Chapter One: The Lord has Work for You

A dark purple Audi Quattro pulled up outside the graveyard. Its driver got out and went to the trunk. She was a twenty-six year old, with long, wavy dark brown hair and blue eyes which sparkled even in the darkness. For Alexa Summers this was a regular salt and burn job. Easy as pie, just get a few weapons (just in case of attack), gasoline, rock salt and a lighter or matches and *POOF* job done.

Tonight however, things were about to change.

She lit the bones, watching as the witch haunting Ashville, North Carolina finally was put to rest. Satisfied with her work, Alexa turned and headed back towards the car. She heard a flutter of wings and spun around. A man in a tan trenchcoat stood before her, wearing a dark suit with a white shirt and blue tie, his hair ruffled and out of place (so dark it could be mistaken for black) and his eyes beaming bright blue in the darkness surrounding them. He moved towards Alexa and backed her into a tree, covering her mouth with his hand.

"Do not fear me, Alexa …" he said, his voice so deep it made Alexa's ribcage tremor, "My name is Castiel, and I am an angel of the Lord."

Castiel studied Alexa's eyes, which darkened at how close he was to her. He gave her an intense stare, making the young hunter uncomfortable.

"Do you understand that I mean you no harm?" Castiel asked, Alexa nodding in response.

He gave her another look which flooded her with warmth. She felt safe and she felt she was able to trust Castiel. The angel removed his hand from the human's mouth and took a step back. His Grace buzzed around him like a whole different kind of electricity, and it was frighteningly beautiful.

"What do you want with me?" Alexa asked, trying not to show her fear to the being before her.

"The Lord has work for you." Castiel replied, his voice monotonic and his face expressionless.

"Sorry…the Lord has work for me?" Alexa asked, shocked but in a way honoured.

"Yes. You need to join forces with Sam and Dean Winchester. They are on their way to find you."

"What? Why? Why am I needed?" Alexa asked, terrified.

"You are a part of the Apocalypse which is due to loom over us if we don't prevent Lilith breaking the sixty-six seals. Unfortunately, Dean Winchester has already managed to break one." Castiel replied, Alexa staggering back to the tree, trying to keep her legs from buckling.

"What part do I play in the Apocalypse?"

"That I do not know at present." Castiel answered with a slight hint of annoyance in his voice, "But you must trust that what I speak of is true. Go back to your motel room and wait. Within the next couple of days Sam and Dean will arrive and no doubt Dean will be hostile. He doesn't trust things he doesn't know much about."

Alexa nodded in understanding.

"I guess I'll be seeing you then…" she said, sheepishly.

"Yes you will. Goodbye, Alexa."

"Bye, Castiel…"

Damn...what kind of weird-ass hunt did this turn out to be?
