Darkness filled the castle halls as Nightmare Moon traversed them, Twilight and Moon Beam following close behind. The filly was humming a happy tune, filling the air with cheer. Twilight couldn't help but to smile. Moon Beam is so happy. It's kind of infectious. It makes me wonder how Nightmare Moon could care so much for anything other than herself. She could see it in Nightmare Moon's eyes every time they were drawn to Moon Beam's antics. Is she truly Moon Beam's mother?

"Mommy, Auntie! Guess what!" They focused their attention on the giggling filly. "I think I saw somepony following ussss~!" She sang out the words prancing around the pair as she did.

From the shadows came a group of ponies, each wearing heavy metal armor and wielding weapons of various types. Swords, spears, and hoof-axes all gleamed in the sparse moonlight. "Ahh, I was wondering when you would return to try and kill me. I'm quite surprised any of the Canterlot guards still live. I thought you had all thrown yourselves to your deaths that first night."

They created a circle around the group, cutting off any exits they could imagine while a few unicorns on the perimeter of the guard line created a magical barrier, trapping them inside. Nightmare Moon attempted to conjure her magic but could barely create a shimmering blade before her. Surprise found its way upon her expression. The largest of the group stepped forth, his spear mounted beside him in a leather holster. "I am commanding officer Firebrand. You are enclosed inside an anti-magic barrier. If you do not surrender now, we will be forced to kill you where you stand."

Twilight looked up to Nightmare Moon, trying to read her thoughts, but she held the same impassive features of the last time she had been attacked. Moon Beam jumped out at them giggling. "Oh, you sillies. You cant hurt Mommy Moon~. I won't let you~."

The guards looked at each other and frowned. What was a filly doing with the likes of this demon? Why was she standing between them and her? And why was she still smiling? Firebrand stepped closer and brought his head down to the filly's level. "Please move out of our way. We do not wish to harm you. We want only Nightmare Moon and her unicorn cons-" His words were cut off by a swift kick from the filly's hind legs, bloodying his nose. His anger flared. "INSOLENT WELP!" In a single swift motion, Firebrand ripped his spear out of its holster and impaled the filly through the head, skewering her to the floor.

Twilight screamed out in dismay. "MOON BEAM!" She tried to rush forward only to be impeded by Nightmare Moon, her hoof holding the unicorn back. Tears filled Twilight's eyes. "HOW COULD YOU LET HIM DO THAT!? I THOUGHT YOU CARED FOR-" Her words cut of by a deep gurgling cackle, as if something was trying to laugh underwater.

The guards all stared on in horror as the impaled filly began to lose shape, the spilled blood flowing back into her. Twilight smiled slightly, relieved that Moon Beam was okay, even if she knew what was going to happen next. Her elation that the filly hadn't died overwrote all other feelings. The tiny navy unicorn, now a globular mass of hatred, opened its blood-red eyes, piercing Firebrand's soul with its stare. He couldn't move, couldn't blink. He could only look back into those sinister eyes, feeling them drain his life as they drew nearer. "I warned you that I would not let you hurt My Queen, and yet you failed to heed my words...." Her voice shook the air around her, its deep gravelly tone causing the ponies to flinch back. "I shall see to it that you will never... repeat this... again...!"

Dark tendrils shot out at him, grasping the commander by the throat as they slowly snaked up to his face. He opened his mouth to scream only to have the hellish vines rush down his throat, cutting off his voice. He couldn't feel the things inside him, but he knew they were there. He could feel them draining his life force. A large grin of sharp, gleaming teeth shone on the orb's form, just below the eyes. The guards watched on in terror as Firebrand's body began to shrivel up, his body drying up like a grape in the sun. When she finished, Firebrand's body dropped to the ground, dissolving into dust.

