Ringworld is property of Larry Niven. All characters from the Buffyverse are Property of Joss Whedon. Everything else belongs to me.
Buffy turned off the gravity generator. The hum of staggering energies began to fade from the particle accelerators that covered thousands of square miles of the ringworld surface. Beneath her was the forces needed to create and vibrate a quantum singularity and twist it into wormhole. The hard part was getting it to rejoin space-time at the right point in the past. All she had was her memories to guide her and hundreds of years of personal experience.
Her keep was under the Map of Mars. It had been long abandoned by the intruders Louis Wu and the Kzin Chmeee. She had no idea where the Hindmost was currently. After the Fringe war, after the battles for the ringworld throne she waited for the Humans of Known Space to abandon their search for the ringworld and then she conquered the ringworld and build a device to communicate with the past for reasons that were so compelling that after hundreds of years she still could not think of an alternative plan.
Buffy watched them on the high definition monitor. She spied on the activities of millions of Dawns descendants from cameras mounted from the spill walls and elsewhere. The stupid monks never came back and uncreated Dawn. So here she was, five hundred years later, the oldest human in the universe, driven by a mystical compulsion to protect her blood. Buffy never once felt sorry for herself.
She was not like the Pak Protectors. They were only driven by a biological need to protect their own. They were xenophobic and dangerous. Buffy killed them all with a bottle of perfume. Of course, the perfume was crafted to mimic the pheromones of each particular protector's clan. In a fair fight, Pak Protectors are no match for Slayers. She regretted killing any natural being. But she had to do it. They could have gotten in her way.
She was the first person they had seen with gray hair. She said her name was "grandma" as more of a joke than anything else. The name stuck. The descendants that knew her called her that. She had waited fifteen years after she arrived on Ringworld before taking the tree of life. Six months after emerging from her coma Buffy came across her first vampire of supernatural origin on the ringworld. She killed it. She was still a Slayer and now also a Protector against threats both secular and divine.
Buffy brought up the smaller picture-in-picture video. It expanded to fill the huge three hundred inch monitor in front of her. The display showed the light from the braking drives of hundreds of general products ships. The Puppeteer assault fleet had finally arrived.
"Time to go to work." The Buffy Protector said.
Xander entered the summer's home. He gingerly stepped over the broken furniture. His eyes landed on Buffy and Dawn. It looked like they were having a heated discussion, a heated discussion with battle axes.
"Buffy I hate to axe this but have you eaten your crazy flakes today?" Xander said as he made his way into the living room. The main chair was turned over and there were signs of a struggle. The fireplace poker had blood on it.
"Was glory here?" Xander asked. His voice was full of concern.
Buffy looked at him. She looked preoccupied as if she was making plans.
"Glory has to be handled but she's not the main threat.' Buffy said. She sat the axe on the sofa and got her purse. Buffy pulled out her one and only credit card. She still had a few hundred dollars of available credit on it.
"Xander, I need you to pick up some items from the hardware store. I'll make a list." Buffy wrote down a list of items and handed it to Xander.
Xander read over the list.
"An AC relay, receiver actuator, pressure regulator, air mass relief valve, 3 way valve, quick release fitting for an air line, solenoid, vacuum pump. What are you building? A pneumatic gun?" he said.
"Also I need twenty ping pong balls and a hypodermic needle. " Buffy said.
"Seriously?" Xander didn't know if he could get everything.
"Seriously." Buffy said matter of factly. "Go!"
Xander went without looking back.
"You think you're going to stop Glory?" Dawn asked. She folded her arms and stared at Buffy in defiance.
"I'll deal with Glory in due time but she's not the real threat." Buffy said. "The real threat is Willow. She could kill us all with her magics."
Buffy removed a stake from the battle chest and grabbed her battle axe from the sofa.
"Don't think I've forgotten about Spike in the basement." She said as she brushed past Dawn.
Dawn stood there helpless . She didn't know what to do.
