One man slowly moves over to the side and examines the chest. It appears sturdy and well-made, although simple and undecorated. He reaches to open it, and finds the lid unlocked, albeit rather heavy, and it seems the hinges had gone a while without oil. After exerting a bit of force, he manages it open, although the effort made him pant. Within, he sees an pouch of coins and a tinderbox. As he looked at the both of them, he began to get cross-eyed, and his vision began to blurr…

Another man silently crawled his way next to the first. Remaining on the floor, he picked up some of the books next to the chest and began shuffling through them. Hmm…some of these had an air of familiarity about them…as he flipped through the pages, looking for something familiar, he involuntarily groaned, as though in pain…

A third edged his way over to the wall. Remaining bent down, he examined the grate. Hmm…well he could see that the floor was well built, with the floor sloping from the center to the wall, to catch rain. The chain was wrapped around the grate and held fast by a padlock. All three seemed sturdy, and the chain was pulled taut, as though there were something weighing it down on the other side. Further investigation of the chain will require its own action. Looking deeper into the grate, he noticed something… Something in there dimly reflected the starlight. It was just out of the reach of his fingers, though.

One more fellow plodded over to the trapdoor and kneeled down next to it. The door seemed big enough to admit a person easily, if it were opened. Which it would surely be, but it appeared that the door’s handle had been padlocked to the floor. Hmm…the lock had a large keyhole, might not be too hard to pick, and the door itself, while the wood seemed strong, didn’t appear to be reinforced…

Finally, the last man and a lady move over to the table, and examine the bottle of wine, which appears to be the only thing on that particular table. The wine’s label contains some manner of artwork that it is too dark to make out, but above the picture you can make out a word, Margeaux. Why does that name sound familiar… Anyway, the bottle appears to be about half-full of good wine. One would only need remove the cork first.

As all of your heads begin to clear, you notice something. The wall, which is a bit higher than chest-height, appears to have gaps in it at regular intervals. The term "parapets" comes to mind. And the horizon appears to be farther away than it ought. You get the sensation of having some level of altitude, although none of you have looked over the parapets yet...
