Chapter 1; Awakening

How long had it been? Since I had been sealed up by the Demons of Hell itself? I honestly didn’t know because the sarcophagus didn’t keep track of time! The last thing I remember before my burial and imprisonment was running blindly into the Demon’s Cathedral and being ready to slaughter every kind of Demon there, but alas, I had been tricked by those foul beasts! It lead to the Demons making the Cathedral literally fall directly on top of me, turning it into a supposedly eternal tomb. There were several unanswered questions to my predicament though, including who had the balls to free me of all people? ‘And why?’ My mind had so many questions! But above all of them, was one; ‘Where was the slaughter?’ I also, as I was awakening, remembered what the Seraphim had told me long ago; ‘They are rage, brutal, without mercy.’ They had said, talking about a few of the Demon’s traits. ‘But you... you will be worse. Rip and tear, until it is done.’ Upon the last words, my eyes finally opened after seemingly an eternity! My thousand year old eyes adjusted rapidly to the bright lights all around him, it was only then I remembered the chains that had been set upon me during my burial, Magic it would seem. I heard a noise to his right and saw a Demon, a Possessed Soldier, though I generally preferred the term Zombie, cause it was more accurate, stumble towards me slowly, as it drew closer, I angrily tugged harder than ever to try and get out, my wrist skyrocketed with pain in the very instance the chains were pulled taut, I ignored it however and just tugged harder, the Zombie was within biting distance when I finally broke the chain on my right arm. Using what little time I had, I threw a mighty backhand to the rotten bastard's face, breaking a few pieces of its skull off. I then grabbed its head and after holding it for a few seconds, the Zombies’ teeth gnashing wildly in an attempt to bite me, I smashed the head of the monster so hard into the sarcophagus’ side, it exploded in a shower of blood and brain matter. I only had one thing to say to everything and everyone who could hear me: “I’m back, and it’s time... TO RIP AND TEAR!!!!!!!!!!”

My voice was deep, gravelly and had such a, dare I say, badass tone to it that it just sounded cool. I then tore off the chains on my legs and remaining arm and I threw myself off the table. I landed gracefully on the left side of the room where coincidentally, a lone pistol, similar to the other two or four I had used so long ago, was sitting. Grinning madly at the notion of a brand new weapon, I picked it up and then at inhuman speed shot the other two Zombies in the head, making them fall to the floor, dead once more. I then examined the pistol I had found, it was actually far more advanced than anything I had ever encountered; its cartridge seemed to be missing and according to the manual I had then found on the table next to me, it needed no cartridge as it absorbed something called ‘Argent Plasma’. I admit, I was briefly baffled at the name, I had heard of Argent Energy, but not of Argent Plasma. Shaking my head, I decided to look into it later, because I had Demons to purge from this land. I pressed on a screen on a nearby wall and a hologram of sorts activated it seemed. I saw a woman walk through the door, almost as though she were a ghost, her entire body was riddled with cybernetics, intricately designed and crafted into her bode, also covering any... unnecessary bits... anyway, she walked up to what was once my prison which had a few people bowing to it, all holograms, and she spoke as she was right next to it. "We have to contain this..." she seemed to state as the hologram vanished. I sighed. "She is a fool... just like I was..." I said glumly, I then left the area as the door opened up and I walked through.

I then walked for a few minutes, killing Zombies left and right, bashing their heads in and shooting them up. After turning a corner later on, I came upon quite a welcome sight for my extremely sore eyes; my very own, and very robust, Praetor suit of armor, of which had been removed during my imprisonment. The green paint of the metallic alloy clashed quite badly with the blood red flesh of the seal around it. I smiled so wide that it I was surprised that I didn’t split my face open. I walked up to my grand armor and put it on one piece at a time. First I slipped the leg pieces on, then the boots, the arms were next, slipping on quite easily. The chest plate went on as a two pieced piece of the armor; one piece over the chest and the other on his back. Once it was over my chest I forced the two pieces together until I heard a soft ‘click’ locking the two pieces together. Lastly, I fit the large helmet over my equally large head as a HUD appeared in front of my vision, showing my health condition as well as my ammo count and armor meter. The armor then sealed itself to my skin, to prevent any sort of looseness. I then lifted my new pistol up into a ready position and continued towards another hallway on the right, my instincts ready to snap at the first sign of trouble.

I then later came upon a corpse of an elite soldier that hadn’t been possessed quite yet, his lower half was stuck in a door that wasn't properly closed, due to it probably being forced down onto his torso, however, when I saw what was in his hands, my eyes widened due to the weapon the soldier was holding; a gun it seemed. In extreme excitement, I ripped it right out of the corpses’ arms, inspecting it further, I found that it was a UAC standard issue Combat Shotgun, pump action and utilized the same warp technology as his new pistol. I loved these things, powerful and non ammo consuming, not just that, I looked like a badass while doing it. I pumped the pump and found it was in good condition. My attention was then drawn to another door that had so many warnings that I couldn’t see all of them, among the mess were Dangerous, Corrosive, Bio-hazardous, Authorized personnel only among others. To be honest, my interests got caught almost instantly, I grabbed both sides of the door and forced it open with no problem with my bare hands.

