Author's note: This is the brainchild of my evil muse, Demoncat. I have worked on this story exclusively for several days, ignoring my other work in favor of getting this beauty started. I had to admit that it was a good idea, and once I got into it, the plot trapped me. So here's the prologue. I have this and four chapters complete at this point, just not typed, so you won't have to worry about me falling behind on this one, at least for some time.

This is very AU, for both universes. Everything up to "Graduation Day, P2" happened except that we changed the ending. I've played merry havoc with the facts in SG-1, so take nothing for granted. Daniel does not "ascend" in this story. Jonas never happened. And the other changes will make themselves known to you as the story unfolds.

Enjoy!

MAY, 1999, GRADUATION CEREMONY, SUNNYDALE HIGHSCHOOL

The Mayor had started his speech, and it had promised to be a long one. They had already known that the man was evil, but this was even worse. Buffy wished that the orbits would just hurry up and converge so she could get to the exciting part. It might seem callous or shallow, but it was more the fact that, not only did she hate waiting, but she hated listening to long speeches. She just wanted everything to get to the point where she could kill the demon.

Then it happened, and there were vampires and armed students everywhere. There was the giant demonic snake that the Mayor had become. And there was Buffy, Vampire Slayer, running through the halls, leading said demon snake on a merry chase through the halls of Sunnydale High toward a massive bomb. A bomb situated directly on top of the local Boca del Inferno, the Hellmouth to most people.

Until that point, all had gone as planned, but random chance threw its lot in with Fate and the course of this little universe's plot was altered forever. The Slayer tripped on a stack of books that wasn't supposed to be there.

With the C4, the mystical esscence of the Hellmouth and the demon's flesh, the result would never have been so catastrophic, and could have been attributed to a ruptured gas main. But thrown into that volatile mix was one of the most powerful and ancient demonic esscences that had ever graced that dimension. The Slayer.

All Hellmouths on Earth reached into the same Hell, though there are countless others in all the vast multiverse, and with the explosion in one of them, the entire Hell dimension collapsed, creating a destabilization in the Earth's crust as hundreds of other Hellmouths all over the planet began to explode. A chain reaction had been started. Not long afterwards, Earth sunk into the vacuum left by the destroyed Hell. The moon soon followed, and then Mars, Venus and other rocky bodies throughout the system, until finally the sun itself was doomed to fall into the immensely predatory gravity sink. Eventually, that entire universe will fall into it, only to be reborn in a billion years or so. Even chaos takes time, but the end is certain.

But all was not lost. Instead of dying, as perhaps she should have, in the death of her universe, Buffy Summers was caught in limbo by a powerful, ancient being. This was a creature who knew and could manipulate the multiverse. He was neither god nor devil, but a servant of something much larger than those things, while being of less intelligence than a human child. It could handle simple tasks of cognition, but it could make mistakes, and one of those mistakes had caused those books to be left in Buffy's path. So, feeling responsible, it took hold of her and preserved her whole, with the added life span of a thousand generations. She could do everything she could before. She was still a Slayer. Only now she would live long enough to see and do anything she could possibly want before she died.

He sat her down gently on the surface of a new world, touched her face gently, and then left her to wake naturally on the desert sands of Chulak.

And that's the prologue. Don't worry about our little Monolith character. You won't ever see him again. He's just a plot device.
