Ringworld is property of Larry Niven. All characters from the Buffyverse are Property of Joss Whedon. Everything else belongs to me.
She decided to tell them about Dawn.
Buffy had already informed Giles of what she found out about Dawn from the monk who died in her arms. Now with this new information about the ringworld she had to tell everyone about the true nature of Dawn and about the real reason Glory was here. She wondered how they would take the news that Dawn was the mother of billions. It became even more important that Dawn be protected now. More than one world depended on her living a long and fertile life.
In the back of Buffy's mind those billions of lives called out to her. She felt as if she was under a compulsion to leave Sunnydale and fly out to them which was ridiculous. How could she care about people she had never met. It was then that she thought about the endless commercials on television showing starving dark skinned people in Africa. She had never cared about them past the sense that their suffering was an inconvenient intrusion into her happy world view.
"Why do I care about people I've never met?" She thought to herself. She had the answer before she knew it. "It's because I feel connected to them."
"Buffy?" It was Xander. "You called this meeting."
Buffy looked around. Everyone was there and they were staring at her.
"A few days ago I went back and investigated the warehouse where I found the sphere." She said.
"Yes, I remember." said Giles.
"That's when I met Glory for the first time. Let's just say I barely got out alive." Buffy paused for everyone to perform their typical show of concern then she went on. I met someone there, a monk who claimed that Dawn was an artifact. That she was actually a green ball of energy that was molded into the form of a young girl. They gave her to me to protect."
"Yeah, Buffy but I remember that time Dawn and I…" Xander was about to say.
"False memories." Buffy said abruptly. "The monks altered local reality
"What about all the times I baby sitted?" Willow asked.
"You have never baby sitted for Dawn in your life. Dawn has been in this world for less than a month." Buffy's tone was sharp. "The monks changed all of our memories. It's obvious really."
Willow had never known Buffy to be condescending. Just how smart had Buffy become?
"Now there's this other thing." Buffy looked over at Willow for support. She was about to tell everyone about the ringworld and Dawn's billions of descendants.
"The other night Willow performed a locator spell to find Dawn. I spell indicated that somehow she was in deep space in the general direction of the galactic core." Buffy waved everyone to silence. "Hubble images from that region of space showed a G2 star surrounded by a solid ring of matter. The sunward side of the ring is terraformed. That ring could easily hold fifteen trillion people." Buffy could feel the sheer weight of that number. She now had the intelligence to understand and that made her anxious.
"Why now? Giles asked. "Willow's performed locator spells before but they have never indicated anything skyward?"
"We think it's the wormhole." Buffy answered.
"So now there's a wormhole?" Xander muttered.
Buffy smiled over at him.
"The monks didn't think it through." She said. "They didn't appreciate or care about the future effects of shoe horning Dawn into this reality. And now thanks to a cute little warp in space-time the future is now."
"Other than being cool, what possible effect of knowing about the ringworld would have on anyone here?" Xander was curious.
"I can feel them in my heart." Buffy said with sadness. "The monks gave me a fierce compulsion to protect Dawn and that was ok as long as there was just Dawn." Buffy paused a moment to choose her next words. "Now that I know about the others, about her descendants, the compulsion is stronger, much, much, much stronger."
Buffy looked at them with tears in her eyes. "I don't think I can stay on Earth much longer. I'm going to take Dawn and move to the ringworld."
The Scooby gang was in stunned silence.
