Summary: Humanity has fought a secret war against the forces of darkness since the beginning of time. A Council of men (and then women) vowed to watch over and protect the Earth for as long as demonkind existed alongside humanity. Much has changed and yet so little has; Earth has advanced so rapidly within the last few thousand years that it is now almost unrecognizable but there is still much to learn, for the people of Earth are still so young in comparison to the other races (or so it is believed). Medicine and Science are the new religion—but bigotry, prejudice and fear of the unknown still remain in the hearts of men.

"I have never advocated war except as a means of peace."

Chapter Summary: How the world of the Vampire Slayer could, in any way, relate to the future that is Captain Jim Kirk's reality.

In a historic moment, the Captains and Soldiers of Good and Evil met on the battlefield, not to fight, but to negotiate on their own terms how to end this futile War. Over the site of the sunken town that was once known as Sunnydale, two forces met as different as Night and Day and bound only by their Hatred of each other: Buffy and Faith, newly-crowned Queens of the Slayer Bloodline led the "Good" side and Eve and Lindsey, daughter of the Senior Partners and her consort, a powerful (and evil) lawyer in his own right, led the "Evil" side.

For endless moments, they merely stared across the battlefield, wondering, considering whether they were really going to do this. If they succeeded, the War would be over at last and one side would rule till the end of Time and Beyond. If they failed, no one would survive the backlash, forever erased from living memory and cast into Oblivion.

Faith, no less bold than she was years ago, was the first to speak.

"Well, did we come here to make a deal or not?"

Elegantly clad in a crisp suit of dark blue, Lindsey McDonald answered: "Exactly what I was about to say, Miss Lehaine. Let's get down to business shall we?"

She threw her head back and laughed.

"Oh? And here I thought we were here for business, not business…" Faith trailed off with a suggestive smirk.

He gave her an answering smirk.

The woman who stood beside him narrowed her eyes in anger; the Slayer had made advances against her consort.

"Enough."

Faith watched as her Sister-Slayer and Queen walked to stand beside her.

"We have wasted time and we all know we could be interrupted at any time by them, so let's not waste this chance and get down to business." Buffy looked around at everyone. "I'm sure I'm not alone when I say I'm tired of this stupid, endless war. It's time we end this once and for all. Question is: How are we going do that and without them finding out?"

Eve hissed, turning her anger at her consort and Faith on Buffy.

"I thought you had something to offer, Slayer, or else, what is the point of this meeting?"

Buffy looked her in the eyes, unflinching.

"Do you have something to offer us, then?" She said, knowing the answer even as she asked.

Why else would either of them be here, if they already had the answers they were looking for? Both had come here hoping to find a solution and had even agreed to a temporary truce to do so—if that didn't prove how serious they both were—and were willing to work together when their usual modus operundi was to kill each other on sight.

The hesitation was all the answer she needed.

"I didn't think so."

She turned to address the crowd once again. "We're all here and agreed to a momentary truce, let's use our time wisely and do what our predecessors couldn't before and end this."

Pale skin glowing under the full moon's light, the Red Witch spoke: "Some kind of spell, maybe? Though there'd have to be a huge (and almost always) bloody sacrifice."

Almost immediately, she was pitted against a rival mage, as old and withered as only one who's lived hundreds of years could be. "Are you a fool? No mere spell could ever hope to achieve what we are proposing! The power it would take…"

And so they began, arguing and shouting and cursing at each other, back and forth, back and forth; either it was too great a sacrifice (the Scoobies weren't too keen on sacrificing a bunch of babies just to get out of a fight) or the chances of surviving were too little (no one on the others side were too keen to sacrifice themselves either, they weren't martyrs like the "good guys" after all).

They didn't get anything done that night. Or the next. And not the one after that either. But on the fourth night, the very last night the enchantments they had weaved would stand strong against the eyes of those watching from above and below—on that night, the answer was found.

"A deal. Goddess, that's perfect! Buffy, let's make a deal with them."

Buffy frowned at Willow.

"What? Willow, what are you saying—"

"Let's make a bet between our side and theirs; if they win, they can have the Earth and do whatever they want. But if we win, they leave—forever."

Xander snorted.

"…that's crazy talk, Will."

"No, Xander, hear me out—"

She tried to say, but he talked over her, resolutely listing all the reasons why it was a bad idea.

"First of all, they'd never agree to anything that might end with them losing—"

"But that's only if—"

She tried again.

"Second of all, what kind of lame bet is that? If we lost, we're done for. They'd hunt us down, make shiskabobs out of us and eat us for dinner."

"Xander—"

"Or make us their butt-monkeys and I promised myself that'd never happen aga—"

Fianlly, she used her magic to amplify her voice: "ALEXANDER LAVELLE HARRIS, WILL YOU BE QUIET AND LISTEN TO ME?"

He raised his brow, looking around meaningfully and especially toward the other side.

