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.

It's strange how a short few years can seem like such a long time ago, Twilight remembers the moment she was told the truth about her, and how she would outlive all her friends.

When Sgt Castle drops into strange new land, he has to cope with both his nightmarish past that had followed him to this peaceful land, and his uncertain future as he finds himself developing new friendships. All he truly wants is to return home, but is that the best option, or is it not even an option at all?

Twilight Sparkle always knew she was different from other ponies. How will her friends react when they find out the most magical unicorn in all Equestria isn't even a pony?

Now with TV Tropes!

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 year is 2414. The Federation is alive and well. The Klingons back to being the Federation’s Allies, the Romulans power diminished, the Undine now an Ally, and the Borg all but washed up. And by now the Zeta Andromeda Galaxy had moved close enough to the Milky Way to allow a Transwarp Gate connection. Starfleet has jumped on the chance and is now exploring the new Quadrant. Leading the charge is the Temporary Federation Flagship U.S.S. Evans-A, veteran of the Klingon-Federation War, the Borg’s invasion of the Alpha Quadrant, and the Romulan-Reman Civil War with Vice Admiral Blaze Johnson at the helm, the man who destroyed the Borg H.I.V.E.
Arriving at an uncharted system, Blaze and his loyal crew find a mystery. A planet that is the center of its system, surrounded by Spatial anomalies, and the primary species are Ponies? Defying the Prime Directive, Blaze goes and explores the planet. But there is more on the planet than its ultra friendly inhabitants. What he finds there could threaten not only the planet called Equestria, but the Federation, and both the Milky and Zeta Andromeda Galaxy.

After destroying the Star-Forge, and narrowly escaping after killing his former apprentice Darth Malak, Revan spends a number of years exploring the empty reaches of the galaxy.

Crossover with Star Wars KOTOR. In the new, re-edited version, it is now incorporated into the aftermath of KOTOR, when Revan leaves to explore the galaxy alone.

Looking for someone to draw me some cover art.
