Unwelcome Visitors

Part One

Colonel Jack O'Neil leaned back in his chair, hands clasped behind his head, absently listening to the briefing flowing around him. His teammates were ranged around the long table, each of them curious about their upcoming mission. Daniel sat leaning forward, listening intently to General Hammond, Sam was obviously doing calculations in her head as she riffled through the folders in front of her. And Tealc - well he was always ready, even if they didn't know what for yet. Jack pushed back in his chair, nearly overbalancing as Hammond came to the crux of the briefing.

"Whoa, general - say what are living all over the world"

General Hammond straightened, stern, flinty eyes locking with Jacks disbelieving brown ones.

"Just what I said colonel, vampires, witches, werewolves. all manner of demons"

Jacks eyebrows rose up a little higher as he just barely caught himself from falling onto the floor. He righted his chair nochantly before coolly looking around, as if he hadn't just almost fallen over.

"You're kidding, aren't you? It's April Fools Day or something, cause that's just about the craziest thing I've ever heard"

Jack was stunned, * he can't be serious *, he looked helplessly at Daniel

*Oh that was so not a good idea *, because Daniel launched immediately into lecture mode. He stumbled over the words at first, dark blonde hair falling into his eyes, his hands gesturing in time with the rise and fall of his voice.

" There is evidence in all the writings of the ancient and modern world pointing to the existence of otherworldly creatures."

Daniel's glance skipped around his audience nervously, not wanting to settle on anyone, well on one person in particular. It was times like this when he didn't want to fall into the trap of looking at Jack, didn't want Jack to see something in his eyes, something that would cause...questions. Swallowing down his flare of attraction for his commanding officer Daniel focused on what he knew.

"Monsters we believed to be fictitious could have actual basis in fact. Stories of witches and warlocks have numerous mentions in nearly all cultures, seers and sages, even fairies have a place in mythology."

Daniel plunged on disregarding the stark disbelief in Jacks eyes, Sam listened intently and Teal'c merely arched an eyebrow possibly in agreement, it was hard to tell with him.

" Some of the creatures we've fought could be considered demons in this world .. and then there's the Goa'uld. They are the ultimate demon, god knows how many more myths they have spawned."

Teal'cs deep voice rumbled ominously in the silence of the room.

"Daniel Jackson is correct, the oonass alone would inspire many legends among your people."

"Teal'c"

Jack whined in protest as the Jaffa regarded him with that annoyingly steady gaze, he paused mouth open and then closed it, carefully leaning back in his chair. He took a breath and phrased the question he knew he was going to be sorry he asked,

"So what are we going to do"

General Hammond let out the breath he'd been holding, he knew Jack wouldn't want to believe this.

* Hell it goes against everything I believe in myself *.

"Major Carter, if you please"

Sam knew how Jack felt but there really was no other explanation that she could scientifically see. "While testing some new equipment I've been developing, I came across some unbelievable things. The detector I designed started picking up strong evidence of paranormal activity, hotspots if you will, places where the energy literally surges from the earth. I found one of the strongest hotspots in California a small town called Sunnydale, while I was cross- referencing the co - ordinates a red flag appeared on my terminal. I had the necessary clearance and was able to access files on a secret military base that was built there a couple of years ago."

"I don't understand, if there is already a base there, what is this to us?"

He grimaced as Sam's enthusiasm went up a notch.

"There's no base there now. It was destroyed a year ago, among the personnel missing was the director a civilian...a Dr Maggie Walsh."

Daniel looked surprised, he stuttered a little - something he hadn't done for a long time and blinked rapidly.

"I..I knew Maggie at university, I didn't realise that she worked for the military too"

Sam reached over and squeezed his hand briefly while Jack cleared his throat awkwardly covering his reaction to the tearful glints in Daniels eyes.

"So what else did you find in the files Sam"

"Colonel O'Neil, the base was called the Initiative, they were organised to gather information about that hotspot and to control the demon population of Sunnydale."

"Demon population?"

Jack arched his eyebrows, he watched as Daniel hung his head, momentarily distracted by the younger mans pain.

"Yes Sir, demons captured were 59 at the last count before the base was destroyed. 45 of those were vampires, the rest were assorted demon types."

General Hammond broke in, aware that Jack was becoming restless.

