Disclaimer: The Vampire Diaries are not mine. In some parts if the dialogue looks the same with the show, well it is. I only own the character "The Dark One" also known as Cvilidreta and her past.


01; a deal with the devil?

Damon Salvatore couldn't stop looking at the blonde girl sitting in his couch, after what she did to him; he was being cautious and careful watching every single move she made but it was pretty difficult and uncomfortable because she knew what he was doing, in response she was looking at him, smirking; Damon felt like she was staring right into his soul, scanning every single event, every single kill he had made in his vampire life.

Oh, he couldn't wait anymore; Stefan and Bonnie summoned Elena to come to the warehouse for the sudden event. When Stefan called Elena, he and Damon were told by the doppelganger that she un-daggered Elijah Mikaelson, one of the Originals. The Dark One told the brothers to not say a word about her to the Original, confused they asked why, in response she glared at them, it was enough reason for not telling him, they certainly didn't want to piss her more.

Elena Gilbert entered the warehouse without Elijah just like she promised, when she walked into the living room she suddenly stopped when she saw everyone looking at a smirking blonde girl sitting, she could feel the tension in the air, confused she questioned out loud.

"Who are you?" the doppelganger asked. Everyone turned at her quickly, the blonde girl disappeared in the air making her gasp in shock, one second later she appeared in front of her grinning.

Elena backed away immediately but the blonde girl grabbed her face and started to scan it "Stefan" she called afraid.

"Don't worry, she won't hurt you" her boyfriend said nervous.

The unknown girl pursed her lips "How irritating must be for you" she said "Looking exactly like Katerina, because, well you know, she was your boyfriend's ex" she started to giggle, Elena struggled against her grasp but of course it didn't work at all.

"Who are you?" she asked again. The blonde let go of her, grinning she bowed.

"I'm the Dark One, dearie" she answered "Your friends here called for my help" before the doppelganger could talk, the blonde continue "Now that we are all here" she turned to Damon "What do you want?"

"We need your help" Bonnie said. The Dark One rolled her eyes.

"I know that" she said "But now that I see your friend here" she pointed at Elena "This must be about the sacrifice right? Klaus trying to kill her to break the curse" Elena's eyes went wide.

"You know about the curse?" she asked curious, maybe she didn't know that it was actually fake or that's what she thought.

"Of course, love" she clapped her hands happily "I know everything" Damon narrowed his eyes at her response.

"Well you know then that it's fake" Elena told her scoffing "The Sun and the Moon curse it's not real."

"Dah" the blonde said "Klaus and Elijah faked it to hide the real curse, you know Klaus' werewolf side" grinning she continue "You shouldn't presume that you know more than us, you only find out an hour ago thanks to Elijah."

"Whoa, whoa, whoa" Damon interrupted "What do you mean with fake? And Klaus' werewolf side?"

"Well, the curse of the Sun and the Moon its fake, Elijah and Klaus created it a thousand years ago as a way to use the vampires and werewolves to look for the doppelganger."

"But if there's no curse..." Stefan started.

"There's a curse. Just not that one. The real one's much worse. It's a curse placed on Klaus" the Dark One continued.

"What are you talking about?" Bonnie asked confused.

"Klaus has been trying to break it for the last thousand years" the blonde then pointed at Elena "And she is his only hope."

Damon annoyed asked the right question "What is this curse?"

The blonde turned at Elena "Do you want to tell them or should I?" Elena gulped nervous and nodded in sign for the blonde to continue and not her "Klaus' family was quite close, but Klaus and his father did not get on too well. When they became vampires, they discovered the truth. Klaus was not his father's son. His mother had been unfaithful many years before. This was her darkest secret. Klaus is from a different bloodline" Elena was still in shock, the blonde was saying the same information Elijah had told her before "Of course, when his father discovered this, he hunted down and he killed Klaus mother's lover and his entire family. Not realizing, of course, that he was igniting a war between species that rages until this day."

"A war between the species?" Bonnie asked confused.

"The vampires... and the werewolves" the Dark One answered.

"So Klaus' real father was from a werewolf bloodline? What does that make Klaus?" Stefan asked confused at all "A werewolf? Or a vampire?"

The blonde grinned "He's both. A hybrid would be deadlier than any werewolf or vampire. Nature would not stand for such an imbalance of power. Therefore the witches, the servants of nature, saw to it that his werewolf side would become dormant."

"Fan-fucking-tastic" Damon muttered.

"So, that's the curse that Klaus wants to break?" the young witch asked.

