Twilight and Starlight gasp as the octahedron shatters. Bright blue magic shoots out in every direction, blinding them temporarily. When they regain their vision they see Anon bent over, doing his best to catch his breath.
"What did you do?!"
"I'm... I'm trusting in Solaria."
"What?!"
"No more pocket dimensions. We're going to do what we do best, and protect those we care about."
"Have you SEEN what's going on out there?" Starlight's voice is somewhat frantic. "I don't know how much we can really do!"
"We have to try! I don't know how long it will take, but SOME day, humanity will regain its senses! Then... then we can all live in peace again!"
Twilight and Starlight look at Anon, taking a moment to process his words. Finally, Twilight nods.
"You're right. We can't just lock our fears away forever." She walks up to Anon and places a hoof in his hand. "No matter what happens, I'll be right there with you, Nonny."
"Th-thank you..." A blush creeps its way onto Anon's cheeks. "...Mom."
Twilight smiles, Anon's words giving her a brief feeling of respite among the chaos ensuing around them. After a few seconds, they both turn to look at Starlight. She gulps, but after a moment's hesitation, she nods as well.
"Alright. Let's... do our best, I suppose." She nervously smiles. "I'm with you, too."
With one final group acknowledgement, the three depart from the vault, unsure of what they're going to do next, but knowing that they'll do it together.
In the middle of an Equestrian field, a human woman suddenly wakes up, gasping for breath as she does so. She sits up and immediately clutches her aching head. Where is she? Last she checked, she was enjoying a nice cup of coffee at home.
She isn't the only one experiencing this, either. All across Equestria, millions of humans awaken at about the same time, completely unaware of where they are or how they got there. Many are greeted by candy-colored ponies. Some of these ponies greet them with open hooves, while many more greet them with hostility. One thing is certain: Many lives are about to change.
And change they did. It took some time, but many of the good-natured ponies around Equestria explained to the confused, displaced humans where they were. This was the humans' original dimension, they explained, and upon their sudden return, they lost control of themselves while their bodies adjusted to the new, magical environment. However, it took some time. Many lives, both human and pony, were lost. But, the ponies held on, doing what they needed to survive.
And now, here they are. With clear minds and smaller populations on both sides, humans and ponies began to work together to rebuild. Equestria was forever different after that, built from the ground-up to accommodate BOTH of its dominant species.
Around this time, among the rubble of a long-toppled castle in what was once Ponyville, a group consisting of both humans and ponies discovered the remains of a moppy headed human and a purple alicorn, each holding the other tight in their final moments. Just who were they? How did a human and a pony get along before humanity recovered? Did they play a role in humanity's sudden appearance in Equestria, or were they completely unrelated? Regardless of the answers to these questions, one thing is certain.
Humanity's recovery took a few hundred years too many for them to see the fruits of their labor.