"Ahhh, it has been so long since I've fed upon you pitiful beings. It really is such a wonderful feeling to-" Her harsh words were cut short by a sword passing through her body, black blood spewed onto the ground before being absorbed back into her orb. "Ohoho, another brave pony wishes to strike me down?" Her form shifted, eyes disappearing before reappearing to glare at the pony that had struck her. Hot liquid poured down his legs as he turned tail to run, only to be impeded by the barrier meant to keep them in.

He pounded and pounded shouting at the unicorns to lower it so they could flee, but they refused. If the barrier dropped then even they would be killed. Moon Beam's body changed, taking on the essence of an adolescent dragon. Her form hardened, scales now covering it entirely. Her maw opened, deep purple flames, danced over her tongue, as she brought her head over the helpless pony before her. One final scream tore itself from his mouth as her jaws clamped down on his hind quarters, tearing through his flesh and biting him in half. Blood poured out of his wound and from between her teeth as she chewed and swallowed the morsel. The pony didn't die from the blood loss, as shock had stopped his heart.

Seeing their impending doom, the rest of the guards rushed Moon Beam, their weapons swinging at her. Cuts ran all along her body as the swords, axes, and spears all pierced her scales. She howled in fury and swung her tail, smashing two ponies behind her into a bloody pulp on the walls of the shield. The force caused the shimmering blue field to flicker. Another guard thrust his spear into her side, eliciting a yelp of pain before his head was torn from his neck by a swat from her clawed hands. She yanked the spear out and thrust it into the chest of an oncoming sword-wielder, pinning him to the ground with enough force to shatter the spear in his body. Blood pooled on the ground beneath them, making the floor slick and their footing poor. Ten more ponies remained, all of them forming a semi-circle around the dragon filly, Twilight, and Nightmare Moon.

Twilight stared on in shock, unable to control her stomach. She retched, spilling her dinner to mingle with the pooling blood at her hooves. The ponies stamped their hooves, preparing to charge the dragon in one last-ditch effort to bring it down. Moon Beam glared at them contemptuously. "You insects think you can slay me? A being with power second to only My Queen?!" They charged. Moon Beam merely cackled, before taking in a deep breath, filling her lungs with air. Before the guards could draw any closer, the navy dragon filly arched her neck, head facing the ponies before her, and spewed searing flames across their bodies. Purple plasma burnt their flesh off, then their muscles, and organs. She stopped the flames and watched as their skeletons tumbled to the ground, still moving forward from their momentum, before scattering before the trio.

Moon Beam focused her attention on the unicorns outside, shaking violently as they kept the shield up to save themselves. A malicious grin crept its way onto her face. She glared at the nearest unicorn, her piercing red eyes paralyzing her. "You are going to release the barrier," Moon Beam stated as if her words were a fact of nature. The unicorn mare began to shake again, losing control of her magic, before turning tail and running off down the halls, leaving a warm trail and her four companions behind her. The shield faltered, then fell, leaving the four remaining guards to huddle together, wailing in terror.

Twilight recovered from her sickness and looked up at Nightmare Moon only to find the mare grinning sadistically. She's reveling in their deaths and Moon Beam's fury...! The realization struck her like a concrete slab to her face. Moon Beam took a step towards the cowering mass, her claws scraping noisily on the ground. Another step. One more. Before she could lower her clawed foot something grabbed her around one of her hind legs. The sound of sobbing caught her draconic ears and she turned to see Twilight, her fore-legs wrapped around her, crying into her. "Please don't kill anymore...! Please.... I don't want you to become a monster...!"

Moon Beam's expression twisted, the rage in her eyes dying as Twilight's pleas pierced her anger-fueled heart. She slowly began to lose her draconic form, layers of navy smoke falling off her body to evaporate into the air around them. Twilight continued to hold her, her eyes clenched shut, until the filly was squirming in her arms, covered in blood and cuts. "Auntie Twilight? Why are you crying?"

The lavender unicorn shot her head up and smiled weakly at the little filly, nuzzling her softly. "You're back to normal.... good...." Moon Beam giggled and hugged Twilight back, reveling in the attention. While all the focus was on the two unicorns, the rest of the guards took off out of sight, fleeing for their lives.

