Steam

Borders: Order Water

The interior of the plane is pipes, pistons, whistles and vents shooting steam and conveying water all over the place, like some absurd, overbuilt Rube Goldberg Steampunk contraption.  Swarms of stout engineers with goggles and beards open and close valves and whistling vents, replace pipes, and complain that nothing ever works like it used to.

Steam has a very active level of inspiration on the material world.
