PROLOGUE

It was a fine day in United Equestria, sometime before the war of King Sombra, and the tragic death of Twilight Sparkle. For now, she was alive, and enjoying a day off of her Starfleet Duties with Spike, and their friends Krysta the fairy, and their commanding officer, Admiral Lightning Dawn.

They were playing a fun game, called "Magic Card Creatures" It was a game invented on Equestria of old, several years ago. Enchanted cards with paintings of unusual creatures on them; the cards were placed on what resembled a chessboard, and then the creatures on the cards would magically come to life, as tiny magical illusions. The object of the game was to call forth monsters, battle out with your opponent and attempt to diminish the opposing army.

There were also other types of cards besides monsters: items, weapons, spells, traps, and various other things that could work with or be used against monsters or manipulate the playing field in any way.

Twilight has just dominated most of Lightning's forces with a single monster "The Mutated Ogre of the Swamp…" Twilight said "He washes all soldiers on the ground with his sludge spew."

Surely enough, her monster did just that- spewed out a whole wave of goo from his huge mouth, and most of Lightning's ground forces were wiped out in the surge.

"Okay… that's a wee bit gross." groaned Spike "Cool… but gross."

Twilight felt confident that her victory was assured. "She's got us now, Lightning." said Krysta "I don't see any way out of this one."

"Oh, but there is…" Lightning said with a cheeky smirk on his face, and he placed a simple card on the field "…The Swarm of Sporelings."

Twilight gasped in shock, but Spike was confused "How can they beat a huge ogre like that?" he asked "While he could just swat them all and…"

"Actually…" Lightning cut in "…The Sporelings carry with them an endless supply of burning pollen, which the Ogre of the Swamp is deathly allergic to."

Twilight's monster indeed acted deathly ill to Lightning's insects, and the reaction was so deathly, the monster just disintegrated in a burning flare. "Ah!" cried Twilight.

"And that takes your life-force to zero." Lightning gloated.

Twilight sighed irritably "…Yes it does."

"Yay!" cried Krysta. Twilight and Spike gave her a look. "Sorry, can't help it."

Lightning added up the total sum on paper. "I make it… seven-hundred gold pieces you owe me."

Twilight cheekily rolled her eyes. "It is just one paper, you know."

Lightning chuckled. "Still, this is a great game. We never had anything like this on Unicornicopia."

"Well, it's only several years old." said Twilight "Besides, it was inspired by something…" she stopped.

"Something…?" asked Lightning "Something what…?"

Twilight began to seem strange, and was stammering, and Spike was nervously shaking his head at her telling her "No, don't."

"What's going on?" asked Krysta.

"If there's something vital you two aren't telling us, you should probably say it anyway." added Lightning "Look, I'm not making this an order, but tell us what it is."

Twilight and Spike knew it would help clear the air a bit, and it would help if their friends knew. Twilight fluttered her wings, heading up to her bedroom, and she came down with a very small locked box, sealed with one of her spells. She uncast the magic, and opened the safe, and dumped out a whole bunch of badly conditioned, but very visible cards from another game.

Lightning and Krysta examined the cards, and couldn't figure out much of them, except the inscription on the cards, and the country they were printed and distributed in. "These come from Earth." Lightning said "…The human world, in the alternate universe." added Krysta.

Twilight informed her friends that her friends, Cadance and Shining Armor, even Princess Luna and Celestia- they had cards as well that came from the human world. "We all just woke up one day, and these cards were just here…"

Lightning blinked once. Cards from the human world didn't just appear so suddenly without notice or reason. "What happened…?"

"We didn't remember…" Spike said. "Like we said, we just woke up one day. We didn't remember anything."

Twilight nodded "But… we did see…" she explained how her curiosity of the cards led her to ask Zecora one day, but Zecora was just as baffled herself as what happened. Luckily, they were able to contact the spirits, and they were shown exactly what happened… every single step.

"I think I can recreate the images…" Twilight said, and she quickly retreated to her lab, and conjured up a special potion in a cauldron.

"Sounds like we're about to see a show." said Krysta, and she made herself comfortable with a small bag of popcorn by her side. The others looked at her awkwardly. "What…?"

"Ready…?" Twilight asked. The others nodded, and she then zapped the potion with a magic beam from her horn, and instantly, the magical images began to appear.

…

It was a simple time in Equestria of old, before Starfleet came and United Equestria was formed. Twilight was still just a normal Unicorn, and not princess yet. It was just a simple day, a very beautiful day. The one year anniversary of the marriage of Princess Cadance and Shining Armor, and the mane six, and Spike were all personally invited out to a lovely picnic celebration, organized by Princess Celestia and Luna.

It was a wonderful time…

Twilight played a lot with her brother, wand with her sister-in-law, re-enacting old fun times, and memories.

Pinkie Pie was being a little crazy, even snatching Celestia's cupcakes before she could eat them...

…which Celestia took in humor.

"Oh, really Pinkie Pie, of all the imprudence." groaned Rarity, but then she looked down to notice her own cupcake was gone- Pinkie had just snatched it as well. "Ah!"

"Um… you can have mine if you want, Rarity." said Spike as he shyly held out his sapphire cupcake to her. Rarity of course didn't eat gems, but she thanks Spike nicely, and gave it a small lick with her tongue "Uh… eh… very… unique."

Fluttershy and Applejack were relaxing on the soft cool grass. "Ah… yes ma'am, this is the life." said Applejack. Fluttershy felt too comfortable and relaxed to say anything.

Suddenly, Rainbow Dash wooshed right past them… making them both jump, thought Fluttershy was panting heavily and her heart was pounding in fright.

"Yeah, a new record…!" Rainbow hollered.

"Dag nabit, can't a girl enjoy some relaxation without getting near missed." groaned Applejack.

Fluttershy could only slowly sag down again, still shivering.

"Fine, be that way…" Rainbow muttered, and she continued to fly about.

While Twilight was still having loads of fun with her family, both she and the others were playing sneaky tag, hiding around the trees and shrubs, and then jumping out and surprising one another. Cadance and Twilight jumped on Shining Armor and began to tickle him to no mercy. "No… No…!" he laughed and squeaked.

"Did you hear that, Twilight?"

"Yeah, he said he wants more."

"Aaaaah…!" cried Shining Armor as he continued giggle and laugh at the mercy of his wife and sister.

Meanwhile, the two royal sisters were in the flower fields, picking flowers for the palace dining room table. It was an old favorite pastime of theirs when they were both fillies. Sadly, it reminded Celestia of how much she missed her fiancé, Celesto, whom she hadn't seen in a-thousand years since Luna, as Nightmare Moon cast him out into Dimensional Space, where he was teleported away to unknown regions.

Though it filled them both with high levels of grief, and Luna with shame for what she had done. They knew they couldn't let their problems ruin this special day.

Suddenly, a bright light flashed in the sky. Everyone looked up. "What is that?" asked Twilight.

"I don't know…" asked Celestia.

Before anyone could make any guess, the bright flash emitted a large glow that shot at Celestia. "Sister!" cried Luna. Celestia lay flat on the ground, and then suddenly, her eyes snapped opened, and she bolted upright fiercely. "Princess?" cried Twilight "Are you alright…?" added Cadance.

Celestia smirked, rather sinisterly. "I feel very fine…" and with that, her eyes gave a bright glow of light that seemed to envelope everyone, and spread all across the planet.
