Final Crisis of Equestria

The Nightmare essence was banished once again, the radiant friendship of Twilight's new friends escorted the malicious intent to banishment on the moon like it had spent the last thousand years. But without a host, the evil would not be contained. And so it passed through the ether of godspace until it looped around and, roughly on month later, it found a willing host.

Trixie's eyes glowed with hatred, she now had the willpower to act upon her grudges and express her resentments with the suffering of a kingdom.

Pinkie Pie had a premonition stronger than she's ever had before, her cutie mark vanished with the last vesige of sanity. To fill the gap where her mind was, she adopted belief in Anti-Life.

Nobody knew the specifics of how it was happening, but by the time the astonomers had discovered that Celestia and Luna were banished to the moon, it was too late.

Gilda grabbed a bullhorn and addressed Equestria, Trixie silently standing behind her. Gilda's shouting would represent the start of the Darkest Hour.

"I know you think this gathering might be foalish, you might be eager to leave your grudges behind. But Poniville is no longer going to be the center of the world, it will be the end of it. Your new brand: Friendship is Anti-life. This isn't a twilight of the gods... there won't be Twilight Or Gods or anything but chaos and pain and those ponies will be put into their place. WELCOME TO MY NIGHTMARE."

Hoity Toity, Photo finish, and Fancy Pants all indulged in a new level of hedonism. Silver Spoon and Diamond Tiara followed Filthy Rich into a lifestyle of decadent hatred. Their new ideal: "Evil is fashionable"

Green Apple Acres was suddenly a place of rotten flora. Big Mac poured our delicious cider to create a new kind of Apple Juice which would only barely nourish the drinker's lives. Flim and Flam also contributed to the intentional removal of flavor from the nations resevoirs. A confused Applebloom saw the way the adults were acting and gave up hope on her family, instead running to find help elsewhere.

Cheerilee was with her students when Applebloom joined them. She took the students underground to caves she imagined would be safer from the atmospheric effect. "These caverns go underneath all of Equestria, here we'll be protected from whatever is contaminating the sky."

But soon as the teacher and her students throught they were safe, Applebloom understoof the true nature of the sickness."You don't get it, this isn't a weather condition, it's an uprising. Our crusade is over, there will be no more cutie marks. We don't need our flanks to be marked when our souls become marked by the will of Nightmare." And that is when the Diamond Dogs emerged from the shadows ready to enslave Cherilee's young students.

Cranky Pants was mostly unaffected.

In a custom-made costume, Rainbow Dash joined the team of Shadowbolts who were dragged stormclouds across the sky. "I'm here to join the Shadowbolts, if there's action, I want to be in front."

With no more ambient love in the universe, there was nothing for the Shapeshifter Horde to feed upon. So instead they fed on hate and found it just as nourishing.

Shapeshifters and Shadowbolts began the frontal assault on truth and love.
