Sitting on her throne in Canterlot, thinking of the best way to kill Sombra, Nightmare Moon sensed something she hadn't felt in a thousand years. The feeling of the six Elements of Harmony being together.
"Ah." she said "Good. I knew Rainbow Dash would not let me down. Now she just needs to bring them back."
"Who would need to bring what back, my beautiful night?" Sombra's voice asked from the door.
Staring at him Nightmare Moon flared up her horn. Then aiming carefully, shot out a beam of light just missing Sombra over the top of his head.
"Now what was that for my demon?" Sombra said smiling.
"YOU'RE THE DEMON SOMBRA!" Nightmare Moon shrieked in the Voice shooting another beam at her husband. "WHY DO YOU WANT ME GONE?"
Here Sombra started shooting beams of dark magic towards Nightmare Moon. "Because you're weak!" he said bearing his fangs, "Even with the forces of darkness, you'll always be a second rate Princess!" One last shot and a cry later, and there was a new statue for all to see who came in to the throne room.
Deep in the Everfree Forest, five mares, one bat-pony (unaware her Queen had just been turned to stone), five foals, and a pack of Timber Wolves, were talking about the Elements of Harmony.
Twilight, remembering that the spell she was trying to concentrate on when this all started was a 'Talk to Animals' spell, cast it on every-pony so they didn't need to keep asking Fluttershy to translate.
Then Lupin came up, looked around the group, and recognized Rainbow Dash. Hearing what the purple one had done, he spoke straight to her. "Nice to see you again Rainbow Dash, I'm still not sure how I liked you scaring me and my brothers all those years ago."
Laughing nervously rubbing the back of her neck, not shocked that she could suddenly understand him, Rainbow said. "Yeah. Sorry about that," she said bowing as a sign of respect.
Twitching his tail Lupin then turned to the Cutie-Mark-Crusaders. "I thought our deal for letting Daughter Fluttershy bring you here was that you didn't tell any-wolf where our home is, young ones."
"Mr. Lupin," Applejack stepped forward also bowing, "They didn't tell me anything about your home except of how Fluttershy told them her story, and how you got to talking about the Elements. I asked them to bring me back out so I can ask you if you know how to work them. They may be our only chance to get everything back to how it was."
Turning his eyes to the pony in the stetson, Lupin looked over the ponies all around him, seeing a flare of an Element in each of the mares. Then barking at his pack to do the same, he bowed to the six of them, "It is very much alright, Element of Honesty."
"Huh?" the ponies asked.
"Erm... Father, what are you talking about?" Fluttershy asked surrounded by bouncing cubs happy to be with her and her kindness.
"I am saying Daughter Fluttershy," Lupin said getting up "That you and these other grown ponies, are the new bearers of the Elements of Harmony."
"Wait just a minute," Pinkie called out, she rushed out of view for a few seconds returning with a glass of water, only to drink and spit it out again. "Your saying the Elements of Harmony are real?" she asked.
"Yes Element of Laughter," Lupin said over the yips coming from the cubs. "It seems Discord didn't tell you they really exist."
"Nopey-Lopie, he only told me who every-pony is."
"Then would you like to finish off the introductions?"
"Ok." she cried jumping forward. Then pointing a hoof at the others in turn she said...
"Rainbow Dash is the Element of Loyalty, she was loyal to Fluttershy by staying in Canterlot so no meanie knew where Fluttershy was. Fluttershy is the Element of Kindness, being kind to all animals and your cubs - as well as you and your brothers way back then. Applejack, using her Honesty to run the Resistance against the Three Rulers. Rarity is the Element of Generosity, giving the foals at Sombra's crystal mines the best life they can have at a place like that. And finally Twilight Sparkle, the Element of Magic."
She finished very much out of breath and phlumped on the floor. All around her, the ponies were staring at her, then to each other, then to her again.
"Well done, Pinkie," Lupin said bowing to her. Then turning to Twilight said, "But I assume you already know all this Twilight."
"Er..." Twilight said not knowing what to say.
"We wolves have far better senses than ponies. We knew Princess Luna was standing behind that tree the whole time."
Then out of the darkness, stepped Luna, and by the reactions of very pony other than Jewel and Saturn, let herself be seen by everyone.
"Indeed she does good Lupin," she said bowing to the pack leader. "She's from another world where her dissensions led to a better life for every-pony..."
"Wow...Wow...Wow," Rainbow said "Back up." then turning to Twilight said, "If everything in that world was so much better, why did you wish to come here."
"I didn't do it on purpose ok," Twilight said tears forming "All I said was 'I wish I never came to Ponyville.' I didn't know what would happen." Then after a little thought said, "Besides, it's Luna's magic creating this place."
"Granny-Smith always said 'be careful what you wish for,' there Sugercube," Applejack said, going over to comfort Twilight.
"What do you mean Luna's magic is doing this?" Rarity asked looking Luna up and down.
"There's no time for to answer that." Lupin said getting up. "You need to get to the Castle and get those Elements.
"Right." they all said, running out into the forest.
Lupin held back Twilight - Luna had gone to show everyone where the castle was.
"You may be worried. But I promise you this will work," he said "After you use the Elements on the Rulers, everything will go back to normal, for this world and for you too," he said walking her to the edge of the Wolves home.
"Thank you Lupin," Twilight said bowing, tears in her eyes. Then ran after her friends.
