AUTHOR'S NOTE - Here is a multi chapter fic I have been working on for the past couple weeks. The Lyrics included in this first part are from a song called "Always" by Saliva - one of my favourite songs at the moment. I thought the lyrics were appropriate to where I wanted to take this.

I hope you enjoy the story ....

THE REASON I BREATHE

Am I your one and only desire

Am I the reason you breathe

Or am I the reason you cry?

PROLOGUE.

It all started with a dream ...

A dream of a place I didn't know, that I had never seen before, of a time long before I was even born.

I was walking barefoot through trees of green, following a winding path lazily, unhurried while the sounds of fighting echoed on the breezes.

I stopped; I turned, and saw him.

The horseman ... bearing down on me, on a steed of black ... his clothes were of black brocade shot through with silver thread, ripped in several places, bloody patches and raw skin showing through.

Without looking to see if the way behind me was safe, I ran, stumbling over a pumpkin left by the side of the path. I cowered upon the ground as the horsemen drew closer ... and I looked up where his head should have been, of which there was none ...

"NO HEAD!! NO HEAD! NO HEAD!" I moaned, unable to stop the swing of the headless horseman's blade as he struck ...

********************************************************

I sat up in bed with a scream, forming a name.

The name was SAM although I had no clue as to why I felt scared for the life of the youngest Winchester as Sam had made no appearance in my dream at all. Yet still I felt like his blood was on my hands ...

*********************************************************

I started at the familiar sounds of flapping wings, and the presence of Cas pushing on my senses.

I sat up in bed, to find Cas sitting on the edge of it, staring at me with soulful eyes and loving look, and I grinned at him, drawing him into a hug and kissing him gently.

"Long time no see, warrior!" I murmured into his neck.

"I've been fighting to stop another seal from being broken, Jen. I could not come before," Cas murmured back. "This time, we won, but I'm afraid that next time you may not be quite so lucky!"

"Another seal is about to be broken?" I asked him, sitting up straighter in my bed, to stare at the angel before me.

Castiel gave me one of his slow nods of assent, never taking his eyes from mine as he did so.

"Beware the horseman on the black steed, for he cometh, Jen. And look out for Sam - he is not safe and needs to be watched. Make sure you make the right decision, when the time comes - listen to your heart, not your head - all will be forgiven!" Cas said cryptically.

"Cas, I don't know what any of this means!" I told him.

"You will, soon enough, Jen, you will!" Castiel said, sadly, turning his puppy face onto mine again.

He leant into me again, planting a kiss on my forehead, and I knew no more, until the sun rose again in the sky ...
