Switching between two characters, one human, one a pony, this is a fictional tale of the clash between two worlds. A human, former pilot for the Unites States Navy, tells the story of the war with Equestria, after a mysterious rift opened between the worlds. At the same time, a Pegasus pony describes his time in the war, and how he served in the EAF (Equestrian Air Force) under his commanding officer.

(Teen for some shipping and some violent moments which include blood and war.)

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

The mission was to eliminate the final members of Raven's Rock that survived the purge in Russia. When they were heading to the evac point from a mountain range in Northern India where the final member of the Ultranationalist was eliminated they had to go through a strange cave that was supposed to open into a clearing where a helicopter could easily land, but there was a portal to a strange land where sentient equines roamed how will Kozak and Hunter squad react to this new enviroment? Eventhough they are a Ghost Recon team what will they do in a land that was thought to be a fairy tale world?

Golden eyes and a large, curved front tooth were the first give-aways. I was changing and I knew it. I was changing into the monster from my dreams, no, my nightmares.

That wasn't all though. He left me a last little gift as he called it, sending me into a deep slumber only to awaken inside the room of a large white horse with a horn and wings. And she did not look happy.

Adjusting to a land filled with ponies is hard, adjusting to a land filled with ponies whilst you can feel your body and mind change is harder.

I had hoped that if I write down my memoirs I would escape him, escape his influence and his power and his alterations.

How wrong I was. Now I can only recite my tale as I feel the last shards of my sanity leave me. As I feel him beginning to take over.

I'll add tags/characters later depending on what I plan for this.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

While most humans are brought to Equestria through near-death, death, or shenanigans, some are brought with a purpose. Meet Zack, he’s young, capable, more or less polite, and our victim. Princess Luna requires a moment’s peace, free from her sister’s pranks. One night, Luna comes up with the perfect plan: playing matchmaker. With her sister plotting, Celestia peacefully slumbers with dreams of mischief ripe in her head. If only she knew just what her little sister was capable of…

It has been several months since the disappearance of Twilight Sparkle..

One night, after watching her sister raise the Moon and set the heavens alight, Princess Celestia begins to bed down for the night, only to be interrupted by portal forming in her room. From out of the portal comes none other than Twilight Sparkle, garbed in strange armor.

Princess Celestia, along with Luna, Cadence, and Shining Armor, are overjoyed by the Element of Magic's return, but are justifiably curious as to where she had been and what she had been doing. And so, Twilight begins her tale. A tale of survival against impossible odds. A tale of a people fighting for the most basic right of all sentient beings. The right to exist.

DARPA, the Pentagon's team of mad scientists, have cooked up something interesting. A portal to another dimension? Why? Better question- why not? Somehow sensing a military application from this, generals from around the world cobble together a task force to go investigate this new land and mark sites for later exploitation. Backed up by the fury of the world's modern military forces, they launch their operation into this strange realm. When they discover a bright, happy universe full of talking ponies, they realize the folly of what their mission is. How will Equestria react to people whose confessed profession is being expert fighters? Matter of fact, how will Equestria react to PEOPLE?

Spartan A-042 finds himself on a mission gone wrong when he winds up in a land of talking ponies and other magical creatures as he struggles to comprehend how he got there, why he is there and above all, how can he leave.

Gerald McCormack, a 22 year old college student that is living by himself with his trusty butler, Gordon. When he stumbles upon a strange majestic-like woman in his own obstacle course--with a pair of Double D's I might add--he takes the woman in, and realizes she strongly resembles Princess Celestia! Will she be able to handle the human world that is so different from Equestria's? Or will she go into a paranoia freak out and Gerald would be forced to kick her out since she seems to be a crazed drug-addict hippy!?

LET'S FIND OUT!
