Four Empeors in Equestria

"A pink horse? Did not expect this." Said Ferdinand, "Can we ride it?"

"Um, I have a name, and it's Pinkie Pie!" She starts giggling and bouncing up and down. The Emperors' eyes all widened, as they noticed other ponies, speaking perfectly.

"What the hell? Oh mein gott! The ponies here talk?" Said Wilhelm. "It's hard to admit, as a mighty Kaiser, but honestly...it's kinda adorable. Strange, yes, but adorable, she's pretty fluffy." Wilhelm starts petting her.

"Of course we talk silly! You're those weird human things Twilight hung out with once, but...you came from that way? wait, the year of when Twilight did it was 2013...what year is it for you?"

"Why, 1915!" Said Franz Joseph.

"Hmm...might ask Twilight about that, but for now, I wanna get to know you! introduce yourselves!" Said Pinkie

"Why, it would be an honor! I am Kaiser Wilhelm II, Emperor of Germany and it's colonial Empire for 27 years, Leader of the Central Powers! Cousin of George V and Nicholas II of England and Russia respectfully." Explained Wilhelm II.

"I am Kaiser Franz Joseph I, Emperor of Austria for 67 years, also King of Hungary, Slovenia, Bohemia, and Croatia. Greatest ally of the German Empire, we speak the same language." explained Franz Joseph.

"I am Sultan or Caliph Mehmed V, Sultan of the Ottoman Empire and Caliph of the Islamic Faith for 6 years, and devout in said faith." explained Mehmed V

"and I am Tsar Ferdinand I, Tsar of Bulgaria for 7 years. Not as found with the Ottomans, but worth it to defeat the entente powers, who we've been at war with." Explained Ferdinand

"Oh, that's cool, I'm Pinkie Pie, I like cake." She says as she sticks her tongue out. "Anyway, I have to show you to Twilight!" She brings them to Twilight's castle.

"So, let me get this straight, you come from the Mirror world, but not from 2013, but instead from 1915? How?" Said Rainbow Dash.

"Let me explain," Said Twilight, "I've done research, there are mirrors all over Equus, that's our planet's name, and each one goes to a different year. Usually it goes up in years in each mirror, so originally, 2013 was the year of the original portal, but now it is 2023, so in your world, when I was in 2013, you were in 1905. Does that make sense?" explained Twilight, the Kaiser nods his head.

"So, darlings, Pinkie told me about a war between you and nations called England, France, Serbia, Russia, and Belgium, what happened to get you at war with so many nations?" Asked Rarity. Franz Joseph Clenched his fist and his teeth.

"My nephew was shot by a Serbian Black Hand assassin, and Serbia did nothing about it!" He yelled. "Now my nephew is dead and my empire is in chaos! Serbia than called upon Russia and France to help, so I called in Germany and the Ottoman Empire, Bulgaria decided to join in, but Wilhelm decided it was a good idea to invade Belgium, which called in Britain into the war." Explained Franz Joseph.

"Hey now!" Said Wilhelm, "How else could I have gotten into France? The border was fortified all to shit, and we couldn't push through until I invaded Belgium!"

"Calm, calm. Now, Franz, would you consider Serbia the aggressor in this conflict?" Asked Twilight. Franz answered loudly.

"OF COURSE! MY NEPHEW IS GONE BECAUSE OF THEM! THEY DIDN'T DO SHIT ABOUT IT and...and...my nephew...he's gone, and he isn't coming back! Serbia must be taught a damn lesson!" Yelled Franz Joseph, tears went down the Kaiser's cheek.

"The Entente has an advantage on getting on the good side of other nations, I believe Japan is involved as well, which isn't anywhere close to us!" Said Mehmed V.

"They've got a point, Twilight." Said Rainbow Dash, "Maybe we should help them in this conflict? Sure, it might change the flow of history, but...still."

"We must get to Zecora, we must know what would happen if you lose this conflict." Said Twilight, "We must know what is at stake in Earth." Twilight brings them.

"If it is an answer you seek, than do not be weak. Look into the Crystal Ball and see. See what will be...if they lose, what the Earth would chose." The Emperors and Mane Six look into the Crystal Ball, they see what happens in the Twenties, the Great Depression, the Thirties and Forties, the Second Great war, seeing terrorists in the 21st century, and tensions of nukes. They see many atrocities. Zecora is shocked.

"I...I have no words." Zecora walked back. Fluttershy is crying because of the atrocities.

"You...must win this war. I'll talk with our Ruler, Princess Celestia, at once! I must talk to her about an alliance! How can human beings be so cruel...?" Asked Twilight.

"Well, looking around your world..." Said Wilhelm, "It seems your world is peaceful. Hardly any conflict, the magic of friendship, I've heard you say that a couple of times...we don't have that on Earth." Said Wilhelm.

"And three of my generals are ethnically cleansing my Empire. I can't do anything about it, that is not what God wants, nor the prophet Muhammad, Peace Be Upon Him." Said Mehmed V.

"Than it's settled." Said Twilight. "Oh, by the way, war does exist here."

"But do you kill people for being minorities?" Asked Mehmed, "That's what my generals have unfortunately done..."

"No..." said Twilight.

"Than war over here is simply conflict, on Earth, many terrible things have happened during wartime." Said Ferdinand. Twilight flies over to Canterlot, as the Central Powers' Monarchs use a carriage. Mehmed V is praying, as they enter the palace. Twilight explains the alliance to her and why it should happen.

"So, if these humans win a war, than many genocides, terrorist attacks, and pollution will end?" Asked Celestia

"Ja." Said Wilhelm, "What do you say, Celestia, allies?" He holds out his hand, Celestia holds out her hoof as Wilhelm holds it.

"Allies." Said Celestia, "I declare Equestria a member of the Central Powers." The Central Powers, including Equestria, have their flags outside Canterlot palace.
