Ange stood at the stern, casting a pollen spell on the sails in front of him. What was originally a small spell of pollination turned into a jet-stream effect due to the high frequency of casting: whoosh whoosh whoosh...
The sails, which were already taut, caused their supporting masts to creak in protest. Everyone felt a shudder beneath their feet — the airship was accelerating.
Ange continued casting his spell, the pollen relentlessly assailing the sails. He had previously discovered that when a mass of whirlwinds all surge in one direction, it results in a suction-like effect, drawing in more air in the same direction.
The larger the volume of wind, the greater the propelling force. The airship's masts let out agonized creaks as it continued to accelerate. At a certain point, the entire ship suddenly lightened.
