go for the key

Samora goes down the tunnel the goblin went with the key, being careful to be quiet. She soon stops seing a fire up ahead, three goblins sitting around it, the one with the key facing away from Samora, talking to the others. If she is careful she might be able to sneak up and cut the key loose without ever being noticed.

Or Samora could pull her pistols out and kill the goblins, it would be loud, and that would attract other goblins...if there were others.