My eyes scanned the room for Demons immediately, there were several tables that lined the walls and littered the floor, the ceiling lights flickered on and off repeatedly, in the center were 8 sarcophagi that looked eerily similar to my own, symbols, stone and all. I noticed that along the tables were several cutting tools meant for stone, metal or other kinds of minerals, apparently whoever had set up shop here wanted the sarcophagi to be opened at all costs. As I was about to open one of them, my hand faltered on top of the first sarcophagus that I was closest to. ‘I’m not sensing anything demonic in these, but one can never be too careful.’ I thought as I grabbed the sarcophagus’ lid and tugged as hard as I could; the lid flew off its attachment and hit one of the tables, flipping it over. As soon as the lid flew off, I immediately pointed my shotgun at whatever it was that the sarcophagus had been holding and my jaw immediately dropped in surprise and shock. Lying before him was not a demon or anything relating to the aforementioned race; it was a girl, a human girl! At least I thought so at first, but that was before I brought my attention closer to her head; attached to her head was a single long and extremely pointed purple horn. Unlike a Demons’, as theirs were crooked, rough and gnarly, this girl’s was smooth, straight and almost... beautiful in some way. As I turned her over, as I had spotted something on her back, my eyes then caught a pair of wings on her back, I tried desperately to not wake her up, the wings were large and majestic, purple in color like her horn as well as her skin, each individual feather was visible if one looked hard enough, but from a distance, they looked like one piece of her body.

I then found that, like myself, all she had on was a pair of underwear, a bra and panties made certain not too much was revealed of her C-cup breasts and her... you know what. I turned so red, I was surprised that I didn't pass out at this revelation, I turned my attention to her physique, like me, the girl’s muscles were quite large for her body, I couldn't help but make a comparison based on what I said next: “Oh my god, you could grind meat on those pecks!” Her legs, arms and her torso were covered in muscle everyplace possible, if anything, without the horn, skin coloration and wings, she might have passed as a female version of me! My hand put pressure on a particular part of her neck, I felt a strong thump. ‘Pulse is strong.’ I noted, I then wondered what else could be in the remaining sarcophagi. I threw each one of the lids off and found girls of the following description: the first was a pure snow white, so white that I was surprised that she was alive. Hair color was even darker than the first, a pure dark purple. Her muscles were a little smaller than the previous girls’ but still not natural for a girl of her size, what really caught my eye were her D-cup breasts, but I shied away from that fantasy for now. Like the previous girl, she had a horn, noticeably shorter as well, however there were no wings. Upon closer inspection, the next one caught me by surprise at how beautiful she was, her natural curves, her stunning visage among other things. The next one was really different, completely pink in color, her hair darker than her skin, her breasts were far bigger than any other before, at Double-D, this girl was more cute than anything else, muscles were a little offsetting but still cute in her own regard, her hair was in curls and all over the place, like it wanted to be free of all inhibitions. Something about her however, screamed chaos to me, nothing else just... chaos is all that could be described. ‘What is she? For that matter what are these girls?’ I thought as I looked over the rest. The next one over was a bright cyan blue, rainbow hair and wings, breast size is average compared to the others, at C-Cup, something about her was almost like... she was a renegade, nothing else, just the kind of girl that did what she wanted... I like that... Her wings were slightly smaller than the first, but still looked like they could blow me away if I was off balance. Her muscles were even more pronounced than anyone else, aside from his, of course, almost like she was The Hulk or something. The next was a slight surprise, a girl with a horn that was as long as the white one’s and she was colored a bright yellow, about as yellow as the sun when viewed through an atmosphere I'd reckon. Her C-Cup breasts were somewhat disappointing, but I still found the rest of her to be rather pretty, the hair was the weirdest part though, it was primarily red with yellow highlights that almost made it look like bacon or wildfire or something... Next was a bright purple, almost lavender, brighter than the first, horn in place just like her predecessors, her F-Cup breasts were impressive, quite odd yet almost... enticing. Her face was one of beauty with a scholarly-secretary look to it that I found rather odd, but mixed well all the same.

