- "Today, Cesare commands my men, but soon, I hope, we will be free."
- ―Fabio Orsini, 1500.[src]
Early life and career
Fabio Orsini was born in either 1476 or 1477, as the son of Paolo Orsini.
Affiliations with the Borgia
Around three years after the battle at Montepulciano, Fabio joined his cousin Bartolomeo d'Alviano in a fight against the Savelli family.
He was forced to continue serving the Borgia family however, as Cesare managed to cripple the power of the Orsini.
In 1500, Fabio lent an old storehouse on Rome's Tiber Island to the Assassin Order, hoping that it would aid them in their war against the Borgia. He was also aware of the fact that his cousin Bartolomeo was amongst the Order's numbers, as he had heard many stories about Bartolomeo's fellow Assassin, Ezio Auditore da Firenze.
Later, Fabio attacked Micheletto Corella's army after Cesare had Fabio's father Paolo killed. He was unable to defeat the skilled Micheletto, however, and lost his status as the leader of the army. He then became an outlaw, raiding the countryside, and a warrant for his arrest was placed on him by Rodrigo Borgia, Pope Alexander VI.
After the death of Rodrigo, and his son Cesare's fall from power, Fabio entered the newly elected Pope Julius II's service. He led the Papal armies for him, in order to arrest Cesare for murder, betrayal and incest.
In late 1503, he fought on the Spanish side at the battle of Garigliano against the French (counting among their ranks Piero de' Medici, among others) alongside Bartolomeo and Prospero Colonna. However, he died in from a head wound he received during the fight.
- Fabio's armor resembled an early design for the Papal Guards', as seen in the Assassin's Creed: Brotherhood E3 trailer, and in Assassin's Creed: Ascendance.
- Unlike the Papal Guards in-game, Fabio's armor bore the coat of arms of Pope Julius II, comprised of the Papal Keys and a shield with a golden oak tree on a blue field.
- The name Fabio is ultimately derived from the Latin word faba, meaning "bean."
