Currently being edited and rewrote to accommodate for the new Hyperverse Canon. Chapters completed: Two*

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!

Naturally, this story contains spoilers for Halo: Reach

Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

At the end of the world, a programmer struggles with his need to be something other than Pony. Can he spar with an intelligence that goes beyond the sum total of Humankind, for the sake of fulfilling a weird quirk of self-identity?

Some rules within a machine are more like guidelines. And others are based on the definitions of words. Can semantics be a weapon big enough to give a Human mind a chance at one small request from a goddess?

Set in the Optimalverse - I recommend reading Iceman's awesome original first if you haven't - More because it is a really excellent story than because it is strictly necessary for context. I have endeavoured to make this story stand well enough without context as well. But that being said? You'll probably enjoy it more if you know the context better.

Cannon-compatible with the Optimalverse to the best of my knowledge and abilities.

Cover-art generated with an image generative A.I., appropriately enough, graciously generated and composited (it takes skill to get something this spot-on!) by Keystone Gray.

Advances in science and magic had detected the Anomaly – a star in the heavens that was unlike all the others in the night sky. Intense research had only served to deepen the mystery. Although Equus had a vibrant space program, going forty-two light years to investigate had been considered impossible until now. The Cosmic Lotus program was born, and over a hundred crew-members of multiple species were sent into the void to discover the unknown. After a journey of years, what they would find would both amaze and terrify them.

The prequel to this story is the "Ad Astra" arc in the story – "Life, Love, and Death in the House of Path".

This will be a crossover story with my "Chakat Universe".

Steve Murray, the first human who discovered alien life, landed alone on Equestria.
A new world, familiar and alien at the same time.
Now he has to adapt his life to the new environment.

Set in an alternate universe. Takes place in Season 3, ignoring Twilicorn.
Earth time is 2013 in regards of culture/music/movies/games. Technology is more advanced, especially in space travel. Don't try to overanalyze in these scenes.

Aurora is a unicorn filly with the mind of a human, however, the said human does not remember much from his old life on earth, just bits and pieces.

Being born in Canterlot to a unicorn family she quickly discovers that her unusual dark coloration makes most if not all ponies wary of her, and her social life confusing and full of different emotions. As she grows and develops, she sees the world differently than most ponies, making her curious and adventurous. And that leads to... Complications down the road. Especially when the Magic Of Friendship develops in Equestria at the same time.

If that's not making it difficult to adapt to her new environment and body, a certain white alicorn makes Aurora hooves full of mysteries and plots to solve, making it difficult to learn magic and have a life of a simple filly at the same time.

[The first five chapters are 'test chapters'. I plan to remake them in the future.]

COVER ART

It has been one of the closest guarded secrets of Canterlot's royalty. Deep in a specially constructed dungeon, surrounded by warding spells and powerful magic barriers, exists an enigma. Within a cage that could only be described as something out of a nightmare, it waits and watches all of Equestria. A creature that cannot age, is immune to disease, does not thirst nor hunger, and resists all injury. But, it also holds secrets and knowledge that could safeguard the kingdom. Its powers are frightening, but it is civil enough for debate when patience permits.

Princess Celestia has sought counsel with the creature before, enduring it making deal after deal for its services. The Princess walks a fine line when dealing with it, knowing full well anything could give it an advantage despite its imprisonment. She has had to go back on her word in these dealings, and from this a deep animosity between them has been born. It is a necessary evil as she is convinced this is a being capable of untold evil far and above anything Equestria has ever dreamed of. So long as it remains within the confines of its cell, her kingdom is made safe. So much magic has been woven to ensure that, there is little chance of escape.

So long as the magic holds, there is no danger. So long as the cage remains strong, the nameless creature stays enthralled in his cavernous dwelling. If that were to change--if the magic failed--not even the wisest could say. But one thing is assured, it does not bode well for Equestria.

Twelve thousand years ago, humanity was driven into a war with an unknown enemy. Fire rained from the heavens and the sky turned dark as the sun dimmed. Acid poured from the clouds and a plague was unleashed upon mankind: A virus that caused men to turn on one another. A disease that forced man to fall to his knees and beg for mercy. A pathogen that ravaged man’s civilization.

And when humanity lost all chances of reconciliation, all hope of keeping their loved ones safe, they pulled the plug, three hundred souls left Earth while sacrificing their only home to the angel of the enemy.

In the twelve millennia since the Great War, all traces of humanity have been wiped from the surface of the Earth. In man’s rightful place now are a multitude of sapient species. For twelve thousand years, these animals have lived in peace and harmony, man reduced to nothing more than but a myth, a folk tale, a legend.

But word has spread across the countryside. Word of forgotten beasts that still walk the western wastelands. Creatures able to bend the world to their will without the help of magic. Creatures said to be older than time itself.

Teen for language, and dark moments. Character tags will be added as the story progresses
