Luna and I fly over the city and use our magic to try and pinpoint the elements location, I locate them just outside the city near the main gate of the mountain. "Sister, we have located them, we shall retrieve them whilst thou retrieves thy student!" I tell her getting a meek nod in return. "Thou knowest this to be right, sister. Should the Element Bearers perish, Equestria shall be vulnerable."

"We know, but we still think that there is a better way..." she replies and takes off towards Celestia's school.

I turn back to the location of the Elements and start flying over to them and conjure two swords made from my alicorn magic. After a minute of flight some pegasi guards intercept me and I frown in determination.

"Forgive us," I mutter and increase my speed catching the guards off guard and slice through one of them cleanly. Her lower half falls to the city below along with her intestines while she continues to hover for a few seconds staring at her missing half before dropping out of the sky as well.

"Damn you, Nightmare Moon!" a stallion yells before thrusting a spear at me.

The use of that name I hate so much makes me growl viciously and roar out in anger, I teleport behind the guard responsible and impale him in the back six times before decapitating him. "Never call us by that name again! We art Selene Nocturne!" I yell out and start blasting each guard with a mix of alicorn and demonic magic around me.

Body parts get blown off in my rage as the guards drop from the sky one after the other with panicked screams from the ponies below as the gore splatters around them, I then send out a sphere of magic around me pushing the remaining ten guards away from me and bolt towards the Elements as they may execute them in panic.

I see the carriage carrying them and land heavily on the unicorn guard to the right, killing him instantly following it up with a lunge with both my swords into the two pulling the carriage.

The last two guards draw their weapons but I don't give them a chance as I blast each of them with a beam of magic each, vaporising their heads off.

I catch the carriage with my magic before it could roll down the steep road, I then open the door and gasp at the condition the mares are in.

Rarity's horn has three inhibitors fused into it, Rainbow Dash has had her wings plucked of every feather with a lifeless expression on her face, Pinkie Pie's arm's have been broken and tied behind her with her hair straight and dull while Applejack has had both her legs broken. All of them have been tied up tightly as well. Spike has a muzzle over his mouth and a collar with needles almost piercing his now scaleless neck as well as chains tying up his arms and legs.

"By the moon, what have they done to thee..." I mutter and they all glance at me, each with defeated expressions.

"Luna?" Pinkie Pie asks weakly.

"Nay, tis us, Selene. Luna, Damien, Desire, and us hast come to rescue thee after receiving Spike's letter," I reply and use my magic to remove their bindings.

"What's the use... I'll never fly again..." Rainbow Dash says emotionlessly as her featherless wings wrap around her where she hugs them before breaking down into tears.

Pinkies arms are limp at her sides with a pained expression on her face, while Rarity can no longer use her magic as removing the rings will cost her her horn.

"How could the Princess do this ta us?" Applejack asks trying not to move her legs.

"Our sister is not sound of mind right now, she is being manipulated by a demonlord named Tirek we battled millennia ago. She believes ye art tainted by demonic magic and needed to be purged, so we hast come to take thee back with us," I reply and close the door. "Brace thyselves, we art heading to the Castle and shall await for Damien and our sister Luna to arrive with her student," I tell them and levitate the carriage off the ground.

More guards start to arrive so I stand on the carriage and use my left hand to focus on the levitation spell while using my right to blast the guards with beams and bolts.

'We need to get them to Damien, only he can restore them to full health,' I think to myself and head back to the courtyard.

I fly over to my sister's school but stop as a few pegasi guards fly up to block me.

"Let us pass, we just wish to collect our student without bloodshed," I tell them but they all frown at me.

"You shall not harm the foals, Nightmare Moon!" a mare wielding a bow states making me wince at the name and shoots an arrow at me, I use my magic to catch the arrow and snap it in two.

"Please, we dost nary wish to fight," I plead with them but my plea fall on deaf ears.

Four guards charge at me and I frown sadly. 'Remember, tis to aid our sister,' I tell myself and teleport behind the mare and grab her in my magic and knock her out. "Sorry," I tell her and cast a slow fall spell on her making her drift slowly to the ground.