"…I think we're all listening to you now, Will."

Murmuring rose from the demons and creatures under Eve's command.

"What'd the human say?"

Interested despite herself and bored, Eve shouted over the noise, "Hey, Rosenberg! Why don't you share with the rest of the class?"

Willow nodded satisfied, as if that had been her plan all along.

"Good. Everyone should hear this. Guys, girls—demons and evil lawyers—I think I have the answer."

The Red Witch proposed this: gamble on Humanity, give them a certain amount of time to advance as a civilization and if they destroy themselves in the process, either through War or natural disaster, so be it and the Darkness would return to a world they could conquer with ease. But if Humanity should endure till the end, meet them in battle and win….then the Darkness would willingly bind themselves to an immortal vow of exile, never to return to Earth ever again. And the Earth would finally, rightfully belong to Humanity for all Time and Beyond.

There was a price, of course, and it was this: that the forces of Darkness, in order to allow Humanity to grow, would leave the Earth for the, as of yet undecided, number of years to another dimension or reality, wherever they wished, so long as it was of a sufficient distance from the Earth, that no one on Earth would ever be able to reach it either by design or accident and that they would bar the way behind.

For the Slayer and her People, the price was this: to make a promise, bound by the Old Magicks, that they would not interfere, by word or deed or premonition, even should Humanity be on the brink of destruction—and this was the gamble, the risk, the Red Witch asked of them to take—by willingly entering into an enchanted sleep and sealed deep within the Earth, until War beckoned them to rise once again.

And there were concessions and compromises that were made, aside from the price each side were asked to pay, of course, because as much as they despised the struggle, it was just as much a part of their nature.

The Slayer, after conferring with her Council and at the urging of her Watcher, requested an exception be made for the Demons who wished to stay on Earth and were willing to work with her People or had children who were half-human. The Daughter of Darkness, in turn, demanded every immortal soul that had committed evil as soldiers in her army or as food for her demonic allies and followers, depending on how useful they turned out to be.

For some time their pettiness kept them all occupied but finally, calmer heads ruled and certain concessions were made.

The Daughter of Darkness could have her souls, but only if those souls were the most evil of them all or willfully signed away their souls to Her: The Slayer was allowed her demonic allies and for any half-blood children to be under her protection (and law), but only if the Elders of those demonic Clans were willing to join them in their enchanted sleep. Understandably, this caused some friction between the two sides and even among their own forces.

But the compromises were as far as each side were willing to go and any further tension would cause too much strain on their fragile truce to stand for long, and so they agreed and now the only thing left was how much time they would have to wait. This caused another argument, but one, thankfully, much more academic in nature as each side put forth the number of millennia that would be necessary for Humanity to, theoretically, progress enough to stand on its own. Finally, it was decided by all that 3,000 years would be enough (hopefully).

The Slayer Queens and their Council and the Daughter of Darkness, along with her Consort and her Generals spilled their blood into a ceremonial bowl as their faithful Witch and Mage, respectively, chanted around them, their Magic touching for brief moments of dazzling beauty, as Dark and Light, Earth Magic and Demonic, mixing together to form an impenetrable barrier around them, as at last, the Ones Above and Below found them and realized what was about to happen.

If the two sides should make the vow, through them, as they were connected to their Masters, the deal would be as binding on them as it was on their mortal (and immortal) Champions. The Ones Above and Below threw all their might against the barrier, but as it was their own magic being used against them, loosely speaking, and that the Castors were not any old spell-castor, they were unable to pass through or do any kind of damage—for now—but they were Old and Powerful and would get through sooner or later. Knowing this, the Circle made haste and joined hands, their blood mixing and binding them, and made their promise for all to hear.

Ancient magic wrapped around them like vines and carved that promise into their very bones.

The ground beneath them churned like the raging ocean and marked where they stood.

The Ones Above and Below screamed in rage and fear, outwitted by their own pawns.

When the barrier fell and the Circle was broken, the Slayer Queens and the Daughter of Darkness likewise fell onto their knees, shaking and pale.

There was deadly silence for a moment and then—the Witch held up the roll of parchment where once a ceramic bowl inscribed with runes and filled with blood had once been—and a great cheer arose from all.

The deal was struck.

AN: for those who've read the previous version, what do you think of the rewrite? its only the prologue—and just the first of it, too! i realized i had made a mistake in starting from the middle and needed to set up the background unless i could think of clever ways to insert it into the narrative...which i tried before with the second chapter of the previosu version (whhich i had NOT published) and hated it. it was too obvious by half.

for those who haven't seen it and i don't think anyone has really, considering that i only got two reviews—thought they were very much appreciated, but then i haven't looked at the story stats so...maybe...anyway, tell me what you think of the beggining. did i make a creible-enough attempt at explaining how the worlds mix?

and don't worry, part 2 is coming right up!
