Okay Brogg, you smite the shadow man and he collapses, dissolving in what seems to be a pool of runny tar. The room seems to brighten somewhat, revealing what Renwick discovered earlier- there is an altar and two doors in the back. The doors are ornate, carved in black stone, perhaps basalt. There are enlarged and distorted demonic faces on each, tongues hanging out grinning. The doors are locked. There is a small stone chest, also locked, on the floor behind the altar.
