Editing Ezio Auditore da Firenze (section)

===Foray into vengeance=== 

:''"The Auditore are not dead! I'm still here! Me! Ezio! Ezio Auditore!"''
:―Ezio, upon killing Uberto.

Paola agreed to assist Ezio in his quest for vengeance, teaching him how to survive in the city as an outlaw through pickpocketing and blending in crowds. She further directed Ezio to Leonardo da Vinci to repair Giovanni's Hidden Blade, though she did not notice that Ezio was being watched.

====Last rites====
That night, Ezio met with Cristina who by now had heard about the execution of his family. Together, they went to the Piazza della Signoria to recover the corpses of his father and brothers in the hopes of giving them proper last rites, only to discover that their bodies had already been removed. After beating up a guard, Ezio learned from him that the guards of the city plan to dump the bodies into the Arno. Ezio and Cristina hurried to a small dock on the river, where they found his family's bodies awaiting disposal. In his anger, Ezio initially wanted to stealthily kill all the guards at the dock, but Cristina protested, reminding him that the guards were merely people doing their jobs. Sympathizing with her conscience, Ezio was able to move each of the corpses onto a docked boat without alerting or harming any of the guards. After performing the last rites with a pyre, Ezio proposed to Cristina to flee Florence with him, but she declined due to her duties to her family. Respecting her decision, Ezio gave her his necklace as a parting memento before kissing her.

==== Adopting the Hidden Blade====
Ezio wasted no time heading over to Leonardo's workshop the following day. There, he handed him the broken hidden blade and the coded page for inspection. The engineer understood by decoding the manuscript that it was the blueprint of the blade. After Leonardo repaired the blade, a guard banged on the door and ordered Leonardo outside before viciously beating him to wring Ezio's location out of him, but Leonardo continued to feign ignorance. Ezio realized something was wrong and crept up behind the guard, killing him with the Hidden Blade before hiding the body in Leonardo's workshop.

====The first assassination====
After Leonardo had thanked him, Ezio sought out and assassinated Uberto in the courtyard of the Basilica di Santa Croce during Andrea del Verrocchio's latest exhibit. Once he had made his way into the courtyard, Ezio waited in the shadows for an opportunity to strike. After hearing Uberto and the attendant nobles deride his family, he emerged from the crowd and attacked Uberto in a frenzied rage, stabbing him multiple times in the chest, before furiously proclaiming the survival of the Auditore family—through him—to the crowd of shocked guests.

After murdering Uberto, Ezio took the documents that the Gonfaloniere had concealed from him and his father, as well as a letter from Uberto, meant for his wife and son. Ezio decided that he would see to it that she received the letter, not wishing to sink to Uberto's level.

====Discovering his heritage==== 

:''"All this talk of Assassins and Templars... it reeks of fantasy."''
:―Ezio trying to understand his heritage.

Now the most wanted man in Florence, Ezio fled the city with his mother and sister in the hopes of making their way to Spain, stopping beforehand at the Auditore family's villa in Monteriggioni for shelter. As they neared the town, the three were accosted by Vieri de' Pazzi and his followers but were saved by the timely arrival of Ezio's uncle, Mario Auditore, and his mercenaries.

Mario informed Ezio of the existence of the Assassins in an obvious attempt to induct him into the Brotherhood. He spent some time teaching Ezio swordplay and revealed that many of his ancestors, including Giovanni, were members of the Assassin Brotherhood and had been fighting the Templar Order, which had ordered the execution of his family, for centuries. However after a year of training, Ezio refused his heritage, wishing only to continue his journey to Spain for his mother's and sister's safety with the help of the skills Mario had taught him.

Dejected, Mario left Monteriggioni for the city of San Gimignano, where Vieri had been located, in an attempt to relieve Monteriggioni of continual assaults by the Pazzi's minions. Guilt-ridden and knowing his presence was a primary reason for the ongoing attacks, Ezio travelled to San Gimignano to accept Mario's offer.

When Ezio arrived outside the city, he joined Mario and his mercenaries in their assault, and they waited until nightfall to storm the city. After witnessing a brief Templar meeting between a Spaniard, Jacopo de' Pazzi, Francesco de' Pazzi and Vieri about schemes against Florence, Ezio made for his target. While Mario and his mercenaries kept Vieri's men distracted, Ezio challenged and fought Vieri for the last time, eventually overpowering and killing him after a brief duel.

Ezio tried to extract a confession from his old enemy, though Vieri chose to be snide to the very end. Infuriated, Ezio flew into a rage and insulted Vieri's corpse, continuing until his uncle calmed him down and reminded him of a tradition of the Assassins: showing respect to those they have killed and not becoming like their enemy. On his enemy's corpse, Ezio found a page like the one he recovered in his father's chest. He also found a letter from Giovanni Giocondo to Vieri's father.

Returning to Monteriggioni, Mario revealed to Ezio that the Spaniard was Rodrigo Borgia, the Grand Master of the Templar Order in Italy. Ezio then decided to track every Templars responsible for the death of his kin, beginning his quest in Florence against the Pazzi plot in the city. Before Ezio left the city, Mario showed him a wall in the villa which had scattered pages of a book laid out onto it. He explained that Ezio father and him had tried to recover and decipher the pages of the Codex of Altaïr Ibn-La'Ahad, a legendary Assassin Mentor who had a Piece of Eden two centuries ago and wrote in his codex the location of a vault with a powerful secret. Ezio saw that there were the same pages as the ones he found on Vieri and his father's chest and decided to take on the work of his father to collect all the pages and to decipher it with the help of Leonardo da Vinci.

Ezio decided to begin the renovation of Monteriggioni with the help of his sister who now worked as the accountant of the city. Mario also showed to his nephew the Sanctuary under the villa, a room that commemorated six legendary figures of the Assassin Brotherhood. In the Sanctuary, the Armor of Altaïr was locked by Ezio's great-great-grandfather a century ago. Mario explained that he had heard rumours of hidden Assassin Tombs in Italy with Assassin Seals which could unlock the armor but that he had given up on the endeavour of finding them all in his old age.
