"Sub-Level Five doesn't exist." That's the official statement of the Stairway company.

Washing out from the Night Guard program is usually a death sentence to any similar career. When Astral Sentinel was asked if he was interested in a security job, the Thestral obviously jumped at the chance.

There was just one oddity about the job. Well, there were quite a few, but mainly just one.
He just never, ever could acknowledge the existence of Sub-Level Five.

When a complete lock-down traps the Thestral inside the odd facility, he has to break that one rule. As the security systems begin to eradicate all life inside the building, Astral has to venture down to the elevators that officially don't exist, to a floor nopony alive will speak of.

He soon finds out that some things are best left buried beneath rock and stone.

"This story is simultaneously horrifying and adorable." -Witchery

Takes place far after Season 9. Although, it could take place at any time...(or in the Radverse, as some people call it.) This thing took on a mind of its own.

Seriously.

Read on if you want to join Astral for the ride.
I hope you brought your crowbar.

In later chapters, loose spoilers for Timeless, Sunspots, and Cure for a Toxin
Warnings for creepy atmosphere, gore, violence, and brief mentions of sexual content/assault (nothing explicit, only implied.)

Despite this being a horror story with unpleasant elements, it's not grimdark or a depressing tale. Lots more ups and downs, but overall it's a positive read of good vs evil, love and fluff; those are the types stories I write, after all. I just want to let everyone know what they're getting into, and don't want any readers blindsided due to some of the content.
(Not a romance involving a 'herd')

Twilight is invited to Canterlot to compete with some of the greatest magicians in the world for the Moonstone Cup, a prestigious award for the most powerful and skillful magicians, unicorn and otherwise. Can she win? What sort of competition will she face?

This story is a sequel to Timeless

(This story is a direct sequel and picks up right after Timeless ends. If you haven't read the previous story, ye be warned for confusion and spoilers!)

The sun is eternal, distant, powerful, timeless, and out of reach of any mortal creature. Like the entity she controls Celestia has curated such a view of herself over a thousand years. Having run the nation for over a millennium the Solar Princess is, to many, a revered and nigh-unapproachable figure.

However when you wear a mask for too long, it is said, you can forget who you are underneath.

While attempting to maintain a semblance of government during a devastating plague-like outbreak Celestia herself falls ill and she is all too thankful when an expert on the disease arrives to help. What the Alicorn didn't expect to find however, was how much she needed a friend more than any curative potion. Yet something about this doctor seems oddly unnatural and familiar.

As the continued efforts from a dangerous foe strive to destroy everything the Solar Princess holds dear, friendships may prove to be more valuable than any blade.

Takes place during/after Season 9

When Misty returns to Maretime Bay to upset Pipp's Nightmare Night Party, she runs into a certain somepony she "fit in" with for a bit...

Sex tag for innuendos and references to "The Act"

Written for Equimorto for Jinglemas 2022

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
Also has a TvTropes page: Split Second Tropes.

When news breaks of a dangerous mutant strand of the apple blight bacterium, which can also infect ponies, Special Agent Sweetie Drops is dispatched to Ponyville to deal with a potentially serious biohazard incident. She quickly isolates Sweet Apple Acres, and contains the danger. But preventing wider fallout will require the cooperation of a young farm filly.

This story is a sequel to The Art of Rainbow Engineering

Following Twilight Sparkle's explanation of the scientific method, Diamond Tiara asserts that the sonic rainboom is a scientific phenomenon. Scootaloo insists it is magic. The Ponyville schoolhouse is the scene for an unprecedented intellectual dispute.

It's a sonic rainboom. How not scientific could it possibly not be?

A side story to The Art of Rainbow Engineering - you don't need to read that first.

Can you make a rainbow just with sunlight and water? No magic required? With the help of the pegasus weather team, Rainbow Dash and Twilight Sparkle investigate.
