"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')

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

This story is a sequel to Sunspots

This story continues directly after Sunspots and contains spoilers for that story and Timeless.

When a mysterious group attacks a chemical lab, there was only one pony who Celestia and Luna knew could survive the ensuing challenge that lurked beneath earth and concrete.

Called into action against a threat that seeks to destroy both him and his new friends, Toxic Shield is pulled into the remnants of a conflict that all thought was burned away by the wrath of a Solar Empress. Many remember him as the pony with an odd voice, others, as the sole survivor of the Oakbark incident. Many call him the Iceberg. Cold, unfeeling, and without empathy, immune to both chemical agents and emotions it would seem. Very few care to explore the truth of such stories, at least until a gryphoness befriends the odd stallion.

And as a poison in many shapes and forms seeks to spread across Equestria, a reformed Windigo and Shadow Pony from the Limbo realm struggle to find their place in a world that once loathed everything they represented.
Many still do.

Severe thunderstorms are a commonality when living in a mountain fire lookout tower; an event that comes and goes with ease. However, when a storm takes a turn for the worse and causes the resident lookout to fall unconscious, the scene that greets him on awakening is about as unsettling and unwelcome as can be.
Or is it?

With his radios and cellular service cut off, Equestria's first human visitor is left to his own devices to figure out why he and his tower are now in the middle of an mysterious and dangerous forest. Well, at least the clouds still move on their own, that's a good thing, right?

Look out Equestria, there's a new human in town!

*Takes place during/after Season 9

A collaboration with: Cyberfire22

Created from a magical experiment to help Twilight around the palace, Sparks is an all-knowing hard-light entity in everything but her social skills, at least until she meets Spike. When the princess is away, he takes the artificial intelligence on a day out to see Ponyville in all its organic glory.

Up Next: S.P.A.R.K.S. Explicit

Up Next: R.A.M.

In the distant future of Equestria, Luna is recalled to Canterlot against her will to participate in a court case that will decide the future for sentient machines.

They say that good armour is a Royal Guard's best friend.

Sometimes, it might be a little more literal than expected.

After all, it isn’t every day that one receives shameless self-promotion from their protective attire.

Spike is her number-one assistant and that will never change. Even in her becoming a greater princess he has not failed in that role.

Isn't it odd how a dragon can compensate for a castle?

Twilight discovers his secret... and must save him from it.

All are condemned either to a passion or an obsession.

Twilight is desperate for love—and that desperation dooms her chances for it.

Hence The Love Protocols. Rules set in place to stop her feelings from making a mistake. Desperate enough to nearly date anyone, she needs the rules in place from getting with the wrong pony—or messing things up with the right one. 

Spike assures Twilight she's not so shallow and that, given dating experience, her tastes would narrow. Yet she requests his aid in finding love at a bar. 

How will our wingman fare in helping Twilight find somepony to love?

[Cover by Maren]

Spike has been the loyal protector of Twilight, through pen and blade, but when she sends him on a mission too dangerous even for him, he returns missing an arm. Twilight must come to realize what she truly feels for her dragon.
