It was a sunny day, only a few clouds littered the sky. Comet was trotting down a small path surrounded by small, grassy hills, a few trees scattered here and there, humming to himself. A sparrow was happily singing a tune in one of the trees while a few bunnies were munching on some grass or just simply enjoying the sunlight.

The gray unicorn had a cyan mane with matching tail, both being in an order only he understood, ‘organized chaos’ he used to call it. They were also a bit longer than the average stallions. His cutie mark was a book with black leather binding with a summoning circle depicted on it. He wore brown, well-used saddlebags that had seen better days if they had had a different color it was beyond recognition.

Inside the saddlebags were mostly common things like food, bits, a blanket and some other personal items. Namely a Necronomicon. Comet was as many referred to as a dark mage, he practiced the studies of magic that society condemned and was by a long shot from ordinary. While he didn’t hide his talent, he didn’t talk much about it. Many simply dismissed it as a talent for magic, which wasn’t a lie, he just didn’t correct them.

What Comet didn’t notice however was a pair of sapphire eyes watching him from a distance. Studying the individual carefully moving in like a serpent the eyes moved slowly as they stalked Comet down the trail. The owner of the eyes was glad for there was long grass in the hill that she could blend into edging closer to this unexpecting unicorn.


Shadow, or Princess Shadow if you will, was a hooves on ‘ling. While she had a harder time when mistakes happened, there were much less of them then she did it herself. Right now she was stalking her latest pray, a unicorn. Aside from the unusual color scheme, and the longer than an average mane and tail length, he was seemingly ordinary.

But Shadow knew better, there was something about the stallion, she just couldn’t put her hoof on it. But the itch in the back of her mind told her that something was amiss, that there was something special about him.

It drove her mad, she hated not being in control, to be out of the loop.

That was going to change soon, oh yes. She would find out and when she did when she did she would… Uh… Arg! I hate this! Why can’t things go the way I want them to!? Taking a few deep breaths to calm her nerves, she sighed. Can’t afford to lose further control now, remember Shadow, don’t let your emotions get the best of you.

Her azure eyes watched her pray, them being the only motion her body showed. The pony had yet to notice anything. And I’m planning to keep it that way. She waited for him to walk past her, but just five meters away, he stopped.

He was grinning. She was gritting her teeth. You have to be kidding me…

“Ah, this will be perfect,” His deep voice reached Shadow’s ears, causing them to twitch. He moved to the tree planted on the opposite side of the road from where Shadow was hiding. He had his back towards her only for a minute before he once again turned towards the road again. Shadow cursed under her breath, realizing that she might have to wait for a while.


Comet was laying on his blanket under a tree that was only a couple of meters away from the road. First, he had been intent on simply relax and listen to his surroundings. After an hour or so, he had the feeling of being watched but dismissed it in favor of his books. One was a journal where he kept tabs on how many supplies he had left, but also wrote down his thoughts. Munching down a slice of bread with cheese, lettuce and, more importantly, turkey, he wrote down to see if he couldn’t try to get more meat as he was running out. Most ponies would never even consider eating meat, but Comet wasn’t ‘most ponies’. Where others might not even spare a glance towards something, Comet would find out as much as he could about it. Hmm, I have to see if I can’t meet some Gryphon tradespony, hopefully, they’re willing to sell some of their meat, it’s pretty hard to get some inside Equestria.

After eating he got his other book, his spell book. He read and re-read some spells multiple times, making sure that he got everything right, but never actually casting any spell. During the whole time, he kept his ears perked, still having the feeling of being watched.

Sleep threatened to claim his consciousness as the sun settled. He had pulled out a second cott wrapping himself in its warmth. Normally they wouldn’t keep the warmth during the night, but Comet had enchanted both the one he was laying on and the one he had wrapped around himself, both offering much more protection from the cold than normally. Barely able to keep his eyes open anymore, he put back the book in the bags and instead pulled out a pillow. Sleep claimed him moments later.

