Airship

This vessel floats above the ground, held aloft by a balloon filled with magic gas. The balloon sits within a wooden or metal frame, beneath which is a boat-shaped cabin that holds the crew, the passengers, and the cargo.
    Although most airships are powered by a magic propeller, some resemble sailing ships and are driven by magically created winds. An airship requires a crew of five (in addition to the pilot) to fly effectively. Including the gas balloon, this vessel is 8 squares long, 4 squares wide, and 6 squares tall.
