Editing Ezio Auditore da Firenze (section)

===Siege of Monteriggioni===

During the journey with his uncle, Ezio told Mario what he had learned from Minerva, but also found solace in the fact that his own battles were finally at an end. Arriving at the Villa, Claudia informed him that Caterina Sforza was at Monteriggioni to ask his help. Ezio agreed to listen her after visiting the city.

During his time in the village, Ezio helped Angelina Ceresa to deliver flower for Claudia's birthday party. He also captured Mario's favorite horse which escaped from the stable. While on the wall of the fortress, Ezio shot with the new cannons to train the mercenaries.

Returning in the Villa during the evening, Ezio spoke with Caterina who asked him to send his troops to help defend Forlì against the Papal Army. Ezio agreed and reached Mario's study with where Mario, Maria, Claudia and Niccolò Machiavelli waited for him. Ezio once again retold the events of his encounter in the Vault to all of them. Niccolò, in turn, criticized Ezio for his failure to kill Rodrigo Borgia, and angrily left for Rome. That night, unconcerned with Niccolò's outburst, Ezio returned to his bedchamber to share an intimate night with Caterina Sforza. 

On 2 January 1500, Ezio and Caterina were waking up by the sound of a cannon. They believed that the mercenaries were in training until a cannonball broke Ezio's bedroom wall. Taking a sword and his father's hidden blade went on the roof and discovered that the city was being besieged. Meeting with his uncle, he was informed that this was an attack from the Borgia with the Papal Army. Ezio ran to the walls to take control of the cannons and gave enough time to the citizens to flee. As the Papal troops reached the wall, Ezio killed them.

Even with all their effort, the enemies breached the main gate of the city. Ezio saw that Mario was captured by the General of the Papal Army, who also captured Caterina and had the Apple of Eden. Seeing his uncle lying on the ground, Ezio ran across the rooftops in a vain effort to reach them, but Mario was shot down by the General. At the same moment, Ezio was shot by arquebusiers upon the city walls and fell to the ground.

Ezio, having soon regained consciousness as two of Mario's mercenaries dragged him to safety, continued to partake in the battle, which had spilled into what was left of the city streets. Ezio protected Claudia and retreat to the Villa where they stopped a thief before he closed the secret door of the study's room. Retreating to the Sanctuary, Ezio and the fleeing civilians fled through a secret passageway that had been hidden behind the statue of Altaïr Ibn-La'Ahad.

In the undergrounds, Ezio activated some traps to kill Borgia men and protected the citizens.

Arriving at the exterior of the city, Ezio informed his mother and sister that Mario was dead. After ordering them to take refuge in Florence, Ezio began to make his way for Rome. During this journey, however, Ezio passed out and fell from his horse due to the severity of his wounds.