As Comet came around, he noticed that something was wrong. He still had his blanket wrapped around him, but the one he had been laying on was gone. It was hard and cold, stone he decided. This was shown to be correct as he opened his eyes, but instead of being welcomed by the blinding morning light of the sun, he found himself in a dimly lit room, only a few lime luminescent crystal-like things providing light. Looks more like a cave chamber.

Reaching out with his magic, he studied the room, or would have if his magic would just work. His eyes going wide, he quickly pulled a hoof to his horn, but just as he felt the magic inhibitor at the base of his horn, he heard a voice.

“I wouldn’t do that if I were you.” It was a female voice, but it had a raspy undertone. Changelings...

As he turned around, he dropped the cott to the ground and gave the changeling a warm smile. The smile showed way too many sharp teeth than a pony should have. The changeling mirrored his smile, showing her own fangs.

“Tell me, what is your name, food?” The larger than average changeling spoke, a hint of amusement showing.

Comet didn’t as much as flinch, as he returned the question. “I may ask the same. Hmm, I don’t think I have had changeling before. Hopefully, they don’t taste as bad as they look.” He would never actually eat something sentient, but his captors didn’t need to know that. He licked his lips, trying to look the part.


Shadow’s smile fell, she gave the unicorn a stern gaze. “You wouldn’t.” She hissed.The same unnerving smile was still plastered on its face.Her gaze wavered as he didn’t. “Y-you wouldn’t.”

His smile turned into a grin as he tilted his head, he had normal teeth too she noted. His eyes showed no emotion. The expression was that of nightmares. Shadow shuddered internally, not being able to look away from those empty, amber orbs. She barely noticed the fire like smoke forming around the unicorn’s eyes, as fear started to take over.The room started to feel rather cramped, even though it roughly thirty square meters.

Just as she thought that she couldn’t take it anymore, the iron barred door flew open as a guard strode in. The voice of the armored changeling broke the spell that Shadow was under, she instantly noted that she had greatly exaggerated how sharp the teeth of the unicorn had been, the stallion resembling a lot more like a young colt getting his favorite treat than some creature born out of nightmares. “Princess! The Queen wishes to see you.”

Shadow grumbled something under her breath before she turned towards the guard. “I want at least two guards guarding this cell at all times until I say otherwise.” The guard was confused at first, but quickly gave a salute and went to inform the other guards.

She turned back to the unicorn. He hadn’t moved from where he sat, but instead of the grin he had worn, he looked inquisitively at the door. Getting an actual reading of his emotion she also noted that he was annoyed by something. She glared at him. “Whatever you did, you won’t get away with it.” She said as she moved out of the cell.

Closing and looking the magically reinforced cell door, she started to head out towards the throne room. She put on a stoic face, glad that changelings couldn’t read each other's emotions since they didn’t radiate the emotional energy. This was also a good way for changelings to separate disguised changelings from actual ponies.

She moved down halls seemingly at random to those that did not know the layout of the hive, each corridor looking like the other, the only difference was the changelings occupying them, some were guards wearing bluish armor and carrying spears, standing a bit straighter as she passed. Others were civilians chatting or simply walking around, every one of them giving a small bow.

Reaching two large doors marking the throne room, Shadow took a deep breath before she opened the doors. At the end of the large room was an obsidian throne, a smaller one to the right of it. In the larger one, Queen Chrysalis was seated, radiating power and elegance. A lime green carpet reached from the entrance all the way to the thrones. Guards flanked opposite sides of the room,the bottom of the thrones and the door.

As Shadow strode towards her mother, she spoke. “You wanted to see me, mother?”

“I heard you captured a unicorn.” Shadow froze.


Comet was laying down on the blanket they had let him keep. He was annoyed, he had almost managed to ‘convince’ the changeling to let him go, but that stupid guard had ruined his chance. Without his horn, he had to rely on the fear and doubt his captors felt to power his spells and even then was he only limited to a few spells as long as he had that darned magic inhibitor. Telekinesis and teleportation were out of the question, only spells he had were perception altering one’s, not very effective one’s either.

But it wasn’t a total failure, he still got some information from his captors. This was, of course, not the first time he had been captured. I guess it was a long time since the last time I was captured, it would have happened sooner or later. Still, wasn’t thinking that there were anypony interested in me in these parts, guess I didn’t think of changelings.