I flap my wings to avoid being run through by a spear and cast a concussive blast of magic to knock the stallion out and then cast a slow fall spell on him.

I repeat this for the last seven guards but slap myself for my stupidity. 'We canst just teleport to the school,' I tell myself and teleport to Dusk's room.

I spot the colt sitting on his bed crying with what appears to be magical bindings around his arms and legs, his inhibitor ring has also now been fused into his horn. I frown sadly at the colt as he's done nothing to deserve this.

"Young, Dusk. We hast come to rescue thee," I tell him getting his attention.

"W-Who are you?" he asks me fearfully.

"Tis I, Princess Luna. We've come to take thee away from here before our sister does something she'll regret," I reply and quickly remove his bindings.

"Princess? W-What happened to you?" he asks looking at my draconic like wings.

"We've been infused with demonic energy to restore our lost power, remember the two demons thou summoned?" I ask him and he nodded. "They art here to rescue some friends and we've come for thee," I tell him and pick him up.

He starts crying again and hugs me. "I thought you left me here... Just like everypony else," he tells me, which makes me hug him as well.

"We wouldst never abandon our student, tis just our sister is losing herself to the influence of another. Hopefully Sir Damien canst make her see reason," I reply and teleport us to our other half.

Once my vision returns, I'm sitting in a carriage with the Elements but gasp as I see their condition. "By our stars, what has happened!?" I ask them.

"Selene? I thought you were outside?" Pinkie asks me as I can hear the sound of magical blasts outside.

"Tis us, Luna. Our sister is outside correct?" I ask them and they nodded. I hand the colt to Rarity to look after. "Please keep our student safe whilst we aid our sister," I ask her.

"Very well, Princess," she replies and sets the colt onto her lap.

I open the door and fly out and join my sister on the roof. "Sister! We hast retrieved our student, make haste to the courtyard, we shall erect a shield to protect us!" I call out to her and she nodded as I cast a powerful shield around us. Selene levitates us to the courtyard where the sounds of an intense battle within the Castle can be heard.

I cleave through two guards and use my darkfire to blow down the main door of the Castle. Once that's done, Desire and I rush past the guards and into the Castle proper, I can feel Celestia's power just ahead of us.

"Desire, I'll deal with Celestia while you seal off the room and deal with any guards who get in our way," I tell her.

"Okay," she replies and again I blow the doors leading to her royal highness down.

I can see her sitting on a throne with a surprised expression on her face. "YOU! How did you get here undetected! I would have sensed a foul demon like you coming from a mile away!" Celestia yells in anger upon seeing me.

"You don't need to know that, I did warn you what I would do should you continue to attack us," I reply and take on my demonic form.

Celestia actually growls at me and summons a large greatsword made of silver along with silver armour as well. I use my improved speed to appear in front of a guard and headbutt him hard, knocking him out while I claim his sword and shield and turn back to face Celestia.

"You dare harm my ponies in front of me again!?" she roars out and charges at me.

"That's rich considering you were planning to kill your own people due to your paranoia," I reply and block her swing.

I grunt as she's hitting a lot harder than the last time I fought her, I retaliate with a thrust of my longsword which is deflected by her armour.

"I'm prepared for you this time, demon," she tells me and swings her sword again, I block it but get sent back stumbling a few metres.

'Dammit, at this rate I'll have to use my souls to get stronger,' I think to myself.

'Master, if you use the soul of Val'hades, we'd be strong enough to resist even the silver of her weapons and armour for a few minutes, but this will burn up the strongest soul we have,' Thanatos tells me.

I frown as I block another heavy hit from Celestia. 'Do it!' I tell him.

I roar out and feel a burst of power and energy flow through me as Val'hade's power courses through my veins. My purple skin is replaced by darkfire and my hair starts whipping around as if I was standing in a tornado, a third pair of shadow wings bursts out below the second and another pair of shadow horns grow out the sides of my head like a rams. My eyes then turn completely red and my teeth lengthen as well.

