Ruslan, Baril, and Lou:
You can see the bottom vaguely, though even with the ability to see in the darkness its sketchy. The sounds of thick liquid are accented by a slightly moving ground a good distance down. Igor doesn't acknowledge Ruslan's words in any way other than starting the climb down an old, wooden ladder that's on one wall of the tunnel going down.
It reaches the bottom in more of a squish than a splash, and the white skull can be seen looking back and forth for a moment before looking back up to Baril. Down a moment later, Baril finds himself in knee-deep sludge. Its probably good that you can only see the liquid in a black and white, as it feels as unpleasant as it probably looks in colour.
The ceiling is about seven feet high, and there's a good ten feet on your left and right before rounded, stone walls take over. The tunnel goes both ahead of you and behind you. Ahead, you can see a T-shaped junction about sixty feet ahead(at least, its at the edge of your vision). Behind, there is a T-junction at about half that distance...though there are no lights anywhere. And other than the sound of the liquid that's at your knees moving, you hear nothing else beyond your own breathing echoing around quietly.
Toryn, Pabsit, and Oskar:
The Dwarf, Toryn, nods strongly at Pabsit's words. He doesn't actually say anything, but steps over to the door, stretches a little before cracking his fingers, then takes hold of the metal bars that are on the door. Without even calling on assistance from his protector, Toryn pulls hard.
There is a sudden, loud crack and the lock on the door snaps off. The door swings outward and open, revealing a small entrance hallway. At the end of it you can all see a nicely decorated room with a large table and chairs. From where you stand, you see no signs of recent habitation.
