They weren't sure if the employees in the lobby were evil or not, so they kept walking keeping their formation. They reached a set of stairs, going down.
"Any ideas what we're up against, Sam?" Asked Prue
"No, but I guess whatever it is lurks down those stairs" Replied Sam
"Well aren't you a joy" Said Jack
"You'll learn to love me!" He said.
They made their way down the stairs.
"Well, this is the most bizarre place I have ever been" said Dean, they found the stairs led to a great expanse of dark nothingness, the floor felt like it was covered with ridges they were disused railway lines.
"What the hell is this place?" Asked Piper
"I have no idea, but Sam why don't you go and try to find where Phoebe is, Dean and I will go that way"
"Ok" Said Sam
"Wait Sam, are you armed?"
"Of course" He said pulling two knives out to show Dean
Piper and Jack made off in the opposite direction towards the growing darkness.

Piper and Jack had been alone for about an hour now, no idea if the others were alive or not, or where the inhabitants of the place were, they or it could be just around the corner for all they knew. After a while of silence they found the threat, and it was terrifying, uncharacteristically Jack and Piper didn't wait to fight, the fear it instilled in them made them automatically run in the opposite direction. Part of its power seemed to be the ability to cripple its prey with fear, they knew it was after them.
The thing was in the form of a young woman, she had hardly any hair, but the wispy, fine hair she did have was a dull grey color, she wore brown rags and the most unnerving thing about her was that both her eyes were closed but she still was able to see.
"What the hell was that. I've never been so scared in my life" Said Piper
"It feel like I am in one of those dreams when something is after me and I can't get away" Said Jack
"I know what you mean, that sense of dread and sheer terror"
It found them again, Jack started running and when he looked back Piper was far behind him.
"Piper!"
Piper was running, panicing, even though she ran as hard as she could and all the demon was doing was walking it was still catching up. She gave up and decided to try and fight. The thing however grabbed her from behind with a cold arm around her chest in a vice-like grip. The thing added to the terror by carrying everything out accompanied by that awful moan, it stood with her in its grip doing nothing as Piper screamed Jack's name at the top of her lungs only to discover to her utter horror that the same thing was happening to him, he screamed everybody's name, Dean's, Sam's Piper's, Phoebe's and Prue's. Calling his big brother's name first seemed only the natural thing to do, although he knew it was useless Dean was far away.

Dean and Prue felt the same dreadful feeling as Jack and Piper had done, only difference they had not encountered anything yet.
"Dean, are you scared?"
"Terrified, you?" He answered honestly, he wasn't compelled to lie to Prue
"Yeah"
A light blinded them in front of them stopping them in their tracks.
"It's my Mom" Said Dean, instinctively sensing it.
"Yes Dean it is. Listen to me both of you. Your fear is crippling you, be brave and that is the key"
"Mom, I love you, I really do, but please don't get all cryptic on me, I'm really not in the mood"
"You are definitely your father's son!" she said fondly.
"Mrs. Winchester, what is it that is scaring us so much" said Prue
"I don't quite know but I know it creates a crippling fear into its victims, stopping them in their tracks. Jack and Piper have just fallen victim to. Hurry, save them" She said and faded as quickly as she'd come.

Sam heard Jack call his name in a blood curdling desperate yell, something had happened, was Dean and Prue alright? He had no idea, and then he heard a voice emerging from the blackness around the corner.
"Don't come any closer, please" It began, then became hysterical "Please, Please..."
Sam turned the corner.
"Phoebe, it's ok, I'm here"
"Sam?" Relief overcame her when she saw him.
"What is it? What took you?"
"Sam, it's not it, it's them" She informed him "Behind you!"
The same sort of demon that Jack and Piper had fallen victim to was behind him. Sam drew his knives and buried them deep inside the thing's body, the demon turned out to be unharmed and Sam's knife disappeared.
"What the hell was that! What did it do with my knife?" Sam was completely flummoxed, after taking the knife it had also disappeared.

"Dean, your Mom said to be brave, so we have to be brave" Said Prue.
They entered a dark room, a dirt floor about six meters square.
"Where are we?" He asked
"We are the Searchers. We search, we find and we kill anything that opposes us and anything that works against the forces of evil" Said a voice, a child's voice, it struck Prue and Dean dumb, and they were lost for words.
"We sought to find you, the two powers of three. We now intend on bringing your death."
"You've got my brothers haven't you?" his sentence was ended with an arm around his chest forcing the air from his lungs. Prue was restrained in the same way, she astrally projected and touched Dean's hand. The connection was made, their powerful abilities combined their eyes flashed green and Dean turned and threw the Searcher that was restraining him and smashed it against the wall. Prue did the same thing with hers and proceeded to throw six searchers against the wall in front of her with her strengthened powers of telekinesis. Dean threw a killer punch in the direction of a searcher. The searcher that made off with Sam's knife now appeared in the middle of the fight and thrust the knife in Dean's left flank. Prue ended its life in a swift movement and turned her attention to Dean.
"Ow!" He paused to pull Sam's knife out of his side.
"Ow? Is that all you can say? You got stabbed!"
"I must be immune to it, at least until this power let's up"
They carried on fighting. Prue had an idea.
"Dean, give me Sam's knife"
He handed it to her and she cut her own hand with the knife. Two sets of blood were now on the knife.
"Noooo, go fellow Searchers, flee. They are 'the two', go, we underestimated them"
"Too late" said Prue.
Dean held the leader down to the floor as Prue smeared Dean's blood from the knife onto its forehead, it screamed
"No, the blood of the two. No" This yell could be heard by everyone in the underground lair.
At that instant everywhere the Searchers were they released their prey and fiery chasms swallowed them up and took them back deep into the pits of Hell. The Searchers were gone and Dean had finally weakened from the stab wound.

Leo awoke, he looked into the eyes of the elders who had healed him.
"What are you doing here, isn't it dangerous?"
"No Leo, the threat is gone, it is safe again. Go and save the Piper injured Winchesters, quick Leo."
"Wait. My boys are hurt?" Said John Winchester bursting through the door.

Leo had gone and left John waiting alone.
