"Suggestions would be helpful right now," said Piper as the demon moved on them.
Prue used her power on the carpet underneath the demons feet. The carpet suddenly yanked out from underneath it, sending the demon clamoring to the floor. It rose and faced the sisters again.
"Prue," screamed Phoebe, "the broken glass from the window."
Prue turned her power on the shards of glass littering the floor. Dozens of pieces rose off the floor and flew to the demon. They embedded themselves deep in the creatures flesh.
The demon howled in pain and fell to the floor. Within seconds it lay still, killed by the dozens of small glass shards covering its body. The three watched as the body of the demon evaporated away into nothing.
"That was different," said Prue.
"Leo," called Piper, "Leo, get down here. We need some information."
"I'll check the Book of Shadows," said Phoebe, as Leo orbed in.
"What's up?" asked Leo, noticing the shattered window. "Redecorating?"
"Demon attack," said Piper. "A demon that looked like a big furry dog."
"What?" questioned Leo.
"Piper's right," said Prue. "This thing crashed through the window. It was covered with red fur and had only three fingers on each hand. Or paw. Or whatever."
"And it was immune to our powers," said Piper.
"Immune?" questioned Leo. "What do you mean immune?"
"Just what I said," said Piper. "They worked once but the second time we tried, nothing. It just ignored our powers."
"That's impossible," said Leo. "There was only one demon I know of with that ability and it couldn't possibly have been here."
"Well, it was here," said Prue. "Impossible or not, it was right here in the living room. How do you think the window got smashed?"
"Listen," said Leo, "You guys know I believe you. But there has to be another explanation for what happened."
"Why?" asked Piper.
"Because that demon was vanquished almost two hundred years ago," said Leo. "It was called a Banka. There was only one and a witch vanquished it in the early 1800s."
"Then there must be a second one," said Piper. "It was right here in the manor and we only survived because Prue was able to use the broken glass from the window to kill it."
"If it is a Banka," said Leo, "then we have a problem."
"Leo's right," said Phoebe, coming down the stairs. "This Banka was created by a warlock in the early 1800s. It seems to have only one instinct. To kill witches."
"We killed it," said Prue. "So what's the problem?"
"You didn't kill it," said Leo. "You just dissipated its energy temporarily. It will reform in a few hours and when it does, it will be back."
"Okay, we just dissipate it again," said Piper.
"That's the problem," said Phoebe. "According to the Book of Shadows, it gets harder to kill each time. Every time it reforms, it's stronger. And it's also immune to any attacks it survives."
"Oh, lovely," said Prue.
"Leo," said Piper, "you said a witch vanquished this thing once before. Well, we just use the same thing to vanquish this one."
"Except that no one knows how he did it," said Leo. "He didn't tell anyone beforehand and he died vanquishing it. Not even his own White Lighter knew how he planned to do it."
"The Book of Shadows only mentions something about a special talisman," said Phoebe. "But there's no clue what that talisman is. Or was."
"So we have a demon after us," said Piper, "whose only purpose it has is to kill us. And no one knows how to get rid of it?"
"That's about the size of it," said Leo.
