The party continues down the long, counter clockwise staircase down. It goes dozens of feet into the dark depths until the light above is just a faint aura far above your heads, and since it lacks a railing the party is forced to hug the stone wall.
The air also grows warmer and the walls go from a cobblestone roughness to something slippery that you cannot make out without a light source. In fact the humidity is giving off a warm signature into the air that seems to also be limiting the effectiveness of infravision. A low chant also starts to be heard close to the heroes, as if a voice was mumbling to them in an alien language. The whispering sounds are sometimes broken into sobs for a brief moment, or a wail in others. You have a rising sense of unease, as if the rising voice will soon cause you to go mad if you can't locate it and get it to cease.
OOC: Anyone bring a light source?
