The following transcripts are of a journal found in Ponyville on April 16th of this year. The last recorded contact with the town had been 3 days prior, on the 13th, when a team under orders from Princess Celestia was sent to look into several missing pony reports in the area. When another group of investigators were sent on the 16th, the town was found deserted. The journal’s owner is believed to be the princess’s personal student, Twilight Sparkle. None of the town’s inhabitants have been located in the weeks since.

She was a unicorn on the run. Being hunted, her only option was to hide where they wouldn't think to look. Once over the border she'd hide in the most quiet, boring, unassuming town she could find in Equestria. Her information was out of date but how much could Ponyville have changed?

Once there all she'd have to do is keep her head down and not draw attention to herself. Certainly stay away from any adventure or authority figures, top of which being the Princesses. She'd shuddered to think what would happen if they found out who she really was. Still, what were the chances that she'd be dragged into an adventure or meeting any princesses while in Ponyville.

Thank you to 'Greynoise' and 'Starlight Nova' for editing and pre-reading respectively.

After a long day, Octavia goes home and pours herself a stiff drink.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