"How was the base destroyed Major Carter?"

Sam consulted her notes glancing around the room as she continued

"Dr Walsh was working on several projects but we believe one, the Adam project backfired."

Jack couldn't help the sarcasm that dripped from his question

"Adam project Sam?"

Seeing General Hammond nodding at her, Sam continued.

"Dr Walsh created a monster, like the old Frankenstein movies, except she used demon parts to graft onto a human body. Unfortunately for her it worked, she made Adam too strong and he destroyed the base and most of the personnel."

Jack sighed and running his fingers through his sandy hair in a tired move.

"This just keeps getting better and better. So we have a crazy patchwork demon loose in Sunnydale, California do we?"

"Uhh no sir, Adam was destroyed. According to an agent Finn who was a survivor, he was taken down by "the Slayer"".

Jacks eyes widened "By the .. did you say slayer"

Jack jumped as Daniel broke in excitedly, he'd thought the young archaeologist had been thinking of his own pain but there he was.. his beautiful eyes closed in concentration.

Jack nearly groaned aloud * beautiful..oh my god..*

Daniel searched his memory, his fingers leafing through invisible books.

*soft fingers ..just right for ...dammit ..down Jack ...we're in a god dammed fucking briefing..oh yeah down is good..arrrgggh .. not thinking not thinking not thinking* . "I've heard of that name before, I remember reading a journal about the slayers .The Slayer is the Chosen one, a human girl with the power to slay vampires and demons. Gifted with extraordinary strength and agility, apparently she has a pretty short life span because of her work and when she dies another is chosen."

Jack sucked in a steadying breath, aware that his teammates were giving him some strange looks.

"Now this is all very interesting, but what has it got to do with us?"

General Hammond sighed, taking command of the briefing again he gave his orders

"Colonel O'Neil we have had information from the Tokra that the Goa'uld system lords are interested in the kind of energy we have detected. Also that they have expressed an interest in vampires "

Jack scoffed "And that would be bad because .... their just demons right"

"Wrong" General Hammond thundered," they are citizens of this planet and deserve our protection"

Daniel twirled a pencil around in his fingers "Why would they want a vampire, from what I've read of Vampires they are humans who have a demon in possession of their body. If a Goa'uld were too take over a vampire it would effectively have to overpower the demon yet still keep it caged within. Vampires are supposed to be a lot stronger than humans, with resistance to diseases since the human they take over is effectively dead, yet they retain all their memories and are immortal."

"So why would the Goa'uld want with them, they are immortal anyway"

"They are to a point Jack but they only increase the strength of the host to a certain point."

"Vampires may have extra senses that humans don't, that would be an asset to the Goa'uld" Teal'cs mellow voice paused "It occurs to me that from what you have said, that vampires and the Goa'uld are remarkably similar and that to merge two such creatures may create a stronger Goa'uld."

"It is also possible that the Goa'uld would wish to use these vampires as one would use a pawn."

The stillness of the room was broken by General Hammond's voice

"Perhaps it would be wise for us to find out more about these vampires, Major Carter do we have any sources left to exploit"

Sam flipped open the top folder, shuffling the pages until she found the one she wanted.

"Agent Finn recommended a Rupert Giles, his background check has interesting gaps. He's English, highly educated, has several degrees yet there are gaps of years in some places. He apparently was the librarian at the Sunnydale High School, before it was destroyed and now runs a thriving business called the Magic Box. The strangest thing agent Finn said was that he was the Slayer's Watcher, whatever that is?"

Jack shrugged, this whole thing sounded strange to him, the sooner it was over the better, he hated waiting around.

"Okay people, General Hammond permission to recon Sunnydale and to gather intelligence concerning the energy source and the.. umm Vampires, I don't believe I'm saying this"

Hammond smiled slightly before his face quickly returned to his normal stern countenance

"Permission granted Colonel O'Neil, Major Carter take whatever equipment you need and establish a base of operations. I think it might be better to keep this low key, the military still has several properties there, former accommodations for base personnel. You can take over one of them for this mission. Make no mistake Colonel O'Neil, this has top priority, be on your guard and take care, all of you"

Jack stood and saluted smiling at the general as he swept his hand down and in front of him ushering the rest of the team toward the door.

"No sweat Sir, we'll keep in touch"
