This hallway is empty. You don't find or hear anything of interest. 

Bryce will head towards the East door, while the others check the alcoves. Getting close he place an ear by it to see if he hears anything. 

Perception: 9

Bryce cannot hear any sound from the other side of the door.

"Very well. Get ready" Alysa whispers seconds before open slowly the door.

Alyssa and the group of adventurers slowly and quietly sneak into the next room.

The walls and floor of this room are covered with streaks and splashes of dried blood. Two dangling bodies are shackled to the east and south walls. One is an elderly male human; the other, a young female tiefling. Both are covered in bloody gashes, and neither is moving. In the middle of the room is a sturdy wooden chair with a bloody whip draped over it. A bucket half filled with salt sits on the floor nearby.

Alysa approaches the two bodies and checks if they are still alive.

Medecine (if needed): 17

One body, the man on the left, is dead. The other body, the woman on the right, has a very faint pulse and seems stable but barely alive. 

Jhasso approches the woman and gently places and hand on her head, while casting a healing spell.

"This man does not like torture in any shape or form."

Action: Cure Wounds: 8 HP

Alysa helps Jhasso and removes the prisoner from her chains and places her on the floor.

Nyx flies to the salts and inspects them. What manner of minerals are these?

Bryce heads in seeing the others are taking care of the woman, takes down the other body. After that he searches the room and heads to the  door making sure to keep an eye out in case someone comes back.

Perception:23 

[Nat 20!]

Wincing at the callous treatment of life, Hal was releived to see his new group of fellow explorers treat the dead with respect and help out the Tiefling.  As Bryce moved to the next door, Hal turned to look and listen behind them to make sure they were not being followed.

OOC: Perception check [11]

When Alysa and Jhasso remove the shackles of the young tiefling (the keys they found on Yignath fit the shackles) and heal her, she slowly comes to. 

With closed eyes she mumbles: "Please, not again. There is nothing else I can say." She turns her head away. But somehow she feels that the atmosphere in the room has now changed and opens her eyes. She looks very confused, sceptical and very weak. "Who,... who are you?"

Nyx has seen similar crystals being used by people to make their food more interesting. This bucket here is full of blood stains and the salt is red. They realise that the salt here is probably used in a way to cause pain, how exactly is beyond Nyx's knowledge. 

When Bryce searches the room, he cannot find anything beyond the torture tools, the shackles, the salt and the body. However, he finds a small area of wet cobble stones near the north door. Almost as if someone with wet boots stood there for a little while, then left again through the north door. 

Hal is unsure, but he thinks, he may have heard a faint noise coming from the hallway. 

Alysa approaches the poor tiefling and tries to display a friendly face. With her tough job, she almost forgot how to smile.
"We are the protector of the city. You are safe now. We can protect you and we will bring you back to the surface. What is your name ? What can you tell us about this place, who are your tormentors ?""

With a soft voice the tiefling speaks: "My name is Vendetta Kress, I was attacked in the Lower City, one blow to the head knocked me out. Then they brought me here... to be tortured. I distribute wine and spirits for the Oathoon patriar family. They wanted to know everything about the business." She takes a moment to compose herself. When she looks at the other corpse still hanging on the wall, she flinches. Then she looks Alysa in the eye: "We should leave. They'll probably return soon! I always heard what sounded like a heavy door just outside this door!" She points to the northern door. "And I heard water splashing when they walk through it! We need to be careful!"

Dividing his attention between the Tiefling and the hall behind him, Hal started to walk back down the hallway that they came from to investigate a possible sound, but realized that another fight with either cultist or inanimate objects might not be the wisest course of action while trying to protect a wounded delivery girl.

“I’m not sure, but we may have company soon guys.  Let’s take Vendetta’s advice and move along.”

"This man would advice moving along."

Nxy agrees. Should we open the North door, Alysa?

Nyx takes position above and to the side of the north door, to support Alysa.

“Where going? I’ll cover the rear, just in case they do come up on us!”  Bryce will follow the others, stopping justby the door. He has his mace and shield ready just in case something happens.

Alysa walks first through the door and makes some noise while opening it. There is a flickering light coming from the tunnel.

When Alysa turns the corner to find out where the light's coming from, she spots a cultist, who, when he realises that she is not one of them, runs off down the hallway a split second before Alysa can react. To Alysa, it feels as if he was standing guard before running away. 

You can hear him banging on a door, shouting "Intruders" at the top of his lungs.