My vision is sharper and my hearing is exceptional, I feel stronger, faster, and the world around me seems to have slowed down a bit. Although I can feel the power slowly waning so I have to be quick about this.

"Let me show you why I am the Overlord of Tartarus!" I yell out at Celestia.

I burst forward and summon Thanatos to my right hand, once in range, I swing forcing Celestia to lean out of the way, but my blade clips her chestplate and rips a large tear into it. I hear Thanatos grunt but quickly recover as I swing again tearing off her left pauldron.

"Impossible!" she yells stunned that my weapon is affecting her armour.

I ignore her and swing again slicing her sword in half, silver may be a demon's weakness, but it's still not as strong as my scythe.

Twisting my body I slice off her left forearm protector which also just cuts her arm, she hisses in pain and fires a blast of magic at me, I deflect it with Thanatos and tackle her into her throne which bends backwards from the force. I grip her neck and toss her into the far wall and then dash towards her while carving off her armour.

She hates us demons so much? Then I'll just turn her into one once I've removed all the silver from her! Maybe that will remove Tirek's influence and I can use the Tartarus Gate here to get home.

She still has her boots and leggings on which I start slicing apart, she's covered in cuts but those will heal once I turn her into a demon.

I'm tackled away by a guard who then screams as the darkfire covering me engulfs him and turns him into ash quickly. I get up to see Celestia stumble out of the hole in the wall as pieces of her armour fall off leaving her in tattered clothing exposing parts of her chest.

"And where do you think you're going!?" I ask her and dash towards her.

Her eyes widen and I see her horn glow which I quickly grip with my left hand and she screams in pain as her horn begins to melt, I then cut it off at the base with Thanatos cutting her off from her magic.

I then tear off the last of her silver armour and then wrap my arms around her body, fear is in her eyes as she looks into mine. I then open my mouth and sink my inch long teeth into her neck.

Her screams amplify as I pour a heavy amount of demonic energy into her, her feathers fall out and turn to ash as membranes grow in their place. Her mane and tail change from an aurora colouring into blazing infernos like flares from the sun itself. Her missing horn regrows and bends upwards to give it a slight curve and a lethal looking tip.

Her muscles are now more defined and her hips and chest expand an inch, teeth like a human’s replace her flat ones and her eyes turn orange and slitted. I then add commands making her one of my loyal demons, as a precautionary measure while overwriting Tirek's.

I release her and she drops to the ground unconscious with my mark now on her neck, I still feel power flowing through me and look back to Desire. An idea comes to mind, instead of wasting the rest of this energy I'll give it to Desire and turn her from an archdemon into a demonlord as well.

"Damien?" she asks me cautiously.

"Prepare yourself, my dear," I tell her and open my mouth as I walk over to her.

Her eyes widen and a smile forms on her face as she figures out what I want to do. She leans her head to the side as she drops the corpse of the last guard in the room and pulls her hair away.

I wrap my six wings around her and bite down into her neck. She hisses in pain but moans as well as I flood her full of the remaining energy.

Her horns move down her forehead and fuse together before lengthening and curling slightly back. Her wings grow larger and her tail shrinks down and hair grows out of the stump into a dark blue tail. Her muscles also get more defined as the change finishes.

I release her and look her over as I'm now back to my normal demonic form. She looks just like an alicorn demon now. I may have lost the strongest soul I had, but I've gained a stronger wife and now a new alicorn demon in my ranks.

"Ohhhh, I feel so gooooood~, so powerful!" she says and kisses me roughly.

"Good, grab Celestia and let's go," I tell her.

"Grab her? We taking this skank back with us?" she asks me incredulously.

"She's now under my influence, so now she'll see reason and stop acting like a paranoid bitch," I reply and head towards the door with Thanatos in hand. I watch as Castle staff run around in a panic.

Desire grumbles and hoists Celestia over her shoulder before following me out the courtyard where I see Luna and Selene casting a shield over a carriage as some guards are attacking them. I guess the Elements, Spike, and Luna's student are in it.

"Luna! Selene! Prepare the teleport spell!" I call out to them and they look towards me as well as the twenty-four guards trying to break down the shield.

