Opening theme is down below here.

Everything has changed since Naturus took over the world. New plants grew on the soil, new animals walked the earth, and nature operated to its own accord. Ponies, buffalo, deer and griffons had to put aside their differences in order to deal with the newer and harsher world that Emperor Naturus rules over. Over the course of a thousand years, new batches of flora and fauna were added from their universes by Naturus to his own universe (mostly because of boredom), forcing the races to prepare every time.

As for Discord, he sat in silence as he watched the world change around him. No one knows what happened to him, but some believed that he went to another universe, knowing Naturus is too strong for him and the fact he is immune to all forms of magic.

Naturus himself ruled former Canterlot as his own when he teleported it a few mile northeast, introducing deer, griffons, yaks, earth ponies, pegasi, minotaurs, cat people, diamond dogs and a few other species to the city as new residents. The alicorns were killed off in front of Canterlot's residents. All except for Mi Amore Cadenza, who has escaped and was aged back to a filly by Naturus when he found and imprisoned her, deciding what he should do with her.

Naturus sent poor Cadence flying forward in time, a few years before Celestia and Luna would return. And he KNEW they would. He knew about the spell. He wanted to make them see what happens. He then hypnotized the world's sentient beings, making them forget all about the alicorns and the incident, making them think it's always been that way. He will do the same to Cadence, making her think she was something special. Naturus is well aware of the one thousand year rule, and waited. In the one thousand year time gap, he has watched the world, and figured out some juicy details.

He noted that the ponies never forgot about the values of friendship, even in a hostile, self-operating world without alicorns. Man, their friendship was stronger than he thought it was. Though, he guessed it was for the best, seeing ponies and griffons forced to team up in that harsher, slightly colder world. Naturus wondered if there was more where that came from. Even with him as ruler, that did not stop them from establishing 'kingdoms' and 'republics' across the world.

During these first 100 years, he managed Natropolis (former Canterlot) and mined the upper half of Mt. Canterhorn to expand the city to accommodate the new residents and relocating the spring Natropolis's center. Second, he converted the old Canterlot Castle into a gatehouse and added walls, complete with guard towers. Third, the guy added two farms and one pasture next to the north and south walls. Finally, at the east wall, he constructed his brand new castle on the east side, and made Natropolis the capitol city of Earth itself.

Now, the clock's ticking. It was almost one thousand years, and he knew it was time.

A lone cyan rainbow-maned pegasus flew over the legendary Natropolis, taking note of how beautiful it was. The walls were made from white brick with rimming of gold at the edges, with blue battlements. Each guard tower was proud and strong, and had purple cones at their centers. The gatehouse was built in a whimsical style, and some even said it was once a castle. It was evident that it was modified due to more battlements and a boxier build. Just behind it was a tall guard base/tower, bigger than any guard building in the sprawling city. Looking into the city itself, she saw housing, a market square, and to the east, Naturus's great citadel, gleaming like a diamond, a beacon of hope and joy for the Natropolians. Truly, this was a community of its own. Close in the walls and you'd still have food and water for a possibly infinitely long time. Prism Strike decided to go into the city itself.

Various flying races are going in and out of the city, so why can't she? And she did. Prism Strike went down to investigate, when she neared the ground, two guards walked to her. Naturus's soldiers did not belong to any known race. They were bipedal beings with four arms and one eye, and they looked like they were made of some kind of iron armor. One carried a spear and another bore a sword.

"State your name." one of the guards said.

"Prism. Prism 'Dash' Strike." the pegasus said.

"Why are you here?" the other guard said.

"I came to look around. Is the market open?" Prism said.

"The market just near here. If you see a water spring and tents, you are golden. Fun fact: The water here is pure and can never be poisoned. If you intend to poison it, well, even though that is stupid, we'll find you." the guard said in a more warning tone. After the guards left, Prism Strike flew aimlessly until she found some tents and a fountain. Had to be the marketplace.

As Prism flew, she took note of all the residents, deer, griffons, yaks and other races were in this melting pot. She looked to her left and saw an animal auction. A guard walked by with an attack raptor covered in red feathers on a leash, some small sauropodomorphs were at an auction pad with a salesman talking about them. A few tents could be made out with rugs, fruit, meat, wine, furniture and clocks in them. People of all species were all around, and she saw a few slaves bound by chains.

It was not long until Prism bumped into a pink mare with a purple, red and yellow mane and cyan eyes. Her cutie mark was a cyan heart with two lines under it. What's even weirder was that she had a HORN and WINGS. BOTH OF THEM! Prism Strike did not even know that was possible, as she studied genetics well enough. A unicorn AND a pegasus, WEIRD! Prism just simply stared at her.

