20

The children fly back to the City of the High Peak to speak to Chief Kraka about the land of the Mayas. Along the way, they spot Gomez's army moving their cannon over a wooden bridge. Esteban dives twice, unsing the flying ship's wings to cut down the bridge. The cannon is, thus, lost in the river. Gomez's forces make it to a waterfall, which hides a secret entrance to the city, and use gunpowder to blast it open. The explosion, however, causes the waterfall to collapse which washes the rest of Gomez's men away. The children land on the city where the seer Myuca tells them to find the Papacamayo of Puna, a priest who journeyed to the land of the Mayas in search of a magical fountain. Zia realizes that the man Myuca speaks of is her father. Mini-Documentary: Gold fever in present-day Brazil. (Source: Wikipedia)
