rushed Sunset. Twilight opened her mouth to speak, but closed it and clenched her jaw.

"Fine" she whispered. "Fine. J-just, I need a shower" she turned and trotted into the bathroom, shutting the door behind her.

"Ugh" sighed Sunset, sitting hard on the tiled kitchen floor. "I should go apologize" sunset walked down the hall to the bathroom, but stopped short. She saw a large pile of purple feathers. Twilight’s feathers. A little ways down the hall was Twilights crown. Finally, just outside the bathroom was a large pile of her hair. Sunset opened the door carefully, expecting to find a perfectly reasonable explanation. Instead, she found a changeling. The two stared at each other for a long time, and then Sunset screamed.

                                                                    ***

"Who are you?" Hissed Sunset to the tied up changeling. She didn't say anything. "Who are you!?" She roared, causing the changeling to flinch.

"M-my name is Locusta" she squeaked, flapping her transparent wings lazily.

"Where is Princess Twilight?" Pushed Sunset, eyes narrowed.

"Sh-she's in the... the" started Locusta, but started crying.

"Where!?" Boomed Sunset again.

"The Ever free!" She cried. Before she could go on, Sunset was out the window, soaring to the Ever free. She went as quickly as she could, skimming trees. She kept going until she felt a tug in her horn. Alicorn magic. She instantly dived, running to the source until she came across a large, silver cage. Sitting inside was none other than Twilight, a magic blocker on her horn. She was growling furiously and bucking the bars as hard as she could.

"Twilight!" Cried Sunset, reaching through the bars. Twilight turned quickly and gasped.

"Sunset!" She cried, running forward. The two kissed through the bars before Sunset kicked the large lock, shattering it. The two embraced tightly. Let's leave these two for now and travel north. A large black chariot was soaring through the skies, containing a dozen changeling guards, along with their queen. The destination, Ponyville.

                                                                  ***

    Twilight and Sunset flew back to the castle together.

"How long were you in there?" Asked Sunset with concern in her voice.

"About four days" replied Twilight, eyes down.

"Well, I missed you without realizing it. I love you, and I'm so sorry I didn't notice sooner" said Sunset.

"It's fine. I just spent so many nights missing you"

"And I you. Oh, we're here" said Sunset, dipping down and landing on the clean, green lawn. Outside was a large black chariot. The changeling queen was stepping out of it with a half dozen guards.

"Q-queen Chrysalis!" Stuttered Sunset, bowing. Chrysalis did the same.

"My apologies. Your young drake informed me that you found my daughter. Please, where is she!?" She asked frantically. Sunset nodded and opened the front doors, running inside. She returned a few minutes later, the changeling princess following in her stead.

"Oh Locusta, my little Princess!" Cried Chrysalis, lunging for her daughter and wrapping her in a tight hug. They both began to glow slightly. "What were you thinking!? Running off and taking a princess' place!? Do you realize how dangerous that was!?" She soon cried.

"I'm sorry mom" whispered Locusta. A few minutes later, the two broke apart. Chrysalis nodded to a guard to take Locusta into the carriage.

"Thank you ever so much" said Chrysalis, bowing and turning back to the chariot.

"Wait!" Cried Twilight, surprising both Sunset and herself. "Please wait. You were banished to the badlands, you and your kingdom. You're starving to death out there. Please, come in and feed the ones you've brought with you" she pleaded. Chrysalis remained silent, but nodded. She gave a short, shrill whistle and summoned her guards. They feasted and laughed as friends. Changeling and pony, sitting around and having fun with each other. They left with enough food to feed all of them for months. So much that they had to magically compact them.

"Thank you" the queen had said. "I would like for our ponies to become one. We would be able to provide great protection for Equestria. More than that, I'd like for us to be friends. Thank you so much for not hurting my little daughter. Thank you for saving us. Thank you for showing us a little friendship. I'm ever in your debt"

A month later, the two kingdoms became one. A year after that, Princess Twilight and Princess Sunset were wed.

Never before had a pair of ponies danced as beautifully as these two on their wedding night. The union of Twilight Sparke and Sunset Shimmer was so beautiful, many strangers cried. The love between them was so true and pure, that changelings for miles around could feel it. They felt stronger. They felt happier. They felt love. Almost a year later, the two were blessed with a foal. It had to be done magically, of course, but it was still their child. A bouncing bubbly daughter. Her coat was black and her hair was dark blue. Shadow Charmer. A young alicorn filly with amazing magic powers. She would, well, as her name tells, she could charm shadows. As a filly, she could only do small things, like warping shadows to make balls to play with. And what happened to the people at Canterlot high, you may ask. Sunset and Twilight both went through just after the wedding. Her friends were so nervous, but so happy to see that she was alive and well. They were certainly surprised to find that she was a princess, had united two species, and was married. The trip ended all too soon, and Twilight and Sunset were back in Equestria. They spent the rest of their lives together, and had many, many adventures. But that is for another story.
