Ayar Acar was the son of Tuti Cusi, a powerful and wealthy councilor of the Incan Emperor, Manco Inca Yupanqui, during the Spanish conquest of the Inca Empire in the 16th century. He was also the husband of Quila before she left him to pursue her dream of becoming a chasqui. He was one of the Emperor's favorite, working alongside his father, until the end of his marriage, which reflected badly on him and on his family.
In 1536, during the Siege of Cuzco, Ayar was visited by Quila for the first time since she left, his former wife asking for his help. She told him that she had uncovered a plot to assassinate the Emperor but that no one was believing her. Telling her that in the past she never lied to him even when he wished she would, Ayar decided to bring Quila to his father. However, Ayar's father didn't believe her since the proof had been destroyed on her way to Cusco and because he was still holding a grudge against her for leaving his son. As Ayar was arguing with his father about Quila's trustworthiness, Don Gonzalez Pardo, the drunk travel companion of Quila, erupted into the audience room, prompting Ayar's father to accuse Quila of conspiring with a conquistador. He then sentenced both Quila and Pardo to die and had the guards drag them away under the eyes of a conflicted but silent Ayar.
