A few years back, two sisters came into town. Both of law and order, they reigned supreme over the land, one with honorable law by day, the other with ruthless vigilantism by night. The town and its surroundings lived in harmony for a time, but there came a point where the townsfolk could no longer stand the brutality of the vigilante. A disparity in punishment, and a fairness sought after. Come high noon on one fateful day, and the sisters approached each other in the center of town, they each took three steps back, and drew...

This story is a sequel to Twilight Gets a Puppy, Season 5

Now that the time travel shenanigans are finally over... maybe. Twilight, Rahs, and Spike can get on with their day to day and break in their new roomies properly, while keeping Starlight and Tempest from killing each other.
Or keep everyone from making bets about it.

Still this years not going to be any less annoying, with newborns, changes in dragon lord leadership, cutie mark crusades, Pinkie Pie being Pinkie Pie, Discord, of course, Fluttershy's brother, the battle for Rahs heating up between the six, Ogres and Oubliettes games gone mad, a massive prank war, the return of Daring Doo, added on top of the prophecy not having happened yet, and the Sparkles will again find themselves in the middle of everything.

As usual the lewd warning goes here cause of some situations and Cadence. I don't want to use the sex tag cause there isn't any and people might get confused by the current cover art.

I got dragged to Equestria by pure accident due to an experiment gone 'wrong', roughly forty years before Nightmare Moons' arrival.
No matter what I do, as a pony-changeling hybrid, something will change with Equestria. I just hope I don't doom the country before Nightmare Moon even arrives... Or worse.

This is the first story I ever tried to write professionally, so there WILL be errors, for that, I apologize in advance.
I'm editing and proofreading it on my own because I literally suck when it comes to using this site competently.
Lastly, I am a slow writer due to IRL getting in the way but I will try my hardest to settle the story down whether it's popular or not.

Fair warning, there may be spoilers in the comments.

Thank you to Little Tigress for the fantastic cover art.

A little pegasus filly shows up in Ponyville. Who is she? Other than the cutest little thing who's ever existed, of course!

I don't know when updates to this will be, other than "occasionally".

This story is a sequel to Changeling Space Program

Twilight Sparkle's experimental interplanetary drive has malfunctioned, stranding Starlight Glimmer, Spitfire, Cherry Berry, a changeling and a dragon on a hostile planet in another universe. With limited food supplies, very little magic, no communications with home, and no way to leave the planet, they must survive until somepony rescues them.

Fortunately they crashed right next door to another creature with the exact same problem- a creature named Mark Watney.

They're going to science the buck out of everything- and do whatever it takes to survive Mars and get everybody home.
