The merchant Christopher de Haro helped Faleiro and Magellan present their proposal before the Spanish royal counselors.
Faleiro planned to accompany Magellan on his voyage around the world. However, it is said that on the evening prior to embarkation, Faleiro worked out his own horoscope for the voyage. The stars predicted a violent death. Consequently, he remained behind. Other sources claim he went mad before the voyage, and thus did not join the expedition.
