Equestria's history is full of wonders, both magical and mechanical. But only twice has it succeeded in implementing AI.

The latest iteration is an apple farmer whose resurrection is celebrated by everypony except herself. Because really, once every part has been replaced, what is left that can measure a mare?

An entry for the 2023 Sci-Fi Contest, where it nabbed a respectable fourth place. Yay, existential robot ponies!

Time is a neutral party. It takes no sides, only proceeding without a care for those caught in its trap. That is how it should be...
But not all traps are foolproof.

When a pony seeking the Night Princess's counsel intervenes during an assassination attempt, Luna knew there was more to this stallion than met the eye.
However, even her expectations had limits. That, Luna discovered, was a mistake.

One question troubles her thoughts as a new problem presents itself in the form of this stallion; how does a heart and mind cope when one escapes the trap of time? What happens to a good heart when it is worn away, year after year, all stemming from a single mistake, no matter how good the intentions?

Takes place during/after Season 9.
Sequel: Sunspots

Peace has been restored and all is well in Maretime Bay once again. But that doesn't mean things have gone completely back to how they were, some things still need to be addressed.

Among them is Sprout's actions as emperor, and Hitch wants to make sure Sprout learns his lesson. To that end, he has his former deputy arrested and put in jail, much to Sprout's shock.

But Sprout will be even more surprised when Sunny of all ponies comes to visit him. Yet Sunny's reason for the visit is not what Sprout will be expecting. There's something very important Sunny wants to teach the stallion who used to be a childhood friend of hers.

(Featured from 1/17/22 to 1/18/22. Has an audio reading on YouTube which can be viewed here.)

Sequel: Left Behind: Sunny Disposition
Apparently it was scouted and is on EqD too

Nightmare Moon was meant to be released after a thousand years. A momentous occasion for her but terrifying for all the ponies on her day of freedom. She would get revenge on her sister and cover the world in darkness and shape everything to fit it.

That was the plan, at least. Instead, something went awry with the spell and she wasn't released when she was supposed to be. The mare-in-the-moon is brought into a world with stagnated technology, giant cities, and no sign of her sister or any of the other immortals. In fact, ponies don't seem terrified of her at all, and the stay within the core of her powers infused and changed the alicorn's body drastically.

The alicorn had no obstacles left! But...she was also a relic of the past. A past everyone seemed to have forgotten. A past she could no longer look upon.

Story takes place post FIM and EG

When Twilight Sparkle had the magical surge that cemented her place as Celestia's student, the amount of power she released not only hatched a baby Dragon, it brought forth something else. Something that shouldn't exist any more.
Something that has Celestia worried.

A fluffy puppy.

[Despite the gore tag it's rather light on that, and they have yet to make a lewd tag and there's a bit of that.]

Season two is live here, Season 2

This story is a sequel to The Mask of Despair and the Face of Hope

Life has been calm of late for Luna, but calm does not mean entirely content. She’s lonely, and although her relationship with Celestia has never been better, there’s only so much time between dawn and dusk and Equestria needs it’s leader. What spare time Luna has is usually spent alone, and her duty is complicated by Twilight requiring extra help to deal with the trauma she suffered from an incident involving time travel and the end of the world, which was thankfully averted.

One night she spots a stranger in the night sky and finds them to be a newcomer to canterlot. A Unicorn with magically generated glass wings, and strangely lacking a cutie-mark. It’s only after she starts to coax him from behind his mask of despair and befriend him that she discovers that something is eating at his mind, possibly literally.

What does his condition have to do with his two strange silver face-masks? What connection does he have to Twilight Sparkle’s trauma? Why can’t she find his dreams as he sleeps? Why does it feel like so much more than the fate of a single pony lies in his fractured history?

There are shadows and storms ahead, and the destiny of more than one world may hang in balance.

Twilight finds out something isn't quite right about the crystal castle and herself. When she learns that something has changed about her and she isn't who she thinks she is, she tries to find out why and how that came to pass.
The answers isn't what she expected, but now that she knows, what will she do with that information? Will she change, continue, or end it all?

This is a prequel to Screwed AGAIN!!

Everypony think Shining Armor is useless, that he's lazy, or even that he flat out doesn't do anything. Shining could prove them wrong, if he had the time. He does more than they think.

Join the Captain of the Guard as he deals with a completely normal day. Well...normal by his standards.

Star Kicker is the newest member of Princess Luna's royal guards, and she has a lot to prove. After all, she has to show once and for all that she's better than her stuck-up skunk of an older sister. Fortunately for her, Luna is eager to give her the chance.

In the desert kingdom of Selerika, the tomb of one of Luna's old friends has been robbed and a priceless artifact stolen. Luna is determined to recover it, and who better to bring along than a unicorn whose special talent lies in finding lost things? It's a dangerous adventure full of mortal peril, but that comes with the territory of being a royal guard.
