"Now" Empress Luna "In you world, you are ruled by Princesses, myself and Celestia. Correct?" The Elements nodded. "In this world of yours, "Mud or Earth Ponies, Griffons, and Minotaurs have rights?" Luna said, staring at the 6 Elements. "You mean they don't here?" Rainbow asked, staring both the Pinkie Pies and Applejacks.
"Many Mud ponies, or Earth Ponies as you may know them, alongside the savage Griffons and the muttonheaded Minotaurs have become what they always should have, slaves." All of the Prime Elements gasped, as slavery had been outlawed centuries ago. "Oh right, diffent worlds an all, no matter." Empress Luna said.

"Well, actually" Twilight began "EMPRESS Luna, if Nightmare Moon was destroyed, then how are you here? Weren't you two, you know, the same pony?" Empress Luna shook her head. "Not quite Twilight, yes. we did share the same body, Nightmare was a seperate entity from myself." Empress Luna said, trimming her hoof with a hoof-file. "Ah, thank you." Twilight said. "Now, we have to find out why and how you got here." Empress Celestia said, having closed the last book on trans-dimensional travel. "Well, I was practicing on a travel spell, able to teleport a pony farther than normal teleportation, thought I guess I should'nt have done it inside the TARDIS." Twilight said, a faint blush coming to her cheeks, alongside a sheepish smile. "OR, It could be because the Lord Author, the one who created this fanfic, made it so!" Pinkie Pie and Pinkamina stated, each high-hoofing the other not soon afterward. "Anyhoof, I guess we could see what the....urm, Equestria of this dimension is like! We could never get an oppertunity like this again!" Twilight Sparkle said, picking up a quill and notepad, Lady Sparkle following suit, saying "And I can't wait to learn about yours!" The double-duo said. Everpony in the room facehoofed.
"Well, we better get going. And that WASNT a statement, it was an order." Empress Celestia said. "Come along, Lady Sparkle." she said, turning to Sparkle. "Yes, mistress."
They took off in a zepplin, to see the Mirror Ponyville.]
