The children go off with the priest to the mountain, but in the meantime Mendoza learns that the priest is an impostor and that the real one died years ago. Instead, the masked man was a traveler who came from the sea, and Mendoza realizes that the man is Esteban's father. Reaching the mountain, the priest continues on alone after bidding Esteban goodbye. As the City of Gold crumbles, Gomez and Gaspard are killed trying to horde gold. Elsewhere, the priest finds the reactor and inserts the jar. In a flash of energy the machine stops, but the priest's fate is uncertain. In the end, the City of Gold is destroyed, but the children still have the Golden Condor. Esteban, Zia and Tao decide to fly west to find adventure in the Pacific Ocean. In the meantime, Mendoza promises to see Esteban again – perhaps one day in the Barcelona tavern where they first met.
