|First Appearance:||The Hanged Man|
Publicly, Lord Girolamo Riario, Count and Captain-general of the Holy Roman Church, is known as Sixtus’ nephew. Only a select few are aware of his true lineage, and like Leonardo, he has a desire to cement his position and legitimacy in society.
Although dedicated to the Holy See, he perceives Pope Sixtus to be guided by more worldly desires and selfish indulgences, while he himself is driven by a pure belief in the Divine. Nevertheless, Riario gladly leads the mission to destroy the Medici's, as he sees Florence as a prime example of the rapid deterioration of holy ideals in Europe. He is ruthless and unwavering—utilizing every resource at his disposal.
- Illegimate son of: Pope Sixtus IV
