"The.. the White what?" asked Rainbow, her ears lifted.
"The White Void."
"..." She frowned, "where did reality go?"
"It didn't go away... it is still here."
"Where?"
"It... it is here I'm sure," Twilight moved her hooves, trying to explain where everything had gone. Of course, she didn't have idea of what she was doing. "Well..." she growled, put her googles off her eyes and on her poll and continued, "it is hard to explain."
"Hard to explain, HARD TO EXPLAIN?!" Rainbow yelled, taking Twilight aback at the sudden outburst. Rainbow noticed this and sat in her haunches, trying to ease her mind. "Sorry, it just that... I thought we were dead and then... you have the explanation... and you don't want to say it to me."
Twilight's ears dropped. She sighed, "Imagine that reality is made of layers, like a cake, to put it easy. Some of those layers are all put over the main one -that contains us-, we can't touch what is in them and they can't touch us, however, they can see us. An example of a creature living in one of those layers could be a ghost that can't go to the Heavens and thus is lost, it can see us, but it can't touch us, because it don't belong in our reality.
The White Void, for the little that I know about it, is completely different. It isn't attached to our reality, as we call it, nor does form part of an alternate universe. It is like a... a crumb. It is a... reality in itself, it does not follow our rules of time and space. And it doesn't affect us.
Now, jumping back to our respective reality would take us a lot of magic, not only because isn't attached to it, but because it belongs in a different timeline and..."
Rainbow Dash's eyes slowly went different ways.
"And you're not paying attention, right?"
Rainbow shook her head. Her eyes glowed briefly.
"Cumoh socatod ha nos ginaronaic tu."
"Euh?" asked Twilight.
"Sacitog seuvort es seet," Rainbow continued. Out of sudden, her eyes returned to their normal state. "Guy, that was weird."
"Rainbow."
"Yes?"
"You... you were speaking the Ancient language. I didn't understand what you said bu-"
"What is that?" Rainbow questioned, "wait, what was with the cake and all? Aren't there supposed to be, like, multiverses or something?" she said, changing the subject.
"I think that, for that matter, this place belongs in all universes and at the same time in none of them. Nopony has studied reality deep enough and it's hard to find books about that that aren't plain dumb and that actually explain something that matters."
"Yeah, whatever. How do we get back to Ponyville?" asked Rainbow, waving her foreleg like nothing important happened.
She looked to the floor and, for the split of a second, Twilight could swear she saw something wrong in Rainbow Dash, something so obvious yet she couldn't tell what it was. "Uh, Equestria to egghead, how do we get back?" she asked again.
"Eh, uh, oh..." she shook her head, fog clouding her mind. "Oh, yeah. Well, you see, it took me an enormous amount of magic to cast the spell and it..." she gulped, "nearly killed me," she kicked the nonexistent dirt of the floor. "And... we... we can't..."
Rainbow's mood dropped instantly. "We... we can't come back?"
"What? No!" Twilight yelled, "of course we can go back, but that would require somepony strong enough to open our way back to Equestria. If I am correct, magic doesn't work there due to the lack of magical frequencies that unicorns use, but one could use magic if-"
"Twilight, look!" Rainbow pointed behind her.
Twilight, expecting by instict something dangerous, turned around to face whatever monstrosity could be there. Instead, she found a sign with the words "0 miles" written on it.
Rainbow Dash flew towards it. "Does this mean something?!" she asked, excitement written all over her face.
Twilight rubbed her temples, "I don't know..."
"Maybe we should follow it! Maybe it can lead us to an exit!"
"Wait, Rainbow!" Twilight screamed, watching as her friend disappeared in the distance. Seeing no other options, Twilight ran behind her, following the rainbow trail that her friend left.
But she knew, in the deepest of her mind, that something was wrong. 'Mal sebata otod'
Twilight turned around, only to find nothing to worry about.
'I swear I heard somebody...' she thought, before resuming her race to catch up with Rainbow again.
