A/U: Post Chosen

Pairing: Buffy/Dawn - Yes this is an incest pairing. If you don't like the pairing then my suggestions is to stop reading now. And please do not review stating you do not like the pairing. I have a zero tolerance policy when it comes to such reviews. I have had reviewers give me grief over the pairing in my Charmed: Another Halliwell. So if you review about the pairing, consider yourself banned from reviewing ever again.

Disclaimer: Joss Whedon owns Buffy the Vampire Slayer. CBS and Paramount Studios owns Star Trek.

Note: I am starting with First Contact because in the Star Trek Timeline the Zefram Cochrane and the flight of the Phoenix portion is before anything else in Star Trek. If I continue this series I will then head into Enterprise, followed by TOS, TNG, DS9 or Voyager and end with the other movies in that order.

Prologue

Dawn Summers sat in the hotel room she was sharing with Buffy, twiddling her thumbs. Her sister was busy taking a shower which left her time to her thoughts. Buffy had promised to show her the world and so far she had managed it. They had seen Paris, Rome, Tokyo, London. Now they were in Madrid. Dawn couldn't be happier to be traveling with Buffy. She remembered back when Buffy had promised to show her the world. It had been one of the best times of her life, to hear the praise from Buffy. As she waited for Buffy to get out of the shower so they could go to dinner for Dawn's birthday, something shocked her.

One moment nothing was in the room except her. The next moment a man stood there. Dawn's first instinct was to yell for … "Buffy!"

"She cannot hear you," the man said. "For at this moment you and us are outside time. Or from our perspective time is frozen."

"You froze time?" Dawn asked as she backed toward the bathroom door. "Buffy, if you can hear me, get out here."

The man sighed. "Would it help you if she was here?"

"Yes," Dawn replied.

The man waved his arm. "Call for her."

"Buffy?" Dawn said.

"What is it?" came Buffy's voice from the bathroom.

"Put on a robe, please and come out here," Dawn replied. "There is a strange guy out here who can somehow supposedly freeze time."

A second later Buffy emerged from the bathroom, her hair still wet. She looked at the man and frowned. This was why she hated hotel rooms. Because vampires could come in. "How did he get in here?" she asked Dawn.

"By magic my dear," the man said. "We are Fate."

Dawn laughed. "Fate is a woman who houses the souls or spirits of three women."

"You are referring to the traditional guise of Fate," Fate said. "In reality there are many destinies and so there are many Fates. Though each Fate is like the one you mentioned, three souls inhabiting one body, sharing it equally. We personally weave the tapestries of your family."

"Not that I am saying I believe you," Buffy said as she tried to sense whether or not Fate was a demon. Her Slayer senses were not telling her anything about the man. "But if you weave the tapestries of life, why did you take our mother away?"

Fate's appearance shifted to that of an old man. "We do not arbitrarily determine when a life ends. But we do apologize for ending her life when it had. But think of this. Would you have preferred her to suffer or die as she did?"

"She died alone," Dawn said. "She should have had us with her."

"You are right of course," Fate said. "And we apologize again."

"So why are you here?" Buffy asked.

Fate shifted his form back to the first man, who they noticed was a young man, maybe not much older than they were. "Because of Dawn, and before either of you say anything. We are not here to warn you of her death. She will not for a very long time. We are to tell her she is a Millennial."

"A what?" Dawn and Buffy asked simultaneously.

"A Millennial, is someone usually born on January first of a millennium at exactly one second after midnight. Dawn was created on January first of the year two thousand exactly one second after midnight. She is a Millennial, she will live for the entire millennium. She is the Spirit of the Millennium."

"What does that mean," Buffy asked. "I get that she will live like a very long time, watching the rest of us grow and dye in front of her. But the rest …"

"She will feel Earth's woes and joys. The last Millennial was severely depressed in the Great Depression. And she felt deliriously happy during the Roaring twenties. She has the ability to transform into energy and travel through power lines and anything that uses such energy. She will also have the ability to use and control that same energy. I know comic books are not your thing, Buffy. But do you know the basics about Superman?"

"More or less," Buffy said.

"Dawn's body will be a giant battery, she can store the energy she takes in and release it later into a device or at any form of life in her defense her own or another's life."

"What if I don't want this responsibility?" Dawn asked.

"I am afraid it is too late to back out," Fate said. "The moment you were created it was too late to back out. You are the Spirit of the Millennium."

"I don't want to live that kind of life alone, can …"

"We have already anticipated that request," Fate said as it looked at Buffy. "Your life, Buffy, is tied to your sister's. You will live as long as she. The last day of the millennium when she dies, you shall as well."
