Tiberium. The infamous green crystal that destroys entire worlds in its wake of global proliferation. It has been a little over a century since the Tiberium threat was first wiped out on Earth, and with it, the primary vestiges of the Brotherhood of Nod. When the GDI advanced humanity to the stars, they found that Earth had not been the only target of the alien Scrin: dozens of other worlds had already been claimed by Tiberium, and the Scrin returned in full force, attacking human colonies across space, stopping human expansion. To fight back, the GDI undergoes a reformation to become the Interstellar Defense Intiative (ISDI) and enacts the Hallman Directive, designed to stop Tiberium spread wherever it may be; such a protocol brings the reincarnated ITC Methuselah to a planet being ravaged by the green crystal, and the forces under Commander Martin Alexandra deploy to stop the threat.

Eighty years after the events of The Dread Chitin, Equestria is a radically different place. The arcane science of the late Duran Thirk and the information found on the Star League library core have combined to catapult the nation's science ahead by hundreds of years.

Now, facing the possible aggression of a completely unknown alien power, Twilight Sparkle and her friends have to gather together once more, leading a crew of the best ponies they could assemble in a voyage outside their own star system. They seek to learn about their potential foe, to explore the galaxy around them, and possibly find allies and friends to stand alongside them. Who knows what they will actually find?

Shawn Spencer, psychic detective, is a thick-tufted boy genius who ice skates through life on polished blades of snarky eloquence. He has tested himself against some of the greatest criminal minds of his time and emerged victorious... though often through unbelievable luck and not a small amount of bumbling.

Now, he faces a challenge unlike any before. One that will test his mind, his sanity, and his adaptability as he is thrust into the midst of an unfamiliar world and the ponies who populate it.

The Mane 6 face their own challenge, as an old enemy, tempered in the crimes of a much harsher world than theirs, returns to Equestria. It is a challenge they are ill-prepared for and one that only their strange, new, alien friend can help them overcome.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

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?

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.

A young man lost in the hilly embrace of a mountain sleeps the night away under a knot of tree roots. When he wakes he will find himself thrust into a strange new environment, the Everfree Forest. With only his pack and his experience as a Boy Scout to aid him, he must survive, make sense of his surroundings and with some luck, ultimately find his way home. What does one do after wandering beyond the edge of the map? And better yet...

What if you are not alone?

I have been reading fan fiction here for a while and wanted to give something back.
My first fiction ever so constructive criticism is welcome. Fair warning, it takes a while for me to write a chapter so expect gaps between updates.

[Hiatus notice: As of 10/1/2022 this fiction is on hiatus so I may focus on other projects and items, will resume at a later date.]

Rated teen for strong language

Awesome cover art by Carnelian. Seriously, the guy has major skills with how fast he drew this up.

and of course ALL CHARACTERS / REFERENCES BELONG TO THEIR RESPECTIVE OWNERS. “MY LITTLE PONY FRIENDSHIP IS MAGIC” IS OWNED BY HASBRO

NO PROFIT WAS MADE IN THE CREATION / DISTRIBUTION PLEASE DONT SUE ME OR ANY PARTY THAT DISTRIBUTES THIS WORK (unless they try to sell it, then by all means go nuts)

A call for help from Cherry Jubilee brings Applejack back to a very different Dodge Junction. Its residents are fearful, a gang of kleptomaniacs has the full run, trolls are on the loose, and the sheriff's in a criminal's pocket.

Besides Big Macintosh, the only pony on Applejack's side is the most accident-prone being in Equestria. If the schemes of a psychotic but dainty griffon don't ruin things, Clutterstep just might. Applejack reckons they've got as much chance as a seed in a storm, but an Apple always honors her friends. It's a race to finish the harvest and save Cherry Hill Ranch while making it out alive back to Ponyville.

King Sombra’s dark influence was obliterated by the Crystal Heart, and the villain is well and truly dead. But when he attempts to steal the afterlife of an innocent victim, a human spirit is left hurtling towards Equestria, where this unfortunate soul is revived into the only vessel available: the reconstituted body of King Sombra himself.

Thus, a cheerfully oblivious alien is crammed into the form of the most evil and malicious being Equestria has ever known. Not that Shining Armor and Cadence know this, of course. As far as they are concerned, the King is back and he’s lost his fricking mind.