Not having more to do, Comet tried to get some sleep. Slowly he fell into an unrestful sleep as the world went dark.

Comet stirred. He moaned throatily, not having slept very well. He was still tired, and hungry. How long was it since he last ate? His stomach gurgled. Too long…

“You’re awake.” It was a statement, not a question. But something was different from last time he had talked with the changeling princess.

“You sound like you need somepony to dump all your frustrations at.” He had yet to actually see her, and from the sounds of it, she was behind him. He slowly turned towards her and rose to a sitting position. “It wouldn’t be the first time for me, my captors always seem to have something on their heart, but they don’t have anypony to listen to it. So I offer to listen if only to pass the time.”

“Hah, and why should I trust you? You already tried something last time.” Her deadpan would have caused Comet to flinch if it wasn’t for the fact that he was used to it by now.

He shrugged. “With the limiter, I am, as the name says, limited. It’s more or less useless if the one I try to use it on already knows about it. And since it didn’t work, I’m trying to, at least, get more comfortable while I’m staying. As for trusting me, well, you’re my captor, you never thought I’d, at least, try to escape once? But if I promise something I won’t go back on it, and I promise I won’t try to affect your emotions again, not directly at least.”

She stared at the stallion for a while, having monitored his emotion the whole time he spoke. He wasn’t lying as far as she could tell. She sighed in annoyance. “You want something, don’t you?”

“Well, yes. I’d like to have my freedom, for example. But I doubt you’d be willing to give me that. I would appreciate food though. Oh, and perhaps a mattress, if I’m going to stay here for long, I’d, at least, want to sleep well.”


“You aren’t in any position to bargain food,” Shadow said standing up and looking him carefully as she began to pace around him in a circular motion. A tactic her mother used to get information from Shining Armor before hypnotizing him and failing to take over Equestria. Great going mum “Tell me this why should I let you a worthless pony have a luxury even the drones don’t receive.” She added with a devious smirk.

Comet smirked himself, stretching, his joints popped. “You want something from me, if you didn’t you would have put me in a cocoon. Now, I’d be more willing to help you if I got something to eat. I already got the upper hoof of you once, I could do it again are you willing to risk that? Really, only that guard coming freed you from my grasp. So, do you want to take the easy route, or do you want to take the hard one?” His smile was gone, leaving his expression emotionless.

“You’re not one to demand something, you’ll have to eat sooner or later and we’ll provide the finest leftovers we have my dear ‘guest’,” Shadow said in a sarcastic tone, smirking as she looked this food “But you was right we need you, well not you yourself we need what you have inside you. Love. When we’ve extracted the essence then we’ll put you in a conversion pod.” She began to laugh as she paced a bit of her mother’s madness within her.

Comet started chuckling himself. “Oh, you’re really funny, you know? Even with a magic inhibitor was I able to best you, and if you want to gather love from me, then be my guest. If you find any, that is.” His chuckling intensified until it was a maniacal laughter.

“Oh, we will trust me even Sombra had love deep deep within him, mother knew that she used to court that lord of darkness before I was even conceived.” Shadow retorted with a cold glare and a devilish smirk “You my dear a just an ant compared to his evil, we’ll find love within you, and then you’ll be one of our mindless, docile, obedient drones.” She finished her rant with a spit at his face. The substance was a green gloop kinda like a jelly but slimy and sticky.

Comet didn’t flinch though, he only smiled. The smile turned into a grin soon after, but not an ordinary one, no, his overly sharp teeth made sure of that. “It’s your mother, isn’t it? She always tells you what to do, and you hate not being in control.” Using the doubt that flared for a second in Shadow, he powered up a new spell. As he did, his shadow grew, swallowing all light in its path, defying logic. Then it opened its eyes, a grin forming on the shadow.

Shadow couldn’t leave his gaze, everything else lost in darkness, his face the only thing visible. He threw himself at her, mouth unnaturally wide.

