Twilight stood in the middle of the library in the Castle of Friendship. Her "apprentice", Starlight Glimmer, was off in the human world, learning about magic from Sunset Shimmer. Sunset had been ecstatic to teach Starlight about the magic in the human world. While the other girls, including the other Twilight, would try to understand Sunset's rants, they didn't really get it. From what Sunset had written, it was a nice change to have someone around who understood at least the basic principles of magic.

Twilight's thoughts turned back to the other Twilight. The girls had decided to call the Twilight from the human world "Sci-Twi" and her, "Princess Twilight"

There's another me, she thought as she so often did whenever Sci-Twi came to mind.

Sighing, she turned her thoughts towards her plan for the day. The girls, CMC, Spike, and herself were going to a Wonderbolts show. It was Twilight's responsibility to transport them to the show.

While Rainbow had wanted to fly up there with the Twinkling Balloon, Twilight's coming of age present from Celestia, cooler minds had prevailed and the group was to be teleported by Twilight.

Even though her ascension had greatly increased her magical capacity, Twilight was still not powerful enough to teleport more than half a dozen ponies, especially as far as Cloudsdale was at the time. So, Twilight was searching her library for a way to transport nine ponies and one dragon. Or ten ponies. Whichever.

Finally, she pulled out a book titled The Transport Guide for Unicorns: How to Transport Six Mares, Three Fillies, and One Adolescent Dragon.

"Well, thats awfully specific," she said.

Twilight flipped skimmed the book until she found the right page. The letters blurred together due to her lack of sleep, but she eventually got the spell written down.

A few hours of sleep later, Twilight met with her friends and the CMC in an open field behind her castle.

"Okay,"she said."Is everypony ready?"

Her question was answered by a chorus of agreement.

Twilight began her spell.

Unfortunately, due to her half-asleep state earlier that morning, Twilight had copied the incorrect spell. This spell was not to transport them halfway across the country of Equestria; this was a spell to take them to whichever world was halfway across the multiverse!

Twilight's spell ended in a great flash of light. Twilight Sparkle, Applejack, Rarity, Rainbow Dash, Fluttershy, Pinkie Pie, Applebloom, Sweetie Belle, Scootaloo, and Spike disappeared, not to be seen again in that world for quite a while.

Meanwhile, in another world...

A small, sleek, skinny, jet-black tomcat with a white dash on his chest, a long, thin, white tipped tail and green eyes, stood beside his mate.

She was bluish-gray with unusual teal eyes. She was giving birth to his kits.

Her sisters, Cadence and Celestia, both near kitting as well, stood nearby, watching. Their mates, Armor and Barley respectively were keeping watch, just in case something happened.

Just then, the cry of a kit sounded. Ravenpaw spun around and bounded toward his mate, Luna. She was licking a miniature, she-kit, version of Ravenpaw himself. Soon, another little she-kit was born. This one was an orange she-kit.

"What should we name them?"Luna asked.

Ravenpaw nosed the little black she kit."How about... Night for this one?"

Luna nodded wearily.

"And Day for this one,"she said, glancing at the orange she-kit.

Far away, but in the same world...

Leafpool and Jayfeather stiffened. A cat from StarClan was walking down the path leading to camp. She turned and faced the medicine cats.

"Not far away,

there be ten lost,

And the Clans are tested,

To send them home."

Leafpool awoke, bristling. Beside her Jayfeather woke as well.

"We have to tell Bramblestar!"he said.

Author's Note

Okay, let me just get this straight. For those of you who haven't read the warriors series, Twolegs are humans.

Also, Ravenpaw is the sleek black tom.

Celestia is a orange she cat with amber eyes.

Cadence is a... tortoiseshell with blue eyes.

Armor is a snow white tom with blue eyes.

Barley is a short, compact, muscular, black-and-white tom with a plump belly and broad shoulders.

Also, in this new world, Cadence and Armor are Night(Twilight)'s Aunt and Uncle. It made sense to me. Keep on reading to find out more.

List of eqivalents:
Night = Twilight Sparkle
Day = Applejack
Rain = Rainbow Dash(Bluish-gray. Daughter of Celestia and Barley. Half a moon younger than Night and Day)
Snow = Rarity(Snow white. Rain's littermate)
Blossom = Fluttershy(Golden tabby. Daughter of Cadence and Armor. Half a moon younger than Rain and Snow.)
Bounce = Pinkie Pie(Tortoiseshell. Blossom's littermate)
Apple = Applebloom(Bluish-gray. Sister of Night and Day by another litter. Three moons younger than Night and Day)
Stripe = Spike(Striped gray tom. Apple's littermate)
Flood = Scootaloo(Orange. Sister of Rain and Snow by another litter. Two and a half moons younger than Rain and Snow)
Blizzard = Sweetie Belle(Snowy. Flood's littermate)

I know there will be people who don't like Sweetie Belle's equivalent, but gimme a break.

I'm trying hard, doing what I can.
Won't you try, just give it a chance?
You might find that you'll start to understand.
