Entering the main hallway, you see that there is a single room that opens up into a circular atrium - filled with grain. Many sleeping goblins are sprawled out on the wheat, sleeping soundly. You count maybe eight of them, though there may be more.
There is a spiral stair case that wraps around the circular walls, that seems to make it's way to an upstairs office.
The whole silo reeks of filth, offal, and blood. It appears the goblins have been here for at least a few days - some of them have taken to drawing horrid little pictographs on the walls, consisting of goblins tearing apart gray-scarved thieves. Many pictures involve crowds of goblins holding a white circular object over their heads triumphantly, while the human thieves fall to the ground, dead.
There is also a picture of the goblins giving the white object, as well as mounds of treasure, to some creatures that may or may not be goblins (only about ten times as large). It's hard to tell, since the drawings are crude at best.
