Oh, Equestria! Oh, the Light of Harmony…
The greatest land where ponies have lived and thrived for centuries under the warming rays of Celestia's sun. They welcomed each new day with joy, forged friendships, and shared love. And they believed it was unshakable.
Everything changed when a cosmic body crashed onto Appleloosa, bearing death itself in the form of a green crystal. Barely had Equestria recovered from the Storm King's invasion, but it was as if the sky itself had unleashed its fury upon the ponies by some unknown fate. A town in the desert perished, and the green crystal took root. It infected the land, twisted the plants, and destroyed all living things.
The unprecedented disaster that engulfed the entire country alarmed the alicorn sisters like nothing else in their incredibly long lives, and Twilight Sparkle threw all her might into finding a way to eradicate the green plague. But it was only the beginning of great sorrow.
Looking up at the stars, nopony could have imagined that somewhere in their depths a darkness blacker than the night had been spreading since time immemorial. Demons from bygone eras, they had long roamed the cosmos, savoring death and asserting it wherever life was encountered. Their tentacles wrapped around the very fabric of creation. And now, having already conquered a fragment of the Universe known as Earth, they extended the shadow of their relentless darkness to touch the world of the little ponies, preparing to subject it to every trial.
And they would watch coldly as the Fire of Harmony waned and dimmed!..

(Author's Note: This fanfic is a crossover between MLP: FiM and the Command and Conquer and Crysis game series, which are merged into a single universe with a shared timeline here. The plot takes place significantly after the conclusion of both of them.
In terms of FiM's chronology, the story of this fanfic starts in the following autumn after the Storm King's invasion of Canterlot, as depicted in My Little Pony: The Movie. Therefore, it's an alternate development of events in the eighth season, where the Pillars of Old Equestria were not returned to the present time.
This project is planned to be very extensive, so stock up on tea/coffee and cookies! Enjoy your reading!