Nightmare Moon scowled fiercely and stamped her hooves. "YOU FOAL! How dare you stop her from finishing them!? They will be back and next time they'll be prepared! Your insolence has cost you more than you can even imagine!" Her mane began to shimmer until it returned to its astral likeness, billowing in an unseen wind once more.

Moon Beam looked up to the alicorn and frowned slightly. "What did Auntie Twilight do? Please don't be mad at her...."

"Silence, Moon! She will pay for her interference!" The filly simply lowered her head, casting a sad smile Twilight's way. "You will go find Silent Brook and have her entertain you while I mete out my pet's punishment."

"Yes, Mommy...." The filly squirmed her way out of Twilight's arms and took off down the halls, her usual springy step missing.

After Nightmare Moon saw the navy filly turn the corner, she once more focused her rage-filled attention on the quivering unicorn before her. "I know not how you calmed Moon Beam out of her fury, but you shall pay dearly for getting in my way once more. You may have protected me before, but I will not tolerate your selfish actions." Her horn glowed and they both disappeared from the halls. There was no sign of either of them until high pitched wails of agony tore through the castle, stopping many workers in their tracks.

Silent Brook trotted down the hall, humming to herself as she went about her daily duties such as directing work flow and overseeing that all jobs were completed. She turned a corner and was bowled over by a flying mass of blue and black as it tackled her to the ground. "Hi miss Brook!" The filly stood on her chest, smiling gaily, but with a hint of sadness in her large red eyes. "Mommy Moon told me to come find you so you can play with me~"

Brook giggled, the filly that seemed so close to Nightmare Moon was such a contrast to the dark and sinister alicorn. "And why am I to be graced by such a cute little thing as yourself?" Moon Beam giggled cutely as Brook messed with her wispy mane. "Isn't Twilight the one that you normally go to?" In the few days that the filly had been in the castle, she had never seen her frown, even if this current one lasted for but a second.

"Auntie Twilight did something that Mommy Moon didn't like so now she's being punished..." The tiny unicorn's mood changed back to her typical cheerfulness. "But that's okay 'cause I know that Mommy Moon really likes Auntie Twilight~ She wouldn't ever spank her too badly~"

Silent Brook frowned, knowing very well that Nightmare Moon would indeed hurt Twilight, and severely at that. She forced herself not to show any hint of worry on her features, instead smiling back at the child before her. "You're right. Now let's go find us some adventure!" She shouted into the air followed by the cutest little squeal of joy she had ever heard.

"Yay! Adventure time!" The filly bounced around the lime pony and laughed as they took off down the halls, 'attacking' the workers as they went.

Twilight was huddled on the ground, panting heavily with several burn marks and cuts covering her body. Blood trickled out of the lacerations and colored her lavender coat a sickly red. Above her stood Nightmare Moon, a flaming ethereal whip floating beside her head. The unicorn could no longer cry, not for lack of trying, but her tears had dried up. The alicorn smirked before lashing Twilight with the whip once more, eliciting a pained yell and adding to the smell of singed fur already lingering in the air. Another lashing and another yelp followed by another.

The unicorn looked up at her Queen, her one open eye pleading for mercy to which the alicorn ignored, whipping her again. Satisfied with the amount of lashing, Nightmare Moon dispersed the magic holding the ethereal whip together and sent it off into the atmosphere. She stepped closer to the huddled mass and laughed. "You shall learn not to cross me even if I have to beat it into you. You will stay here and ponder what I have taught you. If you are as smart as I would believe, you shall come to the right decision and finally learn your place. Should you not...." Her evil grin reappeared as a large burning brand with a mimic of her cutie mark on the end materialized, floating inches away from Twilight's flank, "I shall permanently impart my words upon your body as a reminder."