Shadow flew up from bed, sweat running down her forehead. Her expression turned into a frown. Only a nightmare. Everything felt so real though. She needed answers, and she needed them now.

chapter 4 (clop?)

Shadow was tired, she had woken up at midnight due to some stupid nightmare. Worse yet, she had had trouble going back to sleep again, leaving her tired all day. Her mother had asked her to come see her later, that was something Shadow was annoyed about. Her mother always talked down her, as if she was still a hatchling. I’ll show her that I’m no hatchling, I might not be as powerful as she is, yet, but strength is useless if you don’t have a brain.

She headed towards the cell that the unicorn she captured was in. The guards opened the door as she stepped in.

“Good morning, princess.” It wasn’t the guards that spoke, no, it was her captive. “Or should I say ‘bad morning’?” He sat in the back of the room, his blanket wrapped around his shoulders.

“Why do you try to torment me, food?” Shadow said looking at him with a cold glare “You won’t ever be let out so stop trying, but thank you for the formality.” She was annoyed yes but she always liked her food realising her as not any old changeling. It pleased her.

“You sound tired and nervous. You just have to ask, you know.” Comet smiled, his eyes the only thing showing that he was tired. “I also didn’t mention anything about trying to break free.”

Shadow wasn’t sure what Comet meant by ‘You just have to ask’, but she couldn’t stop from thinking that he said it as an offering to ‘service’ her. She pulled her tail closer to herself, lest she shows any signs of arousal from the thought of having him as her ‘pet’. A blush still managed to slip through.

He gave her a questioning look at her odd behaviour but quickly shook his head. If he had to stay here for a longer time, he could, at least, try to make himself as comfortable as possible.

Suppressing her perversive thoughts, she narrowed her eyes. “And just what is that supposed to mean?”

He smiled again. “Well, that I’m willing to help you if I get something in return. I’m feeling rather hungry, so, if you bring me something to eat, preferably meat, I’ll help you with something. Just try to be reasonable in your requests.”

You can eat me out. Her eyes grew in shock of her own thoughts. She couldn’t stop herself from thinking dirty thoughts anymore, she needed to relieve herself and fast, she couldn’t show a hint of weakness, not now, not ever. She needed to go, now! “Don’t get your hopes up.” She said as she left.

She hurried back to her room and looked it, not wanting to be disturbed. She flopped down on her bed with a grunt of frustration. What is this pony doing to me… and why is it turning me on? she thought grunting in frustration, Come on Shadow you’re a princess you can control you lustful urges...right? She was proven wrong when she felt a tingling sensation build up within her nether regions. She began to feel sweaty and flustered and was heavily blushing. Urg… let’s just get this over with…

She let the thoughts flow freely, starting simply from having some handsome changeling flirting with her. But soon the changeling was replaced with her captive unicorn, he would compliment her on her brilliance, her talent to manipulate others. Soon they were both on a bed, Shadow laying on her back, her legs spread. The unicorn lapping up her dripping nectar.

Outside her fantasy, shadow lets one of her forehooves slide down to her vulva, making small movements. She let out a small moan on contact, but was otherwise mostly quiet.

He would alternate between giving slow licks, sometimes penetrating her outer lips, to sucking and nibbling gently on her clit. Other times he would nibble on her engorged teats while he massaged her love button.

Soon they switched place, Shadow giving the stallion a blowjob in her fantasy. She would alternate between long licks from the base of the shaft to sucking on the head.The unicorn would moan or grunt in pleasure, unable to do too much than to watch the mare grow bolder with each passing moment. She started bobbing her head, taking a little more of the hard meat in her mouth each time she went down, until she took the whole thing, fighting back tears from not getting enough oxygen.

A few seconds later she came up again to take a few deep breaths, but instead of going back deepthroating the unicorn, she rose. She walked on top of him, positioning his stallion-hood so that it pressed against her entrance. She pushed down hard with a heavy moan as his length penetrated her virginal passage sending waves of pleasure up her spine. In the beginning, it was only small, slow motions, but Shadow sped up, the unicorn joining in, until both changeling’s and pony’s hips were a blur.

