~Chapter 1- Name

-1 week later-

A week after she walked into their lives, Dean sat looking at the sleeping woman as he and Sam poured over books, doing research trying to figure out what she was. "I just don't get it Sammy, a Harbinger is an Omen. So what is she?"

"Maybe we should call Cass, after all she said that he is her protector," Sam offered.

"No," Dean said sternly shaking his head. "Not until we get the whole story." Sam looked at him. "Dean, we have no idea what we are dealing with," he said matter-of-factly.

"Exactly and until we do, we don't call Cass."

"So what do we call her?" Sam asked looking at her. "We can't keep calling her Paws." Dean looked at his brother, a smile on his face. "Hey I thought that was cute."

"Dean."

"Fine, you think of a name."

Sam sat back in the old musty brown chair thinking, "How about Aurora?" Dean looked at the woman. The name fit, he had to admit that. "That's fine, it fits her. Now all we need to do is figure out whats going on."

"You're going to call me Aurora?" The woman asked looking at Sam and Dean. "Yes, that will be your name," Sam said with a smile.

"Okay, when can I see Castiel?" Aurora asked looking at the brothers expectantly.

Sam looked at Dean, letting him tackle the issue. "Not right now," the eldest Winchester said gently. "How come?" Aurora inquired, her gold gaze sad.

"He is busy…" Sam offered up hopeful.

"Sam. Dean."

Sam and Dean turned and saw the topic of their conversation standing behind them. Castiel looked at them for a moment then at the woman sitting on the edge of the bed fiddling with the hem of her shirt. Castiel walked over his blue gaze calculated. "Where did you find her?"

Dean looked at him a faint smile on his lips. "She found us."

"Cass what is she?" Sam asked leaning against the wall, looking at the Seraph. Aurora looked at Castiel as if he was God himself. "Castiel?"

Castiel looked at her and nodded, "Yes, what is your name?"

Aurora looked at him, "Sam and Dean call me Aurora." She jumped off the bed and hugged him, Castiel awkwardly wrapping his arms around her resting his chin on her head. "I've been looking for you for so long," Aurora cried.

Castiel looked at Sam and Dean. "She is a good Harbinger, the sign of the end of the Holy War."

"For which side?" Dean asked worried.

Castiel looked down at Aurora as she played with the belt to his coat, "Ours."

"So our side is going to win?" Sam said with a smile that held relief. "If Aurora is not killed," Castiel said. "To kill such a pure creature is blasphemous, she is of pure soul."

"Cass, she doesn't even know who she is." Sam responded confused.

"Of course a Harbinger is born with only one mission. It's rare if they know who they are," Castiel explained.

Aurora looked up at Castiel as he talked with the brothers. When she was born she knew who he was, what he looked like. She dreamt about him. In some ways she loved him…He was her protector. But a Harbingers kiss was fatal…unless it was true love…

Castiel looked down at his charge, she seemed tired. "Aurora do you need to sleep?" He asked.

"Yeah, but will you stay?" She asked taking his hand. Castiel looked at their hands, then back at her. "Sure."

Dean looked at Sam as Castiel led Aurora over to the bed and tucked her in."What was that?" Dean whispered. "Not a clue…." Sam shrugged.

Aurora lay under the blankets looking at Castiel, as he sat in a chair next to the bed. He wasn't going to say anything but he would sit there all night if he had to. He felt drawn to Aurora, but in a good way. Little did he know that him and the Winchesters were in for more than they bargained for…

~Next time in BFH~~

Aurora paused when her foot came down on an object, it crunched heavily under her weight. Aurora looked down and saw it was the remains of a little girl. A cold dread filled her. "Oh my God…"