"Sister!" Luna calls out seeing Celestia's unconscious body.

"She's alive, now get the spell ready!" I tell them as both Desire and I slip through the shield and Desire takes over maintaining it.

"Halt! Release the Princess demons!" a guard yells at us which we ignore.

Luna and Selene place their hands onto the carriage and after a few seconds of charging up the spell with the aid of my energy, we teleport back to Skullcove Bay.

Luna and Selene fall to their knees panting for breath as I look around and see we're in front of the king's ship. Many demons look at us in surprise but Twilight and Fluttershy rush out of the ship and Twilight gasps at seeing Celestia.

"Oh my gosh! What happened!?" she demands and flies up and checks her mentor over.

"I did what was the most logical choice, I turned her into a demon and in doing so, removed Tirek's influence," I reply and jump off the carriage and open its door, Only to frown at the state the girls are in.

Rainbow glances at me and then scowls. "YOU! THIS IS ALL YOUR FAULT!" she yells at me and tries to punch me. I don't make any attempt to avoid it as she continuously punches my face. "IF YOU NEVER SHOWED UP THEN WE WOULDN'T BE IN THIS MESS!" she continues yelling before she gets tired and slumps to the floor of the carriage.

"Oh? I never asked to be dragged here," I reply and grip her by her throat and pull her out of the carriage.

"Hey! Don't ya go an' hurt her!" Applejack tells me which I ignore.

I twist Rainbow's head aside and without warning bite her neck making her yelp and try to struggle out of my grip. Membranes grow on her featherless wings and tufts of fur grow out of the tips of her ears, her eyes turn red and slitted and a pair of fangs grow in her mouth. She's now a lesser demon thestral for now.

"There, you have your wings back," I tell the rainbow haired girl and drop her onto the ground.

She grunts in pain and I look at the others. "If you want your wounds healed you'll have to become demons as well," I tell the other three before a little purple and green lizard jumps out of the carriage.

"Twilight!?" he says looking around.

"SPIKE!" Twilight yells and flies down before engulfing the lizard in a tight hug. "Oh, Spike. I missed you so much!" she says and sniffles as she continues to hug him.

"Twilight? What happened to you!?" Spike's asks, his question muffled by Twilight's chest.

She pulls back and while she explains what happened to her, I look back to the other girls. "Well? Do you want to be healed or not?" I ask them, I turned Rainbow instantly because she was pissing me off, I'm giving these girls a choice.

"And be a big meanie like you? No thanks," Pinkie replies with a frown on her face.

Twilight gets up and walks over to the carriage door and gasps. "Oh girls, what happened to you all?" she asks seeing their condition.

"Twilight!" they reply as she steps in and sits down.

"What did you do to me!" Rainbow demands and stands up with a glare on her face.

"I gave you your ability to fly back," I reply coldly and point to her new wings.

She looks back and goes wide eyed at the bat like wings. "Rainbow? Are you okay?" Fluttershy asks her.

Rainbow turns to see her and quickly hugs her. "Shy! We were so worried about you! We heard what happened at your home only to find... well..." she replies and frowns sadly.

"I know..." the timid thestral says as Angel walks over and stands beside her along with a demonic bear which has bone plates over its body like Angel and two demonic nine tailed foxes. I think I'll call them ursinos and kyuubi.

Rainbow then spots them and yelps. "Whoa! What are they!?" she asks and backs away. I notice Angel smirking at her.

"Oh, this is Angel, you remember Angel right?" Fluttershy says pointing to the hellhare.

"Wait... that's Angel? The cute little white fluffy bunny menace?" Rainbow asks while staring at the hellhare.

"I ain't cute and fluffy!" Angel replies making Rainbow yelp and hide behind Fluttershy. I like how he didn’t deny the menace remark.

I chuckle and turn back to the others who are still talking to Twilight. 'This is going to be a long day,' I think to myself.

So? Should Damien turn the other girls? And what would a demonic dragon look like?

Also how will Celestia react when she wakes up?

Tune in next time for anoth...
