Eduardo is a local Peruvian Indian guide, descended from Inca heritage. Eduardo is Catholic but also fiercely loyal to his cultural roots, Maturin reflecting that Eduardo's Catholicism is not entirely correct in principle. Eduardo is exceptionally intelligent and possessed of the great strength and vigor of a young man leading an always-active life. Eduardo is quite educated about the local plants and animals, knows a great deal about geology and meteorology, and has traveled widely throughout Peru, especially in the high Andes.
