Zia is the daughter of an Inca priest Papa Kamayo . She was taken away from he father by Governor Pizzaro because she has the ability to translate the Quipu which is a form of communication by the Incas using strings and knots in them.

Zia has the Medallion of the Sun (like Esteban) which is a key to the Cities of Gold. It was handed down from generation to genaration of her family. She is a kind and caring person but tends to judge all Spaniards the same. Unlike Esteban who trusts Mendoza, Zia think he is just after one thing, Gold.

Zia is a brave person since she has risked her life on many occasions such as when she gave herself up to the Spaniard to save the Mayan Village, but she believes that friendship is the most important than the Cities of Gold when she allows the Olmecs to enter the City of Gold to save Tao's life.
