There is a legend. A legend of six heroes destined to protect Equestria from danger. But these six are not the Elements of Harmony. They are more.

The Steadfast Commander.
The True Genius.
The Vigilant Eye.
The Merciless Wrath.
The Fighting Spirit.
The Lone Wolf.

They are the true Protectors of Equestria.
They are the Guardians.
They are Noble.

Alright, so here is the story I have teased on my blog, The Noble Guardians! If you already guessed the concept, good for you! But for the rest of you, this is a Halo: Reach Crossover. I have seen a couple fics in which Six or Jorge are brought to Equestria, but they were always alone, so I decided to bring them all together as one. This will follow the show's storyline, with Noble acting as additional characters to the episodes, but don't worry, I guarantee they will be major characters with their own arcs and there will be plenty of original situations. I will also most likely skip any episodes in which Noble would have little to no involvement. (This will be few and far between, one example being "Call of the Cutie" I mean, even the Mane Six are only minor characters in that episode. I'll probably either mention those in passing or have another story going on with those episodes occurring in the background.) Anyway, see how Noble reacts to becoming Equestria's destined protectors!

Rated [Teen] for F. Violence & Strong Language.

It's been ten years since she's been crowned princess, and during that time she's been rather... busy. Among moments of solving friendship problems and saving Equestria multiple times, she has destroyed the covenant, saved the Mushroom Kingdom and its princess, destroyed all the colossi in the Forbidden Land by the order of a sealed god, escaped Black Mesa, and many more heroic deeds. Yes, Twilight Sparkle can call herself a video game master of many genres. However, she never once touched the aspects of virtual reality MMO’s. That is until she started playing Equestrian Earth. With a whole digital world before her, Twilight felt that her adventures in the MMO would be her greatest adventure yet.
However, this adventure may prove to be the most dangerous as a powerful entity and its legion of hackers have taken over the world. Twilight Sparkle must unite with her fellow gamer friends if she is to prevent herself from getting a game over not just in the virtual world, but the real world. Adventure awaits in a land filled with monsters, allies, quests, rivals, imagination, friendship, and magic.

This is Equestrian Earth, let the games begin.

Ω SLthethird's review

The year is 2154, Humanity is on the cusp of interstellar travel, with the earth united under a single banner. Then an anomaly is detected, 0.75 light years from the sun a Wormhole has formed, large enough to swallow a planet and stable enough to stay open for years at a time, in a rush of scientific progress a vessel is built and crewed with the cream of humanity, the best astronauts from around the solar system.
Then it sets out across the stars, a physics defying engine driving the ship towards this gateway to places and times unknown.

A universe away, a purple coated unicorn trains her telescopes to the night sky, and notices a strange object in the sky. A hole in the endless dark between stars, through which another dimension can be seen.

It occurred one peaceful night. Half of Equestria awoke to the sound like a double-shot thunderclap. A percussion heard in the skies and rattling windows from Apploosa, to Canterlot, to Ponyville. Nopony knew what it was or what it heralded for the world as it drew a line across the nation.

For Twilight Sparkle, this isolated incident might have faded from memory after a time, if not for the strange rumors of a creature sitting on the hill on the outskirts of town.

These are her thoughts given written form. These are Sparkle's Notes.

Report EVERYTHING to the Princess.

The Reaper War was a harsh and cruel mistress to the galaxy. Trillions of people died. Thousands of worlds burned. Annoying reporters got kneed in the stomach. But above all, tales of heroism; the Miracle at Palaven, the evacuation of Uqbar by a single Alliance ship, the reconciliation of the geth and the quarians over a century-long feud.

But above all else, the N7s.

While not technically N7s, Alliance Command was willing to let the name be used. The N7s were balls-to-the-wall hardcore badasses; four of them were usually enough to hold a position against endless waves of indoctrinated humans, rogue Geth, Reaper Husks, or Collectors, made of a species long passed. No species or gender was restricted because no species or gender was safe. And one of these teams - Aleph Squad, a six-man testament to diversity and asskickery, was one of the best of the best.

After the end of the War, however, Aleph Squad went MIA. Nobody knows what happened to them. Not even Aleph Squad knows what happened to them. All they know is this; something went really wrong with the Crucible, because now they're stuck on a planet full of colorful talking horses and they can't get off.

Co-authored with Gideon020 Big thanks for his help with this story!

Buried in the stone beneath Canterlot, an ancient secret is about to be uncovered. One that will forever change Equestrias view on the places beyond the stars

Going far from the Galaxy we call home.
A faint gleam of hope and a promise of knowledge.
Farewell, Equestria, farewell, beloved ones
Bearing the fate of the Elements.
These ponies fight and the romance burns high
Somepony has got to do this
If we are the ponies they count on...
Going far from the Galaxy to space unknown.
A faint gleam of hope
The Space Battleship Yamato

In the depths of Equestria's archives there is a song. A song of a legendary hero, who would keep evil at bay, and rout even the most fiercest foe. This hero was said to have the blood of dragons flowing in his veins and a heart filled with fire, who could command the world with his voice. Not much is known about this song or it's origin, but when a curious purple unicorn discovers it, she decides to put on a performance for her closest friends and her beloved mentor. Little does she know the power and significance of this song. For better or for worse, this is the Ballad of the Dovakhiin.
