Sofia Sartor was a Venetian-Ottoman bookshop owner and literary enthusiast. Though born in the city of Constantinople, Sofia was forced to leave for Venice during 1499, when the Ottoman-Venetian war began.
Sofia eventually returned to her birthplace in 1507 to run a bookstore at the old Polo trading post. During 1511, she met the Assassin Ezio Auditore da Firenze, the man who would eventually become her husband and the father of her two children.

A polylingual, multicultural, and intelligent woman mature beyond her years, Sofia had a passion for literature, which fueled her decision to run a bookstore, in hopes of sharing the democratizing effect she felt in books with others.
