Lilli travels to Mandolan with her faithful companion, the dragon Hector, after receiving a call for help from Grand Vizier Guliman. He would like to be king. However, the throne is bewitched: Every time Guliman wants to mount it, he flies back down in a high arc. Lilli is now supposed to make this throne "occupyable" again by means of a corresponding magic. But the grand vizier turns out to be a rogue who plays the wrong cards and keeps the rightful king Nandi captive in the Forbidden City.