"That reaction is common, but I'm not affended." the pegacorn?-type thing said.

"My name's Cadence. Pleasure to meet you." Cadence said, shaking Prism's hoof.

"The name's Prism. Prism Strike. I'm not trying to affend you, but how are you a unicorn and a pegasus at the same time?" Prism Strike said, causing Cadence to sigh in sadness.

"I have no idea why I'm like that, or what my cutie mark means. In fact, I don't know who my parents are." Cadence said, setting on a sadder tone. Prism Strike noticed it and patted Cadence's back as the pegacorn told her story.

"I don't remember anything until a few years ago, when I woke up in the alleys. All I remember is my name: Mi Amore Cadenza. All else was just a blur, just a hazy fog. I decided to explore the alleyway to try to find out who I really am. And then I wandered into the streets and saw various faces starring at me. Sooner or later, I was accepted, but I never let the city." Cadence said, wiping a tear with her hoof.

"Wow, what a story. Now, if we see each other, I'll bring my friend Swallowtail with me. Bye!" Prism said, leaving a rainbow trail behind her as she zoomed through the skies. Cadence then walked away, knowing she had encounters like this before. She walked through the apartments to find a lavender unicorn that had a navyblue mane with a pink strip in it. Her cutie mark was a magenta star with six points. Six more points were there in white, and five smaller stars surrounded the main one.

"Violet Star, good to see you again. You won't believe the number of flyers there are today." Cadence giggled.

"I don't believe it either, Cadence. And that doesn't count sentient beings. Birds, pterosaurs, giant insects, flying fish and wyverns are flying as well. Come on in." Violet said as she opened the door, letting her alicorn friend in. Violet finished brewing her tea. Cadence pulled out a chair in a teal aura while Violet took hers in a purple aura.

"So, Cadence, how were you today?" Violet Star said as she poured the tea into her cups.

"I've been walking around the city, and it's mostly been usual. At least I have a roof over my head, being a babysitter was my best decision yet." Cadence said as Violet grinned smugly.

"Remember our secret hoofshake?"

"Yes." Cadence said as the two jumped off their chairs and began chanting.

"Ladybug, ladybug, sunshine awake! Clap your hooves and do a little shake!" the two said as they plopped onto the couch, just as a raptor hatchling/chick walked in. More specifically, a Bambiraptor. Unlike most Bambiraptors, this one had purple downy feathers and a green underside, with green wing and tail feathers. The raptor looked at Twilight and was holding a tray of triangular sandwiches.

"Spike, you got the sandwiches, right?" Violet Star said.

"Right, Violet. I have them. Do you want some punch with them?" the raptor, apparently named Spike, said,, holding a pitcher of red punch as the two levitated some sandwiches and took bites out of them while Violet nodded in a 'no' fashion.

"More for me, then." Spike said as he chomped on his sardines, wagging his tail and drinking punch.

"Cadence, remember that time we met in the park?" Violet Star said as she levitated another sandwich.

"Yes. You were so full of questions back then." Cadence laughed as she thought about the memories. Violet Star's parents spotted her and asked Cadence if she wanted to babysit their little girl. Babysitting Twilight was the best decision she made, and she had a new friend that she can have for years to come. In fact, the two had a close bond.

"It's been ten years, can't you belive it?" Cadence said before walking out.

"It's been swell seeing you, bye!" Cadence closed the door, and as she walked, a guard looked at her, sighing.

The guard walked through the battlements and headed eastward, going to the great citadel. He kept walking until he reached the throne room, where he met the big man himself, Naturus. A thousand years passed, and Naturus decided to ditch the wings, as he did not really need them at all. He was also clothed in red robes and gold

"My emperor, it's nearly time. Cadence is still amnesiac, and the Two Sisters will make their return. Starswirl the Bearded is still trapped in limbo, and we have no way of knowing where Discord is?" the guard said.

Naturus sat his one-eyed head on a hand and said Starswirl and Discord are not my biggest concerns as of now, but when Celestia and Luna return, bring them to me ALIVE!"

"Yes, your majesty..." the guard said as he walked back to his post.

Author's Note

Anyways, the Mane 6 have different names in this timeline than in the standard one, but still have the same appearances and personality.

Rainbow Dash = Prism Strike
Applejack = Applejack
Rarity = Sapphire
Pinkie Pie = Pinkie Pie
Fluttershy = Swallowtail
Twilight Sparkle = Violet Star

And yes, Cadence was still born a pegasus in this timeline, Naturus just hypnotized her into forgetting everything about her old life but her name, making her think that she was born an alicorn. And yes, I turned Spike into a Bambiraptor, because I think he'll look cute as one.
