He is so not even bothered by the quiet. But Iorveth tends to be intensely serious on outings like this, finding talk to be distracting, so it suits. But they meet pretty much nothing in the way of traps, and after a few more tunnels taken, he's about to answer the question with 'nothing', until a glance to the side reveals something abnormal in the continuous smoothness of the wall. Huh. "Wait--"

Cautiously, he slows, a hand reaching up to feel along the wall until it meets a crevice. Down the indent and-- "A door."

He'd yet to see any kind of separate room aside from tunnels here, so it's definitely interesting, but barging right in would be stupid. "Does anyone have a torch?"
