Claudia Auditore da Firenze

Claudia Auditore da Firenze (born 1461) was a Florentine noblewoman during the Italian Renaissance. She later became a member of the Assassin Order.

Early life
Claudia Auditore da Firenze was born in Florence, the daughter of Giovanni and Maria Auditore da Firenze and sister to Federico, Ezio and Petruccio.

In 1476, Giovanni, Federico and Petruccio were executed as they were accused of treason against Florence. In fact, they were executed by the Templars, the sworn enemies of the Assassins, the latter of whom her father was a member of. Following this, her brother Ezio exacted revenge on Uberto Alberti, the city's Gonfalioniere, and left Florence with Claudia and their mother. They fled to Monteriggioni, the city ruled over by their uncle Mario.

Although Ezio at first meant only to stay in Monteriggioni for a day, he decided it was best to stay at the Villa Auditore so that he could finish his father's work.

Monteriggioni's treasurer
Mario assigned Claudia to being Monteriggioni's treasurer, keeping track of all of Monteriggioni's incomes and objects Ezio brought in from the outside.

Claudia also married Mario's finest mercenary and the two eventually had at least one child.

Claudia most likely started her training to become an Assassin as well during these years.

Member of the Assassin Order
In January of 1500, Ezio, along with Mario and other family friends were preparing for Claudia's birthday party, but the town of Monteriggioni was besieged by the Borgia, the most prominent Templar organization, under the command of Cesare Borgia. As a result, Mario was killed and Ezio left for Rome, the Templars' headquarters, to exact revenge. Ezio told her and her mother to go to Firenze, but feeling obligated to do so as well, Claudia followed Ezio to Rome. There she took control over the brothel and the courtesans to help her brother in locating Caterina Sforza.

She assisted her brother in assassinating Juan Borgia by attending the latter's pagan party with her courtesans. As she revealed herself, she was suddenly attacked by a Borgia guard. However, Claudia killed her attacker immediately.

After the event, Claudia, in her brother's recommendation, joined the Order of Assassins.

Characteristics and personality
It is evident that she had been too spoiled by Giovanni, unafraid to be violent when a girl "looked at her boyfriend" and at times immature, such as when Mario assigned her to manage Monteriggioni's finances. Due to her violent streak, Giovanni had to raise her dowry by 1,000 florins because she scared off all of her suitors.

Regardless, Claudia was very capable of handling and keeping track of the town's bankroll and her brother's purchases and earnings. Her capability in business management again came to play when she volunteered - despite Ezio's initial protest - to take over the brothal in Rome when its previous owner was killed, and under her management it turned from a run-down joint to the most popular brothal in Rome, as well as a far more effective intel-gathering arm for the Order of Assassins.

She was also kind with her family, being especially emotional over her father and brothers' execution and her mother's emotional trauma.

Trivia

 * Claudia, as with most of the characters, appears not to age over the course of the Assassin's Creed II. She remains at the same desk in the Villa Auditore for 23 years. After she complained about being put to work, her only interaction with Ezio was asking if he was "... [there] to look at the book" of finances.
 * Claudia, along with her mother, are one of the few female characters that doesn't age through the game.
 * She was Ezio's only sister and unlike her brothers who were executed in order for Rodrigo Borgia to prove a point to Ezio, she was spared, likely because of her gender.
 * When Ezio started earning income from Monteriggioni, Claudia stated she would keep any money past the chest's maximum capacity (based on your collectibles and renovations to Monteriggioni), with no explanation of what she intends to do with all that money.
 * Although she is always sitting in the Villa Auditore most of the game, she along with Maria, appear in the "memory" Ezio has at his home during the Bonfire of the Vanities.
 * In Assassin's Creed: Brotherhood, it seems that Claudia has aged quite considerably from when she appeared in Assassin's Creed II.
 * Claudia will take on a bigger role in Assassin's Creed: Brotherhood as she was able to kill a Papal Guard singlehandedly and aides Ezio in the Assassination of Juan Borgia.
