Part 3
The Doctor and Jo entered the caverns and the Doctor took out a flashlight to light the way. They soon found themselves walking in a edge of a cliff in the cavern and the fall looked very deep. "Watch your step, Jo." the Doctor told her. Suddenly, another shaking occurred and the Doctor fell off the cliff.
"DOCTOR!" Jo shouted.
Jo started to feel scared without the Doctor by her side until she heard a familiar voice. "Jo?" the voice called out.
Jo looked around to see where the voice came from. "Doctor? Where are you?" she asked.
"I'm down here." the Doctor said.
Jo turned around and saw the Doctor hanging at the side of the cliff. "Oh, it's good to see you alive, Doctor." she said.
"As do I. Now could you help me get up?" the Doctor told her. Jo bend down gently and pick up the Doctor from the cliff side. "Thank you for saving me, Jo." he said. The Doctor suddenly could see little light right near them. "Did you bring a flashlight, Jo?" he asked.
"No, I didn't bring any flashlight with me. I thought you had a flashlight."
"No, I dropped mine when I almost fall down."
Suddenly, the Doctor and Jo saw a woman in a red hood with white paint and black linings all around her face. "The high priestess will see you now, Time Lord." she told him.
"Should we follow her?" Jo asked.
"We have to. Meeting the high priestess will get this finish." the Doctor said.
"Are you coming or what, Time Lord? The high priestess is getting impatient." the woman said.
"Alright, alright. We're coming. You don't need to hassle us." the Doctor said and he and Jo followed the mysterious person.
Back in Liverpool, the Brigadier and Sgt. Benton are still investigating and they still couldn't find anything unusual in the city. "Anything yet, sergeant?" the Brigadier asked.
"Nothing yet. This scouting mission is getting more tiring and we're mostly wasting time." Benton said with a binoculars on.
"Have you found any geologist yet?" the Brigadier asked a UNIT soldier through the communicator.
"Sorry sir. But the nearest geologist is 50 miles away from Liverpool. It might take time." the UNIT soldier said.
"Don't worry. I'm sure the Doctor will find a way." the Brigadier said. Soon, the Brigadier and Sgt. Benton saw Captain Yates running to them with a piece of paper in his hand. "Captain Yates, what have you got for us this time?" the Brigadier asked.
"An urgent message from the Doctor." Yates replied and gave the paper to the Brigadier. The Brigadier looked at the paper and found really shocking details that was written on the paper.
"What is it?" Benton asked.
"If what the Doctor said is right, we're surely in major trouble. Captain, notify the mayor to evacuate everyone in Liverpool out of here."
"Will do." Yates replied.
"I think that we're already in trouble." Benton said.
"What makes you say that?" the Brigadier asked.
Benton pointed on an oncoming monster in front of them. The monster is covered in magma but also had rock as an armor. When the monster saw UNIT forces and charged at them, but they quickly dodged him. Sgt. Benton tried to shoot down the monster, but the bullets seem unaffected for the monster.
"Geez, when can we have monster that is affected by our bullets?" Benton asked.
"I always ask the same question." the Brigadier remarked.
"So what is that fiend?"
"It seems to be the threat the Doctor warned me about. And probably the cause of the spontaneous human combustion."
"So how do stop it?"
"I'm still not quite sure. Even a water pistol couldn't stop him." The Brigadier stopped talking when he dodged a molten lava that was thrown by from the monster's hands. "The only thing we could think right now is to stall the monster some time and prevent any casualties."
"Let's just hope the Doctor has found a way to stop it." Benton said.
The hooded woman led the Doctor and Jo to a room with many other hooded women chanting around the bonfire. On a platform near the bonfire, a live figure with a head that looks like she's been burned sat on a throne like chair, but partially weak to move or do anything. Next to a figure is a hooded woman that serves the figure as the speaker for it. The figure saw the Doctor arriving the room and it partially smiled at him.
"Who are these people, Doctor?" Jo asked.
"A very old religious group, Jo." the Doctor replied, "They go back as the time the Roman Empire was just flourishing."
"You mean like the cult you mentioned earlier?"
"Yes they are."
The burned figure leaned towards it's speaker's head and whispered something to her. "Ah, the Time Lord known as the Doctor." the speaker said, "The high priestess and my sisters welcomes you to our domain."
"I already know that you caused all this spontaneous human combustion, Sibylline Sisterhood. A cult of Soothsayers from ancient Rome and the cause of Pompeii."
"It was not caused by us, Doctor. You caused it and you will later on in your life during your darkest time."
"Why are still active?"
"We're a second wave of the Sibylline Sisterhood. We believe that we are the ancestors of the original sisterhood and find the island of Britain to be a suitable home for us."
"Why are working with the Pyrovilles?"
"They've been working with the sisterhood since the beginning. We find some criminal refugees who were escaping from Pyrovillia."
"And what about the spontaneous human combustion that's been happening?" Jo asked.
"They were mostly to see if they could fit for a human and Pyrovile hybrid. We first tested the waters of Liverpool and it was a moderate success due to the fear of the people that made the experiment almost fail. The Pyroviles then created the pills as a 'treatment' for the combustions and it was a success."
"You can't experimentally crossbreed another species. It will cause some catastrophic events."
"We will, Doctor. And there's nothing you can do to stop us." The Sibylline Sisterhood started chanted and held out the painted eyeballs to the bonfire and a violent shaking is happening.
"What is happening, Doctor?" Jo asked.
"Preparing for something worse."
Miles away, the Brigadier and Benton are still stalling the Pyrovile while Mike Yates and the mayor of Liverpool led the evacuation. "We can't keep doing this all day!" Benton said as he tried to shoot the Pyrovile.
"Don't worry. I think he's about to be tired by now." the Brigadier said. Just then, they saw some of the people who are evacuating Liverpool felt something weird and the next thing the Brigadier and Benton knew, they started to turn into Pyroviles.
