The party rests and waits on the boat while the repair spiders work away. Elizalotte takes a chunk of blue stone from one of the spiders; it simply turns around and leaves the ship to get more.
Eventually the clanking sound of the spiders' walking is joined by a low humming from the bowels of the ship; as the spiders haul more of the blue ore belowdecks, the humming gets slightly louder, and after a while the ship seems to rise a few feet.
After ten hours or so of bumming around, napping, and collecting moss, you notice that there seems to be fewer spiders on the ship. All but one of them leave, and it sidles up to Kyle, folds its legs up under itself, and its little stone pops out of its torso and lands at his feet. It sits motionless.
Surveying the repair spiders' handiwork is a somewhat surreal experience. The furniture inside the ship was untouched, but the ship itself is immaculately built. No evidence of the crater in the deck remains. The spiders even cleaned the outside of the ship; it gleams a little brighter in the mosslight, and the insignia on the side of the ship is now visible.
The ship's cockpit is now unlocked as well, unobtrusively located on the far side of the structure that leads downstairs. The cockpit has two chairs next to a table with several instruments and controls. It's all completely unintelligible, but one of the table's drawers contains the pilot's manual, which has both brief and long-winded explanations of how to operate the ship.
According to the manual though, the ship
flies. Sure enough, when you start it up, the dull humming from belowdecks turns into a roar, the ship floats twenty feet above the surface of the water, and wings unfold from either side of the ship. If you look over the edge from the deck, you can see discs that were previously hidden beneath the water. They extend beyond the side of the craft, and give off the same light as the stones the spiders had been carrying. The disks also seem to be the source of most of the noise from the ship. The ship occasionally lurches just a little, but it stays hovering in the air without major problems.
You are now able to pilot an airship! The problem is, where to fly inside an underground cave? At least there is plenty of room; the cavern's ceiling is ten ship-heights above the tallest building, and the water extends for a mile or more beyond the edge of the city, at least on this side. The airship also has some floodlights on the front, which allows you to see quite clearly in front of the ship.
