Sanbalet sighs and nods, "Fine," he says, "If that's what you wish, I shall give you a tour."
He leads you through the rest of the caverns, of which there's not much. You find a couple chambers with several casks of brandy and barrels filled with bolts of silk cloth that are probably worth quite a bit of gold. The most notable thing you are shown is a cave that opens directly to the sea. The tide is out at present, and there is little water in the cave, but there is an obvious high-water mark three feet above the floor. Pulled up onto the sloping cave floor is a small boat, perhaps large enough for eight people, with oars, a step-down mast, and a neatly furled sail. A rope tied to the bow is being held down by a large boulder that serves as an anchor.
After showing you everything, he stands silently, waiting for you to ask further questions.
