Shadow of Equestria

When I arrive back in town I give a loud yawn, and walk into the library when I see Twilight smiling happily at me. " Did you guys find the cave?" I ask very curious.

" See for yourself." She says before gesturing to a cloth on the table behind her. I walk over, and upon taking off the cloth see a beautifully dark crystal looking back at me. I touch it with my hooves, and it dissolves into a liquid that covers me.

"AGH!" Is all I can yell before I sink into the ground, and land in a room with a figure of pure evil staring at me. The smell of evil fills my nose as I pick myself up in the shadow crystal cavern. His green eyes shine with malice as he looks at me, and seemingly into my soul.

" Looks like someone got himself into trouble." He says deeply as the tugging comes back, but stronger. It was almost like.........something I had taken complete control over. The part of my soul, and sanity the Shadow Demon in me possessed. He was giving it equal control again.

" YOU BASTARD!" I yell before my iris begins to glow bright red, and I am pushed back into the darkness of my mind, as the demon in me snaps my sanity in half. I come back out of the floor of the library with my irises looking brown again.

" What in the hay happened down there?" Applejack asked worried with the rest of the mane six nodding in agreement.

"shia edhiao hdioa axahiond dida dhioah hoaih aoh daoh doah eioh eidhaiobceO" I begin chanting in an evil demonic voice. The mane six just go wide eyed before rushing towards the chest with the elements of harmony in them. The shadows grow longer, and longer, and longer until the light is no longer coming through the windows leaving the void outside. I turn into my shadow form before melting into the darkness before a suprised mane six run out with the elements on them. I decide to torture them one by one before sucking out their souls. I slink through the shadows waiting for one of them to separate from the group so I can begin. Fluttershy looks around scared before running into the closet and curling into a ball. I invisibly slam the door shut, and the others try to open it to no avail.

" Fluttershy. Do you want to see something?" I say sadisticly with my demonic voice.

" No please. Go away." She chokes out crying her heart out from being so scared. Being slightly mad I grab her head pulling it up, and look into her eyes. She tries several attempts to close them without success. Instead of sucking her soul  push into her head causing her eyes to roll back as I begin the torture. I enter the dark realm that I put in her head as the scene plays out. Twilight goes to sleep, and wakes up in a diaper in front of Fluttershy.

" Fluttershy? What's going on?" She asks a little afraid from what I can tell from her voice. Twilight attempts to move, but finds her muscles useless.

" I've always wanted a baby Twilight. You are the perfect one." She says with a smile. The rest of Patty Cakes plays out like every other spinoff does with Twilight's head going completely baby. I release Fluttershy, and she falls over eyes now black with my evil face seen visible laughing. The door finally opens, and they run in to see my handiwork.

" Oh Celestia." Rarity says staring down at Fluttershy. Then something I forgot to think about happens. Twilight uses that same memory spell trick that worked on the Discord Crisis( As I call it). Fluttershy shakes a bit but her eyes go back to normal. They turn to see me with a gutted Spike, Owlicious, Sweetie Belle, Applebloom, Scootaloo, Angel Bunny, and Winona. They shake as my plan works. The dark magic I used takes effect as they all fall down to the spell. The incantation deactivates, and the light comes back allowing Spike to run in seeing my handiwork.

"Sweet Celestia..." He says surprised running out quickly. I decide to not let Spike escape, I'd deal with the useless ones later. Quickly slinking through the shadows I follow after him, before falling to the floor hissing as it somehow got brighter. Celestia landing down, and picking me up. "Sombra..." She mutters before light purges through me. I fall to the floor normal again coughing in pain. The tugging going away. "H-Holy shit." I says still a bit dazed from what happened. Great now IT was back. Well least I was okay for the time being. The Mane Six finding themselves finally waking up.