Shadow came, hard. She went limp as her orgasm rocked her whole body, as her problems seemed to wash away with the waves of pleasure, nothing else seemed to matter. All too soon it was over, leaving her as a panting mess. Damn, I haven’t come so hard in a long time. I don’t find him that attractive, do I? Nah, why would I?

A few knocks on the door interrupted her musings. “N-not now, come back later!” Shadow blurred out, wanting to take a hot shower. Oh yes, a hot shower sounded good right now.

“Princess, the Queen was expecting you ten minutes ago!” The guard, by the sounds of it, reported.

Shadow quickly turned her head to the clock, and yes, she was indeed late. “J-just one moment!” Crap, crap crap! I can’t go out now! Not like this! What would the drones think, what would mother think!? They’d laugh at me! She quickly went to the bathroom, picked up a towel, wetted it and quickly cleaned herself up , to make herself, at least, presentable, if just barely. “Tell her I’m on my way, just a little- hiccup, yes. I’ll be there within the minute.”

Moments later, she was dashing to get to the throne room.


Comet was laying on the stone floor, wrapped in his originally sky blue, now more brown with grime, the room not very clean. This what he spent doing most of the day, thinking on what he knew and applying that to different scenarios. One thing was clear, though, he needed to gain their trust if he were to escape, and soon. Each moment he grew just a little bit weaker and while he could probably last a week more, sooner or later he would be too weak to escape at all.

He had already planted the seed, that he could be trusted, in the changeling princess’ mind. It gave differently, but not necessarily bad, results than what he had expected. There was something he was missing, something he might have overlooked? Perhaps.

He needed a new, or, at least, change the old, plan. He needed the changeling to let down her guard, if only for a moment. And then he would strike, metaphorically of course. Yes… That’s it.

chapter 5

Comet sat in his cell the two changeling guards watching his every move like hawks waiting for him to do something. He didn’t. This was causing the guards to be tense as hell. Most pony prisoners would be begging for freedom or trying to overpower the guards or trying to make deals with ‘em, something at least. Comet, on the other hoof, did nothing, he just sat only moving when he breathed, ate, drank and slept and the guards hated it they wanted any chance they got to punish a prisoner, however, Comet didn’t give them the slightest of reason. He was playing with them in some sadistic game. A game he was winning.

Unbeknown to the guards, small smoke-like flames came out of the sides of Comet’s normally amber, now reddish, eyes, hidden with a perception filter. After Comet felt confident enough that the guard only saw what he wanted them to see, he rose up and walked forward, stopping only a few hoof lengths from them. He never broke eye contact, lest the spell fail before he wanted it to. He then altered the perception filter to show his current location, tilting his head and grinning madly.

The guards blinked. Twice. When the realization that the prisoner had moved without them came, they quickly backpedaled, seeing as the prisoner just appeared before them, plastered with a grin that had both guards shuddering. “B-back off, food. I-I’m warning y-you!”

They were expecting some kind of insult or snark, but Comet didn’t answer, or move at all, he didn’t even breathe, he just kept grinning. Or that was at least what the spell made the two changeling think. He still breathed but trying to be as quiet as possible, the spell doing nothing to alter the sound. But soon enough was it starting to get hard for Comet to not blink, He moved back to the same place he had been most of the time since his capture, quickly ending the spell afterwards.

The guards finally recovered their stoic mask for the spell to end. They tensed up as Comet rose and stretched some, but instead of rushing towards them, he simply laid down on his cot. He gave them a lazy look, before yawning and laying down his head on one of his forehooves. He was quickly asleep, a somewhat unrestful one. The guarding changeling was tense the whole time, fearing that something might happen if they looked away, even for only a second.


“Princess Shadow.” A small drone messenger said as Shadow walked the corridor towards Comet’s cell.

“Yes little messenger?” Shadow asked looking at the drone with a fake smile after her meeting with her mother she always felt like shit. “What do you wish to tell me?”

“The prisoner he’s uh… scaring the guards.” The young messenger said kinda scared of what he thought her reaction would be. But that reaction never came.

