This story is connected to Equestria's End

Spoilers for Aeon Legion: Labyrinth... and not much else.

Be warned, even the prologue and description have massive spoilers for Aeon Legion: Labyrinth

All MLP spoilers are on the level of "Snape kills Dumbledore", "Vader is Luke's dad", etc. If you somehow don't know that Starlight turned good, idk what to tell you.

The first four chapters of Aeon Legion: Labyrinth are available for free here

Story available on AO3 here

Time travel has made the Edge of Time a dangerous place.

To protect the Edge of Time from devastation, the Aeon Legion seeks the greatest soldiers and warriors from across history. Those they deem worthy gain a chance to compete in the toughest training program ever designed at Aevum Academy.

Terra Mason does not know when to quit. Though consistently at the bottom of her class in every subject at Aevum, she managed to graduate with the best of the best. Though she is among the least experienced legionnaires, she has already faced down multiple temporal criminals, including the murderer of a Legendary Blade, and survived. Now, she continues her path to join the ranks of the other squires of Alya Silverwind as the greatest heroes of all Time.

Kairos has sworn to kill those who have used time travel for selfish purposes, acting as judge, jury, and executioner. The Legendary Blades are her main focus, yet her next target is Starlight Glimmer.

And Sunset Shimmer just happens to find this familiar.

Cover art modified from The Legion of Harmony - Master Starlight Glimmer by Aidelank
Despite the cover art being Starlight in pony form, there's only like 4.5 chapters with the characters as ponies

Crosses over primarily with Aeon Legion: Labyrinth by J.P. Beaubien (aka the guy from Terrible Writing Advice), but appearances from other time travel-related series are not off the table (anything from The Time Machine by H.G. Wells to Bill and Ted's Excellent Adventure and even Rip Van Winkle)

I think this is the first Aeon Legion fanfic on the internet, which by default makes it the best. If you don't like that fact, then go read Aeon Legion: Labyrinth yourself and outdo me, but please, give me a link.

And since it is the first, you can watch the fandom grow in real time either here or on AO3 in the comments, including fanon, common fandom plots, etc

It has been over one thousand years since the alicorns went extinct. Well, not truly extinct.

The centaur known as Tirek was led to Skyros by the Alicorn of Fire, and soon, Skyros fell, and with it, all of the alicorns within.

One alicorn who escaped hid himself from the world. He believed all of his fellow alicorns save for Opaline to be dead. Only now is he visited by a stranger who will prove him wrong. One who knows far more than she should.

TW: major character death

For the New Blood contest

“From the beginning, you know the end.”

“The main character’s name and identity are never mentioned.”

There’s a concept that is somewhat important to this story that I couldn’t find a good place to insert, so I’ll just explain the concept here:

Once every few generations, a special unicorn is born. These unicorns are called “Flares” for the tendency for their magic to flare up randomly as they grow up. While other unicorn foals can have magic flares (like Pumpkin Cake for example), a true flare is marked by magical power that flares up and stays up once they get their cutie mark.

During times leading up to great strife, the gaps between the births of flares would close. In fact, if threat was great enough, the gap between the births of unicorn flares could be as little as one year. If you were to measure the gaps between flare births, you could pretty accurately predict when the next threat is to occur (although Celestia, was really the only one paying attention and already knew about the return of Nightmare Moon)

Over the course of G4, we’ve become aware of not one, not two, but six unicorn flares: Twilight Sparkle, Starswirl the Bearded, Clover the Clever, Sunset Shimmer, Starlight Glimmer, and Luster Dawn.

And there are equivalents for pegasi and earth ponies, but they are much rarer

Twilight Sparkle received a human history book. Somehow, the Cutie Mark Crusaders got ahold of it and it's the only thing that Scootaloo will read. The other two are just along for the ride.

Discord is aware of humans.

Takes place during Season 6. Also takes place during Legends of Tomorrow S6E4 Bay of Squids, but that really isn't super plot relevant, even if it's the sole reason for the crossover tag.

Totally legit reviews:

I guess that was pretty funny in hindsight

Chaos.

THAT'S NOT HOW NUKES WORK! Other than that, it was pretty funny.

Average rating
★★★★★

Iteration 1 (no longer exists outside of a single google doc and the wayback machine; complete)
Iteration 2 (the rewritten version)
Iteration 3 (mostly identical to Iteration 2 with a few changes, mostly where the in-between scenes are, a little bit extra for the Pony of Shadows to do, and the removal of some bad jokes and a lot of profanity)

Currently in Iteration 2.1, but only up to Seven Seals. Everything else is still Iteration 2

Everything Involved: Loomis Comics, My Little Pony G4 (Movie and FiM), SCP Foundation, the Holy Bible (the Book of Genesis), Sonic the Hedgehog, The Flash (2014), Skylanders Academy, Among Us, Team Fortress 2, Kirby, and Undertale (the last four are debatable)

Light violence (like the kind of thing you'd see in an animated movie) should be fine without this tag.

*Laughs in Green Snake*

Anyway, time for the real description.

The SCP Foundation has been working to keep the anomalous under wraps for centuries. A single discovery may lead to their destruction.

The Crown Court has been peaceful since the Great War many years ago. The peace they have enjoyed is about to break.

Grogar escaped from his prison during Cozy Glow’s brief reign over Equestria, but before he could launch his assault, he was sent to hell. Now, with a new ally, he escapes, and prepares to reconquer Equestria.

Their destinies will collide, worlds will die, and the multiverse will never be the same.

Death tag because in chapter 7 alone I killed 5 billion people. The death count otherwise is in the triple digits range.
Violence and gore mostly in the final chapter
Profanity because... why not
Chessmaster is the final chapter packed to the brim with "comedy". From Temple Peak onward, the subplots have very little comedy while the main plot keeps its "comedy" all the way until Destiny (does not apply to Iteration 3)

Totally real reviews:

Comedy is trash, doesn't represent the struggles of trans people in Ukraine, barely even has My Little Pony in it. Then again, you perfectly encapsulated my sense of humor.
-P.R.U.A.L.C.S.
★★★★☆

Literally just trash. Would give zero stars if I could.

-King Minos
☆☆☆☆☆ (rating pending)

I think I shat myself

★★★★☆

Not nearly enough adult jokes, but have a five star anyway.

Please stop, we all know you're just wanking your OCs at this point
