Ptolemy XV Philopator Philometor Caesar (47 BCE – Unknown), better known as Caesarion (Latin: Little Caesar), was the last Pharaoh of Egypt. He was the eldest son of Queen Cleopatra, and the alleged biological son of Roman consul Gaius Julius Caesar, after whom he was named.
Born in 47 BCE, Caesarion moved to the Roman Republic with his mother, living in the outskirts of Rome. In 44 BCE, Caesar was assassinated by a group of Hidden Ones led by Aya, Marcus Junius Brutus and Gaius Cassius Longinus. A few days later, Aya confronted Cleopatra in her residence when she was playing with Caesarion. When Cleopatra questioned Aya's actions, the Hidden One drew her Hidden Blade, which caught the attention of Caesarion. Before leaving, Aya threatened Cleopatra to do her job as pharaoh of Egypt, who later embraced Caesarion.
By 30 BCE, Caesarion had moved back to Egypt and resided in the royal palace in Alexandria. With the invasion by Augustus imminent, Cleopatra had her guards trained Caesarion in preparation for battle.
However, after Aya convinced the besieged Cleopatra that the best way to save Egypt was to take her own life, the Queen asked the Hidden One to protect and train Caesarion. Amunet gave her word and took the young man with her. With the help of Phoxidas, they departed Alexandria and set sail for Rome.
