Ringworld is property of Larry Niven. All characters from the Buffyverse are Property of Joss Whedon. Everything else belongs to me.
The Buffy-Copy wandered around the huge laboratory. She and Dawn had been pulled out of time by the Buffy-Protector who presumed to be her future self. The Buffy-Protector in the future had used a tiny portion of Dawns keyness to open a window into the totality of space-time and the Ringworld as a Quantum computer to sort through the infinite dimensionality of reality.
Like an artificial locator spell, the Ringworld found an exact point in the past that contained the dimensional vibrations of the green energy that lay within Dawn.
The Buffy-Protector had made a perfect quantum copy of both Buffy and Dawn as well as a copy of the magics they both contained.
The Buffy-Copy sat in a chair before a huge control panel. Her augmented intelligence could see a pattern in the lights. She pressed one of the buttons and the image of thousands of Dawns descendants filled one of the view screens. She felt the protector spell kick into a high scream.
"Alright." She said to Dawn. "Let's get settled in."
She held Buffy's hands in hers as she recited the spell.
"I found a way to remove the smartness spell. I can return you to your former self." Willow said to Buffy.
"Great, now I go back to being dumb." Buffy said sarcastically.
"Buffy, you were never dumb. Remember when Professor Walsh asked you to be a teaching assistant based on the quality of your work?"
"Yeah."
"Well, that proves that you've had a brain all along."
"Great. Now I feel I should be going over a rainbow or something."
"In any case, that spell was way too advanced for you. It called upon a source of secular intelligence known for it's pride which is not for the good." Willow said.
It had been a few days since they had closed the Hellmouth. They had all settled into a large resort hotel just outside of Sunnydale. They kept a low profile and avoided agents from Homeland security. The media was shaping the story as some sort of a terrorist attack on California. The media was right, but just not in the way they thought. The First was definitely a terrorist.
Willow began the last part of the spell. She handed Buffy her dog eared copy of "Elementary Calculus."
"Just start reading something." Willow said.
Buffy opened the book to t random page and started reading.
"Consider a real function (f) and a real number (a) in the domain of (f) When (x) has the value (a) then a,f(x) has a value f(a)." Buffy droned as she read.
Willow placed several crystals together and chanted.
Buffy looked at the page she was reading. The characters all seemed to blur together and the words on the page made to sense. Buffy closed the book in frustration.
"Can we go to the mall or something? Buffy asked.
"I'm finished." Willow said. "Looks like we've got the old Buffy back."
Great." She said. "Now, can we go get some Flowers for Algernon?"
"They're insane!" The Buffy-Protector thought.
It had been hours since a single ship had appeared above the Map-of-Mars firing a singularity weapon at her laboratory killing Dawn. The Buffy-Protector had managed to reassemble Dawn from the exploded remains of the singularity using the Ringworld as a quantum computer to perform the calculations in real-time. Oddly enough, the Ringworld never got to finish its calculations. When it had gotten sufficiently close to finishing its calculations the magic that created Dawn from the green energy asserted itself and made Dawn again.
"Dumb magic." The Buffy-Protector thought. If she hadn't erased the information in the data buffers the Ringworld would still be spitting out perfect copies of Dawn.
"How many times have I tried to explain to the Puppeteers that I'm not dangerous to them? I'm not a monster." She thought. The Buffy-Protector caught a glimpse of herself in one of the polished parts of her machines. She saw an shape with leather hard skin that could turn a knife, oversized elbows and knees for leverage.
"I'm not a monster." She thought to herself.
