Sunset was surounded by white. There was no distinction between where the ground ended and the sky began. there was nothing but white, it hurt to look at it so she closed her eyes.
"Where..am I?" she wondered out loud.
Where do you think? a voice replied. it sounded female a bit deeper than pinkie's but higher than say, Princes Luna's.
"Who are you?"
I'm the mare who watches over and repairs the fourth wall
"Uh...What?"
What you know as the fourth wall is barrier of energy between all dimensions, by breaking it you can see and know things that lay beyond that barrier. It my job to ensure that each time it is broken it does not reach the point where it can no longer maintain itself and cause total event collapse the voice explained with an air of maturity and wisdom.
"The entire Multiverse?" Sunset asked
Pfft don't be stupid. I only watch over a small portion of it. I'm not the only one you know
"Oh right sorry, so are we in the fourth wall?"
Yes, I had to bring you here so your little revelation didn't shatter my section of the multiverse
"Sorry"
It's fine, you have an intersting mind you know. Tell you what, I'll send you back so you can make that deal with time weilding vixen if you promise to be my friend in your new life alright?
"Ok Pinkamena"
Oh you're good, nice meeting you Sunset Moonfire*.
