Rise to power
Sometime between 1494 and 1497, the Guard Captain met Girolamo Savonarola and, drawn by his promises of power, agreed to become one of his nine lieutenants.
Each lieutenant had the duty to restrain the citizens of Florence, and prevent them from starting riots. The Guard Captain stationed himself with his guards in the courtyard of the Basilica di San Lorenzo - the final resting place of several members of the Medici family - and ambushed and killed any Medici sympathizers who came to the Basilica.
In 1497, at the height of the Bonfire of the Vanities, Ezio Auditore wandered into the Basilica, and was curious to find it silent and deserted. The Guard Captain swiftly made himself known, and greeted the Assassin as "another challenger."
As he watched from a scaffolding, the Guard Captain sent down several of his Agile guards, as well as signaled for his archers to fire. As the fight progressed below him, the Guard Captain spoke of how well his plan was working, and that he had trapped and killed many Medici supporters; even mentioning one who had taken down almost three dozen of his guards before being killed in action.
However, the Assassin managed to dispatch the soldiers, and climb the side of the building, where he began killing the archers to reach the Guard Captain himself.
Though his men were dead, the Guard Captain scoffed at Ezio's attempts to face him, claiming he had been "born for battle." The two then fought on the roof of the Basilica, but after a struggle, the Guard Captain was killed.
In his final moments, he was shocked to realize how proud and cruel he had been, and admitted that he had been intoxicated by power.
