Ezio Auditore de Firenze was an important figure during the Italian Renaissance - unbeknownst to most historians and philosophers - and a member of the Assassin's Order in Assassin's Creed II. He is a decendent of Altair Ibn-La'Ahad and the ancestor to both Desmond Miles and Subject 16. Ezio was unaware of his Assassin heritage until he was 17 years old, when following the murder of his father and two brothers, Ezio fled from the Italian province of Florence - his hometown - and took refuge in the town of Monterigonni in the Tuscan region at the Auditore Family Villa.
After the mentoring and training from his uncle, Ezio proceeded on his quest for revenge against the Grandmaster or the Knights Templar, Rodrigo Borgia, who had ordered the execution of his father and brothers. During his 23-year quest for revenge, Ezio managed to not only The Codex pages Altair wrote, for the first time since Domenico Auditore, but also to save the cities of Florence and Venice from the Templars' wrath. Later still, Ezio was responsible for the rescue of Cristoffa Corombo, uncovering a Templar plot to discover the "New World".
