"Are you absolutely certain you've never had a supernatural encounter before?" Jefferson asked.
"If I did, you would probably already know about it," Sam replied. Gesturing to the strange contraption on her head, she asked, "What exactly does this thing do?"
"Probably best you don't know," Constance said. "Have you ever been part of psychokinetic biological inhabitation?"
"I don't even know what that is."
"It's scientist for being possessed," Hogarth explained. "Don't worry, I had a hard time understanding what that meant, too."
"Okay, so what does any of this have to do with me?"
"You were being targeted by two Prime Morganians," Jefferson said as if it explained everything.
"I have no idea what a Prime Morganian is."
"Prime Morganians are the top followers of Morgana Le Fay," Constance explained. "There are five of them, and you met two a little earlier. If they were after you, they wanted something."
"What could I have that they want?"
"Your soul," Jefferson said. "You must be the last living descendant of Morgana."
"You're saying that my ancestor was an evil sorcerer from Camelot?"
"These guys surprise me all the time, too," Gordon chimed in.
"It'd be wise to assume that that's why they were after you," Constance said. "They need a soul from Morgana's bloodline to allow her power to reach a level for it to wreak destruction across the world and raise an army of the undead."
"That being said," Jefferson said, "it's time we gave our gear an upgrade. I took the liberty of developing a new blaster to attach to our proton packs."
He took out a gun that looked like a space blaster and placed it on the table.
"Whoa! What is that?" Hogarth said with interest in his voice.
"It's a prototype boson dart rifle," Jefferson explained. "It fires super de-polarized bursts of extremely volatile boson particles. I rewired the cyclotron chamber to store the particles instead of releasing them from normal pack ventilation or energy dissipation, based on designs for a prototype proton pack developed by Dr. Stantz and Dr. Spengler in the early Nineties. Once hooked up, the rifles will be able to fire the boson darts like a shotgun, allowing us to deal serious damage to ghosts."
"Sounds destructive."
"Getting back on topic," Constance said, "we need to keep Sam out of Morgana's reach until we can stop her once and for all."
"Okay," Hogarth said. "How exactly do we do that?"
"We'll have to capture the remaining two Prime Morganians before going to the museum and have them get rid of the Camelot exhibit. It's too dangerous for it to be there."
"Why?"
As if answering Hogarth's question, Jefferson slammed down an atlas on the table next to the boson dart rifle. The page that was open was a map of San Francisco. Two red lines were drawn across the map, forming an "X" somewhere in the center.
"Am I supposed to know what this is?" Hogarth asked.
"Ley lines," Jefferson answered. "They're currents of supernatural energy that run all over the world. Paranormal activity always happens along them, but when they intersect, the activity is much stronger and more dangerous. A ley line intersection is the perfect location for Morgana to gain the strength she needs to unleash chaos."
"We've been doing research about Morgana and the museum ever since our assignment there," Constance added. "That's when we discovered the San Francisco ley lines. Every major city in the world has at least one ley line intersection within the city limits, but San Francisco has an intersection of five ley lines. That's why it's the most haunted city on Earth."
"Let me guess," Hogarth said. "The ley lines in San Francisco intersect where the museum is located."
"Exactly. They had the Camelot exhibit built there so Morgana could draw strength from the ley lines before she was freed."
"Hang on a minute," Gordon said. "Despite my beliefs in the spirits of the Mother Isles, I've heard about the legend of Morgana Le Fay. The only thing that could free Morgana from the sarcophagus she's trapped inside is the sword Excalibur, not enough ghost energy."
"But a sword that is supposed to be Excalibur is on display in the Camelot exhibit at the museum," Jefferson pointed out. "If it truly is Excalibur, then they'll use that to free Morgana."
"What about the Prime Morganians?" Hogarth asked. "Don't we need to handle them, too?"
"Yes, but something's not right," Constance said. "The Prime Morganians are very powerful and could have dispatched us with a wave of their hand. But they made it too easy."
"They must have wanted to be caught," Jefferson said. "But why would they do that if they knew it meant getting trapped inside an inescapable containment unit?"
"Maybe because they knew it would let your guard down," said a voice.
Suddenly, a blinding light surged through the building. The table that had the boson dart rifle on it reared up and grabbed Jefferson with its legs; the hose of a proton pack suddenly wrapped around Constance's body and pinned her to the floor; bricks extended from the wall like fingers and snatched up Gordon; the refrigerator came to life and heaved itself on Hogarth, squashing him beneath it.
At that moment, a man with a large black beard and dressed in a charcoal black coat and pirate hat hovered up through the floor, a sword with a golden hilt and a black blade slung over his shoulder. Behind him stood a man with curly jet-black hair and a mustache. He wore a black and white suit with a tie.
"Blackbeard," Constance said, her voice laced with venom.
"Good to know that I am still remembered after so many centuries," he replied.
"Run, Sam!" Hogarth cried.
Seeing Sam turn and try to run away, Blackbeard raised his sword high above his head. Sam was suddenly pulled back to him as if something was dragging by her shirt collar. She kicked and screamed, but to no avail as Blackbeard caught her in his free arm and held her tight. John Wilkes Booth pulled out a pistol and pointed it straight at her face.
"Leave her alone!" Hogarth yelled.
Booth pointed another pistol at Hogarth and gave him a fiercely angry look that told him to shut up.
"I'm afraid that's not an option, Mr. Strange," Blackbeard said. "Our Mistress needs this young lady in order to fulfill the goal she placed upon herself many centuries ago. When her spell is complete, the world will become hers as it was meant to be.
"You all should have heeded Abigail's warning. Now, you shall pay the price and watch your city crumble. If any of you ever try to stop us again, you will die very painful deaths."
"You won't get away with this!" Gordon roared.
Blackbeard glanced straight at him with a triumphant smile.
"I'm afraid we already have."
With that, he, Booth, and Sam disappeared in another blast of light. No sooner were they gone, the Ghostbusters were freed from their restraints. At that moment, an alarm went off.
"What was that?" Hogarth asked.
"The containment unit!" Constance cried. "They shut it off!"
"Can't we get it back on?" Gordon asked.
"There's no time!" Jefferson shouted. "We need to get out of here now!"
The Ghostbusters quickly scrambled down the stairs, grabbing a surprised Amy as they ran by, who asked them what was going on. They turned around in time to see a massive beacon of light explode from their headquarters. Ghosts of all shapes and sizes burst from the beacon and began to scatter about San Francisco.
Hearing the sound of sirens, the Ghostbusters turned around and saw police cruisers pulling up to them.
"We're so glad you're here, officers," Constance said as they climbed out. "We need to start evacuating the city before-"
"Hands up! All of you!" one of the officers ordered as he and the others pulled out their guns. "You're all under arrest!"
"This wasn't us!" Jefferson protested. "Morgana Le Fay's goons shut down our containment unit!"
"Not even the judge is going to believe that," the officer snapped.
"It did sound pretty ridiculous," Hogarth told Jefferson.