"He wants to trigger that part of him that's a werewolf. If allowed, Klaus would sire his own bloodline. He'd build his own race. Endangering not just vampires, but everyone" the girl shrugged "In my opinion that would be so entertaining."

"What, are you saying that Klaus can't be killed because he is a hybrid?" Damon asked in disbelief.

The Dark One snorted" "Oh dearie, I could easily kill him any time but he is so funny, you know, once I made him belief his father was getting close" she laughed as he she was getting off the topic "Oh you should have seen his face, he was so scared like a little puppy."

"Dark One" Stefan called "A witch can kill him?" he asked not wanting her to get away with the topic.

She nodded in response "A witch if it can channel that much power. But it would kill her or him" she turned at Bonnie "So you will die, dearie."

Damon lifted his hands intervening "Okay, so this is the deal, you save Elena and you can have the two Originals."

"And why would I want those two?" the Dark One asked scoffing "Not good enough Damon, try again, remember I don't like when someone wastes my time."

"You said Klaus was your little toy, well if you stop him from killing Elena then that would piss him off, think of this as a one funny trick you could play to him" Damon suggested giving her a huge smile, in his mind he was praying for this to work.

"Oh, you are so good with words" the Dark One complimented him "And because of that marvelous idea, I will accept, but I still have my conditions."

"Which are?" Stefan asked curious.

"Klaus will break the curse and become a hybrid, he won't die" she said, immediately everyone started to protest, annoyed with a snap of her fingers, she shut them up "Don't interrupt me" she warned "Elena will die but she won't stay dead."

"What do you mean?" Elena asked confused.

"I believe Elijah told you about the elixir" she said to the doppelganger who nodded in response.

Damon scoffed "You are telling me a magical elixir will revive her?" the blonde nodded in response "Are you sure it works?"

The Dark One scoffed offended "Of course it does, I made it myself" she looked at Elena "You'll die, then you'll come back still as a human, no need to worry, of course unless Damon here has an objection" she pointed at the older vampire.

"How do we know you won't betray us?" Bonnie asked not sure.

"I never break my deals" the blonde said serious "Never had, never will as long as the other side never do it too."

"Then I guess we have a deal" Stefan said sighing.

The Dark One grinned "Very well" she took out her hand in front of him, Stefan shook the hand, the others did the same "Good, Elena" she said turning at the brunette "You can call Elijah, after all he needs to believe you'll kill Klaus on the night of the sacrifice" she nodded and called the Original "By the way you will have to try and ruin the sacrifice, like for example freeing the vampire and werewolf he has, that would really make him angry" she said grinning "Oh, I'm really loving this."

"He will be here in a few minutes" Elena told sighing after she hung up. The Dark One started to speak.

"You will not say who I am, for him I'm just a young witch who got caught in the middle and will help you so Bonnie won't die because of her magic, understood dearies?" Everyone nodded in agreement "Good"


Elijah knocked the door of the warehouse minutes later from the call of Elena; she had talked with the Salvatores' and everything was fine. Elena opened the door and invited him in. When the Original make his way inside just like Elena before, he froze when he saw the new girl in the living room. The blonde turned at him and smiled.

"You must be Elijah" she said walking at him "A pleasure to meet you" he shook his hand with hers, without letting her go he asked.

"I'm sorry we haven't been introduced yet, may I ask who you are?" he asked smoothly. The blonde let out a small laugh and smiled.

"I'm sorry" she said "My name is Cvilidreta."

"Not a very common name, may I say" the Original replied.

"I know" she shrugged.

He smiled "How do you know Elena Gilbert?"

Cvilidreta sighed "Actually I heard rumors about the doppelganger being here in Mystic Falls, I knew your brother Klaus would be here, I'm a witch, Elijah, my job it's to maintain the natural order, so I will help the Salvatores and Elena but specially Bonnie Bennett with her magic" Elijah listened carefully "With two witches you have more chances to kill him."

Elijah nodded understanding "Well, I appreciate the help."

"You're welcome" she said "So, shall we continue with the plan?" the Original nodded, he stepped back to let her walk into the library where the others were.

"Gentlemen, tonight is the full moon. We should assume that Klaus is prepared to break the curse" Elijah immediately said the others.

"Elena said that the Sun and the Moon curse is fake?" Stefan asked faking "That it's actually just a curse placed on Klaus."

"Klaus is a vampire born of a werewolf bloodline. The curse has kept his werewolf aspect from manifesting. But if he breaks it... He'll be a true hybrid" Elijah admitted sighing, Cvilidreta touched his arm in comfort, the Original gave her a smile in return.

