There was no denying it now. Nothing would stop Twilight from consuming all in her path. She could feel it. It whispered to her of the horrors that would befall her homeland. It sang of the dirges of the dead and dying. She had lost all pretense of sanity awhile ago. Whatever she clung to now was an echo, a shell of what she used to be. Soon the Twilight Sparkle everypony knew and loved would be close to dead, consumed by the dark curse inflicted on her by her mistress Octavia Melody. Soon dead things would creep beneath the moonlight, and terrors to freeze a pony's soul would slither between the shadows, waiting to smother their victims in her name. Or better yet, in THEIR name. Three unholy beings would be summoned to Equestria and tear its foundations asunder.
The lands of Equestria would fall one by one to the 3 Lords of the Burning Hells. The Lord of Hatred would rekindle the bitterness and mistrust of the three pony tribes to an unbelievable level. And Princess Luna would again be torn between staying loyal to her sister, or being endowed with the power and title that would be offered to her by the Lord of Destruction himself, Baal.
She could feel the darkness calling out to others of its like across all dimensions. ITs taint left her wanting more power and depravity. The Darkness inside Twilight was about to bring forth the most unlikeliest of allies to her world. A trio that nearly destroyed a far away land with hellfire and creatures of your utmost nightmare. Out of the blackness of the shattered Soulstone emerged 3 beings, but the world they entered was not their own. Normally when demons are slain by mortals or the Angels of the high heavens they are reborn in the Burning Hells. But not these three. Their souls were dredged up and pulled from the abyss into a swirling portal not ment for them. Twilight Sparkle had unknowingly put all of Equestria at risk now.
Whether or not she could be saved was of no consequence at the moment. Equestria would be graced with the presence of Three of the most powerful Demon lords known to the far away land known only as Sanctuary. Matheal's death at the hands of the one called the Nephaelm had released Diablo's essence from its stone prison. And yet Tyrael had no way of knowing that this action would also create momentary contact with another realm none of them had ever heard of. This new land though would come to feel the fear, despair, and Terror that accompanied these three Strangers.
As they fell through the portal, the three brothers landed in an open field not far from Canterlot. The lands around them were pristine, the grass being touched by a slight breeze. As they got their bearings they all turned to one another and cracked a wicked smile. They weren't sure of what they would find in this new world called Equestria, but they knew they'd take advantage of the chance to corrupt this land to their whims. The Three had emerged.
Their names were Diablo, Mephisto, and the Lord of Destruction himself, BAAL.

Back in Ponyville
AJ hugged Sweetie Belle as tight as she could. The poor filly had been crying all night, since Applejack had told about what had happened to Rarity, but most of all that if they had gotten married that if anything had happened to one of them, the other was to take care of Rarity's little sister like family. Sweetie couldn't believe her big sister was just gone. How? How could Twilight of done something like that? she thought to herself. The two held onto one another until Sweetie had sobbed herself to sleep in AJ's hooves. Her and Applebloom had set up an extra bed in the Clubhouse for Sweetie to stay in. AJ still couldn't believe it herself. The one pony in the world that she loved more than anything was gone now, taken away from her by a friend that was herself possessed by a darkness none of them could comprehend. And that darkness would cover the land in misery soon enough if the Royal pony sisters didn't attempt to stop it.
Applejack just stared at a picture of Her and Rarity that was sitting on her nightstand. The picture showed the two mares in a loving embrace, with engagement rings around their hooves. It had been the happiest moment of her life right then and there. All Applejack had left now were memories of her lover. And those kinds of memories she would hold onto no matter what. She had to understand why Twilight did what she did, she just had to. Something though took ahold of her. An intense Hatred that she couldn't deny. IT creeped into her mind, whispered into her ears that she should find Twilight , and bury an axe in her former friend. AJ picked herself up and trotted over to the axe that was resting over the mantle of the fireplace. The axe in question had belonged to her father at one point and had been passed down to her after her parents deaths. She held it in her hooves as clearly as one would of held one in their hands if she had been human. She carried the axe in her mouth and closed the door behind her. With the hatred burning stronger now the closer she got to where she needed to go, the more her rage fueled her.
None of their other friends knew what she was planning, and even if they did realize what she had planned, none of them would stand in her way. Not even Rainbow Dash. Applejack was no longer an Element of Harmony, she became the embodiment of Hatred now because of what Twilight had done to Rarity. And she was going to make Twi suffer hard for it. She was going to make her understand the pain and suffering that AJ was going through now. The Element of Honesty was gone. And the Lord of Hatred would be the one to cast the first stone.
Mephisto had acquired his first pawn. Her name was Applejack.
