THE MOTHER OF ALL DEADLY SINS

BY THE YOUNG AND FREE DRAGON

CHAPTER ONE: BLINDED

Rainbow Dash was not sure how to tell Spike what she planned to tell him. She had been flying over the house and noticed a putrid stench. It must've been because of his cleaning or something. She had flown over the library everyday for the past few months, but until this month, when the sun had begun beating down on Ponyville, did the stench become pungent. She didn't know how Twilight could stand it in there, considering she had kept conversation to letters, and had been studying non-stop the past month.

What was she going to do? Knock on the door: "Hey your home stinks." Well, there surely was a more polite way to say it, but that was besides the point. It was still rude. But it was for everypony's sake really. If the two were studying so hard, they were neglecting to take proper care of themselves, then it was up to her to rescue them. She knocked at the door and stood back as she waited.

It was several long seconds before Spike answered the door. He looked a bit harrowed, as though he'd been studying long hours into the night. His scales were not very grimy or in any bad shape, but something seemed off about him.

"Hey Spike...you...uh...the library hasn't been smelling too good lately," Rainbow Dash stuttered, trying to find an easy way to tell him this.

"Yeah, I'm sorry," Spike said. "We're having a bit of a plumbing problem."

"Oh, okay," Rainbow Dash replied, nodding.

So they were having a plumbing issue. That wasn't a problem. Though they should have gotten it fixed a long time ago, especially if they were working 24/7 in those conditions. Something suddenly didn't feel right about this. That just didn't seem right. While Twilight wasn't as OCD as Rarity, she certainly wouldn't allow any sort of mess like this to go on.

"Can I get a book?" Rainbow Dash asked.

"You don't read, Dash," Spike pointed out, poking a hole straight through her plan.

"Well...I'd like to start." she said, thinking quickly.

"Okay, well then I'll get you something good to start with," he said, turning away.

"Wait! But I'd like to pick one out myself."

Spike was silent for a moment. Rainbow Dash was sure he was contemplating how to get around this, and her suspicions grew. But to her surprise, he opened the door further and left it open for her to come in. As she stepped in, she noticed that books were scattered all over the place. Some shelves were barren, some had a few books left on them, and others had only a couple removed from them. But either way, there wasn't a path that could be taken where a hoof would not land on a book.

"I kind of wanted to get it for you, because this place is a bit of a mess," Spike said, as he began clearing a path through the bookcases.

That kind of made sense. Spike was the one who cleaned up around the library, and if he had been slacking off for whatever reason, he might not want anyone to see that he had done so. But Rainbow Dash still couldn't see how Twilight Sparkle would let the place go. Speaking of the pony, she was nowhere to be seen.

"Where's Twilight?" Rainbow Dash asked.

"She's in the basement, working with chemicals. She said they're dangerous so she doesn't want anyone to come in," Spike said, solemnly.

Well he had certainly come up with that fast. Either he had that excuse already made up, he was a good liar, or he was telling the truth.

"So pick out your book," Spike said. "And while you do that, would you like me to fix you something to eat?"

That sounded like a good way to get him out of the room so she could go downstairs and see what Twilight Sparkle was up to.

"Yes, please."

Spike nodded and headed out. Rainbow Dash pretended to look through the books until she was sure Spike was in the kitchen and then she quickly exited the room and headed for the basement door. Whatever it was that Twilight and Spike didn't want her to know about, she was going to find out. She opened the basement door and was hit with a stench that caused her to recoil and strain to keep her lunch down.

The smell was horrifying. It clogged up her nose and lungs, and her head began to ache from the power of the stench. But it made sense to some extent. If the smell of plumbing problems would come from anywhere, it would be the basement, down closer to the pipes. She gagged and swallowed one more time. She didn't think Twilight was actually in here, but she had to be sure. She headed down the dark basement stairs. As she got farther down the stairs, she heard a muffled bubbling noise. She couldn't make out what it was, but it seemed to be coming from a place near to the bottom of the stairs.

When she reached the bottom, she felt a hoof around on the wall, feeling for a light switch. She couldn't find anything and kept traveling down the wall for about five feet before she found some sort of wench on the wall. She didn't really know what else to do, so she began turning it. She heard the sound of tired ropes creaking against wood as the wench worked some sort of pulley system. Suddenly with a fizzing noise, the bubbling became much louder and she heard the sound of hinges grinding. The wench stopped turning and all noise ceased, except for the bubbling.

