Cesarino Rossi da Venezia was born on October 5th, 1477 to Lorenzo and Bianca Rossi, members of the noble house of Rossi. He was trained by his father from a young age to become a politician. When he was just ten years old, Cesarino was sent away to his uncle Giancarlo, who lived on the outskirts of Milan. At the age of ten, Cesarino discovered that his uncle Giancarlo was not just a merchant, but also an assassin. For seven years, Giancarlo trained Cesarino day and night until he felt that he was ready. When Cesarino was seventeen years old, Giancarlo felt that his nephew was finally ready to take up the mantle of being an Assassin.
