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.

Changelings and ponies had always been natural enemies of each other, especially with the crystal ponies when they were around. Why wouldn't they be? Changelings were like parasites, feeding off the love that ponies gave off and driving them to illness.

However, Changelings had begun to decline. What started out with as seven hives have diminished down into three, all of which had gone into hiding so well that most ponies didn't know what changelings even were. Even Celestia had not seen one for quite a while, a long feat for an immortal pony.

Until she found a nymph. A new Changeling Queen.

Unable to find it within herself to abandon the changeling, Celestia ends up taking the nymph back to Canterlot under guise as Twilight Sparkle. The plan was simple; find the hive that Twilight belonged to and return her back to be raised with her race.

Of course, despite everything she learned through her long life, she had forgotten that things were never that simple.

For starters, she did not anticipate herself to grow fond of Twilight as time began to pass, or to beam in happiness when Twilight began to refer to her as mom.

What started as a normal friendly visit ends up taking two ponies on a trip down memory lane that leads them both to realize their friendship began even before Rainbow Dash's first sonic rainboom.

Twilight's still getting used to her new wings. She feels the need to ask somepony for flying lessons. And who better to ask than Fluttershy? If you ask Fluttershy, there's plenty of better ponies to ask.

Written for One-Shotober.

Twilight had always been a diligent researcher. She would routinely pour over every book she had at her disposal in preparation for every royal assignment. Except, sometimes books can only teach one so much. With this heretical idea in mind, Fluttershy and Rainbow Dash decide to take it upon themselves to make sure Twilight keeps her wings clean, and doesn't embarrass herself in the sky.

Applejack's got a secret she'd kept hidden for many years. Nopony would ever have guessed what she and Twilight were up to in the library late at night, once Spike had gone to sleep. That is, until a jealous Rainbow Dash decided it was her business to find out just what in the hay was going on.

I somehow ended up in the past. I'm not sure how far back I am, but I do know this was even before Celestia. This is much less peaceful and kind then back home, and I will have to be careful. This is much different then I thought, and I will have to survive this Equestria if I want to get home alive. Maybe Celestia can get me back to the right time. This doesn't even look like Equestria, I wonder how far I went back. I need to keep my identity as an alicorn hidden for now, and see what this world is like.