Twilight could feel the heat radiating off the brand. She tried to slide away from it and plea for forgiveness, but the screaming had ravaged her throat, leaving her temporarily voiceless. Nightmare Moon cackled and released the magical brand then bound her pet to the ground with the glowing shackles. "I will send the head maid to clean up your..." She looked at the urine and blood stains on the floor, "mess...." With those final words, Nightmare Moon enveloped herself in her mane and shot off down the halls, wisps of astral smoke lingering behind until dispersing into nothingness. Twilight could only sit there, bleeding and wracked with pain, sobbing weakly into her magically bound fore-legs.

As time passed by, she could feel herself beginning to drift into unconsciousness, her exhausted body only wanting to rest, until a knock sounded on the door, snapping her focus back to her surroundings. The door opened and in seconds she was being smothered by a lime green pony. "Oh Celestia, you're hurt so bad! I can't believe she'd do this to you!" Sobs wracked Twilight's body once more as Silent Brook's embrace tightened around her. The earth pony showered her forehead with kisses. "Shh. Shh. Don't worry. I'm here for you.... Nightmare Moon took Moon Beam to bathe then play outside. We'll be alone for a couple hours.... Let's get you cleaned up and get those cuts bandaged."

Twilight simply lay on the floor, the cold rock like a soothing salve against her burning skin, as Silent Brook applied ointments from her saddlebag before wrapping her with clean white gauze. No matter how hard she tried, however, she just couldn't get the medical tape to wrap around Twilight's flank where most of the wounds had been inflicted. "P-Please.... My flank burns horribly...." The open air was making her wounds hurt more as if the air around her was another whip inflicting more pain upon her body. "Make it stop...." she whimpered.

Silent Brook stared at the dark lacerations on Twilight's flank thinking hard as to what she could do. An idea forced itself into her brain. "I.... I have an idea but it will sting a lot.... I'm out of the healing salve, but..."

"Please...! Anything...! Just help the pain...!"

This is going to be weird.... I hope she doesn't hate me for this, but I've read that saliva is a good healing compound.... She sighed and brought her mouth closer to Twilight's rear. "I'm going to lick the wounds.... Saliva is supposed-"

"To be a substance that can hasten the healing process.... I know.... Just please hurry...!"

"Okay...! I'll use one of the sheets to cover you when I'm... done...." A hot blush burned Silent Brook's cheeks as she slid her tongue out and drew it across Twilight's flank, the taste of metallic blood settling on her tongue. I've always wanted to do this, but never under these circumstances.... She slathered her saliva over Twilight's backside, tensing every time the unicorn flinched from her tongue darting across the wounds. She finished as quickly as she could, not wanting to cause Twilight any more pain, and tore one of the sheets off of the bed beside them, using it to bind the lavender pony's flanks. "There.... That should help it heal faster and the pressure should help to alleviate some of the pain...." She turned to face the unicorn and found her smiling weakly.

"Thank you...!" Twilight leaned her head forward and kissed Brook deeply. They broke apart, a strand of saliva lingering between them before breaking and sticking to their chins.

Silent Brook smiled lovingly, and edged closer to the unicorn. "I know a way that could take your mind off the pain for a bit...." Her voice was husky and hinted at possible pleasures to come.

Twilight closed her eyes, trying to ignore the fire that burned through her back and hindquarters. She wanted to tell Brook no. Tell her it was too soon. She had only ever given to her Queen and was nervous about having somepony else in her nethers. But the pain was too much. She wanted, more than anything, for the burning and throbbing to go away. "I... I..." Her vision was foggy through the pained haze. "Please..., make it go away...."

Silent Brook smiled sweetly at her, a smile that Twilight barely noticed, and moved back behind the unicorn of her desires. Gingerly lifting the sheets that covered her backside, Brook took in the sight before her. It was beautiful, even if marred by slight red marks from Nightmare Moon's beatings. She licked her lips, transfixed by the radiant garden, and gingerly slid her tongue up Twilight's backside causing the mare to inhale sharply. She licked again and again, her tongue sliding gently along Twilight's folds until she could hear her moan in delight. Smiling, the lime pony dug her snout into her soft love, shoving her tongue deep into her, twisting it and lapping at her insides.