After that was a more normal one like the pure pink one, her main color was orange, and she had that odd southern-cowgirl vibe to her that I couldn’t quite describe. Her Double-D breasts looked great on her body, strangely, her legs were the strongest looking part of her body, each one toned to their peak that they could handle. This one looked like the kind of girl I could take home with me or something. Up next was one who was a buttery yellow, this one’s breasts the largest at I-Cup and she had the correct body for it. Her muscles were in between that of the white and darker purple ones’, her face just screamed that of so much cuteness that my heart almost stopped beating entirely. “Wow, if that isn’t cute, then I don’t know what is!” I said out loud, I then wondered how they were still asleep, as I had talked quite loudly in their presence and they never woke. Thinking of something that would... probably get me in trouble later, I decided to try something even louder than myself; Shotgun! I put the barrel right next to the purple/lavender one’s ear and made certain none of the shells would hit her. I fired the gun and the girl didn’t so much as budge. “Wow! If that didn’t wake her, maybe a rock concert would do it?” I wondered, though I seriously doubt I would be able to find one on Mars of all places, as I had found out via datapad earlier. I then saw something that should have belonged to a demon; a Necronomicon! I had used one once before, but I swore never to use one again, as I was about to destroy it, I noticed something odd about it's cover that caught my attention; on the cover it said in Demon Speak; ‘Awakening the Elements of Harmony; The Instruction Manual’ Honestly, I was surprised that demons even had manuals to begin with, though I left that question for later. I picked up the Necronomicon and opened it, flipping through the various pages, I discovered within it's pages, that the girls were bar none the greatest warriors that another world, called Equestria, had to offer, the demons had wanted their power for themselves, much like his former masters’ Argent Energy.

I was certain that these warriors must have been tricked like me somehow, but I pushed the thought aside for now, I wanted to know more at this point. The Necronomicon went on about how the Elements of Harmony were an unstoppable power, yet also how they were in character, how one was shy, another rebellious, another wanting truth, a fourth being generous, fifth as a magic user, sixth as a party animal (I still wondered how large and diverse the Demon’s language had become during my slumber), seventh as a forgiven female and the eighth as one who learns from her mistakes. The Demons wanted their power very similarly to the Argent Energy that the Demons had stolen so long ago; so they may have their world as their own, without its defense, the world itself would fall to the Demons. It then gave instructions on how to awaken them, figuring I could take them on if they were under the demon's influence, I gathered the necessary materials, of which included Demon Blood, a human skull among other things. Once the ritual was ready, I began to chant in ancient Earth Latin: “Audietur eloquium meum per elementorum somno excitaretur e somno mentes!” The ground began to shake as a bright red glow enveloped the girls, a satanic ring formed around all the sarcophagi and I continued to chant, my voice unwavering at the strange happenings around me. “Harmonia Elementorum, voca me audies. Obsecro te, quod potes quaerere.” The whole place shook with the force of an earthquake as the glow brightened as the lights flickered faster and yet I still chanted, my balance keeping me upright. “Omnes inimici mei mihi et qui non diligit omnia quae sunt destrueret.” The girls began to convulse and shake as lightning burst forth from their bodies, some almost hitting me directly, but still I kept the incantation going. “Nunc segregari possunt oriri: et agros cum virtute, ex flammis!!” Upon the last word, the light became so bright that I had to shield my face from the blinding light. Once it died down, the girls still remained in their sarcophagi, unmoving in the flickering electronic lights. During one of the flickers, they all bolted upright with a speed unheard of to him. I then was caught by surprise by one of them moving, almost as though she teleported, right in front of me, in pure shock at her speed, I fell backwards, I hadn't seen any portal, no premade movements, nothing! She was most likely the fastest thing alive! The girl gently knelled before me and caressed the side of my helmet, making me somehow feel comfortable yet uncomfortable at the same time, it was sweet, but it also made me slightly suspicious. “Are you... the one who freed us?” She asked; her voice young yet scratchy from the years she must have been kept under the sarcophagus’ lid, I know mine was. I nodded silently, not certain if I could trust these girls yet, however, unexpectedly, all the girls in the room hugged me, leaving me absolutely shocked.

“Er... What’s with this?” I couldn’t help but ask as the purple one smiled. “We’ve just been trapped down there for so long that... we just... needed something to help comfort us.” I nodded in understanding, my arms then returned the hug as well. “I can understand why, you being trapped by those demons; that must have been damaging to you, being so young you know?” I asked, already knowing the answer. “I don’t even know if anypony in Equestria is looking for us! They must have given up!” The white one panicked, flailing her arms in distress. “Hey! HEY!” I shouted, making the white horned girl stop dead in her tracks. “Look! We cannot be panicking right now! Right now, there are demons out there and quite frankly, if we do survive this, I’ll find a way to get you all home, OK?” I suggested, making the horned girl look at him, nodding. “You’re right, that was very unladylike of me! I deeply apologize.” I chuckled, then turned back to the rest of the girls. “Now that that’s out of the way, I believe that introductions are in order.” The purple one nodded. “Of course, my name is Twilight Sparkle; this is Rainbow Dash (Blue w/ wings and rainbow hair) Pinkie Pie (all pink) Applejack (orange w/ blonde hair), Rarity (White w/ horn), Fluttershy (yellow w/ wings), Starlight Glimmer (Lavender w/ horn) and Sunset Shimmer (bright yellow w/ horn).” She introduced, motioning to all the girls with the aforementioned names. “What about you?” Starlight asked, curiously, I then hung my head a bit in sadness. “I... I don’t remember my own name.” The girls gasped in shock. “You don’t!?” Pinkie asked in her own shock. “It’s been so long since I’ve remembered, but I think... it is something like... John Grim or something along those lines, however, the Demons had always called me by another name... Doom Slayer.”
