There is no sound from behind the door. You open the door and find yourself in a small room, lit by a single Everburning Torch. Under this torch a faded message reads "Real fire forbidden". The room is filled with dirty beakers and other alchemical equipment, a lot of it broken. Most of it sits on shelves, but the floor has its fair share of shards and bent iron. A big circular corrosion mark sits against the door and on the floor, right where you get in (ie, you can't see the corrosion mark on the door until you are in the new room.). Two more doors other than the one you just came in from are in this room. One is marked with a bronze sign. Deepwinter, Tycho and Diactum know that this is a signal for "caution". The other door bears no special markings.
