Twilight's fears over becoming a princess convince her to attempt a spell to glimpse the future. Unfortunately, she ends up doing a bit more than glimpsing; the spell turned out to be permanent, meaning she never returned back to her own time, and therefore didn't exist for ten full years.

Her absence caused a fall-apart of the elements of harmony, and Twilight is horrified to see how they've changed without her. She doesn't know how to teleport back, so she instead tries desperately to figure out what happened and piece everyone's lives back together.

We all know what happened during Lesson Zero. Twilight Sparkle screwed up big time. But she got off the hook. Nothing bad happened. No dire consequences to speak of. Nothing in her life changed for the worse.

But what if something did? After all, that’s how all fanfictions start. Just changing one detail, no matter how small. Just one minor detail. In this case, it concerns something being born inside the head our little Twilight that day.

Look out Twilight, because you’ve got a new roommate in your psyche. She’s everything you aren’t. She’s sporadic. She’s unconventional. She’s absolutely insane. She hates your guts.

Her name is Screwball.

An alternate version of the TDverse, first seen in No, I Am NOT a Brony, GET ME OUTTA EQUESTRIA!!! where after TD leaves the Gala, he comes across a certain petrified statue. Curious, he walks up to it and sets in motion a chain of events that may change the face of Equestria forever. Even worse for the wayward human, his meeting with the being known only as Discord may ensure that he never gets home...
