From the introduction: Wooden piers protrude out of the cliffs base, which have been covered in many crates ready to be exported to the lands to the north. A central building houses a crane used to lower heavy goods to the ground. You can hear the loud grinding of the gears and the swooshing of water as it cascades over the waterwheel nearby, giving power to the crane above. An office room of sorts has also been carved out of the cliff close to the waterwheel, which is used for storing expensive supplies, gold and the harbor masters possessions. A large storehouse has also been built into the cliff side to store long term mundane supplies.
