A1: Slave Pits of the Undercity
Falan, you hear the same thing as Larhart, that is, nothing at all.
Thorik, the door doesn't seem to be trapped to you. However, on closer inspection you notice severe damage on the door: the boards are cracked and charred, and the handle is deformed, as if slightly melted. You cannot see the hinges from this side, though.
As for sounds [I'm presuming this'll be part of the SOP]: there is movement, sounds of a short scuffle. Gnawing. All distant. Something hits the floor and bounces once.
