Ezio Auditore da Firenze

Ezio Auditore da Firenze (born 1459) was a Florentine noble during the Italian Renaissance and, unbeknownst to most historians and philosophers, a central member of the Assassin Order. A descendant of Altaïr Ibn-La'Ahad and ancestor to both Desmond Miles and Subject 16, Ezio was unaware of his Assassin heritage until the age of 17, when his father and two brothers, Federico and Petruccio, were murdered. Ezio fled Florence – his birthplace – and took refuge at the Villa Auditore in the Tuscan town of Monteriggioni.

Learning of his heritage from his uncle, Mario Auditore, Ezio began his Assassin training, as well as his quest for vengeance against the Grand Master of the Templar Order, Rodrigo Borgia, who had ordered the executions of his father and two brothers. During his quest, Ezio managed to not only unite the pages of Altaïr's Codex for the first time since Domenico Auditore, but also to save the cities of Florence, Venice and Rome from the Templars' control. He ensured the future travels of Christoffa Corombo to the "New World" and, in liberating Rome from Borgia control and preventing the rise to power of Ercole Massimo's Cult of Hermes, helped spread the Renaissance and Assassin ideals of independence and free thought throughout Italy.

Shortly before the death of Rodrigo Borgia in 1503, Ezio was pronounced the Grand Master, or "ll Mentore", of the Assassin Order.
