Vaporships

Since many Passionate aren't shapers, residents of the shards use vaporships for travel and trade. Vaporships come in all shapes and sizes, although most are based on First Fold designs for nautical ships or airships. Both designs take advantage of the currents of Vapor.

Unshaped Vapor is not a static fluid. Passions too slight to shape an island still create ripples, and ripples combine into currents. Vaporships use these currents when they can. When the currents aren't available or flowing the wrong direction, vaporships burn passion crystals in onboard passion furnaces, to power propellers or generate thrust directly.

Vaporships are essential to connecting the shards, so many arcanists and engineers try to improve Vapor navigation, and the construction and propulsion of the ships. In the untamed Vapor between shards, pirates sometimes prey on civilian ships, to steal cargo and/or enslave passengers. So most vaporships carry at least lightly defenses.
