Two years ago Dr. Lorenzo Faust, a renowned American physicist, discovered a way to travel to alternate dimensions and stumbled upon the land of Equestria during his research. Within the span of a year two facilities were constructed - one on Earth and one in Equestria - to establish a bridge between the two worlds and allow the inhabitants to cross over into each others lands. Princess Twilight Sparkle is charged by Princess Celestia to serve as the Equestrian ambassador as well as judicial liaison on Earth. She asks her friends to come with her to help accomplish their greatest task: to save Planet Earth, starting with the American people. But can a world plagued with millions of sick and distressed animals, savage new weather patterns, and severe shortages of clothing, food and happiness be saved by six ponies?

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

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

A Soot-Covered World, book 1.

Luna and Pipsqueak have known each other since that Nightmare Night, but finally they are going or a grand adventure together! A trek across Equestria to find the legendary Nessie! Along the way, they will encounter strange creatures of old, and find the truth behind what happened to Luna's friend.

While they are gone, a prank war is brewing in the castle. Private Blitzen and Sergeant Feather Fury are tasked with a special mission: Prank the Sun Princess and do NOT get caught!

Two stories for the price of one. There are a few sad scenes, enough to warrant a slight warning, but I am mainly focusing on the Adventure in Story One, and Comedy in Story Two.

Note: Story Two is not necessary to read, as it mainly involves OCs, but does give a bit of side story on what happened while the Princess of the Night was away!

Reader, in ancient days, the old lords of the world numbered in thousands. Then hundreds. Then even less.
Now, they are found only in tapestries and fanciful ballads.
The creatures are all vanished. All but one.

Rumors say there are more of him, somewhere far away. A young and supposedly gifted mage called Star Swirl, and Heartstrings, a gentle spinster, have joined him on a journey to find the rest.
