Full Metal Pony

There was darkness.
No sound.
No light.
No life.

Fluttershy seemed to be floating, as of on a cloud, maybe in water. She looked around, and saw nothing. Holding a hoof to her face, she could see herself clearly. But there was nothing.
Applejack was could have been in another dimension, or even just beside Fluttershy, but saw nothing except the black. Straining her eyes, there was nothing visible. No walls, no other ponies, no sky... clouds... earth...
Rainbow Dash looked around, the darkness clearly not totally dark. For a second, she had seen a rainbow, but that was merely her mane floating in front of her. Maybe they were in space, being sent into the moon. Or, perhaps, was this what Discord went through being imprisoned in the stone?

-~-Meanwhile in Equestria-~-
Twilight and Pinkie pie, on the other hand, just stood there. Pinkie bounced over to Princess Celestia, who lay on the ground, breathing heavily. The venom from the snake bites that Chrysalis delivered was setting in at an alarming rate, and she was losing blood fast. Looking around, Princess Luna saw that Queen Chrysalis was nowhere to be found, all the changelings that were once flooding the palace grounds had vanished, retreated... who knew at this point? Twilight was feeling completely drawn out, taking all her energy to slowly trudge over to Celestia. "Princess, I... have calculated... that what the others.... went through... was a worm...holing..." she spoke, panting every few words. Her breath was running short, and she slowly fell over, fast asleep. Several royal guards raced in, a chariot waiting to take them all to Manehattan that was the nearest hospital. Celestia had a larger medical chariot to stabilize her, and the others tagged along in a normal, transport cart.

-~-Meanwhile in the Void-~-

Fluttershy saw a small light up ahead. Was it the way back to Equestria? Maybe, just maybe... She floated directly into the glowing portal, and the world went back again. But she heard something. Squeaks? Barks? Chirps? It was all of nature calling out to her. Slowly, she woke up. The void, it was just a dream. She let a sigh of relief, and got out of her bed, answering all the calls of nature. But she looked out, and her heart stopped. All brain functions seemed to cease. Breathing became impaired. Looking out, the animals were not calling out to here; they were screaming and running, running from the forest fire, running from the changeling army, invading peaceful Pony Ville, the defenseless town in the invasion force's way. And she passed out at the horrifying sight, waking up floating...

Into the Void.

Applejack was waking up from a nap under the biggest, shadiest apple tree on her farm. She tilted her head up, and the sky was black. Looked almost like storm clouds, but the inhaled through her nose, and her eyes began to water. Smoke and smoke means fire. She traced the direction of it all due east. Her house. She raced towards to all, eyes burning, lungs burning, legs burning. But she was too late. By time she had gotten to the house, fire was spouting from every window, every door, and every hole in the boards. She darted between flames and into the house, just long enough to see if any pony was in there. She called her list of names, starting with Granny Smith, ending with Applebloom. No answer. She turned around, but there was no doorway; a wall of fire took its place. Looked to her left - flames spreading and closing in. Right - exact same. She heard the floors creaking under the stress of weight, and looked down. But it wasn’t the floor creaking. A roar erupted, and the burning, white-hot ceiling crashed down on her, sending her, too...

Into the void.

Rainbow was flying back from Phillydelphia, where she had the best concert of her life. Iron Mare, best seats on their 'Peace of Mane' tour. She raced back home, eager to show Scootaloo the guitar pick she managed to catch in a miracle event. But she came home to fire, smoke, debris everywhere, and an army of changelings overrunning he town she called home for so many years. She could handle the war, and this was close to breaking her, but that’s when she saw it. Scootaloo weeping, in a shaded area away from everything else. Looking over, she saw the forest on fire, and thought of Fluttershy, and all the animals. Then she noticed a trail of smoke from Sweet Apple Acres, and realized it wasn't just the main areas, it was the entire town. She was almost to Scootaloo, when she felt her hoofs go out from under her, and looked up to stare a changeling dead in the eyes. His horn started to glow, and her vision started to burn, from outside in.

Fading into the Void.
