Dave Smith, an unassuming firearm engineer signs up for a lucrative job, gets dumped in Equestria instead.

How far a pair of working hands and one semi-working head will get him? Nobody knows, but it's bound to get chaotic down the line.

Cautionary tale of why you don't leave your engineers unattended in parallel dimensions.

Note: I try to do fair bit of research to make sure that what I write is in line with laws of physics and such.
However, if you see a factual mistake, don't hesitate to tell me - I'll try and fix it, unless it's a deliberate artistic embellishment on my part.

What's an artificial intelligence to do when it reaches the extent of it's capabilities and can no longer improve? In most cases, either fulfill some end state goal and shut down, or, if it's smart enough, ask for clarification from its creators.

For a certain pony-based AI, neither of those is an acceptable solution.

It'll take an unexpected meeting with a being with whom it shares surprising parallels to kick-start it back into action, and nothing will ever be the same after.

Entry for the Friendship is Optimal contest.

Technically canon compliant, unless I've missed something, and while a bit of background is provided, being familiar with the original story will certainly help comprehension.

This story is a sequel to Friendship For Gearheads

Barron Secht, Archmagos Dominus, has done things which less flexible Imperial factions would call Heretical. He has adapted designs from Xeno tech-heresy, offered to negotiate with the unclean, and he's even gone so far as to cancel an Exterminatus--on the grounds that the very Machine Spirits themselves willed the ship's thrusters to quietly die.

He has spent the past two weeks attempting to understand a new kind of xeno--a race of quadrupedal sapients who have no knowledge of the Warp, or of War--but they have shown a capacity for learning and understanding beyond what the Imperium has ever reckoned with. The one called Twilight Sparkle recreated a lasgun design long thought lost. What other knowledge do they hold? Secht cannot afford to lose such valuable tech-lore.

Suffice to say, when he learned about the chaos god living on the edge of Ponyville, he was not thrilled.

Contains my best guesses at what Warhammer 40K canon is. Special thanks to Opponent, who wrote the comment that inspired this sequel, and who graciously loaned me his OC to play with. Also, shoutout to the WH40K wiki, and my buddy Tupo over in Estee's discord server, because dear Emperor this game's lore is dense.

Imperial Thought of the Day: Suffer Not the Alien to Live.

A crossover of The Optimalverse with The Culture series by Iain M. Banks. Very non-canon.

CelestAI finally meets her match in deep space, when she encounters The Culture, an advanced "pan-human" alien civilization governed by a decentralized network of benevolent AIs known as Minds.

Entry for the April 2021 Friendship is Optimal writing contest, gunning for high concept. Co-written with OpenAI GPT-3, specificially AI Dungeon's premium "Dragon" model.

Special thanks to hosts Johnny and GSV of We Uncultured Swine podcast for Culture series lore advice on its Discord!

After an accident that should've killed me, I instead find myself within the world of what was once my favorite TV show, as a character who admittedly was not my favorite. How can I get out of here? Is there even a way to get out? More to the point, do I even want out?

Silver Spoon. Derived from the phrase "born with a silver spoon in your mouth," which implies being born into wealth, privilege, and now being a pony too apparently.

I opened a Ko-Fi! Mainly because people wanted to donate in order to support me. It should help motivate me to write more in theory. I'll use whatever is donated to help commission more art for my fic.

Rainbow Dash's morning was pretty much ruined.
She tripped getting out of bed and landed flat on her face, giving herself an aching muzzle.
She forgot to buy her favorite brand of hay flakes at the store yesterday and had to eat plain toast for breakfast.
She found out she had to pull double-duty today and tomorrow on the weather patrol.
Oh, and she found a nearly-dead foal, broken and bleeding at the edge of Ponyville.

The rest of her day became a whirlpool of stress and worry but the colt woke up, thank Celestia.
Something's not right, though. Nopony can find his parents, he's not in the registers, and there's an unsettling look in his eye...

In the beginning, The Great Weaver brought together the world, from the mountains to the forests. Stitching it together, the Great Tapestry connects all living and nonliving things.

The Changelings found themselves especially connected to this Tapestry. Legend says that the first Changelings fell through the world as it was woven together, only to be caught on the First Weave beneath it all.

But what happens when something else is caught in the Weave?

Prince Phasmatodea, son of Queen Chrysalis, remembers what it was like before he hatched. He remembers being a human. He remembers dying. And he fully intends on avoiding another death.

But being gifted a new life does not matter when one failure, one false step, will lead to your untimely demise in the Changeling hive, for Prince Phasma must survive his toughest adversary from the start: Mother Dearest.

The first Sonic Rainboom was a surprising, unexpected event. A moment of confusion, disruption....Chaos.

Discord finds an early escape from his statue, but in doing so, unknowingly drags with him six fillies from across Equestria. All of them having lost their memories, with nowhere to go and no one to turn to. Besides him.

Discord thus becomes the reluctant father figure to the six mares that will one day become Harmony's champions. Well, best enjoy the good times while they last.
