Sombra never realized this would happen.
Usually a villain is suppose to be defeated, right?
So, why did he, well...win?
Even he was shocked to see the crystal heart in his hooves. Never in a thousand or so years did he think he would pull this off; that he would actually...win.
So, what will he do now? Just rule over everyone and enslave all of pony kind? Or Perhaps kill the princess and mind control that purple unicorn and her friends? Or maybe have some common sense and figure out just how he will deal with all of this in the long run? With all these questions, he knows one thing for sure.
This is going to be very awkward.

When Sombra, ex-ruler of the Crystal Empire, is discovered alive and well, Twilight has her hooves full keeping the tyrannical king in check. Instead of the original plan of throwing him in a dungeon or banishing him to Tartarus, Celestia decides to go with the plan that worked out well enough for Discord.

To reform Sombra.

Pinkie takes the job, and gets right to work in helping Sombra become a better pony. Will Sombra finally change from his old, wicked ways and reform? Or will he instead strangle the annoying, pink menace known as Pinkie Pie?

"Humans.... Quite possibly the most infuriating mythical creatures in existence. If you ever have the 'luck' to meet a Human in your travels across Equestria, then you must be careful. Humans are extremely powerful creatures, some would say more so than Celestia or Luna, they are also more unpredictable than Discord. They can help you in a tight spot if you're lucky, or play nasty tricks on you if you don't hold the Human's favor. In my time I've seen a Human give a filly pounds upon pounds of gold, and the same one turn greedy ponies into gold. The only one I ever have seen 'face-to-face' was in my earlier years, he helped me repair my wagon when it broke down in Everfree Forest, by fix I mean a whole new one appeared not ten feet away, and the only thing the Human asked for in return was a spindle.... But be warned, never anger a Human, a trick or two in fair game is fine, but if you ever manage to truly anger a Human...... you'll be part of the small number ever to meet non-existence." - Star-Swirl the Bearded.

A silly nonsensical story, not to be taken seriously. Some chapters are not connected to others.

Celestia wants Twilight and her friends to loosen up a little bit around her. Luna just wants to try the hard cider. During a surprise visit to Sweet Apple Acres at the tail end of cider season, Princess Luna has just a bit too much to drink, and when she makes a rather inappropriate joke, Twilight comes to the very uncomfortable realization that she has never seen Celestia excuse herself to use the restroom.

Twilight is known for many things: being the shrunken student of Princess Celestia, an adventurer, powerful magic user, avid learner and reader, and more. But one thing she's never been is a prankster. When she learns about the holiday known as "April Foals Day" she decides to take part in the holiday and prank her closest friends and family for a few good laughs.

This story is a gift to my friend CommanderX5, the writer of Celestia's Tiny Student. Note that this is in canon with his story and takes place after Twilight's duel with Celestia, but before she meets the Wonderbolts.

When a mishap occurs with Celestia's bathroom scale, an ancient protocol that may just doom Equestria is set into motion. With the entire palace staff now conspiring against her, the sun goddess must not only contend mountains of paper work, dancing celery sticks, and steroid pumped stallions, but a sister who will take this chance to torture Celestia any way she can as payback for her banishment. Lock the cupboards and barricade the fridge! It's the Royal Diet!

So, what is it that makes this night any different from another one that she has lived through? What strange occurrence occurs that makes it stand out? That changes her life forever? That changes the course of- Oh you get the idea.
