The circular room beyond the door is obviously used as storage. Numerous boxes, crates, and barrels line the walls in addition to unused tables and chairs in various states of disrepair. All of the containers are stamped with the crest of the Sterich house of Emondav. Some look like they are sealed while other are obviously open, although you cannot see their contents from your current position.
The room is about 30 feet (~9m) in diameter and completely circular. An archway leading to another circular chamber lies on the far side of the room. There are no other obvious exits. The next room seems to contain what looks to be a well. The far room seems to be lit by a flickering torch set into the right-hand wall. A similar torch can be found in your room, although it looks like it has burnt out completely.
In the far distance, at least 150 feet (~46m) from where you are standing, down a long corridor, you can detect a bright source of lantern light emanating from a side room. The source itself is out of view.
From your perspective, both rooms seems completely empty, except for a strong smell of mildew. In addition, the walls seem coated with heavy moisture, which is not uncommon in subterranean locations such as this.
An occasional drip of water can be heard, but otherwise the dungeon is eerily silent.
