the spellbinders travel large distances in their metal flying ships. unlike aeroplanes, which operate on aerodynamic principles, flying ships generate lift through powerful magnetic fields. each flying ship is equipped with a pair of large power stones on either side, which rotate slowly as the ship moves. this motion creates a magnetic field powerful enough to repel against another magnetic field created by the summoning towers. flying ships can be used for transportation and also to dust crops with pesticide. although the technology that powers them is impressive, flying ships generally move somewhat slowly. by the time of paul's visit to the spellbinder's world, only six remain in operation.
