Prologue

"It's always gotta be the blood"

He watched as the slayer finally made her way to the top of the tower. The funny little guy that had just thrown the bleached vampire over the edge seemed be looking forward to fighting her. Seeing as he had just cut up the slayer's kid sister, Whistler really wouldn't want to be in his shoe…

Huh. She'd just pushed him of the tower with barely a glance. The balance demon would have laughed at that had he not known what had happened to the blond this past year. What would have happened after this. And what was going to happen.

"Summers blood"

Army boy decided to pay to become vampire chow, blaming it on her being distant, and then giving the slayer an ultimatum and finally leaving town. Little sis turned out not to be her kid sister but a big glowing ball of energy, that had the power to destroy worlds and was coveted by an insane hell goddess. Then dear old mom kicks the bucket.

Add to that slayer duty and a stalking vampire, it would be enough to make anyone crack. It was enough to make Whistler feel sorry for her.

And then there was that little surprise the Powers had in store for her.

"The monks made her out of me"

If the Powers did nothing, what would have happened was that the slayer would have died, and therefore, restored order to this world. It was not meant to have two slayers.

Unfortunately the redheaded witch would then get it into her head that she could screw around with the natural order, and bring her best friend back to life. This would be bad on several levels. First the slayer would be stripped of her reward, namely peace. And that kind of trauma scars the soul. Second it would completely screw up the Balance between good and evil, because it would create a loophole for the First, and ultimately force the slayer to awaken all of the potentials. The amount of evil that would have to be unleashed to restore the Balance was mind-blowing. So the Powers decided to do something about it.

They decided to send her somewhere. Somewhere out of the witch's reach. An alternate world that only had human champions and a war about to break out. A place that could definitely use the help of the longest living slayer.

He felt sorry for the poor bastard who had to deliver the message of her new assignment.

Oh, it was almost time. The slayer was currently leading her injured little sister away from the edge of the tower, but it was already too late. The blood had started to flow, the portal already opening, and the only way to stop it was to make the blood stop flowing.

The slayer didn't seem to want to accept this and kept walking, but there was no way she didn't feel that spark. Finally the kid made her stop, and they started arguing.

Whistler could pinpoint the exact moment when it all clicked for the slayer.

"Death is your gift"

He watched as she gave her speech to the kid, and hoped she could follow her own advice about living.

And there was the swan-dive. Whistler had to hand it to her, she was graceful, but then again most slayers were. He winced at the amount of pain he saw in her face, but it would be over soon.

There. She did it. The world was safe once again.

Little sis slowly made her way down the tower and arrived at the sight of the 'Scooby gang' surrounding the broken body of her sister.

He'd give them time to grieve, but then he would do what he came to do. He'd tell them to leave the slayer be, that she was in a better place and not to be disturbed. Not that they could reach her even if they wanted to.

They'd eventually get the dark slayer out of 'retirement' and move on with their lives. They were a strong bunch, the slayer had taught them well.

"Good luck, kid" Whistler said, before he turned around and walked away.

A/N: I know 'Buffy going through the portal and ending up in a different world'-thing has been done to death, but I wanted to take a crack at it anyway.
Anyway it's my first story so let me know what you think.
