Part one.

"It is not known precisely where angels dwell - whether in the air, the void, or the planets. It has not been God's pleasure that we should be informed of their abode."- Voltaire

"Oh come on." Addison muttered under her breath as a light over the table she was folding clothes at burnt out.

Her light green eyes looked around the laundry room in her apartment building, lately she hadn't been able to shake the feeling that she was being watched.

Pulling her dark brown hair back into a loose pony tail, she glanced down the old hallway and tried to ignore the feeling.

Holding up one of her favorite shirts, she frowned as she saw a paint stain didn't come out in the wash, frustrated she tossed it in the basket and jumped when she saw someone standing in the room with her.

The man looked at her with blue eyes that seemed to read right into her soul, he had very dark brown hair that almost looked black in the now dim lighting. She looked him up and down, he was in a business suit with a long tan trench coat over it, she felt uneasy when she saw he didn't have a basket of clothes.

Trying to appear casual she started putting her clothes back in her basket without folding them, just wanting to get back into the safety of her apartment and lock the door behind her.

"You're Addison Pennant." The man said as he took a step towards her.

Her heart pounded in her chest, as she looked at him wide eyed. This was the same man who had been haunting her dreams for a few months now.

"Who are you?" She asked, her voice shaky.

"I'm Castiel." He responded, almost as if that should mean something to her.

"Stay back!" She hissed as he took another step towards her.

He stopped and cocked his head to the side, his eyes searching her face.

"What do you want?" She asked, as she eyed the open door to the laundry room, trying to decide if she'd have a chance of running past him.

"I am supposed to keep you safe, you are in my charge now." He responded.

"I have to go." She said, feeling more scared than before as she grabbed her clothes basket and headed down the hall to her apartment, thankful to have gotten away from the man.

"See you tomorrow." Addison said to a co-worker as she walked out of the book store she had worked at for the past two years.

Getting into her blue Prius, she stopped at a local craft store to pick up some more paint and paint brushes before heading back to her tiny apartment in a historic part of Indianapolis, Indiana.

Pouring herself a glass of wine, she turned on some soft music as she stood in front of the canvas set on an easel in front of an exposed brick wall.

Almost as if in a trance she began to paint a portrait of the man she had been dreaming about, she had almost convinced herself the meeting in the laundry room was a dream too, it just wasn't possible.

Taking a sip of her glass of wine, and mixing several hues of blue, she smiled to herself as she felt she had created the exact shade of blue for his eyes.

After finishing the painting she stood back and looked at it, proud of herself for the quality of the art, but disappointed that it was of the same subject as the last ten. She just couldn't get him out of her head.

Laying down in her bed, she pulled her black and white zebra print comforter up to her chin and snuggled into her fluffy pillows as she listened to sounds of traffic and car alarms through her window.

She was almost asleep when she heard the aged wooden floor creak in her living room as if someone was walking across it.

Sitting up in her bed she listened closely for any sounds of movement, her heart raced with fear as she heard another footstep.

"Shit, shit, shit." She breathed out as she realized her cell phone was charging in the kitchen.

The footsteps got louder as they neared her bedroom, she pulled the blankets up over the bed trying to make it look like no one had been sleeping there, and tip-toed over to her closet.

"I thought you said she was home." A male voice said.

"She is, I watched her leave work and come here… she never left the apartment after that." Another male voice answered.

"If you say so." The first voice said.

"She's in here, she has to be." The second of the two said.

Putting both hands over her mouth and nose, she hoped they wouldn't be able to hear her shaky breathing as she closed her eyes and prayed these men would take what they wanted and leave her alone.

The room was quiet for a about a minute, and she wondered if they had left then the closet door flew open.

"Found her." A tall man with a shaved head said, as he looked at her with coal black eyes.

Before she could scream or say anything, he grabbed her. placing a hand over her mouth as she struggled against his grip, but he was stronger than he looked.

She had seen plenty of crime shows on TV and she knew her best chance at staying alive was to get the hell out of there, if they managed to abduct her it was almost a sure thing they would kill her.

Mustering all of her strength she bit down on his hand as hard as she could, he yelled in pain and let go of her.

"You're gonna pay for that bitch!" He growled, as the blackness fully took over his eyes.

"Oh my god!" She yelled as the man in the trenchant appeared in the room behind the man.

She watched in complete shock as the trench coated man put his hands on the kidnappers head, within seconds blinding beams of light came from his eyes and mouth as he died.

"Oh man!" The other kidnapper said as he titled his head back, and a low roar sounded as a thick cloud of black smoke flew from the man's mouth.

She put a hand over her stomach as she felt sick.

"Are you alright?" Castiel asked her.

"I… They… Oh my god." She said, shaking her head.

Looking around the room he said, "We have to go, more are on their way."

"More what?" She asked confused and not sure if he had been in on the whole thing.

"Demons." Castiel responded.

"Demons? What the hell are you talking about? What would they want with me?" She gasped, taking a few steps back from him.

"You. Addison, you are a descendant of the Nephilim." He responded.

"The what?" She asked, her head was spinning.

"We have to go." He said, his voice dry as he spoke.

"I'm calling the police." She said as she turned and started out of her bedroom, stopping abruptly as Castiel appeared in front of her.

"What are you…?" She started to ask as he reached two fingers out and placed them on her forehead.

Everything instantly went black for her.
