Autloc, High Priest of Knowledge is the most important person of the town (save, of course, for Yetaxa). Being a high priest he follows Yetaxa and continues to do so even after Yetaxa tries to ban human sacrifice (which causes Tioxatl to declare Yetaxa a false goddess and hatch a plot to poison her).In the end he is realises Yetaxa gave him false hope and he ends his beliefs and banishes himself from the Aztec civilisation, ironically this self-banishment is a blessing in disguise as he will be saved from the Spanish when they land and conquer the Aztecs.
