The Green Lantern Corps. Protectors of The Universe, led by the ancient Guardians of Oa, these peacekeeping soldiers protect nearly every sector of the universe with one sole weapon: the Green Lantern Ring. But not all of the universe is under protection; there remain several patches of space unprotected by Guardian influence. In one of these Sovereign Systems rests a particular planet, Pax Harmonia, full of many creatures and governments; the most notable being the Kingdom of Equestria.

When a sole Guardian appears before the rulers of Equestria, Princesses Celestia & Luna, and asks for a favor from old acquaintences, the peaceful country will be forced to deal with the concequences of letting a creature out of myth twice fold live amongst them: not only a Green Lantern... but a human. A young, cocky human named Hal Jordan...

Twilight Sparkle presents a collection of interviews, letters, essays, poetry and prose compiled over several years of her relationship with the human Bellerophon and his "herd", covering subjects as broad as Equestrian social taboos, comparisons of earth and Equestrian mythology, romance and the occasional recipe. Compiled by Twilight Sparkle, with foreword by Her Royal Highness, Princess Celestia.

(This is a bit of an experiment based on the worldbuilding concepts presented in AnonAuthor's Xenophilia [[NSFW] - caveat lector!], which intrigued me enough to want to take a closer look. It's likely you'll be very confused by this unless you read at least some of Xenophilia. Updates will appear as and when an idea pops into my head for a thing to add. And fair warning, some of this might come across very dry and dusty. Thank you academia! And thank you AnonAuthor for letting me have a go, and both AnonAuthor and AnonponyDASHIE for all the collab work they're doing. I'll make up for the dust by tossing in the odd piece of art now and then.)

[Part Two of the Riflepony Series] Braeburn was once a simple, humble farmer; not the type of pony one would look at twice. But a little over a year ago, all of that changed. Before then, he hadn't met the pony of his dreams. Before then, he hadn't discovered his lineage and new-found talent. Before then, he hadn't been prepared for the adventure that he was about to embark on. Now all the cards are on the table, and not just his life. Join Braeburn and Daring Do in this high-action installment of the Riflepony Series as they struggle with not only a new quest, but with fate as well. Old enemies have returned, and have formed a fearsome alliance. In the midst of chaos and absolute danger, Braeburn might have to break his one and only rule, as the new Colt of the West.

This is a story about Nightmare Moon mooning ponies in Ponyville one night. Things quickly get out of hoof as the evening progresses.

Another day in boring old Ponyville. AJ is out of town, Twilight is busy with her library and so Rainbow Dash is bored to death. As if fortune calls, a well known mare shows up.

This is just a short story about a little adventure of Rainbow Dash and Daring Do.

The planet destroyed. The flood gone and the covenant obliterated.
All because of one man, Sergeant J. Forge. The man who literally stared death in the face to save those aboard the 'Spirit of Fire'.
But what if the detonation of the slipspace drive tore a larger than intended hole in the fabric of space, essentially creating a portal to another world.
What if Forge hadn't perished on that day, but awoke to find himself in a completely new and foreign world ?

This story is a sequel to Austraeoh

Bellesmith is a pony who must perform experiments in order to keep herself and her beloved safe.

Rainbow Dash continues to fly east.

Equestria has made the discovery of the century. They found what they believed to be the last of the mythical race of the humans trapped inside of a large crystal. Curiosity takes hold and with the help of Twilight Sparkle and the elements of harmony they decide to set it free. But was that a wise decision?

Cover art not done by me.

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!
