(Wait, I messed up.  The shaft is there, but also:) 

Directly in front of you, the sewer tunnel expands into a circular hub.  Two passages continue on to the north and south, and a stone ledge rises out of the muck.  With your perception check, Gil and Dylan see an irregularity in the wall.  

 (Sorry guys.  That's a major screw up haha)

(No worries!)

"Ah ha!  Anyone else spot this wrinkle in the wall down here?   Maybe a secret door of some description?"

Dylan will have a look around to see if he can spot any sort of opening mechanism, and also place his ear to the wall where he suspects the door to be and see if he can hear anything.  This really is not my forte.  I'm sure there should be a box-man we can get to do this instead of me.

I'm with you Dylan, let's check out out. '

You manage to pry the door open by pulling at the seam.  Despite its apparent weight, if moves easily and quietly. Happy to just get out of the muck, you all climb out of the stream and walk through the door into a short hallway.  It deadends into another hallway to the right and a room to the left.  You peek your head around, looking for enemies which... surprisingly are not there.  You look around and see many rusty weapons and threadbare clothing just strewn around.  

"Seems to be a storage room of some kind," Dra'vos says picking up one of the rusted weapons. "Does not look like anyone has been in here in quite some time."  Dra'vos then casts Mending on the rusted weapon in his hand to see if it has any effect.

"Eekz and mates shouldn't be 'ere, gobbo eaters everywhere!" Eekz shudders at the dark sewers, he heard the stories from the street urchins about places like this.

Dylan will move to the hallway, standing guard. 

Sylivar shrugs, content to press onwards. It was better than the sewers.

"Unfortunate, almost makes you wish they'd just continued with those yellow marks...On to the next one then?" Gaèl asks, pointing to the hallway to the right.

Gil pauses scanning the room, "I wonder if the rusty weapons and torn clothes are a red herring."

Dra'vos, casting mending repairs improves the quality of the dagger you hold, leaving it a clean, but ultimately plain dagger.  If you are interested, there are also rusty shortswords, daggers, and a broken shield in the area, but nothing of particular value beyond that.  

Gil, you look around and with that role, you notice that the floor is covered with gunk underneath, and that the weapons are haphazardly placed in groups.  Most indicative of the room's purpose is the impromptu shower and drain in one corner.  It seems to be something of a coat room or armory, where people coming in from the sewers can clean up a bit before heading into the rest of the hide out.  

Whenever you decide to continue, give me a stealth roll.

Sylivar pockets a dagger or two. There's no telling when a spare dagger could come into use, even if they were quite rusty.

"Into the room first, or would you like to head down the hallway?" he softly asks, glancing at the two options. 

Dra'vos stores the dagger he mended on his belt with his other, "If we are going forward we should be careful we do not know what is ahead."

Dra'vos stealth: 4

(is there a map, I'm a little confused).

"Slowly, slowly, catchy thiefy, or something."

Stealth:  12

(The room on the left was the messy room with the daggers and clothes)

Continuing down the hallway, you sneak past a goblin on the left.  You can't see exactly where his line of fire is, but there are two wall length slits in the wall that he could have easily fired through... if he hadn't been dozing.  He seems on the edge of waking up when you walk past, but he grunts and grumbles and continues to sleep.

You walk into another open room, which has six beat up straw-stuffed mattresses.  The only thing of note in here is the door on the far right corner of the room, and as you approach it, you can hear voices.

"Well, they don't know we're coming.  Might as well make the most of it."  Not waiting for one of his less stealthy companions to make a noise and alert the occupants, Dylan will kick the door open and move rapidly into the space beyond.  

(apologies if I'm moving fast, I see Dylan is quite the chaotic type when in these sorts of high pressure environments.   Feel free to ask me to slow down if wanted!)

Syl follows Dylan's lead into the room, intending to quickly subdue any hostile enemy before they can react.

Gil files in after the pair quickly moving to the side and scanning the room.

Dra'vos follows suit ready to cast if there are any apparent hostiles beyond the door.
