It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, The goliath insists that they will come back for her if they succeed, but if she makes any noise after they leave, then she won't be making noise anymore. The woman shrinks back, huffs, then angrily sits down in the cell, telling them to go.
DM: Okay. Looking about the cells, they all appear to be empty. You do catch a couple of rats skittering through some of the brush. Nothing that really is the source of that scraping metal sound.
Player: This is the second room?
DM: You go around the way and there's another set of cells.
Player: Yeah.
DM: Nobody else in the other cells.
Player: This is where I heard something before.
DM: You heard it echoing around the other hallway, so it could be amorphously from the same source that she came from, or near the cell.