Twilight shuddered, her anguish being washed away by waves of euphoria. She had never thought having somepony stick their tongue inside her would feel so... Amazing. She could feel wetness seeping as Brook pulled back, breathing heavily. Her hot breath tickled and sent chills up her spine. Brook brought her mouth closer. Twilight tensed, anticipating the hot moist tongue on her sex. The lime mare had other ideas. Twilight gasped in shock when the tongue pressed against her anus, instinctively clenching it tighter. Brook paid it no heed and instead rolled her tongue around the puckered hole, eliciting soft moans as Twilight slowly relaxed once more. As soon as she was able, Silent Brook dove in, pressing her mouth tightly on Twilight's backside and slid her tongue inside.

Twilight gasped, moaned, then melted under the hot ministrations Brook was performing upon her backside. It felt so wonderful, so surprising,... so right. She had never thought that her anus could give her pleasure, but here she was, enjoying Brook's tongue inside her backside more than she had with it in her love. Brook could feel Twilight growing more and more relaxed, her hole opening wider for her. She pulled out, much to the dismay of Twilight, and returned her attention to the mound below. It was sopping wet now and Brook could smell Twilight clearly. She softly drew her tongue up the slit, reveling in Twilight's taste. She was mildly sour and had an acidic taste, but to Brook, it was the best thing she had ever had. Lust filled her eyes and she shoved her snout back into Twilight, licking furiously, breathing in Twilight's scent as heavily as possible. She was in heaven even if she knew that she wouldn't be receiving the same attention afterwards. It was pleasure enough for her to be able to indulge in Twilight's love.

The lavender unicorn couldn't get enough of Brook's tongue. She wanted more. She concentrated on Brook's movements, taking in each time she moved her head and darted her tongue across her hard nub. She started to thrust her hips. Unsteadily at first, but quickly began to match the lime pony's movements, doubling her euphoria. Silent Brook pulled back, gasping for air, and noticed something just beyond Twilight's beckoning love. Two nipples standing erect between Twilight's thighs like little mountain peaks standing proudly on a field of purple grass. In one swift motion, Brook turned Twilight onto her back and latched onto one of the nipples, suckling on it, nipping it lightly. Twilight's eyes flew open, her legs tensed and the mound between her legs seemed to catch fire. "Oh...! Brook! Something's coming...! I-I can feel it.... Please don't stop...! Suck on my breasts some more...!"

Needing no other instructions, Brook doubled her efforts and sucked harder, bit more sharply. Twilight's body shuddered. Whatever was coming was so close. She could feel the fire in her body. A new fire, not the one that had pained her previously, but a burning wave of ecstasy. She bit her lip to keep from screaming and pressed Brook's head down upon her breasts with her fore-hooves. She came. The pleasure racked her body in waves as she moaned loudly, her thighs convulsing.

As the orgasm wore down and Twilight began to regain control of her lower body, she pulled the lime mare up to her face, weakly, but Silent Brook rose willingly, making it easier for the exhausted unicorn. "I've... never felt that... good before...!" She said in between gasps for air. She smiled, her face lit up by the post-coital after-glow. She was in heaven. "I've only given to Nightmare Moon. This was so... amazing."

Silent Brook merely smiled down at her and brought their mouths together into a deep, love-filled kiss. Twilight could taste herself on Brook's tongue. "I'll be glad to do it for you again. Nightmare Moon has no idea what she's missing." The two cuddled together on the now hot floor until Silent Brook eventually pulled herself away. She smiled sadly down at the unicorn. "I should probably leave now, before they return. I'll get you cleaned up again." She hastily gathered the soiled sheet on the floor and wiped Twilight down, pressing gingerly around the cuts to avoid hurting her as much as possible. She wiped the stains off the floor with the same sheet and trotted over to the door. She turned and smiled one final time before leaving, allowing Twilight to fall into a warm, pleasant dream on the hard floor.