“Don’t tell the queen about this, unless you want your fellow changelings killed.” Shadow said calmly as she looked at the messenger with a sigh “I’ll deal with the matter myself.” The drone nodded and left as Shadow headed to the cell a little faster than she was before.

“P-Princess?” The guard at the door quivered seeing her “I’m s-sorry he…. He moved without us seeing…. We failed to, uh, see?” He was expecting a punishment, however, it never came.

“I don’t blame you…. Just don’t tell the queen, otherwise, you won’t be let off lightly.” Shadow sighed as she opened the cell door turning to the guard once more “I’ll deal with him” She said sternly before entering.


The metal door swung open, waking Comet up from his, yet again, restless sleep. Groggily he noticed a black figure heading in. The voice, however, removed the cobweb of sleep, being all too familiar. “Hello, food.”

Blinking away the last of the fog, he replied. “Morning, Princess. Though, if I’m perfectly honest, I think it’s due time we had a proper introduction. I am Comet Trail, also known as the wandering mage or the dark mage.”

The changeling princess stared at the unicorn for a few seconds. “Dark mage?” She asked confused “You don’t seem too dark to me… my mother could do a lot darker things than to just scare a few guards.” She tried to boast about her mother, but if he would have looked closer at her sides he would see her mother’s ‘work’ on her body. Thankfully for her he didn’t notice it, or simply not showing that he did.

“Well yes, I try to fit into society, but I am, in fact, what ponies call a dark mage. Though, I would have thought that you knew that, that is if you went through my things you would know.” Comet replied, looking somewhat confused. “You did look through my stuff, right? Right?”

Shadow gave him a look that said, ‘Should I have?’ She asked with a look of confusion on her face. “We have no need for your belongings, and so, we don’t bother looking at them, we just left ‘em where we found you, food.” She then added more sternly to not show him any weakness.

Comet stared at the changeling princess. Then blinked. “You’re kidding, right? Right?” With a shake of his head, he continued. “Not a single pony have done something as stupid when trying to capture me, not a single one out of three hundred and sixty-one. You never, and I repeat, never leave the one who you’re foal napping's stuff at the crime scene! Why would somepony just leave books about complex, and in the hoof of an experienced caster, dangerous spells! You don’t leave books in general, have you no respect for literature?” Comet was getting ready to snap at the next thing that spoke. Nopony treats books that bad, nopony!

Shadow was surprised, to say the least. The unicorn had been calm the whole time before, but when he started to talk about books, especially them being ‘mistreated’, had riled him up quite effectively. Hmm, perhaps I can exploit this? Shadow thought as ideas, while silly sounding at first, but with their findings giving them more ground, entered her mind. Even though she actually had her own library but that didn’t matter in exploitation. “What it’s easier than burning it. We are low on coal” She teased her fangs in a smirk. “And what’s so special in these books that mother just can’t teach me?”

Comet managed to calm down, seeing the empty threat for what it was, an empty threat and gave the changeling a weak smile. “I prepared for that, it won’t work. As for what the book can teach you that your mother can’t? Well, I wrote it, those are my spells, spells that I created. But to you, it wouldn’t show you anything, as I said, I was prepared.”

“Prepared…? You knew we would capture you effortlessly? And besides, I don’t require you puny spells.” Shadow said looking at him her fangs in a profound smirk “You’re nothing compared to the darkness of mother.” she sounded more arrogant than usual since her last ‘talk’ with Chrysalis.

Comet burst into a fit of laughter, not really trying to hide it. “Sorry, sorry, it just that I don’t believe you. You and your kind reek with fear, fear that strengthens me. Next time we meet it will be on my terms. Now I believe your ‘mother’ might want to have another ‘chat’ with you.” Comet smirked at the now silent changeling.

Just as she was about to rebut, a guard came, informing her that the queen wished to talk to her. Shadows snout turned into a snarl as she left, cursing at the unicorn for his luck.

Not soon did Comet slump down, yawning out of tiredness. Well, I think I at least an idea to get this thing off me. Getting a guard to do it should work, and once it’s off I can finally get to use my latest spell.