She kept feeling down the wall, back the way she had came and on the other side of the stairs, she found a light switch. She flipped it up and blinked until her eyes became used to the dark. As she looked around, she gasped. The wench and pulleys had connected to a large trap door on the ground. Under it was a dark viscous liquid that bubbled non-stop. She stepped over to the vat and found out it was more of a tub, and it was only deep enough to submerge a full pony. But the liquid... Wait! Spike may have been telling the truth. This could be the dangerous chemical. But...where was Twilight Sparkle?

She glanced around and still did not see her anywhere. She also noted that the putrid smell was not coming from the liquid. She though that it would be the cause of it, but maybe Spike was telling the truth. A strange coincidence that a rather unpleasant smelling liquid and the plumbing happened to be in the same building. It was strange, but it had to be the truth.

As she was about to leave, she noticed a grimy sheet with something under it sitting near to the bath of chemicals, right behind Twilight's lab table. It was almost obscured there. She walked around the bath and trotted over to the sheet. She grabbed the end of it in her teeth and then yanked it aside. The stench that had been plaguing her suddenly became unbearable and she felt back, feeling like she was swallowing a rock in an attempt to keep her bile down. It wasn't made any easier as she looked down at what was emitting the stench.

A purple and blackish-red mess had been revealed. Blackened blood was pooled all around the corpse of Twilight Sparkle. The body itself was covered with dried blood, but deep caverns could be made out in her chest. Her stomach had been sliced open, but after the body had been placed on its back, the intestines had been pushed back inside, and were now only a bloody bath inside of the opening in her abdomen. They were black, red, and whitish. She now noticed there was also more white stains below the body.*

She looked up the body and saw that the holes that had been torn into her chest had been down with her own horn, which was sticking out of her throat. The horn was angled, and she could see twisted, and torn flesh of the jugular vein. As she finally rested her eyes on Twilight's face, she found it was contorted, as the mouth was twisted in a scream, while the eyes were wide open, but no eyes stared out. Instead only a dark cavern filled the holes. She was about to fall back and finally be sick, but she saw something else that finally did it for her.

She hadn't noticed it at first glance, but the intestines were squirming and moving. On closer examination, she found that Twilight's stomach was filled with maggots, as well as her own organs. Her eyes were moving, and they actually happened to be more insects, feeding on her ravaged body. Rainbow Dash fell back, gagging and finally was sick in the tub if acidic fluid. After her stomach was empty, and she had dry heaved several times, she finally looked up. What the fucking hay was going on? Twilight was brutally murdered and rotting in the basement of the library. She had to have been dead for a few days, so the letters that her friends had received the past few days... they hadn't been from her. Who could...?

"I told you that Twilight was working with dangerous chemicals down here," Spike said as he came down the stairs.

Rainbow Dash's eyes shot up fearfully. Spike did this. He had to. He had been pretending to be Twilight through letters so no pony would worry... So no pony would know that he had stabbed Twilight Sparkle to death with her own horn.

"Spike! What have you done?" Rainbow Dash cried as she stared up at the small dragon.

How had he even managed this? He was so small and innocent. How could a tiny guy like him overpower Twilight and...do this to her? Maybe he didn't actually do it. Maybe she was assuming too much. That still didn't explain why he covered for whoever did do it but...

"I know. I'm disappointed with myself," he sighed. "I meant to put her in the vat long before she started rotting like that."

Rainbow Dash's breath caught in her throat. "What do you mean, Spike?"

"I really am sorry about that the stench, but I've not had the heart to get rid of Twilight yet."

"Spike...why did you do this?" Rainbow Dash asked, tears welling up in her eyes.

She hadn't quite realized it yet, but her mind and body was beginning to understand that Twilight Sparkle was gone. She couldn't possibly be brought back. The last time she'd seen her, they'd simply exchanged greetings...she couldn't even remember the last time she had hugged her. She left her legs going weak. She fell to her knees and felt tears rolling down her cheeks.

"I really don't know Dash...but there's no need to cry. I can make it better."

She grit her teeth as anger flared in her and she would have tackled him, had she not been so weak from sadness.

"How? How could you possibly make up for what you've done?" She shouted, finally looking up at him.

She jumped as she saw he was standing right in front of her now and he took her face in his claws, though his grip was tight enough to keep her still.

"I can help you join her," Spike replied.

Before Rainbow Dash even realized what he meant, the claws of his thumbs had sunken into her eye sockets. She screamed and jerked backwards as the goo of her destroyed optical organs spilled out of her sockets. She was filled with adrenaline suddenly and she stumbled blindly away from Spike. She heard the roar of a Bunsen burner starting up and various chemicals beginning to bubble, as well as the crackle of electricity.

