A Fine Line

Chapter 1

Emma opened her eyes to find herself on the forest floor. Last thing she remembered, she had sacrificed herself for Regina and had become the new Dark One. The woman sat up and looked around, trying to figure out where she was. Definitely not Storybrooke. "Lost, dear?"

Emma shielded her eyes from the sun to see Regina standing before her. Only it wasn't Regina. Not her Regina anyway. The woman was dressed in lavish red and black velvet, her hair swept up in a tight bun. Her makeup was dark like the look on her face. "Regina." Emma sputtered, unable to tear her eyes away.

"That is a bit informal, wouldn't you think?" Regina snapped. That's when Emma realized that she must be in the Enchanted Forest before the curse that sent everyone to Storybrooke. The Queen forced Emma to her feet with the flick of her wrist, an invisible hand wrapping around her throat. "Who are you?" She hissed.

Emma gasped for air, her eyes widening. Her hand reached up to try and free herself from the Queen's grasp and suddenly she was released. As she fell to the ground, Regina was thrown a few feet back. Emma stared at her hands in wonder. She had never had that strong of magic. It must be the darkness that had consumed her. "Guards!" Regina yelled.

Two men hoisted Emma up, while another held a dagger to her throat. "Bring her to the castle." Regina glared at the younger woman before climbing into the carriage. Once they reached the castle, the guards took her to the Queen's quarters. "Leave us be." Regina ordered. The men shoved Emma to the floor and her knees hit the marble painfully.

"You have magic. Dark magic. There is only two people that I know of that possess such great power, and I am one of them." The Queen eyed Emma carefully. The Dark One glanced over to the floor length mirror, surprised at how much her appearance had changed. Her hair was a very light blonde, practically white and it was pulled into a tight bun at the back of her head. She was dressed head to toe in black leather, her lips stained a deep red.

The Queen jerked her chin towards her painfully, capturing Emma's attention once more. Emma's eyes flicked down to the low cut dress before her, and she couldn't help but notice the Queen wasn't wearing a bra. "Kinky. No wonder her guards listen so well." Emma thought. Immediately, she tore her eyes away from the sight and met the brown eyes studying her carefully.

She had never had a sexual thought about Regina like that before. They were best friends, and they were completely happy in their own relationships. "Are you though?" The little voice in her head wondered. Emma pushed the thought away. It must be the dark magic that was making her like this.

"Who are you?" The Queen demanded. Emma felt a smirk slowly creep onto her face. "I'm your worst nightmare." She answered, throwing the older woman across the room with her magic. Regina quickly recovered, furious. "How dare you treat me like this! I am a queen!" Her hand lit up with a fireball, and she threw it towards the blonde.

Emma quickly dissipated it into thin air. She grinned as Regina's eyes widened. The big bad Queen was afraid of a little Swan. "If you think Rumpelstiltskin's bad, I'm a hundred times worse." The younger woman sauntered a little too close to comfort, and Regina backed away slowly. "I can have you killed with one word." The Queen threatened. It came out as a frightened whisper.

"I'd like to see you try." Emma challenged. "Guards!" Regina shrieked. Two men burst into the room but before they could do anything, the Dark One killed them with a flick of her wrist and a sickening crack as their lifeless bodies fell to the ground. "Now tell me, your majesty- "Emma pointed to the guards. "Do you honestly think your mortal knights can defeat me?"

Suddenly, Regina lunged forward and pressed her mouth against hers. Surprised, Emma let down her guard for just a second. That one second was enough for the Queen to rip her heart out and grab the object in her pocket. They both gasped in surprise as Regina held the Dark One dagger in her hands.

It was engraved with the words 'Emma Swan'. "You're the Dark One?" The older woman looked confused, but her lips curled into a wicked smile. "Well Emma Swan, now that I have your heart- "She gave it a light squeeze, causing Emma to double over in pain. "You are my property."

"Fuck you." Emma hissed. The Queen chuckled, squeezing her black heart even tighter. "Careful Miss Swan, you wouldn't want me to accidentally turn this into a pile of ash."

"I'm immortal. You can't kill me." The blonde snapped. Regina carefully grabbed a small box from the shelf behind her and put Emma's heart inside, sealing it with a blood-lock spell. She twirled the dagger in her hands, pressing lightly on her thumb until a pinprick of blood appeared. She then sucked the blood off, not breaking eye contact with her.

Emma gulped, feeling her knees go weak. How the hell can such a sexy person exist? "Don't underestimate me, Miss Swan. You have no idea what I am capable of." The older woman sashayed over, grabbing Emma's chin with a perfectly manicured hand. "You are no more immortal than my guards you just incapacitated. You just have more power. But from the looks of it, you hardly know how to use dark magic. And you couldn't have defeated Rumpelstiltskin too long ago, he and I just had a nice chat 2 days prior."

Emma raised her hand to attack her, but Regina held up the dagger in warning. "You are not to use magic on me or my guards in this castle. You are not to use it at all."

The command hit her like a ton of bricks, and her arm slowly returned to her side. Now she really was powerless, and if Rumpelstiltskin truly was gone she was trapped here with no way home. "We are going to have so much fun." Regina purred, running her hand down Emma's arm. "But for now, I have other matters to attend to."

A swirl of purple smoke engulfed the blonde, and she found herself in a prison cell in the dungeons. The woman sighed and sat down on the stone floor. Regina, one; Emma, zero.