"All right, how do we break this curse?" Damon asked.

"Well, the ritual itself is relatively straightforward. The ingredients, so to speak, you already know" Elijah said.

"The moonstone" Stefan said.

"A witch will channel the power of the full moon to release the spell that's bound within the stone. After that, Klaus, being both werewolf and vampire, will sacrifice one of each" The Original continued.

"And where do I fit into it?" Elena asked him.

"The final part of the ritual" Elijah took a wooden box from the shelf "Klaus must drink the blood of the doppelganger... To the point of your death" Damon looked at Elena. Stefan took Elena's hand. She looked at him. He opened the box and took a jar from it.

"And that's where you come in" Cvilidreta said.

"This is an elixir that I acquired some 500 years ago for Katerina. It possesses mystical properties of resuscitation" The older Original told the brunette.

"So I'll be dead?" Elena asked.

"And then you won't" Elijah replied.


After their discussion, Damon and Cvilidreta went to the Grill, minutes later Alaric joined them.

"So, you are the Dark One?" Alaric asked looking at her; she nodded grinning "You don't look like someone who should have that title. She laughed a little.

"Oh dearie, this is not my real form" she told him "I'm using magic to hide my real self."

"Then how do you look like?" Damon asked curious. Cvilidreta turned at him and smirked.

"If I showed myself right now, I can assure you that everyone would start screaming" the blonde told him.

She wasn't lying, her true form was horrible, she had green scales all over her body, her eyes were red like a ruby, her teeth were just like the fangs of a vampire, every single one. She couldn't go around showing her real face, she only do it when the situation was required or when she had to scared people.

In the dark days the people used not only to called her the Dark One also some used to say she was a crocodile, a snake, any name of a reptile that was known because of her skin but everyone who called her like that she immediately killed him or her.

She was the definition of a monster, her heart was prove of it; her heart stopped being red a very long time, slowly everyday it turned black from the darkness she possessed.

"Come on, it can't be that scary" the vampire teased. Cvilidreta smiled.

"Believe me, it is" she told him serious, before anyone could said something else, she felt the presence of the soon to be hybrid getting close to them "He is here" she muttered quietly.

Immediately Damon and Alaric turned, she rolled her eyes at their bluntness, couldn't they be more discrete? The blonde knew how Klaus looked but they didn't "Which one?" Alaric asked quietly.

"I don't know maybe the blond guy that is coming directly to us" the blonde girl said sarcastically.

The vampire and the hunter knew right away of whom she was talking about, the tall, blond guy with blue eyes was Klaus, and he was coming to them smirking like he owned everything. The Original stopped in front of them and the two males gave him a glare making the Original's smirk grow more.

"Gentlemen? Why so glum?" Klaus asked them not noticing the blonde by their side.

"Ugh. Klaus, I presume" Damon said faking a smile.

"In the flesh" he replied then looked at the hunter "Thanks for the loaner, mate."

Damon got up "Any reason you stopped by to say hi?"

"I'm told you and your brother fancies my doppelganger" Klaus said "Just thought I'd remind you to not do anything you'll regret."

"Ha" Damon faked a laugh "Thanks for your advice. I don't suppose I could talk you into a postponement, by any chance, huh?" the vampire said.

Klaus chuckled "You are kidding" he looked at Alaric "He is kidding, right?"

"No, not really" Alaric muttered shaking his head.

"I mean, come on" Damon started to say casually "What's one month in the whole grand scheme of things?"

"Let me be clear..." Klaus started to said taking a step closer in a threaten way "I have my vampire. I have my werewolf. I have everything I need. The ritual will happen tonight. So if you want to live to see tomorrow, don't screw it up."

"Well it was just a suggestion, mate" Damon mocked. Klaus throw him a glared.

"Young vampires, always thinking they can act like they own everything when in reality they are so below to us" Klaus told him, he grabbed the blue eyed vampire's wrist ready to break it, but suddenly he let go of him and hissed in pain grabbing his head.

In that moment Klaus noticed the blonde girl next to Damon, grinning showing her perfect teeth at him "And I hate how you old vampires are so cocky thinking they are the kings of the world when in reality are just spoiled children."

When she stopped the aneurism in his head, the Original walked at her giving a deadly glare but in response he didn't get anything just a smile, which made him angrier, she wasn't taking him seriously, just playing. Calmly he asked.

"And who you might be?" he asked intriguer.

"Oh, did Katerina didn't tell you who I was?" Cvilidreta asked innocently, then grinned "Oh, that's right she doesn't who I am" she licked her lips "Shame, I'll guess you'll never know."

