Aldo

"Grazie a Dio! Grazie a Dio!"

―Aldo thanking Ezio after being rescued.

Aldo was a thief of the Roman Guild, under the leadership of La Volpe. He had at least one brother, who was also a member of the guild. According to his brother, Aldo was a mere pickpocket, who had never harmed anyone.

In the 16th century, Aldo was captured by the rival Cento Occhi thieves, who planned to execute him. His brother quickly met Ezio Auditore, Mentor of the Assassin Order allied with his guild, and requested him to rescue his brother.

Ezio agreed, and managed to intercept the Borgia crossbowmen just before they killed him. Aldo fervently thanked God for having Ezio save him, and soon returned to his brother.
