GLaDOS is free of Chell, free to continue testing, when she discovers a portal gun Wheatley tried to repair with duct tape. When the portal gun catastrophically fails, the enrichment center, GLaDOS, and Chell are literally dropped in the middle of Equestria. The mute test subject soon finds the world of ponies far more welcoming than the human world. But GLaDOS sees possibilities. Let the testing begin... for science.

Finding herself unable to sleep, Princess Celestia occupies her mind by penning a letter to Twilight Sparkle. But for a weary princess, the mind has a tendency to wander...

This story is a sequel to Split Second

Twelve years ago, she broke time. Two alternate timelines exist, each with a different version of Twilight Sparkle. Both versions of her are able to see the other. In this timeline, Sparkle is a Necromancer.

Or rather, she was. Sparkle is dead now, not that she cares. She's got a new body. With Thorn (her undead dragon son) and Cobalt (her apprentice and an assassin for hire) at her side, she's ready to take on the world. Again.

This story is a sequel to Split Second and won't make sense without it.
This story also loosely shares continuity with Lupine Tree. Reading that is not required.

Most days, Princess Celestia loves her job as the ruler of Equestria. Other days, it really grates on her nerves. Between frustrating council meetings, bothersome appointments with greedy subjects, and paperwork addressing countless issues from all across the country, Celestia deals with more than her share of stress in the span of a day. After an unannounced visit from Discord, Celestia suggests an idea for how she can not only get away from her job for an afternoon, but leave behind the stress and anxiety that it comes with, completely forgetting that it even exists.
She wants to be a dog.
While such a thing might not even make sense to the reformed master of chaos, Discord grants Celestia's request. The idea may seem fun to him at first, but before the day is over, Discord may learn that being a pet owner comes with its own set of headaches, especially when that pet is the princess of the sun.

Big thanks to Red_Rover for proofreading this story of mine in such a short amount of time.

Discord takes offense to a restaurant's claim of serving "unlimited" breadsticks.

Idea inspired by the sheer ridiculousness of the Unlimited Breadsticks meme.

Originally written for the "I Regret Nothing" WriteOff.

Now with a reading by AstroBrony! And a reading by ZeusMacD.

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.

Darth Vader is one of the most despicable forces in the galaxy. Once a powerful and respected Jedi Knight, he betrayed the Galactic Republic and Jedi Order for the dark side of the Force. The newly christened Sith Lord was apprenticed to Darth Sidious and quickly became a master of the dark side. Vader was soon the scourge of the Jedi, continuing the Great Jedi Purge by slaughtering all remaining Jedi.

An extension of Emperor Palpatine's will, the Dark Lord was constantly on the move, traveling throughout the galaxy to defeat rebel uprisings and kill any surviving Jedi. This mission brings him to the edge of the Outer Rim into the Unknown Region of the galaxy, in an unknown star system. High above an unnamed planet he duels with one of the last remaining Jedi in the galaxy in a starship battle. But during the battle his ship is damaged, and he crash-lands on the mysterious planet.

With his connections to the Galactic Empire severed, Vader must find a way out the land known as Equestria, inhabited by the strange creatures known as ponies. That, or he could take it over.
