Lucian makes sure that the goblin is quite well shackled, wrists and feet both. Then he fashions a makeshift gag from another goblin's rags and puts it in place.
As Sydney takes a look into the dim room, he notices boxes, cages, and crates throughout the room. The halfling also notices a pile of armor [made of leather and chain mail] in the bottem left corner of the room. The room appears to be 15 feet across from the door, and 20 feet wide. A light drip can be heard from somewhere in the room. There is nobody to be seen in the room...
Sydney will motion the rest of the party to stay put for now and cautiously enter the room. He will inspect the pile of crates to see if any bad guys are hiding there, or if any crates or boxes are open enough to allow him to rummage through them. Unless he encounters somebody, he will proceed to the other door and check to see if it is locked.
Most boxes are locked, but a few are opened. One contains nothing but hay, another holds slave equipment such as manacles, chains, and hand-cuffs, and the third box is full of wool blankets of medium-size. All crates are locked except one, which is full of foul-smelling cheese.
Nothing is in the cages.
As you search through the room silently, you find no hidden enemy, but you do find a small barrel behind a crate, but it is locked.
