The Buffy-Protector readied for war.
Things had not turned out the way she hoped. Over a hundred years ago she had arrived on the Ringworld, killed the reining protectors and secured a place for billions of Dawns descendants. The Machine and Night people were not a problem. The vampires were something else. Turns out there were humanoids that had evolved to drink blood but they were not supernatural in origin. They were just people. As long as they stayed away from the children of Dawn she would stay away from them.
She had been on the ringworld twenty years before she met her first real vampire. It was right after she had taken tree of life. Her intelligence, already high, became laser like in its focus. A routine surveillance scan of the ringworld had revealed vampire activity. She watched helplessly as a small pre-industrial village was decimated. Forty seven people were killed right before her eyes. She recognized the attackers' body language from her days in Sunnydale. The Buffy-Protector watched the bodies for three days hoping she was wrong. On the third day, the bodies began to move. The new born dead began the hunt for more victims. She franticly scanned the ringworld and found many other instances of vampire attacks. She did the math in her head. The numbers came out to well over one hundred million vampires on the ringworld and growing exponentially.
The thought of hunting them down one by one was insane. Their numbers were exploding. She needed to kill them all, everywhere and at once. She had the answer before she finished conceptualizing the question.
Three weeks later the Buffy-Protector moved the shadow squares and exposed the ringworld surface to constant sunlight. Shadow squares were the inner rings that provided night for ringworld. She waited until the dead stopped burning and then waited some more. The Buffy-Protector returned the shadow-squares to their rightful place and returned to her surveillance. She reviewed the distribution pattern of the vampire attacks and came to a conclusion that stopped her cold in her tracks. The vampire attacks all originated from the same place.
Thousands of years ago a moon size asteroid had collided with the ringworld. Where the asteroid hit, the ringworld floor had been pushed clean out of the atmosphere. From the ground level it looked like a giant fist was pushing itself up through the ringworld floor creating a mountain. They named the mountain "Fist-Of-God." The Buffy-Protector analysis showed that the vampires originated from there.
Apparently, the "Fist-of-God" Mountain was now a Hellmouth. She didn't know why.
That wasn't the worst part. The Puppeteers knew about her and were terrified. They were sending an assault fleet to kill her and take control of the ringworld.
The Buffy-Protector readied for war.
If a single demon got back to the Fleet of Worlds it would be all over for trillions of sentient beings. They had no defense against the things she fought against. The Buffy-Protector was the only thing between life in the galaxy and total darkness. She gathered her equipment and headed to the control room under the Map of Mars.
"Help me Willow." Buffy looked at Willow. Her eyes were moist. "I'm out of control. I may have killed someone." After using her pneumatic gun against Glory she was surprised to find Ben lying in a pool of his own blood on her front porch. She didn't call the police. She used the house phone to call Willow and Giles.
Willow showed up fifteen minutes later with some healing herbs and first aid. Giles was still dazzled by the blasted door.
"Isn't he the intern from the hospital?" Willow asked. She knew she'd seen his face before.
"I don't know how he got here." Buffy said. "One minute I was fighting Glory and when I went to check he was laying there."
Giles stared at the prone bloody body of Ben. "So are you saying, there is some connection between Ben and Glory?"
"I don't think so." Buffy said. "Wil, I've been so out of my mind. I must have imagined it was Glory." Buffy looked desperate. We've got to do something about that protection spell. We've got to turn it down at notch."
"The protection spell is not the problem. It's there for a purpose." Willow said as she worked her healing magic over Ben.
"We've got to get him to a hospital. Mojo is no match for a CAT-Scan." Giles said. Willow agreed. Buffy and Giles took Ben to Giles car.
"I'll take him in." Giles said. "I want you and Willow to talk this out." Giles placed his hand on Buffy's shoulder to comfort her. "We'll work this out." He said. Giles jumped in his car and drove away.
Buffy re-entered her house. Her front door looked like a blasted heath. She and Willow sat on the sofa.
"I've made such a mess of things. I spent three hours chasing Dawn around; I almost killed Spike and Ben today. What can we do?"
"I think the real problem is the wormhole. It's exacerbated a manageable condition." Willow said. She tensed as she spoke the next statement. "I can't take the protection away. It's linked to Dawn. As long as Dawn exists the protection spell exists. The key is to get the protection spell to ignore the ringworld."
"The wormhole. " Buffy said. "We've got to get the protection spell to ignore the wormhole.
"Tabula Rasa!" they both yelled at the same time.
"Reengineer the tabula rasa spell to make the protection spell forget all about the ringworld and Dawns descendants." Buffy said.
"You want me to do a spell on a spell?" Willow asked.
"I'll help you reconfigure it." Buffy said as she thought for a moment. "You know, we still have a bigger problem."
"What?"
"The ringworld is unstable. If we don't save them, fifteen trillion people will die."