"You little witch" Klaus hissed "You won't step in my plans."

"You think you can stop me?" she got up from her seat, looking directly into his eyes not caring from their closeness "Dearie, you may be steps ahead of them but it's because you know them, in this case I'm way overhead of you, I know who you are Klaus and you don't know a thing about me" Klaus narrowed his eyes "I mean if you know the enemy and know yourself, you need no fear the result of a hundred battles" she pursed her lips.

She leaned closer to his ear "Now tell me, dearie, what do you know?"

Cvilidreta backed away smirking she left his side, calling Damon and Alaric, the three left the grill, Damon laughed when he saw Klaus paralyzed in his spot. Till the moment they would be far away from him the Original would move again.

"That was fun" Damon said chuckling "I'm starting to like you more."

"Don't get use to" she said "You know what to do next?" she asked the vampire who nodded in response.

"Kill the werewolf to "ruin" the sacrifice" he said making quotes in "ruin" knowing the sacrifice had to happen or the deal would break and Elena will definitely died.

"Well it looks like you are not just a pretty face" she teased, she turned at the hunter "Help him, Alaric, I know he will need it" he nodded. Smiling the Dark One snapped her fingers and disappeared. Alaric blinked a few times at the event.

"Did she just..?" he asked his friend.

"Yep" Damon said making sound the "p" "She does that a lot" he shrugged "Come on, I need you to let me in into your apartment; Katherine will know where the werewolf is."


Katherine Pierce was looking for a blood bag in the fridge. She heard the key in the lock. She went in front of the door. It was Alaric.

"Look who's dumb enough to come back" Katherine said.

"Well, somebody had to invite him in" Alaric looked behind him "Damon. Would you like to, uh, come in?" Damon came in and she rushed over him.

"Are you trying to get me killed?" Katherine hissed angry. He pushed her against the wall.

"I gave you vervain, now I'm here to collect. I got it from here, Rick" Damon told.

"You sure?" Alaric asked him not sure of his friend's words.

"Yeah, only one of us needs to get blamed for this" Damon replied "Get back in the house. Keep Elena from handing herself over" he said following the plan, he and Alaric had worked up.

"Okay" he said understanding and left. Katherine looked at the vampire confused.

"Get blamed for what?" she asked him.

Damon clapped his hands pursing his lips "I need to know where Klaus is keeping his werewolf."

"Why? What are you going to do?" the older vampire asked crossing her arms.

"Dead werewolf equals no ritual" he said to her.

"No" she shook her head "You can't interfere, Damon. Klaus will kill you and everyone you've ever met."

"I just need to delay this thing" Damon replied.

"No" Katherine repeated shaking her head "No way."

Damon sighed "You should like this. It's going to buy another month of your pathetic life."

"Right" she said smirking "Except that I'm not the vampire he's planning on sacrificing."

"What?" Damon asked confused, that wasn't part of the plan.

"Yeah. He's got Caroline Forbes and Tyler Lockwood" Katherine told him still with her arms closed "Therefore, I'm in the clear."

"And where'd he get that idea from?" he said pushing her against the wall.

"Hey" she yelled "Hey, hey, hey, I'm just trying to stay alive long enough to get myself out of here."

"What if I told you Elena had vampire blood in her system?" Damon said getting back to the lie.

"What?" Katherine asked in disbelief.

Damon smirked "Imagine how much fun that will be competing with Elena for Stefan's love for, I don't know, forever."

"The tomb" she sighed defeated "He's got them in the tomb."

"Thank you" Damon said to then leave.


The Dark One opened her eyes grinning like the Cheshire cat, she heard Damon and Katerina's conversation, things were getting more complicated for them but for her, the fun was just starting; they all were exactly where she wanted.

Klaus frustrated and getting desperate to start the sacrifice thanks to her sudden presence; Katerina nervous of what was going to happen thanks to telling Damon where Tyler and Caroline were, who knows what Klaus would do to her if he knew it was her who spilled everything to the young vampire; Damon running to "ruin" Klaus plans which would lead to him a bite from Tyler Lockwood making Stefan want a deal with her to save him; Elena would also lost her aunt Jenna by Klaus' hands gaining another deal in which the doppelganger would ask her to bring her back; she wasn't worried about Elijah and Bonnie, easily she could take Bonnie's magic any minute and Elijah it was obvious he would help Klaus when the hybrid tells him about how he didn't kill their siblings.

"After centuries of boredom, finally I have some entertainment" the Dark One said jumping and clapping her hands happily. And no one was going to take the fun away from her.