Rainbow Dash stumbled around, trying to avoid Spike and the pit of acid she knew was around here somewhere. But in her blinded state, she fell to her knees. Tears were produced from her tear ducts, and helped the blood to run down her cheeks faster. She jerked her head from side to side, trying in vain to catch Spike in one of her remaining senses. All was silent though.

"Spike!" She called out blindly. "Spike, please don't do this!"

The purple dragon didn't answer. There was no reason to. He worked quietly as he tied the ropes together. The Pegasus before him had broken into sobbing and screaming at the darkness, tortured by his silence. The ropes only made an occasional groan as he made them tighter.

Rainbow Dash had lost it. She wheeled about, screeching at every slight sound. She knew if she moved, she would have the chance of falling into the bath of acid. But if she stayed still, she would surely be murdered by the deranged dragon that lurked in the darkness. She let her cries die to whimpering as she lay down, prone. She began crawling forward, feeling every inch with her hooves to find a dip, which would mark the opening of the vat.

But suddenly, something grabbed her back legs and began dragging her backwards. She screamed as she could feel the claws of the dragon as he tightened his grip, no doubt dragging her away from freedom. She kicked and flopped about, trying to break his grip. But held fast and as she brought one of her hooves down to the ground, it kept going. Her hoof submerged in bubbling heat, and she screamed louder as she realized her mistake.

But as she withdrew her hoof, she was suddenly pulled upwards by her back legs and she felt ropes being drawn around her hooves and tightening. She tried to kick, but within seconds her hooves were tied up tight and she was hanging by her back legs. She screamed and flailed about for a few minutes before going quiet at the arrival of nothing. She had expected to have been dunked in the acid by now, or ''something ''happening. But there was nothing. Only the continued bubbling of the acid.

In this moment of quiet, she realized the searing pain in her hoof and she shook in fear and pain, crying silently. What could she do? What did Spike intend to do? Would he leave her to hang here? Or was he planning to butcher her in some horrifying way as he had Twilight Sparkle? Well... she had no horn... She couldn't be killed like that. Oh, who was she kidding? Spike was going to murder her no matter what, and she wasn't going to get out of it thinking irrationally.

So, what could she do. Well, the only thing she could think of was to try and swing back and forth and maybe break the ropes. But doing that gave way to the chance of the ropes breaking and sending her straight into the acid. Well, it wasn't as though she had a better plan.

She began swaying back and forth, using her wings to push herself forward, though they were too weak to help much. She was feeling a throbbing pain in her head, right where her eyes should have been, and she felt her pulse, pumping blood out of her ravaged sockets. If she didn't get away soon, she would die from her wounds.

She screamed when a pair of claws grabbed the hair of her chest and held her suspended forwards. The claws held tight and as she thrashed her front legs about, she felt her hooves hit Spike's face. She grabbed what she was sure was his cheeks and pulled him to her face so she could talk to him, though she could not see him.

"Spike please," She cried, her tears renewing themselves. "Please, let me go! I won't tell anypony! I'll say I had an accident while flying and a...stick poked out my eyes! I'll do anything if you'll just let me go!"

She felt Spike's breath against her face but he didn't speak and each sigh from his nostrils burned her bloody eye sockets. Finally, words formed and burned into her face.

"Would you... ring me your other friends?" Spike growled in a low voice, that was nothing like his normal one.

"W-What do you mean?"

"I'll let you live if you bring me...Rarity..." he hissed, almost as though it hurt to speak.

Bring him Rarity. She wanted to ask for what, but it was painfully obvious in her non existent eyes. He would kill her. Torture her maybe? Who knew what he had done to Twilight before he had delivered the final killing blows, and he'd done so much so far that Rainbow Dash knew she'd have nightmares for months.

It would be simple. Send Rarity over to check on Twilight. Say you heard she and Spike were sick. Spike would let her go and she could continue to live while Rarity suffered her fate at Spike's claws. But the ideas were mere flashes through her brain. She wouldn't turn in any of her friends, not for a chance to become a Wonderbolt, not for her own life.

"I...I can't do that..." she murmured. "Isn't there anything else?"

Spike was silent for a moment before he hissed; "You're sure?"

Rainbow Dash didn't hesitate. "I can't betray my friend-..."

Her pledge of loyalty was cut off as Spike's jaws closed down on her mouth with a growl and a snap. It wasn't a kiss. A kiss would have been tender and sweet. Spike dug his teeth into the flesh of Rainbow Dash's face and tore away what was around her mouth. She felt some of her front teeth sting as they were exposed to the cold air and her blood began flowing down her face. She screamed and threw herself backwards, but Spike's claws held on and dug into her flesh.
